Abstract

The invention discloses a stop valve and an air conditioner with the stop valve. The stop valve comprises a valve seat, a lantern ring, a valve spool and an elastic sealing element, wherein a valve chamber and a fitting chamber communicated with the valve chamber are defined in the valve seat, the fitting chamber is located on the first end surface of the valve chamber and the valve chamber is further provided with two openings communicated therewith; the lantern ring internally sleeves one opening; the valve spool comprises a fitting part and a stop part arranged on the fitting part, the fitting part in in threaded fit with the fitting chamber, the stop part is located in the valve chamber and is in threaded fit with the valve chamber, and the stop part is in contact with the first end surface of the lantern ring to connect/disconnect the two openings; the elastic sealing element is arranged on the end surface, towards the lantern ring, of the stop part, and the elastic sealing element is in contact with the end surface of the lantern ring to disconnect the two openings. The stop valve disclosed by the invention has the advantages that the locking torque is reduced to a certain extent, the wear of the sealing surface between the lantern ring and the valve spool is avoided, the internal leakage of the stop valve is avoided, the service life of the stop valve is prolonged and the maintenance rate of the stop valve is reduced.

Description

technical field [0001] The invention relates to the field of mechanical equipment manufacturing, in particular to a shut-off valve and an air conditioner with the same. Background technique [0002] Generally, the spool and collar of the stop valve are made of metal. When the stop valve is in the cut-off state, in order to make the sealing surface between the spool and the collar have good sealing performance, a larger locking force is generally used. However, a large locking torque is likely to cause wear on the sealing surface between the valve core and the collar, resulting in internal leakage of the globe valve. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the present invention proposes a shut-off valve, which can reduce the locking torque at least to a certain extent, avoid wear of the sealing surface between the collar and the valve core, and thereby a...
