Pressure water tank for water conservancy project drainage station

Abstract

The invention discloses a pressure water tank for a water conservancy project drainage station, and relates to the technical field of water conservancy project equipment, the pressure water tank comprises a water tank main body, a sealing top cover, a valve and a sealing flange, the top of the water tank main body is in threaded connection with the sealing flange, the sealing top cover is fixedly mounted at the top of the sealing flange, and the valve is arranged at the top of the sealing top cover. When the outer side of a sealing top cover is subjected to extrusion acting force, a pressing plate is matched to press a telescopic pressing column, and an air bag cushion is compressed, so that internal air pressure moves towards the two sides, a stretching rod is pushed to move, and therefore a sleeving plate is pushed from bottom to top to move upwards, and the sleeving plate drives a springback column to stretch while ascending; the acting force is buffered and consumed through the elasticity of stretching of the rebound columns, the buffering protection function is achieved, the problems that the protection performance of the pressure water tank is poor, and a valve opening is prone to being damaged under the influence of external force are solved, the protection function of the device is increased, and the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering equipment, in particular to a pressure water tank for waterlogging stations of water conservancy projects. Background technique [0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and rejuvenating profits. Also known as water engineering. Water is an indispensable precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's life and production for water resources. Water conservancy projects need to build different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, canals, rafts, and fishways to achieve their goals. There are followin...

Problems solved by technology

[0005] The invention provides a pressurized water tank for drainage stations of water conservancy projects, one purpose of which is to have the function of increasing the sealing performance and solve the problem that the poor sealing performance of the pressurized water tank easily leads to internal air pressure leakage, thereby affecting the convenient use of the device; wherein Another purpose is to solve the problem that the protection performance of the pressure water tank is poor, and it is easy to damage the valve port under the influence of external force, resulting in the reduction of the service life of the pressure water tank, so as to increase the strength and improve the protection function of the device.
