Background technology
In the prior art, in order to solve in the tap water pipe network needs to the highrise building water, adopt storage tank or reservoir mode to come grid and tap water water pipe network to isolate in tap water, thereby make the influence that can not come grid generation negative pressure in user's water supply process tap water.But this mode is seriously polluted to water, therefore adopts the scheme of removing storage tank or reservoir, comes grid to be connected in variable frequency pump and tap water, by pressure control, realizes that pipe network does not have negative pressure.But, adopt this technical scheme after, when tap water came the grid water shortage, the switching of compensating tank electrically-controlled valve in the work of compensating was very slow, often occurred incuring loss through delay phenomenon, caused water pump to damage easily, had had a strong impact on user network.In addition, because compensation water hypertonia when the supply variable frequency pump does not meet the variable frequency pump working condition requirement, has also influenced the quality of water supply of tap water water pipe network simultaneously, even can impact to variable frequency pump itself, have influence on the safety and the application life of variable frequency pump.
The utility model content
The purpose of this utility model provides a kind of decompression compensation water supply installation, it can come the situation of grid and user network according to tap water, compensate, not only can keep tap water to come the basic pressure of grid all the time, and in case when tap water water ductwork pressure occurring and descending, water supply rapidly can afford redress, safeguard the stable of tap water water pipe network water pressure, the water supply that meets variable frequency pump working condition pressure compensation is provided, guaranteed variable frequency pump safety, improve user's quality of water supply, to remedy the deficiencies in the prior art.
The technical scheme that the utility model addresses the above problem employing is: a kind of decompression compensation water supply installation; it comprises variable frequency pump; the water supply compensating tank; pressure sensor and control circuit; described variable frequency pump two ends come grid to be connected with tap water water pipe network with tap water respectively through tube connector; described pressure sensor is arranged on described tap water to come on the described tube connector that grid links to each other; it also comprises the compensating tank bypass pipe; be arranged on the automatically controlled joint door of bypass pipe on the described compensating tank bypass pipe; compensating tank connecting leg and be arranged on the reducing valve that is used to protect described variable frequency pump on the described compensating tank connecting leg; described compensating tank bypass pipe two ends are connected with described tap water water pipe network with described water supply compensating tank respectively; described compensating tank connecting leg one end is arranged on described tap water and comes on the described tube connector between grid and the described variable frequency pump; the other end is connected with described compensating tank bypass pipe, and the automatically controlled joint door of described bypass pipe is connected with described control circuit by electric wire with described pressure sensor.
Also be provided with the automatically controlled joint door of the compensating tank that is electrically connected with described control circuit on the described compensating tank connecting leg.
During use, tap water comes grid pressure just often, and the automatically controlled joint door of bypass pipe is in open mode, and variable frequency pump work is carried out water yield compensation to tap water water pipe network and water supply compensating tank; When tap water came grid pressure to hang down, pressure sensor sent signal and gives control circuit, and the automatically controlled joint door of bypass pipe is closed, and at this moment, the reducing valve low-pressure end is lower than 2kg, and the water in the water supply compensating tank flows out by the compensating tank connecting leg, and tap water water pipe network is compensated; Night the user water supply volume more after a little while, variable frequency pump quits work, current replenish through the compensating tank bypass pipe and enter in the tap water water pipe network in the water supply compensating tank, compensate.
The utility model decompression compensation water supply installation beneficial effect is: pass through the technical program, can automatically come grid to continue water yield compensation to tap water, can also play the effect of voltage stabilizing compensation to tap water water pipe network, to guarantee that tap water comes grid not produce negative pressure, eliminate the Fraquent start phenomenon of variable frequency pump, reduce the number of starts of variable frequency pump, under the water supply compensating tank of equal volume, improved the water supply compensation ability greatly.
