specific Embodiment approach

[0016] The evaporator valve includes a rectangular box-shaped shell 1, and round tube-shaped support tubes 3 are vertically arranged on both sides of the shell 1, and a round tube-shaped flexible tube 2 is fixed inside the two support tubes 3 and the shell 1. 1. The top is vertically inlaid with a round pipe-shaped threaded pipe 8. The threaded pipe 8 is tapped with concave threads. The threaded pipe 8 is equipped with a threaded rod 6 that is threaded with each other. The threaded rod 6 is located on the outer end of the shell 1. One end of the threaded rod 6 located inside the housing 1 is vertically provided with a pressing plate 4, and the pressing plate 4 protrudes in a quarter-circle arc shape toward the side of the flexible pipe 2, and a quarter-circle is provided at the center of the bottom of the inner wall of the housing 1. A round arc-shaped locking sleeve 5, the concave surface of the locking sleeve 5 faces the flexible pipe 2, the concave surface of the locking sle...

Abstract

The invention relates to the field of mechanical equipment, and provides a leak-proof evaporator valve comprising a rectangular box-shaped shell. The both sides of the shell are vertically provided with cylindrical support pipes, and the two support pipes and the shell are internally provided with cylindrical flexible pipes fixedly; the top of the shell is vertically provided with a cylindrical threaded pipe in an inlaid manner, and concave threads are tapped in the threaded pipe; the threaded pipe is internally provided with a threaded rod in a screw-thread fit mode, and the end, located at the exterior of the shell, of the threaded rod is provided with a rotary handle; the end, located in the shell, of the threaded rod is vertically provided with a pressing plate, and the side, facing the flexible pipe, of the pressing plate protrudes in an arc shape; an arc-shaped locking sleeve is arranged at the relative position between the bottom of the inner wall of the shell and the arc-shapedprotrusion of the pressing plate; and the concave surface of the locking sleeve faces the flexible pipe, and the locking sleeve and the pressing plate are in clearance fit with each other. The leak-proof evaporator valve is ingenious in design and excellent in sealing performance; and the leak-proof evaporator valve does not leak after being used for a long time, and the service life is long.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to an anti-leakage evaporator valve. Background technique [0002] The evaporator is a very important part of the four major components of refrigeration. The low-temperature condensed liquid passes through the evaporator, exchanges heat with the outside air, vaporizes and absorbs heat, and achieves the effect of refrigeration. There are many valves installed on the evaporator to control different pipelines. The existing valves for evaporators are relatively traditional in design, resulting in a significant decrease in the tightness of the closure after they have been used for a long time, so that liquid leakage occurs in the evaporator, which will affect the normal use of the evaporator. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned prior art, and provide a leak-proof evaporator valve, which has a...
