T-shaped three-channel reversing and automatic non-return plunger valve

Abstract

The invention discloses a T-shaped three-channel reversing and automatic non-return plunger valve. The T-shaped three-channel reversing and automatic non-return plunger valve comprises a valve body, aplunger body and a valve bottom plate; the valve body is of a T-shaped tee-joint structure, the valve body is composed of a first channel, a second channel, a third channel and a cylinder body, the plunger body is of a cylindrical structure, a T-shaped channel is formed in the radial direction of the plunger body, channel openings of T-shaped channel of the plunger body aer communicated with anythree or two channels of the first channel, the second channel and the third channel, the valve bottom plate is fixedly mounted at the bottom of the valve body, a cylindrical guide sleeve is arrangedon the top of the valve bottom plate, a bearing rod is arranged at one end of the plunger body, the bearing rod is sleeved with the guide sleeve, a containing space is arranged between the plunger andthe valve bottom plate, and the first channel, the second channel and the third channel are communicated with the containing space through feedback pipelines. The communication manner of a tee-jointor two-way multifunctional valve can be achieved by rotating different stations of the plunger body and the valve body.

Description

technical field [0001] The invention relates to the technical field of valves for food and beverage filling technology, in particular to a T-shaped three-channel reversing and automatic check 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 ...

AI Technical Summary

Problems solved by technology

[0008] Existing valves can only realize the flow rate of the valve through external control and adjustment, and cannot realize the defect that the valve can adjust the flow rate adaptively according to the flow rate
