Description

Technical Field

[0001] This utility model relates to the field of pipeline installation technology, and in particular to a quick-connect leak-proof connector for gas extraction pipelines. Background Technology

[0002] Gas extraction pipelines typically use PN16 standard flanges with sealing face types of RF raised face / FF flat face. Bolts are symmetrically pre-tightened and fitted with spiral wound gaskets (graphite-filled) or nitrile rubber gaskets. Advantages: High pressure resistance (burst pressure ≥ 8 MPa), suitable for main pipelines with extraction negative pressure > 13 kPa.

[0003] However, gas extraction pipelines with this type of flange connection require multiple bolts to be tightened during installation. Due to the high precision required for tightening force, the pipeline installation operation is slow.

[0004] Therefore, it is necessary to provide a quick-connect leak-proof connector for gas extraction pipelines to solve the above-mentioned technical problems. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a quick-connect leak-proof joint for gas extraction pipelines, which can improve the installation speed of gas extraction pipelines.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] The quick-connect leak-proof joint for gas extraction pipelines includes: a pipeline body and a connecting pipe; both ends of the pipeline body are provided with a first connecting mechanism; both ends of the connecting pipe are provided with a second connecting mechanism; the first connecting mechanism includes a connecting plate fixedly installed at the end of the pipeline body, with three clearance openings evenly provided on the connecting plate, and three cone plates evenly installed on one side of the connecting plate, the thickness of the cone plates gradually increasing along the circumferential direction, and a limiting groove provided on the cone plates; the second connecting mechanism includes a pipe plug integrally formed at the end of the connecting pipe, a sealing ring being fitted on the pipe plug, a sleeve integrally formed on the outside of the connecting pipe, three clamping blocks evenly installed on the inside of the sleeve, and a limiting protrusion provided on one side of the clamping block, the limiting protrusion being adapted to the limiting groove.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0027] Example 1:

[0028] like Figure 1-7 As shown, the quick-connect leak-proof joint for gas extraction pipelines provided by this utility model includes: a pipeline body 1 for gas transportation and a connecting pipe 2 for connecting two pipeline bodies 1, with both ends of the connecting pipe 2 connected to the two pipeline bodies 1. Each end of the pipeline body 1 is provided with a first connecting mechanism; each end of the connecting pipe 2 is provided with a second connecting mechanism; the first connecting mechanism is connected to the second connecting mechanism. The first connecting mechanism includes a connecting plate 11 (integrally formed) fixedly installed at the end of the pipeline body 1. Three clearance openings 14 are evenly provided on the connecting plate 11, and three conical plates 15 are evenly installed on one side of the connecting plate 11. The thickness of the conical plates 15 gradually increases along the circumferential direction, and a limiting groove 16 is provided on the conical plates 15. The second connecting mechanism includes a pipe plug 21 integrally formed at the end of the connecting pipe 2. A step is formed at the connection between the pipe plug 21 and the connecting pipe 2, which is used to install the sealing ring 3. A sleeve 22 is integrally formed on the outside of the connecting pipe 2. Three locking blocks 23 are evenly installed on the inside of the sleeve 22. A limiting protrusion 24 is provided on one side of the locking block 23, and the limiting protrusion 24 is adapted to the limiting groove 16. Figure 7As shown, the cone plates 15 at both ends of the pipe body 1 are installed in opposite directions, so that the thickness of all cone plates 15 gradually increases when viewed in the clockwise rotation direction of the pipe body 1. The clamping blocks 23 that are adapted to the cone plates 15 are set in the same design manner, which will not be described in detail here. In use, align the connecting pipe 2 with the axis of the pipe body 1, insert the pipe plug 21 into the pipe body 1, and allow the locking block 23 to pass through the clearance opening 14. Then rotate the connecting pipe 2, causing the locking block 23 to slide along the inclined surface of the cone plate 15. Due to the change in thickness of the cone plate 15, the connecting pipe 2 moves axially, and the pipe plug 21 is inserted deeper into the pipe body 1, achieving the insertion of the connecting pipe 2 and the pipe body 1. The sealing ring 3, fitted at the base of the pipe plug 21, is squeezed by the stepped surface and the end face of the connecting plate 11, achieving a seal. When the connecting pipe 2 rotates until the limiting protrusion 24 is embedded in the limiting groove 16, stop rotating the connecting pipe 2. Because the limiting protrusion 24 is embedded in the limiting groove 16, the connecting pipe 2 will not continue to rotate, thus playing a limiting role. In this way, a quick connection between the connecting pipe 2 and the pipe body 1 is achieved. The connection of the other end of the connecting pipe 2 to the pipe body 1 can be carried out in the same way as above, and will not be repeated here. Because the traditional flange connection method is avoided, the quick connection and installation of the gas extraction pipeline can be achieved. It is worth noting that the equipment or pipeline connected to the pipeline body 1 should be provided with at least one second connection mechanism for connecting to the pipeline body 1.

