WIPO Patent Application WO/2018/214323
Kind Code:
A1
Abstract:
A one-way valve, comprising: a valve body (10), a valve core (20), a spring (30), and a first seal ring (40). The valve body is provided with a channel (11). The lateral wall of the channel has a first flange (12) provided around its circumference. The valve core is mounted in the channel and can move along the channel; the lateral wall of one end of the valve core is provided with a second flange (21), and the lateral wall of the other end of the valve core has a first mounting groove (22) provided around its circumference. The spring is sleeved on the valve core and is located in the channel. The spring is located between the first flange between the second flange. The first seal ring is detachably mounted in the first mounting groove, and the first seal ring is used for abutting against the side of the first flange away from the second flange. Because the first seal ring is detachably mounted in the first mounting groove, when a maintenance operation is performed on the one-way valve, the first seal ring is detached first, the valve core can be extracted from the channel. It is convenient to detach the valve core, without overall replacement, and therefore, the usage cost can be reduced.
