Water-purifying machine multichannel control device
Technical field
The utility model relates to a kind of control device that is used for water-purifying machine, particularly a kind of water-purifying machine multichannel control device.
Background technology
At present, the multi-way control valve system that uses on the water purifier market adopts imported product or foreign capital affiliate's product mostly, though its use properties is better, but it is on the high side, and block construction is very complicated, the maintenance cost height, and intellecture property and core technology are all grasped by offshore company.Though, the water-purifying machine multiway valve system that existing in recent years domestic manufacturer produces exploitation voluntarily or copys, the reliability of quality and the stability of use properties are also barely satisfactory, and the risk that also has the dispute of generation intellecture property that has.
Summary of the invention
The purpose of this utility model provides the pipe controller on a kind of water-purifying machine.
The purpose of this utility model is achieved through the following technical solutions:
A kind of water-purifying machine multichannel control device, its inside is provided with a pilot piping assembly, it comprises a base, an electric three passes ball valve and an electronic straight-through valve, this electric T-shaped valve be connected with that water inlet pipe, water outlet are taken over, water inlet is taken over, on taking over, water outlet is connected with rising pipe, the other end that this water outlet is taken over is connected in the outlet of this base, on taking over, water inlet is connected with blowdown connection, the other end that this water inlet is taken over is connected on the inlet of this base, and this electronic straight-through valve is located in this blowdown connection.
This water-purifying machine multichannel control device also comprises a loam cake and a lower cover, is formed with a space that is used to hold this pilot piping assembly after their combinations.
Wherein, also be provided with control circuit board and operating panel last covering.
Positive progressive effect of the present utility model is:
Control the passage of current by the open and close of magnetic valve, thereby can control the normal service state and the recoil state of water-purifying machine;
Because the physical dimension of the utility model product is small and exquisite, particularly highly lower, can finely satisfy the requirement of the compact outline that the small size machine pursued;
In addition, the production of this design, maintenance and maintenance are all very convenient and simple, are fit to very much family and use, and be stable and reliable for performance;
The control of use circuit control panel has good function expansibility.

Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1, a kind of water-purifying machine multichannel control device comprises a loam cake 1 and a lower cover 2, is formed with a space after their combinations, and a pilot piping assembly 3 is located in this space.
This pilot piping assembly 3 comprises a base 31, an electric three passes ball valve 32 and an electronic straight-through valve 33, this electric T-shaped valve 32 be connected with that water inlet pipe 34, water outlet take over 35, water inlet takes over 36, in water outlet adapter 35, be connected with rising pipe 37, the other end of this water outlet adapter 35 is connected in the outlet of this base 31, in water inlet adapter 36, be connected with blowdown connection 38, the other end of this water inlet adapter 36 is connected on the inlet of this base 31, and this electronic straight-through valve 33 is located in this blowdown connection 38.Base 31 links to each other with the hay tank (not shown) of water-purifying machine.
When works better service state (promptly making water state), drive electric three passes ball valve 32 and make water inlet pipe 34 and water inlet take over 36 connections, take over 35 and close water outlet, close electronic straight-through valve.At this moment, take over 36 from water inlet pipe 34 by T-valve and water inlet, enter in the hay tank that links to each other with base 31 without the former water that purifies, water bed of material after filtration from top to bottom in jar, be filtered and purify, take over 35 from water outlet then and flow out, by using for the user behind the rising pipe 37.
Through use after a while, a large amount of pollutents and impurity have been held back, adhered to and adsorbed to filtrate in the hay tank, this not only can have influence on the water supply capacity of equipment, even the equipment that also may have influence on produces the quality of water, therefore must clean filtrate, and the most effective filtrate cleaning way is the back flushing by current.Back flushing can make filter material layer loosening, and mutual friction and the collision of generation filtering material particle, by the current of reversed flow (from the bottom up) filtrate is held back, adhered to adsorbed contaminants and impurity and wash away then, thereby recover filtration, absorption and the reactive behavior of filtrate, thereby the water supply flow of restorer and product water water quality.
When needs recoiled, the connected state of electric three passes ball valve 32 can develop transformation, made water inlet pipe 34 and water outlet take over 35 and was communicated with and closes into water adapter 36, opened electronic straight-through valve 33 simultaneously.Under this state, the water inlet of equipment arrives water outlet by water inlet pipe 35, electric three passes ball valve 32 and takes over 35, and oppositely enter in the tank body of hay tank, this moment, jar intravital water (flow) direction was for from the bottom up, under certain flow and pressure condition, can make the loosening expansion of filter material layer, and can produce mutual friction of filtering material particle and collision, and become flexible, drop and pollutent and impurity that grazing is got off, can be reversed current and take away, and these current will be by the electronic straight-through valve 32 opened through blowdown connection 38 as sewage discharge to the sewage network system.
In addition, on loam cake 1, also be provided with control circuit board (not shown) and operating panel 11.This control circuit board is provided with pilot circuit, and it can be the existing pilot circuit that any one can be controlled above-mentioned motorized valve, also is provided with the auxiliary circuit that is used for relevant information is presented at operating panel 11, and it also can be a prior art.
