Description

Novel simple water hammer cancellation element
Technical field
The invention belongs to water hammer cancellation element fields, and in particular to a kind of novel simple water hammer cancellation element.
Background technique
Water hammer, since certain outside cause such as valve is closed suddenly or is had a power failure suddenly, is made in pipeline closed system The flow velocity for obtaining water reduces suddenly, and the impact valve of potential energy entrained by water and pipeline, generate water flow impact pressure, just as hammer is beaten at this time Tube wall is beaten, causes water hammer to have greatly destructive, often results in pipeline or valve is destroyed.And existing water hammer eliminates skill The problem of device, is commonly present that structure is complicated, cumbersome, higher cost, cannot effective large-scale promotion.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of novel simple water hammer cancellation element, be able to solve pipeline by The outside causes such as closing or have a power failure suddenly in valve causes the flow velocity of water to increase suddenly, is increased to normal stream suddenly to tube wall pressure Tens times or more when state and make the problem of pipeline or valve are by destroying.
To achieve the above object, the technical solution adopted by the present invention is that:A kind of novel simple water hammer cancellation element, including it is defeated The guard box on pipeline is arranged in water pipe, pipeline valve, and through hole is provided between guard box and pipeline and is arranged in pipeline valve The water inlet of door is equipped with movable pressure valve at through hole and is opened and closed by hydraulic pressure, and movable pressure valve is material of rectangular channel And in length ratio 1:Two sides at 3 be equipped with movable pressure valve shaft or with the perforative hole of valve axis, movable pressure valve shaft Or the both ends of perforation axis are separately fixed in guard box and perpendicular to movable pressure valve shaft or the corresponding side wall lower ends of perforation axis Pipeline on.The water flowed into guard box equipped with impeller circulation.
The valve shaft is the axis of the correspondence side wall lower ends in guard box and perpendicular to valve shaft, and axis is equipped with Moving casing;Movable pressure valve is stated to be fixedly connected equipped with axis axis hole with casing.
The guard box bottom side surrounding Opening length is less than guard box bottom side surrounding length, the movable pressure valve surrounding Length be greater than the side wall surrounding Opening length on pipeline, the long end of movable pressure valve is located in guard box, movable pressure valve The short end of door is located in pipeline.
Movable pressure valve both ends and guard box wall box contact position are equipped with cushion rubber bumper.
Impeller is equipped in the guard box, the impeller is fixed on impeller shaft, the impeller shaft and guard box pair The impeller shaft turn hole on side wall is answered to be adapted.
The impeller shaft is arranged in parallel with movable pressure valve shaft, and is located at the middle position of guard box.
Guard box two sidewalls bottom is equipped with the groove at carrying lantern ring both ends, and groove is adapted with lantern ring both ends, groove Inner wall is equipped with valve shaft pad, and guard box two sidewalls bottom connects by the way that valve shaft pad and movable pressure valve shaft are fixed It connects.
It is described to be equipped with spring retaining plate, pulling force is equipped between the spring retaining plate and the long slab of movable pressure valve Spring.
The tension spring is the identical groups of springs of spring ratio disposed in parallel.
The tension spring limited compression length is identical as spring retaining plate height.
The beneficial effects of the invention are as follows:The device can effectively solve existing pipeline since pipeline valve is closed or stopped suddenly The outside causes such as electricity cause the flow velocity of water to increase suddenly, generate water flow impact pressure, beat just as hammer and beat tube wall, have great Destructiveness causes the problem of pipeline or valve are by destroying.Movable pressure valve right length of the invention is left length Three times, so that the pressure suffered by movable pressure valve right side when water hammer occurs is significantly greater than left pressure, enable water flow It is flowed into from right side, left side outflow, movable pressure valve both ends are equipped with cushion rubber bumper at protection box body, avoid valve frequency Numerous cabinet of having more than needed with guard box bottom side causes device and is destroyed;Guard box bottom side surrounding Opening length is less than guard box bottom side Surrounding length, the surrounding length of movable pressure valve are greater than the side wall surrounding Opening length on pipeline, the length of movable pressure valve End is located in guard box, and the short end of movable pressure valve is located in pipeline.Make movable pressure valve and guard box bottom notch mistake It is full of and agrees with, avoids movable pressure valve and guard box bottom from gap occur, influence device effect, the most tight reduction length of groups of springs It is identical as groups of springs fixed plate height, so that the maximum rotation angle of movable pressure valve is 45 degree, avoid movable pressure valve Door is collided with impeller.
