- Q: DN80/DN100/DN125 how big is the outer diameter of the ball valve flange?
- In addition to the three common, flange standard complex, a long story.All kinds of standards, there is a little difference in thickness, diameter of flange, bolt hole number, but the flange bolt hole parameters of the same pressure level (bolt circle diameter K, bolt diameter L, bolt number N) are the same.
- Q: What do you mean by ball valves dn20pn1.6rf?
- DN20 caliber is 20mmPN is the pressure grade, usually PN16, 1.6MPa classRF convex flange connectionYour side should be similar to the Q41F-16 model of this type of ball valve
- Q: What does W represent in copper ball valve Q11W-16T?
- According to the provisions of the JB/T 308-2004 valve type programming method:Q== ball valve1== connection: internal thread1== ball valve structure: straight through flowW== sealing surface material: body. That is, the sealing material is the same as the body material-16== pressure rating: 1.6MPaT== body material: copper or copper alloy
- Q: Gate valve, ball valve, the difference between the pressure regulating valve
- Gate valve and stop valve are shut-off valve, is the most common two valves. From the exterior, the gate valve is shorter than the cut-off valve, especially the bar valve needs a higher height space. Valve sealing surface has a certain degree of self sealing capacity, its spool depends on the media pressure tight contact with the valve seat sealing surface, to achieve tight leakage. Wedge gate valve spool angle is generally 3~6 degrees, when forced to shut down excessive or temperature changes of the valve core is easy to die. Therefore, high temperature and high pressure wedge gate valve, in the structure have taken certain measures to prevent spool stuck. The valve in the opening and closing valve and valve seat sealing surface contact and mutual friction is always so easy to wear sealing surface, especially in close off the valve, the valve before and after the great pressure, sealing surface wear is more serious. Compared with the cut-off valve, the main advantage is that the flow resistance is small, the flow resistance coefficient of ordinary gate valve is about 0.08~0.12, while the ordinary cut-off valve resistance coefficient is about 3.5~4.5. Opening, closing force is small, the medium can flow in two directions.
- Q: The difference between a cricket valve and a constant pressure valve
- Ball valve for ball ball column shape and called, is mainly to be closed, and often switch when the fluid flow control to throttle function and design, is the main characteristic of effective throttling, to minimize and reduce the phenomenon of drawing valve and valve seat dip (wash) inhibition, but because of the seat is parallel to the line, change the flow of fluid through the valve seat will be in class.
- Q: What's the difference between a ball valve and a butterfly valve? Which one has better sealing performance?
- (3) butterfly valves are divided into soft seal and seal, soft seal butterfly valve is generally perpendicular to the center of the plate, is the valve plate, valve seat, valve stem is the center position of the highest temperature soft sealing butterfly valve is 150 degrees below the pressure of 16 kg, hard seal butterfly valve can be divided into single eccentric, double eccentric three, the eccentric, we generally use more than three eccentric, because the three eccentric according to its structure, better sealing performance, hard seal butterfly valve pressure is 64 kg;(4) the valve can also be divided into soft seal and seal, soft seal valve can reach the highest temperature below 280 degrees, the pressure is below 64 kilograms, hard seal ball valve temperature can reach 425 degrees below the pressure below 100 kilograms.
- Q: How to distinguish three points copper ball valve, two points copper ball valve
- I. identification methods:Three points, two points mean the specifications of the ball valve, three refers to the diameter of 32, two refers to the diameter of 25.Two, copper ball valve is a brief introduction:The ball valve is mainly used to cut off or connect the line of medium, can also be used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fibers, small solid particles and other media.
- Q: What is retractable hemispherical valve? What's the area with the manual hemisphere valve?
- Telescopic hemisphere valve is a telescopic hemisphere valve, ordinary hand hemisphere valve, of course, without expansion joints.Telescopic ball valve is a combination of expansion joint and ball valve.
- Q: Why is there a water or oil in the new ball valve?
- When the product goes out of the factory, we should do the closed water pressure test. There are two ways to check the spot and follow the pieces.
- Q: The difference between ball valve q41f46-16c and q41f46-16
- Q valve Code: ball valve;Drive mode: manual, no code;4 connection: flange connection;1 structure form: floating through type;F46 sealing material: lining fluorine;16 valve original pressure: 1.6Mpa 16 kgC body material: Cast Steel
