- Q: What's the difference between the three eccentric butterfly valve and the two eccentric butterfly valve?
- Single eccentric butterfly valve: extrusion problems, address concentric butterfly valve and valve seat of the resulting in a single eccentric butterfly valve, the structural characteristics of the stem axis deviated from the disc center, so that the butterfly is no longer a rotary bottom plate, axial dispersion, reduce the excessive squeezing and the lower end of the seat of the butterfly board. Double eccentric butterfly valve: in the single eccentric butterfly valve on the basis of further improvement of forming, is the most widely used double eccentric butterfly valve.
- Q: Butterfly valve D41W-1, 41, W, 1, respectively, what does that mean?
- This butterfly valve in our factory called butterfly, 4 represents the connection of the flange connection flange is French, 41 in 1 on behalf of butterfly valve, W represents the body seal, is C that is actually the correct type of cast steel, should be D41W-1C. Suitable for ventilation, smoke, and these media.
- Q: The difference between butterfly valve and gate valve
- Its varieties and quantities are still expanding, and the development of high temperature, high pressure, large caliber, high sealing, long life, excellent regulation, as well as multi-function development of one valve. Its reliability and other performance indicators have reached a high level. Disadvantages, there is a certain resistance to the medium. Gate valves are more used in steam pipes and large diameter water supply pipelines, because of the general requirements of fluid resistance is small, the use of gate valve. Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open. Need a higher installation space, the valve sealing surface has a certain self sealing capacity, its spool by the media pressure closely with the valve seat sealing surface contact, to achieve tight leakage.
- Q: Butterfly valve model D344H and D343 difference
- In fact, almost all refers to the sealed variable eccentric butterfly valve.1, D344H-10C DN4002, D343H-10C DN400Let's talk about the similarities between the 2 Butterfly models: D stands for butterfly valves, 3 represents turbine drivers, and the middle 4 represents flanged connections,10 represents the pressure of 10 kg, C represents the butterfly valve, the material is cast steel, and DN400 stands for the caliber of the valve;To say that where there are differences between the 2 models, there is a place where there are differences, second means 4 of the first models is the new type sealing valve structure is variable eccentric, second of the second models of the 3 represents the structure of the valve is three eccentric, and three eccentric seal variable eccentric type is in fact a meaning.Sealed three eccentric butterfly valve, sealed variable eccentric butterfly valve, corresponding to the central butterfly valve and sealed single eccentric butterfly valve.
- Q: What's the material of the butterfly valve seat?
- Tianjin saide valve limited company can provide all kinds of valve seat material for the majority of users: white food gum X1 - X2 - X3 - Hypa EPDM rubber X4 rubber X5 - resistant rubber X6 - fluorine rubber X7 - heat resistant ethylene propylene rubber X9 silicone rubber and PTFE F4.
- Q: What's the difference between a clip type turbine butterfly valve and a flanged turbine butterfly valve?
- For clip butterfly valves, there are no flanges at the ends of the butterfly valve. There are only a few guide bolts. The valve is connected with the end flange with a set of bolts / nuts.In contrast, the demolition to facilitate some of the lower cost of the valve, but the drawback is that a sealing surface problems, the two sealing surfaces have to be taken apart.Flange butterfly valve at both ends of the flange, and pipe flange connection. The seal is relatively more reliable, but the valve is of relatively high cost.
- 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: Butterfly valve network and ordinary butterfly what is the difference?
- 1. The butterfly valve of the pipe network adopts an eccentric structure. When closed, it has the function of closing and tightening. The sealing performance is reliable. After opening and closing, the cover is completely sealed, and the cover is completely out of contact, so as to ensure that the sealing surface is not damaged.2, the sealing surface is made of stainless steel, corrosion resistant, high temperature resistant, long service life. With two-way sealing function, medium flow is not affected by the installation restrictions (if only one-way control medium should be used to seal the installation direction) is not affected by a single space, can be installed in the any direction.
- 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: What kind of butterfly valve is sd342x?
- Sd342x: two-way double eccentric soft sealing butterfly valveS: two way pressureD: butterfly valve3: turbine operation4: flange connection2: double eccentricX: rubber sealProbably the shape is not so good in appearance,Double eccentric mostly elastic sealThree eccentric is multi-layer sealHope to be of help to youOpened valve Co., Ltd. on the production of butterfly valve
