Pneumatic valve design

in the pipeline system as an important component of the pneumatic valve, shall ensure safe and reliable pipeline system of pneumatic valve manufacturing requirements of the implementation. Therefore, the design of the pneumatic valve must conform to the working fluid pressure, temperature, corrosion, fluid properties and operations, manufacturing, installation, maintenance and other aspects of all the requirements for pneumatic valves.
pneumatic valve design must be based on the clear technical data, 'design input', only the right to complete the design.
'design' type pneumatic valve must possess basic data:
use or pneumatic valve type, medium pressure of work, the work of high media, physical and chemical properties, Toxic, corrosive, flammable, status, etc. ) Length in the table, the nominal by, structure, and pipeline connection, pneumatic valve operation ( Manual, gear drive, worm gear, electric, pneumatic, hydraulic, etc. )
design and construction drawing design technology of pneumatic valves shall be provided data and technical requirements:
, pneumatic valve, flow rate and flow resistance coefficient of pneumatic valve opening and closing speed of opening and closing time, drive the energy feature ( Ac or dc, voltage, air pressure, etc. ) Working environment and conditions, the pneumatic valve, maintenance ( Whether the explosion, a tropical climate conditions, etc. ) , shape or size, weight restrictions, pneumatic valve design process seismic requirements


the design and development planning, design and development stage, each review, verification and validation activities in the design and development, design and develop the responsibility and authority of the

the design and development input, function and performance requirements, statutory and regulatory requirements, information, before a similar design, design and other requirements of the development, must design and development output

and meet the requirements of design and development input, purchasing, production and service provide the appropriate information, contain or reference product acceptance criteria, provide products must be safe and correct use of
the characteristics of product design and development validation method, to confirm the product - the change of the logo on the design and development
