Chainwheel operated closed type goggle valve
Chainwheel operated closed type goggle valve
The closed goggle valve has unique and novel structural design. When opened, it has the characteristics of diversion hole flat gate valve; The sealing surface isn’t affect by medium scouring and coking; During the switching process, the sealing surface is first disengaged to avoid the wear of the sealing surface and greatly reduce the switching operating torque. At the same time, the external sealing structure design makes it completely free of external leakage.
The valve is a reliable isolation equipment in gas medium pipeline. It is suitable for gas, gas and powder transmission pipeline in metallurgy, chemical industry, machinery, energy and municipal engineering systems. The chain wheel type goggle valve manual driving device is mainly used on the manual goggle valve requiring long-distance operation, and is assembled and connected with other parts of the valve through the valve driving device; By pulling the hand zipper strip, the remote manual operation of the valve is realized, so that the use of the valve is more flexible and is not limited by power and air source.
