Product description
Products are mainly used in
turbine extraction pipelines, blast furnace gas pressure generating
device into the gas pipeline and other high-level safety control system
for urgent emergency off valve: in the system crisis conditions or
accidents, in 0.3-0.5 Seconds to try an emergency off the moment the
valve to achieve a reliable medium for the pipeline to effectively
prevent the steam turbine tail steam and condensate back or cut off the
gas pipeline to protect the safety turbine unit. The introduction of
this product to introduce advanced foreign fast shut-off valve function,
and technical optimization and improvement, additional buffer device to
avoid inertial impact, product performance more reliable, and extend
the service life of the valve.
Features
1, using the optimized three-dimensional structure of the eccentric
metal seal, high temperature anti-jamming, open and close easily and
completely avoid the traditional metal seal contacting the valve
abrasion ills;
2, reliable sealing, zero leakage seal test;
3, direct Rack and pinion piston drive, compact structure, 3 ° closed
buffer design, constant torque opening and closing, reliable action;
4, integral or split electro-hydraulic control device, easy installation.
