A valve position monitoring and identification device for manual gate valve

Abstract

The invention relates to the field of gate valve mechanical control, and discloses a manual gate valve valve position monitoring and identifying device. The device comprises a valve position identifying device used for identifying the valve position and a monitoring software for monitoring the manual gate valve state information; the valve position identifying device comprises a main body part, alocking buckle and a key, the main body part is fixed on a gate valve hand wheel, and the locking buckle is fixed on a gate valve valve rod through a bolt; and an RFID belt is distributed in a the groove of the locking buckle and cooperates with an RFID belt on a lock rod for use, and the key is provided with an RFID signal reading device for reading and storing the current switch state of the valve position identifying device. According to the manual gate valve valve position monitoring and identifying device, implementation is convenient, the manufacturing cost is low, wiring of communication signals does not need to be considered, electronic supervision of the manual gate valve is realized, and the problem of "blind operation" of the manual gate valve is solved.

Description

technical field [0001] The invention relates to the field of mechanical control of gate valves, in particular to a valve position monitoring and identification device for manual gate valves. Background technique [0002] The gate valve (gate valve) is an opening and closing member gate, and the direction of movement of the gate is perpendicular to the direction of the fluid. The gate valve of the gate valve moves in a straight line with the valve stem, which is called a lifting stem gate valve, also called a rising stem gate valve. Usually there is a trapezoidal thread on the lifter, and through the nut at the top of the valve and the guide groove on the valve body, the rotating motion is changed into a straight line motion, that is to say, the operating torque is changed into the operation thrust. In actual use, the apex of the valve stem is used as a sign, that is, the position where the valve stem does not move is taken as its fully open position. In order to consider t...

Problems solved by technology

However, wireless devices need to lay out wireless networks, and wired devices need to lay signal lines. These two modes are not good solutions for in-service chemical plants.

In addition, the power supply problem of the valve status monitoring device also needs to be solved: the wiring of the wired power supply method is cumbersome, and the battery method is not durable
