More toilets, there will always be such a problem, the toilet inlet valve is more than a common toilet failure. But there are still many people who are confused about this, so today Xiaobian addition to give you an analysis of the principle of the toilet inlet valve , but also to discuss with you about the toilet inlet valve should not be how to check the water, how to solve the toilet into the water The valve does not stop water. 
Toilet inlet valve principle
The figure below is the picture of the inlet valve, of course, there are different styles, but most of the principles are similar. . We can see that there are some threads above the inlet pipe that are used to adjust the height, because the height of each toilet is not the same, first rotate it, then push it up to adjust the height, Then everyone did not see the blue box, which is used to close and open the water, it with the rocker to achieve water or water. 
When water comes in, because the water level has not yet reached the height of demand, it is always in the state of water. When the water is full (it can be adjusted when the required height is reached), the water flows into the blue box in the figure above. Because the wind box is installed upside down, when the water has a certain buoyancy, there is A force online push to achieve the control of the joystick principle (you can do some experiments, take a cup, and put it upside down to the water, look to see if it is necessary to force, and no matter how put will float) is this Principle. 
How to do toilet water inlet valve, check the reason
1. Check whether the buoyant cargo float of the inlet valve is stuck. You can pull the buoy (float ball) up and down by hand. Generally, it can move up and down smoothly.
2. Check that there may be foreign matter inside the inlet valve, resulting in that the needle valve pressure chamber at the top of the inlet valve cannot be formed so that it cannot stop water. In such a situation, it is very difficult for the average user to repair it alone. Please ask a professional to repair or purchase a replacement.
3, check the inlet valve float bucket is stuck or interference. Normally, floats are free to move up and down.
4, check its own internal water valve problems, such as the inlet valve body into the sand or small debris. Like this kind of problem, you can only buy one again and change it. More difficult to repair. 
Toilet water valve is not water how to do two solutions
1. Close the water inlet angle valve and remove the water stop cap from the falling water area. Check if it is deformed, aged, or has foreign matter stuck. Then clean or replace the water stop flap.
2. Close the inlet angle valve and remove the broken special nut with a Phillips screwdriver. Replace the new shaped nut and tighten it.
3, close the inlet angle valve. Put the water in the tank below the water outlet. After adding the dark solution to the remaining water, observe whether there is any water leakage at the flushing port. Yes, it is confirmed that the porcelain body is cracked; if not, the triangle valve is slowly opened. Place the water on the top of the water inlet and above the flap of the water stop. Check for leaks at the same time when entering the water. When the water is placed on the level of the body lip, if the water is released from the lip surface, it is confirmed that the body is cracked.
4, regular cleaning. Regular cleaning of the inlet valve can also reduce the occurrence of more than water. Remove the water inlet pipe from the bottom left of the toilet bowl, and then remove the plastic nut at the bottom of the inlet valve. If there is anything like a filter, please remove it together. Then you can take the inlet valve out of the tank. Remove the fill valve of the inlet valve. Take the plastic cover. Drift the connecting rod to loosen it. Then turn it upside down with the force in the opposite direction. Open the inside of the needle pad and clean it. Then reinstall it. All right.
How to remove the toilet inlet valve
1, we must first check the old toilet there is no crack, pay special attention to the place to start raising the toilet, because the toilet is made of ceramics, like a glass will cut people, so wear a thick work when moving the toilet gloves.
2. Then lift the lid of the tank—disassemble the lid of the tank and take the lid to a place it will not touch.
3, also need to turn off the water, the water valve is located on the left side of the toilet.
4. Then flush the water out of the water tank, do not put on the water flushing handle, let the water flow completely and put on rubber gloves. Use a sponge or a towel to dry the water that has not run out in the tank. 
5. The remaining water in the toilet can be emptied with a small disposable container. Use a sponge or towel to dry the rest of the toilet water.
6. Remove the connected hose from the toilet and pour excess water into the bucket.
7. Let the tank and toilet seat connect. The bolt may not be removed. Removing the tank from the toilet seat can sometimes take several hours.
8. Remove the nuts and bolts for fixing. Sometimes the bolt will turn, so use a hacksaw to saw the bolt broken. You can buy a single-handle saw for use in work spaces where space is at a premium. If the toilet tank leaks and opens the toilet tank, let's see what level the water scoop is inside when the tank is full. If the internal water is full and the tank is still flooding, then surely it will leak out. 
The above is related to how the toilet inlet valve is not limited to water and the principle of the toilet inlet valve . I hope to help you. If there is anything you don't understand, you can follow our website. We will share exciting content regularly.
