Abstract
The utility model relates to an exhausting and water-stopping device for a water heating radiator. The inner side of the existing radiator provided with the radiator plug of an exhaust valve is provided with an exhausting and water-stopping device controlled by the water level of the radiator. The exhausting and water-stopping device is composed of a valve comprising a cylindrical valve body, a valve core, an air inlet and an air outlet, a heavy hammer and a floater. The exhausting and water-stopping device not only can obtain the aim of exhausting air, but also can avoid stealing water, and the safe operation of boilers can be ensured. The exhausting and water-stopping device has simple structure and convenient installation and operation.
Description
The utility model relates to a kind of air draft sealing valving that is used for water heating radiator.
In existing water heating system,, outlet valve is installed at the plug of radiator in order to get rid of the air that is detained in the radiator.Its deficiency is, this outlet valve equally also can discharge water, and some resident families connect hot water from outlet valve and use, and also has the user to open to forget behind the outlet valve to close, and makes the undesired dehydration of water heating system.So not only need to waste energy to system water supplement, increase the heating cost, and this dehydration is irregular follows, management brings difficulty to boiler attendance, and a carelessness will cause the accident slightly.In order to prevent above-mentioned phenomenon, have the people once to release the sealing valve that leaks informaton, but it is mounted in the radiator outside, this type of valve cost height, poor reliability, resident family is easy to it is backed out the use that discharges water, so still can not stop water phenomenon steathily, this valve also fails to be used.
It is a kind of simple in structure, easy to install that the purpose of this utility model is to provide, and can stop the heating installation air draft water cut-off device that the water phenomenon is stolen by resident family again.
Technical solution of the present utility model is that the heating installation that exhaust valve is installed at existing radiator is stifled inboard, and an air draft water cut-off device by water level control in the radiator is installed again.This device comprises by cylinder shape valve 10 and spool 11 and suction port 9, and the valve that air outlet 4 is formed is characterized in that the side of valve body 10 has two along the locating slot 7 of circumference around a circle.Hang a positioning ring 6 on the locating slot 7 respectively, the fixedly connected weight 5 in the lower end of positioning ring 6, the outer end of spool 11 flexibly connects with a right angle arm of the lever 14 that curves the right angle, fixedly connected float 15 on another right angle arm of lever 14, and the top, right angle of lever 14 is connected with weight 5 by axle 13.
In this programme, be equipped with the limited screw 12 that is used to limit movable space between weight 5 and the valve body 10 on the weight 5,4 top is equipped with and is used to stop the user by opening exhaust valve 11 in the air outlet, spool is disclosed and is reached the steathily valve body end face stifled 3 of water purpose.
When the utility model uses, valve body air outlet 4 one ends are installed to heating installation by screw thread block up 2 inboard, air outlet 4 is connected with the suction port of the stifled outboard row air-valve 1 of heating installation, then stifled being screwed on the radiator of heating installation got final product.In the utility model, spool, float and lever are to be installed on the valve body by the suspension arrangement that weight, positioning ring, locating slot are formed, so when installing, where be screwed to no matter heating installation is stifled, the weight band float and is in sagging working position all the time, installs and uses very convenient.When in the radiator air entrapment being arranged, float falls by deadweight, lever sways and drives spool to outer displacement, thereby the sealing between breakdown spool front end and the air outlet, gas is discharged under hydraulic action smoothly, along with gas is discharged, water level rises, and float floats rising gradually, by lever spool is advanced inwards simultaneously, when rising to upper limit position, promptly gas has been arranged, when circulating water is full of radiator, the air outlet is blocked, make valve closing, water just can not be discharged, thereby has reached air draft and the effect of sealing.When the user opens the exhaust valve of radiator outside, the air in the radiator can only be emitted, and can not discharge water, stifled because of user's heating installation of not opening, stop the purpose of water phenomenon steathily so reach, the user forgets when closing bleed valve, also can not cause a large amount of dehydrations.In a word, the utlity model has simple in structure, easy to install, reliable performance, and can stop to steal water and undesired phenomenon of losing water, guarantee the hot water space heating boiler safe operation, energy saving.
Following accompanying drawing has been described an embodiment of the present utility model.
Fig. 1 is structure of the present utility model and scheme of installation;
Fig. 2 is an A-A sectional view among Fig. 1;
Fig. 3 is a B-B sectional drawing among Fig. 1.
Below in conjunction with accompanying drawing the utility model is described in detail.Valve body 10, spool 11 are to be made by copper or heat-resistant engineering plastic among the figure, and weight 5 is made by slug, and float 15 is made by foamed plastics.Valve body 10 and spool 11 are cylinder bodily forms, the concentric assembling.The inner end conical surface of spool 11 and the air outlet on the valve body 10 4 form able to turn on or off sealing surface.9 is suction port among the figure, is in the perforate of the side of valve body 10, and air outlet 4 is through holes of axially opening along valve body.Open two along the locating slot 7 of its circumference in the side of valve body 10, hang the fixedly connected tup 5 in lower end of 6, two positioning rings of positioning ring of a metalloid packing ring on the locating slot 7 respectively around a week.Vertically open two tapped holes from the bottom and the valve axis of weight 5, mix the limited screw 12 that is used to limit movable space between weight 5 and the valve body 10 on the tapped hole.Weight 5 is suspended to after the locating slot 7 by positioning ring 6, adjust limited screw 12, making the limited screw 12 and the spacing of valve body 10 is that relative movable space, no matter how weight rotates around valve body so can not split away off less than the degree of depth of locating slot 7 yet between weight and the valve body.This structural type makes this device assemble, and uses all very convenient.The outside of valve body 10 is stretched out in the outer end of spool 11, and flexibly connect with a right angle arm of the lever 14 that curves right angle type, they can flexibly connect by bare headed screw, in the present embodiment, be that outer end car with spool 11 becomes concave station, a right angle walls of connected lever 14 is made shift fork shape, and shift fork is inserted on the concave station of spool and can flexibly connects, the purpose that flexibly connects is the rotation that produces when offsetting lever action, and only spool 11 is passed in Horizontal displacement.Another right angle arm of bell-crank lever 14 is fixedlyed connected with float 15, and top, the fulcrum right angle of bell-crank lever 14 is connected with weight 5 by axle 13.In order to prevent that further the user from disclosing out spool 11 with elongate tool, the passage of air outlet 4 is made bend, in the present embodiment, be in the air outlet 4 channel outlet that the valve body end face is housed is stifled 3, air outlet 4 is blocked, become bend from the perforate of passage side again.
