The utility model discloses well backflow preventer mounting structure is simple, fixed effectual, and dismantles the convenience, be convenient for maintenance and maintenance.
Description
Technical field
The utility model relates to water-treatment technology field, particularly relates to a kind of backflow preventer mounting structure.
Background technology
Backflow preventer (backflowpreventer) is the device that a kind of prevented feedwater piping current adopting retaining element to form flow backwards.
Backflow preventer is according to tap water supply equipment, especially the backflow of Drinking Water pipeline is seriously polluted, again without when effectively preventing backflow pollution device, in a kind of considered critical pipeline of development, water can only the waterpower control combination device of one-way flow, its function is under any operating mode, prevent ducted medium from flowing backwards, and avoids to reach the object polluted that flows backwards.Current backflow preventer is mainly divided into low resistance force counter flow stop and pressure reduction type backflow preventer two class, is less than 3 meters by the head loss of national standard low resistance force counter flow stop, and the head loss of pressure reduction type backflow preventer is less than 7 meters.
For backflow preventer, the utility model provides a kind of backflow preventer mounting structure.
Utility model content
Technical problem to be solved in the utility model is, for above-mentioned deficiency of the prior art, to provide a kind of backflow preventer mounting structure exactly.
The utility model solves the technical scheme that its technical problem adopts:
A kind of backflow preventer mounting structure, described mounting structure comprises backflow preventer, is connected to the first water service pipe of backflow preventer both sides and the second water service pipe, described first water service pipe is provided with the first stop valve, second water service pipe is provided with the second stop valve, be provided with strainer between first stop valve and backflow preventer, between the second stop valve and backflow preventer, be provided with movable joint.
As further improvement of the utility model, described first water service pipe and the second water service pipe both sides are also respectively equipped with the hook for supporting described first water service pipe and the second water service pipe.
As further improvement of the utility model, described hook comprises hard-wired fixed part and is located at the support portion of fixed part end, and described support portion is set to the semicircle with the first water service pipe and the second water service pipe form fit.
As further improvement of the utility model, described backflow preventer bottom is provided with gutter.
As further improvement of the utility model, be fixed with below described backflow preventer for fixing bracket.
The beneficial effects of the utility model are, simple, the good fixing effect of backflow preventer mounting structure in the utility model, and convenient disassembly, be convenient to maintenance process simulation.
