Description

Technical Field

[0001] The utility model relates to the technical field of brackets, in particular to a pneumatic valve limit switch bracket. Background Art

[0002] A valve is a device used to control the flow of fluids (liquids, gases, powders, etc.), usually used in pipeline systems. The horseshoe-shaped magnetic limit switch plays an important role in the valve control system. It is mainly used to detect the switch state and position of the valve in order to monitor and control the valve.

[0003] At present, the horseshoe-shaped magnetic induction limit switch is often composed of a magnetic stripe combination cap installed on the surface of the pneumatic actuator rotor and a magnetic sensor fixed on the surface of the valve. When the pneumatic actuator rotor rotates, it will drive the magnetic stripe combination cap to rotate, thereby transmitting magnetic field information to the magnetic sensor, thereby realizing the transmission of valve opening and closing information. Therefore, the current horseshoe-shaped magnetic induction limit switch is often close to the valve. When a high-temperature gas is passed into the pipeline, the magnetic stripe combination cap and the magnetic sensor may be continuously heated by the high temperature, thereby affecting normal use. Therefore, a new type of pneumatic valve limit switch bracket is needed to solve the above problems. Utility Model Content
