Abstract
The utility model mainly relates to a water pipe, in particular to a device for eliminating the water hammer phenomena produced in a water supply system and a fluid flow quantity testing device. The utility model relates to a water hammer eliminating device, which comprises a pipe body (1) and two flanges (5) arranged at the both ends of the pipe body. The utility model is characterized in that the inner hole of the pipe body (1) is provided with a flexible inner pipe (2), and the flexible inner pipe (2) is fixedly connected on the flanges (5). The utility model has the advantages that the water hammer phenomena can be effectively eliminated, and the water supply system and the fluid flow quantity testing device are better and simply protected.
Description
Technical field:
The utility model relates generally to a kind of water pipe, relates in particular to a kind of device that produces water hammer or water hammer in water system and the fluid flow testing apparatus of eliminating.
Background technique:
In water system and fluid flow testing apparatus; often changing system fluid path, fluid flow and hydrodynamic pressure etc. is very frequent thing; because the incompressibility of liquid is easy to produce water hammer or water hammer; especially when regulating rapidly and cutting off current; this phenomenon is more outstanding, usually can cause that accidents such as valve member is pulled, pipeline distortion, instrument damage take place.On water flow standard apparatus, work, occur as faults such as the leakage of meter-clamping apparatus sealing gasket, connecting tube axis sideslip, tested flow instrument damage capital in various degree.Particularly the master of water-supply systems, by-pass line be embedded in underground because the existence of water hammer or water hammer, often the pressure break valve member, damage pad, pull weld bond etc., then cause the water system seepage, cause road to subside, building sinks.
Summary of the invention:
The purpose of this utility model is to avoid the deficiencies in the prior art part and device that a kind of effective elimination water hammer or water hammer are provided.
The purpose of this utility model can be by realizing by the following technical solutions: a kind of water-hammer arrester, include body (1), two ends are provided with flange plate (5), and its main feature is that the endoporus of body (1) is provided with flexible interior pipe (2), and flexible interior pipe (2) is connected on the flange plate (5).
Described water-hammer arrester is to be provided with normal pressure free space (3) between the pipe (2) in body (1) and flexibility, and pipe absorbs water hammer to the free space expansion in the flexibility when water hammer is come.Also be provided with leak detection mouthful (4) on the body (1), a valve that is complementary with system pressure is installed, so that make regular check on water-hammer arrester, whether heat water valve inspection is regularly understood and is managed (2) in flexible and destroyed by water hammer and the effect that loses the elimination water hammer.According to the shunting pressure of supply water; also can give free space (3) inflation by leak detection mouthful (4), pipe (2) in protection is flexible is as long as pressure of supply water and free space inflation pressure form differential pressure; and supplying water to press is higher than the free space pressure, just can play the effect that absorbs and eliminate water hammer.
The material of the interior pipe (2) of described water-hammer arrester is withstand voltage plastic cement or pressure-resistant rubber.
It is that the inner chamber of managing (2) in flexible is provided with C shape spring clip (6) that the flexible interior pipe (2) of described water-hammer arrester is connected on the flange plate (5).
It is with behind pipe (2) flange in the flexibility that the interior pipe of described flexibility (2) is connected on the flange plate (5), is clipped between two flange plate.Flange is installed, and on the one hand normal pressure free space (3) is sealed, and the both ends of the surface flange seals when installing on the other hand, when mounted flange both sides shimming again.
The body of described water-hammer arrester (1) length is 100-500mm.
The beneficial effects of the utility model are can effectively eliminate water hammer or water hammer, better simpler water system and the liquid measure testing apparatus protected.
Description of drawings:
Fig. 1 is the utility model embodiment 1 a sectional view;
Fig. 2 is the utility model embodiment 2 a sectional view.
Embodiment:
Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing:
Embodiment 1, sees Fig. 1, and a kind of water-hammer arrester includes body 1, and two ends are provided with flange plate 5, and the endoporus of body 1 is provided with flexible interior pipe 2, and flexible interior pipe 2 is connected on the flange plate 5, behind the interior pipe of flexibility 2 flange, is clipped between two flange plate.Flange is installed, and on the one hand normal pressure free space 3 is sealed, and the both ends of the surface flange seals when installing on the other hand, when mounted flange both sides shimming again.Be provided with normal pressure free space 3 between the pipe 2 in body 1 and flexibility, pipe 2 absorbs water hammers to free space 3 expansions in the flexibility when water hammer is come.Also be provided with leak detection mouthfuls 4 on the body 1, a valve that is complementary with system pressure is installed, so that make regular check on water-hammer arrester, whether heat water valve inspection is regularly understood and is managed 2 in flexible and destroyed by water hammer and lose the effect of elimination water hammer.According to the shunting pressure of supply water, also can give free space 3 inflations by leak detection mouthfuls 4, pipe 2 in protection is flexible as long as pressure of supply water and free space inflation pressure form differential pressure, and supplies water to press and is higher than free space and presses, and just can play to absorb and the effect of elimination water hammer.The material of pipe 2 is withstand voltage plastic cement in flexible.Body 1 length is 500mm.
Embodiment 2, see Fig. 2, water-hammer arrester, and structure is identical with embodiment 1, and to be connected on the flange plate 5 be to manage 2 inner chamber to be provided with C shape spring clip 6 in flexible to pipe 2 in different is described water-hammer arrester flexible.Body 1 length is 100mm.The material of pipe 2 is pressure-resistant rubbers in flexible.
