Problems solved by technology

[0003] At present, the localization of special-purpose valves used in high temperature and high pressure, low temperature vacuum, toxic and harmful, nuclear energy, deep sea oil and gas, ships and deep sea submarines, aerospace and other working conditions and environments is low. At the same time, foreign products also need to be more perfect. , Improvement and supplementation, the drive of the existing valve also needs drive energy, drive system and actuator, and its cost price, use price and maintenance price factors cannot be ignored

Abstract

A double valve body core pipe valve is the main part of a double valve body core pipe valve plate in a core pipe valve mother series invented by the inventor originally. A valve core pipe wrapped in an outer valve body inner cavity is a fixed part which coaxially penetrates through a sleeve pipe I of a valve body, a valve body inner cavity and a sleeve pipe II of the valve body. An axial interlayer is arranged in the middle of the valve core pipe. The two adjacent axial edges of the interlayer are provided with at least one radial communicating hole of the input section and the output section.An annular valve core surrounding the interlayer and an annular valve seat of the larynx part of at least one of the sleeve pipe I and the sleeve pipe II form a sealing pair. The difference of the outer diameters of the input section and the output section is larger than or equal to 0. The input section and the sleeve pipe I as well as the output section and the sleeve pipe II are in shaft hole type fit, and at least one combined part is sealed. Under the action of bidirectional potential energy, the valve body does axial reciprocating motion in an outer valve body inner cavity, and opening,closing and function conversion are achieved. Opening and closing resistance is small, leakage is avoided, extending characteristics are wide, safety, reliability and flexibility are achieved, maintenance is reduced, efficiency is improved, and the double valve body core pipe valve adapts to various work conditions.

Description

technical field [0001] The double valve body core tube valve of the present invention belongs to the field of valves, and relates to pressure opening and closing valves, opening and closing valves, speed opening and closing valves, regulating valves, safety valves, check valves, pressure reducing valves, pressure limiting valves, isolation valves, emergency Shut-off valve, and two-way burst pipe emergency shut-off valve, etc.; it is the main part of the double valve body core tube valve plate in the core tube valve parent series invented by me, including the double valve body control core tube valve and the double valve body self-driven Core pipe valve; the application of the present invention is the main application of the double valve body core pipe valve series. valves for various purposes. [0002] The double-body core tube valve adopts a double-body structure without external leakage; the inner seal adopts a sleeve-type structure, that is, the axially moving annular valv...
