Stainless steel ball valve: the working principle of stainless steel ball valve and its advantages
Stainless steel ball valve has the function of heat preservation and cold preservation. Designed and manufactured according to national standards, petroleum, chemical, metallurgical and pharmaceutical industries are used according to 79-94 standards. Stainless steel ball valve adopts steam jacket insulation. So, the outdoor temperature has dropped to zero degrees a little, the valve operation is flexible, the oil pipe disconnected reliable, no general control valve. The ideal control valve for thick oil pipeline. Customer's needs, the jacket is sandwiched between heat-conducting oil, air conditioning, steam, cooling water, etc., using the entire valve to raise or lower the temperature to the desired temperature, can prevent the media crystallization.
The stainless steel ball valve is a metal jacket welded to the valve body. Steam, heat-conducting oil, cooling water, air conditioning, etc. are injected into the metal jacket to bring the valve body medium to room temperature, heating and cooling conditions. The required temperature is used for insulation or cooling. Stainless steel ball valve is used for high viscosity, steam or other insulators and refrigerants, and cured at room temperature to ensure the normal operation of the medium in the valve.
Working principle of stainless steel ball valve:
Stainless steel ball valve has excellent insulation and cold retention performance, the diameter of the valve is the same as the diameter of the pipeline, very effective in reducing the heat loss of the pipeline cut-off. Has excellent insulation and cold retention performance, can effectively reduce the heat loss of the medium in the pipeline. Stainless steel ball valve is widely used in petroleum, chemical, metallurgical, pharmaceutical and other systems, can well reduce the heat loss of the medium in the pipeline, effectively prevent the medium from solidifying and crystallizing. The role of stainless steel ball valve is that when the temperature is high or low, the material inside the stainless steel ball valve has an adiabatic effect on the medium, so that the medium will not condense or adhere to the valve body, so the valve is normal. It can open and close.
Stainless steel ball valve features:
1. It has a small flow resistance, the resistance coefficient is the same as the same length of pipe.
2. Stainless steel ball valve has the advantages of simple structure, small volume and light weight.
3. At present, stainless steel ball valve sealing surface material has been widely used in plastic, with excellent sealing performance. It is also widely used in vacuum systems.
4. Simple operation, fast switching, from fully open to fully closed only need to rotate 90 degrees °, convenient for remote control.
5. Easy maintenance, ball valve structure is simple, the seal can be moved, easy to disassemble and replace.
6. When the stainless steel ball valve is fully open or fully closed, the ball seat sealing surface of the stainless steel ball valve is isolated from the medium, even if the medium passes through, corrosion of the valve sealing surface will not occur.
7. The diameter ranges from a few millimeters to several meters, with a wide range of applications, from high vacuum to high pressure.

Nationalization is a trend, and there are some localization requirements in some projects. What are your experiences or views on control valve localization? There are actually more localization requirements involved in our work. We require designers to treat imported products and domestic products equally, unless for some special control valve products can not be manufactured in the country recommended the use of foreign brands, generally or domestic brand control valves. For special control valve products, generally in the engineering design, in order to produce a smooth start and operation of the device, the design will generally follow the views of the patent holder to choose a similar device in the use of performance, and in similar devices on the application of good valve products. About localization, now many direct users of the plant, taking into account the convenience of imported valve repair and maintenance, as well as cost factors, will choose some domestic manufacturers to provide inspection and maintenance services for imported valves, but also when the device used in the import control valve problems, in order not to affect production, in the rework waiting process, the use of domestic brand products as an emergency, once the product can cope with this working condition, the use of good Thus also test the reliability of the product, for the future in the same working conditions of the national brand valve application has laid the foundation. Now there are many enterprises that used to do valve maintenance, have accumulated experience in the practical application, the development of the valve production enterprises, to make a contribution to the localization of valves. For domestic valve manufacturers, how to win the trust of the owners is crucial. We now have many projects, are private entrepreneurs to invest in the construction of its cost control requirements are relatively high, the use of localized products in the project also accounts for most. Now many large state-owned enterprises construction projects, have the requirement of localization rate, which also creates a good environment for domestic products to replace imported brands, therefore, domestic enterprises as long as the strengthening of product quality standards requirements, strengthen the internal management of enterprises, continuous technological innovation, to provide good pre-sales and after-sales service, will be able to obtain the trust of the owners, so that the good development of enterprises.
in transport and storage, the gate valve gate and shut-off valve flap should be closed, the plug pathway should be fully open, the check valve flap should be closed and fixed. Both ends of the pathway should be closed firmly. Packaging of various products should be done in transport and storage without damage.
In July 2008, ARC Consulting Group senior analyst Mr. David Clayton (David Clayton) in the "Control Valve Worldwide Outlook" article: based on the rapid growth of the global control valve market in 2006, 2007 two years, forecast the next five years, the global control valve market will maintain a 6% compound annual growth rate. Control valve market will maintain a compound annual growth rate of 6%, based on 2007 global control valve market sales of $4.8 billion, by 2012, the global control valve market is expected to exceed $6.4 billion (Figure below).
Seismic brackets are used for a wide range of applications, including water supply and drainage for engineering buildings, natural heating and central air conditioning, electrical equipment, natural gas, fire safety, etc. Therefore, the engineering and construction regulations for seismic brackets will be more stringent.
