Structural Characteristics of Welded Bellows Globe Valves and Standards for Welded Ports
The welded bellows shutoff valve is suitable for pipelines in various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, and power industries, and cuts off or connects the pipeline medium.
Welded bellows globe valve product structure main features:
1, the product structure is reasonable, reliable sealing, excellent performance, beautiful appearance;
2. Cobalt-based hardfacing alloy on the sealing surface, wear resistance, corrosion resistance, anti-friction performance, and long service life;
3, rod quenching and surface nitriding treatment, have good anti-corrosion and anti-friction performance;
4, double seal, more reliable performance;
5, the valve stem lifting position indication, more intuitive;
6. The size of parts, flanges and butt welds can be reasonably selected according to the actual working conditions or user requirements to meet various engineering needs.

The cutting machine is suitable for the cutting of Chinese medicinal herbs including rhizomes,fruitages,leaves,and grasses etc before it being fine processed,grinded or extracted,as well as for the cutting process of foodstuff(sliced fruit,preserved fruit),aquatic products(sliced kelp),tobacco leaves,and tea leave etc.This slicing machine is composed of motor, variable speed mechanism, tool rest, step and retreat material, adjustable tool rest machinery and so on. Due to the use of advanced step feeding, so that the cut of the sheet shape uniform, can freely control the feeding distance, will not cause the material extrusion knife bad situation. Due to the reasonable layout, the machine is easy to operate, light appearance, light weight. This machine is mainly composed of two parts, such as conveying and cutting medicine, machinery and so on.
