Description

Technical Field

[0001] This utility model relates to the field of gas detection technology, and in particular to a sampling structure for gas production detection. Background Technology

[0002] Gas detection in the gas production process enables real-time monitoring of gas composition and concentration in the production environment, thereby promptly identifying potential safety hazards. This not only ensures compliance of the production process and protects workers from toxic and harmful gases, but also prevents accidents such as fires and explosions caused by gas leaks or accumulation. At the same time, through gas detection, enterprises can also optimize production processes, improve product quality, reduce waste gas emissions, and achieve green production.

[0003] Currently, when sampling for gas detection, the sampling equipment needs to be connected to the gas production equipment through a sampling tube. During detection, if there is air in the sampling tube, the gas being tested will mix with the air because the air in the sampling tube is not completely expelled, which will reduce the gas concentration and make the detection results inaccurate.

[0004] Furthermore, by connecting the sampling tube to the gas production equipment, it is impossible to directly assess the gas sampling seal during sampling. When a gas leak occurs, there is no warning or alert; the leak can only be detected after the odor has dissipated, resulting in poor sampling safety.

[0005] Therefore, this application provides a sampling structure for gas production detection to meet the requirements. Utility Model Content

[0006] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a sampling structure for gas production detection.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A sampling structure for gas production detection includes: a sampling tube, a connector, a control valve, an exhaust pipe, an exhaust nozzle, a push rod, a piston, a sealing sleeve, a monitoring tube, a sealing plug, a connecting hose, and a monitoring block. The sampling tube has connectors installed at both ends. A control valve is installed on the pipe of the sampling tube. The sampling tube is installed on the side of the exhaust pipe, and a connection port is provided on the side of the exhaust pipe. An exhaust nozzle is installed at the front end of the exhaust pipe, and a push rod is installed at the rear end of the exhaust pipe. A vent is provided on the surface of the push rod, and a piston is installed at one end of the push rod. A sealing sleeve is installed on the outer end of one side of the connector. A monitoring tube is installed on the side of the sealing sleeve, and a sealing plug is installed at the opening of the monitoring tube. A connecting hose is installed inside the monitoring tube, and a monitoring block is installed at the other end of the connecting hose.

[0009] Preferably, the sampling tube is divided into two sections, and the two sections are connected to the exhaust pipe through connection ports.

[0010] Preferably, one end of the push rod extends into the interior of the exhaust pipe, and the push rod and the exhaust pipe are movably connected.

[0011] Preferably, the connection port is located at the tail end of the exhaust pipe, and the piston is located inside the exhaust pipe.

[0012] Preferably, the vent is located at the tail of the push rod, and the vent extends through the push rod from one side of the push rod to the other side of the push rod.

[0013] Preferably, when the push rod is fully pushed into the exhaust pipe, the vent and the connection port are aligned on the same axis.

[0014] Preferably, the sealing sleeve is nested at the outer end of the joint, and the monitoring tube is located at the outer end of the side of the connection seam between the sealing sleeve and the joint.

[0015] Preferably, the monitoring tube is made of transparent acrylic material, and the monitoring block is connected to the sealing sleeve through a connecting hose and a sealing plug.

[0016] Preferably, the monitoring tube is filled with water, and the monitoring block is spherical with several sets of circular through holes on its surface.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] 1. Before sampling, push the push rod fully into the exhaust pipe. The push rod and piston will expel any residual air from the exhaust pipe and sampling tube through the exhaust port. The sampling gas from the sampling tube can then pass through the connection port into the sampling tube at the other end, ensuring the accuracy of the sampling. 2. By nesting a sealing sleeve at the outer end of the connector, and placing the monitoring tube at the outer side of the connection between the sealing sleeve and the connector, the sealing of the connection between the sealing sleeve and the connector can be detected. This allows for an assessment of the sealing performance of the connection with the sampling equipment. Leaked gas passes through the sealing plug and connecting hose from the sealing sleeve into the monitoring block inside the monitoring tube. The gas can then exit through the circular through-hole of the monitoring block. The presence or absence of air bubbles in the water inside the monitoring tube indicates whether the sealing sleeve and connector are leaking, providing a direct understanding of the gas sampling seal and making the sampling process safer.

