Electromagnetic operation valve with multi-section combined valve element structure

Abstract

The invention discloses an electromagnetic operation valve with a multi-section combined valve element structure. The electromagnetic operation valve comprises multiple sections of combined valve elements and mated valve bodies; the valve elements comprise at least three sections of valve element bodies and mated skeletons; according to the structural form of the valve elements, the valve elementbodies and the mated skeletons are assembled in sequence and then arranged in the mated valve bodies; the outer sides of the skeletons and the inner walls of the valve bodies are tightly connected; and convex surfaces of the inner sides of the skeletons and the valve element bodies are in float sealing connection. Through float sealing connection between the valve element bodies and the skeletons,the maximum flows between the valve element bodies and the skeletons can be guaranteed in the shortest displacement travels of the valve element bodies, so that the reaction speed and the acting frequency of the electromagnetic operation valve in effective time are greatly improved, the friction between sealing pieces and the skeletons is prevented, and the service life of the electromagnetic operation valve is prolonged; and as the valve elements are designed as a combined structure, the valve element bodies with a corresponding number and the mated skeletons are added as needed to achieve the expansion application of the electromagnetic operation valve.

Description

technical field [0001] The invention relates to the technical field of electromagnetic operation valve equipment, in particular to an electromagnetic operation valve with a multi-section combinable valve core structure. Background technique [0002] The spool of the existing electromagnetic operation valve is an integral structure, such as figure 1 As shown, the valve core and the inner wall of the valve body are sealed and connected by a seal. When gas exchange is required, the gas exchange can only occur when the valve core slides until the seal is not in contact with the inner wall of the valve body. In this way, the valve The stroke of the core is very long, so the reaction speed and action frequency are relatively slow within the effective time, and after the seal and the valve body are in contact for a long time, the seal is easy to wear, which will directly affect the life of the electromagnetic operation valve. In addition, When a small solenoid-operated valve is ne...

[0002] The spool of the existing electromagnetic operation valve is an integral structure, such as figure 1 As shown, the valve core and the inner wall of the valve body are sealed and connected by a seal. When gas exchange is required, the gas exchange can only occur when the valve core slides until the seal is not in contact with the inner wall of the valve body. In this way, the valve The stroke of the core is very long, so the reaction speed and action frequency are relatively slow within the effective time, and after the seal and the valve body are in contact for a long time, the seal is easy to wear, which will directly affect the life of the electromagnetic operation valve. In addition, When a small solenoid-operated valve is required, because the inner hole of the valve is very small, hooking and groove processing cannot be performed, and miniaturization cannot be realized, which limits the use and popularization of the solenoid-operated valve
