Description
Technical field
This utility model relates to a kind of pipe network parts, particularly has good seal performance and is easy to the spherical compensator sealing structure of maintenance.
Background technology
Ball joint compensator is for solving a kind of parts expanded with heat and contract with cold that pipeline causes due to variations in temperature, is applied to metallurgy, oil, chemical industry, electric power, light industry, weaves, in the industry such as building.Ball joint compensator uses the most in pairs, utilizes the angular displacement of spheroid to absorb or compensates the lateral displacement in the one or more direction of pipeline, and separate unit can use as the universal joint of pipeline.The advantages such as ball joint compensator has that compensation ability is big, and fluid resistance and distortional stress are little, and active force without blind flange force and to hold-down support is little.Traditional spheroidal compensator uses steel ball to coordinate with sealing member and seals, and along with the prolongation of working time, due to abrasion, steel spheroplast occurs that poorly sealed situation occurs with sealing member, causes pipeline pumped (conveying) medium to leak, even production development security incident.Change sealing member time and effort consuming, affect the work efficiency of equipment.If additionally, have molecule in the medium of conveying in pipeline, these molecules can enter into along with media flow in the spheroplast of ball joint compensator and the gap of bearing, increases the weight of to wear and tear between bearing and spheroplast, reduction bearing and spheroplast service life.
Utility model content
The purpose of this utility model is the drawback for prior art, it is provided that a kind of favorable sealing property and without dismantle ball joint compensator can realize seal maintenance spherical compensator sealing structure.
Problem described in the utility model realizes with following technical proposals:
A kind of spherical compensator sealing structure, including outer pillar and spheroplast, spheroplast is positioned at outer pillar, clutch shaft bearing, the second bearing it is symmetrical arranged between spheroplast and outer pillar, the arrival end of described spheroplast is provided with gear ash assembly, gear ash assembly is made up of dust block board and the gear ash sealing ring of annular, dust block board and gear ash ring set are in the periphery of spheroplast, dust block board and the welding inner wall of outer pillar, dust block board is provided with sealing ring mounting groove, gear ash sealing ring is positioned at sealing ring mounting groove, and the endoporus of gear ash sealing ring mates closely sealed with spheroplast periphery.
Above-mentioned spherical compensator sealing structure, the most uniform several sealing fill valve of described outer pillar, the arrival end sealing fill valve is provided with plug screw, the port of export of sealing fill valve annular region fill plug seal software between clutch shaft bearing, the second bearing, between clutch shaft bearing, the second bearing.
Above-mentioned spherical compensator sealing structure, the medium inlet end of outer pillar is provided with conical pipe, the other end seam flange of outer pillar, and the port of export suit pressing plate flange of spheroplast, flange is connected with pressing plate flange bolt.
Above-mentioned spherical compensator sealing structure, described dust block board touches clutch shaft bearing, and the front end of pressing plate flange touches the second bearing.
Being to state spherical compensator sealing structure, described sealing fill valve arranges 2-8.
This utility model is improved for improving ball joint compensator sealing property problem, its major advantage is as follows: 1, the medium inlet end in ball joint compensator spheroplast arranges gear ash assembly, gear ash assembly can effectively stop in medium molecule to enter gap between thing spheroplast and bearing, improves bearing and spheroplast service life；2, uniform sealing fill valve at pillar outside, the annular region being injected between outer pillar and spheroplast by sealing fill valve by software sealing material constitutes sealing software, so, on the one hand improve the reliability of sealing, on the other hand sealing leak can be repaired by the online software sealing material that adds, can realize sealing maintenance without dismantling ball joint compensator, thus improve the work efficiency of equipment.
Accompanying drawing explanation
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the partial enlarged view at the A of Fig. 1；
Fig. 3 is the left view of Fig. 1.
In figure, each list of reference numerals is: 1, conical pipe, 2, dust block board, 3, gear ash sealing ring, 4, spheroplast, 5, clutch shaft bearing, 6, seal fill valve, 7, seal software, and the 8, second bearing, 9, outer pillar, 10, flange, 11, pressing plate flange.
Detailed description of the invention
Referring to Fig. 1, Fig. 2, this utility model includes outer pillar 9 and spheroplast 4, and the medium inlet end of outer pillar is provided with conical pipe 1, and spheroplast is positioned at outer pillar, is symmetrical arranged clutch shaft bearing 5 and the second bearing 8 supporting spheroplast between spheroplast and outer pillar.The problem in gap between thing spheroplast and bearing is entered for solving molecule in medium, this utility model is provided with gear ash assembly, gear ash assembly is positioned at the arrival end of spheroplast, gear ash assembly is made up of the dust block board 2 of annular and the gear ash sealing ring 3 of annular, dust block board and gear ash ring set are in the periphery of spheroplast, the front end of dust block board and the welding inner wall of outer pillar, dust block board is provided with the sealing ring mounting groove for assembling gear ash sealing ring, gear ash sealing ring is positioned at sealing ring mounting groove, and the endoporus of gear ash sealing ring mates closely sealed with spheroplast periphery.Under the effect of gear ash assembly, can effectively stop molecule in medium to enter gap between thing spheroplast and bearing, reduce the abrasion between bearing and spheroplast, improve the service life of bearing.
