AI Technical Summary

Technical Problem

Existing air cooler ball valves suffer from media leakage due to particulate impurities causing scratches on the sealing surfaces of the valve ball and valve body during media transport. The lack of a secondary sealing structure also affects refrigeration efficiency.

Method used

A flexible sealing component and an inflatable positioning component are installed on the valve ball. The flexible sealing component achieves self-adaptive sealing through an annular airbag, and the inflatable positioning component achieves precise positioning and locking through a positioning rod. Combined with a limit sleeve and an adjustment component, the valve ball is ensured to be accurately positioned and easy to operate.

Benefits of technology

It effectively prevents media leakage, ensures the stability and control accuracy of the air cooler system, reduces the operating force of the handle, and extends the service life of the valve.

Abstract

The invention relates to the technical field of ball valves, in particular to an air cooler ball valve which comprises a valve body, a valve ball is rotatably connected to the inner wall of the valve body, a flexible sealing assembly is fixedly connected to the valve ball, a valve rod is fixedly connected to the valve ball, a handle is installed at the top end of the valve rod, and an inflation positioning assembly is fixedly connected to the lower portion of the handle. An adjusting assembly is arranged on the outer wall of the inflation positioning assembly in a sliding fit mode, two limiting sleeves are arranged on the valve body, the flexible sealing assembly is arranged on the valve ball, after the valve ball stops rotating, the adjusting assembly can drive the inflation positioning assembly to automatically inflate an annular air bag in the flexible sealing assembly, the annular air bag is made of a flexible material, and therefore the sealing effect is improved. After being inflated, the valve ball can be tightly attached to the gap between the valve ball and the valve body, self-adaptive sealing is achieved, the sealing reliability is further improved, the problems of unstable system pressure and out-of-control flow caused by medium leakage can be effectively solved, and the operation efficiency of the air cooler is ensured.
