Description

The incremental supply equipment of two intelligent pipe network superchargings
The utility model relates to a kind of incremental supply equipment of water supply pipe secondary pressurization that is used for.
Rise along with highrise building, original municipal tap water ductwork pressure can not be satisfied the demand, extensively adopts second pressure water supply equipment for this reason, at present, the type of this equipment has two kinds: first tubing pump pressurization supply equipment, it two is water tank-high building pump pressurization supply equipments.The former directly is serially connected in water pump (referring to all kinds of water pumps) on the water supply pipe, when the flow that uses as the user surpasses the flow that tap water can provide, the water inlet of water pump will produce suction (negative pressure) and influence water supply pipe uses the normal water that encloses the user, therefore except that special circumstances, Running-water Company does not generally allow to adopt such equipment.The latter is connected on (generally being by float valve water to be introduced in the water tank) on the water tank with water supply pipe, the exit of water tank is connected on the water pump water sucking mouth of (referring to all kinds of water pumps), supply water by the water pump pressurization then, though having suction (no negative pressure) to pipe network, this kind equipment is not subjected to the restriction of Running-water Company, and has certain water yield regulating power (promptly when user's water use peak, water tank discharges the water yield, when user's water low ebb, store the water yield), but wasted lot of energy because of original pressure of pipe network can't utilize.Therefore, develop a kind of original exert pressure of pipe network of can utilizing and supply water, the supply equipment that again pipe network is not constituted suction and have and handle up (store or discharge) certain water yield when supplying water has been the task of top priority.
The purpose of this utility model provides a kind of new incremental supply equipment of intelligent supercharging, it not only is not subjected to the restriction of Running-water Company on the net because of the equipment water inlet has the running water pipe that suction can directly be connected on any insufficient pressure to pipe network, and has incremental double action of supercharging and Remarkable Energy Saving advantage.
For reaching this purpose, the technical scheme that is adopted is at the water inlet of existing water pump installing flap valve and motor-operated control valve, the delivery port of the voltage stabilizing water storage box of putting through another flap valve and height between flap valve and water pump links to each other, liquid level sensor is equipped with in the inside of voltage stabilizing water storage box, the water inlet of voltage stabilizing water storage box is introduced the water source by float valve by water supply pipe, adjusts the rotating speed of water pump to reach the constant of equipment outlet pressure with microcomputer control cabinet control and frequency conversion.
The utility model has the advantages that: 1, because of water supply pipe not being had swabbing (no negative pressure) so can be serially connected on any water supply pipe, the scope of application is unrestricted; 2, because of making full use of the pressure obvious energy conservation of tap water pipe network; 3, not only have pressurization function, but also have the effect of incremental (discharging the stored water yield); 4, adopt two intelligent microcomputer controlled variable-frequency speed-regulating constant pressure water supplies, energy-conservation further raising.
Below in conjunction with the drawings and the specific embodiments, the utility model is described further.
Figure one is the utility model aufbauprinciple schematic diagram.
Figure one is the utility model aufbauprinciple schematic diagram.It is constructed by voltage stabilizing water storage box 1, float valve 2, liquid level sensor 3, water pump 4, teletransmission pressure meter 5, flap valve 6, flap valve 7, flap valve 8, pressure vacuum gauge 9, compositions such as microcomputer control cabinet 10 and motor-operated control valve 11.Its operating principle is as follows:
1, as the employed flow Q of user WithLess than the flow Q that water supply pipe provided NetThe time, the unnecessary water yield is just closed until the full float valve 2 of water in float valve 2 enters the voltage stabilizing water storage box 1 that height puts, so the pressure of the water inlet of water pump 4 rises the pressure value P of ordering as O rapidly 0During greater than the inlet pressure of flap valve 6, flap valve 6 cuts out, and flap valve 8 is opened, and this moment, water pump 4 was directly from water supply pipe supply water (we can be referred to as tubing pump water supply state).Obviously, the reading of Ci Shi pressure vacuum gauge 9 is positive number (equaling the pressure of tap water pipe network, generally more than 0.1MPa).
