When the faucet 11 turns on its switch to allow water to flow through the middle pipe 12 to its end, the initial pressure of the water is not enough to push the block. The gasket 25 and the plug 32 of the valve stem 32 of the port 311, so the initial effluent remains in the faucet 11. After the faucet 11 is turned on, the old water in the original faucet 11 and the new water opened will have enough time to mix. Until the pressure of the water is sufficient, the plug 32 of the valve rod 32 can be pushed down axially, so that the plug portion 322 compresses the spring 33, and the valve rod 32 moves axially downward to form the plug portion 322 retracted from the through port 311, so that water flows from the middle pipe. 12. The gasket 25 and the opening 311 are sent through the inner slot 314, the flow hole 313, the square bolt groove 231 of the bottom ring 23, and the anti-cockroach mesh 22 out of the water outlet 21 of the water outlet 21 for use. Otherwise, the faucet 11 When the switch is closed, the water pressure is reduced, and the valve stem 32 pushes the plug portion 322 axially upward by the elastic restoring force of the spring 33 to re-block the flow port of the through port 311. In this way, the water pressure valve 30 makes the Stay in the dragon without turning on the water The old water in the head 11 and the fresh water after opening have time to mix. After the water pressure reaches the set value, the position of the valve stem 32 of the water pressure valve 30 can be retracted to form a water outlet space to make water flow out. 11 The quality of the effluent is better than before.
