Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas meter technology, specifically to a valve core structure for an anti-clogging industrial gas meter. Background Technology
[0002] Industrial gas meters are specialized devices used to accumulate the total amount of industrial gas (such as natural gas, liquefied gas, etc.) passing through pipelines within a specific time period. In industrial gas meters, the valve core structure is the core component for achieving accurate flow regulation and measurement, and its design directly affects the accuracy and stability of the meter.
[0003] In the process of industrial gas metering, industrial gas usually contains a certain amount of solid particles, oil stains and other impurities. These impurities tend to accumulate at the valve core during the gas flow. Specifically, when gas passes through the valve core, larger solid particles will get stuck in the gaps of the valve core or between moving parts, hindering the normal movement of the valve core. This will cause the valve core to be unable to accurately regulate the gas flow, thus causing the metering results to deviate. Utility Model Content
[0004] This utility model provides a valve core structure for an anti-clogging industrial gas meter. The filter cartridge in the filtration mechanism can initially filter out larger particulate impurities in the gas, preventing these impurities from directly entering the valve core body and causing blockage. At the same time, the driving component drives the rotating cylinder to rotate, causing the filter cartridge to rotate together. This allows the impurities to be evenly dispersed in the filter cartridge under the action of centrifugal force, preventing impurities from accumulating at the bottom of the filter cartridge and further improving the filtration capacity and service life of the filter cartridge. In addition, the filter element in the filtration component can perform fine filtration of the gas, effectively removing tiny impurities in the gas, thereby solving the problem of valve core blockage.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a valve core structure for an anti-clogging industrial gas meter, comprising:
[0006] Meter housing;
[0007] The valve core body is installed on one side of the inner wall of the meter housing;
[0008] The air intake pipe is installed on one side of the outer wall of the valve core body;
[0009] A filtering mechanism is located between the air intake pipe and the valve core body. The filtering mechanism includes a rotating cylinder, a driving component, a filter cylinder, and a filter component. One end of the rotating cylinder is rotatably embedded in the outer wall of the valve core body, and the other end of the rotating cylinder is rotatably embedded in the outer wall of the air intake pipe. The driving component is located on the rotating cylinder, the filter cylinder is fixedly installed on the inner wall of the rotating cylinder, and the filter component is located inside the rotating cylinder.
[0010] Furthermore, the driving component includes a support frame and a driving assembly. The support frame is fixedly disposed on one side of the outer wall of the meter housing, the driving assembly is disposed on the support frame, and the rotating cylinder is rotatably embedded in the top of the outer wall of the support frame.
[0011] Furthermore, the drive assembly includes a servo motor, a pinion gear, and a large gear. The servo motor is bolted to the top of the outer wall of the support frame. The pinion gear is fixedly sleeved on the output end of the servo motor. The large gear is movably sleeved on the outer wall of the rotating cylinder, and the large gear meshes with the pinion gear.
[0012] Furthermore, the filter component includes an mounting cylinder and a filter element, wherein the mounting cylinder is threadedly connected to the inner wall of the rotating cylinder, and the filter element is fixedly disposed on the inner wall of the mounting cylinder.
[0013] Furthermore, a suction pipe is fixedly embedded on one side of the outer wall of the air intake pipe, and the suction pipe extends to the inner wall of the filter cartridge.
[0014] Furthermore, a dust collection device is installed on one side of the inner wall of the meter housing, and one end of the dust collection pipe is installed at the input end of the dust collection device.
[0015] This invention provides a valve core structure for an anti-clogging industrial gas meter. It offers the following advantages: The valve core structure, through a filter cartridge in the filtration mechanism, can initially filter out larger particulate impurities in the gas, preventing these impurities from directly entering the valve core body and causing blockage. Simultaneously, the driving component drives the rotating cylinder to rotate, causing the filter cartridge to rotate as well. This allows impurities to be evenly dispersed within the filter cartridge under centrifugal force, preventing impurities from accumulating at the bottom of the filter cartridge and further improving the filtration capacity and service life of the filter cartridge.

