Abstract

The invention provides a drive core pipe valve of a dual valve body bellows pressure cabin, and relates to pressure opening and closure, pulse, non-return, safety, regulation, pressure reduction, emergency shutoff and the like; a valve core pipe wrapped in an inner cavity of an outer valve body serves as a fixing piece to coaxially penetrate a sleeve I of a valve body, an inner cavity of the valvebody and a sleeve II of the valve body; the middle part of the valve core pipe is provided with an axial interlayer, and the two adjacent axial sides of the interlayer are each provided with at leastone radial circulation hole of an input section and an output section; a sealing pair is formed by an annular valve element surrounding the interlayer, and an annular valve seat of at least one sleeve throat of the sleeve I and the sleeve II; the input section and the sleeve I as well as the output section and the sleeve II are cooperated in an axle hole mode, and the joint parts are provided with seals; and the joint part between the input section and the sleeve I is provided with the bellows pressure cabin, and the bellows pressure cabin and a front pressure cavity of the valve are throughby manes of a channel. Under the effect of potential energy in two directions, the valve body does axial reciprocating motion in the inner cavity of the outer valve body so that the effects of openingand closure and function switching are achieved. The drive core pipe valve is safe, reliable, leak-free and multipurpose.

Description

technical field [0001] Double body bellows pressure chamber driven core tube valve belongs to the field of valves, involving pressure opening and closing valves, check valves, safety valves, pulse valves, automatic regulating valves and emergency shut-off valves. It is a core tube valve parent series invented by myself A sub-series in the dual-body core tube valve block. Background technique [0002] At present, the structure of the existing valve cannot have multiple valve functions. Contents of the invention [0003] The object of the present invention is to provide a double-valve bellows pressure chamber-driven core pipe valve to overcome the defects of existing special valves, reduce the number of pipeline valves, and meet the needs of safe production and energy saving. [0004] The present invention achieves the above object through the following technical scheme: the valve core pipe wrapped in the inner cavity of the outer valve is the sleeve pipe I, the valve body ...
