Technical field
The present invention relates to a kind of automatic cleaning system for condenser, specifically a kind of automatic cleaning system for condenser four-way change-over valve.
Background technology
At present, widely using of industry water air-cooled condenser and water-cooled central air-conditioning, bring comfortable, portable to the environment of people, but the energy-conservation and maintenance of the said equipment does not more thoroughly solve all the time, uses 200 hours continuously, begins to be settled out incrustation scale, dirt, biomembrane, precipitate in condensing tube simultaneously, and constantly thicken, hardening, rate of heat exchange declines rapidly, largely effects on refrigerating capacity, and power consumption is anxious simultaneously increases.Currently mainly there is following several settling mode:
1, manual cleaning, namely takes off heat exchanger end box and cleans each inside pipe wall of condensation；
2, Chemical cleaning, fills heat exchanger by cleanout fluid, discharges after snaking；
3, inject condensing tube with special balls and bring dirt.
Although above-mentioned 1,2 methods are reluctantly up to purpose, but environmental pollution is serious, can produce a large amount of chemical sewage, and downtime is long, and cost is high, and best life cycle is very short, does not otherwise reach the result of use of high efficient heat exchanging state.
Application number be 200820124626.3 patent of invention disclose a kind of automatic cleaning system for condenser, it is constantly changed the direction of a stream of water and cleaning brush washing motion in condensing tube by step motor drive flow converter, guarantee the effective cleaning in heat exchanger condenser tube, reaching the central air-conditioning moment is in high efficient heat exchanging state, reaches the effect of efficient energy-saving and emission-reducing.Flow converter in above-mentioned patent adopts motor and worm-gear speed reducer to forward different operating positions to moving axis and roll tube, thus reaching to change the effect of flow direction, its flow converter structure is complicated, and easily break down, simultaneously when roll tube rotates, block as gone to the local time water inlet not having hole, water impact phenomenon can be produced.
Summary of the invention
The technical problem to be solved is to provide a kind of automatic cleaning system for condenser four-way change-over valve for above-mentioned prior art; its simple in construction; easy to operate; can effectively control the water (flow) direction of automatic cleaning system for condenser; make unit on-line operation in non-stop-machine situation; reliability is high, does not have water impact phenomenon.
This invention address that the technical scheme that the problems referred to above adopt is: a kind of automatic cleaning system for condenser four-way change-over valve, it includes valve body and end cap, the first water-supply-pipe and the second water-supply-pipe it is provided with on the upside of described valve body, the 3rd water-supply-pipe and the 4th water-supply-pipe it is provided with on the downside of described valve body, it is coated with rotating shaft between described valve body and end cap, described rotating shaft is provided with transposition pipe, before and after described transposition pipe, both sides are provided with the first sealing strip, described valve body and rubbing surface of end cover middle part are provided with the second sealing strip, and described first sealing strip and the second sealing strip match.
Described rotating shaft one end is stretched out outside end cap, is provided with sealing device between described rotating shaft outer end and end cap lateral surface.
Compared with prior art, it is an advantage of the current invention that:
One automatic cleaning system for condenser four-way change-over valve of the present invention, its simple in construction, easy to operate; can effectively control the water (flow) direction of automatic cleaning system for condenser; making unit on-line operation in non-stop-machine situation, reliability is high, does not have water impact phenomenon.
