Structural features
1. Optimized design of butterfly plate can effectively increase the flow area of butterfly valve and reduce fluid resistance;
2. Appropriate butterfly plate sealing ring can be selected according
to different working conditions to ensure that the valve will not
produce internal leakage within a maintenance cycle;
3. The valve
body, butterfly plate, pressure ring and other parts are made of carbon
steel material, effectively reducing the manufacturing cost. All parts
in contact with the medium are sprayed with ceramic and other wear
resistant and corrosion resistant coating, which can increase the
resistance to seawater corrosion and erosion of the valve;
4. The
valve axle sleeve is made of duplex stainless steel material, and
interference fit is adopted with the axle hole on the valve body,
effectively preventing the corrosion of seawater on the axle hole of the
valve body;
5. It has a retaining ring between the stem and the
shaft sleeve for the purpose of preventing seawater from penetrating
into the stem and the shaft sleeve and eliminating the corrosion of the
stem and shaft sleeve caused by seawater.
At the same time, it can
prevent sand and mud from seeping into the gap between the valve stem
and the shaft sleeve, causing the phenomenon of the valve stem and the
shaft sleeve to bite, effectively increasing the service life of the
valve;
6. Double-phase stainless steel surfacing on the sealing
surface of the valve seat can be wear-resistant and anti-scouring,
effectively improving the reliability of valve sealing;
7. Adopt
live load combined packing, that is, V-TYPE PTFE+ V-type EPDM packing,
to ensure that the valve does not produce leakage within one maintenance
cycle.
