Background technique
In the prior art, people generally use pipe fitting to carry out the connection between pipeline and pipeline, but this connection is tied
Structure usually requires intermediate installation cushion rubber and is sealed, as shown in Figure 1, the shape of cushion rubber is circular ring shape, cushion rubber packet in the prior art
The both ends for including cushion rubber ontology 11 are respectively provided with the side wall 12 annular in shape being linked together with cushion rubber ontology 11,12 inward flange of side wall
Axis inwardly convexes into ring lip 13.Connection type and sealing principle are: cushion rubber covered on pipeline of two pipe ends with annular groove,
Then the both ends of pipe fitting are buckled in blending bolt in the annular groove of two pipe ends, nut fastening.Due to the inner peripheral surface of ring lip 13
Contour line be parallax with the axis of cushion rubber at setting angle, when fluid passes through pipeline, fluid matasomatism is in ring lip 13
Radial component can be generated on inner surface, radial component compression ring lip 13 is adjacent to pipeline outer wall, can play self sealing action.
And in the prior art due to the inner peripheral surface of cushion rubber ontology 11 be it is smooth, with the aging of cushion rubber, in squeezing for pipeline
Pressure easily causes the inner peripheral surface of ring lip 13 and the inner peripheral surface of cushion rubber ontology 11 to press together and (the rubber self-dissolving that sticks together
Property), fluid cannot flow between ring lip 13 and cushion rubber ontology 11, so that ring lip 13 be made to lose leakproofness and cause to leak.
The raised inner peripheral surface and cushion rubber ontology 11 to prevent ring lip 13 of the both ends setting of the inner peripheral surface of cushion rubber ontology 11 at present
Inner peripheral surface press together and stick together, such as the patent of the patent No. " CN201520902437.4 ", but protrusion is only
The both ends of the inner peripheral surface of cushion rubber ontology 11 are set, the inner peripheral surface middle section of cushion rubber ontology 11 or smooth, if cushion rubber aging
When serious, the inner peripheral surface of ring lip 13 still can press together viscous with the middle section of the inner peripheral surface of cushion rubber ontology 11
Even.
Utility model content
Problem to be solved in the utility model is against the above deficiency, to provide a kind of plough groove type pipe joint and prevent adhesion cushion rubber,
Cushion rubber can be effectively prevent to stick together, improve the service life of cushion rubber, improved the sealing performance of cushion rubber, greatly reduce
The replacement frequency of cushion rubber, it is easy to use.
To solve the above-mentioned problems, the utility model uses following technical scheme:
A kind of plough groove type pipe joint prevents adhesion cushion rubber, includes cushion rubber ontology, the both ends of cushion rubber ontology are equipped with a side annular in shape
Wall, side wall are linked together with cushion rubber ontology, and the inward flange axial direction convex of side wall is formed with ring lip, on the cushion rubber ontology inner peripheral surface
Equipped with raised member, liquid bath was formed between raised member, liquid can be flowed through from crossing in liquid bath, and raised member is for preventing ring
The inner peripheral surface of lip and cushion rubber ontology sticks together.
Further, the raised member includes several first projection pieces and/or the second projection piece, and the first projection piece is along glue
The axial direction of circle ontology inner peripheral surface is uniformly arranged, radially uniform setting of second projection piece along cushion rubber ontology inner peripheral surface.
Further, the shape of first projection piece is cusped edge shape, and the first projection piece is the low setting in intermediate high both ends.
Further, first projection piece point two rows are uniformly arranged on the both ends of cushion rubber ontology inner peripheral surface, and two ranked first
The tip portion of projection piece, which overlaps, to be staggered.
Further, the shape of second projection piece is rectangular prismatic.
Further, the raised member is 0.8-1.2mm relative to the height of cushion rubber ontology inner peripheral surface.
The utility model is had the following technical effect that compared with prior art using above technical scheme
Cushion rubber described in the utility model can effectively prevent cushion rubber to stick together, and improve the service life of cushion rubber, mention
The high sealing performance of cushion rubber, greatly reduces the replacement frequency of cushion rubber, easy to use.
The utility model is described in detail with reference to the accompanying drawings and examples.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of cushion rubber in the utility model background technique；
Attached drawing 2 is the structural schematic diagram of cushion rubber in the utility model embodiment；
Attached drawing 3 is the revolved section structural schematic diagram of A-A in Fig. 1 in the utility model embodiment；
In figure: 1- cushion rubber ontology, 2- side wall, 3- ring lip, 4- raised member, the first projection piece of 5-, the second projection piece of 6-.
Specific embodiment
Embodiment 1, as shown in Figure 2 to Figure 3, a kind of plough groove type pipe joint prevent adhesion cushion rubber, including cushion rubber ontology 1, cushion rubber
The both ends of ontology 1 are equipped with a side wall 2 annular in shape, and side wall 2 is linked together with cushion rubber ontology 1, the inward flange axial direction convex of side wall 2
It is formed with ring lip 3, the contour line of 3 inner peripheral surface of ring lip is obliquely installed relative to the axial line of cushion rubber ontology 1,1 inner circumferential of cushion rubber ontology
Face is equipped with raised member 4, liquid bath is formed between raised member 4, liquid can be flowed through from crossing in liquid bath, in cushion rubber ontology 1
