Description
Technical field
The utility model relates to a kind of water systems, more particularly to one kind can eliminate the DI water of water hammer effect for water system
System, belongs to water system field.
Background technique
Water hammer effect be a kind of figuratively method it refer to feed pump when starting and stopping, water impact pipeline generates
A kind of serious water attack.Due to inside water pipe, inside pipe wall be it is smooth, water flowing is freely.When open valve is closed suddenly
Or feed pump stops, water flow can generate a pressure to valve and tube wall, mainly valve or pump.It is subsequent since tube wall is smooth
Under the action of inertia, waterpower is rapidly reached maximum to water flow, and generates destruction, and here it is " the water hammer effects in hydraulics
Answer ", that is, positive water hammer.On the contrary, close valve throw open or water supply pump startup after, can also generate water hammer, be negative water
Hammer, but it is big without the former.
Because turn on pump, termination of pumping, controlled valve are excessively quick, make the speed of water that change dramatically occur, especially unexpected termination of pumping is drawn
The water hammer risen, can destroy pipeline, water pump, valve, and water pump is caused to invert, and ductwork pressure reduces etc..Water hammer effect has greatly
Destructiveness: pressure is excessively high, will cause the rupture of pipe, conversely, pressure is too low and will lead to the collapsing of pipe, can also damage valve
Door and fixing piece.In the extremely short time, the flow of water is from zero suddenly to metered flow.Due to fluid with kinetic energy and to a certain degree
Compressibility, therefore the great variety of flow will cause impact excessively high to the pressure of pipeline and too low in a very short period of time.
Compression shock will make tube wall stress and generate noise, like hammer taps pipeline, therefore referred to as water hammer effect.
Current tradition DI water supply system is in order to eliminate water hammer effect, usually using water-hammer arrester, including cylinder, cylinder
Bottom by the way of being spirally connected the mode of bottom cover fix, be bolted with connector in the opening of cylinder, connector is equipped with triple valve, cylinder
It is equipped with plug in vivo.This water-hammer arrester can achieve to a certain extent eliminate water hammer effect effect, but for a long time with
It is past, due to the influence of water hammer effect, the sealed bottom of cylinder is caused to reduce, and the control operation of triple valve also seems extremely
Cumbersome, working efficiency is extremely low, and the accessory needed is extremely more, and structure is also extremely complex, causes certain shadow to production and processing
It rings.
In conclusion how to provide a kind of DI water supply system that can eliminate water hammer effect just becomes those skilled in the art
