- Q:1. What does valve 13Cr&FHF mean? 2, valve WC6 (F11) what does that mean? 3. What does valve P280GH mean? 4. What does valve A335P22 mean?Thank you
- May be non-standard label bar, do not understand, A3 should refer to the body, the material is 13Cr.
- Q:What is the difference between the adjustable range of valve 50:1 and 100:1?
- Said is the valve bar, adjustable valve range refers to the adjustable ratio, that is, the maximum flow control valve can be controlled with the minimum flow ratio.The regulating ratio of the regulating valve is the ratio of the maximum flow and the minimum flow that the control valve can control.
- Q:Which brand of electric valve is good?
- SIEMENS (Siemens, Germany); the main HVAC control valve; Johnson (Johnson, America); electric valve; Honeywell (Honeywell, USA); electric control valve for building; Wu mountain (YAMATAKE, Japan); valve; Bo Li Mou (Belimo, Switzerland); Danfoss (Danfoss ball valve, butterfly valve, Denmark); butterfly valve, gate valve, globe valve (aka ARCA, Germany); the control valve iResearch (ARI, Germany); the pressure relief valve, safety valve; Hank (HANK, Germany); pneumatic valve; KITZ (Japan); gate valve, globe valve, butterfly valve, ball valve, check valve; contact SIEMENS, Johnson, Honeywell, Shanwu, aka more;
- Q:How can you replace the other valve when the main valve is not closed and no water is stopped?
- Not recommended against the flood to repair the valve, first you have to be repaired, second may be more complex, it is not easy. I have a bad experience this, take the valve, because it is plastic, and aging, the thread is broken, the new is not on do not have to flow out of the water, get it is. To find the valve, the mess!
- Q:the use of natural connections, is strictly prohibited counterparts. What do you mean by "strong opposition"?
- Refers to the installation of the interface dislocation, misalignment or installation of the wrong size and forced connection, resulting in installation stress exists, in use, it is prone to abnormal damage.
- 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:Is there any problem with connecting the geothermal valves with other geothermal pipes?
- Yes, as long as it's all PPR's.Material is the same, the fuse will not cause shrinkage when you can use
- Q:How do you calculate the valve wall thickness, pressure, and other valve design calculations in a spreadsheet?
- The valve wall thickness is the standard valve check directly in the relevant standard, for insert grade valves need to use interpolation method to calculate the valve wall thickness, actually don't need what difficult to complete in EXCEL software.
- Q:What is the term "Z41H-16C" on the line?
- When Z41H-16C opens the valve, when the gate lift height is equal to 1:1 times the valve path, the passage of the fluid is completely unblocked, but at run time, this position is not monitored. In actual use, the top of the stem is used as a sign, i.e., the open position, as its fully open position. Temperature changes appear to consider locking phenomenon, usually open to the vertex position, and then rewind 1/2 1 circle, as a fully open valve position.
- Q:How can the material be checked by valve approach? What experiments do you need?
- May refer to the valve pressure test principle and the pressure test matters needing attention.(1) in general, the valve shall not be subject to strength test, but the body and bonnet shall be subjected to strength tests after the repair of the valve body and bonnet or corrosion damage. For the relief valve, the constant pressure and seat return pressure and other tests shall be in accordance with the specifications and the relevant regulations.(2) the installation of the valve should be done for strength and tightness test. Low pressure valve sampling 20%, if not qualified should be 100% of the inspection; medium and high pressure valve should be 100% of the inspection.(3) the installation position of the valve shall be in the direction of easy inspection during the test.(4) welding connection valve, not with blind plate pressure test can be used when the cone seal or O ring seal pressure test.(5) when hydraulic test, the valve air will be excluded as much as possible.(6) the pressure should be increased gradually during the test, and the pressure will not be sudden and sudden.(7) strength test and sealed test duration is generally 2~3min, important and special valves should last 5min. Small caliber valve test time can be a little shorter, large caliber valve test time can be longer. During the test, the test time can be extended if in doubt. Strength test, does not allow the body and bonnet sweating or leakage. Sealing test, the general rotor valve only once, the safety valve, high pressure valve and other raw valve to be carried out two times. When testing for the low pressure, large diameter valve is not important and there are provisions to allow leakage of the valve, allowing a small amount of leakage; the common valve, power station valve, marine valves and other valve requirements vary on leakage requirements according to relevant regulations.
