- Q: What does "10" in the butterfly valve "D71X-10" mean?
- The pressure of 10 kg 1.0MPA is usually cast iron
- Q: What's the size of the signal butterfly valve sleeve?
- The output signal is stable and reliable for a long time. The valve has an electric node, which is drawn out to the control center by signal line, and the signal line voltage is 12V. In fact, the valve is open and closed, there is a signal to the consumer control center, easy to monitor, the valve in addition to the electric node, with the ordinary valve is not much difference, there are also signal butterfly valve. When setting a quota, cover a valve, and then set 13-156.Door closer, 7-194 and 13-1013.Fire phone 7-188.Fire radio 7-382
- Q: In the pipeline attached building Atlas 05S502, in the middle of a water meter and check valve, the two sides are divided into two butterfly valve, want to ask why to arrange this way, what is the role of the two butterfly valve?
- Check the water gauge and check valve on both sides to facilitate the maintenance and replacement of water meter and check 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 "opening - flow" curve in the flow of 25%-75%, that section is basically linear. That is, the opening of 40%, that flow is about 40%Butterfly valve opening degree of 0.5, should be opened 50%, that is, opening to 45 degrees;
- Q: Water supply pipe gate valve and butterfly valve which good?
- 1. gate valve: also known as gate valve or gate, there is a valve in the valve flow direction perpendicular to the medium, adjust the height of the gate, you can adjust the flow of fluid. Valve advantages are small resistance, close tight, no water hammer phenomenon, widely used in a variety of liquid and gas shut-off valve. It also has some adjustment function, but when the part is opened, the gate is easy to be wetted by the fluid. When the fluid flows, it causes the shaking of the alarm board and the sealing surface is easy to wear. The drawback of the gate valve is that the structure is complex, the price is more expensive, it is difficult to repair, and the solid material is easy to deposit in the valve seat groove. Therefore, it is not suitable for the pipeline containing fiber or solid material in the fluid. Commonly used in the air, steam, oil medium pipeline, but also used as vent valve and low silk system valve.Gate valve is commonly used as one of the cut-off valve, mainly used to connect or cut off the medium in the pipeline, not applicable to regulating medium flow. Valve is suitable for pressure, temperature and caliber range, especially for medium and large diameter pipes.
- Q: What are the classification criteria for pneumatic butterfly valves?
- The channel of the valve body inner surface smooth, fluid resistance, high CV value, strong circulation, moderate torque, the use of four seal structure and elastic rubber gasket seat with SI in high temperature aging on the outside sealing surface, zero leakage medium.Pneumatic butterfly, characteristics, there is a slit leaving the valve seat, the product is suitable for use in poor air circulation environment.The pneumatic telescopic butterfly valve is characterized in that the novel and reasonable design, unique structure, light weight, convenient operation, open and close rapidly; in addition to the telescopic valve for regulating and throttling effect, compensation pipeline temperature generated by thermal expansion and contraction function, but also for the installation of valve replacement and maintenance convenience. The sealing parts can be adjusted, replaced, sealed, reliable and so on.
- 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: What is the national standard for clip butterfly valves?
- GB/T 12238-2008 "flange and clip connection elastic seal butterfly valve"GB/T 26144-2010 flanged and clip on steel lined fluoroplastic butterfly valvesJB/T 8527-1997 "metal sealed butterfly valve"
- Q: I HAVE A 2003 FORD EXPEDTION THAT IS IDLE ROUGH,AND WILL EVENTUALLY STALL. TODAY I FOLLOWED THE PCV VALVE HOSE TO THE BACK OF THE THROTTLE BODY AND NOTICED THERE IS A BIG HOLE ON THE ELBOW OF THE HOSE. HOW CAN I CHANGE IT? CAN I JUST FORCE THE HOSE OUT AND SIMPLY PUT A NEW ONE? BEEN HAVING THIS ROUGH IDLE /STALL PROBLEM FOR A WHILE I CLEANED IAC VALVE, THROTTLE BODY CHANGED THE AIR FILTER AND ALSO CLEANED THE MASS AIR FLOW SENSOR, I HAVE A P0171 system to lean(bank 1) code
- just undo the clamps, and pull. it may need some wiggling and tugging, as its been on there for 9 years now without moving. put on your new hose, and replace the clamps, and youre done. next time, try not using all caps. it doesnt make us want to answer your question anymore just because its in caps, in fact, maybe a little less.
