Q:Proportional valve why than other small pipeline valves
3.7 machinesGraphical representation of numbers, names, symbols3.7.1 motors include synchronous or asynchronous and micro AC and DC motors3.7.2 generator3.7.3 centrifugal liquid pump, liquid from open end, closed end3.7.4 piston pump liquid from the open end, closed end3.7.5 pump water from the mouth into the mouth closed3.7.6 vacuum pump gas from the open end, closed endThe 3.7.7 screw and the small end of the turbo compressor represent compressed gasThe small end of the 3.7.8 piston compressor represents compressed gasThe small end of the 3.7.9 membrane compressor represents compressed gas3.7.10 turbine low pressure gas expansion after the big endian representation3.7.11 said the main piston expander after expansion of low pressure gas3.7.12 turbo expander small end said high-pressure low end big endian representation3.7.13 motor brake expander small end said high-pressure low end big endian representationThe heat exchanger or Freon evaporator for 3.7.14 water and freon refrigeration unit
Q:What is the difference between valve j941H-40 and j41H-40?
The difference is that one drive is electric, one is transmission, and the other is manual."Valve design manual" showsJ- stop valve9- electric4- connection means flange connection1- through typeH- sealing surface is alloy40- operating pressure is 4.0Mpa (or 40 kg)More than one, 9, 9 fingers, electric, more than an electric.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. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
Q:Valve installation
It looks a bit like the butt weld butterfly valve. The two sides are welded to the pipe. There is a step on either side of the valve. Overhead welding
Q:What valve is the DN 25?
DN25 is just a caliber, a variety of valves, depending on your actual needs to buy Valves, water or gas, or other special functions, are the basis for the purchase of the valve must be provided
Q:How to find all kinds of mysterious valves of human body?
Many cell signal channels have been found, and if you can find each signal, the channel will be almost the same. That's the mysterious valve you want, but it's hard.
Q:How do you calculate the pressure difference between the front and rear of the valve?
Well, it's not easy. And you do not give the specific structure of the valve, so there is no way to talk about the calculation. The simplest way is to install the pressure gauge and the flow meter on both ends of the valve, and read the data directly.
Q:What items and detailed procedures should be inspected for valve size inspection?
Internet access can be downloaded, such as free standards to share and download sites. If you need any other valve standard, send me the mailbox.
Q:What is the normal temperature on the valve?
3. classification by operating temperature(1): ultra-low temperature valve for medium temperature of t< DEG C; 101 valve.(2): used for medium temperature valve operating temperature 101 C = t = 29 C valve.(3) at room temperature for medium temperature valve: the valve 29 425 degrees celsius.If it helps, see it
Q:Symbols for all types of valves
Look at the attachment I gave you. The legend of the valves is complete!
Q:What is the difference between low pressure valves and medium pressure valves and high pressure valves?
In fact, this is only the valve industry sector argument, not necessarily to distinguish between very clear.As long as the customer pressure requirements, we give him the drawings on it.Valve flange thickness and valve thickness are not standardized, according to pressure requirements.The flange thickness of 6.4Mpa and 10Mpa is completely different from that of valve body.For example: general gate valve, the most basic pressure 1.6MPa, according to GB/T139272008 and JB/T90921999 standard castingGenerally selected 1.6MPa, when the highest pressure pressure is 1.6X1.5=2.4MPa, if you exceed this pipeline pressure is not, there are now many manufacturers in order to save costs, the valve wall is thin, a conventional valve pressure 1.6MPa is a bit difficult.My own boundaryVacuum negative pressure 0.05Mpa-0.5Mpa0.6Mpa-1.6Mpa belongs to normal pressure (low pressure)2.5Mpa-4.0Mpa belongs to medium pressure6.4Mpa-10Mpa-16Mpa-25Mpa-32Mpa-42Mpa belongs to high pressure50Mpa-80Mpa belongs to supercritical high pressure valve
