Embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description：
Refer to Fig. 1, Fig. 2, a kind of slow pressure ball valve of the utility model offer, including valve body 1 and located at the both sides of valve body 1
Water inlet end 2, water side 3, valve body 1 are provided with mesopore 4, the valve rod 5 to match with it are provided with mesopore 4, and the one end of valve rod 5 passes
Mesopore 4 is simultaneously connected with handle 6, and the other end of valve rod 5 is located in valve body 1 and is connected with opening and closing element 7, and the both ends of opening and closing element 7 are provided with
Delivery port 9 similar in the water inlet 8 relative with water inlet end 2 and water side 3；Covered covered with one the port of water inlet 8
Drainage plate 10；The port of delivery port 9 is covered with a fixed plate 11 covered；The drainage plate 10 and fixed plate 11 it
Between be provided with a fixing axle 12；The drainage plate 10 is provided with an annular inlet opening 13 to be connected with the inner space of opening and closing element 7；Institute
Fixed plate 11 is stated provided with an annular apopore 14 to be connected with the inner space of opening and closing element 7；The external diameter of annular apopore 14
More than or equal to the annular external diameter of inlet opening 13, the annular internal diameter of apopore 14 is less than the annular internal diameter of inlet opening 13；The fixing axle 12
Outer to be equipped with a slow pressure capsule 15, it is elastic material to delay pressure capsule 15；The slow pressure capsule 15 is provided with one relative to the side of drainage plate 10
Opening 16；A connecting plate 17 is provided with the opening 16, connecting plate 17 covers opening 16；The connecting plate 17 is provided with some
The slow pressure hole 18 being circularly and evenly distributed；The slow pressure capsule 15 is externally provided with a water conservancy diversion bowl 19；The water conservancy diversion bowl 19 is provided with some
The limbers 20 being circularly and evenly distributed；The port of water conservancy diversion bowl 19 is provided with a limiting section 21 to match with the inwall of opening and closing element 7.
The inwall of opening and closing element 7 is provided with a spacing ring 22, the neighbouring slow pressure capsule 15 of spacing ring 22 side relative with delivery port 9
Wall.
The outer surface of limiting section 21 is provided with some equally distributed anti-skid bulges 23.
The water conservancy diversion bowl 19 and annular inlet opening 13 are coaxial, and the external diameter of water conservancy diversion bowl 19 is equal to or less than annular inlet opening 13
Internal diameter.
Application method of the present utility model is as follows：
When hydraulic pressure is normal, the current in pipeline will enter to keying after water inlet end 2 by annular inlet opening 13
In part 7, then flow away, finally flowed out from annular apopore 14, and pass through water outlet towards delivery port 9 under the guiding of water conservancy diversion bowl 19
End 3 is delivered to duct end, when current are constantly flowed into opening and closing element 7, can be passed through into the current in opening and closing element 7 on connecting plate 17
Slow pressure hole 18 enter in slow pressure capsule 15, but the normal current of hydraulic pressure can extremely have to extruding force caused by slow pressure capsule 15
Limit, therefore slow pressure capsule 15 is not in obvious deformation, because the annular external diameter of apopore 14 is more than or equal to outside annular inlet opening 13
Footpath, the annular internal diameter of apopore 14 are less than the annular internal diameter of inlet opening 13, ensure that the aperture of annular apopore 14 is big, so as to ensure
Water-carrying capacity, the normal current of hydraulic pressure can be discharged quickly outside opening and closing element 7 by annular apopore 14, current hydraulic pressure is not opened
The influence of part in closing member 7.
When hydraulic pressure is too high, current in pipeline can then enter opening and closing element 7 quickly through annular inlet opening 13, and when first
Between full of in opening and closing element 7, the too high current of hydraulic pressure can then pass through slow pressure hole 18 and rapidly enter in slow pressure capsule 15, and slow pressure capsule 15 is entered
Row extruding, because slow pressure capsule 15 is quality of rubber materials, it can enter row buffering by natural resiliency to High-Pressure Water, with High-Pressure Water
Constantly slow pressure capsule 15 is extruded, slow pressure capsule 15 is quickly strutted, and is delayed pressure capsule 15 both sides and is gradually expanded towards the inwall of opening and closing element 7
Exhibition, when hydraulic pressure is high, the water conservancy diversion bowl 19 of the slow periphery of pressure capsule 15 is then to be increasingly closer to the inwall of opening and closing element 7, when the end of water conservancy diversion bowl 19
When the limiting section 21 in portion is in contact with the inwall of opening and closing element 7, delaying pressure capsule 15 almost will be completely obscured inside opening and closing element 7, delays pressure capsule
It is in contact in 15 maximum areas with High-Pressure Water, now delays in pressure capsule 15 and be full of current, slow pressure capsule 15 can enters as water cushion
Exercise and use, delay pressure capsule 15 and flowed by the current of inside to enter row buffering to the High-Pressure Water constantly entered in opening and closing element 7, and limit
Being bonded between position portion 21 and the inwall of opening and closing element 7 can ensure that slow pressure capsule 15 will not be washed away by High-Pressure Water, slow pressure capsule 15 is begun
Maximum Contact face is kept with High-Pressure Water eventually, ensures optimal slow pressure effect, enables the current hydraulic pressure in pipeline constantly slow
Recover in punching to normal hydraulic pressure, avoid the occurrence of that hydraulic pressure is excessive to cause pipeline breaking and the impaired situation of duct end, opening and closing
After part 7 is covered by slow pressure capsule 15, annular can be flowed to by the limbers 20 on water conservancy diversion bowl 19 into the current in opening and closing element 7 and gone out
Water hole 14, the presence of limbers 20 become the runner of script in order to which small-bore is flowed, the same effect with buffering.
The inwall of opening and closing element 7 is provided with spacing ring 22, the neighbouring slow pressure capsule 15 of spacing ring 22 side wall relative with delivery port 9, limit
The presence of position ring 22 can play a part of auxiliary stopper, prevent the situation that the slow pressure capsule 15 after strutting is bent by High-Pressure Water,
Ensure the buffering effect of slow pressure capsule 15.
The outer surface of limiting section 21 is provided with some equally distributed anti-skid bulges 23, and the presence of anti-skid bulge 23 can improve limit
Friction level between position portion 21 and the inwall of opening and closing element 7, improve the steadiness after slow pressure capsule 15 is softened.
Water conservancy diversion bowl 19 and annular inlet opening 13 are coaxial, and the external diameter of water conservancy diversion bowl 19 is equal to or less than the interior of annular inlet opening 13
Footpath, therefore the current entered from annular inlet opening 13 directly fall within the surface of water conservancy diversion bowl 19, ensure that water conservancy diversion bowl 19 is normal in hydraulic pressure
In the case of play the effect of water conservancy diversion, will not current flowing cause to hinder.
