Q:What type of butterfly valves do you have in DN125?
125D42X: manual double eccentric flange butterfly valve 125D3 (6, 9) 42X: worm (gas, electricity) double eccentric flange butterfly valve125D41X: manual single eccentric flange butterfly valve 125D3 (6, 9) 41X: worm (gas, electricity) moving single eccentric flange butterfly valve125D43H: manual three eccentric flange butterfly valve (hard seal)125D3 (6, 9) 43H: worm (gas, electricity) move three eccentric flange butterfly valve (hard seal)125D71X manual alignment type butterfly valve125D3 (6, 9) 71X worm (gas, electricity) midline type clip butterfly valve125D3 (6, 9) 73H, worm (gas, electricity) three eccentric pair clip butterfly valve (hard seal)125BD71 (F4) X corrosion resisting fluorine (wrapped) pair clip butterfly valve
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:That industry uses most of the butterfly valve, and only use the butterfly valve, a large number of use of butterfly valve, seek expert advice!
I know there are automatic fire fighting systems and the oil industry.
Q:How do hydraulic butterfly valves work?
The valve hydraulic device is mounted on the valve drive shaft. The driving shaft of the valve is fixed with a transmission spline, and the crank (with an outer spline) is sleeved on the driving shaft. When the hydraulic system works normally, through the gear sleeve, the transmission spline is connected with the crank. Thus, the hydraulic cylinder drives the crank, and the spline on the crank passes the torque to the transmission spline by means of a gear sleeve. Because the driving spline is fixed on the driving shaft, the driving shaft rotates and drives the valve plate to start and close. Sorry, the picture doesn't come up
Q:Buried extension butterfly valve is buried directly, or need to repair the valve well?
The establishment of a repair valve well, easy to repair, usually hydrogen long rod butterfly valve installed in the well. But if the quality of buying long stem butterfly valve, it can also be buried directly, not easy to bad
Q:The difference between the electric control valve and the electric butterfly valve, respectively, the application situation
Butterfly valve switching speed, fluid resistance is small, but the flow control is not good, suitable for only fast opening and closing occasions. Control valve switching speed is relatively slow, fluid resistance, but the flow control of the linear good, suitable for flow control requirements of the occasion.
Q:Butterfly valve use
Butterfly valve is fully open to fully closed is usually less than 90 degrees, butterfly and butterfly stroke itself has no self-locking capability, in order to position the disc to install the valve stem on the worm gear. Using worm gear reducer, not only can the butterfly plate have self-locking ability, so that the butterfly board stops at any position, but also can improve the operation performance of the valve. Industrial butterfly valve features, capable of high temperature, applicable pressure range is higher, the valve nominal diameter is large, the valve made of carbon steel, the valve plate sealing ring using metal rings instead of rubber rings. Large high temperature butterfly valve welded by steel plate, mainly used for high temperature smoke duct and gas pipe
Q:What's the difference between D71X-16 and D71H-16 butterfly valves?
First, model D71X model means that, on behalf of 7 representative D butterfly valve, butterfly valve connection form for clamp connections, 1 straight, X represents the seal in the form of soft sealing, the sealing surface usually NBR H metal seal is usually 2Cr13 16 represents the pressure of 16 kg pressure weldingJin Ya valve is the production of hard sealing butterfly valve or soft sealing butterfly valve line leader, what problems can ask their units, technicians will answer for you
Q:What is the meaning of the D341*5-10 / 16ZB1 turbine butterfly valve flange said?
D341 is flanged connection center plate butterfly valve under pressure 1.0MPa-1.6MPa ZB1 rubber soft seal
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!
