Problems solved by technology

[0008] The existing four-way valves can only be connected in twos and cut off in twos, but cannot realize the mutual conversion of four-channels and three-way to achieve simultaneous connection and simultaneous closure.
Moreover, the existing four-way valve cannot self-adjust the flow rate and cannot automatically shut off when backflow occurs.

Abstract

The invention discloses a four-channel three-way reversing and automatic return plunger valve, which comprises a valve body, a plunger body and a valve bottom plate. The valve body is a cross-shaped four-way structure. The second channel, the third channel, the fourth channel and the cylinder body are composed of a T-shaped channel in the radial direction of the plunger body. The plunger body is set in the cylinder body. An accommodation space is provided between the cylindrical guide sleeve, the plunger body and the valve bottom plate, and the valve passages communicate with the accommodation space through feedback pipelines. In the present invention, a feedback pipeline is provided on the valve body. The feedback pipeline can automatically adjust the flow rate and pressure of the valve according to the pressure and flow of the fluid at the valve inlet. The feedback pipeline can automatically close the valve when the fluid backflow is detected at the valve outlet, so as to achieve the function of backstop. .

Description

technical field [0001] The invention relates to the technical field of valves for food and beverage filling technology, in particular to a four-channel three-way reversing and automatic return plunger valve. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve and so on. [0003] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of varieties and specifications. [0004] In terms of technical...
