| |
| High temperature high-pressure floodgate valve of the hydropower station |
| Type of the products: Z9(5)61Y |
|
|
Use of the products:
There are two kinds of standard forms in the floodgate valve of the hydropower station, one is introduction type of following ANSIB16.34 and JISL1E101 standard, another kind is according to the national standard type of JB3595 standard. Its temperature followed - the grade of pressure is unanimous, there is a certain exchange relation in some pipelines. Middle part is it have valve overlay pressure urgent type since , have good sealing properties under the high-pressure operating mode in high temperature to adopt. Sealing and enclosing two kinds of materials by oneself, one is low carbon steel, another kind is 316 silks of soft graphite (network ). Seal of upper strata is it get into base hard alloy to weld , pure metal layers of ≥ 3mm behind the processing its, wear-resisting and able to bear the high temperature , anticorrosive and resisting the scotch , having long performance lifing. Prop up both ends of managing in order to weld the structure, weld and can be made according to the standard or user's demand according to the slope mouth. Suitable for thermal power plant , petrochemical industry , metallurgy high-temperature water , metallurgy of high pressure high-temperature water , steam , oil of high pressure , at the overheated pipeline of steam.

Product structure characteristic:
1, there is not a valve that overlay the pressure in the middle part since the urgent type is linked
2, the floodgate board, in order to take wedge type elastic form floodgate board or wedge type a pair of board structure of floodgate
3, the floodgate board / the valve flat piles and welds and bores the base hard alloy two-sidedly
4, resist the high-temperature creep to design
5, the valve stem adopts the nitrogen oozing type and precipitates and hardens the stainless steel
6, there is manual , transmission , electronic of gear wheel (umbrella gear wheel and straight gear wheel ) |
