压力平衡的瓣阀
摘要：
在根据本发明的压力平衡瓣阀中，中空的阀体(1)内的活动的节气门(5)包括两个隔开的阻塞装置(8，9)，它们分别与两个环形阻塞座(6，7)配合。平衡通道(10)平衡该活动的节气门(5)两侧的流体压力。阻塞装置中的一个(9)包括挠性弹力的径向环形边(11)，该径向环形边(11)倾斜地抵靠在所述环形阻塞座之一(7)上并且实现了令人满意的双重密封。
摘要（英）：

In a pressure balanced flap valve according to the invention, a movable throttle valve (5) in a hollow valve body (1) comprises two blocking apparatuses (8, 9) separated from each other and matched with two annular blocking seats (6, 7), respectively. A balanced passage (10) balances fluid pressure at two sides of the movable throttle valve (5). One (9) of the blocking apparatuses comprises an elastically flexible annular radial lip (11) which supports against the blocking seat (7) slantingly and realizes satisfied double seal.
