Description
Technical field
Pipeline control ball valve field is the utility model is related to, more particularly to a kind of Flow-rate adjustment V-type ball valve valve
Core.
Background technology
In the prior art, the most frequently used structure of V-type regulation ball valve is the V-type ball valve of the spherical cap shape of about 1/4 ball.The knot
The products characteristics of structure：Single seat, v-notch regulation is accurate, and ball crown type valve element makes valve mechanism compact, but in actually manufacture and application
In still have distinct issues：Being mainly reflected in the valve good cycle of operation does not grow.Particularly in the case of High Pressure Difference, driving
Stability is poor；Bore valve tightness bigger than normal is worse, the valve element of spherical cap structure, and its sealing stiff dough manufacture difficulty is big, is difficult to ensure card
Design the circularity needed；Noise when valve is just opened is big.
Utility model content
The utility model passes through change mainly solving the technical problems that provide a kind of Flow-rate adjustment V-type ball valve valve element
Sphere structure, to reach the purpose of Flow-rate adjustment and noise reduction.
To solve above-mentioned technical purpose, the technical solution adopted in the utility model is as follows：
A kind of Flow-rate adjustment V-type ball valve valve element, it is characterised in that：Including spheroid and the gudgeon that is arranged on above and below spheroid,
The flow of media passage with V shaped hole is through with spheroid, and spheroid is provided with discharge orifice, V-type perpendicular to flow of media passage side
Abacus is set in hole.
Further, it is provided with valve rod slot at the top of the upper gudgeon of the spheroid.
Further, the flow of media passage includes circular arc circulation passage and v-notch passage.
Further, the orifice plate is multilayer, and every layer of orifice plate is inwardly sequentially reduced along V shaped hole, and on every layer of orifice plate
It is provided with multiple throttle orifices.
Further, the multiple rows of multiple row arrangement of the throttling aperture layer, and on the throttle orifice on every layer of orifice plate and next layer of orifice plate
Throttle orifice be staggered.
The beneficial effects of the utility model are：The situation of prior art is different from, the utility model valve stem end drives ball
Body does 90 degree of revolutions to realize connection, cut-out or regulation with pipeline medium, the special v-notch of spheroid and valve base chamber it is relative
Motion is accurately controlled pipeline flow, and can reach high regulation sensitivity.
Secondly, the moment opened in valve flows through multilayer orifice plate by forced medium, step by step by the throttle orifice stream of orifice plate
Go out, and be dispersed in larger space, the rate of outflow is completely controlled, reach step pressure reducing, control flow and pressure it
Purpose.No matter pressure drop size, the resistance of these bends causes throttle orifice of the medium through multiple rows of multiple row, and in outlet, the speed of outflow is big
It is big to reduce.By decompression, the pressure of medium is maintained all the time on the saturation pressure for vaporization of medium, show so as to keep away rabbit cavitation
As eliminating unsafe factor, while medium outflow noise drops in controlled range.

Embodiment
The utility model is described further with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1-Figure 3, a kind of Flow-rate adjustment V-type ball valve valve element, including spheroid 2 and spheroid is arranged on about 2
Gudgeon 14, the flow of media passage 7 with V shaped hole 8 is through with spheroid 2, and spheroid 2 is opened perpendicular to the side of flow of media passage 7
There is discharge orifice 11, abacus 9 is set in V shaped hole 8.
The top of upper gudgeon 14 of the spheroid 2 is provided with valve rod slot 15.The flow of media passage 7 circulates including circular arc
Passage and v-notch passage.The orifice plate 9 is multilayer, and every layer of orifice plate 9 is inwardly sequentially reduced along V shaped hole 8, and in every layer of hole
Multiple throttle orifices 10 are provided with plate 9.The multiple rows of multiple row arrangement of 10 layers of throttle orifice, and the throttle orifice 10 on every layer of orifice plate 9 is with
Throttle orifice 10 on one layer of orifice plate 9 is staggered.
In actual use, the gudgeon up and down 14 of spheroid 2 plays a part of the fixation of assistant sphere 2, and is laterally hung down in spheroid 2
Directly it is designed with runner hole direction and the orifice plate 9 of stacking is provided with larger discharge orifice 11, the V shaped hole 8 of spheroid 2, and every layer
Orifice plate 9 is sequentially reduced, and the throttle orifice 10 on orifice plate 9 is also sequentially reduced.
In the moment that valve opens, multilayer orifice plate 9 is flowed through by forced medium, flowed step by step by the throttle orifice 10 of orifice plate 9
Go out, and be dispersed in larger space, the rate of outflow is completely controlled, reach step pressure reducing, control flow and pressure it
Purpose.No matter pressure drop size, the resistance of these bends causes throttle orifice 10 of the medium through multiple rows of multiple row, in the speed of outlet outflow
Substantially reduce.By decompression, the pressure of medium is set to maintain all the time on the saturation pressure for vaporization of medium, so as to keep away rabbit cavitation
Phenomenon, unsafe factor is eliminated, while medium outflow noise drops in controlled range.
Driving stem end rotation under the utility model external driver device and control element collective effect, valve stem end band
Dynamic spheroid 2 does 90 degree of revolutions to realize connection, cut-out or regulation with pipeline medium, spheroid 2 special v-notch and valve base chamber
Relative motion pipeline flow is accurately controlled, and high regulation sensitivity can be reached.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
