Introduce each working state of multi-way valve respectively according to regeneration step below
State is made in the system water conservancy project: chamber opening (9) is positioned at 9 o ' clock positions under the spool, facing to valve body lower floor raw water inlet (13), at the bottom of former water flows under the multi-way valve chamber and enters the swap tank jar by valve body lower interface (18) again, the resin layer of upwards flowing through, flow into chamber on the spool by roof hatch through chamber round (6) on tank deck connection mouth (14) and the spool, last chamber opening is and 3 o ' clock positions that facing to water outlet (15), softened water is flowed out by water outlet (15).
The displacement of suction salt: spool is rotated counterclockwise 45 degree, and after chamber opening (9) was crossed raw water inlet (13) under the spool, facing to valve body regeneration drain opening (22), under shed (7) 12 o ' clock positions in chamber faced toward into regenerated liquid mouth (19) on the spool at 6 o ' clock positions.With the sensitive switch k3 spring sheet of controlling salt pump circuit contact circuit connection, salt pump startup with regeneration contact on the positioning disk W2 that the spool drive link is connected this moment.Regenerated liquid enters chamber on the spool by advancing regenerated liquid mouth (19) through chamber under shed (7) on the spool, enter swap tank by chamber round (6) on the spool and tank deck connection mouth (14) by tank deck, the resin layer of flowing through is downwards replaced, and discharges (can be set at 30-60 minute) by jar bottom opening chamber opening (9) under valve body lower interface (18) and spool by regeneration drain opening (22) again.
Just wash: spool is rotated counterclockwise 45 degree, chamber opening (9) is just being washed drain opening (16) at 3 o ' clock positions facing to valve body under the spool, after chamber under shed (7) is crossed into regenerated liquid mouth (19) on the spool, regeneration contact on the positioning disk W2 is left with the sensitive switch k3 spring sheet of controlling the salt pump circuit, circuit disconnects, salt pump stops, when chamber under shed (7) on the spool is aimed at when just washing water intake (10) at 9 o ' clock positions, the water inlet of former water enters tank deck by valve inleting water vertical passage (11) by just washing water intake (10) chamber round (6) and tank deck connection mouth (14) on spool, the resin layer of flowing through downwards cleans, and waste water flows under the spool chamber through valve body lower interface (18) at the bottom of by jar and discharges (can be set at 10-30 minute) by just washing drain opening (16) again.
Backwash: spool is rotated counterclockwise 45 degree, chamber opening (9) faces toward valve body backwash water intake (24) at 12 o ' clock positions under the spool, after chamber under shed (7) is crossed and is just washed water intake (10) on the spool, aim at backwash drain opening (20) at 6 o ' clock positions, former water water inlet enters spool through valve body backwash water inlet horizontal channel (12) by backwash water intake (24) chamber opening (9) under spool, at the bottom of entering the swap tank jar by valve body lower interface (18) again, the resin layer of upwards flowing through oppositely cleans, waste water enters chamber on the spool by tank deck chamber round (6) on tank deck connection mouth (14) and spool, flow out by backwash drain opening (20) again, discharge (can be set at 10-30 minute) through backwash draining vertical passage (21) and draining horizontal channel (23) by just washing drain opening (16) downwards, qualified until the chlorine root.
Change working state over to: spool continues to be rotated counterclockwise 45 degree, and facing to raw water inlet (13), chamber under shed (7) can produce water at 3 o ' clock positions facing to water outlet (15) to chamber opening (9) on the spool at 9 o ' clock positions under the spool.
Automatic control section
As shown in Figure 8, the design's multi-way valve can adopt servodrive mechanism, to make things convenient for manually-operable.Also operable automatically.
As shown in the figure, Z1 driven by motor positioning disk W1 (30) realizes the rotating speed of 180 minutes/circle, totally 90 pin holes on the positioning disk W1, each pin hole (29) is represented 2 minutes time, when going up contact pin (28), W1 contacts with the normally closed sensitive switch K2 spring sheet in positioning disk W2 top, when causing the connection of Z2 circuit, it is moving that the Z2 motor drives the spool rotation by spool drive link (1), is in coaxial positioning disk W2 with drive link and promptly turns.When next via positions is spent in rotation 45, stopping projection (26) on the positioning disk W2 is gone up this contact pin with positioning disk W1 and is pushed open, and itself and K2 sensitive switch spring sheet are left, and the Z2 circuit disconnects, spool and positioning disk W2 stop operating, and carry out the reproducer of this position.This moment, positioning disk W1 still was rotated further under the Z1 driven by motor, when next contact pin on it contacts with K2, Z2 connects once more, drive positioning disk W2 is rotated further 45 and spends next path, again this contact pin of positioning disk W1 is pushed open by another stopping projection that moves to this position then, positioning disk W2 is stopped operating once more, be parked in and carry out next reproducer on this path.Positioning disk W2 and spool stop time are exactly the used time of this program, and it is to be determined by the interval of the contact pin on positioning disk W1 hole count, and can change by the interval of adjusting contact pin and contact pin.So continue to finish whole regenerative process.
Positioning disk W2 go up to also have with spool on chamber under shed (7) be positioned at regeneration contact (27) on the same vertical line, when chamber under shed (7) on the spool forwards into the regenerated liquid mouth to, the regeneration contact contacts with the sensitive switch k3 spring sheet of control salt pump circuit, and circuit is connected and made the salt pump startup.When chamber under shed (7) on the spool when forwarding the next position to, the regeneration contact disconnects with the sensitive switch k3 spring sheet of control salt pump circuit, and salt pump stops.
When positioning disk W2 rotates a whole circle, when regeneration ending is got back to working state, W1 still continues rotation, regeneration ending projection (25) before positioning disk W1 is positioned at initial position is when rotating to initial position, the sensitive switch K1 that often opens that regeneration ending position projection will be controlled the Z1 circuit engages, the Z1 circuit is disconnected, and W1 stops operating, and reproducer stops.The contact pin of positioning disk W1 does not also engage with K2, and positioning disk W2 and spool just are parked in the system water conservancy project all the time and make state.
When the resin container water outlet was lost efficacy once more, manual equidirectional turn positioning disk W1 made the regeneration ending projection of positioning disk W1 leave initial position, but first contact pin can not surpass initial position, this moment, Z1 connected, and first contact pin combines with K1 after a while, begins the automatic regeneration program once more.As think to begin automatically reproducer, and available as above positioning disk W1 contact pin regularly promotes the regeneration ending projection with the principle that K2 regularly engages, and the break-make of control Z1 circuit gets final product.
