Description

Technical Field

[0001] The utility model provides a natural gas sampling and pressurizing device, which relates to the technical field of natural gas sampling and pressurizing. Background Art

[0002] Natural gas refers to a mixture of hydrocarbons and non-hydrocarbon gases naturally stored in the strata. Natural gas is stored in porous rock formations underground, including oilfield gas, gas field gas, coalbed methane, mud volcano gas and biogenic gas, and a small amount is also found in coal seams. It is a high-quality fuel and chemical raw material.

[0003] The patent with the patent authorization announcement number CN220170655U discloses a pressurizing device for natural gas sampling. The patent controls the first solenoid valve to open and fills the natural gas chamber with water from the water inlet pipe, and injects natural gas from the air inlet pipe into the natural gas chamber of the box body, so that the water in the natural gas chamber is pressed into the water storage chamber through the connecting pipe. After the water storage chamber is full of water, the step float plate contacts the limit switch, so that the fourth solenoid valve is closed, the air pump is started to pump the natural gas in the natural gas chamber into the gas storage tank, and the air supply pump is started to push the water in the water storage chamber back to the natural gas chamber, so that the natural gas in the natural gas chamber is pushed into the gas storage tank. However, the pressurizing device provided by the patent still has shortcomings in actual use. When the connection between the air pump and the box body and the gas storage tank is not tight enough, natural gas leakage accidents are likely to occur, which not only leads to waste of resources, but also easily causes safety accidents.

[0004] Therefore, it is necessary to provide a natural gas sampling and pressurizing device capable of detecting natural gas leakage. Utility Model Content

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0024] Example 1: A natural gas sampling and pressurizing device, see Figure 1-Figure 3 As shown, it includes a mounting platform 1, a pressure pump 2, a gas supply bottle 3, a first transport pipeline 4, a second transport pipeline 401, a manual valve 5 and a gas storage bottle 6. A gas supply bottle 3 filled with natural gas is placed on one side of the mounting platform 1. A pressure pump 2 for pressurizing natural gas is embedded in the mounting platform 1. The pressure pump 2 and the gas supply bottle 3 are connected to each other and communicated with the first transport pipeline 4. A second transport pipeline 401 is installed on the mounting platform 1 by bolt connection. One end of the second transport pipeline 401 is connected to and communicated with the pressure pump 2. A gas storage bottle 6 for pressurized natural gas is placed on the other side of the mounting platform 1. The other end of the second transport pipeline 401 is connected to and communicated with the gas cylinder 6. A manual valve 5 for controlling the flow of natural gas is rotatably provided on the second transport pipeline 401. It also includes a natural gas sensor 7, a third transport pipeline 8, an exhaust fan 9 and an alarm 10. Two natural gas sensors 7 are installed on the mounting platform 1 by bolt connection. The side of the natural gas sensor 7 is connected to and communicated with the third transport pipeline 8. The exhaust fan 9 is embedded in the third transport pipeline 8. The side of the natural gas sensor 7 is installed with an alarm 10 by bolt connection. The alarm 10 is electrically connected to the natural gas sensor 7.

[0025] When it is necessary to sample and pressurize the natural gas, first place the gas supply bottle 3 containing the natural gas on the mounting platform 1 and connect it to the first transport pipeline 4, then open the gas supply bottle 3, and the natural gas in the gas supply bottle 3 enters the pressure pump 2 through the first transport pipeline 4, and the natural gas is pressurized by starting the pressure pump 2, and then the pressurized natural gas enters the second transport pipeline 401, and the empty gas storage bottle 6 is placed on the mounting platform 1 and connected to the second transport pipeline 401, and then the manual valve 5 is opened by turning to allow the pressurized natural gas to enter the gas storage bottle 6 for collection; when it is necessary to detect whether the natural gas is leaking, the air is sucked into the third transport pipeline 8 by starting the exhaust fan 9, and when the air contains natural gas components, the natural gas sensor 7 will detect the natural gas, and then send a signal to the alarm 10, so that the alarm 10 will sound an alarm to prompt the staff to handle and repair it in time.

