Description of pneumatic on expanding discharge valve:

1. Uses: the main storage type discharge valve is mainly used in the storage tank, the reaction kettle and other containers of the bottom discharge material, the valve uses a flange or butt welding and equipment connected to the bottom, eliminating the process media usually in the container export residue phenomenon. For the expansion, expansion, plunger type three structure according to the actual needs of the situation; the expansion for reactor with stirrer discharge; and expansion, plunger type reactor for frame type anchor agitator discharge. The sealing surface is made of corrosion resistant material and special treatment, so that the surface hardness can reach HRC48 ~ 52, which has the function of high wear resistance and corrosion resistance. Widely used in chemical, petroleum, metallurgy, pharmaceutical, dyes, food processing and other industries.

2, features:

(1, sealing surface wear uniform and less abrasion, sealing performance good on the show and the next show type discharge valve and valve stem for the overall connection, good wear uniform steel, sealing performance is reliable, continuous use of a long cycle.

(2, opening and closing the trip is different, the installation size has the size of the upper and lower development type discharge valve opening and closing of the valve opening and closing, the installation height is small. Plunger type discharge valve according to the plunger structure and motion mode is divided into two kinds of structural form of the lift rod and the rotary lever. The structure of the rotary rod is installed in the form of a minimum, and the piston is only a rotary motion in the process of opening and closing.

(3, opening and closing torque on different type of release valve for the valve to open the valve to the valve to open the valve to overcome the media force, the more closed when the torque. Under development, Zhu Sai type discharge valve for the valve flap valve (Zhu Sai) down the valve to open, the movement direction and the same force acting on the same time, thus opening the more closed torque.

Discharge valve mainly by the valve body, valve valve (Zhu Sai), stem, sealing filler and the drive mechanism, the valve is on the open and close the valve opening and closing parts, generally a disc shaped or cylindrical, it is sealed with the valve seat. The discharge valve on the expansion and expansion, plunger type three types, the valve is conical and spherical and soft seal and metal to metal seal and other forms are available.

Item: may choose the following attachments according to different control and requirements:

Return message: also called limit switch, remote feedback switch signal (optional explosion-proof).

Solenoid valve: dual role of the five two, a single role in the election of three two (optional explosion-proof).

Three parts: the gas supply regulator, filter, cylinder and lubricating oil.

Hand wheel mechanism: rotating hand wheel mechanism can be achieved manually open and close valve.

Electrical locator: input 4 ~ 20mA signal, to achieve the valve adjustment function.

Order form:
