5.FAQ
1. What is manual wafer butterfly valve?
A: Wafer style is the more common of the two and is less expensive than the lug style. The wafer style butterfly valve is just about the standard. It ís so common that no one even bothers to use the word "wafer" when ordering a butterfly valve. It is taken for granted that if a butterfly valve is ordered, a wafer style will be received.
2. What is the working principle of manual wafer butterfly valve?
A: A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.
- Q: What's the size of the signal butterfly valve sleeve?
- The signal valve of the fire door (not in the signal valve shutter doors, fire signal valve use: top fire signal butterfly valve with the valve opening and closing signal device, when the valve is closed by 25% (open degree 4/1), the signal device output signal was mistakenly closed to the fire control center. Therefore, this butterfly valve is the best matching product of automatic fire sprinkler system.
- Q: Not the cold and hot water shut off valves. The one with a tiny handle and it looks like a T. what does it do? should I mess with it?
- Well definitely should not mess with it, especially if you do not know exactly what it is and more important what it controls. If not water, then it could possibly be the shut off for a near by gas appliance. It would help if you described the size and color of the pipe. Maybe you could try to trace it , where does it come from and where does it go to ?
- Q: What do D71, D371 and D341 represent in butterfly valves?
- D71 stands for middle line to clip butterfly valveD371 represents the worm wheel centerline pair clip butterfly valveD341 stands for worm gear flange butterfly valve
- 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: Function of signal butterfly valve in fire sprinkler system
- 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: Do you use the straight stem butterfly valve in the fire fighting engineering?
- Only the gate valve clearly rod and dark pole, butterfly valve classification is the clamp type and flange type, Zhengzhou butterfly valve factory, Mr. Zhao
- 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: How do hydraulic butterfly valves work?
- Butterfly valve hydraulic drive device working principle1. manual operationWhen the hydraulic system suddenly fails, the valve can not move when the butterfly plate at any stop. Then, shaking the manual device, the guide block guide block in front of the manual shaft together with the driving shaft end, the cogging and drive shaft spline manual corresponding to the slot. Then, by dialing the driving device, the dial is shifted to the left end, and the transmission spline is connected with the manual shaft by a gear sleeve (the driving device is provided with a limit for preventing the tooth sleeve from jumping up), and the crank is disengaged from the hydraulic cylinder to disengage the hydraulic cylinder. Then turn the manual device and use the manual device to realize the disc movement.2. hydraulic operationWhen the hydraulic system returns to normal operation, the actuating device needs to be operated by hand. First, adjust the hydraulic cylinder to its initial state (0 digits) or at any position. Then manually adjust the opening of the disc to the position corresponding to the cylinder stroke (by observing whether the mark on the gear sleeve is in accordance with the mark on the crank, and judge the position of the disc and the cylinder). Then pull the gear sleeve and engage the spline on the crank by poking the driving device. Then fix the shift to prevent jumping. At this point, start the hydraulic system to restore fluid flow.
- Q: Three eccentric hard sealing butterfly valve, why not fit in the end of the pipe?
- Three eccentric hard seal butterfly valve quality standards, up to zero leakage, but you mean the end of the direct discharge?If so, that's OK. First you have to calculate how much the pipe fluid pressure is.For example, the pipe fluid pressure is highest and the pressure is 1.6MPa (16 kg)Should choose three eccentric hard seal butterfly valve should be pressure 1.6MPa (16 kg)If you worry, optional 2.5MPa (25 kg) will not leak!Answer: three eccentric hard sealing butterfly valve can be installed at the end of the pipe
- 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)
