Description
[ technical field ] A method for producing a semiconductor device
The application relates to a pipeline joint, in particular to a pipeline joint for conveying liquid.
[ background of the invention ]
The pipeline joint is required to be spliced in daily life because the pipeline length is limited and the problem of the turning position of the pipeline is solved, the sealing performance of the pipeline joint is extremely important, and the pipeline joint is influenced by the production process, so that the end of part of pipelines cannot be twisted to cause air leakage, and lengthened sealing rings are adopted for the situations.
In conclusion, after the sealing ring is lengthened, the sealing ring is damaged due to the fact that the sealing ring is extruded without a vacancy and the extruded convex part is placed, and the problem to be solved by the person in the field is solved.
[ Utility model ] content
For solving among the prior art behind the extension sealing washer the sealing washer receive the extrusion not have the vacancy to put the convex part of extrusion and lead to the impaired problem of sealing washer, the utility model discloses a technical scheme for designing the pipe joint that the leakproofness is good, including connecting the body, it is equipped with the protruding piece of connecting rust proof piece, its characterized in that to connect the inner wall in the middle of the body: the right angle position that the protrusion piece with rust-resistant piece is connected still is equipped with the space that can put the sealing washer, the sealing washer with still be equipped with between the joint body inner wall the sealing washer receives the sunken groove that the deformation was placed behind the water pipe body extrusion, the sunken groove open in connect on the body inner wall.
The concave groove is in a semi-elliptical shape.
The concave groove surrounds the inner wall of the joint body for one circle.
The length of the rust-proof blocks extending to two sides is less than that of the sealing ring.
The rust-proof block is made of polypropylene.
The rust-proof block and the convex block are connected by adopting a medium-frequency heating composite method.
The rust-proof blocks on the convex blocks extend towards two sides.
The joint body is a two-way joint.
And threads matched with the water pipe body are further arranged on two sides of the inner wall of the joint body.
The utility model has the advantages that:
1. The utility model relates to a pipe joint that leakproofness is good, because the sealing washer is put on the protrusion piece, and the sealing washer is blocked so can not warp toward the center when extrudeing by rust-resistant piece, so the sealing washer just can only warp toward the inner wall side, and the inner wall side is opened there is the depressed groove, so there is sufficient space to let the sealing washer warp, consequently the sealing washer also can not damage because of the extrusion when the rust-resistant piece that connects combines with the rust-resistant piece of pipeline, has guaranteed that the leakproofness of pipeline is good.
2. The material of the rust-proof block prevents corrosion and reduces liquid resistance.
3. The slotting process is simple and convenient.
4. Simple structure and easy popularization.
5. And the connection is convenient by adopting thread combination.
[ description of the drawings ]
In order to more clearly illustrate the technical solutions in the embodiments of the present application, the drawings used in the description of the embodiments will be briefly introduced below.
Fig. 1 is an overall schematic view of the pipe joint with good sealing performance;
Fig. 2 is a schematic cross-sectional view of the pipe joint with good sealing performance.
[ detailed description ] embodiments
In order to make the technical problems, technical solutions and advantages solved by the present invention more clearly understood, referring to fig. 1, fig. 2 is a detailed description of the present invention, and it should be understood that the specific embodiments described herein are only used for explaining the present invention, and are not used for limiting the present invention.
The utility model relates to a pipe joint with good sealing performance, which comprises a joint body 1, wherein the inner wall in the middle of the joint body 1 is provided with a convex block 3 connected with a rust-proof block 2, the right-angled position where the convex block 3 is connected with the rust-proof block 2 is also provided with a gap for placing a sealing ring 4, a concave groove 5 for placing the sealing ring 4 in a deformed way after being extruded by a water pipe body 6 is also arranged between the sealing ring 4 and the inner wall of the joint body 1, the concave groove 5 is arranged on the inner wall of the joint body 1, the sealing ring is placed on the convex block, and the sealing ring is blocked by the rust-proof block so that the sealing ring can not deform towards the center when being extruded, so that the sealing ring can only deform towards the inner wall side, the concave groove is arranged on the inner wall side, so that enough space is provided for deforming the sealing ring, and the sealing ring can not be damaged by extrusion when the, the good sealing performance of the pipeline is ensured.
The concave groove 5 is in a semi-elliptical shape, and the grooving process of the concave groove in the shape is simple and convenient.
The sunken groove 5 winds the inner wall of the joint body 1 for one circle, and more placing spaces are formed after the sealing ring 4 is extruded.
the length of the rust-proof blocks 2 extending towards two sides is less than that of the sealing ring 4, and after the two rust-proof blocks 2 are combined, the sealing ring 4 is compressed, so that the sealing effect is good.
The rust-proof block 2 is made of polypropylene, and prevents fluid in the pipe from contacting the steel pipe to generate oxidation corrosion.
The rust-proof block 2 and the convex block 3 are connected by adopting a medium-frequency heating compounding method, and plastic cracking, degumming and steel-plastic cracking cannot occur.
The rust-proof blocks 2 on the convex blocks 3 extend towards two sides and can block the sealing ring 4 from moving towards the center during compression.
The joint body 1 is a two-way joint, and the pipeline transportation effect can be achieved only by the structure.
The two sides of the inner wall of the joint body 1 are also provided with threads matched with the water pipe body 6, and the thread type structure is convenient to install.
The working principle is as follows: the pipeline body 6 is twisted into the joint body 1 through threads, the compression sealing ring 4 is compressed in the twisting process until the pipeline body 6 is combined with the rust-proof block 2 on the joint body 1, at the moment, the sealing ring 4 can only extend towards the inner wall after being compressed, and the inner wall is provided with a concave groove 5, so that the convex part of the sealing ring 4 after being compressed is arranged in the groove.
The utility model relates to a pipe joint that leakproofness is good, because the sealing washer is put on the protrusion piece, and the sealing washer is blocked so can not warp toward the center when extrudeing by rust-resistant piece, so the sealing washer just can only warp toward the inner wall side, and the inner wall side is opened there is the depressed groove, so there is sufficient space to let the sealing washer warp, consequently the sealing washer also can not damage because of the extrusion when the rust-resistant piece that connects combines with the rust-resistant piece of pipeline, has guaranteed that the leakproofness of pipeline is good.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
