Abstract

A pass-through part for a hydraulic control pipe of a remote control valve, comprising a pass-through body (1), blocking elements, a control pipe (4), and a sealing element (5); the pass-through body (1) is mounted on a fixed plate (2), and the pass-through body (1) has a pass-through hole (11) in the axial direction thereof; the blocking elements comprise a first blocking element (31) and a second blocking element (32) respectively used for blocking the two open ends of the pass-through hole (11), and the first blocking element (31) and the second blocking element (32) are respectively provided with first mounting holes coaxial with the pass-through hole (11); the control pipe (4) is inserted and fitted into the first mounting hole; the sealing element (5) is made of an oil-resistant rubber material, and is sleeved on the outer wall of the control pipe (4); the sealing element (5) comprises a first flat gasket (51), a second flat gasket (52), and at least one "V"-shaped gasket (53) located between the first flat gasket (51) and the second flat gasket (52); when the blocking elements squeeze the sealing element (5), the "V"-shaped gasket (53) is deformed such that the "V"-shaped gasket (53) is separately pressed against the outer wall of the control pipe (4) and the hole wall of the pass-through hole (11). Compared with the prior art, the pass-through part for a hydraulic control pipe of a remote control valve has a good sealing effect.

Description

technical field [0001] The invention relates to the technical field of pipeline sealing, in particular to a hydraulic control pipe penetration part of a remote control valve. Background technique [0002] The general design type of the oil-water seal penetrating parts used on the deck surface of the traditional oil and crude oil tanker remote control valve hydraulic control pipe is to use stainless steel sleeves as the penetrating parts. The main body and the hull deck are welded, and the control pipe passes through the sleeves. Finally, the winding Teflon packing is filled between the sleeve and the control pipe for sealing, and finally the top of the body of the through-piece is compressed with a compression piece. [0003] During installation, the Teflon packing needs to be wound around the outer wall of the control tube. When the control tube is inserted into the through body, the packing is stuck between the outer wall of the control tube and the through body. Based on...
