Abstract
The invention discloses a water hammer eliminator, comprising a main pipe. The pipe wall of the main pipe is provided with a cylinder mechanism which is communicated with the inner part of a connecting pipe and is used for buffering the pulsating pressure of fluid; the cylinder mechanism comprises a cylinder body pipe with one end of being connected with the pipe wall of the main pipe in a sealingmanner; the cylinder body pipe is internally provided with a piston part; and the other end head of the cylinder body pipe is provided with a plug which leads the end head surface and one end surfaceof the piston part to form a normal-pressure closed space. The pulsating pressure of fluid can be relieved by the effect of air pressure, further a water pipe is protected and the service life of thewater pipe is prolonged.
Description
Technical field
The present invention relates to pipe fitting and make the field, especially a kind of the alleviation in the pipeline because of pressure pulse changes the water attack that produces or the water-hammer arrester of water hammer.
Background technique
In water system and fluid flow testing apparatus, often changing fluid path in the pipeline, hydrodynamic pressure and fluid flow is very frequent thing.Because the incompressibility of liquid, liquid in the pipeline can expand as an entity solid cylinder, produce water attack or water hammer, especially more outstanding when cutting off rapidly or reconciling current, this phenomenon can cause problems such as valve part is pulled, pipeline distortion, instrument damage, serious then can make pipe breakage, causes whole draining water supply system paralysis.
Original technician eliminates the method for water hammer, is after the water pipe internal pressure surpasses certain value, and drain opening is opened, and a part of water is flowed out, but also wasted great lot of water resources when alleviating water flow impact pressure.In the prior art, the water-hammer arrester that adopts air bag or elastic rubber tube structure is also arranged, this water-hammer arrester is to utilize the contraction or expansion of air bag and elastic rubber tube to eliminate the impact that current bring, though also solve water hammer, but under bigger water impact, the inefficacy thereby air bag and elastic rubber tube very easily break, working life is shorter.
Summary of the invention
Problem to be solved by this invention is exactly the defective at prior art, and a kind of water-hammer arrester of simple in structure, long service life is provided, and effectively alleviates or eliminates the impact that water attack, water hammer bring, reasonable in design, reliable operation.
In order to solve the problems of the technologies described above, the present invention adopts following technological scheme: a kind of water-hammer arrester is characterized in that: comprise the person in charge, be provided with on the tube wall of being responsible for and be responsible for the cylinder mechanism that inside communicates and is used for the buffer fluid pulsating pressure.
Further, described cylinder mechanism comprises the cylinder body pipe that an end and the person in charge's tube wall is tightly connected, and in the cylinder body pipe piston piece is set, and plug is set in another termination of cylinder body pipe makes formation one normal pressure confined space between this termination face and piston piece one end face.Behind a fluid impact, compressed gas can push back to original position with piston piece in this normal pressure confined space.
Preferably, the cylinder body pipe end is socketed with connecting head, and connecting head is provided with silk screw thread outside the bellmouth, and the person in charge's tube wall is provided with the joint to outer lug, and joint is provided with the bellmouth internal thread screw thread with the outer silk of bellmouth screw-thread fit, and the cylinder body pipe spins by screw thread with the person in charge.
Preferably, the cylinder body pipe end is connected by flange plate with the person in charge's tube wall, and the joint is provided with sealing gasket.
Preferably, be embedded with seal ring on the periphery of piston piece, increase sealability, improve cushioning effect.
Preferably, the described person in charge's two ends is provided with worm structure and is used to connect water pipe.
Advantage of the present invention: reasonable in design of the present invention, reliable operation; Invention is set on water pipe; when bigger pulsating pressure is arranged in the pipeline; cylinder mechanism moves to the pressed gas direction under hydraulic action; thereby provide good buffering; the impact that effective alleviation or elimination water attack and water hammer bring the water pipe tube wall; and then the protection water pipe, prolonged water pipe working life.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing:
Fig. 1 is the cylinder mechanism and person in charge's linkage structure schematic representation of the embodiment of the invention one;
Fig. 2 is the structural representation of cylinder mechanism of the present invention;
Fig. 3 is the cylinder mechanism and person in charge's linkage structure schematic representation of the embodiment of the invention two.
Embodiment
Embodiment one
In conjunction with Fig. 1, shown in Figure 2, a kind of water-hammer arrester, comprise and be responsible for 1, be responsible for 1 two ends and be provided with worm structure 10 and be used to connect water pipe, be provided with on 1 the tube wall and be responsible for the cylinder mechanism that 1 inside is common to the buffer fluid pulsating pressure mutually being responsible for, this cylinder mechanism comprises the cylinder body pipe 2 that an end and the tube wall of being responsible for 1 are tightly connected, piston piece 21 is set in the cylinder body pipe 2, be embedded with seal ring 22 on the periphery of piston piece 21, increase sealability, improve cushioning effect; Be provided with in another termination of cylinder body pipe 2 and form a normal pressure confined space 4 between the end face that plug 23 makes this termination face and piston piece 21.Cylinder body pipe 2 termination point casings are connected to connecting head 3, the outer silk of bellmouth screw thread 31 on the connecting head 3, be responsible for 1 tube wall and be provided with joint 11 to outer lug, joint 11 is provided with the bellmouth internal thread screw thread 12 that cooperates with the outer silk of bellmouth screw thread 31, and cylinder body pipe 2 and the person in charge 1 spin by screw thread.
Embodiment two
As shown in Figure 3, among the embodiment two, it is identical with embodiment one to be responsible for 1 structure and cylinder mechanism, different is, in embodiment two, cylinder body pipe 2 is to be connected by the flange plate 5 that cooperatively interacts with being responsible for 1, is provided with sealing gasket 51 in the joint of two flange plate 5 and improves sealability.
The present invention is installed in the water supply and sewerage system, when bigger fluid pulse pressure is arranged in the water pipe, thereby this fluid pulse pressure can promote piston piece 21 reduces volume from normal pressure confined space 4 to the motion of plug 23 directions, and the air pressure in the normal pressure confined space 4 is with the reducing and increase and react on piston piece 21 of spatial volume, thereby makes fluid pulse pressure obtain good buffering even elimination; After not had fluid pulse pressure, the pressurized gas in the normal pressure confined space 4 oppositely promotes piston piece 21 to original position, waits for water attack next time.
The foregoing description only is a preferred structure of the present invention, but structure characteristic of the present invention is not limited thereto, any those skilled in the art under the present invention in the field, the variation of being done or modify and all contain case in protection scope of the present invention.
