Summary of the invention
Technical problem to be solved in the utility model is to overcome reconstruction of recycle hydrogen compressor for hydrocracking run duration, instrument flush type thermal resistor joint sealing poor effect, occur for a long time the shortcoming of oil leakage phenomenon providing the compressor flush type thermal resistance wire outlet oil-leakage-prevention joint that a kind of structure is simple, easy for installation, cost of production is low, oil-leakage-prevention is respond well.
The adopted technological scheme that solves the problem is: be processed with center hole b at left connector center, oil-leakage-prevention rubber pad is provided with in the right-hand member of left joint, the same circumferential position of axis of oil-leakage-prevention rubber pad is processed with threading hole a, the right-hand member of left joint is provided with right connector, and the central position of right connector is processed with center hole c.
The oil-leakage-prevention rubber pad of the present utility model threading hole a that axially same circumferential position is processed has 2 ~ 4, and the aperture of threading hole a is 3 ~ 5mm.
The aperture of the threading hole a of the axial same circumferential position processing of oil-leakage-prevention rubber pad 2 of the present utility model is identical.
The right-hand member of left connector center hole b of the present utility model is cone shape hole, and the left side of oil-leakage-prevention rubber pad is the cone, the right side that match with the cone shape hole of center hole b right-hand member in left joint is cylindrical body; The center hole left end of described right connector is processed with internal thread, and the aperture of left end center hole is identical with left joint right-hand member external diameter, and the aperture of the center hole c of right connector is identical with the aperture of the center hole b of left joint.
Because the utility model is provided with the oil-leakage-prevention rubber pad matched with cone shape hole in the cone shape hole of left connector center hole right-hand member, while fastening left joint, cylinder type leakproof lubricating pad is by compressive strain, fill the cone shape hole of full left connector center hole right-hand member, reach good sealing effect, the axial position of oil-leakage-prevention rubber pad is processed with threading hole, the elongation line of thermal resistor is from wherein passing through, effectively prevent instrument and the electrical connector oil leakage phenomenon of Large-scale machine set, it is simple that the utility model has structure, easy for installation, cost is low, the advantages such as oil-leakage-prevention successful, can use on reconstruction of recycle hydrogen compressor for hydrocracking.
