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: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:What's the difference between a clip on handle butterfly valve and a turbo butterfly valve? Where are they used?
- Just drive differently,Handle butterfly valve is generally small caliber, because generally small caliber torque smaller, can be directly opened and closed by handTurbine butterfly gear box drive stem rotation.The selection principle for when the stem torque is greater than 300N.M when used in gear box drive gear box, and use the handwheel control hand wheel force is not greater than 300 nm.
- Q:Which is better, the round two lobe butterfly valve?
- Round type double butterfly butterfly valve is the first choice of Shanghai Machinery & Equipment Co., Ltd., the company is a professional design, manufacture and sale of central air-conditioning products at the end.
- Q:Today saw the butterfly valve and butterfly valve, I do not know what is the difference between the two
- It should be the same. Butterfly valve (also called butterfly) English Name: butterfly valve: headstock disc disc disc plate and can rotate around the axis of the valve body of a valve rotating. Construction: mainly composed of valve body, valve stem, disc and sealing ring. The valve body is cylindrical and has short axial length and is internally provided with a plate.
- Q:What is the working principle of the electric butterfly valve, and what's the difference between the butterfly valve and the butterfly valve?
- Signal butterfly valve is generally can achieve full clearance of a valve opening electrical signal output, the general requirements of the electrical signal isPassive electric shock signals are mostly used in fire fighting systems, such as the need for valve position feedback;The electric butterfly valve is not necessarily the signal butterfly valve, because the electric butterfly valve does not have the requirement of the source contact.
- Q:What is the meaning of American Standard butterfly valve B series
- American Standard flange connection is divided into A, B series. A series for normal flanges, B series for compact flanges. 24 "to no AB series, flange standards for B16.5, 24" above B16.47.
- Q:16 inches below the choice of electromagnetic valve can be the same, it turned out to be DN200 election 1/4, and now there are DN350 can also use this? With it, limiter, pressure relief valve, locator model will change?
- The valve (including the valve, butterfly valve, etc.) are equipped with pneumatic actuators are standard (including restrictor valve positioner of the electromagnetic valve is connected with the installation.) is the international standard NAMUR standards, in the standard of inside electromagnetic valve is G1/4, of course, this is the solenoid valve installation in the NAMUR interface of the driver on the situation, if the solenoid valve is not installed on the drive, but through the trachea installed in a few meters away, it would have to choose a larger size, how to choose? Depends on the switching speed of the valve requirements, such as drive gas consumption is 2L, need to open in 1S, the electromagnetic the valve requires the flow of 120L/min, plus the line loss and acceleration, 500L/min is enough.
- Q:Why anti condensation of aluminum alloy anti condensation butterfly valve?
- Anti condensation butterfly valve multi-level unique progressive contact seat design, the valve plate in close contact in the process of gradually seat, ensure good sealing performance while reducing unnecessary torque, and the butterfly plate of stainless steel and the inner parts, thereby prolonging the service life of the valve seat, has strong rust and corrosion function. Torque reduction enables the drive to be lightweight and miniaturized. Unique stem seal prevents fluid leakage.
- Q:What does "C" in D971F-16C DN450 RF mean for electric butterfly valves?
- Valve carbon steel -16c body 316 stainless steel -16r
- Q:Should I connect the butterfly valve before and after the pump? Or gate valve?
- 1, valve, the fluid resistance is small, the sealing surface by the erosion of small and medium Chong brush. 2, opening and closing more effort. 3, medium flow unrestricted, no disturb, do not reduce pressure. 4. The shape is simple, the structure length is short, the manufacturing technology is good, and the scope of application is wide. Butterfly valve main deficiency is that it uses the pressure and temperature range is small. And poor sealing. Therefore, the gate valve should be preferred.Gate valve (gatevalve) is a gate valve used to open and close parts, and along the vertical axis of the valve seat movement, in order to achieve the opening and closing action of the valve. The valve can only be fully open and fully closed, opening and closing parts is the gate, the direction of motion perpendicular to the direction of the fluid, valve two square I-shaped sealing surface forming the wedge, the wedge angle varies with the valve parameters, usually 5 degrees is not high, medium temperature is 2 degrees 52'. Improve the process of valve, make up the sealing surface angle in the process of production deviation, this kind of gate is called flexible gate.
