Abstract
Description
Technical Field

[0002] The main function of an oxygen regulating valve is to control the oxygen content in compressed air or the oxygen flow and pressure in oxygen pipelines within a certain range to meet production requirements. It has integrated functions of measurement, execution, and control, automatically adjusting the pressure before the valve to achieve pressure stabilization and reduction. Oxygen regulating valves can be divided into several types, including manual, pneumatic, and electric. Manual regulating valves are operated directly by handwheels or handles, featuring a simple and reliable structure and convenient maintenance. However, they are significantly affected by human factors, and their sealing performance may be affected by the squeezing action during manual opening and closing. Pneumatic regulating valves use compressed air as a power source to drive the valve's action and consist of cylinders and electromagnets, among other accessories. Electric regulating valves control the opening and closing of the valve through an electric device. Different types of regulating valves are required depending on the specific application needs.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-2This utility model provides the following technical solution: an oxygen regulating valve, comprising a main body 1, a handle mounting hole 2, a manifold 3, a spring 4, a piston plate 5, a regulator 6, a retaining ring 8, a knob 9, a check valve 11, a filter element 12, a stud 13, a T-shaped handle 14, and a check valve mounting hole 19. The top of the main body 1 has the handle mounting hole 2. The manifold 3 is located inside the main body 1. A spring 4 is sleeved on the outer side of one end of the manifold 3. A piston plate 5 is sleeved inside the spring 4. The regulator 6 is located inside the main body 1, with one side of the regulator 6 abutting against one side of the piston plate 5. The bottom inner side of the main body 1 is movable. A knob 9 is mounted on the main body 1, and a retaining ring 8 is provided on one side of the knob 9. A check valve mounting hole 19 is provided inside the main body 1, and a check valve 11 is installed in the internal thread of the check valve mounting hole 19. A filter element 12 is provided inside the main body 1, and a stud 13 is installed in the internal thread of the main body 1. A T-shaped handle 14 is installed in the internal thread of one end of the main body 1. A regulator connecting block 20 is fixedly mounted on one end of the regulator 6. A flow guide 7 is movably mounted on the outside of the regulator 6 and the regulator connecting block 20, and the outside of the flow guide 7 is movably connected to the inside of the retaining ring 8. A connector 10 is installed in the internal thread of the main body 1.
[0019] In this embodiment, the flow divider 16, through its specific structure and layout, can divide the fluid into multiple channels or directions, ensuring uniform fluid distribution within the valve. This reduces the direct impact of the fluid on the valve, improves the valve's stability and service life, and the flow divider 16 can also reduce fluid pressure loss to a certain extent, improving the overall efficiency of the system.
[0020] In this embodiment, the flow guide 7 can guide the flow direction of oxygen inside the valve body, ensuring that oxygen can pass through the regulating valve smoothly and efficiently. The flow guide 7 can reduce the turbulence and eddies of the airflow inside the valve body, thereby reducing pressure drop loss and improving the stability of oxygen flow.
[0021] In this embodiment, the manifold 3 can distribute the input oxygen into different paths or channels to meet the oxygen requirements of a specific system or device. The manifold 3 ensures that oxygen can be delivered to each point of use according to a predetermined ratio and flow rate. The manifold 3 can optimize the oxygen flow path and reduce unnecessary pressure loss, which helps to reduce the system's energy consumption and improve overall efficiency.
[0022] Working principle and usage process of this utility model:
[0023] Option 1: After installation, the knob 9, in conjunction with the retaining spring 8, moves the flow guide 7. The flow guide 7 guides the flow direction of oxygen within the valve body, ensuring smooth and efficient passage of oxygen through the regulating valve. The retaining spring 8, through its elastic properties, regulates and controls the output pressure of the oxygen. When oxygen is input into the pressure reducing valve, the retaining spring is compressed to regulate the output pressure. When the output pressure exceeds the set value, the pressure relief mechanism inside the pressure reducing valve will start to function, releasing some oxygen to keep the output pressure within the set range. Through the movement of the retaining ring 8, it can work with the spring 4 and piston plate 5 to adjust the regulator 6, and can also work with the manifold 3 to distribute oxygen from the oxygen source to different channels or branches to meet the oxygen needs of different equipment or systems, thereby ensuring accurate oxygen distribution to meet the needs of various application scenarios. The check valve 11 can be connected to external equipment and can ensure unidirectional oxygen flow, preventing oxygen backflow or leakage, thereby ensuring stable operation of the device. The filter element 12 can filter the passing gas, thereby ensuring the quality of oxygen supply and protecting the precision components inside the oxygen regulating valve from the corrosion and wear of impurities. The position of the throttling element inside the valve can be changed by adjusting the T-shaped handle 14, thereby adjusting the oxygen flow and pressure through the valve. The connector 10 can improve the applicability of the device, thereby meeting various usage needs. All electrical equipment in this device is powered by an external power source.
[0024] Option 2: The knob 9, in conjunction with the retaining ring 8, moves the flow divider 16. The flow divider 16 can divide the fluid into multiple channels or directions, ensuring that the fluid is evenly distributed within the valve. The sleeve 15 improves the sealing of the device and provides protection to the device, preventing damage from unexpected situations, thereby improving the stability of the device. The instrument base 17 and instrument cover 18 reflect the oxygen flow rate and pressure, thus providing timely feedback on the oxygen supply status. All electrical equipment in this device is powered by an external power source.
