Pneumatic valve pneumatic diaphragm valve in the oil market development prospect

the development of pneumatic diaphragm valve pneumatic valve in the oil market outlook:
pneumatic diaphragm valve in the pneumatic valve market prospect of petroleum and natural gas is quite good, this is closely related with the global emphasis on energy. According to the U. S. Energy Information Administration, the global Energy consumption will increase to a larger index, during the year to year, worldwide would increase %, in this large proportion, the consumption of oil and gas account for more than half of the entire Energy consumption. Oil and gas market, will be a future trend of pneumatic valve.
some question, why not use the new energy to replace the petroleum energy consumption so big? In the next few decades, however, the pattern is not easy to change. Of course to study new energy to replace is the best. But the actual situation of the first, the replacement of energy cannot be realized in a short period of time. So, global oil demand and production remained stable state, in such a favorable macroeconomic conditions, oil and gas of pneumatic valve procurement demand has reached a stable value.
oil pneumatic valve market prospect is good, this has anything to do with pneumatic diaphragm valve and? Pneumatic diaphragm valve is a special kind of truncation type pneumatic valve, is the next five years on the global oil and gas pipeline of a pneumatic valve. Rise to build the pipeline is about. Thousands of kilometers, will be as high as $money, Asia's biggest oil and gas pipeline investment market, this also brings to the pneumatic valve in China regional advantage. Pneumatic valve oil market of oil and gas pipelines in China a lot of investment is also stimulate demand for exports pneumatic valves is an important cause of continued to expand. Pneumatic valve pneumatic diaphragm valve in the oil market development prospect.

synopsis analysis on the advantages and disadvantages and pneumatic diaphragm valve:
pneumatic valve refers to the pneumatic diaphragm valve and pneumatic valve cover is equipped with a flexible membrane or diaphragm, the closing member is connected to the diaphragm of a compression device. Pneumatic valve can Cuo weir shape, also can be straight flow tube wall. Advantages:

(1) operation pathway is separated with the media, not only to ensure the working medium of pure, but also to prevent the pipeline medium impact operating mechanism in the possibility of working parts, pneumatic valve stem place does not need to use any form of single seal, unless in controlling harmful medium for the use of the pneumatic valve and safety facilities;
(2) because the job is only in contact with the medium and pneumatic diaphragm valve body, both can be used in a variety of different materials, so the pneumatic valve to ideal to control a broad range of working medium, especially suitable for medium with chemical corrosion or suspended particles.
3. Simple structure, only by pneumatic valve, diaphragm and pneumatic valve cover assembly of three parts. The pneumatic valve is easy to be fast disassembly and maintenance, replacement of the diaphragm can be done in the field and in a short period of time. Shortcoming is:

(1) due to the aerodynamic body lining process and manufacturing technics of diaphragm and restrictions, large aerodynamic body lining and larger diaphragm manufacturing process is very difficult, so the diaphragm should not be used for large diameter, commonly used in the pipeline under the DN mm or less.
2. Due to limited by diaphragm material, pneumatic diaphragm valve is suitable for the occasion of low pressure and temperature is not high. Is generally not exceed ℃;
(3) regulating performance is relatively poor, only on a small scale adjustment, In commonly close to/when opening, can be used for flow control) 。
