First, description of products:
Second, the products are summed up:
It can be on the foundation of foreign advanced technology to
introduce, adopt the accurate J elasticity to seal enclosing and
hard sealed structure of three partial multi-level metal, used in
medium temperature ≤manage the gold , electricity , petrochemical
industry , and give draining off water and urban construction etc.
on the industry pipelining of 425 degrees Centigrade extensively,
make the flow of regulating and break fluid use in year. This valve
adopts three partial structure, valve Tower and disc board seal the
surface and adopt different hardness and stainless steel to make ,
there is the good one that is able to bear corrosivity , have long
performance life, this valve of two-way sealed functions of field
mail, the products accord with the experimental standard of
national GB/T13927-92 valve pressure.
Third, products characteristic:
1, this valve adopts three partial sealed structure, valve seat and
butterfly's board have not almost been worn and torn, cross the
sealed function with the more urgent view.
2, seal and enclose and select the stainless steel for use to make,
have metal hard sealing and double advantage with sealed elasticity
, no matter in a situation that it is low and gentle and
high-temperature , have a fine sealing property ,
corrosion-resistant, characteristic of having long performance life
etc..
3, the disc board seals the surface and adopts and piles and welds
the cobalt base hard alloy, seal the surface to decrease
wear-resisting , have long performance life.
4, butterfly's board of the heavy specification adopts Hang's shelf
structure, the intensity is high, is it flow area to be heavy to
pass, is it hinder little to shed.
5, valve this have two-way sealed function, when installing the
restriction that the medium flow into, free of the space position
too , can install in any direction .
6, the drive can be installed in many worker's location (rotates
90° or 180°), benefit user's use.
