Nuclear power plant conventional island valve fault monitoring device

Abstract

The invention relates to a nuclear power plant conventional island valve fault monitoring device which comprises a valve body, a valve cover and a valve element. An inlet and an outlet are formed in the two sides of the interior of the valve body respectively, a fixing circular ring is arranged on the inlet of the valve body, a filtering sieve plate and a monitoring assembly are arranged in the fixing circular ring, and the monitoring assembly comprises a box body, a distance sensor, a supporting rod, a single-chip microcomputer and an alarming device; a piston is arranged in the box body, the right side of the piston is provided with a distance measuring ball, the distance measuring ball corresponds to the distance sensor, the right end of the supporting rod transversely penetrates through the top of the box body and is connected with the left side of the piston, the right end of the supporting rod is connected with the edge of the filtering sieve plate, the two ends of an elastic piece are fixedly connected with the top of the box body and the filtering sieve plate respectively, and the distance sensor is connected with the single-chip microcomputer; and the single-chip microcomputer is connected with the alarming device. By means of the nuclear power plant conventional island valve fault monitoring device, the problems that an alarm cannot be given out in time when the interior of a valve of an existing nuclear power plant is blocked, workers cannot take corresponding measures in time, serious accidents occur, and the using requirements of the nuclear power plant cannot be met are effectively solved.

Description

technical field [0001] The invention relates to the technical field of valves in nuclear power plants, in particular to a fault monitoring device for conventional island valves in nuclear power plants. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of varieties and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. [0003] At present, when the existing nuclear power plant valves are in use, the inside of the valve is clogged, the valve fails to monitor and alarm the fluid in real ti...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a conventional island valve fault monitoring device for nuclear power plants in view of the deficiencies in the prior art. Through the coordinated design of the valve body, valve cover, valve core, fixed ring, filter sieve plate and monitoring components, the problem can be effectively solved. The blockage of the valve in the existing nuclear power plant failed to issue an alarm in time, and the staff could not take corresponding measures in time, resulting in serious accidents and failing to meet the needs of nuclear power plants.
