[0005] Furthermore, the water inlet bottom spiral connection has a filter pipe, the filter pipe outer wall is fixedly connected with a fixed block, the fixed block inner wall is inserted with a fastening bolt, the filter pipe is internally provided with a filter frame, and the filter frame is internally provided with a filter screen.

[0006] Furthermore, the second sealing ring is arranged between the water inlet and the filter pipe, and the first sealing ring is arranged between the top of the filter frame and the filter pipe.

[0007] Furthermore, the inlet and outlet shell front and back are both fixedly connected with vertical reinforcing ribs.

[0008] Furthermore, the filter frame top and the filter pipe outer wall are both fixedly connected with fixed blocks, and the filter frame top fixed block and the filter pipe outer wall fixed block are arranged in a straight line.

[0009] The one-way switch water supply valve has the beneficial effects that:

[0010] By setting filter frame and filter screen, when the water supply valve is used, the water source entering the water inlet and outlet shell is effectively filtered, the impurities in the water source are prevented from accelerating the damage of the valve core mechanism, the service life of the valve core mechanism is effectively improved, in addition, the filter frame can be quickly disassembled from the filter pipe by disassembling the fastening bolt, the filter screen is cleaned in subsequent use, so that the filter screen is prevented from being blocked after long-time use and affecting subsequent water supply.

[0011] By setting the water drain valve, excess water can be quickly drained from the side of the water inlet and outlet shell, the pressure in the water inlet and outlet shell is effectively relieved, damage is avoided, and the fastening strength during use is effectively improved by setting the reinforcing ribs.
