Abstract
An overlying bypass device of a pipeline network comprises a water inlet, a pump set, a bypass pipe, a check valve, a butterfly valve and the user pipeline network, and is characterized in that the water inlet (6) is respectively connected with the pump set (1) and the bypass pipe (5), the bypass pipe (5) is connected with the check valve (4), the check valve (4) is connected with the butterfly valve (3), the butterfly valve (3) is connected with the user pipeline network (2), and the pump set (8) is connected with the user pipeline network (2).
Description
Technical field
The utility model relates to about Automatic Water System technical field, specifically a kind of pipe network pressure-superposed by-pass collar.
Background technology
After the bypass of general pipe network Pressure-superposed water supply equipment comes into operation, there is no exit function, when flap valve fault, be not easy to maintenance.
Summary of the invention
That the purpose of this utility model is to provide a kind of easy access and possess the pipe network pressure-superposed by-pass collar that can come into operation and close exit function.
The purpose of this utility model is achieved in that
A kind of pipe network pressure-superposed by-pass collar, comprise water inlet, pump group, bypass pipe, flap valve, butterfly valve, user's pipe network, it is characterized in that: water inlet (6) connects respectively pump group (1) and bypass pipe (5), bypass pipe (5) connects flap valve (4), flap valve (4) connects butterfly valve (3), butterfly valve (3) connects user's pipe network (2), and pump group (8) connects user's pipe network (2).
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1 is pump group, 2 is user's pipe network, and 3 is butterfly valve, and 4 is flap valve, and 5 is bypass pipe, and 6 is water inlet.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As Fig. 1, in the time that intake pressure reaches user's ductwork pressure, pump group (1) quits work, and water directly flows to user's pipe network (2) from water inlet (6) through bypass pipe (5), flap valve (4), butterfly valve (3).
In the time that pump group (1) is worked, flap valve (4) cuts out, and water flows to user's pipe network (2) from water inlet (6) through pump group (1).
In the time that flap valve (4) breaks down, can exit bypass function by manual-lock butterfly valve (3), easy access by-pass collar, after flap valve (4) fault is got rid of, reopens butterfly valve (3) bypass function that can come into operation.
Claims (1)
1. a pipe network pressure-superposed by-pass collar, comprise water inlet, pump group, bypass pipe, flap valve, butterfly valve, user's pipe network, it is characterized in that: water inlet (6) connects respectively pump group (1) and bypass pipe (5), bypass pipe (5) connects flap valve (4), flap valve (4) connects butterfly valve (3), butterfly valve (3) connects user's pipe network (2), and pump group (1) connects user's pipe network (2).
