Description
Technical field
The present invention relates to a kind of water treatment control valve.
Background technology
At present, for ion-exchange water softener, general employing counter-current regeneration technique, there is province's water, economize salt, feature that effluent quality is good, it is subject to the favor of more and more user, but co-current regeneration technological operation control is simple, to coming water turbidity requirement low, also many application are maintained, so the water treatment control valve (i.e. soft water valve) on current domestic and international market is except co-current regeneration soft water valve, counter-current regeneration soft water valve, also have and a kind of namely can be used for the soft water valve that adverse current also can be used for co-current regeneration, be user-friendly to.
Chinese patent 200330100989.6 describes the soft water valve of a kind of applicable adverse current and co-current regeneration, Fig. 1 is the soft water multiway valve vertical view of this patent, as shown in Figure 1, except water-in, water outlet, water port, two are also had to inhale salt injector locations: adverse current injector locations 20 and downstream injection device position 21, corresponding adverse current inhales salt interface 22 and following current suction salt interface 23 respectively, as counter-current regeneration technique selected by soft water valve, then downstream injection device position 21 place injector is taken out and change stifled head into, and block following current and inhale salt interface 23, vice versa. This kind of design makes the design of the water route in control valve too complicated, and the dismounting of injector also bothers, and in-site installation debugging must professional just be gone, and two cover configuration simultaneously too increases unnecessary cost, causes waste.
Summary of the invention
It is an object of the invention to solve the defect that in prior art, water route design is too complicated, cost is too high, it is provided that the water treatment control valve that a kind of structure is more simple, cost is lower.
In order to realize above-mentioned purpose, the present invention by the following technical solutions:
A kind of water treatment control valve, its one first intake-outlet, one the 2nd intake-outlet, a sewage draining exit and salt solution providing unit of including a valve body and being connected with described valve body, described valve body tank softening with is connected, described softening tank includes an import and an outlet, its feature is, described water treatment control valve also includes a waterway switching device, a channel switching device, a first channel and a second passage;
One end of described first channel and described second passage is communicated in described valve body, and the other end is communicated in described import or described outlet respectively;
Described waterway switching device is arranged in described valve body, for the connection switched between described first channel, described second passage, described first intake-outlet, described 2nd intake-outlet, described sewage draining exit and described salt solution providing unit;
Described channel switching device is arranged between described first channel and described second passage and described import and described outlet, for switching being connected of described first channel and described second passage and described import and described outlet.
Herein, the switching normally carrying out and inhaling the operations such as salt regeneration of water treatment control valve general control water softening, also being applicable to counter-current regeneration owing to water treatment control valve involved in the present invention has both gone for co-current regeneration, the first intake-outlet and the 2nd intake-outlet all may be used for into water and water outlet. Hereinafter illustrate the function of waterway switching device and channel switching device:
In following current (namely, first intake-outlet water inlet, 2nd intake-outlet water outlet) when running, waterway switching device switches to the state that sewage draining exit is closed, the first intake-outlet is connected, the 2nd intake-outlet is connected with second passage with first channel, and channel switching device switches to the state that first channel is connected, second passage is connected with outlet with import. Former water from the first intake-outlet flow into softening tank carry out softening after, then flow out from the 2nd intake-outlet.
When salt regeneration is inhaled in following current, waterway switching device switches to the state that sewage draining exit is connected, salt solution providing unit is connected with first channel, the first intake-outlet is connected with the 2nd intake-outlet with second passage, identical when the setting of channel switching device runs with following current. Salt solution is discharged from sewage draining exit after regenerating from the softening tank of salt solution providing unit inflow.
In adverse current (namely, 2nd intake-outlet water inlet, first intake-outlet water outlet) when running, arranging when keeping running with following current of waterway switching device is identical, channel switching device switch to first channel with export be connected, state that second passage is connected with import. Former water from the 2nd intake-outlet flow into softening tank carry out softening after, then flow out from the first intake-outlet.
When adverse current inhales salt regeneration, arranging when keeping inhaling salt regeneration with following current of waterway switching device is identical, and the setting of channel switching device and adverse current are run identical. Salt solution is discharged from sewage draining exit after regenerating from the softening tank of salt solution providing unit inflow.
As mentioned above, the water treatment control valve that the present invention relates to only needs the import of first channel with second passage and softening tank switches channel switching device with being connected of outlet, then coordinates the waterway switching device in valve body can complete the conversion running and inhaling the operations such as salt.
