Wenzhou factory pneumatic discharge valve on the exhibition pneumatic discharge valve ZXDA

Expansion on pneumatic discharge valve Description: 1, use: on-expanding discharge valve is mainly used for the storage tank, the bottom of the reactor and the discharge of materials other containers, valves, flanged or butt weld connected to the device and is located at the bottom eliminate the phenomenon of the process medium residues in the container exports. According to the actual needs into the exhibition style, under the exhibition, piston three kinds of structure; the exhibition formula used with a stirrer reactor discharge; and the next exhibition, piston-type anchor for the frame stirrer reactor discharge. Sealing surface erosion resistant, corrosion-resistant materials, and special treatment, the surface hardness HRC48 ~ 52, with high wear and corrosion resistant features to ensure reliability of the valve seal. Widely used in the chemical, petroleum, metallurgy, pharmaceuticals, dyes, food processing and other industries. 2, features: (1, sealing surface wear and abrasion uniform light, good sealing performance under the Expansion and Development type discharge valve and valve stem is integrally connected, steel and good wear uniform, reliable sealing performance, continuous long life cycle. (2 different opening and closing stroke, installation dimensions of the size Expansion and lower development type discharge valve opening and closing a small stroke, smaller installation height. plunger discharge valve according to the structure and movement of the plunger points the two structural forms lifter and rotating rod, in the form of lift rod structure which requires a larger installation space, but can be based on movement and position of the plunger is visually determine the position of the valve opening and closing and rotating bar structure in the form of mounting height minimum, the opening and closing process only rotational movement of the plunger, it should be based on open and close with the position indicator to determine the opening and closing and the position of the valve. (3, the exhibition opening and closing torque different type discharge valve for the valve up movement valve opens, open the valve when the force required to overcome the media, when you open a relatively close torque next exhibition, piston discharge valve movement valve opens as the valve (plunger) downward, direction and role of media movement open the same force, thereby opening than the closing moments when small. discharge valve consists of a valve body, valve (plunger), stem, packing and driving mechanism and other components, the valve is opening and closing member of the discharge valve Expansion generally disc-shaped or cylindrical, it forms a seal with the valve seat, Vice. discharge valve divide the exhibition formula, under development, piston three types, which is tapered and spherical valve and soft sealing and metal - metal seal and other forms are available.
