Q: What does the PN on the valve mean?: 1, mark "ON25" and "PN16" respectively what does that mean? 2, the valve above has an outer six corners, so PN16 refers to the nominal pressure of 16 kg valve. Valves on the fittings are standard parts, special

Q: 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: 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.

Q: I would like to ask this valve (not too clear, is it possible to call the valve), what is the specific name of the professional? Where can I buy it?: From the appearance of it is not too good to say, if it is the valve, only one-way valve.The valve usually consists of the stem, spool, seat, body, seal, and so on. This figure feels more like a filter that connects a pressure vessel to an inlet or an inlet.I've seen a lot of filters like this, usually open with -drain filter inside. Play a role in the filter of some large magazines, you can change, more metal, the mother is relatively small (relatively large hole)

Q: The difference between fire general valve and fire fighting special valve: Fire fighting valves are mainly signal valves and alarm valves and water indicators, etc., other gate valves, butterfly valves, pressure relief valves and filters are common valves.

Q: the valve to an electrical signal, with this signal to control other components, ask: what valve?: Online search "air switch", many suppliers.You may choose your pipe according to your pipe diameter.The flow meter can also be used to control the flow of operation

Q: What is called protective valve, and other valves what is the difference?: Protection valve should be in the air defense valve, can be copper gate valve. (according to the specific use of civil air defense requirements, design institute does not count).2, while the protection valve should be a locking device with the valve, not the general valve can be replaced.

Q: What does valve DN50/80 mean?: Hello landlord DN50 valve refers to the valve diameter of 50mm DN80 is 80mm if the valve is opening and closing function, so the valve diameter should be and pipeline with the diameter or smaller number, large waste, butterfly valve to be stuck in the flange, the influence of flow.If the role of the valve is adjusted, and that caliber will be different from the pipe diameter, this is not to reduce the cost of the problem, is a result of calculation, and this calculation results with flow, pressure drop and valve resistance curve.For example, control valve, usually smaller than the pipe diameter, such as pressure reducing valve, will be smaller than the pipe diameter to two, such as 57mm pipe with DN50.

Q: Can the angle valve of York central air conditioner be replaced by other valves?: Definitely. But I want you to tell me what you're doing, or give me a picture. I can give you some advice
