Desulfurization butterfly valve Applications:
It
can be widely used in regulating and intercepting flow lines in
hydropower, sewage, construction, air conditioning, petroleum, chemical,
food, medicine, textile, paper making and water supply and drainage.
Gas, oil and other media, suitable temperature -20 ~ 80 ℃. By replacing
the valve plate seals, O-rings, disc, shaft and other materials,
applicable to a variety of media and different temperatures. Automatic
valve control equipped with high-quality electric actuators or
double-acting pneumatic actuators, automatic and manual dual opening and
closing functions can be achieved.
Desulfurization butterfly valve structure features:
The main structure is composed of valve body, valve disc, valve seat, valve stem and transmission operation mechanism and other components. The valve seat adopts detachable structure, and according to the physical and chemical characteristics of different media, the corresponding high temperature resistance, low temperature resistance, corrosion resistance , Light, anti-aging materials.
Valve ductile iron shell inside and outside the surface can be high temperature electrostatic spraying epoxy powder coating, the coating has high corrosion resistance, and ductile iron matrix has a very high bonding strength, coating degree of 0.2-0.5mm.
1, the use of neutral structure without eccentric
design, with significant characteristics of low operating torque,
electric device configuration when the economy is significant;
2, a reasonable design, compact structure, easy installation and removal, easy maintenance;
3, , Butterfly plate circumferential sealing surface precision
machining to a higher finish, the friction coefficient of the rubber
valve seat is very low, longer valve life;
4, valve plate sealing surface flow characteristics of a linear state,
with a smaller flow resistance Coefficient, valve flow resistance is
small;
5, a unique design of the molded rubber valve seat has excellent
balance and support, effectively avoid the force caused by the rubber
damage, the valve at the fully closed position, the rubber in the best
to maintain the compressed state zero leakage;
6, the two-port valve sealing surface projecting rubber flange ductile
iron, no additional valve rubber gasket installed in the pipe
7, the valve operating mechanism flexible choice;
8, valve attractive appearance resistance Corrosive.
