Adjustable temperature control valve

Abstract

The invention discloses an adjustable temperature control valve which comprises a valve body. The middle of one end of the valve body is connected with a cylindrical heating element, an expansion control sleeve is sleeved on the radial circumferential surface of the heating element, an inner hole of the expansion control sleeve is adaptive to the outer diameter of the heating element, more than three radial bolt through holes are uniformly distributed along the circumferential direction of the expansion control sleeve, and an adjusting bolt is arranged in each bolt through hole. The adjustable temperature control valve is simple in structure and convenient to manufacture and use, normal working life of the temperature control valve can be prolonged greatly as compared with that in the past, failure rate of shutdown caused by rising of oil temperature is decreased, maintenance frequency is reduced, and maintenance and replacement workload and corresponding labor and component cost are reduced.

Description

technical field [0001] The invention relates to the technical field of air compressor lubrication, in particular to an oil temperature control valve. Background technique [0002] In screw air compressors, ideal oil temperature control is a necessary condition to ensure the normal operation of the unit. The oil temperature control valve (hereinafter referred to as "temperature control valve") includes a valve body, and a thermal element is connected to the valve body. When in use, the temperature control valve is installed on the oil pipeline. When the lubricating oil flows through the thermal element of the temperature control valve, the opening amount of the valve is automatically adjusted by the oil temperature value (the thermal element stretches longer when the oil temperature is high, and the oil When the temperature is low, the thermodynamic element shrinks shorter, thereby automatically adjusting the position of the valve body), so as to control the cooling amount o...

AI Technical Summary

Problems solved by technology

When the thermal element is damaged, it will cause the compressor to be overcooled or overheated and cause shutdown

In the actual use process, the thermal element of the temperature control valve is prone to fatigue damage due to long-term work, resulting in insufficient expansion of the thermal element, resulting in insufficient or no stretching of the valve core, affecting the opening amount of the valve, resulting in failure of the temperature control valve and adjustment deviation. increase, failure

In the past, after this situation occurred, it was necessary to replace the new temperature control valve, which was costly and inconvenient to maintain.
