Embodiment
The utility model is further described in conjunction with Fig. 1, Fig. 2, a kind of multi-function ball stops valve, including valve body 1, valve
Seat 2, valve rod 3 and operating mechanism 4, the end of described valve rod 3 are also associated with spheroid 5, and the top of described spheroid 5 is provided with groove
54, the described end of valve rod 3 is arranged in groove 54.Described spheroid 5 is sealed with valve seat 2 to be coordinated, the inner chamber of described spheroid 5
Interior to be provided with baffle 6, the exit of the inner chamber of described spheroid 5, which is provided with mounting groove 52, described mounting groove 52, is provided with support
53, described baffle 6 is arranged on support 53.Runner 51, described baffle 6 are formed between described baffle 6 and spheroid 5
The runner 51 formed between spheroid 5 is venturi runner.Flap 61 is additionally provided with described baffle 6, described flap 61 is wrapped
Include the non-return position that sealing coordinates at the import with the inner chamber of spheroid 5 and the excessively stream position opened with flap 61.Described water conservancy diversion
Guide rod 7 is provided with body 6, described guide rod 7 slides with baffle 6 to be coordinated, and described flap 61 is located at the one end of guide rod 7, described
Guide rod 7 is integrally formed with flap 61.Back-moving spring 62 is additionally provided between described flap 61 and baffle 6.
It is provided with described baffle 6 in the middle of support base 63, described support base 63 and is provided with through hole 64, described guide rod 3
Through through hole 64, described back-moving spring 62 is arranged between support base 63 and flap 61.
Baffle is provided with the inner chamber that the utility model passes through spheroid, runner, institute are formed between described baffle and spheroid
It is additionally provided with flap on the baffle stated, seals and coordinate at the import of described flap and spheroid, can not only block and on-tube
The function of the function in road, also non-return, so as to realize the effect of low pressure drop, low noise, minimum standard-sized sheet flow velocity and water impact preventing, flap
Turn-off transient, the pressure change of valve port outlet side does not produce the phenomenon that local pressure increases suddenly than more uniform, weakens flap pass
Effect of water hammer when closing.
Multi-function ball stops valve operation principle, when medium enters axial flow type check valve through entrance, acts on flap
Medium static pressure and fluid momentum overcome the spring force to open flap, and fluid passes through runner.Area of passage reduces at runner aditus laryngis,
Pressure differential is formed before and after flow velocity increase, pressure reduction, flap, under fluid momentum and the force action of pressure differential, flap is promoted
Overcome spring force, continue on valve.
When flow velocity continues to increase to valve minimum standard-sized sheet speed Vo, valve wide open, now spring force and the punching of flap fluid
The F balances of making a concerted effort of amount and pressure differential.When flow velocity is more than Vo, flap will not be fluctuated and waved with fluid velocity, now flow resistance system
Number is minimum and constant.Flow velocity to Vo be gradually reduced when, if the F that makes a concerted effort acted on flap is less than spring force, valve starts to do
Closedown campaign, because flap shutoff stroke is short, flap is closed rapidly in place.Now fluid reflux is restricted, and back-flow velocity is very
It is small, water attack harm is reduced, the plant equipment such as pipeline and water pump are protected.
Detect that data are learnt by computer CFD analogue simulations and model machine flow resistance, compared with general check valve runner, use
Vortex and differential pressure gradients during venturi runner at the import of axial flow type check valve is all smaller.The generation of whirlpool is reduced,
Improve valve export end Fluid pressure recovery capability.
Flap turn-off transient, the pressure change of valve port outlet side does not produce the phenomenon that local pressure increases suddenly than more uniform,
Weaken effect of water hammer when flap is closed.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under the utility model thinking belong to protection domain of the present utility model.It should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
