Chain wheel type dark plate knife gate valve is a new type of gate valve. It is small in size, light…

A gate valve, an overview:

PZL73 series chain wheel dark plate knife type gate valve for flat plate structure, and pipe connected to the clip, the gate is a single gate, and one side of the body seat sealing, back and body side wedge contact between the sealing surface, with the direction of medium relative. The wedge shaped contact structure is in the sealing surface on the back are provided with wedge pressing block, the other side of the valve body is arranged corresponding to the pressing block adjusting screw.

PZL73 series <strong> chain wheel dark plate knife type valve</strong> body structure with short length, light weight, the valve seat sealing surface against medium erosion, sealing surface, uniform compression joint is tight in the closing process, the valve seat sealing surface of the dust and tar scraped away and the sewage is convenient, prevent leakage of medium etc.. Suitable for use in gas containing dust or tar in.

PZL73 series Chain wheel type dark plate knife type valve Is a new variety of valve, small volume, light weight, light material, is an ideal product for sewage, coal slurry, syrup, mud, air, water, slag mixture water, papermaking, mining and other industries. Knife gate valve with the metal to metal seal, or the use of metal to rubber soft seal. In the process of opening and closing the gate, and the sealing surface of the special design, less friction, durable.
Two, Chain wheel type dark plate knife type valve Product features:
1, ultra short length structure saves the material, can make the whole pipeline system greatly reduce weight
