No negative pressure water supply equipment mostly traditional mechanical breather valve is used to eliminate the negative pressure, eliminate action lags behind the formation of action; While vertical mute type products by preloading self-balancing type vacuum suppressor and intelligent microcomputer system to suppress the formation of negative pressure. At the same time, the new product is equipped with structure more reasonable and easy to manufacture the balanced steady flow can compensate for storage, through to absorb or release energy, effectively restrain an instant flow pressure, steady flow regulator, make sure that there is no any impact on the municipal pipe network. In addition, the vacuum suppressor breathing condition and opening and closing is through the detection and feedback of functional components, and the switch quantity is transmitted to the microcomputer, microcomputer again through the inverter to adjust water pump speed, make the pump suction is equal to the amount of municipal pipe into the water, forming the second line of defense security of water supply. Also, vacuum suppressor with air filtration membrane, effectively intercept dust bacteria influence on water quality, prevent the water from ambient air pollution; Wade parts material selection of food grade stainless material, also can eradicate corrosion pollution.
No negative pressure water supply equipment, supply without negative pressure tank assembly, vacuum suppressor, can use waterproof drops electrode, cans with underneath type water level switch, energy storage type vacuum preloading suppressor, built-in eliminate negative pressure, and flow rate balance accessories, achieve uninterrupted water supply when the height of water in and out of traffic imbalance, to ensure network security and user interests.
