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.
