Definitions

  • the present invention relates to a control valve arrangement according to the preamble of claim 1.
  • Such control valve arrangements are mainly used in domestic water systems. There they are generally used in a fresh water supply line, which supplies the boiler with fresh water.
  • a control valve arrangement essentially consists of a housing with a check valve and a safety valve arranged therein. The two valves are functionally connected in series in such a way that the safety valve is located behind the check valve when viewed in the flow direction of the fresh water.
  • the task of the check valve is to prevent water from flowing out of the boiler back into the fresh water supply.
  • the safety valve which is functionally closer to the boiler, ensures that the water expanding due to the heating of the boiler does not exceed a certain limit pressure that can be set at the safety valve, and that the safety of such a system is thus guaranteed.
  • control valve arrangements are constructed in such a way that the part of the housing in which the check valve is arranged is designed as a line intermediate piece, and that this part is installed in the fresh water connection line of the boiler.
  • a radial outlet is provided on this housing part, from which a T-shaped branch line branches off.
  • this branch line is then inserted from above the safety valve arrangement, while there is an outlet, axially aligned downwards, via which water which is under too high pressure and drained from the safety valve arrangement can flow off.
  • Such an embodiment Due to the axially aligned arrangement of the check valve and the safety valve together in one structural unit, the space requirement of such a control valve arrangement can be optimized. Such an embodiment also has the advantage that there is no longer a branch line for the safety valve.
  • a preferred embodiment of the control valve arrangement provides that both the check valve and the safety valve are fastened to a central supporting body, which also has a corresponding fastening thread. With this thread, both valves can be attached to a corresponding thread of the housing. Such an embodiment has the great advantage that the two valves can be removed or replaced particularly quickly in a simple manner.
  • auxiliary body provides an auxiliary body.
  • this auxiliary body has a tubular extension facing the safety valve, which has an end face designed as a sealing surface for its valve body, and which furthermore has a tubular extension facing away from the safety valve and whose cylindrical outer surface simultaneously is designed as a guide for the valve body of the check valve. Since this auxiliary body thus combines two important functions, it is preferably screwed into the supporting body so that it can be easily replaced or cleaned as a result.
  • both the check valve and the sealing body of the safety valve are fastened in the supporting frame by means of threads.
  • This control valve arrangement has a two-part housing 71, 72.
  • the check valve 74 is accommodated in the main housing 71, while the safety valve 76 is arranged in the branch housing 72.
  • the branch housing 72 has a radial housing extension 73 which is screwed into the main housing 71.
  • the main housing 71 is screwed into a fresh water line 78 by means of two union nuts 80, 81. It can be seen from this illustration that in the event of a defect in the check valve 75, or for cleaning the same, the entire control valve arrangement must be removed from the fresh water line 78. This is of course associated with a correspondingly great effort and is hardly feasible for the layperson. It can also be seen from the illustration that individual parts can hardly or only be replaced with great effort.
  • FIG. 2 shows a first embodiment of a control valve arrangement according to the invention.
  • This essentially shows a housing 1, a support body 20, a check valve 3 and a safety valve 5.
  • the support body 20 has a central bore 22.
  • the check valve 3 is inserted into the support body 20 from the lower side, while the safety valve 5 is inserted into the support body 20 from the upper side, so that the two valves 3, 5 are axially aligned with one another are arranged.
  • the check valve 3, the safety valve 5 and the support body 20 together form a structural unit which is screwed vertically into a corresponding thread of the housing 1 by means of a thread 19 provided on the support body 20.
  • a sealing ring is attached to the shoulder-side end of the thread 19.
  • the housing 1 is screwed into a fresh water line 6 by means of two union nuts 8, 9.
  • This fresh water line 6 has an inlet 10 for fresh water and an outlet 11.
  • a boiler is generally connected to the outlet 11, but this has not been shown here for the sake of clarity
  • the check valve 3 consists essentially of a valve body 30 and a sealing body 31.
  • the valve body 30 has a cylindrical blind bore 41 on its rear side. On its front part, a sealing lip 34 is provided which surrounds the valve body 30 and is fixed in its position by means of a cap 36. The cap 36 in turn is fixed by a screw 37 which is screwed to a nut 38 inserted in the blind hole 41.
  • the sealing body 31 is screwed into a corresponding thread of the support body 20 by means of a thread 44.
  • sealing rings 42, 43 are provided, which each enclose the sealing body 31 and the supporting body 20 at their lower ends in annular grooves. Furthermore, the sealing body 31 has radial channels 40 and a lower, inner and bevelled sealing surface 33.
