- Q: 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
- Q: Ball valve 11F, 41F, 11H, 41H
- 41F flanged ball valve type sealed through using tetrafluoroethylene; 11H is threaded through valve type the alloy steel seal;
- Q: What does "DN PN" mean? DN25 PN18 stands for what is the thickness? With the usual said 4 in charge of what's the relationship?
- PN nominal pressure.Definition：Relating to the mechanical and dimensional characteristics of the components of the piping system and the identification of letters and combinations of numbers for reference. It consists of letters PN and followed by dimensionless numbers.Note 1: numbers followed by letters "PN" do not represent measurements and are not used for purposes of calculation unless otherwise specified in the relevant standards.Note 2: is not associated with the relevant pipe component standards, but the term "PN" does not make sense.Note the 3: piping element allows the pressure to depend on the PN value of the element, the material and design, and allows the operating temperature, etc., to allow the pressure to be given in the corresponding standard pressure temperature class table.Note 4: all pipe elements with the same PN and DN values shall have the same mating dimensions as their flanges.The latest definition of PN comes from standard GB/T 1048-2005, the definition and selection of pipe component PN (nominal pressure), and is referenced in the standard of pipe fittings and tubing. GB/T 1048-2005 7268:1996 Pipe components - modified ISO/CD Definition of nominal pressure, a "note increase than the original standard: allow numerical" choose other PN when necessary, namely in the PN series, you can use other numerical PN.
- 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: The toilet water pipe valve is broken, with a new twist, how are the screw does not move, then they told me to go on to the pipe on the water and then tighten, did as he said, really screwed, but do not know why, please tell the master what is the principle, if it is water without water when the screw does not move, but when the water can twist. What a kink!Is the water valve normal, a pull rod, pulling it back flush, do not rush the kind, the middle is a hollow ball
- I think it should be the water holding gas, connecting device principle, at the bottom of the hand, barometric pressure, and the best you can last map, I'll see
- 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: What is an eccentric hemispherical valve? How do you understand?
- 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.
- Q: How to distinguish between single and double ball valve?
- Single ball valve, pneumatic ball valve is a single short; double valve, double acting pneumatic ball valve is referred to as.Single acting pneumatic ball valve is open air, spring off; and double acting pneumatic ball valve, gas gas is closed.Single / double ball valve, is divided according to the actuator, the actuator has a single pneumatic actuator and double acting pneumatic actuator.Single acting pneumatic actuator Pneumatic actuator to more than double spring, loss of gas supply, the spring to reset actuator.For hazardous media or conditions requiring a safe position when the gas source is lost, a single action is recommended.Selection must be based on the size of the field air pressure to select the spring force, otherwise it may cause air pressure is less than overcome the spring force and can not drive the actuator.When the actuator is selected, the minimum spring force should be allowed to drive the valve normally, taking into account the gradual reduction of the spring force.
- 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: Structure design principle of fire ball valve
- 5 ball valve seat structure typical fire abroad professional production company common pipeline ball valve seat structure design of typical figure 9 - 12 shows, each seat structure fireproof structure design is reasonable, to ensure the seat piston effect of the sealing ring and the valve seat seal failure, valve seat leakage way at least. Figure 9 rubber sealing seat 1 to the left to the right in Figure 10 | rubber sealing seat 2 to the left to the right | Figure 11 rubber and plastic combined sealing seat to the left to the right in Figure 12 | plastic seat to the left to the right seat | fireproof structure design reasonable, can guarantee the way upstream pressure medium through the valve seat leakage at least fire, the best performance. In the design of fireproof structure of pipeline ball valve, the fire protection structure design of valve seat should be paid more attention to. The seat of fire with reasonable structure is the fundamental guarantee of fire safety in the pipeline valve in practical engineering, reasonable assessment of structural fire protection should be strictly in accordance with the API6FA/API607 standard fire test, test samples should not be sample makers, should be the verification institution with sampling, so as to ensure the rationality of the third party authentication and notarization of.
