Description

Technical Field

[0001] This utility model relates to the field of gas sampling equipment technology, specifically a gas sampling equipment with leak-proof function. Background Technology

[0002] Gas sampling refers to the process of collecting gas samples from the atmospheric environment or working environment. This is very important for environmental monitoring, industrial production process control, and scientific research. Gas samplers are routine instruments used to perform this task. They can collect two gas samples simultaneously or collect balanced samples. The sampling work is fast and reliable. Gas samplers are widely used in metallurgy, mining, chemical industry, construction, casting, power, environmental monitoring, health and epidemic prevention and other departments. Therefore, a gas sampling device with leakage prevention function is needed.

[0003] In existing technologies, gas sampling equipment may suffer from problems such as poor sealing of the interface leading to gas leakage that affects sampling accuracy, and gas leakage that can easily occur due to vibration during movement or transportation. Utility Model Content

[0004] The purpose of this invention is to provide a gas sampling device with leak-proof function, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas sampling device with leak-proof function, including a fixing plate,

[0006] Support legs fixedly installed on the top of the fixed plate;

[0007] The collection tank body is fixedly installed on top of the support leg;

[0008] And a collection assembly located at the top of the fixed plate;

[0009] The collection assembly includes a collection mechanism disposed at the top of the fixed plate;

[0010] An auxiliary mechanism is provided on the side wall of the collection tank body, and the auxiliary mechanism is connected to the collection mechanism.

[0011] Preferably, there are four support legs, all of which are of the same shape and size. The four support legs are fixedly installed on the top of the fixing plate, and the support legs can support the position of the collection tank body.

[0012] Preferably, the collection mechanism includes a connecting pipe, which is fixedly installed on the side wall of the collection tank body. An air inlet pipe is fixedly installed on the top of the connecting pipe, and a threaded rod is installed on the inner wall of the air inlet pipe. An adjusting valve core is rotatably installed on the bottom of the threaded rod through a bearing. When the threaded rod rotates, it can drive the position of the adjusting valve core to move.

[0013] Preferably, the side wall of the regulating valve core is slidably connected to the inner wall of the intake pipe, and the side wall of the regulating valve core is in contact with the inner wall of the connecting pipe.

[0014] Preferably, the side wall of the threaded rod is threadedly connected to the inner wall of the air intake pipe, and a turntable is fixedly installed on the top of the threaded rod.

[0015] Preferably, the auxiliary mechanism includes a side plate, the side wall of which is fixedly connected to the side wall of the connecting pipe, a connecting block is rotatably mounted on the inner wall of the side plate via a bearing, a baffle is fixedly mounted on the other end of the connecting block, and a sealing gasket is fixedly mounted on the side wall of the baffle.

[0016] Preferably, the sidewall diameter of the sealing gasket is the same as the inner wall diameter of the connecting pipe, the sidewall of the sealing gasket is slidably connected to the inner wall of the connecting pipe, and the sidewall of the baffle is in contact with the sidewall of the connecting pipe.

[0017] This invention provides a gas sampling device with leak-proof function. It has the following beneficial effects:

[0018] (1) When the operator needs to collect gas, the turntable can be rotated, which drives the threaded rod to rotate. The side wall of the threaded rod is threadedly connected to the inner wall of the air inlet pipe. Therefore, when the threaded rod rotates, it can drive the position of the regulating valve core to rise. When the bottom of the regulating valve core does not contact the inner wall of the connecting pipe and moves into the air inlet pipe, the gas will enter the inner wall of the collection tank body through the connecting pipe, which is convenient for the operator to collect the gas. Then the operator rotates the turntable in the opposite direction, and the turntable drives the position of the threaded rod and the regulating valve core to fall. When the bottom of the regulating valve core enters the inner wall of the connecting pipe, the gas can be sealed. In the prior art, the gas sampling equipment interface is not sealed tightly, which leads to gas leakage and affects the sampling accuracy. During movement or transportation, the gas is easily escaped due to vibration.

