I would like to ask how the valve entry, for a new pair, really difficult, what cutaway view, there are other, just contact the valve less than a week, and sometimes it is really difficult to understand. Forget the experienced teacher can be generous with your criticism to later, indebted forever, learn the valve Comrades some help.In a company CAD to relatives as soon as possible to a company, and then slowly improve, I do not know what is the request of the novice, and how to start as soon as possible, I am learning routine is: give me a set of valve design drawings, and then I paint it on, do not understand the structure and workshop look. I wonder if you have any good learning methods that can be referred to and supplemented by younger brother
Valve range can be very wide, each company to do valve products are not the same;According to the company's production capacity and technology,Valve parameters to:1, valve spool material,2, connection mode (thread, welding, flange, clamp, socket welding, fast loading, etc.),3 caliber,4, medium (water, steam, oil, gas, liquid, etc.),5, temperature (medium temperature, environmental temperature),6, pressure (MPa, LB, K, etc.),7, configuration (executor and its accessories);A lot of valve requirements and this almost. Can also be selected according to the ideal valve function of customers.Switching type:Ball valve, butterfly valve, globe valve, gate valve, needle valve, etc.Regulatory type:Pneumatic valve, electric valve (adjustable type can be divided into: regulating temperature, regulating pressure, regulating flow), and so on
May learn some basic knowledge of valves, learning in practice, relatively fast.
I was about 08 years of contact valve, indeed many, but a company, all products will not have, are designed to do certain types of valves, such as for HVAC, or petrochemical, some other valves used in engineering, will do the purchase, so you only according to the company's products study on the line, need to learn what, what, high efficiency.If you do the design, you have to learn a lot of things: "mechanical design manual" and "valve design manual" is essential, often used;Of course, functional things are the basis, that is, the structure, the work principle must be obtained first, in order to do relevant design and improvement;First of all, the structure design, CAD must learn, three-dimensional software also have to learn one, Solidworks, Peo/E, UG, Catia can be;Second, strength analysis is necessary, so in mathematics, mechanics, mechanical design things to learn solid; can make strength analysis with finite element analysis software, need to learn, software Comosworks, Ansys;Third, the valve design will have fluid aspects, flow design, flow capacity, flow characteristics of the study, to study fluid mechanics, heat transfer, etc., CFD software has Fluent, Ansys, CFX, Star-CD;In addition, materials and technical aspects should be learned.Slowly, I also step by step by side with coming.Hope to be of help to you.
