Description
1, technical field
The utility model relates to a kind of second pressure water supply system, and specifically a kind of and tap water water inlet pipe directly are connected in series the non negative-pressure water supply system of high position water-storing tank of pressurization.
2, background technology
At present, known non-negative pressure water service system can directly be concatenated into pressurization rear line feed pipe water supply on the tap water water inlet pipe, its distinguishing feature is original pressure that can make full use of the tap water water inlet pipe, system's energy saving in running, but because the non-negative pressure water service system of prior art has defectives such as system's volume adjusted is little, no water storage capacity, therefore, the prior art inflow that can not solve the tap water water inlet pipe does not well satisfy the water supply problem that the peak water requires or the tap water water inlet pipe is often cut off the water of user's feed pipe.
3, utility model content
For overcoming above-mentioned the deficiencies in the prior art, the utility model provides a kind of non negative-pressure water supply system of high position water-storing tank, this system can not only directly be connected in series pressurization with the tap water water inlet pipe, and can utilize the water storage capacity of elevated storage case to solve to cut off the water nextly, the inflow of power failure or tap water water inlet pipe is not enough and cause termination of pumping but do not influence the normal water of user's feed pipe.
The technical scheme that its technical problem that solves the utility model adopts is: non negative-pressure water supply system of high position water-storing tank is by the tap water water inlet pipe, backflow preventer, steady flow compensator and vacuum suppresser, water pump, the elevated storage case, switch board and user's feed pipe are formed, the tap water water inlet pipe is connected the back and links to each other with water pump with steady flow compensator and vacuum suppresser, pumping line is directly received on user's feed pipe, and connect the elevated storage case at the end of user's feed pipe, the outlet pipe of elevated storage case is connected with its water inlet pipe in elevated storage case bottom behind motor operated valve and flap valve, and in the elevated storage case, install fluid level controller, on steady flow compensator and the vacuum suppresser pressure sensor is housed, steady flow compensator and vacuum suppresser, water pump, pressure sensor, fluid level controller and motor operated valve are wired to switch board respectively, and the effect of installing flap valve at the outlet pipe of elevated storage case is in order to guarantee only export but no import.During normal water supply, system realizes directly being connected in series with the tap water water inlet pipe non-negative pressure method of water supply mode of pressurization by steady flow compensator and vacuum suppresser, water pump, switch board, and the frequency control of passing through water pump is directly supplied water to user's feed pipe, and the elevated storage case is by user's feed pipe automatic water supplement, and this moment, the motor operated valve of elevated storage case outlet pipe was in closed condition; Can not satisfy the peak water requirement of user's feed pipe when the inflow of tap water water inlet pipe, and when exceeding the no negative pressure adjustable range of steady flow compensator and vacuum suppresser, system shuts down by the switch board control of pump, at this moment, the motor operated valve of the outlet pipe of elevated storage case is opened automatically, supply water to user's feed pipe by the elevated storage case, to satisfy the water requirement, simultaneously, the tap water water inlet pipe is to steady flow compensator and vacuum suppresser moisturizing, with water storage capacity to pressure sensor detect to set open pump pressure the time, system starts water pump operation, when if the water that water pump still can not satisfy user's feed pipe at the inflow of postrun tap water water inlet pipe requires, water pump is out of service automatically again after operation a period of time, supply water so repeatedly, reach the peak water requirement of user's feed pipe, motor operated valve in this process is in opening all the time, system unites water supply by water pump and elevated storage case to user's feed pipe, when the water that can satisfy user's feed pipe at the inflow that detects the tap water water inlet pipe behind the water pump operation behind water use peak when pressure sensor requires, motor operated valve cuts out, at this moment, system directly supplies water to user's feed pipe by the non-negative pressure method of water supply mode, and to the moisturizing of elevated storage case.
Be to guarantee the water quality of storage water health in the elevated storage case, water storage after 48 hours the program of system by switch board the timed and forced water supply that realizes the elevated storage case is set.When forcing to supply water, open motor operated valve earlier, stop water pump again, at this moment, system is supplied water to user's feed pipe by the elevated storage case, when treating that the interior water storage drawdown of elevated storage case arrives the low water stage of fluid level controller control, starting mode of pump, and behind the operation certain hour, motor operated valve cuts out automatically, and normal water supply recovers in system.
The beneficial effects of the utility model are, end at user's feed pipe of the non-negative pressure water service system that directly is connected in series with the tap water water inlet pipe is provided with the elevated storage case, and by switch board, motor operated valve, fluid level controller and pressure sensor realization control automatically, can guarantee effectively because of cut off the water, the inflow of power failure or tap water water inlet pipe causes termination of pumping inadequately but do not influence the normal water of user's feed pipe, system water supply is reliable, and energy saving in running, hygienic quality is good, the automaticity height.