[0019] (2) The operator can also rotate the position of the baffle. The baffle rotates on the inner wall of the side plate through the connecting block. When the baffle rotates, it can effectively drive the sealing gasket into the inner wall of the connecting pipe, improve the sealing of the inner wall of the connecting pipe, prevent gas damage and leakage, and make it easier for the operator to use the device.

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0027] Example 1: A preferred embodiment of the gas sampling device with leak-proof function provided by this utility model is as follows: Figures 1 to 5 As shown: A gas sampling device with leak-proof function, including a fixing plate 1,

[0028] Support leg 2 is fixedly installed on the top of the fixed plate 1;

[0029] The collection tank body 3 is fixedly installed on the top of the support leg 2;

[0030] And the collection component 4 is located at the top of the fixed plate 1;

[0031] The collection component 4 includes a collection mechanism 41 disposed at the top of the fixed plate 1;

[0032] An auxiliary mechanism 42 is provided on the side wall of the collection tank body 3, and the auxiliary mechanism 42 is connected to the collection mechanism 41.

[0033] There are four support legs 2, all of which are the same size and shape. The four support legs 2 are fixedly installed on the top of the fixed plate 1, and the position of the collection tank body 3 can be supported by the support legs 2.

[0034] The collection mechanism 41 includes a connecting pipe 412, which is fixedly installed on the side wall of the collection tank body 3. An air inlet pipe 411 is fixedly installed on the top of the connecting pipe 412. A threaded rod 414 is installed on the inner wall of the air inlet pipe 411. An adjusting valve core 415 is rotatably installed on the bottom of the threaded rod 414 through a bearing. When the threaded rod 414 rotates, it can drive the position of the adjusting valve core 415 to move.

[0035] In this embodiment, the side wall of the regulating valve core 415 is slidably connected to the inner wall of the air intake pipe 411, and the side wall of the regulating valve core 415 is in contact with the inner wall of the connecting pipe 412.

[0036] Furthermore, the side wall of the threaded rod 414 is threadedly connected to the inner wall of the intake pipe 411, and a turntable 413 is fixedly installed on the top of the threaded rod 414.

[0037] In the specific implementation process, when the operator needs to collect gas, the turntable 413 can be rotated. The turntable 413 drives the threaded rod 414 to rotate. The side wall of the threaded rod 414 is threadedly connected to the inner wall of the air inlet pipe 411. Therefore, when the threaded rod 414 rotates, it can drive the position of the regulating valve core 415 to rise. When the bottom of the regulating valve core 415 is not in contact with the inner wall of the connecting pipe 412 and moves into the air inlet pipe 411, the gas will enter the inner wall of the collection tank body 3 through the connecting pipe 412, making it convenient for the operator to collect the gas. Then, the operator rotates the turntable 413 in the opposite direction. The turntable 413 drives the threaded rod 414 and the regulating valve core 415 to fall, so that when the bottom of the regulating valve core 415 enters the inner wall of the connecting pipe 412, the gas can be sealed.

[0038] Example 2: Based on Example 1, a preferred embodiment of the gas sampling device with leak-proof function provided by this utility model is as follows: Figures 1 to 5 As shown: The auxiliary mechanism 42 includes a side plate 421. The side wall of the side plate 421 is fixedly connected to the side wall of the connecting pipe 412. A connecting block 422 is rotatably mounted on the inner wall of the side plate 421 through a bearing. A baffle 423 is fixedly mounted on the other end of the connecting block 422. A sealing gasket 424 is fixedly mounted on the side wall of the baffle 423.

[0039] In this embodiment, the side wall diameter of the sealing gasket 424 is the same as the inner wall diameter of the connecting pipe 412, the side wall of the sealing gasket 424 is slidably connected to the inner wall of the connecting pipe 412, and the side wall of the baffle 423 is in contact with the side wall of the connecting pipe 412.

[0040] In the specific implementation process, the operator can also rotate the position of the baffle 423. The baffle 423 rotates on the inner wall of the side plate 421 through the connecting block 422. When the baffle 423 rotates, it can effectively drive the sealing gasket 424 into the inner wall of the connecting pipe 412, improve the sealing of the inner wall of the connecting pipe 412, and prevent gas damage and leakage.

[0041] 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 the 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.
