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: Why use special flanges for butterfly valves?
- Mainly for clip type butterfly valve sealing ring on the valve body than the ordinary flange chip small diameter. Therefore, the ordinary flange can not guarantee the effective sealing effect. Therefore, you must use a dedicated butterfly flange sheet
- Q: I got my timing belt done on a 1999 Civic Si on September 26 @ 113,699 miles. at 116,9xx miles I bent a valve on my third cylinder. How likely is it that the timing belt is the reason why this happened? I heard that if the timing belt is a tooth or so off, it could bend a valve. So is it likely that this could have happened? Anyway to check?
- Yes, unless you've left out a critical detail (such as getting water into a cylinder), the timing belt is the most likely explanation for your bent valve. It doesn't neccessarily mean the person who 'did' your timing belt buggered it up, it may have just slipped. The short-ish period between getting work done and the valve getting bent is a little suspicious, but slips happen, especially with belts (as opposed to chains and dual row chains). This puts you in a difficult situation. You may also want to inspect your valvetrain, piston face, and the bore of that cylinder for damage.
- Q: My caravan is a bit sluggish on the pick up, I replaced the wires/plugs and the electronic distributor(I think thats what it is..). still a bit sluggish. Should i look at the valve gasket? Or fuel filter, or fuel pump next? 03 caravan sport 3.3L
- There is no electronic distributor on your caravan it uses a coil pack To the 1st poster there is no valve pan gasket you have valve cover gaskets. The fuel filter on your van is Incorporated in the fuel pump module located inside your fuel tank. There a several things that can contribute to sluggish performance, look at your exhaust and make sure it is not bent/collapsed/restricting Dodge Chrysler Jeep Tech
- Q: When will Butterfly Valves be used?
- Butterfly valve has the advantages of simple structure, easy operation, small footprint and light weight;1, for the city water supply network in general, DN300 still DN300 valve, butterfly valve above, this installation is convenient (especially large diameter valve installation is inconvenient, the weight of large volume, big);2, there are sediment pipeline, such as powder, mud and other mixed substances;
- 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 the butterfly valve model d344h, d345h, d346h, d347h mean?
- According to the international standard of the letters and numbers apart to explain D344H D is a unit of butterfly valve, two unit 3 is driving mode: turbine, three unit 4 connection: flange connection, four unit 4 Structure: seal type linkage, five unit H sealing material: Cr13 stainless steelD345H compare yourself to the above. Unit 5 four is a sealed, single eccentric structureD346H four unit 6 is an unsealed center vertical plateD347H four unit 7 is unsealed double eccentricIn general, there is only one difference between them: the structural form is different!
- Q: Should I connect the butterfly valve before and after the pump? Or gate valve?
- Personally believe that import and export butterfly valve or gate valve can be, or other valves. One principle, easy installation and easy maintenance.As for how much pressure can be selected according to the size of the pump flange to set the general small caliber pump are 1 and 1.6 pressure general, unless you are a super high pressure multi-stage pump, generally 1 flanges fully meet the requirements of pump working pressure is generally not too high, living above the water temperature will not exceed 40 C, so you choose the space is still very large.
- Q: Butterfly valve in use when should pay attention to what problems?
- After the last in the pneumatic butterfly valve after use, also need to be cleaned immediately after the valve is closed, should use soft cloth to clean the valve, which may have some impurities, dirt removal, and oil lubrication, so it can better guarantee the use of the next.
- Q: What's the difference between an electric two position control valve and an electric butterfly valve?
- Double switch electric butterfly valve, electric butterfly valve is usually said, namely the electric butterfly valve in the electronic case can achieve fully open or fully closed precise place to stop, not directly with the pipeline system flow feedback device for regulating the flow of accurate interaction.
