Description

Technical Field

[0001] This utility model relates to the field of pneumatic regulating valve technology, specifically to a shock-resistant and stable pneumatic regulating valve. Background Technology

[0002] Pneumatic control valves use compressed gas as a power source and a cylinder as an actuator. They are driven by accessories such as valve positioners, converters, solenoid valves, position-holding valves, air tanks, and gas filters to achieve on / off or proportional regulation. They receive control signals from industrial automation control systems to regulate the media in pipelines.

[0003] However, existing anti-vibration and stabilizing pneumatic control valves have the following disadvantages: (1) The existing anti-vibration stable pneumatic regulating valve has a weak sealing function. When the existing device is subjected to external shaking or impact, gaps will be generated between the regulating valve and the pipes connected at both ends, which may cause leakage problems in the device.

[0004] (2) The existing anti-vibration stable pneumatic regulating valve has a weak anti-vibration function. After the existing device is installed, there is no effective anti-vibration structure. If the device shakes, the internal valve core may be affected and its operation may be affected. Utility Model Content
