Pressure-stabilizing flat-plate overflow valve for high-rise water supply of smart city

Abstract

The invention discloses a pressure-stabilizing flat-plate overflow valve for high-rise water supply of a smart city, and particularly relates to the field of smart cities. The pressure-stabilizing flat-plate overflow valve comprises a pressure-stabilizing overflow valve body and a control valve element, the pressure-stabilizing overflow valve body comprises a valve body and a control valve deck, and a liquid inlet end hole, a motion valve cavity and an overflow end hole are formed in the valve body; a motion sensing assembly, a control assembly and a hydraulic return assembly are fixedly installed in the pressure stabilizing overflow valve body, an abutting locking assembly is fixedly installed on the top surface of the control valve element, the top surface of the control valve element is fixedly connected with the end of the hydraulic return assembly, and a motion locking assembly is movably installed on one side of the motion sensing assembly. According to the scheme, a pressure measuring structure is arranged in the overflow valve, that is, the motion sensing assembly and the pressure sensing assembly are used for measuring the pressure of the front end of the valve and the flow hydraulic pressure respectively, the working power of a pump machine is changed through electric signals, pressure adjustment of the whole pipeline structure is completed, no extra pressure relief pipeline is required to be arranged, and the practicability of the valve body is improved.

Description

technical field [0001] The invention relates to the technical field of smart cities, and more specifically, the invention is a pressure-stabilizing plate overflow valve for high-rise water supply in smart cities. Background technique [0002] Due to the continuous increase of high-rise buildings, in order to meet the normal daily water supply of high-rise residents, secondary water supply equipment directly connected in series with the municipal water supply network came into being. After storage and pressurization, it is the only choice for high-rise water supply through pipelines for users or self-use. Whether the secondary water supply equipment is constructed according to the regulations, whether the design and construction are good or bad is directly related to the quality and pressure of the secondary water supply. It is closely related to the safety of water supply and the normal and stable life of the people. The principle of modern water supply equipment is to furth...

Problems solved by technology

[0003] With the development of computers and the advent of the information age, the existing urban high-rise water supply process has put forward the management of "informatization, digitalization, and modularization" for urban water supply, and the unattended smart pump room has been continuously improved and perfected. The flow valve is widely used in the secondary water supply of the smart pump room, that is, the hydraulic pressure of the pipeline is stabilized through the overflow valve. When the water pressure passing through the pipeline structure exceeds the set pressure, the circuit is opened by pressure to discharge the liquid. In this way, a safe and non-overpressure pipeline can be controlled to protect the pipeline structure at the rear end. However, the existing relief valve structure needs to be equipped with an independent pressure relief pipeline structure, which leads to cumbersome pipeline layout and troublesome installation. Leakage and other issues

[0004] In addition, in the throttling adjustment system of the pump room, the constant flow pump provides continuous flow. When the system pressure increases, the flow demand will decrease. At this time, the overflow valve will open to make the excess flow overflow back to the water tank to ensure the overflow. The inlet pressure of the valve, that is, the outlet pressure of the pump is constant (the valve port is often opened with the pressure fluctuation). During the working process, due to the fluctuation of the water pressure in the pump room, it is easy to cause the abnormal fluctuation of the pipeline pressure to the pressure of the valve core, resulting in the movement of the valve core, which has a great influence on the pressure of the rear pipeline, and has no pressure stabilizing effect. Can not provide effective protection for the back-end pipeline, there are certain defects
