Description
Technical field
The utility model relates to a kind of supply equipment of tap water, is a kind of low discharge pressurize supply equipment specifically.
Background technology
For solving the problem of high-floor feedwater insufficient pressure, secondary water-supply water pump commonly used improves the pressure that supplies water, and for fear of produce negative pressure in the tap water pipe network, influences other user's waters in the pipe network, and existing secondary water-supply equipment mostly adopts non-negative pressure method of water supply.Utilize water tank to regulate the pressure of pipe network, avoid producing negative pressure.But because user's water is more frequent, when tap water pipe network pressure is not enough, the water pump frequent starting, stop, the water pump life-span is short, equipment running cost height.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, low cost of manufacture, the life-span is long, running cost is low low discharge pressurize supply equipment.
For achieving the above object, the utility model is by the following technical solutions:
Low discharge pressurize supply equipment described in the utility model, comprise and be connected on the online tank body of running water pipe, be connected the booster water pump on the tank body delivery port, be connected in parallel on the bypass pipe at booster water pump two ends, be connected on electromagnetic valve and bypass check (non-return) valve on the bypass pipe, the upper end of tank body is provided with the tank body vacuum suppresser, it is characterized in that: be in series with the low discharge water pump on the described tank body water inlet, the two ends of low discharge water pump are parallel with the inlet bypass pipe, be in series with inlet electromagnetic valve and inlet check (non-return) valve on the inlet bypass pipe, be provided with the low discharge vacuum suppresser at the water inlet place of low discharge water pump.
After adopting technique scheme, water inlet and delivery port at tank body respectively are provided with a cover water pump supercharging equipment, adopt the low discharge water pump at the water inlet place, at any time supplementary pressure in tank body, be particularly suitable under the few situation of user's water, avoid the feed pump frequent starting at delivery port place, prolong the application life of feed pump, help reducing the running cost of equipment.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
As shown in drawings, low discharge pressurize supply equipment described in the utility model comprises and is connected on the online tank body of running water pipe 1, be connected the booster water pump 3 on tank body 1 delivery port, be connected in parallel on the bypass pipe 4 at booster water pump 3 two ends, be connected on electromagnetic valve 5 and bypass check (non-return) valve 6 on the bypass pipe 4, the upper end of tank body 1 is provided with tank body vacuum suppresser 7, be in series with low discharge water pump 8 on described tank body 1 water inlet, the two ends of low discharge water pump 8 are parallel with inlet bypass pipe 9, be in series with inlet electromagnetic valve 10 and inlet check (non-return) valve 11 on the inlet bypass pipe 9, be provided with low discharge vacuum suppresser 12 at the water inlet place of low discharge water pump 8.The delivery port of booster water pump 3 and bypass check (non-return) valve 6 is connected to the tap water user side.Booster water pump 3 and electromagnetic valve 5 are subjected to the control of automatic control circuit 13.When the sensor that is installed in the tap water user side detects the hydraulic pressure of user side satisfactory the time, booster water pump 3 is not worked, and electromagnetic valve 5 is opened, and tap water enters user pipe by bypass pipe 4; When the hydraulic pressure that detects user side when sensor was lower than designing requirement, electromagnetic valve 5 cut out, and booster water pump 3 is started working, and improves user side hydraulic pressure.Tank body vacuum suppresser 7 is installed in the top of tank body 1, when the tap water pipe network supplies water abundance, is full of water in the tank body 1, and tank body vacuum suppresser 7 closures make to keep certain pressure in the tank body 1; In the time of tap water pipe network insufficient water, the water in the tank body 1 replenishes, and tank body vacuum suppresser 7 is opened, and avoids the tap water pipe network to produce negative pressure.The structure of tank body vacuum suppresser 7 is a known technology, no longer is described in detail at this.
Low discharge water pump 8 can be little in user side discharge, the pressure in the tank body 1 reduces under few situation supplementary pressure in tank body 1 at any time, make the pressure in the tank body 1 keep constant as far as possible, reduce the number of starts of booster water pump 3, thereby can effectively prolong the application life of booster water pump 3, reduce the running cost of equipment.Low discharge water pump 8 and inlet electromagnetic valve 10 are subjected to the control of automatic control circuit 13.When tank body 1 inner sensor detects hydraulic pressure satisfactory the time, low discharge water pump 8 is not worked, and inlet electromagnetic valve 10 is opened, and tap water enters tank body 1 by inlet bypass pipe 9; When the hydraulic pressure in sensor detects tank body 1 was lower than designing requirement, inlet electromagnetic valve 10 cut out, and low discharge water pump 8 is started working, and improves the hydraulic pressure in the tank body 1.Low discharge vacuum suppresser 12 is installed in the water inlet place of low discharge water pump 8, and when the tap water pipe network supplied water abundance, tank body vacuum suppresser 7 closures prevented to leak; In the time of tap water pipe network insufficient water, tank body vacuum suppresser 7 avoids the tap water pipe network to produce negative pressure.
The structure of automatic control circuit 13 and operating principle are known technology, do not repeat them here.
