Description
Technical field:
The present invention relates to high-lift water supply and drainage field, be specifically related to a kind of water pump start and stop water hammer effect cancellation element.
Background technology:
Along with development and new equipment, the application of new technique of economic technology, increasing big flow, high-lift plumbing set
The standby engineering fields such as building, municipal administration and water conservancy that are applied to, such is high-lift simultaneously, water present in distance water supply and sewage work
Hammer phenomenon the most increasingly comes into one's own.
The most high-lift, distance water supply and sewage work affect to alleviate water hammer, use water-hammer arrester more, but engineering is real
Trampling and show, install merely water-hammer arrester on water pump water outlet pipeline, effect is poor.When water pump suddenly open, all standing moment, water hammer is existing
As seriously, greatly affecting the service life of water supply and sewerage pipeline.
It addition, the most high-lift, distance water supply and sewage work slow open also by water pump, slow stop mode to prevent water hammer
Generation.Under normal circumstances, this kind of mode can effectively prevent water hammer, but such as fortuitous events such as burst power failures, water pump is rapid
After stopping, water hammer is inevitable, there is potential safety hazard.
In sum, the water hammer that the most high-lift, distance water supply and sewage work need a set of installation simple, reliable and stable disappears
Except device.
Summary of the invention:
Present invention aims to water hammer present in high-lift, distance water supply and sewage work, it is provided that a kind of structure
Simply, water pump start and stop water hammer effect cancellation element reasonable in design, easy to use, it can reduce even elimination water pump start and stop moment
The water hammer produced, it is ensured that system pipeline safe and reliable.
In order to solve the problem existing for background technology, the technical solution used in the present invention is: it includes that water pump water outlet is done
Manage, go out water conduit tube check-valves, maintenance gate valve one, bypass pipe, pressure release arm check-valves, relief valve, maintenance gate valve two, swelling water
Case；The B end of described water pump water outlet main is connected with water pump, and A end is connected with supply and drain water system outlet, and water pump water outlet main is installed
There is water conduit tube check-valves, go out water conduit tube check valve downstream and be connected to bypass pipe, bypass pipe is provided with maintenance gate valve one, bypass pipe
Middle part connects pressure release arm, pressure release arm is sequentially installed with pressure release arm check-valves and relief valve, the C end ground connection of pressure release arm
At leakage, catch pit or other drainage measure, bypass pipe is connected to overhaul gate valve two, bypass pipe end and swelling water after pressure release arm
Case connects.
Further, described bypass pipe is identical with the caliber of pressure release arm, and the caliber of water pump water outlet main is more than bypass pipe
Caliber.
After using said structure, present invention have the beneficial effect that on the one hand it can be pipeline moisturizing in water pump all standing moment,
Eliminating or reduce pipeline negative pressure, the process formed from water hammer goes to alleviate the effect of water hammer；On the other hand, after water hammer is formed, use
The mode that superpressure sluices, by Stress control below ultimate value, adequately protect pipeline, it addition, when water pump suddenly rise, all standing time, also
Expansion tank equalizing main pressure can be passed through, eliminate or reduce pump start water hammer effect.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention.
Description of reference numerals: water pump water outlet main 1, go out water conduit tube check-valves 2, maintenance gate valve 1, bypass pipe 4, pressure release are propped up
Pipe check-valves 5, relief valve 6, maintenance gate valve 27, expansion tank 8.
Detailed description of the invention:
Below in conjunction with the accompanying drawings, the present invention is further illustrated.
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and be embodied as
Mode, is further elaborated to the present invention.Should be appreciated that detailed description of the invention described herein is only in order to explain this
Invention, is not intended to limit the present invention.
As it is shown in figure 1, this detailed description of the invention adopts the following technical scheme that it includes water pump water outlet main 1, goes out water conduit tube
Check-valves 2, maintenance gate valve 1, bypass pipe 4, pressure release arm check-valves 5, relief valve 6, maintenance gate valve 27, expansion tank 8；Institute
The B end stating water pump water outlet main 1 is connected with water pump, and A end is connected with supply and drain water system outlet, and water pump water outlet main 1 is provided with
Go out water conduit tube check-valves 2, go out water conduit tube check-valves 2 downstream and be connected to bypass pipe 4, bypass pipe 4 is provided with maintenance gate valve 1, other
Connect pressure release arm in the middle part of siphunculus 4, pressure release arm is sequentially installed with pressure release arm check-valves 5 and relief valve 6, pressure release arm
At C termination floor drain, catch pit or other drainage measure, bypass pipe 4 is connected to overhaul gate valve 27, bypass pipe 4 end after pressure release arm
End is connected with expansion tank 8.
Further, described bypass pipe 4 is identical with the caliber of pressure release arm, and the caliber of water pump water outlet main 1 is more than bypass
The caliber of pipe 4.
Water pump rises moment suddenly, and a pressure part promotes current to flow along main pipe water pump water outlet main 1, and a part is for expanding
Water tank 8 moisturizing, along with the carrying out of expansion tank 8 moisturizing, the pressure of expansion tank 8 constantly increases, final and water pump water outlet pressure
Consistent holding is constant, therefore can eliminate or reduce pump start water hammer effect；After water pump all standing, owing to fluid inertia is only going out water conduit tube
Going back to valve 2 downstream and produce negative pressure, expansion tank 8 is water pump water outlet main 1 moisturizing by bypass pipe 4, prevents aqueous vapor from separating, and current are used to
Property terminate after, exist negative pressure backflow, produce water hammer effect possibility, water hammer effect acts predominantly on out water conduit tube check-valves 2 times
At trip, water hammer effect occurs herein, and active force is conducted to relief valve 6 and expansion tank 8 by bypass pipe 4, is on the one hand swollen
The moisturizing of swollen water tank 8, when on the one hand pressure is higher than pressure release value, relief valve 6 pressure release, reduces water hammer effect active force, eliminates or reduce
The water hammer effect impact on pipeline.
This detailed description of the invention can reduce even in terms of water hammer effect forming process and water hammer effect mechanism two
Eliminate water hammer effect, it is possible to effectively reduce the harm of water pump start and stop water hammer effect, safeguard the stability of supply and drain water system.
The above, only in order to technical scheme to be described and unrestricted, those of ordinary skill in the art are to this
Other amendment or equivalent that bright technical scheme is made, without departing from the spirit and scope of technical solution of the present invention,
All should contain in the middle of scope of the presently claimed invention.