[0029] By setting up a pipeline body 1 and a connecting pipe 2, and setting a first connecting mechanism at both ends of the pipeline body 1 and a second connecting mechanism at both ends of the connecting pipe 2, the two pipeline bodies 1 can be quickly installed and connected by using the quick connection between the first connecting mechanism and the second connecting mechanism, which can greatly improve the installation speed of the gas extraction pipeline.

[0030] Example 2:

[0031] like Figure 1 and Figure 6 As shown, in this embodiment, an external thread 12 is provided on the pipe body 1, and a threaded pipe 13 is installed on the pipe body 1. The threaded pipe 13 is adapted to the external thread 12. When in use, the threaded pipe 13 is screwed onto the external thread 12, and one end of it is tightly pressed against the washer 5 at the end of the sleeve 22, thereby further improving the connection stability between the connecting pipe 2 and the pipe body 1.

[0032] By installing a threaded pipe 13 on the pipe body 1 and using the threaded pipe 13 to press tightly against the end of the sleeve 22, the connection stability between the connecting pipe 2 and the pipe body 1 can be improved.

[0033] Example 3:

[0034] like Figure 4-6As shown, four mounting tubes 25 are evenly installed on the outside of the sleeve 22 and the threaded tube 13. The mounting tube 25 has an axial insertion hole 251. When in use, when the limiting protrusion 24 is embedded in the limiting groove 16, the sleeve 22 and the mounting tube 25 of the threaded tube 13 are aligned one by one. The pin 4 is inserted into the mounting tube 25 to prevent the threaded tube 13 from reversing and improve the connection stability.

[0035] By providing an installation tube 25 on the sleeve 22 and the threaded tube 13, the reverse rotation of the threaded tube 13 can be prevented, thus improving the connection stability.

[0036] Example 4:

[0037] like Figure 4 As shown, a socket 252 is provided radially on the mounting pipe 25. When rotating the threaded pipe 13 or the connecting pipe 2, a steel rod or other tool can be inserted into the socket 252 to increase the lever arm and make it easier to operate. It is worth noting that this type of mounting pipe 25 can also be provided on the pipe body 1, which will not be described in detail here.

[0038] By radially opening an insertion interface 252 on the mounting tube 25, the connecting tube 2 and the threaded tube 13 can be easily rotated.

[0039] Working principle: In use, align the connecting pipe 2 with the axis of the pipe body 1, insert the pipe plug 21 into the pipe body 1, and allow the locking block 23 to pass through the clearance opening 14. Then rotate the connecting pipe 2, causing the locking block 23 to slide along the inclined surface of the cone plate 15. Due to the change in thickness of the cone plate 15, the connecting pipe 2 moves axially, and the pipe plug 21 is inserted deeper into the pipe body 1, achieving the connection between the connecting pipe 2 and the pipe body 1. The sealing ring 3, fitted at the base of the pipe plug 21, is squeezed by the stepped surface and the end face of the connecting plate 11, achieving a seal. When the connecting pipe 2 rotates until the limiting protrusion 24 is embedded in the limiting groove 16, stop rotating the connecting pipe 2. Because the limiting protrusion 24 is embedded in the limiting groove 16, the connecting pipe 2 will not continue to rotate, thus playing a limiting role. In this way, the quick connection between the connecting pipe 2 and the pipe body 1 is achieved. The connection of the other end of the connecting pipe 2 to the pipe body 1 can be carried out in the same way as above, and will not be repeated here. This enables the quick connection and installation of gas extraction pipelines.
