- Q: How can a steel ball in a steel ball valve be put in?
- This kind of ball valve usually has an external direction of compression, an arrow. Usually, the ball is filled from the direction of the arrow tail and inserted or tightened into the circlip.
- Q: Manual ball valve type: Class400, 20 ', what does that mean, industrial knowledge?
- The pressure rating of the valve type and American StandardIt's a 20 inch, 400 pound valve20 inch =DN500 (nominal diameter)400 pounds equivalent to nominal pressure PN64 Mpa
- Q: For the master enlighten Q47 ball seat spring hole number is determined by how
- Force = spring stiffness (kg/mm) * compression volume (mm)Number of work cycles of spring stiffness = line diameter *1000/C 3 timesC= spring middle diameter / line diameterSpring diameter = spring outside diameter line diameterCalculate each spring force, multiplied by the number. According to the manual valve design must be greater than the pressure, pressure ratio must be large than the material allowable pressure on the line. (emphasize that here because the production process of the spring, has value of many uncertain factors, so the actual production of the spring and you cannot calculate out the same, so please choose when to consider).
- Q: What is the ball valve core?
- Valve opening and closing parts is a valve ball, the ball is also called the valve core, the ball valve is to use the stem to drive the ball around the axis of rotation, 90 degrees to achieve the opening and closing.
- 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""
- Q: PPR gate valve, stop valve, dark valve, ball valve what is the difference between the gate valve and dark valve is a thing?
- Not a thing, gate valve, globe valve, ball valve for the installation of dark valve, suitable for buried wall installation, I hope my answer can help you, Shanghai Rui River group Liaoning branch
- Q: What does the sealing surface of the ball valve stand for HF?
- HF= hard solder material in valves Q347HF, -16C, welded with CoCr or NiCr alloy.
- Q: What are the structural shapes of the eccentric hemisphere valve, what are their respective characteristics?
- The eccentric hemisphere valve and the flange gate valve belong to the same type of valve. The difference is that the closing piece is a sphere, and the ball rotates around the center of the valve body to open and close a valve. Ball valve in the pipeline is mainly used to do cutting, distribution and change the direction of flow medium. Two piece ball valve, three piece ball valve, is widely used in recent years, a new type of valve.
- Q: What does "q341" and "q347" mean?
- Valve type explanation:Q stands for ball valves;3 represents worm gear drive;4 represents flange connection;1 represents straight through floating ball, and 7 represents straight through fixed ball.Therefore, Q341 is a turbine driven flange straight through floating ball valve, Q347 is a turbine drive flange through fixed ball valve.
- Q: Home tap water valve (ball valve) half open or well open, open half is not love rust live?
- Open big, small, same, as long as the pressure is enough, enough flow does not matter. The effect is half open, with a sound.
