Voltage-compensating water supply installation and method without additional infection of common ductwork hydraulic pressure

Abstract

The present invention discloses a pressure-compensating water-supplying device which does not additionally affect the hydraulic pressure of the common ductwork. The device comprises the following components: at least one equipment body, a water inlet valve, a water outlet valve, a bypass one-way valve, a first and a second ventilation valves, a low pressure restraining instrument (8), a water shortage protective device, a water discharging pressure sensor and at least one control device. The method comprises the steps of detecting the pressures of the water inlet valve and the water outlet valve by the control device through the low pressure restraining instrument and the like for generating the data information of the water pressure of the water inlet valve and the water outlet valve and the like, and transmitting the information to the control device through the signal cable for controlling. The device uses a totally sealed electric underwater pump to directly take water from the common ductwork for pressurization without the water pool, the water tank or the voltage stabilization of the voltage stabilization pot. The invention has the advantages of realizing voltage-stabilizing water supply without additionally reducing the pressure of the common ductwork, no pollution to the water quality, automatic running, more energy-saving and earth-saving.

Description

technical field [0001] The invention relates to a pressurized water supply device, more particularly to a pressurized water supply device and method that do not additionally affect the water pressure of a public pipe network. Background technique [0002] Since the patent number is 98220256.3 and the invention name is "pressurized water supply tank" patent authorization, the "JS series pressurized water supply device" has been developed accordingly. In 2002, the Ministry of Construction and the Ministry of Science and Technology approved the "JS device" as a scientific and technological achievement promotion project and a national key promotion of scientific and technological achievements plan project. Now dozens of similar products have been put on the market, and the secondary pressurized water supply for pollution prevention and energy saving Technology is developing rapidly. However, it still stays at the technical stage of anti-negative pressure and no negative pressur...

Problems solved by technology

This is a common concern, and it is also an important reason why it is difficult to fully promote the technology

In addition, just to prevent negative pressure, the water head of 20 meters and 30 meters in the municipal pipe network cannot be fully utilized; the power of the pressurization equipment must be increased; it also increases the difficulty of installing and antifreezing the surge tank, which is not conducive to energy saving and environmental protection
