Problems solved by technology

At present, pipelines are generally used to connect high-pressure refrigeration cylinders and three-way valves. This connection method is complex in operation, complex in structure, bulky, and requires a large assembly space. It can no longer meet the requirements of weapon system assembly layout and replacement convenience. One of the bottlenecks in the development and development of weapon systems

Abstract

The invention relates to a reversing tee valve with a quick connection function. The reversing tee valve comprises a valve assembly, a push rod, two plunger connectors, sleeve nuts and steel balls; the push rod is arranged in the valve assembly; the two plunger connectors are hermetically and fixedly connected to the two ends of the valve assembly respectively; the plunger connectors are providedwith air supply channels, and the push rod can move in the air supply channels of the plunger connectors; the push rod is provided with two air conveying channels, and the two air conveying channels communicate with the air supply channels of the two plunger connectors respectively; the sleeve nuts are connected to the two ends of the valve assembly respectively, and the steel balls are arranged between the sleeve nuts and the valve assembly; and the sleeve nuts are used for being connected with an external high-pressure refrigeration air bottle. The reversing tee valve with the quick connection function meets the requirement for conveniently replacing a refrigeration module.

Description

technical field [0001] The invention relates to a reversing three-way valve, in particular to a reversing three-way valve with a quick connection function. Background technique [0002] With the continuous expansion of the application range of high-pressure refrigerated gas cylinders in the field of infrared refrigeration for weapon systems, higher requirements have been put forward for the reliability of the refrigeration of refrigerated gas cylinders. The redundant configuration of two high-pressure refrigeration cylinders to improve the reliability of refrigeration has become a common form. Two high-pressure refrigerated gas cylinders and a three-way valve form a refrigerated module. When working, the actuator activates one of the high-pressure refrigerated gas cylinders, and the other high-pressure refrigerated gas cylinder is a backup cylinder. The gas in the activated cylinder passes through the three The through valve enters the downstream pipeline to realize the coo...
