Pipe network residual pressure utilization device

technical field

The utility model relates to a pipe network residual pressure utilization device.

Background technique

With the development of urban construction scale, the number and scale of high-rise buildings and small high-rise residential quarters in the city continue to increase, the market for secondary pressurized water supply equipment is growing, and frequency conversion speed regulation pressurized water supply equipment is widely used. This secondary pressurization method is to absorb water in the water storage tank, and then pressurize the water to the pre-set high-rise residential buildings by the frequency conversion speed regulation pressurized water pump. When the water pump is working, the urban pipe network will continuously discharge to the water storage tank. Pressure replenishment, the original pressure in the pipe network can be wasted in vain.

Contents of the invention

The purpose of this utility model is to overcome the disadvantages mentioned above and provide a pipe network residual pressure utilization device composed of a water pipe network, a reservoir, a pressurizing pump and a water pipe network pressure mixer. It can make full use of a large amount of water pressure difference wasted in the pipe network, that is, the nozzle injects the pressure water introduced into the pipe by the pressure source at a high speed at the peak of water consumption, and sends it into the water pump together with the water in part of the reservoir The water suction end is pressurized. When the water consumption is at a low peak, due to the non-return function of the non-return valve installed in the pressure mixer of the water delivery pipe network, a certain pressure is formed in the residual pressure utilization device, so the water pump The reduction of the rotating speed will greatly reduce the power consumption of the water pump and achieve the purpose of saving electricity.

The utility model is realized in this way. It is composed of a water delivery pipe network, a water storage tank and a pressurized pump. It is characterized in that a water delivery pipe network pressure mixer is set between the water storage tank and the pressurized pump. The network pressure mixer is composed of a shell, a pressure source introduction pipe arranged on the upper part of the shell, and an anti-backflow device connected to the shell of the water delivery pipe network pressure mixer. The valve of the reservoir is connected with the anti-backflow device and is located One end of the pressure source introduction pipe on the upper part of the water delivery pipe network pressure mixer shell is connected to the external water delivery pipe network, and the other end extends into the casing to be threadedly connected to the injection nozzle in the pressure outlet end, and is connected to the center of the suction port inlet of the booster pump. corresponding to the line.

The gist of the present invention is also that the anti-backflow device adopts a check valve, the bracket and the check valve seat of the check valve are fixed on the check valve housing, and the check valve disc and the reset spring are mounted on the bracket. and between the check valve seat.

The utility model has the advantages that: due to the adoption of the above structure, the original pressure in the pipe network is used to increase the water inlet pressure of the frequency conversion speed regulating water pump, thereby reducing the power consumed by the water pump and the consumption of electric energy; when the water consumption is low peak At this time, due to the non-return function of the non-return valve installed in the pressure mixer of the water delivery pipe network, a certain pressure is formed in the residual pressure utilization device, so the speed of the water pump is reduced, and the power consumption of the water pump is greatly reduced. , to achieve the purpose of saving electricity, thereby effectively utilizing the pressure of the pipe network and saving energy.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

Referring to accompanying drawing 1, the utility model is made up of water delivery pipe network, reservoir and pressurization pump, is characterized in that a water delivery pipe network pressure mixer 2 is established between reservoir 5 and pressurization pump 1, and its The water pipe network pressure mixer 2 is composed of a housing 2-3, a pressure source introduction pipe 2-2 arranged on the upper part of the housing 2-3 and an anti-corrosion pipe connected to the housing 2-3 of the water pipe network pressure mixer 2 The backflow device is composed of the valve 4 of the reservoir 5 connected to the anti-backflow device, and one end of the pressure source introduction pipe 2-2 on the upper part of the water delivery pipe network pressure mixer 2 housing 2-1 is connected to the external water delivery pipe network 3 , the other end extends into the housing 2-1 and is threadedly connected with the spray nozzle 2-5 in the pressure outlet port 2-1, and corresponds to the central line of the suction port inlet of the booster pump 1. Its described injection nozzle 2-5 preferably makes conical structure, so that produce good jet effect.

The anti-backflow pollution of the utility model generally adopts a check valve, and the bracket 2-6 and the check valve seat 2-9 of the check valve are fixed on the check valve housing 2-4, and the check valve disc 2-8 And back-moving spring 2-8 is contained between support 2-6 and check valve seat 2-9. When the water is at its peak, the spray nozzle will introduce the pressure source into the pressure water in the pipe 2-2 to spray out at a high speed, and send it to the suction end of the water pump together with part of the water in the reservoir 5 for pressurization, which provides a part of energy for the water pump 1 , reducing the load of the water pump 1, achieving the effect of energy saving, and driving the flow of water in the reservoir, avoiding the deterioration of the water in the reservoir; when the water consumption is low, the water provided by the device exceeds the water supply system When measuring, due to the anti-backwater check valve is set in the pressure mixer of the water delivery network, pressure will be generated in the shell of the pressure mixer of the water delivery network, and under the action of this pressure, the check valve disc will be pushed Move to the right, closing off the access to the cistern. The remaining water will not return to the reservoir, effectively preventing the reservoir from overflowing. At this time, the pressure in the housing of the pressure mixer in the water delivery pipe network reduces the lift that the water supply pump needs to provide, and the speed of the water pump decreases, which greatly reduces the power consumption of the water pump and achieves the purpose of saving electricity.
