[0001] This utility model relates to the field of natural gas technology, and in particular to an unattended natural gas pressure regulating device for natural gas stations. Background Technology
[0002] With the rapid development of the natural gas industry, the performance and reliability of natural gas pressure regulating devices are of paramount importance as key equipment to ensure the safe and stable supply of natural gas. Against the backdrop of intelligent development in the energy sector, natural gas stations are gradually transforming towards unmanned operation and automated control.
[0003] In existing technologies, the connection between pressure regulating valves and inlet and outlet pipes is mostly fixed by flange bolts or welding. This connection structure requires the use of tools such as wrenches and welding machines during installation, which not only increases the complexity and time cost of on-site construction, but also makes it difficult to achieve automated and rapid disassembly and assembly in unattended scenarios. Utility Model Content
[0004] In existing technologies, the connection between the pressure regulating valve and the inlet and outlet pipes is mostly fixed by flange bolts or welding. This connection structure requires the use of tools such as wrenches and welding machines during installation, which not only increases the complexity and time cost of on-site construction, but also makes it difficult to achieve automated and rapid disassembly and assembly in unattended scenarios. This utility model provides an unattended natural gas pressure regulating device for natural gas stations.
[0005] The technical solution adopted by this utility model is: an unattended natural gas pressure regulating device for natural gas stations, including a pressure regulating valve, an inlet pipe, and an outlet pipe. The inlet pipe and the outlet pipe are respectively arranged on both sides of the pressure regulating valve. A connecting frame is sleeved on both sides of the pressure regulating valve. The connecting frame is equipped with a disassembly and assembly component that facilitates quick disassembly and assembly of the inlet pipe or the outlet pipe. The disassembly and assembly component includes a connecting ring fixedly installed on the surface of the inlet pipe and the outlet pipe. The connecting frame is also equipped with a fixing component that facilitates fixing the connecting frame to the pressure regulating valve. Through the combined design of the pressure regulating valve, the inlet pipe, the outlet pipe, and the connecting frame, the modularity of the natural gas pressure regulating device is realized, which facilitates installation, maintenance, and replacement. With the setting of the disassembly and assembly component and the fixing component, the installation and disassembly of the pressure regulating valve and the inlet pipe and the outlet pipe can be completed quickly, shortening the on-site construction time.
[0006] Furthermore, two symmetrical mounting rods are fixedly installed on one side of the connecting ring. A mounting groove is formed on one side surface of the connecting frame to mate with the two mounting rods. A snap-fit rod is positioned above the mounting groove, penetrating the upper surface of the connecting frame and slidingly connected to it. A first slot is formed on the upper surface of the mounting rod to mate with the snap-fit rod. Through the cooperation between the mounting rod on the connecting ring and the mounting groove on the connecting frame, and the snap-fit rod engaging with the first slot, quick assembly and disassembly of the air inlet and outlet pipes are achieved, facilitating pipe maintenance and replacement.
[0007] Furthermore, a sliding plate is fixedly installed on one side of the locking rod, and the sliding plate is slidably connected inside the connecting frame. A first spring is fixedly installed on the upper surface of the sliding plate, and the other end of the first spring is fixedly connected to the connecting frame. The locking rod is connected to the first spring through the sliding plate, so that the locking rod has an automatic reset and locking function, improving installation stability.
[0008] Furthermore, a connecting plate is fixedly installed on the top of the two locking rods on the same side, and the tops of the locking rods on the same side are fixedly connected through the connecting plate, which can realize the synchronous operation of the two locking rods.
[0009] Furthermore, the fixing assembly includes fixing rods fixedly installed on both sides of the upper surface of the pressure regulating valve. Each of the other surfaces of the two connecting frames has a fixing groove that matches the fixing rod. Sliding grooves are formed on both sides of the inner wall of each fixing groove. A locking block is slidably connected inside each of the sliding grooves on both sides. Second locking grooves that match the locking blocks are formed on both sides of the fixing rod. Two symmetrical second springs are fixedly installed inside each sliding groove. Both second springs are fixedly connected to one side of the locking block. Through the cooperation of the fixing rods and fixing grooves, and the locking of the locking blocks and second locking grooves, a stable connection between the connecting frame and the pressure regulating valve is achieved, ensuring the safe operation of the device.
[0010] Furthermore, both sides of the snap-fit block are beveled, and the side closer to the slide groove is wider. The beveled design of the snap-fit block makes it easier for the fixing rod to squeeze the snap-fit block during installation, allowing it to smoothly enter the fixing groove, thus improving the convenience of installation.
[0011] Furthermore, sealing rings are fixedly installed on the inner surfaces of both connecting frames. The design of the sealing rings effectively prevents natural gas leakage and improves the safety and reliability of the device.
[0012] The beneficial effects of this utility model are:
[0013] This invention, through the design of disassembly and fixing components, enables the rapid installation and disassembly of the pressure regulating valve with the inlet and outlet pipes, shortening on-site construction time. It solves the problem that in the prior art, the connection between the pressure regulating valve and the inlet and outlet pipes is mostly fixed by flange bolts or welding. This connection structure requires the use of tools such as wrenches and welding machines during installation, which not only increases the complexity and time cost of on-site construction, but also makes it difficult to achieve automated and rapid disassembly and assembly in unattended scenarios.

