Description

Mixing water regulating valve for solar water heater

technical field

The utility model relates to a valve, in particular to a water mixing regulating valve used for a solar water heater.

Background technique

There are mainly two ways to adjust and control the water supply and mixed water of solar water heaters: electric control type and mechanical type. The electric control type uses a solenoid valve, that is, the valve is turned on and off through the reversing of the positive and negative terminals of the voltage, and there are two power supply modes: an external battery and a direct connection to the mains; the mechanical type uses a combination of one or more regulating valves. Get up to control and adjust, mainly manually.

In order to promote and popularize solar water heaters better, make full use of solar energy. It is necessary to innovate and develop the supporting components related to solar water heaters, so that people can feel the comfort and convenience of using solar energy, and increase people's enthusiasm and participation in using solar energy. Adopt electric control mode in the existing solar water heater regulating valve, i.e. solenoid valve. It consumes electricity and has a short service life, more faults, and is expensive; and a regulating valve that uses one or more regulating valves for regulation and control, because there are many regulating valves, the processing difficulty of the valve seat and the number of openings will be corresponding In this way, the weight and scale of the valve are relatively large, and the material is also many and the appearance is not beautiful. The realization of the function needs to adjust several valves at the same time.

Detailed ways

Below in conjunction with accompanying drawing and the specific embodiment that inventor completes, the utility model is described in further detail.

Referring to the accompanying drawings, the mixed water regulating valve used for solar water heaters includes a regulating valve. The structure and assembly of the regulating valve are shown in Figure 1. Starting from several aspects, the structure of the moving valve plate 8 and the static valve plate 9 of the spool in the regulating valve and the related valve core shell 5, bracket 4 and valve seat 13 have been improved and designed, that is, the static valve plate There are two symmetrical openings 15, 16 and a circular opening 17 on the 9, and a groove 18 on the moving valve plate 8 matches with the opening on the static valve plate 9, and the valve plate is made of Al ₂ O ₃ 95% ceramic material. There are two stoppers 20, 21 on the circumference of the bracket 4, and a stopper 19 on the spool housing 5. The cooperation between the spool housing 5 and the bracket 4 can ensure that the maximum rotation angle of the movable valve plate is 135°. There are three threaded holes A, B and C on the valve seat 13 of the regulating valve, which are respectively the cold water pipe interface A, the solar water heater pipe interface B, and the shower nozzle pipe interface C.

The mixed water regulating valve of the solar water heater of the utility model has good regulating effect, easy control of the water quantity, and no leakage of the valve. When the movable valve plate 8 rotates with the handle 1, it can quickly adjust the hot and cold water, and the mixing of the hot and cold water is quite uniform, and there will be no phenomenon that the water is cold and hot at the same time, or half cold and half hot. You need to adjust to a temperature that you feel comfortable with. When the handle 1 is lifted or pressed down, that is, the pull rod 2 rotates around the fulcrum 14, at this moment the movable valve plate 8 moves with the dial 7 to realize the adjustment of the water volume, and the user can adjust the water volume according to his needs. When the solar water heater needs to be filled with water, the handle 1 is rotated in the designated direction, and when it reaches the designated position, the handle 1 is lifted to the limit. When you want to turn off the water after filling or water, you only need to press down the handle 1 to the limit position. When it is desired that the water outlet is all cold water from the tap water pipeline or all the hot water from the solar water heater, as long as the regulating valve is not in the shut-off state, the handle 1 can be rotated to the corresponding position.

Example:

The utility model is applied to a mixed water regulating valve of a solar water heater, and has achieved a good regulating effect. When the handle 1 of the regulating valve is perpendicular to the vertical direction and the handle 1 is pressed to the lowest position, that is, parallel to the installation plane, the valve is in the closed state; when the handle 1 is lifted upwards, the valve is opened, and water flows out of the shower , the size of the water flow is adjusted by the angle between the handle 1 and the installation plane, that is, the size of the water flow is proportional to the lifting angle, and the maximum lifting angle is 45 degrees. When the valve is in the open state, the handle 1 can be rotated up and down to adjust the water temperature. When it is rotated upward, the water outlet temperature of the shower will rise; when it is rotated downward, the water outlet temperature of the shower will be lowered. , if the handle is parallel to the installation surface as a reference, when it is rotated to the limit position, that is, when it is rotated 45 degrees downwards, the passage with the solar water heater is cut off at this time, and the shower outlet C of the regulating valve is only connected to the valve plate. The water inlet A of the running water is connected, which realizes the supply of running water. Similarly, when the same angle is rotated upward, the water outlet C of the shower of the regulating valve is only connected to the water inlet B of the solar water heater through the valve plate, which realizes the supply of high-temperature water. When the valve is in the closed state, turn the handle up to the limit position, that is, when the handle is parallel to the vertical direction, and lift it up to the limit position, the tap water port A on the valve seat is connected to the solar water heater port B, and the other ports are is cut off, so that the water supply function of the solar water heater can be realized, and the water supply speed is very fast.

The mixing water regulating valve of the solar water heater of the utility model is made the same as the existing regulating valve, without increasing the cost, and can realize the water supply function, the water temperature adjustment function, the water volume control function and the water mixing function of the solar water heater; In the case of mixed water, the outlet water can also be all cold water from tap water pipes or all high-temperature hot water from solar water heaters, so as to better meet the requirements of users for different water volumes and water temperatures. It has complete functions, convenient adjustment, simple operation, good adjustment effect and beautiful appearance.