  • the safety valve 5 essentially consists of the actual valve body 50 which is attached to a valve rod 54 and is guided through it.
  • the plate-shaped valve body 50 has a sealing ring 52 on its underside.
  • the valve body 50 is biased by a spring 55 acting on the valve rod 54.
  • This spring 55 is supported on a plate 58.
  • This plate 58 has a thread, by means of which it is fastened in a housing 51 surrounding the safety valve 5 and by means of which it is adjustable in its vertical position, so that the prestress of the spring 55 and thus of the valve body 50 can thereby be set.
  • Sealing disk 57 is provided at the lower end of the safety valve housing 51.
  • an auxiliary body 23 is screwed into the supporting body 20 by means of a thread 18.
  • the auxiliary body 23 has a sealing ring at the shoulder-side end of the thread 18.
  • this auxiliary body 23 has, in relation to a longitudinal central axis 7 leading through the structural unit, a tubular extension 24, 25 on each end face.
  • the lower extension 25 is designed such that its cylindrical outer surface 27 is in shape and position with the blind bore 41 of the valve body 30 corresponds and thereby serves as a guide.
  • a spring 29 is also supported, by means of which the valve body 30 is biased.
  • the upper extension 24 of the auxiliary body 23 is designed such that its end face 26 corresponds in shape and position to the valve body 50 of the safety valve 5, so that the sealing ring 52 of the valve body 50 rests flat and a corresponding seal is created.
  • An inlet chamber 13, an outlet chamber 14 and a reflux chamber 15 are present in the housing 1.
  • two control ports 17 are provided in the housing 1.
  • the fresh water flowing in via the inlet 10 first arrives in the inlet chamber 13.
  • the water flows from the inlet chamber 13 via the check valve 3 into the outlet chamber 14, since the safety valve 5 is closed in the idle state. From this outlet chamber 14, the water can finally reach a boiler (not shown) via outlet 11.
  • the valve body 30 of the check valve 3 is moved downward by the spring preload.
  • the valve body 30 closes the first passage 46 by means of the sealing lip 34 now resting on the sealing surface 33 of the sealing body 31. If the boiler is heated up, the water in it expands. As a result, the pressure of the water rises accordingly, so that there is a higher pressure in the outlet chamber 14 than in the inlet chamber 13.
  • the check valve 3 prevents the pressure between the two chambers 13, 14 from being able to equalize, since the valve body 30 of the check valve 3 which is subjected to the higher pressure on its rear side now increases the first passage 46 with an approximately proportional increase in the pressure difference Power closes.
  • the safety valve 5 comes into action.
  • the valve body 50 of the safety valve 5 is acted upon by the pressure prevailing in the outlet chamber 14 via the radial channels 21 of the support body 20 and of the auxiliary body 23.
  • the valve body 50 moves upward.
  • the water can flow out from the front of the upper extension 24 of the auxiliary body 23 into the reflux chamber 15, so that the pressure in the outlet chamber 14 is thereby reduced.
  • both the check valve 3 and the safety valve 5 are subject to a certain amount of wear, it is important that the two valves 3, 5 can be replaced quickly and easily in the event of a defect, damage or the like.
  • This is the case with the present embodiment since the entire structural unit is fastened in the housing 1 by means of a thread 19 present on the support body 20. This means that the entire assembly, even by a layperson, can be easily replaced. Since all essential components are also fastened by screw connections, the dismantled unit can be dismantled in the simplest way the defective or damaged components are replaced and the assembly is reinserted accordingly.
  • FIG. 3 shows an embodiment variant of the control valve arrangement.
  • the entire structural unit of the control valve arrangement is identical to that in FIG. 2.
  • the difference of this embodiment from the previous one lies in the design of the housing 101 and in the installed position of the control valve arrangement.
  • the housing 101 in turn has an inlet chamber 113, an outlet chamber 114 and a reflux chamber 115.
  • a first passage 106 is in turn present between the inlet chamber 113 and the outlet chamber 114 and a second passage 107 between the outlet chamber 114 and the reflux chamber 115.
  • the structural unit formed from the check valve 3, the safety valve 5 and the support body 20 is inserted into the housing 101 at an angle deviating from the vertical, in this case approximately 45 °.
  • the housing 101 has a flange 102 protruding from the longitudinal center axis of the housing by 45 °, in which the structural unit can be fastened by means of the thread 19 provided on the support frame 20.
  • the inlet chamber 113 has a curvature upwards, so that its upper inner surface 104 comes to rest on the sealing body 31 of the check valve 3.
