Boiler steam globe stop valve structure:
1. Boiler steam globe stop valve adopts straight through structure.
2. In order to avoid in the process of use, the media on the sealing pair of high speed scouring, sealing with double seat structure, the first throttling and blocking debris, in the use of throttling after the medium to make the sealing surface self-cleaning, so as to completely solve the valve closed, due to the dirty medium pressure on the seat sealing surface, so that the valve leakage and short service life.
3. The connection between the boiler steam globe stop valve body and the cover of the  steam valve with nominal diameter DN≤50mm is a clamp pin shaft connection, and the connection between the valve body and the cover of the high pressure steam valve with DN65 and above is a self-sealing flange connection form. These two structures are convenient to disassemble and install, safe and reliable.
4. The branch pipe at both ends of the valve is welded.
5. Boiler steam globe stop valve seat and disc sealing surface are made of imported cobalt-based hard alloy surfacing. The sealing surface has the characteristics of high hardness, abrasion resistance and abrasion resistance.
6,.The nitrogenous steel as the Boiler steam globe stop valve stem material, so that the nitrogenous valve stem surface hardness is high, wear resistance, abrasion resistance, corrosion resistance, long service life.
