Description

Technical Field

[0001] This utility model relates to the field of air pressure detection technology, specifically a pressure controller suitable for air pressure equipment. Background Technology

[0002] Pressure controllers are widely used in numerous industrial and civilian applications, and the unobstructed flow of their valve venting channels is crucial for the normal operation and safety of the system. However, in actual use, venting channels often become clogged due to the accumulation of impurities, moisture, oil, and other contaminants, leading to abnormal pressure regulation, equipment malfunctions, and even safety hazards. Existing technologies mostly focus on traditional methods such as periodic cleaning and pre-filtering, which are insufficient to fundamentally solve the problem of venting channel blockage. Conventional pressure controller valve venting channels have a simple structure, often being straight-through channels without protective mechanisms. When gas carrying impurities flows in, it easily deposits within the channel. Although some products add filters at the inlet end, the filters themselves are prone to clogging and cannot prevent small particles from entering the venting channel. In addition, some equipment uses periodic manual purging or chemical cleaning to unclog the venting holes, but this is cumbersome, costly, and cannot prevent blockages in real time. Once a blockage is not detected in time, it has already damaged the system equipment. Summary of the Invention

[0003] This invention provides a pressure controller suitable for pneumatic equipment to address the technical deficiencies of the prior art.

[0004] To solve the above-mentioned technical problems, the present invention provides a pressure controller suitable for pneumatic equipment, comprising an air source, an air inlet channel, an air inlet valve, an equipment pressure chamber, an air outlet valve, and an air outlet channel. The air source, air inlet channel, air inlet valve, equipment pressure chamber, air outlet valve, and air outlet channel constitute a complete sealed air circuit. A pressure sensor is provided inside the equipment pressure chamber. The device also includes a controller. The pressure sensor is connected to the controller for signal input, and the controller is connected to the air inlet valve and air outlet valve for signal output. The air outlet channel is a spirally converging air outlet channel that extends outward in a spiral shape with the air outlet valve as the center and the diameter gradually decreases.

[0005] Specifically, the helix angle of the spiral structure is 15° to 30°, and the channel length is set according to the impurity particle size and gas flow rate.

[0006] Specifically, the ratio of the inlet diameter to the outlet diameter of the tapered structure is 2:1 to 4:1.

[0007] Specifically, the inner wall of the spiral channel is coated with a smooth hydrophobic coating.

[0008] Specifically, a filter screen is provided between the air source and the air intake channel.

[0009] Specifically, a rubber sealing ring is provided at the connection between the air intake valve and the air intake channel, and at the connection between the air outlet valve and the air outlet channel.

[0010] Specifically, the spiral channel is made of special alloy steel that is corrosion-resistant and wear-resistant.

[0011] Specifically, the spiral channel outlet is equipped with an electrostatic eliminator.

[0012] Specifically, a collection box is provided at the lower part of the spiral channel outlet.

[0013] Because the exhaust channel is a spiral-shaped, tapering exhaust channel that extends outwards in a spiral shape with the valve as the center and the diameter gradually decreases, this structure causes the gas to form a swirling flow during the exhaust process. The centrifugal force of the spiral structure separates most of the impurities to the center of the channel and discharges them directly. A small number of impurities may adhere to the inner wall of the channel. Due to the tapering structure, the airflow is accelerated, and the high-speed airflow will have a scouring effect on the impurities attached to the inner wall of the channel, carrying away and discharging these attached impurities. This prevents impurities from being directly deposited in key parts, thus enabling the exhaust channel to have self-cleaning ability. This avoids the additional costs and subsequent unblocking of the vent holes by regularly manually blowing or chemically cleaning them, achieving low-cost real-time unblocking.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the described embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by a person of ordinary skill in the art to which this application pertains.

[0020] like Figure 1 , Figure 2 As shown, this utility model provides a pressure controller suitable for pneumatic equipment, including an air source 1, an air inlet channel, an air inlet valve 2, an equipment pressure chamber 3, an air outlet valve 5, and an air outlet channel 6. The air source 1, air inlet channel, air inlet valve 2, equipment pressure chamber 3, air outlet valve 5, and air outlet channel 6 form a complete sealed air circuit. A pressure sensor 4 is installed inside the equipment pressure chamber 3. The system also includes a controller 7. The pressure sensor 4 is connected to the controller 7 for signal input, and the controller 7 is connected to the air inlet valve 2 and air outlet valve 5 for signal output. The air outlet channel... Channel 6 is a spirally tapering venting channel that extends outward in a spiral shape, centered on the vent valve 5, with its diameter gradually decreasing. The controller 7 collects real-time pressure values ​​detected by the pressure sensor 4 inside the pressure chamber 3 and compares them with a pre-set pressure threshold. When the real-time pressure value is less than the threshold, the controller instructs the inlet valve 2 to open and the vent valve 5 to close. Conversely, when the real-time pressure value is greater than the threshold, the controller instructs the inlet valve 2 to close and the vent valve 5 to open, thereby maintaining the stability of the pressure inside the pressure chamber. This invention abandons the traditional straight-through vent hole and designs a spirally tapering venting channel. The channel extends outward in a spiral shape, centered on the vent valve 5, with its diameter gradually decreasing. The spiral structure creates a swirling flow of gas during discharge, using centrifugal force to separate most impurities to the center of the channel for direct discharge. A small portion of impurities may adhere to the inner wall of the channel. Due to the tapering structure, the airflow accelerates, and the high-speed airflow washes away these impurities, preventing them from depositing directly in critical areas. For example, if the initial diameter of the channel is X millimeters, the diameter decreases by a certain percentage (e.g., 5%) with each rotation along the spiral path (e.g., 90 degrees) until the outlet diameter is reduced to a suitable size (e.g., half the initial diameter), ensuring a moderate gas flow rate and significant impurity separation.

[0021] Specifically, the spiral angle of the spiral structure is 15° to 30° to balance centrifugal force and airflow resistance, and the channel length is set according to the impurity particle size and gas flow rate to ensure separation efficiency.

[0022] Specifically, the ratio of the inlet diameter to the outlet diameter of the tapered structure is 2:1 to 4:1, which can achieve a better separation effect.

[0023] Specifically, the inner wall of the spiral channel is coated with a smooth hydrophobic coating, which can reduce the accumulation of impurities, moisture, oil, etc., and also reduce airflow resistance.

[0024] Specifically, the air source 1 is equipped with a filter screen between the air intake channels to prevent impurities, moisture, oil, etc. from entering the air pressure equipment.

[0025] Specifically, rubber sealing rings are provided at the connection points between the intake valve 2 and the intake channel, and between the exhaust valve 5 and the exhaust channel 6, to prevent leakage of pressurized gas from the complete air path.

[0026] Specifically, the spiral channel is made of corrosion-resistant and wear-resistant special alloy steel, which can withstand the scouring of high-speed airflow and resist chemical corrosion, ensuring long-term stable operation.

[0027] Specifically, the spiral channel outlet is equipped with an electrostatic eliminator. In flammable and explosive environments, the vent may be equipped with an electrostatic eliminator to ensure the safety of the exhaust process.

[0028] Specifically, a collection box is provided at the lower part of the spiral channel outlet to avoid environmental pollution and facilitate regular manual cleaning.

[0029] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any variations or modifications to the above embodiments that are within the spirit and essence of the present invention will fall within the scope of the claims of the present invention.
