Abstract
The invention discloses a single-piston reverse flow control valve. The single-piston reverse flow control valve comprises a valve body. A cover plate is arranged at one end opening of the valve body. A water inlet channel is formed in the other end opening of the valve body. A cylindrical inner cavity is formed by the cover plate and the valve body. A piston is arranged inside the inner cavity. The piston is of a tubular structure. An annular groove is formed in the center of the side wall of the piston. A sealing gasket is arranged between the piston and the side wall of the valve body. The piston is matched with the sealing gasket. The side wall of the valve body is further provided with a central flow channel, a side flow channel, a water outlet flow channel and a sewage discharge flow channel, wherein the central flow channel and the side flow channel are both communicated with an external disposable groove. In the regeneration displacement process, a reverse-flow channel is formed among the piston, the annular groove in the piston, the valve body and the sealing gasket, the amount of consumed salt is reduced, and the cost is reduced.

The flow path wall of described center flow channels is provided with inhales salt runner, and the flow path wall of described outlet passage is provided with and filters runner, described suction salt runner and filter runner and be communicated with by external pipe, described suction salt runner and filter in runner the gate valve being equipped with and controlling to circulate.
The to-and-fro motion in the lumen of described piston, when normal product water, described suction salt runner and the gate valve filtered in runner are closed, described piston, body wall and sealing gasket coordinate the port blocking blowdown runner, described annular groove coordinates formation runner with body wall, described flow passage center flow channels and outlet passage.
When regenerating displacement, described outlet passage is closed, described suction salt runner is open-minded with the gate valve filtered in runner, described piston, body wall and sealing gasket coordinate the port blocking center flow channels, described annular groove coordinates formation runner with body wall, described flow passage side runner and blowdown runner.
Described sealing gasket comprises the first sealing gasket, the second sealing gasket, the 3rd sealing gasket, the 4th sealing gasket, the 5th sealing gasket, the 6th sealing gasket, the 7th sealing gasket and the 8th sealing gasket.
Described cover plate is provided with through hole, and described through hole mates with the piston rod of piston.
The single piston countercurrent control valve of above-described one is moved back and forth in body cavity by piston, makes the annular groove in piston, piston, forms different runners between body wall and sealing gasket.
Beneficial effect: the present invention, when regenerating displacement, by the annular groove in piston, piston, forms adverse current runner, reduces the consumption to salt, provide cost savings between body wall and sealing gasket.
