sanitary bottom ball valve

 Main features of the product
 
1. It adopts three piece structure, which is easy to install, disassemble and maintain. The welding ring joint design is adopted at the connection end of the tank, which reduces the difficulty of welding at the bottom of the tank, reduces the possibility of leakage at the same time, and improves the sealing performance. The outlet end can be designed as quick installation, welding or threaded interface according to the needs of customers.
 
2. The hyperboloid structure full ball sealing ring design ensures that there is no dead angle in the body cavity of the tank bottom ball valve, which can completely empty the medium. It is also very easy to clean and disinfect the valve and pipeline. It solves the problem that the dead angle of the body cavity often causes residual medium, which will affect the freshness of the medium, and even pollute the medium and affect the safe use of the medium; The hyperboloid structure design can not only ensure the sealing between the ball and the sealing ring, but also reduce the friction between the sealing ring and the ball, and reduce the torque of the valve switch.
 
3. When the ball valve at the bottom of the tank is closed, the residual medium in the flow channel of the ball can not be completely emptied. However, with the ball through-hole structure design, the residual medium in the ball can be completely emptied with the ball through-hole facing to the outlet end of the valve.
 
4. The platform structure design of direct installation driving device is adopted to facilitate the installation of various actuators and realize intelligent, mechanized and remote operation.
 
Main research contents
 
1. The determination of the structure of full ball seal ring generally has dead angle, which is easy to residual media and affects the health and safe use of media. The structure of full ball seal ring seals the space of residual media and eliminates the possibility of residual media. Hyperboloid structure design is adopted for the whole ball sealing ring structure. The hyperboloid structure design can not only ensure the sealing between the ball and the sealing ring, but also reduce the friction between the sealing ring and the ball, and reduce the torque of the valve switch.
 
2. The ball through-hole structure determines that when the ball valve at the bottom of the tank is closed, the ball through-hole structure design is adopted. When the ball valve at the bottom of the tank is closed, there will still be residual media in the flow channel of the universal ball valve, which can not be completely emptied. After adopting the ball valve structure design, the residual media in the ball can be completely emptied at the outlet end of the ball valve, and there is no residue.
