The difference between sanitary valves and industrial valves

The difference between sanitary valves and industrial valves Sanitary valves are generally made of 304SS or 316 stainless steel. After the production and processing are completed, they have undergone special treatment. In many aspects, they are incomparable to industrial valves, such as cleanliness, simple installation methods, etc. , This is the valve specially made for food, medicine and other industries. Industrial valves are generally formulated according to the needs of use, mainly for long service life and flexible operation in a high temperature and high pressure working environment. There is no sanitary valve in appearance and interior smooth and beautiful, but in many places they cannot be replaced by sanitary valves. . The closed type combined seat sanitary ball valve mainly solves the problems of short service life and poor sealing performance of the existing sanitary ball valves. It is characterized in that: the valve seat of the product and the valve body are fitted with a groove, the groove of the product is provided with an elastic member, one end of the elastic member of the product is in contact with the bottom surface of the groove, and the other end is The end faces of the valve seat are in contact, and there is a gap between the valve seat of the product and the valve body that allows the valve seat to move within a certain range. Because the ball valve is equipped with an elastic member, the elastic member plays a buffering role to reduce the friction between the valve seat and the ball, and the elasticity generated by the elastic member itself makes the sealing performance between the valve seat and the ball unaffected, which can guarantee both Good sealing performance can reduce the degree of wear and effectively extend the service life of the product. The sanitary ball valve of the sanitary valve series includes the left and right seals of the ball valve. Except for the stem hole and through hole, the sealing surface of the ball valve forms a spherical cavity that completely surrounds the sphere. The radius of the spherical cavity is equal to that of the sphere. Radius, the sphere is arranged in a liquid-tight and dynamic fit. Since the sealing surface of the sanitary ball valve of this product completely wraps the sphere, when it is closed, there is no gap or space for the medium in the sphere to leak, and the medium will be sealed in the sphere until the next time it is opened; in addition, When cleaning, you only need to pass clear water into the ball valve and open and close several times to clean the residue in the valve. It is very convenient and suitable for use in occasions or industries with high sanitary requirements.
