Description

Air conditioner stop valve and air conditioner

Technical Field

The utility model relates to an air conditioning equipment technical field particularly, relates to an air conditioner stop valve and air conditioner.

Background

Currently, air conditioners on the market generally use a shut-off valve to prevent leakage of refrigerant, and existing air conditioner shut-off valves, the valve core and the valve body are generally sealed by a rubber sealing ring, and the valve core and the valve body are sealed by the rubber sealing ring when the stop valve is closed or opened, the rubber sealing ring is easy to cause the sealing failure due to fatigue and aging in the long-term working process, therefore, the valve bonnet is usually installed outside the valve body of the stop valve, the valve bonnet and the valve body are generally fixedly sealed through threads, double sealing is realized through a rubber sealing ring inside the valve body and the valve bonnet outside the valve body, however, the sealing mode has certain defects, on one hand, the valve cap and the valve body are sealed through threads, so that the production and processing cost is increased, the production and assembly efficiency is reduced, and on the other hand, the thread sealing effect is poor.

Some stop valves that utilize the contact surface on the case, contact with the contact surface of valve body inside and seal have also appeared on the market now, but this kind of stop valve also has certain defect, and the sealed face of its case and valve body contact is located the middle part of valve body, is unfavorable for the location of case and the sealed face of valve body, especially when the inside high pressure medium that is of valve body, sealed face dislocation can appear for a long time using, and then leads to the not tight problem of sealing.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing an air conditioner stop valve and air conditioner to solve among the prior art problem that the sealed effect of air conditioner stop valve is poor, with high costs, packaging efficiency is low.

In order to achieve the above purpose, the technical scheme of the utility model is realized like this:

an air conditioner shut-off valve comprising: the valve comprises a valve body and a valve core, wherein a first inner cavity and a second inner cavity are arranged on the valve body, the valve core can move in the first inner cavity to switch the first inner cavity and the second inner cavity, a stop part is arranged at one end of the valve body, a third contact surface is arranged on the stop part, one end, close to the stop part, of the valve core is a valve core head part, a first contact surface is arranged on the valve core head part, and the first contact surface and the third contact surface can be in contact sealing.

This application air conditioner stop valve is through set up first contact surface on the valve core head set up the third contact surface on the stop part, work as when the case moves stop part one end, first contact surface on the valve core head can contact with the third contact surface on the stop part and seal, form the face and seal, because the valve body is inside to be high pressure medium, the valve core head under high pressure medium's effect, with stop part in close contact with, further strengthened the sealed effect of the sealed face that first contact surface and third contact surface formed, and this kind of sealing mode simple structure sealing performance is stable, and production and processing is convenient.

Further, the contact sealing surface of the first contact surface and the third contact surface is a conical sealing surface.

This application among the air conditioner stop valve, adopt the sealed face of toper between case and the stop part, seal the inside medium of valve body, on the one hand, the case is under the promotion of the inside high-pressure medium of valve body, and the toper seal structure is fixed a position easily, and is sealed effectual, can not lead to the fact the medium to reveal because of sealed cooperation is not in place, and on the other hand, the sealed effect of the sealed face of toper in high-pressure medium is stable, and is difficult for fatigue wear.