Detailed Implementation

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides a sampling structure for gas production detection, comprising: a sampling tube 1, a connector 2, a control valve 3, an exhaust pipe 4, an exhaust nozzle 5, a push rod 6, a piston 7, a sealing sleeve 8, a monitoring tube 9, a sealing plug 10, a connecting hose 11, and a monitoring block 12. The sampling tube 1 is fitted with connectors 2 at both ends. A control valve 3 is installed on the pipe of the sampling tube 1. The sampling tube 1 is installed on the side of the exhaust pipe 4. A connection port 401 is provided on the side of the exhaust pipe 4. An exhaust nozzle 5 is installed at the front end of the exhaust pipe 4. A push rod 6 is installed at the rear end of the exhaust pipe 4. A vent 601 is provided on the surface of the push rod 6. A piston 7 is installed at one end of the push rod 6. A sealing sleeve 8 is installed on the outer end of one side of the connector 2. A monitoring tube 9 is installed on the side of the sealing sleeve 8. A sealing plug 10 is installed at the opening of the monitoring tube 9. A connecting hose 11 is installed inside the monitoring tube 9. A monitoring block 12 is installed at the other end of the connecting hose 11.

[0028] In this embodiment, the sampling tube 1 is divided into two sections, and the two sections of the sampling tube 1 are respectively connected to the exhaust pipe 4 through the connection port 401.

[0029] In this embodiment, one end of the push rod 6 extends into the interior of the exhaust pipe 4, and the push rod 6 and the exhaust pipe 4 are movably connected.

[0030] In this embodiment, the connection port 401 is located at the tail of the exhaust pipe 4, and the piston 7 is located inside the exhaust pipe 4.

[0031] In this embodiment, the vent 601 is located at the tail of the push rod 6, and the vent 601 extends through the push rod 6 from one side of the push rod 6 to the other side of the push rod 6. After the push rod 6 is pushed in, the vent 601 is sent into the exhaust pipe 4. After the push rod 6 is pulled out, the push rod 6 blocks and seals the two sampling tubes 1.

[0032] In this embodiment, when the push rod 6 is fully pushed into the exhaust pipe 4, the vent 601 and the connection port 401 are aligned on the same axis. After the push rod 6 is fully pushed into the exhaust pipe 4, the air remaining in the exhaust pipe 4 and the sampling tube 1 can be discharged from the exhaust nozzle 5 through the push rod 6 and the piston 7. The sampling gas of the sampling tube 1 can be introduced into the sampling tube 1 at the other end through the connection port 401, thereby ensuring the accuracy of sampling.

[0033] In this embodiment, the sealing sleeve 8 is nested at the outer end of the connector 2, and the monitoring tube 9 is located at the outer end of the side of the connection seam between the sealing sleeve 8 and the connector 2, which can detect whether the connection seam between the sealing sleeve 8 and the connector 2 is sealed, thereby understanding the sealing performance of the connection with the sampling device.

[0034] In this embodiment, the monitoring tube 9 is made of transparent acrylic material, and the monitoring block 12 is connected to the sealing sleeve 8 through the connecting hose 11 and the sealing plug 10. The monitoring tube 9 made of transparent acrylic material is convenient for observation. The leaked gas is introduced from the sealing sleeve 8 through the sealing plug 10 and the connecting hose 11 into the monitoring block 12 inside the monitoring tube 9.

[0035] In this embodiment, water is injected into the monitoring tube 9, and the monitoring block 12 is spherical. Several sets of circular through holes are provided on the surface of the monitoring block 12. Gas can be discharged from the circular through holes of the monitoring block 12. Whether or not air bubbles appear in the water inside the monitoring tube 9 can be used to determine whether the sealing sleeve 8 and the connector 2 are leaking, so as to intuitively understand the sealing performance of the gas sampling.
