Abstract
The utility model relates to a spherical butterfly valve for a transformer and belongs to the technical field of valve structures. The spherical butterfly valve for the transformer comprises a valve body, a valve element plate arranged inside the valve body and a valve shaft, wherein the end faces of the two ends of the valve element plate are both spherical, and the two ends of the valve element plate are assembled with the valve body to form a spherical matching structure. According to the spherical butterfly valve for the transformer, due to the fact that the two ends of the valve element plate are assembled with the valve body to form the spherical matching structure, the matching surface is enlarged, the matching tightness is improved, the problem of the leakage of the valve is solved, in addition, the butterfly valve can be opened or closed quite easily due to the spherical matching structure, damage on the valve element plate is avoided, and furthermore the defect that an existing butterfly valve is prone to leakage if the butterfly valve can not be completely closed in place is overcome due to the fact that the valve element plate can rotate by 360 degrees with the valve shaft as the center and the valve can be well closed even if the valve can not be closed in place by 3-5 degrees.
Description
Technical field
The utility model relates to a kind of transformer spherical butterfly valve, belongs to the valve mechanism technical field.
Background technique
The transformer butterfly valve is the crucial accessory that big-and-middle-sized transformer must use.In the prior art, the cylinder inner planes that adopt cooperate more between valve body and the valve core plate of tradition butterfly valve, the shortcoming that the fit system of this structure exists is: what can not cooperate between valve core plate and the valve body is too tight, if cooperate too tightly, valve switch is just very difficult, if do not exert oneself, just be difficult to Open valve or complete throttle down, and the closing valve of in a single day exerting oneself, valve core plate causes damage with regard to being easy to distortion, even scraps; Yet, if the defective tightness that cooperates between valve core plate and the valve body is easy to produce seepage.Above-mentioned technical problem is always the fail technical barrier that solves of current numerous butterfly valve manufacturer.
The model utility content
The purpose of this utility model is, a kind of transformer spherical butterfly valve is provided, to solve above-mentioned technical problem.
For addressing the above problem, the technological scheme that the utility model adopts is:
A kind of transformer spherical butterfly valve comprises valve body, is located at the valve core plate in the valve body, and valve shaft; It is characterized in that: the end face at described valve core plate two ends is sphere, is assembled into the sphere cooperating structure between the two ends of described valve core plate and the valve body.
Say further: described valve shaft runs through valve body, and its inner pegging graft is fixed on the center of valve core plate one end; The periphery of described valve shaft is disposed with sealant bead, pressing plate and gland nut from inside to outside; Described gland nut is enclosed within on the valve shaft, screw-thread fit locking between its outer wall and the valve body.
Beneficial effect: compared with prior art, it is the sphere cooperating structure between the two ends of valve core plate described in the utility model and the valve body, not only strengthened fitting surface, improved the tightness that cooperates, solved the leakage problems of valve, and the sphere cooperating structure makes that the opening and closing operation of butterfly valve is all very light, can not cause damage to valve core plate.In addition, valve core plate can be done 360 ° of rotations centered by valve shaft, even if there be 3-5 ° of pass not in place, valve still can well be closed, and has solved existing butterfly valve if the slight pass defective that will produce seepage not in place is arranged.
Description of drawings
Fig. 1 is longitudinal profile structural representation of the present utility model;
Fig. 2 is the reference drawing of spherical butterfly valve opening state described in the utility model;
Fig. 3 is the reference drawing of spherical butterfly valve closed condition described in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
With reference to Fig. 1, transformer spherical butterfly valve described in the utility model comprises valve body 1, is located at the valve core plate 2 in the valve body 1, and valve shaft 4.The end face at described valve core plate 2 two ends is sphere, is assembled into the sphere cooperating structure between the two ends of described valve core plate 2 and the valve body 1.
Described valve shaft 4 runs through valve body 1, and its inner pegging graft is fixed on the center of valve core plate 2 one ends; The periphery of described valve shaft 4 is disposed with sealant bead 6, pressing plate 5 and gland nut 3 from inside to outside.Described gland nut 3 is enclosed within on the valve shaft 4, screw-thread fit locking between its outer wall and the valve body 1.
Use state of the present utility model Figure 2 shows that the reference drawing of spherical butterfly valve opening state described in the utility model with reference to Fig. 2, Fig. 3; Figure 3 shows that the reference drawing of spherical butterfly valve closed condition described in the utility model.
