Q:What are the production equipment in valve shop?
Machining equipment: CNC, universal car, milling machine, drilling machine (rocker arm drill), wire cutting, grinding machineTest equipment: valve test press according to the production of valve pressure, specifications, types of procurement.
Q:I would like to ask how to access the valve?
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:How to check the quality of the valve?
First, visual inspection of the valve appearance, followed by a spectrometer to check the material, material, and then look at the hydraulic test pressure, whether there is leakage.
Q:What are the technical requirements of valves, such as "Z15W-25T"?
The first Z represents the gate valve;The second bit is omitted, indicating the handle or handwheel;Third bit 1, indicating internal thread connection;Fourth bit 5, indicating dark wedge rigid single gate;Fifth W, which means the sealing materials are the main body material of the valve;The second paragraphThe first 25, said the nominal pressure is 2.5MPa (valve used in accordance with the pressure level of GB/ 1048, the use of GB/T 1048 standard 10 times the unit of MPa (MPa) value, otherwise the unit value is MPa. If it is a power station valve, the unit value is MPa.)Second bit T indicating copper and copper alloy for the valve body.
Q:Ketem valve relative to other valve companies in the industry what are the advantages?
Floating seal: electric drive, electric ball valve flange connection floating ball straight, seal form with seal, the sealing surface of the valve seat material for hard alloy, nominal pressure PN16~PN63, nominal size DN15~DN200, suitable temperature of -28~500, the valve body is made of carbon steel or stainless steel. As a result of the use of hard sealing (metal seal), this valve is particularly suitable for particles, solids, slurry and other medium and high temperature and high pressure pipelines.
Q:Valve connections - two how do different connections work?
The connection of two different connection forms is achieved by a transition conversion connector
Q:How to identify a good or bad valve?
You can see what the material inside the valve ~ basically copper heart relatively durable, solid ~!
Q:Suddenly no water at home, asked about the property,
That's a lie. Other people's homes do not necessarily have water.You need to keep on pressing the property.
Q:How are the types of valves classified?
Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.classificationFunction and use(1) cut off categories: such as gate valve, globe valve, plug valve, ball valve, butterfly valve, needle valve, diaphragm valve and so on. Cut off valve, also known as closed-circuit valve, stop valve, whose role is to connect or cut off the pipeline medium.Check valves, also known as check valves or non-return valves, check valves belong to an automatic valve, its role is to prevent the pipeline medium backflow, to prevent the pump and drive motor reversal, as well as the leakage of container media. Pump water off the bottom valve check valve also belongs to class.The function of the relief valve is to prevent the medium pressure in the pipeline or device from exceeding the required value so as to achieve the purpose of safety protection.Control valve, throttle valve and pressure reducing valve, its role is to regulate the media pressure, flow and other parameters.(2) vacuum type: such as vacuum ball valve, vacuum flapper valve, vacuum air charging valve, pneumatic vacuum valve, etc.. Its function is to change the direction of the air flow in the vacuum system, adjust the air flow rate, cut off or connect the vacuum system of the pipeline, and the component is called the vacuum valve.(3) special uses such as pigging valves, vent valves, drain valves, exhaust valves, filters, etc.. The exhaust valve is an essential auxiliary component in the pipeline system. It is widely used in boilers, air conditioners, petroleum, natural gas, water supply and drainage pipelines. Often installed in the commanding heights or elbows, etc., to exclude excess gas pipeline, pipe road to improve the use of efficiency and reduce energy consumption.
Q:What are the other valves used for the control of dual-use items?
The coding needs to do export dual-use items technical license, this is to go to Beijing for approval for 1 months, I have the electronic key for you to handle, you can also charge electronic keys
