- Q:How does the pneumatic butterfly valve control the angle of opening?
- This is really not good, control seems to be pneumatic defects, can only rely on the feeling
- Q:Three eccentric hard sealing butterfly valve, why not fit in the end of the pipe?
- The sealing ring will hold up. It does not fit in with the flange end of the pipeline, this addition is the most common and convenient pipeline after purge and easily add pipeline.
- Q:What are the major disadvantages of butterfly valves?
- Rubber elastomer in the butterfly valve will cause tear, wear, aging, perforation and even shedding in continuous use. The traditional heat curing process is difficult to adapt to the needs of on-site repair. It is time-consuming and laborious to use special equipment when repairing, and it consumes a lot of heat and electricity. Nowadays, polymer composite method is gradually used instead of traditional method.
- Q:What are the classification criteria for pneumatic butterfly valves?
- The channel of the valve body inner surface smooth, fluid resistance, high CV value, strong circulation, moderate torque, the use of four seal structure and elastic rubber gasket seat with SI in high temperature aging on the outside sealing surface, zero leakage medium.Pneumatic butterfly, characteristics, there is a slit leaving the valve seat, the product is suitable for use in poor air circulation environment.The pneumatic telescopic butterfly valve is characterized in that the novel and reasonable design, unique structure, light weight, convenient operation, open and close rapidly; in addition to the telescopic valve for regulating and throttling effect, compensation pipeline temperature generated by thermal expansion and contraction function, but also for the installation of valve replacement and maintenance convenience. The sealing parts can be adjusted, replaced, sealed, reliable and so on.
- Q:butterfly valves d7a1x5
- D71x-1.6? Or D371X-1.6, do you need butterfly valves for production or butterfly valves? The question perplexed us all.
- 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 gate valve and butterfly valve, as well as cut-off valve, what are their applicable conditions? Advantages and disadvantages?
- Without strict conditions and advantages and disadvantages, of course, the equipment requires a relatively high degree of automatic control. I can check it out on Baidu.
- Q:Who was the first doctor to discover Pulmonary Valve Stenosis? Also, who was the first doctor to perform surgery for it? Please and thank you for your help.P.S. I have this condition.
- 1761 - Pulmonary valvar or valvular stenosis is one of the more common forms of congenital heart malformations and it has been extensively studied since the original description of pulmonary valve stenosis by John Baptist Morgagni in 1761. 1888 - Tetralogy of Fallot, first characterized by Dr.Etienne Fallot in 1888, is present in about 3000 children born each year in the United States. It is a combination of four heart abnormalities. Dodrill and his colleagues employed it with success for the open correction of a stenotic pulmonary valve in October 1952.
- Q:D341W-10P-400 butterfly valve, what does each alphanumeric letter mean?
- According to JB/T308-2004 "valve type programming method"D butterfly valve3 worm gear4 flange connection1 Structure: sealed type, central vertical plateW sealing material for valve body material10 nominal pressure PN10P body material is chromium nickel stainless steel400 shall be nominal size DN400
- Q:The difference between the directly buried gate and the flange valve and butterfly valve
- The flange gate valve is stable and reliable when used in the pipeline, so the flange gate valve is used on the high pressure pipeline.Butterfly valve refers to the closure of parts (valve or butterfly plate) as the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation environmental protection engineering system, conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow.
