Problems solved by technology

The technical difficulty of the electric control valve lies in the stability and sensitivity of the vacuum bellows. Due to the excessive compression compensation of the bellows, the electric control valve cannot be closed when the V number specified by the electric control valve needs to be closed. The compression compensation of the bellows is too large. The small size leads to the electric control valve closing too fast, which is easy to change the shape of the bellows, and the current electric control valve bellows on the market have low sensitivity and are greatly affected by the environment

Abstract

The invention aims to provide a corrugated pipe for an electric control valve. The corrugated pipe comprises an upper end cover, a corrugated pipe body, a built-in spring and a lower end cover; the corrugated pipe is characterized in that the upper end cover and the lower end cover are arranged at the upper end and the lower end of the corrugated pipe body in a sleeved mode respectively, the built-in spring is connected with the upper end cover and the lower end cover, and the corrugated pipe body is machined and formed according to the same wall thickness wave height ratio; The elasticity of the corrugated pipe is increased, the shrinkage proportion of the corrugated pipe is favorably compensated, the compression proportion of unit compression force is improved, the adjusting capacity of the corrugated pipe is improved, and the utilization requirements in different environments are met.

Description

technical field [0001] The invention relates to the field of bellows, in particular to an electric control valve bellows. Background technique [0002] The electric control valve in the compressor of the air conditioner usually uses bellows as the pressure-sensitive element. The coil is energized to generate electromagnetic force, the moving iron core is magnetized and moves to the static iron core, the bellows is compressed by the compression force, and the valve formed by the valve core and the body starts adjust. The technical difficulty of the electric control valve lies in the stability and sensitivity of the vacuum bellows. Due to the excessive compression compensation of the bellows, the electric control valve cannot be closed when the V number specified by the electric control valve needs to be closed. The compression compensation of the bellows is too large. The small size causes the electric control valve to close too quickly, which is easy to change the shape of ...
