The structure characteristics and uses:

The valve is closed design structure, the valve body adopts a totally enclosed type shell, but the operating process of gas pipeline leakage, avoiding pollution to environment, has good externalstrength pit piping, electric device is arranged in the external, in order to maintain the check, the people close to operate safety performance is high, the disadvantage is the replacement of rubberring more trouble.

Characteristics of the valve designed to absorb the foreign flashboard valve float valve plate;pressing transmission mechanism adopts the ring gear, gear trapezoidal thread screw pairsynchronous bidirectional pressing. The advantages of ladder shaped screw thread rod aboutsynchronization compaction is: the starting torque is small, the self-locking screw thread pair is good, reliable sealing valve. The valve plate movement of the pin gear transmission mechanism,not easy to accumulate dust, dust more, meet the conditions of poor lubrication, work in harsh environment applications.

Configurable explosion-proof control cabinet of the valve surface, the implementation of on-sitecontrol and remote control system connected with PLC, set the distance is more than 10 meters.
