The toilet in your house leaks, which makes the toilet unable to enter, or your water meter goes up a lot of circles. How to improve the toilet leakage? Let's have a look!
Because the metal upper guide rod straight down water sealing rubber valve is rigidly connected with the valve, and the guide rod is connected with the handle take-up; when the rotating handle is opened, the take-up rod and the upper guide rod will make circular arc movement, and the radial movement of the guide rod is limited in the guide bracket, which causes the metal guide rod to be pulled, bent and deformed, causing the guide rod to be stuck on the guide bracket, and the rubber valve will not fall down or bend, slide and deviate Fall on the drain valve port, resulting in improper reset, failure to seal and water leakage.
Of course, the sealing cover of the drain valve and the sealing surface of the valve body are not closely matched, which also causes water leakage of the toilet. There are two types of seal: wire contact seal and face contact (plane or curved surface) seal. The traditional flap seal valve cover mostly belongs to line contact seal. From the inspection, the main reason for the water leakage of the drain valve itself is the improper selection of the flap material, the deformation of the flap itself or the process defect of misplacing the sealing surface of the valve body after the use of the flap under pressure in the water. The sealing performance of the drain valve with face contact seal is better than that of the drain valve with line contact seal.
The connection of drain valve is not sealed tightly. Because the joint of non disposable drainage valve is not sealed tightly, under the action of water pressure, water flows into the toilet through the overflow pipe from the interface gap. How can the decoration save money? Install the net at home, and design the budget quotation free of charge. Cause water leakage. The lift type water inlet valve which can change the height freely, if its sealing ring does not fit closely with the pipe wall, water leakage will often occur.
The above is the cause of toilet leakage. After finding out the cause, of course, it is necessary to transform the toilet in time. There are two ways to transform the toilet leakage, i.e. leakage control valve and flexible water-saving valve.
I. leakage control principle of leakage control valve
It uses the flexible sling to lift the position, the valve body is positioned and turned over, and relies on the instantaneous siphon effect of the drain port on the rubber valve spherical surface and the pressure of the water supplement volume of the water tank on the rubber valve, so as to realize the accurate sealing of the drain port of the rubber valve and the leakage elimination effect.
II. Leakage control principle of flexible water-saving valve
The flexible valve is lifted by flexible sling, the valve body is positioned and turned over at the water inlet, and the incompressibility, fluidity and plasticity of the liquid are scientifically utilized to achieve the leakage compensation effect with the free deformation of the rubber film.
