The tap water chamber 13 and the purified water chamber 14 formed by the purifying filter element 4 are both in a water storage chamber essentially, form the two-way complementation of the internal pressure and the external pressure, and also can install a pressure sensor therein to sense the pressure therein, when the pressure rise is larger, the purifying filter element 4 is seriously blocked, especially the inner side is blocked, at the moment, only one end of the tap water is needed to be opened and used independently, the scale on the inner side of the purifying filter element is washed away, thereby being not like the traditional water purifier, one side of the purifying filter element is always blocked by the scale due to the unidirectional movement of water, and the filter element needs to be replaced frequently. And if need change the filter core, only need open bolt 18, pull down head 1 and then take out purification filter core 4 can, then change the purification filter core of new, can normally use after installing head 1 through bolt 18.

The equipment can be directly connected with a tap water pipe in series, the required pressure is superposed on the basis of the pressure of a primary water supply pipe network of a water plant, the difference is large, the quantity is supplemented, the pressure of the pipe network can be fully utilized, the equipment does not need to be operated even in a water low peak period, compared with the traditional water supply equipment, the energy is saved by 30% -90%, the superposition of the pressure of the pipe network and an automatic frequency conversion operation mode are utilized, and the energy-saving effect is remarkably improved.

The centrifugal pump has the following three using states:

1. purified water was used alone: at this time, the first water outlet flange 6, i.e., the tap water outlet flange, is closed, the high-frequency high pressure generated by the pump body 3 flows the raw water to the periphery, and the raw water rapidly permeates into the purified water chamber 14 through the filter element, so that the scale and the like are suspended at the inner side of the purification filter element 4. Purified water after purification flows out from the second water outlet flange 10 connected with the purification chamber 14 after passing through the purification chamber, and is directly used by users.

2. Tap water was used alone: the second goes out water flange 10 and purifies water and goes out the water flange and close promptly this moment, the former rivers of high frequency high pressure that the high-speed rotation of the pump body 3 produced, rivers flow from 3 upper portions of the pump body, rivers flow from top to bottom in running water cavity 13 under the blockking of sealed water conservancy diversion lid 2, thereby will purify the effect that reaches indirect purification filter core such as the incrustation scale of filter core 4 inboard washed away in the lump, the running water directly flows from first play water flange 6 through running water cavity 13, reach the effect that need not often to change the filter core, and through the installation pressure sensors, if pressure data increase, the accessible is opened the purpose of running water flange alone and is washed.

3. Tap water and purified water were used simultaneously: at this moment, the first water outlet flange 6 and the second water outlet flange 10 are opened simultaneously for use, high-pressure water flow flowing out of the top of the pump body 3 is divided into two parts, one part directly flows away from the first water outlet flange 6, the other part flows out of the second water outlet flange 10 after entering the purification cavity 14 through the purification filter element 4, the sizes of water flows at two ends can be controlled by controlling valves in pipelines at the rear ends of the two water outlet flanges at any time, and under the condition that the inflow is not changed, the flow of tap water is reduced, the flow of purified water is increased, and vice versa.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
