A Pilot Piston Type Waterway Switching Divider Valve

Abstract

The invention relates to a pilot piston type water way switching shunt valve which comprises a three-way valve body, an electromagnetic valve, a sealing rod and switching assemblies. Each of two water outlets of the three-way valve body is controlled by one switching assembly to be opened and closed. The electromagnetic valve drives the sealing rod to reciprocate and then two gears are arranged. According to one gear, the water pressure of one face towards the corresponding water outlet of a piston inside one switching assembly is larger than that of the other face of the piston inside the switching assembly, then the piston releases the water outlet, the water pressure of one face towards the corresponding water outlet of a piston inside the other switching assembly is smaller than that of the other face, and then the piston closes the water outlet. According to the other gear, the water outlet in the released state originally is closed, and the water outlet in the closed state originally is released. The two water ways can be controlled to be opened or closed only by adopting one electromagnetic valve, the function is achieved in a one-open and one-closed mode, the requirement for controlling existing shower heads and showers is met, the structure is simple, the requirement for space is small, and the better advantage is provided for the ultrathin appearance of the product.

Description

technical field [0001] The invention relates to a water separator, more specifically, to a pilot piston type water channel switching water diversion valve. Background technique [0002] With the intelligentization of the shower system in the bathroom industry and the continuous development of automation, in order to realize the automatic control of the switching and opening and closing of the waterway, it is generally realized through a pulse type solenoid valve control. [0003] But the current pulse solenoid valve can only realize the opening and closing function of one solenoid valve to control the opening and closing of one waterway, and cannot realize the opening and closing of two waterways controlled by one solenoid valve; its function has the following defects: [0004] 1. From the perspective of energy saving and environmental protection, when a shower system needs to control two or more waterways, it needs to use two or more solenoid valves to control, which will w...

AI Technical Summary

Problems solved by technology

[0003] But the current pulse solenoid valve can only realize the opening and closing function of one solenoid valve to control the opening and closing of one waterway, and cannot realize the opening and closing of two waterways controlled by one solenoid valve; its function has the following defects:

[0004] 1. From the perspective of energy saving and environmental protection, when a shower system needs to control two or more waterways, it needs to use two or more solenoid valves to control, which will waste a lot of electric energy. If The use of hydropower for power supply will affect the insufficient power supply and cannot achieve normal operation;

[0005] 2. The end face sealing method of plugging small holes in the prior art needs to apply continuous holding force;

[0006] 3. A solenoid valve controlling a waterway will have an overlapping relationship with the space, and there is no advantage in space utilization;

[0007] 4. Higher cost
