Embodiment
Existing accompanying drawings pressure type of the present utility model does not have the specific embodiment of the valve that leaks.
As shown in Figure 1, a kind of pressure type that the utility model proposes does not have the valve of leaking, has a valve plate 1, this valve plate connects one and opens and closes drive unit 3, the bottom of described valve plate 1 is provided with a valve pipe 2, wherein, described valve plate 1 is made of last valve plate 11 and lower valve plate 12, and 11,12 of upper and lower valve plates are provided with a Flexible Connector 10; Described valve pipe 2 comprises upper valve tube 21 and lower valve tube 22, and the bore of lower valve tube 22 is less than upper valve tube 21 bores, constitutes a holding cavity 4 between this upper and lower valve pipe, and this holding cavity 4 is connected with a pressure compensator.The described valve plate 11 of going up constitutes a upper gas chamber with its upper space, and described holding cavity 4 also can be described as lower chamber.
