No negative pressure is used vacuum inhibition technology, to solve water supply facilities and municipal pipeline concatenated may produce negative pressure, the influence of to prevent the occurrence of the Q in the peak time of water using > Q condition, from the overlying relay mode to compensate the transfer of water absorbing state process caused by the pressure imbalance, to ensure that the municipal pipe network safe operation.



Health level has no negative pressure water supply equipment, is made of stainless steel pumps, stainless steel steady flow compensator and health level of valve pipe fittings



Steady flow compensator is an essential part of no negative pressure water supply device, can be divided into open compensation and preloading compensation. Mainly by the steady flow compensation tank, vacuum of suppressor and water shortage protection control components.



Open type vacuum suppressor can be divided into general vacuum suppressor, lever type vacuum suppressor and leveraged cylinder type vacuum suppressor.



pre



Overlying, no negative pressure is synonymous with prove significance, it broke the bondage of traditional thinking and systematic process, has a far-reaching influence on energy conservation and environmental protection high quality water supply, the so-called "important" is composed of variable frequency pump directly from the municipal water supply network concatenated pressurization water supply mode, make full use of the water supply pipe network pressure, reduce the pump head, save electricity, so as to solve the traditional water supply pressure from scratch, a waste of energy, pollution and so on.



Pressure type vacuum suppressor for digital, fully sealed, preloading, energy storage, since the balance
