Q: What does "C" in D971F-16C DN450 RF mean for electric butterfly valves?
C represents the valve body and the material is cast steel;D stands for butterfly valve; 9 stands for electric; 7 stands for clip type; 1 represents middle line butterfly valve; 16 stands for nominal pressure 1.6Mpa; RF stands for flange joint; in the form of protruding surface.
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: How do hydraulic butterfly valves work?
3. butterfly valve hydraulic drive device structureThe 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. A section of optical axis is arranged at the end of the driving shaft and is inserted into the end of the manual shaft (matched with the clearance of H11/ H11), and the function is that the manual shaft is concentric with the main drive shaft. In normal operation, the optical axis rotates with the drive shaft, but the manual device does not move. When the hydraulic operation is performed manually or manually from the hydraulic unit, a * * * conversion is required. The utility model is composed of a nut, a hand wheel, a screw rod, a support frame and a shifting device. When the utility model is switched, the hand wheel is rotated and driven by the screw rod to move. A guide rod is arranged on the bracket to make the shift and translation stable.
Q: 19 years ago i had a valve repair and now im due to have heart valve replacement. I heard that the metal valve make noise has anyone who has had the metal valve have this type f problem or any other problem with the metal valve it would be a great help if anyone could answer
mechanical valves last longer where as a tissue valve will require replacement down the track. mechanical valves require blood thinners to prevent clots - long term warfarin therapy is most common - stroke is a risk and pregnancy is contraindicated. the 'clicking' is often audible by stethoscope but not without one. it is likely you could feel it 'clicking' shut and its possible you would hear it - never thought to ask any of my patients that...
Q: What is the butterfly valve
Conclusion: Although the double valve advanced technology, metrology, but must ensure stable and timely flow of materials, in order to achieve good results, so the combination of flotation system and dual use of butterfly valve can fundamentally solve the flow and measurement of powder, so as to rely on self weight principle of materials, so we plant layout the middle of a large number of mechanical equipment to save not only, more important to reduce the cost of investment and running.
Q: Butterfly valve in use when should pay attention to what problems?
In the process of using the butterfly valve, you should timely notice valve state, without excessive loosening, no abnormal leakage, or abnormal high temperature and so on, if there is abnormal, should immediately close the valve, to identify the reasons for the problem, treatment after use, it is also very important.
Q: How can the flange butterfly valve be installed on the pipe?
Outlet pipe configuration.If in the pipeline, the valve in order to do not bear the direction of the force and bending moment, it is best to set the valve at the exit side of the expansion joint. Valve opening and closing valve water pressure should not be borne by the foot, but through the valve flange, by the pipeline to bear as well.Butterfly valve structure is generally shorter length, and its butterfly plate will be extended to adjacent pipes or other parts, so be careful not to collide with other parts and interference. And to prevent the error matching pipe diameter greater than C and collide with the butterfly plate.Butterfly valve as a regulator, just adjust the flow and pressure. The valve is regulated by loss of pressure.
Q: What type of valve does the butterfly valve D343X DN300 represent?
D butterfly valve3 worm gear drive4 flange connection3, three eccentric structureX the rubber cover is rubberAccording to JB/T308-2004< valve model compilation method >
Q: The difference between vertical and horizontal butterfly valves in municipal water supply
Function is no difference, mainly the installation conditions are not the same, vertical valve shaft in the vertical direction, the valve well on the deep, horizontal valve shaft in the horizontal direction, the valve width to be larger, and the other is no difference
Q: What are the uses and classifications of manually operated clip butterfly valves?
In the butterfly valve body cylindrical channel, the disc shaped butterfly plate revolves around the axis, the rotation angle is 0 degrees -90 degrees between, when rotates to 90 degrees, the valve opens the card completely. Butterfly valves are not only widely used in petroleum, gas, chemical, water treatment and other general industries, but also applied to the cooling water system of thermal power stations.
