Abstract
A support rotation prevention structure for large-diameter butterfly valve, comprise support and valve body, support is fixedly connected with by fastening piece with valve body, and the flange that valve body upper end is made has groove, and the made flange of pedestal lower end is provided with the boss of the mutual clamping with groove.The beneficial effects of the utility model are: utilize self structure to carry out anti-rotation, structure is simple, easy for installation; And the made flange in valve body upper end having groove and the made flange of pedestal lower end, to be provided with the structure of boss easy to process, cost-saving.
Description
Art
The utility model relates to a kind of butterfly valve, particularly relates to a kind of rotation prevention structure of valve support.
Background technique
Be currently used in the large-diameter butterfly valve of nuclear power, oil, Gas Industry, usually carry out anti-rotation by surface of contact being joined the neat key of joint of brill between valve body and support, or carry out anti-rotation by increasing sleeve in the gap between connecting bolt and bolt hole to reduce gap.When moment of torsion is excessive, the stopping power of neat key of joint is not enough, and support easily rotates; Gap between connecting bolt and bolt hole is not easy to control, and makes troubles to the processing of sleeve dimensions.
Model utility content
In order to overcome the above-mentioned shortcoming of existing support rotation prevention structure, the support rotation prevention structure that the utility model provides a kind of anti-rotation effective and easy to process.
The utility model solves the technological scheme that its technical problem adopts, a kind of support rotation prevention structure of large-diameter butterfly valve, comprise support and valve body, support is fixedly connected with by fastening piece with valve body, the flange that valve body upper end is made has groove, and the made flange of pedestal lower end is provided with the boss of the mutual clamping with groove.
The beneficial effects of the utility model are: utilize self structure to carry out anti-rotation, structure is simple, easy for installation; And the made flange in valve body upper end having groove and the made flange of pedestal lower end, to be provided with the structure of boss easy to process, cost-saving.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment;
Fig. 2 is the structural representation of parts 1 in Fig. 1;
Fig. 3 is the structural representation of parts 2 in Fig. 1.
In figure: 1. valve body; 2. support; 3. groove; 4. boss.
Embodiment
As shown in Figure 1, 2, 3, a support rotation prevention structure for large-diameter butterfly valve, comprises support 2 and valve body 1, and support 2 and valve body 1 are bolted to connection, the flange that valve body 1 upper end is made has groove 3, and the made flange in support 2 lower end is provided with the boss 4 with groove 3 clamping mutually.
The present invention can also be designed to the made flange in support 2 lower end has groove, and the made flange in valve body 1 upper end is provided with the boss of the mutual clamping with groove, and the anti-rotation effect reached is the same.
