Description
Technical field
The utility model belongs to valve technology field, refers in particular to a kind of multi-functional water hammer valve.
Background technology
Water hammer is also known as water attack, and water or other liquid are in transmission process, since valve is turned on and off suddenly, water pump is unexpected
Stop, opening and closing the reasons such as guide vane suddenly, makes flow velocity that suddenly change occur, while pressure generates the phenomenon that fluctuating widely.Due to
Tube wall is smooth, and under the action of inertia, waterpower is rapidly reached maximum to follow-up flow, and generates destruction, and here it is hydraulicss
" water hammer effect " in the middle, that is, positive water hammer.On the contrary, close valve throw open or water supply pump startup after, can also produce
Unboiled water is hammered into shape, is negative water hammer, but big without the former.Because turn on pump, termination of pumping, controlled valve are excessively quick, the speed of water is made to occur drastically
Variation, water hammer caused by especially unexpected termination of pumping can destroy pipeline, water pump, valve, and water pump is caused to invert, ductwork pressure
Reduce etc..Water hammer effect has great destructiveness：Pressure is excessively high, will cause the rupture of pipe, conversely, pressure is too low and can cause
The collapsing of pipe can also damage valve and fixing piece.In the extremely short time, the flow of water is from zero suddenly to metered flow.Due to
Fluid has kinetic energy and a degree of compressibility, therefore the great variety of flow will cause to pipeline within the extremely short time
The excessively high and too low impact of pressure.
The structure of most of water-hammer arresters is all made of sleeve, spring, piston and sealing ring, and water-hammer arrester is most
All it is to first pass through threaded connection to be fixed on connector, then be fixed on three-way valve by connector, by the fixation of both sides, as long as having
Do not fixed at as soon as, sealing effect it is bad, then water is likely to ooze out from junction, water resource will waste.It is common
Water-hammer arrester be all by spring elasticity by piston reset, access times have been more than the fatigue strength of spring, then this
Water-hammer arrester will fail, and the water-hammer arrester being fixed on valve passes through prolonged use, can gradually loosen, will
Influence the effect that water hammer is eliminated.
