Description

Technical Field

[0001] This utility model belongs to the field of natural gas extraction technology, specifically relating to a transportation pipeline that facilitates natural gas detection and sampling. Background Technology

[0002] Natural gas, like crude oil, is buried in underground, closed geological structures. Some are stored in the same stratum as crude oil, while others exist separately. Natural gas stored in the same stratum as crude oil is extracted along with the crude oil and is transported through pipelines.

[0003] After existing natural gas transmission pipelines are installed and put into use, it is necessary to test and sample the natural gas in the pipeline. However, it is often inconvenient to sample the natural gas in the pipeline, and natural gas leakage is prone to occur during sampling, which affects the stability of the transmission pipeline during sampling and makes it impossible to test the flow rate of the natural gas pipeline. Utility Model Content

The inner side of the fixed seat is hinged with a first abutment plate and a second abutment plate via a rotating shaft. The lower sides of the first abutment plate and the second abutment plate are both fixedly connected with compression springs. The other end of the compression springs is disposed on the inner side of the fixed seat.

Multiple sleeve seats are arranged in a circular array around the center of the mounting seat on the circumferential side of the mounting seat. Multiple mounting screws are provided on the connecting flanges and are respectively inserted into the sleeve seats. The mounting screws pass through the sleeve seats and are inserted into another connecting flange. The end of the mounting screw is screwed with a fixing bolt that is in close contact with the connecting flange. A flow meter is fixedly connected to the top of the mounting seat.

[0010] Preferably, the mounting base and the connecting flange are provided with a second sealing gasket that is in contact with each other on their opposite sides.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0015] Please see Figures 1-3 As shown, a pipeline for facilitating natural gas detection and sampling includes: Circulation channel 1; Connecting flange 2 is fixedly connected to the end of the flow pipe 1; Flow measuring mechanism 3 is installed between two adjacent connecting flanges 2; Sealing mechanism 4 is provided on the circumferential side of the flow pipe 1; Detector 5 is sealed and inserted at the end of sealing mechanism 4.

[0016] Specifically, the sealing mechanism 4 includes a fixed seat 401 disposed on the circumferential side of the flow pipe 1. The inner side of the fixed seat 401 is hinged with a first abutting plate 403 and a second abutting plate 405 via a rotating shaft 402. The lower sides of the first abutting plate 403 and the second abutting plate 405 are both fixedly connected with compression springs 404. The other end of the compression springs 404 is disposed on the inner side of the fixed seat 401.

[0017] Specifically, the outer surfaces of the first abutting plate 403 and the second abutting plate 405 are the same size and shape, the opposite sides of the first abutting plate 403 and the second abutting plate 405 are both inclined, and the opposite sides of the first abutting plate 403 and the second abutting plate 405 are in contact.

[0018] Specifically, the opposing sides of the first abutment plate 403 and the second abutment plate 405 are bonded with first sealing gaskets that are in contact with each other by sealant. Specifically, through the movable rotation between the first abutment plate 403 and the rotating shaft 402, and the elastic extension and contraction between the first abutment plate 403 and the compression spring 404, the movable rotation operation between the first abutment plate 403 and the second abutment plate 405 can be performed, thereby facilitating the quick sealing operation of the insertion hole after the detector 5 is pulled out.

[0019] As can be seen from the above, when the staff conducts natural gas testing and sampling in the flow pipeline 1, the staff inserts the detector 5 into the fixed seat 401. When the detector 5 is inserted, it can push the first abutment plate 403 and the second abutment plate 405 to rotate downward, so that the detection end of the detector 5 can be inserted into the flow pipeline 1 to contact the natural gas in the flow pipeline 1 and sample and detect it, which improves the convenience of the staff when conducting natural gas testing and sampling. After the detector 5 has been inserted and tested inside the flow pipeline 1, the detector 5 needs to be pulled out. When the detector 5 is pulled out upward, the first abutment plate 403 and the second abutment plate 405 can rotate upward under the action of the compression spring 404, so that the inclined surfaces of the first abutment plate 403 and the second abutment plate 405 contact each other, and the fixed seat 401 is sealed under the action of the first sealing gasket, realizing the rapid sealing of the insertion hole and preventing natural gas leakage in the flow pipeline 1. Example 2

[0020] refer to Figure 1 and Figure 3 As shown, the flow measuring mechanism 3 includes a mounting base 301 that is sealed between two adjacent connecting flanges 2. Multiple sleeve seats 303 are integrally formed in a ring array around the center of the mounting base 301 on the circumferential side. Multiple mounting screws 302 are threaded onto the connecting flanges 2 and are respectively inserted into the sleeve seats 303. The mounting screws 302 pass through the sleeve seats 303 and are inserted into the other connecting flange 2. The ends of the mounting screws 302 are screwed with fixing bolts 305 that are in close contact with the connecting flanges 2. A flow meter 304 is fixedly connected to the top of the mounting base 301.

[0021] Specifically, the mounting base 301 and the connecting flange 2 are provided with a second sealing gasket that is in contact with each other on their opposite sides.

[0022] As can be seen from the above, when real-time monitoring of the natural gas flow rate inside the circulation pipeline 1 is carried out, the staff first installs the mounting base 301 between two adjacent connecting flanges 2 using screws 302 and fixing bolts 305, and achieves sealing contact between the mounting base 301 and the connecting flanges through the second sealing gasket, preventing the natural gas in the circulation pipeline 1 from leaking out, thus realizing the rapid installation of the mounting base 301. At the same time, the flow meter 304 on the mounting base 301 can measure the natural gas flow rate in the circulation pipeline 1.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
