Abstract

The invention provides a double-valve inner-cavity driving core tube valve. The double-valve inner-cavity driving core tube valve is a sub-series in a double-valve-body core tube valve plate in an original-creative core tube valve master series of inventor. The core tube valve is characterized in that a valve core tube wrapping an inner cavity of the outer valve body is provided with a sleeve I, avalve body inner cavity and a sleeve II, wherein a fixing piece penetrates through the sleeve I, the valve body inner cavity and the sleeve II of the valve body coaxially; an axial separation layer is arranged in the middle of the valve core tube, and at least one circulation holes of the input section and the output section are formed in the axial adjacent two sides of the separation layer respectively; a sealing pair is formed by an annular valve core surrounding the separation layer and at least one annular valve seat of sleeve throat part of the sleeve I and the sleeve II; the input section with the sleeve I and the output section with the sleeve II are in a shaft hole type cooperation, and at least one combination part is sealed; at least one end iv axial direction of the inner cavity located at the two ends of the outer valve body communicates with a pressure medium through a channel; and the valve body corresponds to the valve core tube in an axial reciprocating manner in the inner cavity of the outer valve body to realize opening and closing and function conversion. The core tube valve has the advantages of being simple and reliable in structure, free of leakage, capable of reducing purchasing, using and maintaining costs, variable in functions, and capable of improving the efficiency.

Description

technical field [0001] The core tube valve driven by the inner cavity of the double valve belongs to the field of valves. It is a sub-series of the core tube valve plate with a double valve body in the core tube valve mother series invented by me. It involves pressure opening and closing valves, opening and closing valves, check valves, Two-way control opening and closing valve, deep water control valve, two-way burst pipe automatic cut-off valve. Background technique [0002] At present, there is no valve that can be series related to pressure opening and closing valves, opening and closing valves, check valves, bidirectional control opening and closing valves, deep water control valves, and bidirectional burst pipe automatic shut-off valves. Contents of the invention [0003] The object of the present invention is to provide a double-valve inner chamber-driven core tube valve to meet the requirements of production, safety and energy saving in special working conditions. ...
