Sanitary Butterfly Valve How to ensure good sealing performance?

The closed combination valve seat sanitary butterfly valve mainly solves the problems of short service life and poor sealing performance of the existing sanitary ball valve. It is characterized in that: a groove is provided at the matching position of the valve seat and the valve body of the product, and an elastic component is provided in the groove of the product. One end of the elastic component of the product contacts the bottom surface of the groove, and the other end contacts the end surface of the valve seat of the product. There is a gap between the valve seat and the valve body of the product so that the valve seat can move within a certain range. Since the ball valve is provided with an elastic component, the elastic component plays a buffering role to reduce the friction between the valve seat and the ball, and the elasticity generated by the elastic component itself does not affect the sealing performance between the valve seat and the ball, which can ensure good sealing performance and reduce the degree of wear, and effectively extend the service life of the product.

The sanitary butterfly valve includes a spherical cavity that completely surrounds the sphere, except for the valve stem hole and the through hole, and the radius of the spherical cavity is equal to the radius of the sphere, and the sphere is arranged in a liquid-tight dynamic fit. Since the sealing surface of the sanitary butterfly valve of this product completely wraps the sphere, there is no gap or space for the medium in the sanitary butterfly valve to leak out when it is closed. The medium will be sealed in the sphere until the next opening. In addition, when cleaning, you only need to pass clean water into the ball valve and open and close it several times to clean the residue in the valve. It is very convenient and suitable for use in occasions or industries with high hygiene requirements.
