Use of tank bottom valve

The bottom valve of the tank is used for discharging at the bottom of the reactor, storage tank and other containers. With the help of the bottom flange of the valve, it is welded at the bottom of the storage tank and other containers, so the residual phenomenon of the process medium at the outlet of the container is eliminated. According to the needs of the actual situation, the bottom structure of the ball valve is designed as flat bottom type, and the valve body is V-type, and the valve disc is provided with two working modes of lifting and lowering.

The inner cavity of the valve body is equipped with a scour and corrosion-resistant sealing ring, which can protect the valve body from medium scour and corrosion at the moment of opening the valve, and carry out special treatment on the sealing ring to make the surface hardness reach hrc56 ~ 62, with high wear-resistant and corrosion-resistant functions. According to the requirements, the valve disc seal is overlaid with cemented carbide on the cover, and the seal pair is sealed with wire to ensure the reliability of the seal and prevent the scaling. At the same time, the design of short stroke disc is adopted. It is widely used in chemical, petroleum, metallurgy, pharmaceutical, pesticide, dye, food processing and other industries. Various operation modes, such as manual, pneumatic (spring return, double acting, with and without hand wheel), electric, hydraulic, gear, etc.

Tank bottom valve is a highly clean, sanitary and non retention diaphragm valve installed at the bottom of the container equipment, which is mainly used to vent the materials in the container and not stay in the valve chamber.
