FAQ
- What's the meaning of the double ball valve in the double ball valve?
- By means of "union", the "live" means that the two ends of the valve are connected by a live joint
- Would you please tell me why the spring is placed in the valve seat? What's the function?
- The spring can also reduce the impact of the material on the valve.Ball valve (ball valve), standard GB/T21465-2008 "valve terminology" is defined as: "open and close parts (spheres) driven by the stem, and around the axis of the ball valve for rotation of the valve.". Can also be used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fibers, small solid particles and other media. Switch and multi way valve in the pipeline not only can flow, and flow diversion, flexible control of the medium, but also to turn off any channel to the other two channels. This kind of valve should be installed horizontally in the pipeline. In accordance with the way to drive the ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball valve.
- Q4110 what is the ball valve? What does each number stand for?
- It's Q41-10Q- stands for ball valves; 4- stands for connecting flanges; 1- is straight through floating ball; 10 means valve bore 10If it's Q4110, you're not sure
- 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
- 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.
- What does telescopic ball valve mean? What does it mean?
- An expansion valve is mostly for repair or replacement of the water meter behind the expansion is the activity space, for example for water when the water meter is just let it back so easily won, for good and put it out to tighten the gentry good handle table.
- Ball valve 11F, 41F, 11H, 41H
- The ball in, 11F first said the connection mode of "1" threaded connection, second said that the structure of "unit valve 1" straight through, third said "F" said sealing material is PTFE seal;
- Who knows why the ball valve is divided into a piece of ball valve, two pieces of ball valve, three pieces of ball
- There is, of course, a difference,This is according to the structure of the valve body,The difference between them is whether they are easy to disassemble, for example, the three piece of ball valve is easiest to disassemble.
