Example one

As shown in fig. 1, the utility model relates to a multifunctional three-way valve, including valve body 1 and the valve slot 2 of setting in valve body 1, the inside of valve body 1 still is provided with inlet opening 12 and diffluence opening 5, the outside and the inlet tube 13 intercommunication of inlet opening 12, the outside and the outlet pipe 6 intercommunication of diffluence opening 5. Water enters through the water inlet pipe 13, then is shunted through the valve body 1, and respectively flows out of the water outlet pipe 6.

Further, an ear plate 10 for valve fixing is integrally mounted on the exterior of the valve body 1.

Furthermore, the number of the flow distribution holes 5 is two, the flow distribution holes 5 are symmetrically distributed on two sides of the valve body 1 along the valve slot 2, and a filter plate 4 is installed in each flow distribution hole 5.

Further, the pipe orifices of the water inlet pipe 13 and the water outlet pipe 6 are both arranged in a flange connection pipe structure.

As shown in fig. 1, a pressure spring 3 is installed in the valve slot 2, a choke block 9 is connected above the pressure spring 3, and movable filter plates 4 are installed on the valve slot wall plates at two sides of the pressure spring 3, so that liquid can be prevented from returning and a certain filtering function can be realized.

The internal integrated type of the valve spool 2 is provided with a check ring 7 for preventing the choke block from excessively moving downwards, the choke block 9 above the check ring 7 is in clearance fit connection with the valve spool 2, and the end parts of the choke block 9 and the water inlet hole 12 are in movable fit connection. When the flow blocking block 9 is in a natural state, the end part of the water inlet hole 12 is abutted to realize the internal sealing of the water inlet hole. When water flow in the water inlet hole 12 impacts the flow blocking block, the flow blocking block 9 moves downwards, and the check ring 7 is used for preventing the flow blocking block from excessively moving downwards to damage the pressure spring.

Further, a plating layer 11 is electroplated above the choke block 9, and the plating layer is a corrosion-resistant layer.

Preferably, the coating 11 in this embodiment is a zinc-nickel alloy coating structure, which is effective in corrosion resistance.
