Problems solved by technology

[0002] At present, there is no valve structure that can meet the requirements of using trace energy to drive the opening and closing of the valve, and can also achieve self-emergency cut-off when overpressure occurs. At the same time, it is suitable for remote control in space or deep sea.

Abstract

The invention provides a double-valve-body expansion drive core tube valve. A valve core tube wrapped in an inner cavity of an outer valve body is a fixed piece and coaxially penetrates through a sleeve I of a valve body, a valve body inner cavity and a sleeve II of the valve body. An axial isolation layer is arranged in the middle of the valve core tube. The two axial adjacent edges of the isolation layer are each provided with at least one circulating hole, and the circulating holes are formed in an input section and an output section correspondingly. An annular valve core surrounding the isolation layer forms a seal pair with an annular valve seat at a throat portion of at least one of the sleeve pipe I and the sleeve pipe II. The input section and the sleeve I is in shaft-hole type fit, the output section and the sleeve II are in shaft-hole type fit, and at least one combination portion is provided with seal. The outer diameter difference between the input section and the output section is larger than or equal to 0. A corrugated blind pipe or annular corrugated blind pipe is axially arranged between the end face of at least one of the sleeve I and the sleeve II and a corresponding inner end face of the outer valve body, wherein the corrugated blind pipe or the annular corrugated blind pipe contains saturated refrigerant and is provided with a heating rod. Under the actionof potential energy in two directions, the valve body conducts axial reciprocating movement in the inner cavity of the outer valve body to achieve opening, closing and function switching. The double-valve-body expansion drive core tube valve is safe, reliable and efficient, saves energy and has multiple functions.

Description

technical field [0001] The double-body expansion-driven core tube valve belongs to the field of valves. It is a sub-series of the dual-body core tube valve plate in the core tube valve mother series invented by me, involving on-off valves and emergency shut-off valves. Background technique [0002] At present, there is no valve structure that can satisfy the opening and closing of the valve driven by the use of trace energy, and can also achieve self-emergency cut-off when overpressure occurs, and at the same time, it is suitable for remote control in space or deep sea. Contents of the invention [0003] The object of the present invention is to provide a double-valve-body expansion-driven core tube valve to meet the requirements of production, safety and energy saving in special working conditions. [0004] The main technical features of the double valve body expansion-driven core tube valve are: the valve core tube wrapped in the inner cavity of the outer valve is a fixe...
