Earthquake sensing detection valve device

Abstract

The invention relates to a vibration detection valve device, which is composed of a base, a docking device, an interface pipeline, a vibration measurement sensor, a permanent magnet and an electromagnetic adsorption device. The base is made of a hollow steel plate, filled with sand and soil. The steel plate has a certain quality, which acts as a fixing device and ensures that the detection device has a certain degree of freedom. The sand and soil can imitate the actual geological conditions. There is a support seat for the interface pipeline on the base, and a docking device is installed on the pipeline for connecting valves of different specifications. A vibration measurement sensor is installed below the valve installation position to detect the vibration resistance of the valve and read out the data. A vibration generating device is installed on one side of the base, and the devices are divided into two groups to generate horizontal and vertical vibrations respectively. Each group of two electromagnetic adsorption devices is placed opposite to each other, and a permanent magnet is fixed by a spring in the middle, and the two electromagnetic adsorption devices are alternately energized so that the permanent magnet vibrates to drive the whole device.

Description

technical field [0001] The invention relates to a shock detection valve device. Background technique [0002] The valve is a control component in the pipeline fluid conveying system, which is used to change the passage section and the flow direction of the medium, and has the functions of diversion, cut-off, throttling, check, diversion or overflow and pressure relief. Due to the wide range of uses of the valve, it also plays a great role in the pipeline. The nuclear valve is not only a system control and adjustment device, but also a pressure-bearing equipment. Its operation is related to the failure control and safe operation of the reactor, and its importance can be imagined. According to the statistics of nuclear safety accidents by the International Atomic Energy Organization, nuclear safety accidents caused by valve leakage account for a large proportion of all accidents, so the safety and reliability of nuclear valves must be paid attention to. Among them, the hazar...

Problems solved by technology

At present, there are very few anti-seismic detection devices for valves in my country, and they are all relatively complicated. The detection is time-consuming and labor-intensive, and the simulated vibration direction is not comprehensive, and the applicable valves are relatively single.
