Description

Technical Field

[0001] This utility model relates to the field of gas pressure reduction technology, and more specifically, to a gas pressure reduction output device. Background Technology

[0002] A gas pressure reducing output device is a key piece of equipment for ensuring the safe and accurate use of gases. It is mainly used to reduce high-pressure gases from large-volume cylinders, medium-volume cylinders, or other gas source devices to a pressure suitable for various gas-using devices. It is widely used in industrial production, laboratory research, and some special gas usage scenarios, and is an indispensable device in the process of gas transportation and use, providing strong support for the rational utilization of gases and the safe operation of the system.

[0003] Existing gas pressure reducing output devices are typically equipped with multiple pressure gauges for pressure monitoring and safety assurance. However, when these devices are used in industrial environments, such as chemical production workshops, there are various volatile chemicals and dust in the surrounding environment. These substances may adhere to the surface of the pressure gauges, affecting the accuracy of the readings. In view of this, we propose a gas pressure reducing output device. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a gas pressure reducing output device. The technical problem to be solved by the present invention is that when the pressure gauge in the existing gas pressure reducing output device is used in an industrial environment, dust or chemicals will adhere to the surface of the pressure gauge, affecting the accuracy of the reading. In view of this, we propose a gas pressure reducing output device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A gas pressure reducing output device includes a left pressure reducing valve assembly and a right pressure reducing valve assembly. Both ends of the left and right pressure reducing valve assemblies are fixed and connected to high-pressure hoses. The left and right pressure reducing valve assemblies are connected via a three-way connector. Pressure gauges are fixed and connected to the outer sides of the left and right pressure reducing valve assemblies and the three-way connector. A base is fixedly installed on the outer side of each pressure gauge, and a protective shell is threaded onto each base. A support rod is jointly installed on the outer side of both the left and right pressure reducing valve assemblies via clamps. Multiple cleaning rods are rotatably connected to the bottom surface of the support rods. The multiple cleaning rods are connected by a synchronization mechanism, and the outer side of each cleaning rod contacts the outer side of the corresponding protective shell.

[0007] like Figure 1-3As shown, the specific implementation method is as follows: by setting up a left pressure reducing valve assembly and a right pressure reducing valve assembly, after the external gas is input, two pressures of output gas within the rated range can be obtained. Both the left and right pressure reducing valve assemblies are equipped with a set of safety valves, which play an automatic overload unloading protection role in the gas supply pipeline. The pressure gauge is protected by a protective shell to reduce the impact of chemical corrosion and dust on the reading accuracy. At the same time, the setting of clamps and support rods facilitates the quick disassembly of the cleaning rods. Simultaneously, the synchronous mechanism drives each cleaning rod to rotate, thereby cleaning the dust on the outside of the protective shell.

[0008] In a preferred embodiment, the synchronization mechanism includes multiple rotating shafts, each rotating shaft being rotatably connected to the bottom surface of a support rod, and each cleaning rod being fixedly installed on the outer side of a corresponding rotating shaft. Each rotating shaft is equipped with a sprocket, and multiple sprockets are fitted together with a chain, with each sprocket meshing with the chain.

[0009] In a preferred embodiment, a cleaning pad is fixedly installed on the outer side of each cleaning rod, and the outer side of each cleaning pad is in contact with the outer side of the corresponding protective shell.

[0010] In a preferred embodiment, a motor is fixedly mounted on the top surface of the support rod, and the output shaft of the motor passes through the support rod and is connected to a rotating shaft at a corresponding position.

[0011] In a preferred embodiment, pressure regulating handles are installed on the outer sides of both the left and right pressure reducing valve assemblies, and connecting nuts are installed at both ends of each high-pressure hose.

[0012] In a preferred embodiment, each of the cleaning rods is L-shaped, and each of the protective shells is made of polycarbonate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up a protective shell, sprocket, chain, cleaning rod, and other devices, achieves the purpose of protecting the pressure gauge with a protective shell to prevent dust or chemical substances from affecting the reading accuracy of the pressure gauge. At the same time, by starting the motor, each shaft is driven to rotate synchronously with the cooperation of the sprocket and chain, thereby driving each cleaning rod to rotate synchronously, and cleaning the protective shell with the cleaning pad.

[0015] 2. By setting up devices such as a left pressure reducing valve and a right pressure reducing valve, this utility model enables the output gas to be obtained at two pressures within the rated range after the external gas is input, thereby meeting the purpose of diverse gas demand.

