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:How do I open the gas valve?
First of all, you have to determine the direction of the valve opening, usually homeopathy, it is off, the reverse is open. First: to determine the opening of the valve, are generally ball valve, screw 90 degrees on it. Second. At the top of your house, there is a button that can be pulled out. It's different from place to place. Some are pulled out half, and some are pulled out.
Q:How do you see the valve number?
The meaning of valve number:Valve type Z, J, L, Q, D, G, X, H, A, Y and S respectively: gate valve, globe valve, throttle valve, ball valve, butterfly valve, diaphragm valve, plug valve, check valve, safety valve, relief valve, drain valve.The connecting codes for valves are 1, 2, 4, 6, 7, respectively: internal thread, 2, outer thread, 4, flange, 6, welding, 7, pair.Valve transmission mode code 9, 6, 3, respectively, said: 9, electric, 6, pneumatic, 3, turbo worm.Body material Z, K, code Q, T, C, P, R and V respectively: grey cast iron, malleable cast iron, ductile iron, copper and alloy, carbon steel, stainless steel, chrome nickel chromium nickel molybdenum stainless steel, chromium molybdenum vanadium steel.Seat sealing or lining R, T, X code, S, N, F, H, Y, J, M, W respectively: austenitic stainless steel, copper alloy, plastic, rubber, nylon plastics, fluorine plastic, Cr stainless steel, hard alloy, rubber lining, Monel alloy, valve body material.
Q:How do you calculate the flow of the valve?
Valve flow calculation value is very vague, pipe pressure, back pressure, medium viscosity, medium temperature, valve structure, and so on, will affect the calculated value.
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 do you calculate the valve wall thickness, pressure, and other valve design calculations in a spreadsheet?
Which standard does the wall thickness refer to? ASME B16.34?Design and calculation depends on what standard you chooseOr have you found the standard yourself and read it yourself?You choose what standards, design parameters reference, interpolation or fitting, how to fit, are their own sayI wrote a excel series of valve calculations, it does not take long to writeFor long-term useIn order to improve efficiencyOr write your own database program is better
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 valve should be used to test the water valve?
1, ball valve.2, the water test valve can be ball valve, gate valve, stop valve, installed in the fire sprinkler system at each level of the end of the pipe.
Q:Who knows what the DE stands for in the valve DE50?
Back valve, DE50 balance valve, DE25 stop valve, DE75, what do you mean by "de"?Diameter DEThe diameter of a general plastic tube is indicated by DE in EngineeringNominal diameter is the size of all piping accessories in the piping system. The nominal diameter is a convenient round integer for reference and is not strictly related to the processing size. The nominal diameter follows the letter "DN" followed by a number sign.
Q:G what's the meaning of the valve?
G is the diaphragm valve, valve type code, there are other types of valve code.A D is a safety valve, butterfly valve, check valve (H valve), J is the cut-off valve, throttle valve is L, P is Q is the drain valve, ball valve, S trap, U X is a plunger valve, plug valve, Y valve, Z valve.
