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:Several problems about valve parameters
FV or LV on the flow chart, which represents the instrument bit number, FV is flow valve, and LV is level valve.The valve on the nameplate CV value, it is a measure of the size of the valve flow, it is the concept of 40 - 60 degrees Fahrenheit in the water, the pressure drop of 1 psi, in a valve opening per minute flow through the valve (U.S. gallons).
Q:What are the technical requirements of valves, such as "Z15W-25T"?
Threaded copper gate valve. Z15W-25T is a valve type, wherein each byte has a specific meaning, see detailed People's Republic of China machinery industry standard JB/T 308 "valve model establishment method", "JB/T" model establishment of power station valveValve 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.Model refers to the product performance, specifications, sizes, materials and other indicators of the set of code.
Q:Which valves are installed in a directional manner?
There are balance valve, safety valve, pressure relief valve
Q:What's the valve specification DN20?
Valve specification DN20 is 6.The inches in the valve refer to inches, 1 inches =25.4mm, and 1 inches =7.62 cents.The corresponding relation between inch and DN and mm is:4 is divided into corresponding caliber DN15, that is, diameter 15mm;6 is divided into corresponding caliber DN20, that is, diameter 20mm;1 inches for the corresponding caliber DN25, that is, diameter 25mm;1.2 inches for the corresponding caliber DN32, that is, diameter 32mm;1.5 inches for the corresponding caliber DN40, that is, diameter 40mm;2 inches for the corresponding caliber DN50, that is, diameter 50mm;2.5 inches for the corresponding caliber DN65, that is, diameter 65mm;3 inches for the corresponding caliber DN80, that is, diameter 80mm;4 inches for the corresponding caliber DN100, that is, diameter 100mm;5 inches for the corresponding caliber DN125, that is, diameter 125mm;6 inches for the corresponding caliber DN150, that is, diameter 150mm;8 inches for the corresponding caliber DN200, that is, diameter 200mm;10 inches for the corresponding caliber DN250, that is, diameter 250mm.
Q:What do you mean by the 16 bit coding of the valve type?
Valve model is by the type of valve, valve drive, valve connection, valve structure, sealing material, valve body material code to indicate.1. Valve types are Z- gate valve, P- drain valve, Q- ball valve, D- butterfly valve, J- stop valve, etc.;2, the valve drive mode code by letters said, common 2- electric hydraulic, 9- electric, 6- pneumatic, 5- bevel gear drive, 3- turbo worm; manual do not need to write out3, the valve connection form code with letters to indicate, 1- internal thread, 2- external thread, 4- flange type, 6- welding, 7- pairs clamp type, 9- clamp, 0- card sleeve;4, valve structure code, for example: 0- 1- flexible gate valve, open bar wedge type single gate, 2- rising stem wedge gate, 3- parallel single gate, 4- double disk parallel, 5- dark pole single wedge gate, 6- dark bar wedge gate, dark 7- parallel single gate, 9- dark pole parallel gate;5, sealing materials or lining materials were used R- T- austenitic stainless steel, copper alloy, X- rubber, S- plastic, N- nylon, F- fluorine plastic, H-Cr series stainless steel, hard alloy Y-, J- rubber lining, Monel M-;6, the body material code Z- K- gray cast iron, malleable cast iron, Q- ductile iron, copper and T- alloy, C- steel, P- chromium nickel stainless steel, R- stainless steel chromium nickel molybdenum, chromium molybdenum vanadium steel V-.For example: electric, flanged, rod wedge gate valve, sealing surface material by direct processing, nominal pressure PN0.1MPa of the valve body is made of grey cast iron gate valve: Z942W-1 electric wedge gate valve.
Q:High and low pressure valve is how to distinguish?
Vacuum valve - valve with operating pressure below standard atmospheric pressure.Low pressure valve - nominal pressure PN is less than 1.6MPa valve.Medium pressure valve - nominal pressure PN 2.5~6.4MPa valve.High pressure valve - nominal pressure PN10.0~80.0MPa valve.Ultra high pressure valve - nominal pressure PN greater than 100MPa valve.
Q:What does the torque of the valve mean?
Unit: Newton M. torque is the minimum torque used to turn on the valve. It is the force that opens the valve!The valve that indicates the opening of the PZ73X-10C DN50 requires 5 meters of force.
Q:What does valve A335P22 mean?
The first seems to refer to the material inside the valve, containing Cr of 13% (equivalent to the 1Cr13 of our country), FHF=full face hardThe other refers to the body of the material, the corresponding standard forWC6=ASTM A217 WC6P280GH=EN10222 P280GHA335P22=ASTM A335 P22
Q:How to better maintain the valve?
Use and maintenanceThe maintenance of the aim is to extend valve life and ensure reliable opening and closingThe stem threads, often with the stem nut friction, to a little yellow dry coating oil, molybdenum disulfide or graphite, lubricationWe do not often open and close the valve, but also on a regular basis handwheel on the stem threads to add lubricant to prevent bitingThe outdoor valve, to increase the protection sleeve on the stem, to rain, snow, dust and rustIf the mechanical valve system to be fixed, to add time to the gearbox oil