[0026] Example 2: Based on Example 1, refer to Figure 4 As shown, it also includes two flow pipes 11 connected and communicated on both sides of the first transport pipe 4, both ends of the flow pipe 11 are in circulation with the first transport pipe 4, two guide rods 17 are fixedly connected on both sides of the first transport pipe 4 by welding, and a stopper 16 for separating the first transport pipe 4 and the flow pipe 11 is slidably provided on the two guide rods 17 on the same side, and a second elastic member 18 is wound around the guide rod 17, and the second elastic member 18 pushes the stopper 16 to block both ends of the flow pipe 11, and both sides of the first transport pipe 4 are connected and communicated with a connecting tube 13, and a through hole for exhaust is opened at one end of the connecting tube 13 away from the first transport pipe 4, and a pressing plate 1201 is slidably provided in the connecting tube 13, and a first elastic member 14 is fixedly connected between the pressing plate 1201 and the connecting tube 13 by welding, a first wedge block 12 is fixedly connected to the pressing plate 1201 by welding, and a second wedge block 15 is fixedly connected to the stopper 16 by welding, and the first wedge block 12 and the second wedge block 15 cooperate with each other.

[0027] When the natural gas enters the second transportation pipeline 401 after being pressurized by the pressure pump 2, if the natural gas is over-pressurized, the natural gas in the second transportation pipeline 401 will push the pressure plates 1201 on both sides to slide along the connecting tube 13 to the side away from each other. At this time, the first elastic member 14 is compressed and deformed by the force, and at the same time, the pressure plate 1201 drives the first wedge block 12 to push the second wedge block 15, so that the second wedge block 15 drives the stopper 16 to slide along the two guide rods 17 and compress the second elastic member 18. At this time, the stopper 16 is away from the circulation pipe 11, so that the circulation pipe 11 is connected with the second transportation pipeline 401. At this time, the high-pressure natural gas in the second transportation pipeline 401 enters the circulation pipe 11 and is automatically depressurized.

[0028] See also Figure 5As shown, it also includes a mounting frame 19 installed on the mounting platform 1 by bolt connection, a worm 20 is rotatably arranged on the mounting frame 19, a threaded adjustment rod 21 is transversely slidably arranged on the mounting frame 19, the threaded adjustment rod 21 is threadedly connected to the worm 20, and a clamping block 2101 for clamping the gas cylinder 6 is fixed to the threaded adjustment rod 21 by welding.

[0029] When pressurized natural gas needs to be poured into the gas cylinder 6, in order to prevent the gas cylinder 6 from shaking, the worm 20 is rotated to engage with the threaded adjustment rod 21, and the threaded adjustment rod 21 drives the clamping block 2101 to slide along the mounting frame 19 and approach the gas cylinder 6. The gas cylinder 6 is clamped and fixed by the clamping block 2101 and the mounting frame 19. When the gas cylinder 6 is filled with natural gas, the worm 20 is rotated in the opposite direction to loosen the gas cylinder 6 by the clamping block 2101 and the mounting frame 19.

[0030] See also Figure 5 and Figure 6 As shown, it also includes three connecting pipes 22 fixedly connected to the bottom of the first transport pipeline 4 by bolt connection, and a conductive tube 23 is fixedly connected to the bottom of the connecting pipe 22 by welding. A plurality of diodes 24 for conducting static electricity are fixedly connected in the conductive tube 23 by welding, and the lower end of the diode 24 is connected to the ground. A rubber disc 25 is installed at the bottom of the conductive tube 23 by bonding.

[0031] When static electricity is generated on the second transport pipeline 401, it is easy to cause electric sparks inside, which may lead to an explosion. At this time, the static electricity is transmitted to the connecting pipe 22, and the static electricity enters the diode 24 in the conductive tube 23 through the connecting pipe 22. The diode 24 transmits the static electricity to the ground, thereby eliminating the static electricity on the second transport pipeline 401. The rubber disc 25 can prevent the static electricity on the diode 24 from being transmitted to the mounting platform 1.
