Document Type and Number:
WIPO Patent Application WO/2022/218406
Kind Code:
A1
Abstract:
A control valve (1), comprising a valve body (10), a valve core (20), and a sealing component (41). The control valve (1) comprises communication ports; the communication ports are communicated with a valve cavity (101); the communication ports comprise first communication ports (311); the first communication ports (311) are arranged along the height direction of a side wall portion (11) and the circumferential direction of the side wall portion (11); two first communication ports (311) is arranged on the side wall portion (11) along the circumferential direction of the side wall portion (11); the sealing component (41) comprises a sealing body portion (410); the sealing body portion (410) is located between the valve core (20) and the side wall portion (11); the sealing body portion (410) has through holes (411); the number of the through holes (411) is the same as that of the first communication ports (311), and the through holes are correspondingly communicated with the first communication ports; the through holes (411) are arranged along the height direction of the sealing body portion (410) and the circumferential direction of the sealing body portion (410); two through holes (411) are arranged on the sealing body portion (410) along the circumferential direction of the sealing body portion (410); the inner surface of the sealing body portion (410) is an arc surface; and the central angle corresponding to the arc surface of the sealing body portion (410) is greater than 100 degrees and less than or equal to 180 degrees.
