[0017] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figure 1-5 As shown, the embodiment of the utility model includes:

[0019] A pipeline gas quick-change connector comprises a gooseneck tube body 1, a tube clamp base 2, a slot 3, a sealing ring 4, a countersunk hole 5, a positioning plug 6, and an alloy steel pressing sheet 7. The port of the gooseneck tube body 1 is provided with an integrally formed tube clamp base 2, the inner wall of the tube clamp base 2 is provided with a slot 3 surrounding the port of the gooseneck tube body 1, the slot 3 is inlaid with a sealing ring 4 and has a plurality of countersunk holes 5 therein, the sealing ring 4 is provided with an arc-shaped base surface 8 that fits the inner wall of the slot 3, the arc-shaped base surface 8 is provided with a positioning plug 6 that matches and fills the countersunk hole 5, and the tube clamp base 2 is overlapped with an alloy steel pressing sheet 7.

[0020] One end of the pipe clamp base 2 is provided with an integrally formed shaft seat 9 , and one end of the alloy steel pressing sheet 7 is connected to the shaft seat 9 via a rotating shaft 10 .

[0021] Furthermore, threaded holes are coaxially formed at the other end of the pipe clamp base 2 and the other end of the alloy steel pressing plate 7, and bolts 11 are locked in the threaded holes.

[0022] Furthermore, the gooseneck tube body 1 is provided with an integrally formed reinforcing rib 12 , and the reinforcing rib 12 covers the entire outer wall of the tube clamp base 2 .

[0023] Furthermore, the shapes of the pipe clamp base 2 and the alloy steel pressing sheet 7 are symmetrical to each other, both being semicircular ring shapes.

[0024] Furthermore, there are two countersunk holes 5, which are arranged on two opposite sides of the end of the gooseneck tube body 1 respectively. The wall thickness of the sealing ring 4 is the largest at the positioning plug 6 and the smallest at the center line of the positioning plug 6. The sealing ring 4 protrudes from the inner wall surface of the pipe clamp base 2.

[0025] Generally, a three-way joint is needed to realize flow diversion when taking gas from the main pipeline 100. However, when it is necessary to divert gas from the horizontally arranged main pipeline 100 in the direction of gravity, the condensed water in the main pipeline 100 is easy to flow to the downstream gas taking pipeline, thereby affecting the normal operation of the downstream equipment. Therefore, this product adopts a gooseneck pipe body 1 instead of an ordinary three-way joint to take gas from the waistline of the pipe wall of the main pipeline 100, so as to prevent the condensed water in the main pipeline 100 from being discharged to the downstream pipeline.

[0026] When the port of the gooseneck tube body 1 is docked with the main pipeline 100, a sealing ring 4 needs to be set at the docking interface. Due to the material characteristics of the sealing ring 4, the sealing ring 4 is prone to fall off or deviate from the original position during the docking installation process, which in turn causes gas leakage in the pipe. In order to solve this problem, this product adopts the method of additionally opening a countersunk hole 5 in the card slot 3 and correspondingly setting a positioning plug 6 on the sealing ring 4 to enhance the stability of the sealing ring 4 in the card slot 3. During the installation process, since the positioning plug 6 is tightened in the countersunk hole 5, it is difficult for the sealing ring 4 to fall off.

[0027] The sealing ring 4 adopts a special-shaped structural design, and presents an arc shape when viewed from the side. Its arc-shaped base surface 8 fits tightly with the card slot 3. The outer surface of the sealing ring 4 is also provided with multiple sealing ridges around the gooseneck tube body 1. The multiple sealing ridges construct multiple sealing surfaces, forming multiple crimping lines, making the fitting surface wider. The sealing ridges protrude from the inner wall surface of the pipe clamp base 2, so that it can fit tightly with the main pipe 100, avoid deformation of the fitting surface, have a better protection effect against vibration, and significantly improve the air tightness of the tube body.

[0028] The alloy steel pressing sheet 7 is also called a male part. The alloy steel material has a high tensile strength and can effectively reduce the risk of cracking caused by tightening overload or material fatigue.

[0029] Since the sealing ring 4 is connected to the pipe clamp base 2 by means of the positioning plug 6, the product as a whole can achieve a blind installation effect, and the sealing ring 4 does not need to be subjected to additional gluing treatment.

[0030] In summary, the utility model provides a pipeline air extraction quick-change joint, which adopts a gooseneck design to solve the problem of condensed water drainage, and adopts a countersunk hole 5 to tighten the positioning plug 6 to improve the sealing performance of the interface, replacing the gluing process and significantly improving the service life.

[0031] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
