Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

Embodiment one:

As depicted in figs. 1 and 2, a kind of multichannel draining control valve, comprise valve body 1, valve body 1 is provided with a plurality of water intakes 2 and a water outlet 3, present embodiment is an example with three water intakes 2, each water intake 2 is communicated with an intake pipe 12, and water outlet 3 is communicated with a waste pipe 13, and the water unification in the multichannel intake pipe 12 is discharged by a waste pipe 13.

Valve body 1 is divided into epicoele 4 and cavity of resorption 5, the centre separates with dividing plate 6, three water intakes 2 are communicated with epicoele 4, a water outlet 3 is communicated with cavity of resorption 5, dividing plate 6 is provided with three current ports 7, three current ports 7 that the position is set is corresponding with three water intakes 2, one spool 8 is set in epicoele 4, spool 8 can be done in epicoele 4 and relatively rotate, the outer surface of the internal surface of epicoele 4 and spool 8 is sealed and matched, avoid flowing out the slit of water between spool 8 and epicoele 4 internal surfaces the mode that the internal surface of general epicoele 4 cooperates with the outer surface of spool 8 employing liquid sealing.

Three current ports 7 all are communicated with cavity of resorption 5, and cavity of resorption 5 pools together the water inlet on each road, and are unified by waste pipe 13 discharges.

Spool 8 is provided with three water channels 9, and as shown in Figure 1, water channel 9 will be positioned at three water intakes 2 on epicoele 4 tops and be connected with three current ports 7 on being positioned at dividing plate 6, form three relatively independent flow channels.At this moment, be equivalent to water control valve and open, the water in three intake pipes 12 flow in the cavity of resorption 5 by corresponding water intake 2, water channel 9 and current port 7 respectively, discharges via water outlet 3 and waste pipe 13 at last.

As shown in Figure 2, after spool 8 rotated 90 degree, three water intakes 2 that spool 8 will be positioned at epicoele 4 tops disconnected mutually with three current ports 7 that are positioned on the dividing plate 6.At this moment, be equivalent to water control valve and close, intake pipe 12 disconnects mutually with waste pipe 13, and the water in the pipeline does not circulate.

In the present embodiment, spool 8 can be manual spool, also can be the mortor operated valve core.

When spool 8 adopts manual spool, be provided with one handle 11 at an end of spool 8, can come rotational valve core 8 by rotatable handle 11.

When spool 8 was electronic spool, the rotation of spool 8 relied on solenoid controlled, and electromagnetic coil is connected with control unit in water supply equipment or the watering equipment by electric wire.

Embodiment two:

As shown in Figure 3 and Figure 4, a kind of multichannel draining control valve, comprise valve body 1, valve body 1 is provided with a plurality of water intakes 2 and a water outlet 3, present embodiment is an example with three water intakes 2, each water intake 2 is communicated with an intake pipe 12, and water outlet 3 is communicated with a waste pipe 13, and the water unification in the multichannel intake pipe 12 is discharged by a waste pipe 13.
