Abstract
The utility model relates to a butterfly valve without pin connection in an opposite-clamped type. The structure characteristic is that the rotation axle hole of a butterfly plate and the matched portion of an upper rotation axle are in the convex-concave shape of opposed complementation. An upper half axle and a lower half axle are respectively fixed by an upper taper pin and a lower taper pin on the wall of the rotation axle hole of a valve body. The phenomena of local corrosion and medium leakage on the combination portion of plate pins easy to be generated by the connection of the butterfly plate and the taper pins of the rotation axle caused by the pipeline medium are avoided. The upper half axle can be continuously drive the butterfly plate to rotate and the lower half axle can stably support the butterfly plate. The hub breaking structure of the rotation axle hole of the butterfly plate improves the flow capacity of the pipeline with energy saving and material saving.
Description
The utility model relates to a kind of valve class technology, and particularly a kind of wafer type does not have pin and connects butterfly valve.
In the prior art, butterfly plate takes taper pin to be connected with rotating shaft mostly, and the junction of taper pin and butterfly plate is easy to generate the seepage of medium, is unfavorable for that pipeline seals fully.The local etching phenomenon of pin plate joint causes the reliability of taper pin transmission to reduce simultaneously; In addition, the butterfly plate rotary shaft hole adopts whole hub structure, makes the pipeline negotiability poor.
The purpose of this utility model is to overcome the deficiency of known technology and provides a kind of wafer type not have pin connection butterfly valve.
The purpose of this utility model is achieved in that
The part of butterfly plate upper spindle hole of the present utility model and upward rotating shaft cooperation is the relative complementary shape of convex-concave.
On the upper and lower rotating shaft hole wall of valve body of the present utility model and two annular grooves that pass upper and lower rotating shaft edge a pair of location taper pin is set.
Butterfly plate rotary shaft hole of the present utility model adopts hub broken structure, promptly only install, the upper and lower rotary shaft hole of the butterfly plate place of lower rotary shaft forms a pair of axial protuberance, butterfly plate center and edge section thereof are a continuous level.
The utility model accompanying drawing is as follows:
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the complete section side view of Fig. 1;
Fig. 3 is the spline linkage structure schematic representation of butterfly plate upper spindle hole of the present utility model and last rotating shaft;
Fig. 4 overlooks for the part of Fig. 3 and cuts open schematic representation;
Fig. 5 is butterfly plate upper spindle hole of the present utility model and last rotating shaft six side's linkage structure schematic representation.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
The utility model has the advantages that, owing to take the complementary syndeton of butterfly plate and upper rotating shaft convex-concave, the butterfly plate surface does not have pin and connects, make the pipeline medium can not produce dielectric leakage and local corrosion phenomenon that butterfly plate and rotating shaft taper pin ease of connection occur in plate pin junction, improved sealing and reliable transmission. Rotating shaft is divided into upper and lower two semiaxis, and the butterfly plate shaft hole adopts hub broken structure, makes the butterfly plate centre not have rotating shaft to pass the axial protuberance of formation, has improved negotiability, energy-saving material-saving. Can prevent upper and lower two upper and lower plaies of half way around owing on valve body rotating shaft hole wall, fix respectively two semiaxis with taper pin again, make semiaxis connect the moving butterfly plate of strip winding and rotate that second stabilizer shaft ground supports butterfly plate.