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0021] Please see Figure 1-3 This utility model provides a technical solution: a valve core structure for an anti-clogging industrial gas meter, comprising:
[0022] Meter housing 1;
[0023] The valve core body 2 is installed on one side of the inner wall of the meter housing 1;
[0024] The intake pipe 3 is installed on one side of the outer wall of the valve core body 2;
[0025] The filter mechanism 4 is located between the air intake pipe 3 and the valve core body 2. The filter mechanism 4 includes a rotating cylinder 401, a driving component, a filter cylinder 402, and a filter component. One end of the rotating cylinder 401 is rotatably embedded in the outer wall of the valve core body 2, and the other end of the rotating cylinder 401 is rotatably embedded in the outer wall of the air intake pipe 3. The driving component is located on the rotating cylinder 401, the filter cylinder 402 is fixedly installed on the inner wall of the rotating cylinder 401, and the filter component is located inside the rotating cylinder 401.
[0026] In this implementation scheme: the meter housing 1 is the external protective structure of the entire meter, the valve core body 2 is the core control component of the meter, which regulates the flow of gas through its own movement, and can achieve precise control of gas metering. Through the air inlet pipe 3, external industrial gas can be introduced into the meter, providing a gas source for subsequent metering and filtration. Through the filter mechanism 4, the gas entering the valve core body 2 can be filtered to remove solid particles, oil and other impurities from the gas, improve the cleanliness of the gas, and prevent these impurities from entering the valve core body 2 and causing blockage. The drive component drives the rotating cylinder 401 to rotate on the air inlet pipe 3 of the valve core body 2, which can drive the filter cylinder 402 to rotate, so that the impurities are dispersed in the filter cylinder 402, avoiding the accumulation of large particles of impurities filtered by the filter cylinder 402 at the bottom of the filter cylinder 402, which would affect the filtration effect. Through the filter component, the gas can be further finely filtered to further remove tiny impurities in the gas.
[0027] Specifically, the driving component includes a support frame 403 and a driving assembly. The support frame 403 is fixedly installed on one side of the outer wall of the meter housing 1, the driving assembly is installed on the support frame 403, and the rotating cylinder 401 is rotatably embedded in the top of the outer wall of the support frame 403.
[0028] In this embodiment: the support frame 403 provides a mounting base for the drive assembly, and the drive assembly is used to drive the rotating cylinder 401 to rotate.
[0029] Specifically, the drive components include a servo motor 404, a pinion 405, and a gear 406. The servo motor 404 is bolted to the top of the outer wall of the support frame 403. The pinion 405 is fixedly sleeved on the output end of the servo motor 404. The gear 406 is movably sleeved on the outer wall of the rotating cylinder 401, and the gear 406 meshes with the pinion 405.
[0030] In this embodiment: the servo motor 404 provides power, and through the transmission of the pinion 405 and the gear 406, it can drive the rotating cylinder 401 to rotate, which avoids the accumulation of impurities after filtration on the filter cylinder 402, thus affecting the filtration effect and improving the filtration effect.
[0031] Specifically, the filter components include a mounting cylinder 407 and a filter element 408. The mounting cylinder 407 is threadedly connected to the inner wall of the rotating cylinder 401, and the filter element 408 is fixedly disposed on the inner wall of the mounting cylinder 407.
[0032] In this embodiment: the mounting cylinder 407 is used for the installation and placement of the filter element 408. The filter element 408 can effectively filter out tiny impurities, making the gas cleaner, thereby protecting the valve core body 2 and preventing impurities from entering the valve core body 2 and causing blockage.
[0033] Specifically, a suction pipe 5 is fixedly embedded on one side of the outer wall of the air intake pipe 3, and the suction pipe 5 extends to the inner wall of the filter cartridge 402.
[0034] In this embodiment: the suction pipe 5 can suck out the impurities collected in the filter cartridge 402, clean the impurities in the filter cartridge 402 in time, and prevent the accumulation of impurities from affecting the filtration effect and the flow of gas.

[0036] In this embodiment: the vacuuming device 6 provides suction power, and the vacuuming pipe 5 sucks out the impurities in the filter cartridge 402 and discharges them to the outside of the meter.
[0037] In use, the servo motor 404 is started, which drives the pinion 405 to rotate. The pinion 405, through meshing with the large gear 406, drives the rotating cylinder 401 to rotate. Industrial gas enters the meter from the inlet pipe 3 and first passes through the filter cylinder 402 in the rotating cylinder 401. Under the rotation of the rotating cylinder 401, impurities are prevented from accumulating in the filter cylinder 402. At the same time, the filter element 408 performs fine filtration of the gas, further removing tiny impurities. The dust collection device 6 is started, and the impurities collected in the filter cylinder 402 are sucked out through the dust collection pipe 5 and discharged outside the meter, keeping the filter cylinder 402 clean and preventing excessive accumulation of impurities from affecting the filtration effect and the flow of gas.
