Laser control pneumatic ball valve opening and positioning device

Abstract

The invention discloses a laser control pneumatic ball valve opening locating device. The laser control pneumatic ball valve opening locating device comprises a valve body, a valve spool and a valve rod, wherein the top portion of the valve rod is provided with a valve rotary disc, the valve rotary disc is provided with a locating electromagnet and an energizing brake, a fixed disc and a valve rod rotary disc are arranged between the valve rod and the valve body, a photoelectric control chamber is arranged between the valve rod rotary disc and the valve body, a photosensitive element, a relay normally-open contact and an infrared laser transmitter are arranged in the photoelectric control chamber, a control air cylinder is further provided, the outer side of the valve body is further provided with a control chamber in signal connection with the photoelectric control chamber, and a manual controller, a relay coil matched with the relay normally-open contact and an inflating and deflating control circuit used for inflating from the two ends of the control air cylinder. The laser control pneumatic ball valve opening locating device has the advantages that the structure is simple, the control stability is good, the impact and vibration of the valve rod can be effectively avoided, the control accuracy is high, the control stability and reliability are strong, the accurate locking and locating of the valve opening angle is realized, the applicability is good and the practicability is strong.

Description

technical field [0001] The invention belongs to the technical field of valve body control devices, and in particular relates to a laser-controlled pneumatic ball valve opening and positioning device. Background technique [0002] With the gradual maturity of ball valve and butterfly valve technology, most of the ball valves and butterfly valves in the prior art are manually controlled, and the control accuracy and reliability are low, and the valve running speed of the existing technology is relatively unstable during operation. , The impact and vibration of the valve stem are relatively large, so the stability and service life of the valve body and valve stem will also be affected to a certain extent, and the applicability and practicability will be affected. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a laser-controlled pneumatic ball valve opening and positioning device with simple structure, good sta...
