Abstract

The invention discloses a double-valve-body deep-water subsidiary-parent-core tube valve, and is a combination of a double-valve-body core tube valve plate in a core tube valve master series of the original invention of the inventor. The double-valve-body deep-water subsidiary-parent-core tube valve comprises a subsidiary-valve and a parent-valve; a valve core tube which wraps around an inner cavity of an outer valve body is a fixing part penetrating through a sleeve I of the valve body, a valve body inner cavity and a sleeve II of the valve body in a coaxial mode; an axial separation layer isarranged in the middle of the valve core tube, and at least one circulation hole of an input section and an output section is formed in the axial adjacent two sides of the separation layer correspondingly; a sealing pair is formed by an annular valve core surrounding the separation layer and an annular valve seat of at least one sleeve throat part 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 in the axial hole type cooperation, and the joint part between the input section and the sleeve I and the joint part between the output section and the sleeve II are provided with seals; at least one side of the axial direction of the outer valve body is in communication with the subsidiary-valve and the front pressure of a main valve; and the two ends of the subsidiary-valve and the two ends of the inner cavity of the outer valve body are correspondingly provided with electromagnets to attract the valve body to axially reciprocate in the inner cavity of the outer valve body to realize opening and closing of driving medium to trigger the main valve to switch and open. Simple, reliable, efficient and free of leakage effects can be realized.

Description

technical field [0001] The double-body deep-water sub-mother core tube valve belongs to the field of valves. It is a combination of the dual-valve body core tube valve plates in the core tube valve parent series invented by myself, and involves remote control pressure opening and closing of the sub-mother valve group; The valve is the main valve, and the sub-valve is the solenoid valve that controls the main valve. Background technique [0002] At present, there is no normally open deep-water valve that can be remotely controlled to use a small amount of kinetic energy to open the tiny sub-valve, and use the force of the medium to close the main valve. Contents of the invention [0003] The object of the present invention is to provide a dual-valve deep-water sub-mother core tube valve to meet the production needs of deep-water special working conditions. [0004] The main technical features of the dual-body deep-water sub-mother core tube valve are: [0005] The mother ...
