Slow-closing back pressure valve and slow-closing back pressure valve monitoring system

Abstract

The invention discloses a slow-closing back pressure valve and a slow-closing back pressure valve monitoring system. The slow-closing back pressure valve comprises a valve body. A water inlet cavity is formed in the valve body, a water inlet hole is formed in the end of the water inlet cavity, a downward pressing hole is formed in the side face of the water inlet hole, and a gasket is arranged on the inner side of the downward pressing hole; a water outlet cavity is formed in the side face of the downward pressing hole, a slow-closing cavity is formed in the top of the water outlet cavity, a valve rod is arranged in the slow-closing cavity, and a downward pressing plate is fixedly arranged on the valve rod; and a first pressure sensor is arranged on one side of the downward pressing plate and a limiting block is arranged on the other side of the downward pressing plate, and a first protective block is arranged on the first pressure sensor. According to the slow-closing back pressure valve and the slow-closing back pressure valve monitoring system, the first pressure sensor, a second pressure sensor and a server are arranged so as to conveniently detect whether a downward pressing spring can generate enough thrust to the downward pressing plate or not, if no, maintenance personnel are arranged as soon as possible to arrive at a site to conduct maintaining, so that the maintenance efficiency is greatly improved, the time is saved, and the influence on life of high-rise users is avoided.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a slow-closing check valve and a monitoring system for the slow-closing check valve. Background technique [0002] Slow-closing check valves are generally installed on the water supply pipelines of high-rise buildings. Slow-closing check valves are also called check valves. Their function is to prevent the backflow of water in the pipeline. Or close the valve to prevent water from flowing backward. When the water pump is turned on, water enters the middle cavity through the conduit, pushing the piston up, and the main valve opens. When the water pump stops working, the piston returns to the pressure drop, and the main valve also slowly closes. , but the existing slow-closing check valves still have some shortcomings in the use of water supply in high-rise buildings. For example, when the slow-closing check valves are damaged, the high-rise water supply system will fail due to envi...

[0002] Slow-closing check valves are generally installed on the water supply pipelines of high-rise buildings. Slow-closing check valves are also called check valves. Their function is to prevent the backflow of water in the pipeline. Or close the valve to prevent water from flowing backward. When the water pump is turned on, water enters the middle cavity through the conduit, pushing the piston up, and the main valve opens. When the water pump stops working, the piston returns to the pressure drop, and the main valve also slowly closes. , but the existing slow-closing check valves still have some shortcomings in the use of water supply in high-rise buildings. For example, when the slow-closing check valves are damaged, the high-rise water supply system will fail due to environmental problems, affecting the normal water supply work of high-rise buildings. , because the information transmission takes a certain amount of time, and usually the maintenance personnel will arrive at the scene for troubleshooting after a period of time, and the maintenance can only be started after the slow-closing check valve is confirmed to be faulty. The whole process will waste a lot of time, thus affecting people's Convenience makes a big difference
