Abstract
The utility model discloses a high-pressure insulating oil pipe joint, comprising an oil joint, a nut and a copper pipe, wherein an insulating sleeve, a joint and an insulating gasket are arranged in a cavity of the nut; a through hole communicated with an internal cavity is formed in the left end face of the nut; an internal thread hole communicated with the internal cavity is formed in the right end of the nut; the oil joint is screwed in the internal thread hole; the insulating gasket is pressed on the left end face of the oil joint; the joint is pressed at the left end of the insulating gasket; the insulating sleeve is pressed on the right end face of the joint; the left end of the insulating sleeve extends out of the through hole; the copper pipe is inserted and sleeved in the insulating sleeve; a head of the copper pipe is fixed on the joint; the copper pipe is communicated with a central through hole of the oil joint. The high-pressure insulating oil pipe joint has small volume, can be mounted in a cavity with small space and is simple to mount, and the insulating sleeve and the insulating gasket can guarantee the insulating property of the high-pressure insulating oil pipe joint.
Description
Technical field:
The utility model relates to the pipe joint equipment technical field, the High-Voltage Insulation oil connection of using on the high-pressure oil passage more specifically to a kind of bearing support.
Background technique:
Sliding bearing is very extensive in the application of all trades and professions, and in some special sliding bearing using processs, the lubricating system of bearing need to adopt the mode of pure static pressure, active and static pressure combination.
At present, high-pressure oil passage in bearing support generally adopts the pattern of high pressure hose, adopt high pressure hose easy for installation and have an insulation function, but many restrictions are arranged on installation form due to high pressure hose, especially in the less cavity in space, because camber is larger, exceeded the minimum bending radius of high pressure hose, so just can't adopt flexible pipe, need a kind of little oil connection that has simultaneously insulation of volume that takies.
The model utility content:
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of High-Voltage Insulation oil connection simple, that take up room little, that volume is little of installing is provided.
The scheme that the utility model solve the technical problem is:
A kind of High-Voltage Insulation oil connection, comprise oily joint, nut and copper pipe, in described nut inner cavity, be provided with insulating bush, joint and insulating washer, the left side of nut forms the through hole communicated with internal cavities, the right-hand member of nut forms the interior threaded hole communicated with internal cavities, the oil joint is screwed onto in interior threaded hole, insulating washer is pressed against on the left side of oily joint, joint is pressed against the left end of insulating washer, insulating bush is pressed against the right side of joint, the left end of insulating bush stretches out through hole, the copper pipe sleeve is in insulating bush, the head of copper pipe is fixed on joint, copper pipe communicates with the center opening of oily joint.
Described insulating bush structure is, on the left side of ring bottom, form round ring boss, the boss sleeve also stretches out through hole, copper pipe passes boss and ring bottom successively, in its head sleeve forms on the left side of joint circular shrinkage hole, head outer wall and the joint of copper pipe are welded and fixed together, the left side of joint is pressed against on the right side of ring bottom, the right side of joint forms the central through bore communicated with circular shrinkage hole, central through bore communicates with the opening of copper pipe, the joint sleeve is in the packing ring circular shrinkage hole that the left side of insulating washer forms, the right side of joint is pressed against on the bottom end of packing ring circular shrinkage hole, on the right side of insulating washer, form the packing ring through hole communicated with the packing ring circular shrinkage hole, central through bore communicates with the packing ring through hole, the right side of insulating washer is pressed against on the left side of oily joint, the packing ring through hole communicates with the center opening of oily joint.
Outstanding effect of the present utility model is:
Compared with prior art, its volume is little, can be arranged in the less cavity in space and install, and simultaneously, it installs simple, and insulating bush and insulating washer can guarantee its insulating property simultaneously.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Embodiment, see as shown in Figure 1, a kind of High-Voltage Insulation oil connection, comprise oily joint 1, nut 2 and copper pipe 3, in described nut 2 inner cavities, be provided with insulating bush 4, joint 5 and insulating washer 6, the left side of nut 2 forms the through hole 21 communicated with internal cavities, the right-hand member of nut 2 forms the interior threaded hole 22 communicated with internal cavities, oil joint 1 is screwed onto in interior threaded hole 22, insulating washer 6 is pressed against on the left side of oily joint 1, joint 5 is pressed against the left end of insulating washer 6, insulating bush 4 is pressed against the right side of joint 5, the left end of insulating bush 4 stretches out through hole 21, copper pipe 3 sleeves are in insulating bush 4, the head of copper pipe 3 is fixed on joint 5, copper pipe 3 communicates with the center opening 11 of oily joint 1.
Described insulating bush 4 structures are, on the left side of ring bottom 41, form round ring boss 42, boss 42 sleeves also stretch out through hole 21, copper pipe 3 passes boss 42 and ring bottom 41 successively, in its head sleeve forms on the left side of joint 5 circular shrinkage hole 51, head outer wall and the joint 5 of copper pipe 3 are welded and fixed together by silver soldering, the left side of joint 5 is pressed against on the right side of ring bottom 41, the right side of joint 5 forms the central through bore 52 communicated with circular shrinkage hole 51, central through bore 52 communicates with the opening 31 of copper pipe 3, joint 5 sleeves are in the packing ring circular shrinkage hole 61 that the left side of insulating washer 6 forms, the right side of joint 5 is pressed against on the bottom end of packing ring circular shrinkage hole 61, on the right side of insulating washer 6, form the packing ring through hole 62 communicated with packing ring circular shrinkage hole 61, central through bore 52 communicates with packing ring through hole 62, the right side of insulating washer 6 is pressed against on the left side of oily joint 1, packing ring through hole 62 communicates with the center opening 11 of oily joint 1.
