Q:How big valves are used in a DN159 pipe?
DN159 is the valve with the DN150 in the outer diameter of the pipe.The valve size of the pipeline is classified by nominal diameter:1, the small diameter valve: nominal diameter DN = 40mm valve.2, medium diameter valve: nominal diameter DN from 50 to 300mm valve.3, chase diameter valve: nominal valve DN for 350 ~ 1200mm valve.4, large diameter valve: nominal diameter DN = 1400mm valve.The components of the valve must be handled following process before they are assembled:1, according to processing requirements, some parts need polishing, surface processing burr can not be;2. All parts are degreased;3, after degreasing, pickling and passivation, the cleaning agent does not contain phosphorus;4. After pickling, rinse with pure water, no residue of medicament, and carbon steel parts shall be omitted;5, one by one parts with non-woven fabrics dry, not cable, hair and other retained parts of the surface, or with clean nitrogen drying;6, with non-woven fabrics or precision filter paper, stained with pure alcohol, wipe parts by one, until there is no dirty color.
Q:What does the J41Y-100I valve type mean?
J41Y-100I flange type chrome molybdenum steel valve forgingJ represents the cut-off valve, 4 (flange) on behalf of his connections, 1 (straight) on behalf of his structure, Y (seal) on behalf of his seat sealing surface or liner material code, 100 is the nominal pressure value, I (chrome molybdenum steel) is the code of the body material
Q:Ketem valve relative to other valve companies in the industry what are the advantages?
The electric actuator built-in servo system, no need to add servo amplifier, input 4-20mA signal and 220V AC power supply can control the operation. Compared with the ordinary electric ball valve, the utility model has the advantages of compact structure, small size, light weight, close distance between the valve seat and the end face flange, less material retention, superior sealing performance, etc..
Q:How many kinds of valves are there in the water pipes?
Valve is used as cut-off media, the flow through the fully open, then the pressure medium to run minimal loss. Usually does not require frequent valve for opening and closing, and maintain the gate fully open or fully closed condition. Not suitable for use as a regulator or throttle. For high-speed flow of medium, the gate conditions can cause vibration of the gate in the partial opening, and the vibration may damage gate and valve seat sealing surface, and the throttle gate will suffer erosion media. From the structural form, the main difference is that the sealing elements form. According to the form of seals, often divided into several different types of valve, such as: wedge gate valves parallel gate valve, parallel gate valve, wedge gate valve. The most commonly used form of wedge gate valve and parallel valve
Q:How does the valve close?
Rotate it, turn it clockwise. Spherical valve, then hit a cross shaped on the line.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.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow.
Q:What are the valves at home?
Valve used in the family is commonly used, the following are several:On the water pipe are: total table of the ball valve (32mm), in charge of the (25mm), as well as for the toilet, washbasin, water heater angle valve (20mm).Other commonly used gas pipelines, valves, pressure reducing valves and the like.
Q:Valve and pipe correspondence
Do you mean the form of welding? The size of the valve can be changed according to the size of the pipe!
Q:What does LBC mean in a valve?
Z: gate valve6: connection form for welding1: wedge type single gateY: the sealing surface is cemented carbide800LB: nominal pressure is 800 poundsP: the valve body is made of chrome nickel stainless steel20: nominal diameter is 20 millimetersLB refers to the nominal pressure of the valve, how many pounds, C, P refers to the body material, C refers to carbon steel, and sometimes can be omitted
Q:What items and detailed procedures should be inspected for valve size inspection?
Valve body structure length and flange size, GB size, the implementation of GB/T12221-2005. American Standard. (the American Society of mechanical engineers ASME B 16.10-2000).
Q:Is the heat jacketed valve fitted with flanged flanges?
Insulation valve is the standard valve, just in order to ensure the link bolt flange to super space, usually a large ball than normal level, such as the use of the path is DN80 flange, flange is DN100, so is the standard, but the size of flange connecting with other valves are not the same.
