Four-channel reversing plunger valve

Abstract

The invention discloses a four-channel reversing plunger valve which comprises a valve body and a plunger body. The four-channel reversing plunger valve is characterized in that the valve body is in across-shaped four-way structure; the valve body consists of a first channel, a second channel, a third channel, a fourth channel and a cylinder body; the first channel, the second channel, the thirdchannel and the fourth channel are uniformly arranged along the periphery of the cylinder body; the plunger body is in a cylinder structure; the plunger body is provided with a first U-shaped channeland a second U-shaped channel in the radial direction; the first U-shaped channel does not communicate with the second U-shaped channel; the plunger body is arranged in the cylinder body; and channelports of the first U-shaped channel and the second U-shaped channel communicate with the first channel, the second channel, the third channel and the fourth channel correspondingly. The communicationdirections of the four-channel reversing plunger valve can be switched simply by rotating a hand wheel by 90 degrees, and various different pipeline communication modes are realized.

Description

technical field [0001] The invention relates to the valve field of food and beverage filling technology, in particular to a four-channel reversing 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 support for valve production and R&D, domesti...

AI Technical Summary

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 the flow directions of the four channels to achieve simultaneous connection and simultaneous closure.
