Description
Technical field
The utility model relates to field of mechanical technique, more particularly, to a kind of water-hammer arrester and water hammer cancellation element.
Background technique
Water hammer is, due to the inertia of pressure flow, to generate water impact in unexpected power failure or when valve closes too fast
Wave, it is the same as hammer, so being water hammer.The power that rivers shock wave generates back and forth, it is very big sometimes, to destroy valve
And water pump.
When electric water pump full voltage starting, within the time less than 1s, rated speed can be accelerated to from stationary state, the
Flow in one pipeline then increases from zero to metered flow.Since fluid has momentum and a degree of compressibility, so,
The impact that the change dramatically of flow will cause pressure too high or too low in first pipe, and there is " cavitation " phenomenon.Pressure
Impact will make tube wall stress and generate noise, like hammer tap pipe, referred to as " water hammer effect ".
" water hammer effect " refers to that inside water pipe, inside pipe wall is smooth, and water flowing is freely.When open valve is closed suddenly,
Water flow can generate a pressure to valve and tube wall, mainly valve.Since tube wall is smooth, effect of the subsequent water flow in inertia
Under, it is rapidly reached maximum, and generate destruction, here it is " water hammer effects " in hydro science, that is, positive water hammer.In water
This factor will be considered in sharp first pipe construction.On the contrary, the valve closed can also generate water hammer, cry after throwing open
Negative water hammer also has certain destructive power, but big without the former.
Water hammer effect has great destructiveness: pressure is excessively high, will cause the rupture of pipe, conversely, pressure is too low and can lead
The collapsing for causing pipe, can also damage valve and fixing piece.