The connecting frame 4 is also equipped with a fixing component 6 to facilitate fixing the connecting frame 4 to the pressure regulating valve 1. Through the combined design of the pressure regulating valve 1, the inlet pipe 2, the outlet pipe 3, and the connecting frame 4, the modularity of the natural gas pressure regulating device is realized, which facilitates installation, maintenance, and replacement. With the setting of the disassembly and assembly component 5 and the fixing component 6, the installation and disassembly of the pressure regulating valve 1 with the inlet pipe 2 and the outlet pipe 3 can be completed quickly, shortening the on-site construction time.
[0024] Reference Figures 1 to 3 As shown, two symmetrical mounting rods 502 are fixedly installed on one side of the connecting ring 501. A mounting groove 503 that matches the two mounting rods 502 is opened on one side surface of the connecting frame 4. A locking rod 504 is provided above the mounting groove 503, passing through the upper surface of the connecting frame 4 and slidingly connected to it. A first locking groove 505 that matches the locking rod 504 is opened on the upper surface of the mounting rod 502. A sliding plate 506 is fixedly installed on one side of the locking rod 504, and the sliding plate 506 is slidably connected inside the connecting frame 4. A first spring 507 is fixedly installed on the upper surface of the sliding plate 506. The other end of the spring 507 is fixedly connected to the connecting frame 4. The top of the two snap-fit rods 504 on the same side is fixedly installed with a connecting plate 508. Pulling the connecting plate 508 upward will cause the snap-fit rods 504 on both sides to move upward at the same time. At the same time, the sliding plate 506 moves up and down, compressing the first spring 507. Align the connecting rings 501 on the air inlet pipe 2 and the air outlet pipe 3 with the mounting grooves 503 of the connecting frame 4. Insert the mounting rod 502 into the mounting groove 503. Release the connecting plate 508. The snap-fit rods 504 on both sides will move downward into the first slot 505 of the mounting rod 502 by the elastic force of the first spring 507, thus completing the firm fixation.
[0025] Reference Figure 1 , Figure 2 and Figure 4As shown, the fixing assembly 6 includes fixing rods 601 fixedly installed on both sides of the upper surface of the pressure regulating valve 1. Fixing grooves 602 that fit with the fixing rods 601 are provided on the other side surface of both connecting frames 4. Sliding grooves 603 are provided on both sides of the inner wall of the fixing grooves 602. Locking blocks 604 are slidably connected inside the sliding grooves 603 on both sides. Second locking grooves 605 that fit with the locking blocks 604 are provided on both sides of the fixing rods 601. Two symmetrical second springs 606 are fixedly installed inside the sliding grooves 603. Both second springs 606 are fixedly connected to one side of the locking block 604. The locking blocks 604 have two... All surfaces are beveled, with the side closer to the slide groove 603 being wider. Sealing rings 7 are fixedly installed on the inner surfaces of both connecting frames 4. Align the fixing groove 602 of the connecting frame 4 with the fixing rod 601 on the pressure regulating valve 1, and push the connecting frame 4 so that the fixing rod 601 enters the fixing groove 602. During this process, the fixing rod 601 will squeeze the snap-fit block 604, causing it to move to both sides of the slide groove 603 and compress the second spring 606. When the fixing rod 601 is fully inserted into the fixing groove 602, the snap-fit block 604 pops out under the action of the second spring 606 and snaps into the second snap-fit groove 605 on the fixing rod 601, achieving a firm fixation.
[0026] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:
[0027] In use, first attach the connecting frames 4 to both sides of the pressure regulating valve 1, align the fixing groove 602 of the connecting frame 4 with the fixing rod 601 on the pressure regulating valve 1, and push the connecting frame 4 so that the fixing rod 601 enters the fixing groove 602. During this process, the fixing rod 601 will squeeze the locking block 604, causing it to move to both sides of the slide groove 603 and compress the second spring 606. When the fixing rod 601 is fully inserted into the fixing groove 602, the locking block 604 pops out under the action of the second spring 606 and locks into the second locking groove 605 on the fixing rod 601, achieving a firm fixation. Disassembly is as simple as pulling the connecting frame 4 outward. Then, pull the connecting plate 508 upward, causing the locking rods 504 on both sides to move upward simultaneously. When the locking rods 504 move upward, the sliding plate 506 moves upward accordingly, compressing the first spring 507. Then, align the air inlet pipe 2 and the air outlet pipe 3 with the connecting frames 4 on both sides respectively, align the connecting ring 501 on the air inlet pipe 2 or the air outlet pipe 3 with the mounting groove 503 of the connecting frame 4, insert the mounting rod 502 into the mounting groove 503, release the connecting plate 508, and the locking rod 504 moves downward under the elastic force of the first spring 507, locking into the first locking groove 505 of the mounting rod 502, thus completing the fixation.
