Description
Technical field
This utility model relates to a kind of backwash and controls valve
Background technology
Coagulation+filtration is a kind of common sewage disposal advanced treatment process, and filter tank is after using the regular period, filtering layer will be carried out periodic back flush。Discharge the impurity in filtering layer, foul with water first, filtering layer is played cleaning action；Second the resistance of Water treatment filtration operation is reduced。When adopting conventional rapid filter or V-type filter tank, after filtration, outlet pipe and backwash water inlet pipe are two systems separated, such sewage treating tube line length, and water damages big, operation maintenance complexity。
Utility model content
This utility model is for solving the problems referred to above, it is provided that a kind of backwash controls valve and the outlet pipe after filtration and backwash water inlet pipe connected, and shares a pipeline。
In order to achieve the above object, the technical scheme that this utility model adopts is as follows:
A kind of backwash controls valve, including valve body, it is characterized in that described valve body both sides are equipped with and filter out the mouth of a river, bottom is provided with backwash water inlet, it is provided with cover plate in valve body and covers bottom backwash water inlet, described cover plate is while being fixed on body base by bolted splice, and fixed position filters out mouth of a river homonymy with one of them；Described filter out the mouth of a river and backwash water inlet is respectively arranged with flange-interface。
Preferably, described cover plate and valve body joint adopt the encapsulant of water-swellable to fill。
Preferably, described cover plate adopts resistant material to make。
This utility model has the advantages that
1, without manual operation, easy to use, there is energy saving。
2, two-tube change single tube, simplifies structure。
3, frame for movement is simple, and operation maintenance is convenient, cheap。
Accompanying drawing explanation
Fig. 1 is the filter process schematic diagram that a kind of backwash described in the utility model controls valve；
Fig. 2 is the backwash process schematic diagram that a kind of backwash described in the utility model controls valve。
Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
As shown in Figure 1, a kind of backwash controls valve, including valve body 1, described valve body 1 both sides are equipped with and filter out the mouth of a river 2, bottom is provided with backwash water inlet 3, being provided with cover plate 4 in valve body 1 and cover bottom backwash water inlet, described cover plate 4 is hingedly fixed in bottom valve body 1 by bolt 5, and fixed position filters out the mouth of a river 2 homonymy with one of them；Described filter out the mouth of a river and backwash water inlet is respectively arranged with flange-interface 6。
Described cover plate 4 and valve body 1 joint adopt the encapsulant of water-swellable to fill。
Described cover plate 4 adopts resistant material to make。
When filter tank normal filtration, the cover plate 4 in this valve is final in horizontal positioned owing to the effect of self gravitation rotates down, and filter tank water outlet flows into next structures。
As in figure 2 it is shown, when needs carry out backwash, system controls filter tank and stops water inlet, start backwash pump。Backwash water inlet enters valve body 1 through backwash water inlet 3 with bigger flow velocity, and cover plate 4 is formed big impulsive force, pushes cover plate 4 open, and encapsulant water-swellable makes cover plate 4 and valve body 1 seal tightly simultaneously, and therefore completely enclosed one end filters out the mouth of a river 2。Backwash water inlet enters filter tank by valve body along opposite side filter tank outlet 2 and carries out backwash。
The present embodiment has the advantage that
1., without manual operation, hoisting capacity is from pipeline pressure。
2., together with the outlet pipe after filtration is effectively combined by this device with backwash water inlet pipe, pipeline has amphicheirality, both can go out clear water, can carry out again backwash, can be dual-purpose。
3. this apparatus structure is simple, can automatically carry out filtering with two processes of backwash, by setting electronic liquid level gauge, can send signal to switch board, then start backwash pump。
For a person skilled in the art, can technical scheme as described above and design, make other various corresponding changes and deformation, and all these change and deformation all should belong within this utility model scope of the claims。
Claims (3)
1. a backwash controls valve, including valve body, it is characterized in that described valve body both sides are equipped with and filter out the mouth of a river, bottom is provided with backwash water inlet, it is provided with cover plate in valve body and covers bottom backwash water inlet, described cover plate is while being fixed on body base by bolted splice, and fixed position filters out mouth of a river homonymy with one of them；Described filter out the mouth of a river and backwash water inlet is respectively arranged with flange-interface。
2. a kind of backwash according to claim 1 controls valve, it is characterised in that described cover plate and valve body joint adopt the encapsulant of water-swellable to fill。
3. a kind of backwash according to claim 1 controls valve, it is characterised in that described cover plate adopts resistant material to make。
