Document Type and Number:
WIPO Patent Application WO/2022/127400
Kind Code:

Abstract:
A stop valve (100) and an air conditioning system comprising the stop valve (100). The stop valve (100) comprises a valve body (10) and a valve core (20), wherein the valve body (10) has a first opening (11), a second opening (12) and a valve cavity (13); the valve body (10) is further provided with a filling end (14); and an extension line of a second axis (121) intersects a first axis (111) at a first intersection point (1211), an extension line of a third axis (141) intersects the first axis (111) at a second intersection point (1212), which satisfies the following relational expression: d1 < d2, where d1 is the distance from the first intersection point (1211) to the first opening (11), and d2 is the distance from the second intersection point (1212) to the first opening (11). By means of the stop valve, a fluid flows more smoothly in the valve cavity, and the flow channel turns relatively smoothly, which can effectively reduce the pressure loss.
