Very active in foreign markets in recent years, competition is fierce. East and Southeast Asia valve rapid growth of import, market trade between North America and other developed countries of the European Union sustainable development, export to Germany, Italy, Japan, China and other countries and regions to expand imports of US, Britain, France and other countries of high-speed growth, the formation of the international valve market boom anchor Moreover, due to the further internationalization of the world economy, multinational companies will continue to promote the development of the international valve market, international trade area is the completion become another major feature. Environmental valves: domestic environmental protection system, water supply system is mainly required butterfly valve, soft seal gate valve, ball valve, exhaust valve (used to exclude the air pipe). The main sewage treatment system required soft sealing valve, butterfly valve. City gas valves: the city natural gas accounted for 22% of the whole market, the amount of large valves, which type is also more. The main need ball, plug, pressure reducing valve, safety valve. Long pipeline valves: long-distance pipeline is mainly crude oil, refined products and natural pipeline did. The majority of these pipelines required amount of forged steel valves are three-body full bore ball valve, anti-sulfur flat gate valve, safety valve, check valve.
Cyclone works resolutions of the cyclone structure is relatively simple. Ordinary cyclone does not have moving parts, the main component is a barrel of work, to the mine pipe, overflow pipe, overflow pipe and settling mouth. The cyclone is the main working parts work cylinder, which is composed of an upper hollow cylinder and a lower inverted vertebral composition, such a configuration is conducive to flow from spinning. Cyclone itself does not have a power unit, which in conjunction with the use of pumps and other power agencies.
The slurry cyclone disposed of in propulsion power pump, the tangential direction to a certain pressure and flow rate along the working cylinder screwed into the cyclone, then the slurry will be at breakneck speed along the tube wall and produces rotary motion centripetal force, centrifugal sedimentation so that in effect, to complete the slurry parting.
