Description

Technical Field

[0001] This utility model relates to the field of pressure reducing valves, and more specifically, to a gas pressure reducing valve. Background Technology

[0002] A pressure reducing valve is a valve that reduces the inlet pressure to a desired outlet pressure by adjusting the inlet pressure and relies on the energy of the medium itself to automatically maintain a stable outlet pressure. A pressure reducing valve is a throttling element with variable local resistance. That is, by changing the throttling area, the flow velocity and kinetic energy of the fluid are changed, resulting in different pressure losses, thereby achieving the purpose of pressure reduction. However, existing pressure reducing valves usually only have one inlet port and one outlet port, making it inconvenient to meet the needs of simultaneous installation for multiple outlets.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a gas pressure reducing valve.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a gas pressure reducing valve, including a valve body, a plurality of output pipes connected to the outer peripheral wall of the valve body and communicating with the interior therein are fixedly connected, a sealing element for sealing the interior of the output pipe is provided on the output pipe, a cover plate is installed at one end of the valve body, and a rubber ring gasket for abutting against the cover plate is fixedly connected to the valve body, and a filter element is provided inside the valve body.

[0006] Preferably, the sealing element includes a sealing plug and a sealing cap. The sealing plug is fixedly connected to the sealing cap and is used to abut against the inner peripheral wall of the output pipe. A flange is fixedly connected to the outer peripheral wall of the output pipe, and the sealing cap is fixedly installed on the flange by a limiting component.

[0007] Preferably, the limiting component includes a limiting strip and a spring. The outer peripheral wall of the flange is provided with a through groove, and the side of the flange away from the sealing cover is provided with a groove for embedding the limiting strip. The groove is connected to the through groove, and the depth of the groove is less than the thickness of the flange. The spring is located in the through groove and its two ends are fixedly connected to the limiting strip and the sealing cover, respectively.

[0008] Preferably, the filter element includes a filter plate, and the valve body has a slot that communicates with its interior for the filter plate to pass through. The outer peripheral wall of the valve body is fixedly connected to a mounting frame corresponding to the slot, and the slot communicates with the interior of the mounting frame. The mounting frame is fixedly mounted with a mounting cover by bolts, and the filter plate is fixedly mounted on the cover by a mounting component.

[0009] Preferably, the mounting component includes a mounting rod, one end of which is fixedly connected to the mounting cover, and the outer peripheral wall of the other end of the mounting rod is machined with external threads. The outer peripheral wall of the filter plate is provided with a threaded hole for engaging with the external threads of the mounting rod.

[0010] Preferably, a threaded ring is fixedly connected to the cover plate, the threaded ring abuts against the rubber ring gasket and the two are coaxially arranged, and a threaded groove is opened at one end of the valve body for cooperating with the threaded ring.

[0011] In summary, this utility model has the following beneficial effects: This solution installs multiple output pipes on the outer peripheral wall of the valve body. When only one output pipe is needed, the interior of the other output pipes is sealed by a sealing element, allowing the user to install two pipes on the valve body and one of the unsealed output pipes respectively. When multiple output pipes need to be used simultaneously, the sealing element is removed to allow the interior of multiple output pipes to communicate with the outside. Then, multiple pipes can be installed on the valve body and multiple output pipes respectively, which can meet the simultaneous installation requirements of multiple outlets. Furthermore, a filter element is installed in the valve body so that impurities in the fluid can be filtered during the process of fluid flowing into the valve body through the pipe connected to the valve body.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Example:

[0019] A gas pressure reducing valve, such as Figures 1 to 4As shown, the valve includes a valve body 1, with a flange 2 welded to it. Multiple output pipes 2, connected to the interior of the valve body 1, are welded to the outer peripheral wall of the valve body 1. There are four output pipes 2. Sealing elements 3 are installed on the output pipes 2 to seal their interiors. The number and position of the sealing elements 3 correspond one-to-one with the number of output pipes 2. A cover plate 4 is installed at one end of the valve body 1, and a rubber ring gasket 5 is adhered to the valve body 1 to abut against the cover plate 4. A filter element is installed inside the valve body 1. The sealing elements 3 include a sealing plug 301 and a sealing cap 302. The sealing plug 301 is adhered to the sealing cap 302. The sealing plug 301 is made of rubber and is used to abut against the inner peripheral wall of the output pipes 2. A flange 7 is welded to the outer peripheral wall of the output pipes 2. The sealing cap 302... The limiting assembly is fixedly installed on flange 7. The limiting assembly includes a limiting strip 8 and a spring 9. A through groove 10 is opened on the outer peripheral wall of flange 7. The inner wall of the through groove 10 is not connected to the inner peripheral wall of flange 7. A groove 11 for embedding the limiting strip 8 is opened on the side of flange 7 away from the sealing cover 302. The groove 11 is connected to the through groove 10. The groove depth of the groove 11 is less than the thickness of flange 7. The spring 9 is located in the through groove 10 and its two ends are welded to the limiting strip 8 and the sealing cover 302 respectively. Two limiting assemblies are installed on the sealing cover 302. A threaded ring 16 is welded on the cover plate 4. The threaded ring 16 abuts against the rubber ring gasket 5 and the two are coaxially arranged. A threaded groove for cooperating with the threaded ring 16 is opened at one end of the valve body 1.

