How to repair the hot and cold water mixing valve in the bathroom if it is not hot water

Just change the mixing valve, it's not too expensive. Mixing valve, is a valve that mixes hot and cold water, which is widely used in electric water heaters, solar water heaters and geothermal heating water systems.

Users can adjust the temperature of hot and cold water mixing according to their needs, and the required temperature can be quickly reached and stabilized to ensure that the water temperature is constant, and is not affected by changes in water temperature, flow rate and water pressure, so as to solve the problem of hot and cold water temperature in the bathing center. A temperature-regulating mixing valve, it comprises a valve body with a hot water inlet, a cold water inlet and a mixed water outlet, a valve core is arranged at the intersection of the middle part of the valve body, a handle is fixed on the valve stem of the valve core, a adjusting screw is arranged on the valve body outside the valve core, the adjusting screw passes through the valve body and is connected with the rotating body of the valve core, a flow regulating device is equipped with a flow regulating device at the water inlet, the flow regulating device is provided with a pipe joint connected with the water inlet, a piston is arranged in the pipe joint, the piston is also equipped with an adjusting body on a sliding ground, and a flow regulating hole is opened on the wall of the adjusting body, A compression spring is installed between the adjusting body and the outer edge of the piston. When the water temperature is adjusted, the rotating body of the valve core is fixed by the adjusting screw, then the water temperature changes without mismovement, and there is no need to re-adjust it when it is used next time, and the flow adjustment device is also installed at the water inlet to ensure that the water inlet remains unchanged, so as to keep the water temperature constant.

The core part of the so-called mixing valve is actually two porcelain tiles that can be dislocated from each other, which is rarely damaged.

Problems with the mixing valve are often caused by cold or hot water passages blocked by small rocks or other tangible objects in the water.

The specific repair steps are:

1. Turn off the main water valve;

2. Remove the logo under the handle of the mixing valve (in fact, it is a decorative cap on the outside of the fixing screw), unscrew the fixing screw, and remove the handle; 3. Unscrew the big screw that fixes the valve core (you need to use a wrench to increase a little force) and remove the valve core;

4. Observe the hot and cold water channel and the mixing channel, which one has dirty stuff in it, and try to pull it out with a wire or other tools;

5. You can use a towel to cover the water outlet, slowly open the cold water channel and hot water channel, observe whether the water flow is smooth, and if the problem has been solved, you can reinstall the valve.

In the process of doing research on kitchen appliance hygiene, I have become a senior maintenance worker, hehe.

The lower part of the handle is generally the one marked with hot and cold water, which can be cut off, and the inside is the hexagon screw, which can be replaced by removing the ball valve, if the valve is really broken, it can be done like this, it may also be that the hot water is blocked, there is no water, you can check it.
