Ball Valve From Raw Materials
Oct 30, 2017
Ball valve is the most widely used, the ball valve it has a rotation of 90 degrees of action, the plug body for the ball, a circular through hole or channel through its axis. Ball valve in the pipeline is mainly used to intercept, distribution and change the direction of the media, it only needs to rotate 90 degrees of operation and a small rolling torque can be closed tight. Ball valve is most suitable for switching, plugging valve use.
Ball valve from the raw material can be divided into: carbon steel ball valve, stainless steel 304 ball valve, 316 ball valve and copper ball valve and cast iron ball valve. Widely used in petroleum, chemical, power and other departments, is made of stainless steel as raw materials, stainless steel ball valve products with strong anti-corrosion characteristics, simple structure, tight and reliable features.
Ball valve seven advantages
1, the fluid resistance is small, the resistance coefficient and the same length of the pipe section flat;
2, simple structure, small size, and light weight;
3, tight and reliable, and now the ball valve sealing surface information widely used plastic, good sealing, in the vacuum system has also been widely used;
4, easy to operate, open and close, from full open to full clearance only need to rotate 90 °, easy to remote control;
5, easy to repair, ball valve structure is simple, the seals are usually active, open replacement are more convenient;
6, in full or closed, the ball and the seat of the sealing surface and the media isolation, the media through the period, will not lead to the erosion of the valve sealing surface;
7, ball valve for a wide range of small diameter from a few millimeters, large to 1.2 meters, from high vacuum to high pressure can be applied.
With the needs of modern life, then the production of these important products, spare parts are endless. Here we list the main application areas of these 10 categories of valves.
1) oil refineries, oil refueling devices need to use valves are mostly pipeline valves, mainly for the gate valve, check valve, check valve, safety valve, ball valve, butterfly valve, trap, which, the valve demand accounted for about 80% of the total number of valves, (Valves account for 3% to 5% of total investment).
2) chemical fiber device, chemical fiber products are polyester, acrylic, vinylon three categories. Its need to use the valve ball valve, jacket valve (jacket ball valve, jacket valve, jacket cut valve).
3) acryl clear device. The valve is generally used in the scale of the valve, mainly for the gate valve, globe valve, check valve, ball valve, trap, needle valve, plug valve, which accounted for about 75% of the total valve.
4) ammonia plant. Because the synthesis of ammonia and purification methods are different, the process is different, the required technical function of the valve is also different. At present, the domestic ammonia plant mainly need gate valve, globe valve, check valve, trap, butterfly valve, ball valve, diaphragm valve, regulating valve, needle valve, safety valve, high temperature and low temperature valve.
