API standard low-temperature steel globe valve is a valve designed specifically for low-temperature environments, with the following characteristics and product introduction:
1. * * Low temperature resistance * *: American standard low-temperature steel globe valves can maintain the strength and sealing performance of pressure bearing components at ambient temperatures ranging from -50 ℃ to -196 ℃.
2. * * Working principle * *: By relying on the pressure of the valve stem, the sealing surface of the valve disc is tightly adhered to the sealing surface of the valve seat, preventing the flow of the medium. It belongs to a forced sealing valve.
3. * * Medium flow direction * *: There are two flow directions: "low in, high out" and "high in, low out". Only one-way flow of the medium is allowed, and there is directionality during installation.
4. * * Structural Features * *: Simple structure, easy manufacturing and maintenance, small working stroke, short opening and closing time, very suitable for use as cutting or adjusting and throttling.
5. * * Material combination * *: The materials of the main body, internal components, fillers, gaskets, and fasteners can be reasonably combined according to user requirements or actual working conditions.
6. * * Design and Manufacturing Standards * *: Design and manufacture according to API 623, GB/T24925, inspection and testing according to API 598, flange connection according to ASME B16.5, butt welding end: ASME B16.25, socket welding end: ASME B16.11, structural length: ASME B16.10, temperature and pressure rating: ASME B16.34.
7. Valve Cover Design: The valve cover is designed with a long neck structure, which can isolate the influence of low-temperature media on the packing, prevent the performance of the valve cover seal from decreasing, and make the valve open and close flexibly.
8. Design of opening and closing components (valve disc): Conical sealing valve disc is usually used, and flat sealing valve disc can be used according to customer requirements and actual working conditions. The sealing surface can be welded with gold material or embedded with non-metallic material according to user requirements.
9. * * Gasket form * *: Class150~Class300 globe valves use stainless steel graphite wrapped gaskets; Class600 globe valves can use stainless steel graphite wrapped gaskets or metal ring gaskets, while Class900~Class2500 globe valves use self sealing metal rings.
10. * * Technical parameters * *: nominal pressure 150LB-900LB, applicable temperature -196 ° C -+80 ° C, applicable media include liquid oxygen, liquid nitrogen, liquid argon, liquefied natural gas, liquid carbon dioxide, etc.
11. * * Product Application * *: Widely used in chemical plants such as LNG, liquefied natural gas transport ships, air separation equipment, petroleum and chemical tail gas separation equipment, liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide low-temperature storage tanks and tank trucks, pressure swing adsorption oxygen production, etc.
