Abstract
The utility model provides a kind of antifouling separative valves, comprises Lift check valve, Bivalved check valve and bolt, and described Bivalved check valve is connected in the middle of two Lift check valves, and two Lift check valves are bolted and Bivalved check valve is fixed on centre.Owing to adopting technique scheme, two Lift check valves and a Bivalved check valve series connection, reach and cut off entering of sewage, ensure the effect of upstream water supply safe and sanitary, and when a safety check goes wrong, other two safety check are still working on, thus add the reliability of safety check, therefore non-return is effective, can not affect the safety of water supply line.
Description
Technical field
The utility model relates to valve field, particularly relates to a kind of antifouling separative valves.
Background technique
Current water supply network, for anti-backflow, pipeline is serially connected with safety check and prevents medium back flow, but carry out non-return, when safety check has problem to be not closed completely due to the single safety check adopted at present, non-return effect is bad, easy generation is leaked, and especially the backflow of Drinking Water pipeline is seriously polluted, and general check valve foot can not disposablely just be accomplished to close completely, cut off entering of sewage, upstream water supply safe and sanitary can not be ensured.And once seal break-off, its partition effect will be lost efficacy, the safety water supply of water-supplying unit and the safety of human lives's water were had a strong impact on.
Model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of antifouling separative valves, comprise Lift check valve, Bivalved check valve and bolt, described Bivalved check valve is connected in the middle of two Lift check valves, and two Lift check valves are bolted and Bivalved check valve is fixed on centre.
Described Lift check valve by the valve seat in valve body, the valve gap be arranged on valve body, valve body, the spool be arranged on valve gap, be arranged on spring on spool and sealing seat forms.
Described Bivalved check valve, by valve body and the valve shaft be arranged in valve body, is arranged on the torsion spring on valve shaft and two flaps compositions.
The beneficial effects of the utility model are: owing to adopting technique scheme, two Lift check valves and a Bivalved check valve series connection, reach and cut off entering of sewage, ensure the effect of upstream water supply safe and sanitary, and when a safety check goes wrong, other two safety check are still working on, thus add the reliability of safety check, therefore non-return is effective, can not affect the safety of water supply line.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
In figure, 1, Lift check valve; 2, Bivalved check valve; 3, bolt; 4, valve body; 5, valve gap; 6, spool; 7, valve seat; 8, sealing seat; 9, spring; 10, flap; 11, valve shaft; 12, torsion spring.
As shown in Figure 1, described Bivalved check valve 2 is connected in the middle of two Lift check valves 1, and two Lift check valves 1 are connected by bolt 3 and Bivalved check valve 2 is fixed on centre.
Described Lift check valve 1 by the valve seat 7 in valve body 4, the valve gap 5 be arranged on valve body 4, valve body 4, the spool 6 be arranged on valve gap 5, be arranged on spring 9 on spool 6 and sealing seat 8 forms.
Described Bivalved check valve 2, by valve body 4 and the valve shaft 11 that is arranged in valve body 4, is arranged on torsion spring 12 on valve shaft 11 and two flaps 10 form.
Two Lift check valves 1 and a Bivalved check valve 2 are connected, and have cut off entering of sewage, and when one of them goes wrong, other two are still working on, adding reliability.
Be described in detail of the present utility model by embodiment above, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
