Description

Technical Field

[0001] This utility model relates to the field of pneumatic single-seat regulating valve technology, specifically a pneumatic single-seat regulating valve. Background Technology

[0002] Pneumatic single-seat control valves are core terminal actuators in industrial automation control systems. Powered by compressed air, they receive pneumatic signals from the controller and drive the valve core to move linearly within the valve body, thereby changing the flow cross-sectional area between the valve core and the valve seat. This enables precise regulation and control of process parameters such as flow rate, pressure, temperature, and liquid level of the medium in the pipeline.

[0003] A pneumatic diaphragm regulating valve with publication number CN213745386U is easy to install. By placing the conveying component in the placement groove, aligning the first connecting block with the fixed block, and then locking the locking block in the slot, the conveying pipe can be fixed at one end of the first connecting pipe and the second connecting pipe, which is convenient for installation and fixation. At the same time, when disassembly is required, the regulating valve body can be quickly removed, which greatly saves the time of the workers.

[0004] This easy-to-install pneumatic diaphragm regulating valve allows for easy installation and fixation by placing the conveying assembly in the placement slot, aligning the first connecting block with the fixing block, and then locking the locking block in the slot. However, the pneumatic diaphragm regulating valve is relatively heavy, and the device lacks an adjustment support structure for it, making installation difficult for operators. Therefore, improvements are needed. Utility Model Content
