The plunger type water purification valve is mainly composed of a valve body, a valve cover, a plunger and a valve seat. The plunger is installed inside the valve body and controls the flow of the fluid by rotating.

[0010] Most existing water purification valves need to be equipped with an upper collector-distributor connection sleeve that is assembled on the valve body by screws to connect with the upper collector-distributor, which is troublesome to assemble and increases the cost of parts.
