[0001] This utility model relates to the field of high-pressure gas pressure reduction technology, specifically to an adjustable high-pressure gas pressure reduction device. Background Technology

[0002] In industries such as cleanrooms, microbial testing, and pharmaceuticals, high-pressure diffusion devices are used to assist in detecting the cleanliness and microbial content of compressed air in cleanrooms, ensuring compliance with GMP requirements. However, because the flow rate of the high-pressure gas is constant, and the high-pressure diffusion device itself generally cannot adjust the flow rate, requiring an external specialized adjustment device, it cannot quickly and effectively meet the needs of some testing instruments. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable high-pressure gas pressure reducing device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable high-pressure gas pressure reducing device, comprising a throttle valve body and a pressurization chamber body, wherein the throttle valve body and the pressurization chamber body are connected by a first pressure reducing pipe; a throttle valve hollow column is installed inside the throttle valve body, and a throttle valve pin is vertically slidably connected inside the throttle valve body, the throttle valve pin being slidably connected to the throttle valve hollow column, and a driving part for driving the throttle valve pin to slide is provided on the throttle valve body; a second pressure reducing pipe is installed on the pressurization chamber body, and the first pressure reducing pipe and the second pressure reducing pipe are in communication.

[0005] Furthermore, the drive unit includes a throttle valve cover mounted on the throttle valve body, a throttle valve pin threadedly connected to the throttle valve cover, and a knob mounted on the throttle valve pin.

[0006] Furthermore, a throttle valve top block is installed inside the throttle valve cover, and the throttle valve pin is slidably connected to the throttle valve top block; and a sealing gasket is provided between the throttle valve top block and the hollow column of the throttle valve.

[0007] Furthermore, a front connector is provided on one side of the throttle valve body, and an air intake quick connector is installed on the front connector.

[0008] Furthermore, a first sealing ring is provided between the throttle valve cover and the throttle valve body.

[0012] Furthermore, a rear connector is provided on the second pressure reducing pipe.

[0013] Furthermore, a front bracket is installed on the throttle valve body, and a rear bracket is installed on the pressurization chamber body.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: In actual use, when it is necessary to adjust the airflow according to the working environment, the throttle valve pin is driven by the drive unit to slide inside the hollow column, thus adjusting the vertical position of the throttle valve pin. This controls the gap between the throttle valve pin and the hollow column, thereby regulating the flow rate of compressed air. When the throttle valve pin is at its lowest point, the throttle valve is fully closed. The adjusted airflow enters the main body of the pressurization chamber through the first pressure reducing pipe, and then enters the external instrument through the second pressure reducing pipe, thus achieving the required pressure regulation. Therefore, through the above operation, users can more conveniently and effectively adjust the required high-pressure gas flow rate, improving work efficiency while reducing workload, resulting in better performance.

[0021] 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.

[0022] Please refer to Figures 1-4. This utility model provides a technical solution: an adjustable high-pressure gas pressure reducing device, including a throttle valve body 3 and a pressurization chamber body 17. The throttle valve body 3 and the pressurization chamber body 17 are connected by a first pressure reducing pipe 13. A throttle valve hollow column 11 is installed inside the throttle valve body 3, and a throttle valve pin 5 is vertically slidably connected inside the throttle valve body 3. The throttle valve pin 5 is slidably connected to the throttle valve hollow column 11, and a driving part for driving the throttle valve pin 5 to slide is provided on the throttle valve body 3. A second pressure reducing pipe 18 is installed on the pressurization chamber body 17, and the first pressure reducing pipe 13 and the second pressure reducing pipe 18 are in communication.

[0023] Specifically, the adjustable high-pressure gas pressure reducing device includes a throttle valve body 3 and a pressurization chamber body 17, which are connected by a first pressure reducing pipe 13. That is, gas entering from inside the throttle valve body 3 enters the pressurization chamber body 17 through the first pressure reducing pipe 13. It is known that the throttle valve body 3 has interconnected flow channels on both sides. A hollow throttle valve column 11 is installed inside the throttle valve body 3, and a throttle valve pin 5 is vertically slidably connected inside the throttle valve body 3. The throttle valve pin 5 is slidably connected to the hollow throttle valve column 11, and a driving part is provided on the throttle valve body 3 to drive the throttle valve pin 5 to slide. At this time, the driving part drives the throttle valve pin 5 to slide inside the throttle valve body 3, cooperating with the hollow throttle valve column 11 to adjust the airflow. The pressurization chamber body 17 is equipped with a second pressure-reducing pipe 18, and the first pressure-reducing pipe 13 is connected to the second pressure-reducing pipe 18. Gas passing through the throttle valve body 3 enters the pressurization chamber body 17 through the first pressure-reducing pipe 13, then re-enters the second pressure-reducing pipe 18, and finally enters the external instrument to achieve pressure regulation. In actual use, when the airflow needs to be adjusted according to the working environment, the drive unit drives the throttle valve pin 5 to slide inside the hollow column, adjusting the vertical position of the throttle valve pin 5. This controls the gap between the throttle valve pin 5 and the hollow column 11, regulating the flow rate of compressed air. When the throttle valve pin 5 is at its lowest point, the throttle valve is fully closed. The regulated airflow enters the pressurization chamber body 17 through the first pressure-reducing pipe 13 and then through the second pressure-reducing pipe 18, ultimately entering the external instrument to achieve pressure regulation. Therefore, through the above operations, users can more conveniently and effectively adjust the required high-pressure gas flow rate, improve work efficiency while reducing workload, and achieve better results.

[0024] In the embodiments provided by this utility model, the driving part includes a throttle valve cover 6 installed on the throttle valve body 3, a throttle valve pin 5 threadedly connected to the throttle valve cover 6, and a knob 4 installed on the throttle valve pin 5. When in use, when the knob 4 drives the throttle valve pin 5 to rotate, it will drive the throttle valve pin 5 to slide vertically on the throttle valve cover 6.

[0025] In the embodiments provided by this utility model, a throttle valve top block 7 is installed inside the throttle valve cover 6, and the throttle valve pin 5 is slidably connected to the throttle valve top block 7; and a sealing gasket 8 is provided between the throttle valve top block 7 and the throttle valve hollow column 11, thereby further improving the sealing performance and reducing leakage.

[0026] In the embodiments provided by this utility model, a front connector 2 is provided on one side of the throttle valve body 3, and an air inlet quick connector 1 is installed on the front connector 2 to facilitate air intake into the throttle valve body 3.

[0027] In the embodiments provided by this utility model, a first sealing ring 9 is provided between the throttle valve cover 6 and the throttle valve body 3, and a second sealing ring 10 is provided between the sealing gasket 8 and the throttle valve top block 7, which can improve the sealing performance.

[0029] In the embodiments provided by this utility model, a filter connector 16 is also provided on the pressurization chamber body 17, and a plurality of diffusion holes 21 are opened on the first pressure reducing pipe 13 so that the first pressure reducing pipe 13 and the filter connector 16 are connected. During operation, when compressed air enters the first pressure reducing pipe 13 after passing through the throttle valve body 3, part of the gas diffuses into the cavity of the pressure reducing chamber body through the diffusion holes 21 at the end of the first pressure reducing pipe 13, and then is discharged into the filter through the filter connector 16 at the top of the pressure reducing chamber body. Preferably, there are 24 diffusion holes 21.

[0030] In the embodiments provided by this utility model, the second pressure reducing pipe 18 is provided with a rear connector 20, which makes it more convenient to connect to external equipment.
