[0030] In order to realize linkage control of the two valves and satisfy the one-open-one-closed state, the two ends of the push-pull rod 13 of this embodiment are respectively hinged to one end of the two valves 100 away from the hinge seat 15, and the length of the push-pull rod 13 satisfies the one-open-one-closed state of the two valves 100. Figure 1 or Figure 2 As shown, it is preferably configured as follows: the push-pull rod and the valve plates of the two valves form a right-angled triangle structure.

[0047] Embodiment 6

[0048] This embodiment provides a water treatment system using a single-control on-off synchronous valve group of any of the above-mentioned embodiments. The water treatment system includes but is not limited to an initial rainwater filtration pool or a biological pretreatment pool or a chemical reaction pretreatment pool or a biological reaction pool. This embodiment takes the initial rainwater filtration pool 20 as an example for detailed description. The installation method of the synchronous valve group in other pools can refer to the installation of the filtration pool in this embodiment, and the details will not be repeated. Figure 1 to Figure 3 The first pipe 11 is provided at the drain port 201 or the filtered water outlet 202 at the bottom of the filter pool 20, the second pipe 12 is correspondingly provided at the filtered water outlet 202 or the drain port 201 at the bottom of the filter pool 20, the hinged seat 15 of the valve group is fixedly installed at the bottom of the filter pool 20, the control rod limiting guide groove 17 is fixedly installed at the bottom of the filter pool 20, and the hoist 16 is fixedly installed at the walkway board 203 of the filter pool 20. Generally, the filter pool 20 is also provided with an overflow port 204, a filtered water inlet pipe 205, a flushing water inlet pipe 206, and an ultrasonic level meter 207.

[0049] Combined with the working needs of the filter pool, the outlet valve and the drain valve used are required to adopt a one-on-one-off-the-other-off mode. The application principle and process of the single-control one-on-one-off-the-other-off synchronous valve group in the filter pool are as follows:

[0050] Filtration stage: At the beginning of filtration, the drain valve is in the closed state and the outlet valve is in the open state. The filtered water is introduced into the pool from outside the pool through the pipe and filtered through the fiber bundle filler. The filtered water is discharged from the pool through the outlet valve and the outlet pipe.

[0051] Flushing stage: When the ultrasonic level meter measures that the water level in the pool rises to the flushing water level or the fiber bundle filler needs to be flushed at a predetermined time, the flushing procedure is started. Flushing the filter pool will produce garbage and wastewater. At this time, it is necessary to close the outlet valve and open the drain valve at the same time. This patent considers that these two valves are controlled by an electric (manual) two-purpose hoist under the control of the PLC control box to form a valve group that opens and closes. In the flushing stage mode, first stop the water inlet to the filter pool. Under the control of the electric (manual) two-purpose hoist, the control rod moves upward. Under the joint action of the control rod, the force transmission rod and the push-pull rod, the drain valve is gradually opened and the outlet valve is synchronously gradually closed. When the electric (manual) two-purpose hoist runs to the set position, it automatically stops. At the same time as the electric (manual) two-purpose hoist automatically stops, flushing water is introduced to flush the fiber bundle filler. The pollutants filtered and intercepted by the fiber bundle filler are continuously flushed by the water flow, and the pollutants are discharged into the sewage pipe through the drain valve and the drain pipe with the water flow.

[0052] Preparation stage for the next filtration cycle: After the scheduled flushing time is completed, under the control of the PLC control box, the flushing water inlet facility is closed, and then the electric (manual) dual-purpose gate opener is started, and the control lever is controlled to move downward. Under the joint action of the control lever, force transmission rod and push-pull rod, the drain valve is gradually closed and the outlet valve is gradually opened, and the system prepares for the next filtration cycle.

[0053] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
