- Q: How do you draw the butterfly valve in the engineering drawing?
- Butterfly valve there are many kinds of painting, according to the design institute out of the icon, below we together to understand the icon, which has the butterfly drawing.
- Q: Butterfly valve is the control valve?
- The flow characteristics of butterfly valves can be approximately equal percentage characteristics, with the positioner can do adjust, is mainly used in large caliber, straight stroke control valve more than 200 volume weight will be great, it suggests using the butterfly valve.
- Q: The flow ratio of area and maximum flow area of the valve is? If it refers to the opening of the valve rotation angle? Butterfly linear closure refers to the butterfly valve at constant angular velocity close? When the change trend of flow is what? These valves problem bothering me for a long time,
- Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis rotation, so as to achieve the opening or closing or adjustment; actuators have electric or pneumatic, and so on, through the transmission device to drive the stem, valve plate rotation;
- Q: What's the difference between turbine butterfly valve and manual butterfly valve?
- Butterfly (Manual butterfly) butterfly plate installed in the direction of the diameter of the pipe. In the butterfly valve body cylindrical channel, the disc shaped disc rotates around the axis. The angle of rotation is between 0 and -90 degrees. When rotating to 90 degrees, the valve is fully open.Butterfly valve structure is simple, small size, light weight, only by a few parts. The utility model can be rapidly opened and closed only by rotating 90 DEG, the operation is simple, and the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the butterfly plate thickness is the only resistance when the medium passes through the valve body, so the pressure drop produced by the valve is very small, so the flow control characteristic is better. Butterfly valve has an elastic seal and metal seal, two types of seals. Resilient sealing valve. The sealing ring can be mounted on the valve body or attached to the periphery of the disc.
- 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: Gate valve, butterfly valve and so on can do the valve so that?
- Do a lot of use valve and butterfly valve, pneumatic / hydraulic, or electric device, automatic control valve, adjust its switch angle, so as to achieve the purpose of regulation. For example, in the factory, in order to ensure the top pressure, then the pressure regulating valve, the valve is automatically adjusted by a butterfly valve! And there is also pressure regulator, pressure regulator valve series is used independently. Of course the more, is mainly used to adjust the flow!
- Q: How do the butterfly valves d341 and d343 differ in appearance?
- A difference in appearance:D341 is a wedge type single gate structureThe D343 is a parallel single gate structureIn addition, the structure is different. D341 butterfly valves are single eccentric, while the D343 is three eccentric. Three eccentric can do zero leakage, and single eccentric can not.D341:D: butterfly valve (die, the first letter of Pinyin)3: turbine drive (6) for pneumatic, 7 for hydraulic, and 9 for electric)4: flange connection (this additional: 7 for the pair, 6 for welding)1: midline form (another supplement: 2 represents double eccentric, 3 represents three eccentric)D343:D: butterfly valve abbreviation3: hand wheel drive4: flange type3: three eccentric.
- Q: Butterfly valve D71X-1.6C, DN50, there is no difference between C and no C? What do you mean by "concrete"?
- The C indicates that the material is carbon steel and does not indicate cast iron (generally omitted)
- Q: How to connect the signal butterfly valve?
- The signal butterfly valve should be the surveillance and alarm of human action. Once it is closed, it will alarm the system.Signal butterfly valve wiring method:1, open the switch box cover, according to the electrical control requirements, the cable core line to the corresponding terminal, and sealed cable imports, while the cable fixed, to prevent external force damage when the cable wiring.2, when the valve in the "closed" position, the clockwise rotation of the following relationship to the cam is just touch micro switch cam (you can hear the clicking sound), and then tighten the screw on the cam cam.3, when the valve in the "fully open" position, counterclockwise turn the upper open cam, with the same method to adjust the open cam.4, adjust the limit screw, when the valve in the "full off" or "open" position, should not make the limit screw just at the top of the worm gear limit plane, and should have a certain gap, and then tighten the lock nut on the screw.5, on the cover of the electrical switch box cover, when the valve in the "off" position, the pointer opening indicator to dial "0" scale, and tighten the screws pointer.
- Q: I have a good set of #142 Pontiac heads with small diameter valves. I want to have the heads enlarged to accept the larger Pontiac valves, and I have the larger exhaust valves out of #13 heads and the larger intakes from 6X8 heads. The valves appear ok and shiny on the stems
- If the valve is burnt there is no longer something you're able to do with it yet replace it. in the event that they simply desire cleansing up you could lap them in with a lapping compound the threat with this is which you would be able to desire to visual exhibit unit which you don't get close to to the sting of the valve, this is once you will finally end up with a burnt valve. The valve should not be flush with the valve seat this is plenty to close and the warmth of combustion could have an more advantageous effect on the textile.
