A butterfly valve consists of body ,stem ,disc , actuator (manual actuator, worm-gear actuator , aerodynamic actuator or electric actuator) , and wafer type butterfly valve can implement the process for turning on turning off and regulating the flow by the circumrotation of stem and disc that is droved by actuators.
1.Simple and compact construction. Small in size and light in weight. Easy transportation, installation and maintenance.
2. Quick 90 degrees on-off operation. Minimized operating torque ,energy saving.
3. Excellent sealing performance with no leakage. Long service life.
4. Wide selection of materials ,applicable for various media..
5. Flow curve tending to straight line. Excellent regulation performance.
- Q: What's the use of fire butterfly valve?
- You should ask the signal butterfly valve, butterfly valve in the fire signal system which is a monitoring alarm signal, its purpose is to ensure that the valve has been opened in the daily state, to prevent misuse operation was closed, thus affecting when accidental fire extinguishing. Therefore, it is necessary to set up the signal valve!
- Q: Butterfly valve D41W-1, 41, W, 1, respectively, what does that mean?
- D--- stands for butterfly valves; 4--- refers to the form of flange connections; 1--- refers to the valve stem and disc in the center of the valve line, without eccentricity; w--- refers to the valve seat material and body material is the same, usually carbon steel. The final 1--- refers to the nominal pressure of 1 kg / cm2.
- Q: What's the difference between a clip on handle butterfly valve and a turbo butterfly valve? Where are they used?
- Depending on the size of the valve and the opening and closing torque, the transmission mode is different (handle or turbine).
- Q: What does butterfly valve nps12cl150d373f4-150lb stand for?
- NPS (Nominal, Pipe, Size) abbreviation. Refers to the connection (including flanged and welding end) of the nominal diameter, followed by a digital unit is American Standard inches, 12 inches.NPS12 labeling system.CL is the abbreviation for class, and LB150 means the pressure is 150 poundsD stands for butterfly valves3 is expressed in the form of a turbine drive7 means of connection: to clip3 means sealing: 3 eccentricF4: the sealing material is PTFE
- Q: What's the difference between a clip type turbine butterfly valve and a flanged turbine butterfly valve?
- The clamp and flange are the two connections.The clip type is cheaper and the price is approximately 2/3 of the flange.The length of the clip type valve bolt is longer, and the requirement of construction accuracy is higher. If the flange on both sides is wrong, the bolt will be subjected to greater shearing force, and the valve will leak easily.
- Q: The water supply pipe is the gate valve And on the cross dry pipe are the gate valve? To answer the 30
- 1, this is a good question, it seems that this has not yet made a unified standard requirements, a bit confused2, personal understanding of fire water supply pipe, pipe shall be installed on the valve, because the valve is fully open all closed features of fire control system is usually required is fully open, easy management features are obvious.3, fire water supply system is also useful to butterfly valve, but mainly signal butterfly valve.The signal butterfly valve is generally installed in two parts: floor level, dry pipe, flow indicator front end, trunk pipe, wet alarm valve, front end.Floor level pipe installation is a function of the signal valve, when the floor spraying system needs repair, close the valve, open the end of the floor drain, emptying the water in the spray system, maintenance; two is the sprinkler system is not allowed inside water, when the butterfly is closed, will transmit a signal to the the fire alarm system, fire alarm system receives a monitoring signal (so called signal butterfly valve), fire sprinkler system that the floor is anhydrous state, fast repair.Wet alarm valve at the front of the signal butterfly valve with the main floor of the main role of the butterfly valve, first, maintenance, and two is the prompt sprinkler system, there is a signal butterfly valve closed, should be repaired as soon as possible.
- Q: Seat has said to the previous owner that the car needs a new air mass meter and dump valve.I am putting a new air mass meter on it.Does it have a dump valve.I know very little on this subject.
- every turbo will have a dump valve(waste gate) to regulate the boost to the engine Dump valves are fitted to the engines of turbo charged cars and sit between the turbo outlet and the throttle body. When transitioning from a boosted state to a closed throttle state (as in between shifts), due to inertia, the turbo continues to pressurize air, but the closed throttle prevents the compressed air from entering the engine. In this case the pressure exceeds the preset spring pressure in the dump valve and the excess pressure is bled off to atmosphere. Even with a dump valve the compressed air acts as a brake on the turbo (slowing it down), because the pressure on the backside of the turbo is at a higher pressure than on the front side (and the air actually wants to flow through the turbo backwards). A blowoff valve is a more elegant solution to this problem by allowing the turbo to freewheel when the throttle is closed (equalizing the pressure on both sides of the turbo). Unlike a dump valve a blowoff valve can be used at multiple boost settings without reconfiguration. Blowoff valves are sometimes incorrectly called dump valves because they serve a similar function, but they are very different solutions to the same problem.
- Q: Water supply pipe gate valve and butterfly valve which good?
- Butterfly valve is relatively applicable1 electric butterfly valve 0-90 degree rotation angle stroke valve, specific flow characteristics, small size, high performance price ratio2, electric valve up and down movement of the straight stroke control method, can be used as shut-off valve, large size, expensive3, electric butterfly valve can not be used for high temperature and high pressure conditions, not wear-resistant. Electric gate valve is generally used to close the material with a grain of material, suitable for high temperature and high pressure conditionsOur company specializes in the production of various types of valves, there is a need to help me, I would like to help
- Q: How is the lug butterfly valve connected to the flange?
- When installing, pay attention to the butterfly plate. The sealing ring between the flange face and the butterfly valve is tightened. After clamping, it can be tightened.
- Q: D what's the meaning of "one 71x one 1 butterfly"?
- According to the provisions of the JB/T 308-2004 valve type programming method:D== butterfly valve7== clip typeLinetype in 1==X== sealing surface material: Rubber-1== pressure rating: 1.0MPa
