Q:What does "q41f46-16c-dn40" mean?
DN40 refers to the nominal diameter, 16C represents 16 kg of pressure, carbon steel material F46 stands for fluorine
Q:What's the difference between a ball valve and a ball valve?
Ball valve refers to the valve for the sphere of the valve, the English BALL VALVE, ball plug valve should be said that the plug valve, the disc is like a plug like, PLUG VALVE in english,
Q:Gate valve, butterfly valve, ball valve advantages and disadvantages? What other commonly used valves?
Butterfly valve: butterfly valve is to use disc type to open and close parts reciprocating reciprocating about 90 degrees to open, close and adjust the fluid channel of a valve.Advantages: simple structure, small volume, light weight, material consumption, not for large diameter valves; the rapid opening and closing, the flow resistance is small; it can be used with suspended solid particles of the medium, on the basis of the strength of the sealing surface can also be used in powder and granular media. The utility model can be applied to the bidirectional opening and closing and adjustment of the ventilation and dust removal pipelines, and is widely used in the gas pipelines and waterways of metallurgy, light industry, power, petrochemical systems, etc..Disadvantages: the flow adjustment range is not large, when the opening of 30%, the flow will be more than 95%. Because of the structure of butterfly valve and the limitation of sealing material, it should not be used in the pipeline system of high temperature and high pressure. The general operating temperature is below 300 degrees, less than PN40. Sealing performance relative to the ball valve, cut-off valve is poor, it is used for sealing requirements are not very high places.
Q:Would you please tell me why the spring is placed in the valve seat? What's the function?
Valve seat on both sides should be added spring, the seal pushed to the valve core to seal up, so put the spring.
Q:Open the pressure relief valve core hole with what
Attention to maintenance methods of eccentric hemisphere valve:1, eccentric hemisphere valve in the closed state, there is still pressure fluid inside the valve body.2 、 before repair, release the line pressure and make the valve in the open position.3. New parts should be cleaned before assembly.4. Remove the actuating mechanism from the support before servicing.5, non-metallic parts cleaning should be immediately removed from the cleaning agent, not long immersion.6, need to be cleaned by washing the wall after volatile cleaning agent (cleaning agent can not dip silk rub) for assembly, but not for a long time on hold, otherwise it will rust, dust pollution.
Q:What is the nominal pressure 1.6p of a ball valve?
Nominal pressure: reference value relating to the pressure resistance of a piping system. For ease of use, usually the priority of the R10 series is taken. Nominal pressure refers to the pipe in the two temperature (20 degrees Celsius) when the water delivery pressure. If the water temperature is between 25 and -45 degrees, the coefficient of temperature drop should be adjusted to correct the working pressure.
Q:Which is the smallest flow valve, globe valve or butterfly valve? Which one is the biggest?
Since the flow direction of the medium through the valve has changed, so the minimum flow resistance of the cut-off valve is higher than most other types of valvesThe ball valve has the lowest flow resistance
Q:How much pressure can the flange ball valve withstand?
How many can, each kind of pressure specification has the different material quality, the thickness request, the ball valve can also use in the high pressure class.
Q:What is the ball valve Q11F -16 material?
If sealed, F stands for fluoroplastic. Valve material is not marked in the model!Q stands for ball valvesThe first 1: threaded connection,Second 1: is the ball valve is floating through the ball,F stands for PTFE- PTFE seals16 represents the nominal pressure of the ball valve is 1.6MPa=16 kg
Q:How to distinguish three points copper ball valve, two points copper ball valve
An inch is equal to eight British points, so two points is 1/4 inches, and two points on the ball are printed with "1/4", "three marks" and "3/8""
