Abstract
The utility model relates to a kind of adjustment ball valve being provided with anti-crushing valve seat, comprise valve body, in valve body, bottom is provided with valve seat, spheroid is provided with above valve seat, the inner ring of valve seat is provided with V-baffle in medium injection side, after adopting above technological scheme: on the basis of existing technology, add one piece of V-baffle, due to the existence of V-baffle, medium first can impact V-baffle, enter again in valve body, due to the setting of the angle of V-baffle, medium is by the central point of V-baffle, like this medium upwards can spray along the central point of V-baffle, directly penetrate from the outlet of valve body, instead of the sidewall directly sprayed to valve body, doing so avoids valve body of the prior art and usually occur damaged situation.
Description
Technical field
The utility model belongs to adjustment ball valve field, is specifically related to a kind of adjustment ball valve being provided with anti-crushing valve seat.
Background technique
Adjustment ball valve is applied in industrial fluids process, for automation regulable control, but range of flow is quite large sometimes for medium, then require to regulate the spheroid of ball valve when valve opening, require that the scope regulated is many, produce pipeline flow-direction pressure constant, namely see Fig. 1, medium can impact the sidewall of valve body, the outlet of valve body is flowed to again along sidewall, long media impingement body wall, easily occurs that the sidewall of valve body is thinning by media impingement, finally causes perforation.
Summary of the invention
The utility model in order to solve the technical problem mentioned in background technique, then provides a kind of adjustment ball valve being provided with anti-crushing valve seat.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
Be provided with an adjustment ball valve for anti-crushing valve seat, comprise valve body, in valve body, bottom is provided with valve seat, is provided with spheroid above valve seat, and the inner ring of valve seat is provided with V-baffle in medium injection side.
The upper surface of V-baffle and the excircle of spheroid tangent.
The angle of two hypotenuses of V-baffle is greater than 120 degree.
After adopting above technological scheme: on the basis of existing technology, add one piece of V-baffle, due to the existence of V-baffle, medium first can impact V-baffle, then enters in valve body, due to the setting of the angle of V-baffle, medium is by the central point of V-baffle, and like this medium upwards can spray along the central point of V-baffle, directly penetrates from the outlet of valve body, instead of the sidewall directly sprayed to valve body, doing so avoids valve body of the prior art and usually occur damaged situation.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing valve seat;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the plan view of valve seat.
Embodiment
See Fig. 1, Fig. 2, Fig. 3, a kind of adjustment ball valve being provided with anti-crushing valve seat, comprise valve body 1, in valve body 1, bottom is provided with valve seat 2, is provided with spheroid 3 above valve seat 2, and the inner ring of valve seat 2 is provided with V-baffle 4 in medium injection side.
All parts of the present utility model is explained, see Fig. 2, Fig. 3:
1) upper surface of V-baffle 4 and the excircle of spheroid 3 tangent.
2) angle of two hypotenuses of V-baffle 4 is greater than 120 degree.
After adopting above technological scheme: on the basis of existing technology, add one piece of V-baffle 4, due to the existence of V-baffle 4, medium can first impact V-baffle 4, enter in valve body 1 again, due to the setting of the angle of V-baffle 4, medium is by the central point of V-baffle 4, like this medium upwards can spray along the central point of V-baffle 4, directly penetrate from the outlet of valve body 1, instead of the sidewall directly sprayed to valve body 1, doing so avoids valve body 1 of the prior art and usually occur damaged situation.
