Background technique
At present in industry and family's softened water processing system, generally be divided into work and regeneration, working state is that water is produced to softened water after by treatment media, regeneration is to lack active treatment media filling salt solution, make treatment media again reply activity, for can switch operating and reproduced state, just need a control valve.
The general employing of control valve regeneration following current on market now, following current is exactly that displacement liquid starts displacement downwards from the treatment media top, namely from the side runner of valve body, enters, and discharges from center flow channels, and following current is larger to the consumption of salt, and operating cost is higher.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of valve body with adverse current runner, to the consumption of salt, provides cost savings while having reduced regeneration.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of valve body with adverse current runner, comprise valve body, a port of described valve body is provided with cover plate, another port is water inlet flow channel, described cover plate and valve body form a cylindrical cavity, in described inner chamber, be provided with piston, described piston is tubular structure, described piston side wall center is provided with annular groove, between described piston and body wall, also be provided with sealing gasket, described piston and sealing gasket coupling, on described body wall, also be provided with center flow channels, side runner, outlet passage, filter runner, inhale salt runner and blowdown runner, described suction salt runner and filtration runner are communicated with by external pipe, in described suction salt runner and filtration runner, be equipped with the gate valve of controlling circulation.
The to-and-fro motion in inner chamber 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 of blocking the blowdown runner, described annular groove coordinates runner of formation with body wall, described runner is communicated with center flow channels and outlet passage.
When the regeneration displacement, described outlet passage is closed, described suction salt runner and the gate valve filtered in runner are open-minded, described piston, body wall and sealing gasket coordinate runner of formation, described runner is communicated with center flow channels and inhales the salt runner, described annular groove coordinates another runner of formation with body wall, described runner is communicated with 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 and the 6th sealing gasket.
Described cover plate is provided with through hole, the piston rod coupling of described through hole and piston.
Above-described a kind of valve body with adverse current runner moves back and forth in body cavity by piston, makes between annular groove, body wall and the sealing gasket in piston, piston to form different runners.
Beneficial effect: the utility model, when the regeneration displacement, by between the annular groove in piston, piston, body wall and sealing gasket, forming the adverse current runner, has reduced the consumption to salt, provides cost savings.
