3. Feature:
This valve is mainly composed of body, butterfly plate, valve shaft, seat and transmission devices. Simple and compact structure, small portable, convenient for transport, install and dismantle. 90 degrees of opening and closing, switch quickly, operating is small, light energy; Sealing performance is good, service life is long, can achieve zero leakages. Flow curve tending to straight line, excellent regulation performance.
The length and the same wafer butterfly butterfly valve structure. Installation can be installed to the clamp, also can be installed through the flange on both ends.
4. Sealability:
The valve for rubber seal, closing butterfly plate and seat sealing performance is good, two-way sealed good performance and the torque is small. the friction is very small between butterfly plate and the seat seal. The valve shaft drive the butterfly plate, butterfly plate do 90 degrees rotation. Butterfly plate flexible for opening and closing, no card acerbity, beating phenomenon, small torque.
- Q: Why use special flanges for butterfly valves?
- Mainly for clip type butterfly valve sealing ring on the valve body than the ordinary flange chip small diameter. Therefore, the ordinary flange can not guarantee the effective sealing effect. Therefore, you must use a dedicated butterfly flange sheet
- Q: What's the difference between a butterfly valve and an eccentric butterfly valve? What is the difference in field applications?
- Eccentric butterfly valve and ordinary butterfly valve, when the butterfly valve is opened, the eccentric butterfly valve sealing surface will reduce great wear, in the opening, the disc will leave the valve at the first time the sealing surface!
- 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: 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?
- 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: 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 are the step i need to do so i can change the valve seals my truck has been smoky.,,, any websites i want todo it myself... 1989 chevy silverado 2500 350 engine 5.7L
- If it only puffs blue smoke when you start it and then burns off after a second then its the valve stem seals that need to be replaced which is common on 350 and 305 engine prior to 1990 and have over 150,000 miles or so. The Chilton repair manual explains the procedure on how to replace these.Now if it smokes all the time then it could be caused by worn out rings on your pistons .
- 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.
- Q: What's the meaning of butterfly valve d371po?
- According to the provisions of the JB/T 308-2004 valve type programming method:D== butterfly valve3== transmission: worm gear7== connection mode: clip type1== structure: midlinePo== sealing surface material: lining PoPo== propylene oxide (PO)
