- Q: Why use special flanges for butterfly valves?
- Butterfly valve to use special flange, butterfly valve itself is because of the structure of the decision, the butterfly valve to clip type connection, this pair of clamps is a special flange.Also known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control the flow of air, water, steam steam, all kinds of corrosive medium, mud, oil, metals and radioactive liquid media and other types of fluid. On the pipeline, mainly from cutting and throttling. 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.
- Q: How many kinds of butterfly valves are there?
- 1. according to the structure classification (1) Central sealing butterfly valve (2) single eccentric sealed butterfly valve (3) double eccentric sealed butterfly valve (4) three eccentric sealed butterfly valve2., according to the sealing material classification (1) soft sealing butterfly valve. (2) metal hard sealing butterfly valve.3. according to the form of sealing classification (1) forced sealing butterfly valve (2) pressure sealed butterfly valve.4. classification according to working pressure (1) vacuum butterfly valve. 2) low pressure butterfly valve. (3) medium pressure butterfly valve. (4) high pressure butterfly valve. (5) ultra high pressure butterfly valve.5. classification by working temperature (1) high temperature butterfly valve. (2) medium temperature butterfly valve. (3) normal temperature butterfly valve. (4) low temperature butterfly valve. (5) ultra low temperature butterfly valve.
- 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: In the pipeline attached building Atlas 05S502, in the middle of a water meter and check valve, the two sides are divided into two butterfly valve, want to ask why to arrange this way, what is the role of the two butterfly valve?
- Check the water gauge and check valve on both sides to facilitate the maintenance and replacement of water meter and check valve.
- Q: Butterfly valve in use when should pay attention to what problems?
- After the last in the pneumatic butterfly valve after use, also need to be cleaned immediately after the valve is closed, should use soft cloth to clean the valve, which may have some impurities, dirt removal, and oil lubrication, so it can better guarantee the use of the next.
- Q: Butterfly valves are widely used in 2.0MPa below the pressure and temperature of not more than 200 degrees of various media, right?
- 3. kinds of butterfly valve:According to the connection mode: flange type, clip type.According to the material of sealing surface, soft seal and hard sealing.According to the structural form, butterfly valves can be divided into the following types:Plate typeInclined plate typeOffset plateLever type4. butterfly valve features:(1) the structure is simple and the shape is small. The utility model has the advantages of compact structure, short structural length, small size and light weight, and is suitable for large caliber valves.(2) the resistance of the fluid is small, and when the valve is fully opened, the valve seat passage has an effective circulation area, so the fluid resistance is smaller.(3) open and close, convenient and quick, good adjustment performance, butterfly plate rotation 90 degrees can be completed headstock. By changing the angle of rotation of the disc, the flow can be graded.(4) the opening and closing moment is smaller, because the butterfly plate on both sides of the rotating shaft is basically equal to the medium, and the opposite direction of the torque is generated, so that the opening and closing is more labor-saving.(5) low pressure sealing performance, sealing surface materials generally use rubber, plastic, sealing performance is good. Limited by the material of the sealing ring, the pressure and the temperature range of the butterfly valve are smaller. But the use of hard sealing butterfly valve pressure and temperature range has been greatly improved.
- 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: Butterfly valve structure and working principle
- The clip type butterfly valve is connected with the two pipe flange with a stud bolt. The flange type butterfly valve is provided with a flange on the valve, and bolts are used to connect the flanges at the ends of the valve to the pipe flange.
- Q: i just finished installing a sprinkler line for my lawn and i used anti siphon valves and 4quot; sprinkler heads. it says in the manual that it has to be at least 6quot; from the highest sprinkler. i think i made a mistake. i installed it 7quot; from the highest 'sprinkler line' . will i have a problem with that regarding the operation of the anti siphon valves and the sprinkler system itself?
- as you stated, you said the directions said at least 6 from the highest sprinkler 7 will be ok as well as 20. i don't know what region you are in, but if you are in a freeze zone though it is always a good idea to blow the lines when winter comes around.
- Q: What is the difference between wafer (flangeless) type and LUG type of butterfly valves?
- WAFER butterfly valve is the valve is divided into LUG (ears) with and without LUG, ordinary LUG without clip on 12 points in the direction of valve is generally two to four bolt holes was not, whereas the LUG of butterfly valve cross dispersed in a circle. Bolt hole. With LUG all bolted through the LUG, so that the butterfly valve and the clamp on the two flange connection is more solid, you check the valve picture, it is easy to understand
