Description

Technical Field

[0001] This application relates to the field of pressure regulating valve technology, specifically a high-sealing gas pressure regulating valve. Background Technology

[0002] Gas pressure regulating valves (also known as pressure reducing valves or pressure stabilizing valves) are devices used to regulate gas pressure, and are mainly made of chrome-plated copper, brass, and stainless steel. They are widely used in industrial gases and scientific research fields, and can affect experimental data and production safety. The working principle of a pressure regulating valve is to receive control signals to adjust the valve and control parameters such as the flow rate, temperature, and pressure of the medium in the pipeline.

[0003] For example, the patent with publication number CN221482778U discloses a methanol pressure regulating valve. It uses a backflushing component to backflush the filter layer and a guide plate to scrape the filter layer. At the same time, the conical ring can position impurities in the internal area, thereby avoiding the suspension of impurities. This allows the filter layer to maintain its filtering function and reduces the impact of more internal impurities, thus ensuring the normal use of the pressure regulating valve housing.

[0004] In the aforementioned patent, the device increases filtration efficiency by setting up a filter assembly and scraping the filter layer with a guide plate. However, this filtration method causes impurities and dirt to fall onto the cup wall outside the filter layer. Over time, a large amount of dirt will adhere to the cup wall. Furthermore, since the cup wall of the filter assembly is relatively deep, it may be inconvenient to clean it from the inside. Therefore, it is necessary to provide a high-sealing gas pressure regulating valve that can be cleaned quickly to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a high-sealing gas pressure regulating valve that can quickly clean the filter tank at the bottom of the pressure regulating valve.

[0007] The technical solution adopted by this application to solve its technical problem is: a high-sealing gas pressure regulating valve, including a pressure regulating valve, a filter provided at the bottom of the pressure regulating valve; a cleaning assembly, the cleaning assembly including a connecting cup, the connecting cup being threadedly installed on the outside of the filter, the connecting cup having a receiving cavity inside, a through hole provided at the bottom of the receiving cavity, a collecting dish provided inside the receiving cavity, a connecting tube extending from the bottom of the collecting dish, the size of the connecting tube being adapted to the size of the through hole; and a locking buckle threadedly installed on the bottom of the connecting cup outside the through hole.

[0008] Furthermore, the top of the collection dish is provided with a beveled chamfer.

[0009] Furthermore, a plugging block is threaded onto the bottom of the connecting pipe, the plugging block being used to seal the connecting pipe.

[0010] Furthermore, a pressure regulating knob is provided on the top of the pressure regulating valve, and a pressure gauge is provided on the outside of the pressure regulating valve.

[0011] Furthermore, an air inlet is provided on one side of the pressure regulating valve, and an air outlet is provided on the other side of the pressure regulating valve.

[0012] The beneficial effects of this application are: The high-sealing gas pressure regulating valve provided by this application, by setting a cleaning component, enables the waste liquid in the connecting cup at the bottom of the regulating valve to be cleaned quickly and thoroughly, which not only improves the cleaning efficiency of the device, avoids problems such as corrosion and blockage caused by waste liquid retention, but also extends the service life of the device.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0023] like Figures 1-2 As shown, this application provides a high-sealing gas pressure regulating valve, including a pressure regulating valve 1. The pressure regulating valve 1 has a valve body 11, and an air inlet 12 is provided on one side of the valve body 11. The air inlet 12 is connected to an external high-pressure gas pipeline for inputting high-pressure gas into the valve body 11. At the same time, a pressure regulating knob 15 is provided on the top of the valve body 11 for controlling the pressure of the high-pressure gas flowing inside the valve body 11. Meanwhile, a pressure gauge 14 is provided on the outside of the valve body 11, which allows the operator to intuitively and accurately observe the pressure status of the gas path.

[0024] Meanwhile, a filter 2 is fixedly installed at the bottom of the valve body 11. A cleaning component 3 is provided on the outside of the filter 2. The cleaning component 3 includes a connecting cup 31, which is threadedly installed at the bottom of the valve body 11 on the outside of the filter 2. It is used to filter the high-pressure air entering through the air inlet 12. At the same time, an air outlet 13 is provided on the other side of the valve body 11. The air outlet 13 is connected to an external air outlet pipe and is used to discharge clean air to the outside.

[0025] When compressed gas enters valve body 11, it first passes through filter 2. Then, due to the guidance of the baffle plate in filter 2, it rotates strongly. Under the action of centrifugal force, large solid impurities and liquid water droplets in the compressed air are thrown onto the cup wall of connecting cup 31 and deposited at the bottom of the cup wall under the action of gravity. Then, the purified air is discharged from the outlet 13.

[0026] like Figures 2-3 As shown, the connecting cup 31 has a receiving cavity inside, and a through hole 32 is provided at the bottom of the receiving cavity. A collecting dish 33 is provided inside the receiving cavity, and a connecting tube 34 extends from the bottom of the collecting dish 33. The size of the connecting tube 34 is adapted to the size of the through hole 32, so that the connecting tube 34 is suitable for sliding inside the through hole 32. At the same time, a blocking block 4 is threaded on the bottom of the connecting tube 34. The blocking block 4 is used to seal the connecting tube 34 to prevent waste liquid leakage.

[0027] Meanwhile, a chamfer 35 is provided on the top of the collecting dish 33. This chamfer 35 allows the droplets to slide directly into the inside of the collecting dish 33 when they drip down to the bottom of the connecting cup 31, avoiding the residue of the droplets on the cup wall. At the same time, a locking buckle 5 is threadedly installed on the outside of the through hole 32 at the bottom of the connecting cup 31. The locking buckle 5 is used to firmly lock the connecting tube 34 to the bottom of the connecting cup 31, ensuring the stability and sealing of the collecting dish 33.

[0028] When the cleaning component 3 needs to be cleaned after a long period of filtration, first remove the connecting cup 31 from the bottom of the filter 2, and then open the lock 5, so that the operator can move the collecting dish 33 to the opening at the top of the connecting cup 31 through the connecting tube 34. At this time, the impurities and droplets attached to the surface of the cup will come into contact with the collecting dish 33 and enter the interior of the collecting dish 33. After the dirt attached to the cup wall is removed, the block 4 can be opened, so that the waste liquid accumulated inside the collecting dish 33 flows out from the bottom of the connecting tube 34. At this time, a simple cleaning of the collecting dish 33 and the connecting cup 31 can complete the cleaning work, which improves the cleaning efficiency of the device.

[0029] In summary, by incorporating the cleaning component 3, this device enables the waste liquid in the connecting cup 31 at the bottom of the regulating valve 1 to be cleaned quickly and thoroughly. This not only improves the cleaning efficiency of the device and avoids problems such as corrosion and blockage caused by waste liquid retention, but also extends the service life of the device.

[0030] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
