Box-type pressurized water supply equipment with high-efficiency water distributor

technical field

The utility model relates to a water supply device, in particular to a box-type pressurized water supply device with a high-efficiency water distributor.

Background technique

When the water supply pressure of high-rise buildings is insufficient, the water pump is usually used to pressurize the water supply; in the water supply equipment that uses the water pump to pressurize the water supply, in order to avoid negative pressure in the municipal pipe network, it is usually necessary to set up a storage tank between the municipal pipe network and the community water supply pipe. Energy stabilizing tank and negative pressure compensator; the high-rise water supply equipment used in combination with energy storage stabilizing tank and negative pressure compensator is very widely used, but because all the water flow must pass through the energy storage stabilizing tank, the pump works for a long time , The load is large, the overall structure is complex, and the cost is expensive. The place where the water is stored, such as the energy storage steady flow tank, is prone to deposit dirt, and secondary pollution is likely to occur during the water supply process. the

Contents of the invention

The purpose of the utility model is to provide a box-type pressurized water supply device with a high-efficiency water distributor, which has a simple structure, does not need a negative pressure compensator, is low in cost, and reduces secondary pollution.

The technical scheme that the utility model adopts for solving the technical problem is:

The box-type pressurized water supply equipment with a high-efficiency water distributor described in the utility model includes a water pump unit arranged between the municipal pipe network and the user pipe network, and a mixed flow tank and a water tank are arranged at the front end of the water pump unit. The tank is a sealed tank with at least two water inlets and a mixed water outlet. The water tank has at least one water inlet and one water outlet. Connection, the inner end of the water inlet pipe is located in the inner cavity of the water tank, and a float valve is installed at the inner end of the water inlet pipe; one water inlet of the mixed flow tank is connected to the municipal pipe network through a pipe, and the water outlet pipe set on the water outlet of the water tank is passed through an increaser. The pressure pump is connected to another water inlet of the mixed flow tank, and the mixed water outlet of the mixed flow tank is connected to the input end of the water pump unit. It is characterized in that: a water distributor is provided at the bottom of the inner cavity of the water tank, and the water distributor includes a cross setting Annular pipes, straight pipes, and connecting pipes on the same plane, the intersecting parts of the annular pipes, straight pipes, and connecting pipes communicate with each other, and there are multiple through holes evenly distributed on the annular pipes and straight pipes. Water connection.

After adopting the above technical scheme, the water distributor draws water from different parts of the water tank, avoiding stagnant water in other parts caused by one point of water intake, preventing the precipitation of solid impurities in the water tank, and effectively avoiding secondary water supply pollution; at the same time, the box-type pressurized water supply equipment Negative pressure can be avoided in the municipal pipe network without the need for a negative pressure compensator, and the structure is simple and the production cost is low.

Detailed ways

As shown in Figure 1, the box-type pressurized water supply equipment with a high-efficiency water distributor described in the utility model includes a water pump unit 18 arranged between the municipal pipe network 1 and the user pipe network 20, and at the front end of the water pump unit 18 A mixed flow tank 15 and a water tank 9 are provided. The mixed flow tank 15 is a sealed tank body with at least two water inlets and a mixed water outlet. The water tank 9 has at least one water inlet and a water outlet 92. The outer end of the water inlet pipe 91 on the water inlet pipe mouth of the water tank 9 is connected with the municipal pipe network 1, and the inner end of the water inlet pipe 91 is positioned at the inner cavity of the water tank 9, and the inner end of the water inlet pipe 91 is equipped with a float valve 5; One water inlet is connected to the municipal pipe network 1 through a pipeline, and the water outlet pipe 92 arranged on the water outlet of the water tank 9 is connected to the other water inlet of the mixed flow tank 15 through the booster pump 6, and the mixed water outlet of the mixed flow tank 15 is connected to the water pump At the input end of the unit 18, a water distributor 8 is provided at the bottom of the inner cavity of the water tank 9, and the water distributor 8 includes an annular pipe 81, a straight pipe 82, and a connecting pipe 83 arranged crosswise on the same plane. 81. The intersections of the straight pipes 82 and the connecting pipes 83 communicate with each other to form a network-shaped water channel. The annular pipe 81 and the straight pipe 82 have a plurality of through holes evenly distributed, and the connecting pipe 83 is connected with the water outlet pipe 92 . The above-mentioned annular pipe 81, straight pipe 82, and connecting pipe 83 can be connected in various shapes, as long as the pipes can communicate with each other and the through holes on the pipes can be distributed to different parts of the water tank 9 as evenly as possible.

When the booster pump 6 is working, the water distributor 8 absorbs water from different positions at the bottom of the water tank 9 through the through holes distributed in different positions, so as to realize all-round water intake and make the water in the entire water tank flow, which can effectively avoid secondary water supply. pollute.
