Stop valve for air conditioner

Abstract

The invention discloses a stop valve for an air conditioner. The stop valve comprises a valve body with a joint hole and a valve core, wherein the valve core comprises a valve rod and a piston arranged on the end part of the valve rod, a valve cap is arranged on a main hole port of the valve body, and the valve cap forms a through hole with an inner thread; and the through hole and an external thread arranged outside the valve rod realize vertical rotating flexible connection, and a cone hole is formed in a position on the joint hole, which approaches to the inner end part of the valve body. The stop valve provided by the invention can realize the communicated use of a high pressure stop valve and a low voltage stop valve, the whole structure is compact, the operation is convenient, the manufacturing cost can be saved, the installation space is reduced, the installation and maintenance programs are simplified, a person can operate conveniently, meanwhile, the production and manufacturing cost and difficulty are reduced, the energy consumption is reduced to a certain extent, and an energy conservation and emission reduction effect is achieved.

Description

technical field [0001] [0002] The invention relates to a cut-off valve for an air conditioner. [0003] Background technique [0004] [0005] At present, in the market, the high-pressure globe valve and the low-pressure globe valve we have seen have different structures, and the valve body and the valve stem cannot be used in conjunction with each other, so there is a lot of inconvenience in use, such as installation, Wait on maintenance. [0006] low pressure shut-off valve figure 1 As shown, on both sides of the valve body 1: there is a joint hole 2 on one side, and a valve core hole 3 on the other side. This structure not only leads to a larger installation space occupied by the globe valve, but also increases the installation process. The complexity of the operation will reduce the efficiency of installation, and there are also problems such as large consumption of copper materials, high production costs, and complicated manufacturing processes! [0007] In addi...

AI Technical Summary

Problems solved by technology

[0008] As shown in the current high-pressure stop valve, in the actual use process, the valve stem on the stop valve passes through the snap ring groove on it, as well as the groove on the inner wall and the combination of the rigid snap ring placed in the groove to prevent the valve core from being damaged by the debugger. Misoperation causes the valve core to shoot out under the pressure inside the system when it is over-exited, resulting in seal failure and injury accidents

Such a structure is complex and has many deficiencies

Not only the manufacturing and assembly process is complicated, but also the adjustment and maintenance during use are also complicated, and there are dangers

If the adjustment or installation is not in place, the parts on the stop valve will rebound on the person, and accidents will occur, which needs to be improved!