[0020] The filter element includes a filter plate 6 with multiple mesh holes. The valve body 1 has a slot 12 that communicates with its interior, through which the filter plate 6 passes. The outer peripheral wall of the valve body 1 is welded with a mounting frame 13 corresponding to the slot 12, which communicates with the interior of the mounting frame 13. The mounting frame 13 is fixedly mounted with a mounting cover 14 by bolts. Both the mounting frame 13 and the mounting cover 14 have screw holes for bolt connection. The filter plate 6 is fixedly mounted on the cover plate 4 by a mounting component, which includes a mounting rod 15. One end of the mounting rod 15 is welded to the mounting cover 14, and the outer peripheral wall of the other end of the mounting rod 15 is machined with external threads. The outer peripheral wall of the filter plate 6 has threaded holes for mating with the external threads of the mounting rod 15.

[0021] The user installs the cover plate 4 at one end of the valve body 1 until the threaded ring 16 is threaded into the threaded groove, and the threaded ring 16 abuts against the inner circumferential wall of the rubber ring gasket 5. The rubber ring gasket 5 increases the sealing between the cover plate 4 and the valve body 1. Bolts are installed in the screw holes on the mounting frame 13 and the mounting cover 14 respectively, so that the filter plate 6 is located inside the valve body 1 and the mounting rod 15 is located inside the mounting frame 13. When only one output pipe 2 is used, the other unused output pipe 2 is sealed inside by the sealing element 3. At this time, the sealing plug 301 is inserted into the output pipe 2, so that the sealing plug 301 abuts against the inner circumferential wall of the output pipe 2. Then, the spring 9 is pulled to stretch it and drive the limiting strip 8 to move away from the outer circumferential wall of the flange 7. The spring 9 is moved to position it in the through groove 10. Then, the spring 9 is released to allow it to elastically return until the limiting strip 8 is embedded in the groove 11. The sealing cover 302 can be easily installed on the flange 7, and the sealing plug 301 and the sealing cover 302 are aligned. The unused output pipe 2 has a sealing effect inside. The user can then install the two pipes on flange 2 of valve body 1 and flange 7 of one of the output pipes 2 respectively using mounting bolts. When multiple output pipes 2 are used at the same time, the user pulls the limiting strip 8 towards the valve body 1 and causes the spring 9 to stretch, so that the limiting strip 8 is disengaged from the groove 11. Then, the user moves the limiting strip 8 and the spring 9 away from flange 7 until the spring 9 is disengaged from the through groove 10. Then, the user pulls the sealing cover 302 by hand and causes the sealing plug 301 to move until the sealing plug 301 is completely disengaged from the inside of the output pipe 2, so that the sealing element 3 can be removed from the output pipe 2. This allows the inside of multiple output pipes 2 to be connected to the outside. Multiple pipes can then be installed on multiple output pipes 2 to meet the simultaneous installation requirements of multiple outlets. The user removes the cover plate 4 so that it is not installed on the valve body 1 until the threaded ring 16 is disengaged from the threaded groove and the threaded ring 16 is not in contact with the rubber ring gasket 5. Then, the inside of the valve body 1 can be cleaned.

[0022] When the pipes are installed on the valve body 1 and the output pipe 2 respectively, fluid is introduced into the pipe installed on the valve body 1 and flows into the valve body 1. The fluid will come into contact with the filter plate 6, and the filter plate 6 can filter the impurities in the fluid, thus achieving a filtration effect. When the filter plate 6 is attached with impurities and needs to be cleaned, first remove the bolts to make it disengage from the screw holes on the mounting frame 13 and the mounting cover 14 respectively. Then, hold the mounting cover 14 and move the mounting cover 14 away from the mounting frame 13. During the movement of the mounting cover 14, it will drive the mounting rod 15 and the filter plate 6 to move respectively. At this time, the filter plate 6 will first pass through the slot 12 and make the filter plate 6 disengage from the valve body 1. Then, continue to pull the mounting plate to drive the mounting rod 15 and the filter plate 6 to move until the mounting rod 15 and the filter plate 6 are both disengaged from the inside of the mounting frame 13 and can be removed to clean the filter plate 6. By rotating the filter plate 6, the external thread on the outer peripheral wall of one end of the mounting rod 15 will gradually disengage from the threaded hole on the filter plate 6, so that the filter plate 6 can be removed from the mounting rod 15 and replaced.