[0016] In summary, this utility model is simple to operate, can protect the pressure gauge through the protective shell, and can simultaneously clean multiple protective shells to avoid dust or chemicals affecting the reading accuracy of the pressure gauge. It can also provide two pressure output gases within the rated range to meet diverse gas usage needs. Attached Figure Description

[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] Reference Figure 1-3 A gas pressure reducing output device includes a left pressure reducing valve assembly 1 and a right pressure reducing valve assembly 2. Both ends of the left pressure reducing valve assembly 1 and the right pressure reducing valve assembly 2 are fixed and connected to a high-pressure hose 4. The left pressure reducing valve assembly 1 and the right pressure reducing valve assembly 2 are connected through a three-way seat 3. Pressure gauges 8 are fixed and connected to the outside of the left pressure reducing valve assembly 1, the right pressure reducing valve assembly 2 and the three-way seat 3. A base 9 is fixedly installed on the outside of each pressure gauge 8. A protective shell 11 is threadedly connected to each base 9. A support rod 5 is jointly installed on the outside of the left pressure reducing valve assembly 1 and the right pressure reducing valve assembly 2 through a clamp 6. Multiple cleaning rods 12 are rotatably connected to the bottom surface of the support rod 5. The multiple cleaning rods 12 are connected by a synchronization mechanism, and the outside of each cleaning rod 12 is in contact with the outside of the corresponding protective shell 11.

[0023] like Figure 1-3As shown, the specific implementation method is as follows: by setting the left pressure reducing valve assembly 1 and the right pressure reducing valve assembly 2, after the external gas is input, two pressures of output gas within the rated range can be obtained. Both the left pressure reducing valve assembly 1 and the right pressure reducing valve assembly 2 are equipped with a set of safety valves, which play an automatic overload unloading protection role in the gas supply pipeline. The pressure gauge 8 is protected by the protective shell 11 to reduce the impact of chemical corrosion and dust on the reading accuracy. At the same time, the setting of the clamp 6 and the support rod 5 facilitates the quick disassembly of the cleaning rod 12. Meanwhile, the synchronous mechanism drives each cleaning rod 12 to rotate, thereby cleaning the dust on the outside of the protective shell 11.

[0024] The synchronization mechanism includes multiple rotating shafts 10, each of which is rotatably connected to the bottom surface of the support rod 5. Each cleaning rod 12 is fixedly installed on the outside of the corresponding rotating shaft 10. Each rotating shaft 10 is equipped with a sprocket 15. Multiple sprockets 15 are fitted together with a chain 16, and each sprocket 15 meshes with the chain 16. It is worth noting that since each sprocket 15 meshes with the chain 16, when the chain 16 rotates, each sprocket 15 can be adjusted to rotate synchronously.

[0025] Each cleaning rod 12 is fixedly installed with a cleaning pad 13 on its outer side, and the outer side of each cleaning pad 13 is in contact with the outer side of the corresponding protective shell 11. The cleaning pad 13 can be made of rubber to avoid damage to the protective shell 11.

[0026] A motor 14 is fixedly installed on the top surface of the support rod 5, and the output shaft of the motor 14 passes through the support rod 5 and is connected to the corresponding rotating shaft 10, providing a power source for the rotation of the cleaning rod 12.

[0027] Both the left pressure reducing valve assembly 1 and the right pressure reducing valve assembly 2 are equipped with pressure adjusting handles 7 on their outer sides. Each high-pressure hose 4 is equipped with a connecting nut at both ends, which facilitates quick installation and disassembly of the high-pressure hose 4.

[0028] Each cleaning rod 12 is L-shaped, and each protective shell 11 is made of polycarbonate, a thermoplastic engineering plastic with good transparency and corrosion resistance.

[0029] When using this utility model, first connect the two high-pressure hoses 4 to the gas-using device and the gas source device respectively through connecting nuts. Then, open the main valve of the gas source device and check the gas source pressure. Next, slowly rotate each pressure regulating handle 7 to make the left pressure reducing valve assembly 1 and the right pressure reducing valve assembly 2 open and close immediately, so that the high-pressure gas can clean the impurities in the pipeline. Then check the gas-using device to ensure that the control valve is in normal working condition. Then, adjust the left pressure reducing valve assembly 1 and the right pressure reducing valve assembly 2 by rotating the pressure regulating handle 7 and observe the corresponding pressure gauge 8. Adjust the gas source output pressure to the actual required pressure value. By setting the left pressure reducing valve assembly 1 and the right pressure reducing valve assembly 2, two pressure output gases within the rated range can be obtained, which is highly flexible.

[0030] Meanwhile, each pressure gauge 8 is protected by the protective shell 11 to reduce the impact of dust and chemicals on the reading accuracy. At the same time, the motor 14 is started, which drives one of the rotating shafts 10 to rotate. With the cooperation of the sprocket 15 and the chain 16, each rotating shaft 10 rotates synchronously, thereby driving each cleaning rod 12 to rotate synchronously, and cleaning the protective shell 11 through the cleaning pad 13.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
