The valve installed under the enamel reactor has many common terms, some people call it enamel reactor valve, some people call it tank bottom valve. This valve is mainly used for the function of enamel reactor below the discharge, so we often use the name is the discharge valve.
There are several kinds of discharge valves, common on the extended discharge valve, extended discharge valve, flat-bottomed discharge valve, ball discharge valve (discharge ball valve) , cylindrical discharge valve and long cylinder discharge valve, these discharge valves are also known as tank bottom valves or reactor valves. Enamel reactor in the choice of valve use, according to the working conditions of the selection of the corresponding discharge valve. If there is corrosive medium, must choose stainless steel or ceramic exhaust valve, but there is no corrosive medium, you can choose carbon steel, cost savings. For 45 degree angle discharge, should choose up-spread discharge valve or down-spread discharge valve and flat-bottom discharge valve. Optional ball-type discharge valves that require vertical discharge or quick opening of materials are also known as discharge ball valves.
Usually the enamel reactor medium is viscous, granular or powder, and some media with solidification. If the material solidifies within a certain time after the stop of the reaction, in this case we should select an upward-diffusing discharge valve. Discharge valve is mainly used for reflector, storage tanks and other containers, can not be used for other aspects.
The discharge valve is simple in operation and convenient in use. Angle discharge valve switch is a rotary switch, only hand wheel rotation to switch, and discharge ball valve rotation 90 degrees to open, faster operation, but only vertical discharge. The plunger drain valve is similar to the inclined outlet structure of the plunger valve. The disc ensures the free opening and closing of the valve, and better guarantees the anti-clogging performance and sealing performance. The lift type discharge valve is directly installed at the bottom of the tank (enamel reactor) under the valve. After welding the flange under the tank, the valve is mounted on the flange.
In the alumina industry, upstream discharge valves are usually selected. In terms of maintenance, need to check whether the pipeline corrosion, Booty, dust, etc. . And clean it up. When the valve in the use of the process can not meet the requirements, should be timely inspection, repair or replacement. Lubricate the stem frequently. An assembly seal is arranged outside the discharge port. Because the ball drain valve is installed vertically, it is very convenient to operate and install. In addition, if wear-resistant requirements, temperature should be selected enamel reactor exhaust valve, wear-resistant.
