Non-negative-pressure water supply equipment

Abstract

The invention discloses non-negative-pressure water supply equipment. The non-negative-pressure water supply equipment comprises a steady flow compensator, a vacuum suppressor mounted at the upper end of the steady flow compensator, a water inlet pipe mounted above the steady flow compensator, a pressure sensor mounted above the steady flow compensator and a blowdown valve mounted below the steady flow compensator, wherein the water inlet pipe is communicated with a tap water pipe; a negative pressure meter, a valve, a filter and a backflow preventer are mounted on the tap water pipe; one end of the steady flow compensator is connected with a variable-frequency controller, the other end is connected with a pump set, a pressure transmitter and a diaphragm type pneumatic valve are mounted at one end of the pump set, and tap water is delivered to users. The steady flow compensator of the non-negative-pressure water supply equipment can compensate a municipal water supply pipeline for stable pressure in a negative pressure state, so that negative pressure in the municipal water supply pipeline is eliminated, stable water supply by the municipal water supply pipeline is realized.

Description

technical field [0001] The invention relates to the technical field of water supply equipment, in particular to a non-negative pressure water supply equipment. Background technique [0002] Water resources are an essential and important resource in people's lives, and high energy consumption in economic development has become an urgent problem to be solved in my country's industry and residents' lives. With the rapid development of energy-saving technologies, energy conservation and energy use costs are reduced. At the same time, problems such as water difficulties due to insufficient tap water pressure need to be resolved. [0003] At present, there is a kind of non-negative pressure water supply equipment on the market. It is a pressurized water supply unit directly connected to the municipal water supply pipe network, and the water supply is superimposed in series on the basis of the residual pressure of the municipal pipe network to ensure that the pressure of the municip...
