Abstract
The utility model relates to a technology of an energy eliminating device which can minimizing the influence of the water impacting effect. The water hammer eliminator comprises a pipe, an outer casing which is communicated with the pipe, an air exhausting valve which is connected with the outer casing and communicated with the outer casing, an air sac which is installed in the outer casing, an air inlet pipe and a valve which is connected with the air inlet pipe, and one end of the air inlet pipe is communicated with the air sac, and the other end is penetrated out of the outer casing. The device can store water at the peak value of the water hammer, which reduces the water impact, and at the valley value, the water hammer can supplement water to the pipelines, which overcomes the damage to facilities from the water hammer, and the water is not wasted.
Description
The utility model belongs to the technical field that is suitable for the influence of water hammer is reduced to the energy dissipator of minimum.
The water-hammer arrester that is used for Long-distance Pipeline for Water Conveyance now, general piston, lever and the weight of comprising, after the water pipe internal pressure surpassed certain value, outfall was opened in piston motion, the impact force of buffered water.But this water-hammer arrester can only be opened outfall, and water is outwards sprayed, though cushioned the impact force of water, outfall can not be closed automatically, wastes a large amount of water, and water hammer can not supplementing water when valley occurring.
The purpose of this utility model provide a kind of can water storage when peak value appears in water hammer in pipeline, the water-hammer arrester that elimination water hammer that can supplementing water when producing valley works the mischief to equipment.
This water-hammer arrester comprises pipe, and the shell with pipe is communicated with is connected on the vent valve that is communicated with shell on the shell, cased air bag, and the air inlet pipe that an end is communicated with air bag, the other end passes shell is connected on the valve on the air inlet pipe.
Because energy water storage in shell, when being in the water hammer peak value, the volume of compressing gasbag stores up into water, reduces the impact of water, and when being in the water hammer valley, air bag expands, and water is added in the pipeline go, and has both overcome the harm of water hammer to equipment, does not waste water again.
Accompanying drawing shows embodiment of the present utility model, wherein:
Figure 1 shows that the elevation of water-hammer arrester;
Figure 2 shows that the left view of water-hammer arrester;
Figure 3 shows that the right view of water-hammer arrester.
Water-hammer arrester as shown in the figure comprises pipe (1), with the garden cylindrical outer cover (2) that is communicated with of pipe (1), and the stack (6) that is communicated with shell (2) at the left end of shell (2).Be serially connected in the air valve (7) on the stack (6), be connected on vent valve (8) and pressure meter (9) on the stack (6), be contained in the air bag (13) in the shell (2), the air inlet pipe (12) of one end is communicated with air bag (13), the other end passes shell (2) right-hand member, be serially connected in the valve (10) on the air inlet pipe (12), be connected on the pressure meter (11) on the air inlet pipe (12).Shell (2) comprises tubular shell (3), is welded on the flange (5) of housing (3) right-hand member, is fixed by bolts to the stifled dish (4) on the flange (5).
Claims (2)
1, a kind of water-hammer arrester, comprise pipe (1), the shell (2) that is communicated with pipe (1), it is characterized in that on shell (2), being connected to the vent valve (8) that is communicated with shell (2), be contained in the air bag (13) in the shell (2), one end and the air inlet pipe (12) that air bag (13) is communicated with, the other end passes shell (2) are connected on the valve (10) on the air inlet pipe (12).
2, water-hammer arrester according to claim 1 is characterized in that shell (2) comprises tubular shell (3), is welded on the flange (5) of housing (3) right-hand member, is fixed by bolts to the stifled dish (4) on the flange (5).
