Q:What is the difference between ball valve and butterfly valve?
The butterfly valve consists of valve body, valve seat, valve plate, valve rod, all parts are a significant drain on the outside, one eye can see; and the ball valve is composed of a valve body, the valve core (a round ball), valve rod, valve position is in the valve body inside, the naked eye can see only a part, so the sealing performance of the ball valve than the butterfly valve; butterfly valve structure is relatively simple, generally with low pressure valve, high pressure valve can reach 64 kg. The ball valve structure is relatively complex, more resistant to high pressure, the ball valve up to 100 kg.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 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; the valve can also be divided into soft seal and seal, soft seal valve maximum temperature is below 280 degrees, the pressure is on 64 kg, hard seal ball valve temperature can reach 425 degrees below the pressure below 100 kilograms. Shanghai Sino US valve for your answer, for reference.
Q:DN20 copper ball valve with large PPR converter connector
What do you see a ball valve, PPR ball valve, ball valve with internal screw threads, ball valves, but if you look at the butt of the ball size, if the ball is 20. The tube is 20, then the 20*1/2 internal thread can be directly on the butt.
Q:Daily maintenance of ball valve
The new parts need to be cleaned before assemblingThe assembly should have metal fragments, fiber, fat is not allowed (except the requirement to use) dust and other impurities, foreign matter contamination, adhesion or remain in part into the cavity on the surface or, if the packing is micro discharge, to lock the stem nut.Note: do not lock too tight, usually lock 1/4 circle to 1 laps, the leak will stop.(A) disassemblyMake the valve in a half open position, flush and remove dangerous substances that may exist inside and outside the valve body.Close the ball valve, remove the connecting bolts and nuts on both sides of the flange, and then remove the valve completely from the line.In order to remove the drive - actuator, a connecting bracket, lock washer, stem nut, butterfly spring, glam, wear plates, valve stem packing.Remove the body cap connecting bolts and nuts, separate the valve cover from the valve body and take off the valve cover washer.Make sure the ball is in the "off" position, which can be easily removed from the valve body and then removed from the valve seat.A hole in the body downward nudge stem until completely removed, and then remove the packing ring and the O.Caution: Please operate carefully to avoid galling, stem surfaces and body packing box seals.B) reassembleCleaning and inspection of the parts removed, it is strongly recommended to use spare parts package replacement valve seat and valve cover, gaskets and other seals.Assemble in reverse order of disassembly.Cross the locking flange bolts with the specified torque.Lock the stem nut with the specified torque.
Q:What does "q41f46-16c-dn40" mean?
DN40 refers to the nominal diameter, 16C represents 16 kg of pressure, carbon steel material F46 stands for fluorine
Q:What are the types of vacuum ball valves?
Vacuum ball valve refers to the work pressure is lower than the standard atmospheric pressure, forming a certain vacuum ball valveVacuum ball valve models are GUD, GDQ, KF16, GU, KF and so onVacuum ball valve type has electric, manual, pneumatic, such as GU manual vacuum ball valve
Q:What are the uses and characteristics of copper ball valves?
4, good sealing performance5, the direction of installation is not limited, the flow of media can be arbitrary
Q:What does "S" mean by ball valve Q11S?
S is the body material code, plastic.
Q:1 and 1/2 ball valve is how much?
1 and 1/2 ball valves, DN40mm.The ball (ball valve as the cut-off valve in the marine and marine field), standard GB/T21465-2008 "valve terminology" is defined as: opening and closing parts (ball) driven by the stem, and around the valve axis for rotation of the valve. 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. Switch and multi way valve in the pipeline not only can flow, and flow diversion, flexible control of the medium, but also to turn off any channel to the other two channels. This kind of valve should be installed horizontally in the pipeline. In accordance with the way to drive the ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball valve.
Q:What does the sealing surface of the ball valve stand for HF?
HF= hard solder material in valves Q347HF, -16C, welded with CoCr or NiCr alloy.
Q:One stainless steel ball, two pieces, three pieces of difference, use
A piece of ball valve, that is, the principle of Canton style ball valve is to rely on rotary valve to make the valve open or blocked. Valve switch light, small size, can be made large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, the media can not easily be eroded, widely used in various industries.
