一种防泄漏阀门
摘要：
本发明揭示了一种防泄漏阀门，包括阀体(1)、安装于所述阀体(1)内的阀芯(2)、与所述阀芯(2)相配合的阀座(3)以及阀笼(4)，所述阀笼(4)与所述阀座(3)相配合连接，所述阀笼(4)上设置有环形缺口(5)，所述环形缺口(5)内设置有密封圈(6)，所述密封圈(6)可与所述阀芯(2)外周面(17)相贴合，所述密封圈(6)开设有凹槽(9)，所述阻挡壁(8)设置有至少一个与所述凹槽(9)相通的小孔(10)，所述阀笼(4)包括与之一体成型的阻挡壁(8)，所述阻挡壁(8)部分挡住所述密封圈(6)。本发明的阀门可以在阀芯(2)与阀座(3)的接触面发生磨损泄露后依旧保持密封，并且流体压力越大，密封效果越好。
摘要（英）：

The invention discloses an anti-leakage valve. The anti-leakage valve comprises a valve body (1), a valve core (2) mounted in the valve body (1) as well as a valve seat (3) and a valve cage (4) whichare matched with the valve core (2); the valve cage (4) and the valve seat (3) are connected in a matched manner; a circular gap (5) is formed in the valve cage (4); a sealing ring (6) is arranged inthe circular gap (5) and can fit the outer circumferential surface (17) of the valve core (2); a groove (9) is formed in the sealing ring (6); a stop wall (8) comprises at least one small hole (10) communicating with the groove (9); the valve cage (4) comprises the stop wall (8) integrally formed with the valve cage (4); and the stop wall (8) partially shields the sealing ring (6). According to the valve, sealing can still be kept after wear leakage occurs on the contact surface of the valve core (2) and the valve seat (3), and the higher the fluid pressure is, the better the sealing effect is.
