Reaction kettle with the selection of discharge valve
Oct 12, 2020

For autoclave with large volume, a valve is required to be added at the bottom of the autoclave in order to facilitate discharging or reduce the opening times of the lid, so as to facilitate material discharge from the bottom. For the user, the choice of valve form is very important, because if the valve selected does not match the characteristics of the reaction material, valve damage or high residual material in the autoclaves will often occur. Generally speaking, there are a variety of valves for users to choose autoclave, mainly ball valve, exhibition valve (or known as the bottom valve) these two kinds.


According to the use of different material state of the material, the ball valve is mainly used in the autoclave of solid material, such as powder material, particle material, etc. If material temperature is too high, also can use steel 籿 kettle bottom of four fluorine ball valve, the ball valve to step down, open the valve material is directly discharged into line, no dead Angle, not like enamel bottom valve shut down after the ball and the space between the bottom bolts will remain material, produce impurities. Large materials will not clog, easy to clean.


And the exhibition valve is mainly used for the discharge of liquid materials, exhibition valve can ensure that the discharge of materials without dead Angle. According to the installation of the autoclave bottom conditions are different, the exhibition valve is divided into up and down, up that is, when the valve core switch, in the valve body internal action; Downward unfolding, that is, the valve core ACTS between the valve body and the tank when it is on and off. When the valve is fully open, the valve core extends into the tank. Upward unfolding ACTS inside the valve body just like ordinary globe valves.
