Description

Technical Field

[0001] The utility model relates to the field of fluid control, in particular to an adjustable gas decompression device. Background Art

[0002] A gas pressure reducer is a device used to reduce the pressure of a gas, usually to regulate the pressure of the gas as it flows through a pipe or pipeline. A gas pressure reducer can reduce the pressure from a high-pressure gas source to a pressure level more suitable for a specific application or equipment.

[0003] However, conventional gas pressure reducing devices usually use regulating valves for pressure regulation, which results in a slow response speed and is unable to quickly adapt to rapid changes in the working environment. The regulating valve requires additional energy support for adjustment, which increases energy consumption. Moreover, the regulating valve is a mechanical device and there is a possible risk of leakage, which affects the system pressure stability.

[0004] Therefore, the utility model provides an adjustable gas pressure reducing device to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an adjustable gas pressure reducing device. The utility model can accurately adjust the pressure of the gas pressure reducing device by adjusting the cross-sectional area of ​​the inner end of the valve body to ensure that the gas output pressure is stable and accurate.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an adjustable gas decompression device, comprising a valve body, an air inlet pipe is fixedly arranged on one side of the valve body, an air outlet pipe is fixedly arranged on the other side of the valve body, a connecting pipe is fixedly arranged on the outer ends of the air inlet pipe and the air outlet pipe, a pressure valve is fixedly arranged on the opposite ends of the two connecting pipes, a mounting groove is opened at the upper end of the valve body, an internal threaded cylinder is fixedly arranged on the inner end of the mounting groove, a threaded column is threadedly arranged on the inner end of the internal threaded cylinder, a bearing is fixedly sleeved on the lower end of the threaded column, a conical block is fixedly arranged on the lower end of the bearing, a partition is fixedly arranged on the inner end of the internal threaded cylinder close to the lower end, a spring is arranged on the other side of the air inlet pipe, a conical force-bearing block is fixedly arranged on the front end of the spring, a spiral water absorption layer is fixedly arranged on the inner end of the air inlet pipe, an air purification layer is fixedly arranged on the inner end of the air outlet pipe, and an open-hole rubber ring is fixedly arranged on the other side of the upper end of the valve body;

[0007] Through the above technical solution, after the gas enters the air intake pipe, it first passes through the spiral water absorption layer to absorb moisture in the air, and then the gas enters the inner end of the valve body. When adjusting the gas pressure, it is only necessary to screw the threaded column downward to move the conical block downward, and the conical block squeezes the conical force block, causing it to move toward the spring direction. In this way, the conical force block withdraws from the inner end of the perforated rubber ring. Since there are multiple holes on the outer end of the perforated rubber ring, the speed of the gas passing through the valve body is increased, and then the gas is purified through the air purification layer.

[0008] Furthermore, sealing rings are fixedly provided at the connection between the air inlet pipe and the air outlet pipe and the valve body;

[0009] Through the above technical solution, the sealing ring is fixedly arranged at the connection between the inlet pipe, the outlet pipe and the valve body to effectively prevent gas leakage, ensure the normal operation of the valve system, and improve the sealing and stability of the system.

[0010] Furthermore, the spiral water absorption layer and the air purification layer are both arranged on opposite sides of the two connecting pipes;

[0011] Through the above technical solution, the setting of the spiral water absorption layer can ensure that the moisture can be effectively absorbed before the gas enters the valve body, preventing moisture from entering the gas system, helping to protect the equipment and components in the gas system, extending their service life, and reducing the damage caused by moisture to the system. The setting of the air purification layer can ensure that the impurities and pollutants in the gas are removed after passing through the purification layer, improving the purity and cleanliness of the gas, which is conducive to protecting downstream equipment and ensuring the normal operation of the system.

[0012] Furthermore, the spring is arranged at the inner end of the valve body, and the conical block is movably arranged at the upper end of the conical force-bearing block;

[0013] Through the above technical solution, the gas flow and pressure can be flexibly adjusted through the elastic action of the spring to meet the adjustment requirements of different needs. The provision of the spring can simplify the structure of the adjustment device, improve the operability of the adjustment device, and make the adjustment more convenient and effective.

[0014] Furthermore, a fixing ring is fixedly sleeved on the outer end of the internal threaded tube, and the two pressure valves are fixedly arranged on the upper end of the fixing ring;

[0015] Through the above technical solution, the setting of the fixing ring can ensure that the pressure valve is fixed in a suitable position, and keep the relative positions of the components inside the system stable.

[0016] Furthermore, the conical force-bearing block is movably arranged at the inner end of the perforated rubber ring, and the threaded column is threadedly arranged at the inner end of the partition;

[0017] Through the above technical solution, by movably setting the conical force-bearing block at the inner end of the perforated rubber ring and threadedly setting the threaded column at the inner end of the partition, the gas pressure can be accurately adjusted. The movement of the conical block can be controlled by twisting the threaded column, thereby adjusting the gas pressure, making the adjustment process more accurate and convenient.

[0018] Furthermore, the conical block is movably arranged at the lower end of the partition;

[0019] Through the above technical solution, by placing the conical block at the lower end of the partition, the structure of the regulating device can be made simpler and more compact, thereby improving the overall performance and operating efficiency of the system.

[0020] The utility model has the following beneficial effects:

[0021] 1. The utility model proposes an adjustable gas pressure reducing device.

[0035] By firstly absorbing moisture through the spiral water absorption layer 11, then adjusting the gas pressure, and finally purifying the gas through the air purification layer 15, the influence of factors such as rust, pollution or excessive pressure on the equipment and components can be effectively reduced, thereby extending the service life of the equipment and reducing maintenance costs. By firstly absorbing moisture in the air through the spiral water absorption layer 11, and then purifying the gas through the air purification layer 15, the quality of the gas can be effectively improved, the purity of the gas can be ensured, and malfunctions or damage caused by moisture or impurities can be avoided.

[0036] Working principle: After the gas enters the air intake pipe 1, it first passes through the spiral water absorption layer 11 to absorb moisture in the air, and then the gas enters the inner end of the valve body 3. When adjusting the gas pressure, just screw down the threaded column 8 to move the conical block 9 downward, and the conical block 9 squeezes the conical force block 13, causing it to move toward the spring 12.
