Novel gas-liquid dual-purpose high-frequency rotary valve

Abstract

The invention discloses a novel gas-liquid dual-purpose high-frequency rotary valve. The novel gas-liquid dual-purpose high-frequency rotary valve comprises a base, a valve element fixedly arranged onthe base and a valve sleeve arranged on the valve element in a matched mode. The two side faces of the base are provided with a high-pressure cavity and a low-pressure cavity correspondingly. The upper plane of the base is provided with a first high-pressure gas-liquid channel communicating with the high-pressure cavity and a first low-pressure gas-liquid channel communicating with the low-pressure cavity. The bottom of the valve element is provided with a second high-pressure gas-liquid channel corresponding to the first high-pressure gas-liquid channel and a second low-pressure gas-liquid channel corresponding to the first low-pressure gas-liquid channel. The outer wall of the valve element is provided with a first tangent plane and a second tangent plane. The novel gas-liquid dual-purpose high-frequency rotary valve has the beneficial effects that a transition valve element structure is designed, first through holes and second through holes are formed in the transition valve element, a sealing mold cavity is formed between the valve sleeve and the transition valve element, a sealing cavity is formed between the transition valve element and the valve element, high and low channels and a low-pressure loop communicate in an intersecting mode, and then the high-frequency reversing function is achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical parts, in particular to a novel gas-liquid dual-purpose high-frequency rotary valve. Background technique [0002] The combination test of excitation and other processing equipment is an important test in the field of modern processing and production technology.

Problems solved by technology

However, it has been proved by practice that when the reversing frequency of the rotary valve spool exceeds 6000HZ, the spool will heat up and deform severely, resulting in the phenomenon of being stuck and broken with the valve sleeve.

Moreover, due to the grooves on the valve core and the high precision requirements, the manufacturing difficulty and exchange cost are greatly increased. Therefore, a "new gas-liquid dual-purpose high-frequency rotary valve" is proposed to overcome such problems.
