Abstract
The invention discloses a double-layer floating ball type vacuum breaking valve. According to the key points of the technical scheme, after 4-8 upper sealing floating balls are mounted in 4-8 upper floating ball baskets, the upper floating ball baskets are fixed on an upper porous plate; 4-8 upper air inlets are formed on the upper porous plate; the upper porous plate is fixedly arranged on an upper flange of an upper cylinder; a lower sealing floating ball is placed onto a ball bracket with a damping hole; a lower floating ball basket is fixedly arranged on a middle porous plate with a middle air inlet; the lower floating ball basket is covered on the lower sealing floating ball; a lower flange of the upper cylinder, the middle porous plate and an upper flange of a lower cylinder are fixed together by using a middle-position bolt; and a lower flange of the lower cylinder is fixed with a damping porous plate by using a lower bolt. The technical scheme is widely applied to the aspect of vacuum breaking of a water turbine.
Description
Technical field:
The present invention is a kind of device that is used for water turbine macro-axis center and top cover destruction vacuum.
Background technique:
When water turbine is shut down, in the water turbine volute, produced huge vacuum, this vacuum can cause damage to water turbine, and water turbine needs a kind of vacuum breaker valve for this reason, eliminates the damage of vacuum to water turbine.Present applied ball float vacuum breaker valve is the function of anti-water hammer not, and huge water hammer energy often makes the ball float distortion cause and leaks; Do not have secondary to return water sealing device yet,, just do not have the device of secondary seal water that the water that spills has been sealed if the ball float distortion causes when leaking.So the water power plant needs the anti-water hammer of a kind of ability, and the vacuum breaker valve with secondary seal function.
Summary of the invention:
The object of the invention just provides a kind of not only anti-water hammer but also has secondary to return the related technological scheme of double-deck float-ball type vacuum breaker valve of water-stop function; It is characterized in that; After going up sealed ball floats to 4～8 and pack in the upper floating ball basket, upper floating ball basket mouth gone up the inlet hole positions corresponding to 4～8 after, be fixed on the up-hole plate; Then up-hole plate being used fixing bolt is fixed on the top cylinder upper flange; The lower seal ball float is put into the ball holder that has damping hole, and ball holder and damping orifice plate are one, on the damping orifice plate, have 4 following inlet holes; Be inserted in the ball float basket that is fixed on below the aperture plate on the lower seal ball float; And the aperture plate that has the center middle inlet hole is placed on the doffing upper flange, with the meta bolt top cylinder lower flange, aperture plate and doffing upper flange is fixed together, and is fixed together doffing lower flange and damping orifice plate with following bolt.
The technique effect that technological scheme provided by the present invention realized is such: when water turbine is shut down or in improper operating mode, produce destructive vacuum; Air will inlet hole, middle inlet hole and 4 following inlet holes get into the region of no pressure on 4～8, thereby has eliminated the region of no pressure.When not producing vacuum, the working water in the water turbine will be floated the lower seal ball float, and lower seal ball float upper end is contacted with middle air inlet seal ring, realizes the sealing to working water.When working water formed water hammer, the damping hole in the ball holder will be dissolved the energy of water hammer, guaranteed that as possible the lower seal ball float in following ball float basket is indeformable, thereby avoided leaking.In a single day following sealed ball float leaks, and go up sealed ball float for 4～8 working water is realized sealing once more, and this moment, the lower seal ball float has better energy-absorbing effect to the water hammer that working water forms.
Technological scheme involved in the present invention is simple in structure, and technique effect is good, manufacturing and very easy to use, and security of operation, long service life is the desirable vacuum breaking device of water turbine.
