Intelligent identification valve for practical training and examination device

Abstract

The invention discloses an intelligent identification valve for a practical training and examination device, which comprises a valve, a bottom step of the valve and a right valve fixing ring, a rotating rod penetrates through the inner side of the valve fixing ring, a clamp is clamped on the side surface of the rotating rod, a fixing strip is welded at one end, far away from the rotating rod, of the clamp, and a connecting piece is fixedly connected under the clamp. An upper gasket is fixedly connected to the bottom of the connecting piece, a fixing screw penetrates through the top of the upper gasket, a lower gasket is fixedly connected to the bottom of the upper gasket through the fixing screw, a valve cavity is welded to the bottom of the lower gasket, pipeline connecting pipes penetrate through the two sides of the valve cavity, and a valve fixing plate is welded to the ends, away from the valve cavity, of the pipeline connecting pipes; an NFC chip is embedded in the front face of the valve cavity, the fixing plate gasket is connected to the side face of the valve fixing plate in a clamped mode, the NFC chip, the PDA hand operator and the motor are arranged, the current valve state can be rapidly obtained and changed through the design, and the valve opening and closing time is greatly saved in practical training and assessment.

Description

technical field [0001] The invention relates to the technical field of valve tools, in particular to an intelligent identification valve used for training and assessment devices. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve, etc. The valve can be used to control various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. flow. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, non-standard custom-made valves, etc. according to the material. [0003] However, most of the existing valves ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an intelligent identification valve used for training and assessment devices to solve the above-mentioned background technology that most of the valves need to be manually switched on and off, resulting in cumbersome operations, and the existing valves are in use. When the valve is prone to slipping, at the same time, the valve is prone to liquid leakage when it is connected to the pipeline, and it is inconvenient to disassemble when cleaning the inside of the valve.
