Electromagnetic expansion valve with noise reduction mechanism

Abstract

The invention discloses an electromagnetic expansion valve with a noise reduction mechanism, which comprises an electromagnetic expansion valve body, wherein the right side of the electromagnetic expansion valve body is communicated with an air spraying pipe, the right side of the air spraying pipe is slidably connected with a corrugated sleeve, the right side of the corrugated sleeve is fixedly connected with a threaded sleeve, a guide screen pipe is fixedly installed on the surface of the air spraying pipe through the threaded sleeve, the surface of the guide screen pipe is fixedly connected with a micropore sleeve, and the bottom of the left side of the micropore sleeve is communicated with a micropore pipe. According to the invention, noise generated by the electromagnetic expansion valve body is subjected to noise reduction treatment through the microporous sleeve by the guide screen pipe, then noise sound waves are reflected for multiple times to generate friction by the microporous pipe and the silencing pipe through a blocking silencing plate and a spiral screen piece, and then sound energy of the noise is converted into heat energy to be dissipated, so that the electromagnetic expansion valve has the advantage of being capable of effectively reducing the noise, and the problem that in the using process of an existing electromagnetic expansion valve, when wet steam is sprayed out of a valve body, large spraying noise can be generated is solved.

Description

technical field [0001] The invention relates to the technical field of electromagnetic expansion valves, in particular to an electromagnetic expansion valve with a noise reduction mechanism. Background technique [0002] The expansion valve is an important part in the refrigeration system, which is generally installed between the liquid storage cylinder and the evaporator, and the electromagnetic expansion valve is a common type of expansion valve, but the existing electromagnetic expansion valve is wet during use. When the steam is sprayed out from the valve body, there will be a lot of injection noise, which will affect the use of the user. Contents of the invention [0003] In order to solve the problems raised in the above-mentioned background technology, the object of the present invention is to provide an electromagnetic expansion valve with a noise reduction mechanism, which has the advantage of being able to effectively reduce noise, and solves the problem of wetne...