2, if the flow Q that the tap water pipe network can provide NetLess than the employed flow Q of user With, the pressure that this moment, O was ordered descends rapidly, opens under the effect of flap valve 6 gravity pressure of water in voltage stabilizing water storage box 1, to replenish the difference of the above-mentioned water yield.At this moment, the existence of water in the voltage stabilizing water storage box of putting because of height 1 can make force value that O orders all the time greater than zero.So the force value of pressure vacuum gauge 9 is always on the occasion of (water inlet that is this equipment is always on the occasion of state).
Learn by 1 and 2: no matter be Q WithGreater than Q NetOr Q WithLess than Q NetThe reading of the pressure vacuum gauge 9 of the water inlet of this equipment is all the time greater than zero, and therefore we can say: this equipment had both made full use of the pressure of water supply pipe, again water supply pipe was not constituted suction (no negative pressure), reaches best energy-saving effect.
3, the liquid level sensor among the figure 3 is used to send that the liquid level position signal uses; be divided into the upper limit; middle limit and lower limit; when being reduced to down, the water level of voltage stabilizing water storage box 1 sends the termination of pumping signal in limited time; when returning to, the water level of voltage stabilizing water storage box 1 sent the pump signal in limited time; so that water pump 4 enters normal operating condition, play the effect of protection water pump.Sequence number 4 is seen in the effect of middle limit.
4, because the uncertainty of tap water pipe network flow and user's water supply volume, if Q Net>Q WithOverlong time, the water that then is stuck in the voltage stabilizing water storage box 1 will overlong time, make the water quality variation, for this reason, the spy is installed motor-operated control valve 11 additional between A point and O point, limit occurrence number at the appointed time in the microcomputer record liquid level face, if reach requirement, then microcomputer control cabinet 10 automatic control motor-operated control valves 11 are closed, therefore, water pump 4 will be fetched water from voltage stabilizing water storage box 1, thereby avoids the disadvantage of voltage stabilizing water storage box 1 inner storing water overlong time.
5, for varying speed and constant pressure feed water equipment, its energy-saving principle was done in interrelated data in detail and was introduced, and stressed that here this equipment is in tubing pump water supply state (this moment Q NetGreater than Q With) time adopt the energy-saving principle and the process thereof of varying speed and constant pressure feed water.
If the outlet pressure of this equipment setting value is P If, the pressure P in water supply pipe FromLess than P IfThe time microcomputer controlled variable-frequency speed-regulating (speedup) operation water pump 4, up to the pressure P of the teletransmission pressure meter 5 in equipment exit Table=P IfThe time, microcomputer controlled variable-frequency speed-regulating water pump 4 is with constant rotation speed operation.P FromHigh more, P If-P FromDifference more little, the actual speed of microcomputer control of pump 4 is just more little; Otherwise, P FromLow more, P If-P FromDifference big more, the actual speed of microcomputer control of pump 4 is just high more.Therefore not only guarantee outlet pressure constant of equipment but also made full use of the pressure of water supply pipe, reached best energy-saving effect.
6, when user's power supply had a power failure, the current of water supply pipe were being filled with voltage stabilizing water storage box 1 back (this moment, float valve 2 was closed), and the just automatic bypass duct through having flap valve 7 of current supplies water to the user.The effect of flap valve 7 is only to allow current from the water supply pipe user that flows through, and does not allow reverse flow.
7, the effect of flap valve 8 is when tap water cut-off, prevents that the retaining in the voltage stabilizing water storage box 1 from entering in the water supply pipe.
8, because the utility model is selected two kinds of duties (tubing pump water supply state and water tank-water pump water supply state) of equipment automatically according to the pressure of tap water pipe network, and every kind of duty all adopts microcomputer controlled variable-frequency speed-regulating constant pressure water supply technology, so be referred to as two intelligent supply equipments
