The operating principle of the pilot diaphragm float valve is as follows: when the water level is low and the valve supplies water from the inlet end, the stop rod 51 is separated from the diaphragm 3 without sealing, water flows through the throttling hole 31 in the diaphragm 3 to enter the diaphragm cavity 21, the water in the diaphragm cavity 21 flows out from the pilot valve core mounting hole through the pilot cavity 22, the left pressure and the right pressure of the diaphragm are balanced, the valve is in a fully open state, and water is supplied to a water tower (pool). When the water level rises and reaches a certain height, the floating ball 66 moves upwards, the micro connecting rod 52 moves leftwards through the lever, the stop rod 51 is tightly contacted and sealed with the diaphragm 3, the water in the diaphragm cavity 21 cannot be discharged, the pressure of the diaphragm cavity rises, the diaphragm 3 is pushed to be contacted with the valve seat 14 on the valve body 1, the valve is closed, and the water supply of a water tower (pool) is stopped. When the water level of the pool descends, the floating ball 66 moves downwards, the micro connecting rod 52 moves rightwards through the lever, the stop rod 51 is separated from the diaphragm 3, water in the diaphragm cavity 21 flows out through the pilot cavity 22, the pressure in the diaphragm cavity 21 is reduced, the diaphragm moves rightwards to be separated from the valve seat on the valve body, and the valve is opened again to continue water supply.
The above is only the preferred embodiment of the present invention, and all the equivalent changes and modifications made according to the claims of the present invention should be covered by the present invention.
