Water drawing system

Abstract

The invention relates to a water drawing system. The water drawing system comprises a water pump, a circulating water pipe, a positive-negative pressure connection tank and at least one valve port; the input end of the water pump is connected with a water source through a pipeline; the output end of the water pump is connected with the input end of the circulating pipe; a floating one-way valve isarranged in the positive-negative pressure connection tank, the output end of the circulating water pipe penetrates through the positive-negative pressure connection tank to be in communication withan inlet of the floating one-way valve; the input end of the water pump is also in communication with the positive-negative pressure connection tank through a pipeline; and the at least one valve portis arranged on the circulating water pipe. According to the water drawing system, the proper floating one-way valve is arranged to serve as a meson to be matched and coordinated with the operation conditions of all valve ports of the circulating water pipe, pressure guarantee in the circulating water pipe and all the valve ports is achieved, and after the pressure in the circulating water pipe meets the requirements of all the valve ports, water can enter the positive and negative pressure connection tank through the floating one-way valve, the pressure and water supply of the system are ensured to be proper, the working efficiency of the water drawing system is greatly improved, and the energy-saving purpose is further achieved.

Description

technical field [0001] The invention relates to the technical field of water resource supply, in particular to a water drawing system. Background technique [0002] In the world and in my country, agricultural and forestry irrigation, urban greening, and different industries that are relatively dependent on water sources in areas where fresh water resources are relatively scarce require water pumping systems for irrigation, and the irrigation process requires effective use of water resources. The supply requirements are just right, that is, the water supply of the system meets the demand and achieves the purpose of saving energy. [0003] In terms of water resources allocation, the consumption of the water drawn and supplied from the water source by the pump body is all consumed on the pipeline along the line, at the valve port set at a specific distance. Whether the pressure of the system is just right determines whether the water supply is just right and whether the water ...

Problems solved by technology

The water supply process of the existing water drawing system cannot control its system pressure, and it is prone to excessive pressure or too low pressure, which will cause the contradiction of excessive load or insufficient water pressure in the system. Therefore, it is necessary to provide a water drawing system to solve the problem. The above contradiction
