Novel totally-closed negative-pressure-preventing secondary water supplying system with suppressor

Abstract

The invention discloses a novel totally-closed negative-pressure-preventing secondary water supplying system with a suppressor. The secondary water supplying system comprises water pumps, a flow stabilizing tank, a pressure meter, the suppressor, an air pressure tank, electromagnetic valves, a matched grid system and a matched water transportation pipe network system, and is characterized in that the water pumps are provided with induction air stopping switching valves, the flow stabilizing tank is provided with an induction type liquid level floating ball and a three-way air exhausting meter valve, the three-way air exhausting meter valve is directly connected with the pressure meter, the pressure meter is provided with a numerical display screen and an alarm device, the suppressor is provided with a pressure transmitter and a liquid level switch, the air pressure tank is provided with a power-connection type digital display pressure meter, and the matched grid system is provided with the three electromagnetic valves. The secondary water supplying system has the characteristics of total closing, negative pressure preventing, induction alarming, automatic air discharging, automatic water-supplementing pressure stabilizing, automatic water changing and dead water preventing; the scheme is suitable for mass use of the secondary water supplying system for production and domestic municipal water supplying to people.

Description

technical field [0001] The invention relates to the field of secondary water supply systems, in particular to a secondary water supply system of a novel fully enclosed anti-negative pressure suppressor. Background technique [0002] When the municipal water supply system is supplied to people's production and life, it usually needs to be equipped with a secondary water supply system to ensure normal use. The general components of the ordinary secondary water supply system are: water pump, air pressure tank, steady flow tank, exhaust valve, vacuum suppressor, pressure gauge, supporting water pipe network system and supporting power grid control system. When using the ordinary secondary water supply system, the following problems often occur: 1. It cannot be guaranteed to be completely closed, and secondary pollution often occurs; 2. When there is a short-term municipal water supply cut-off, stagnant water will occur, and the water cannot be changed automatically ; 3. When th...

AI Technical Summary

Problems solved by technology

When using the ordinary secondary water supply system, the following problems often occur: 1. It cannot be guaranteed to be completely closed, and secondary pollution often occurs; 2. When there is a short-term municipal water supply cut-off, stagnant water will occur, and the water cannot be changed automatically ;3. When the water level of the steady flow tank is too low, the alarm cannot be reminded; 4. After the water level of the steady flow tank is lowered, when the water level of the steady flow tank rises again, it cannot be exhausted automatically, and manual exhaust is required
