Ball valve, ball valve in the field of Marine engineering and ship should stop valve), the standard of GB/T21465-2008 "valve terms" is defined as: opening and closing (sphere) driven by the valve stem, and around the axis of rotation movement of the valve stem.Use can also be used on regulation and control of fluid, the "V" ball valve, hard seal the v-shaped ball core of carbide surfacing with strong shear force between metal valve seat, especially suitable for fiber, micro solid material such as medium.And ball valve in the pipeline is not only more connected to the confluence of flexible control medium, shunt, and the flow switch, at the same time also can close any channel and make the other two.This valve shall generally be installed in the pipeline.Classification of ball valve, pneumatic ball valves, electric ball valves, manual ball valve.

Q: Replacement method of PPR hot melt ball valve: 2, if the valve is directly welded on the pipeline, you need to stop the operation of pipeline, and cutting, the need to replace the valve flange or screw type ball valve, ball valve flange need two "steel plastic adapter" heat welding with the original pipe, the flange type ball valve can be installed; the screw type two single head, a head and pipe welding / bonding, joint head and ball valve with wire of threaded connection.

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: What brand of double live catch valve is good?: Different brands of PPR products can be connected, but in order to facilitate after-sales service, it is best to choose the same brand products.

Q: Gate valve, butterfly valve, ball valve advantages and disadvantages? What other commonly used valves?: Commonly used valves are: gate valve, globe valve, check valve, ball valve, butterfly valve, safety valve, regulating valve, plug valve and so onValve: valve is closed parts (RAM) vertical movement of the valve in the pipeline along the channel axis, used primarily as a medium cut that open and close use. In general, the valve can not be used as a regulation flow. The utility model can be applied to low temperature pressure, and can also be applied to high temperature and high pressure, and can be made according to different materials of the valve. But the valve is generally not used to transport mud and other media pipeline.Advantages: fluid resistance is small; the opening and closing torque needed by the smaller; can use the ring pipe flow to the two direction in the medium, that is to say the unrestricted flow of medium; the fully open, the sealing surface by the erosion of the working medium is smaller than the cut-off valve; the body has the advantages of simple structure, manufacturing good craft; the structure of relatively short length.Disadvantages: the size and height on the larger required installation space is larger; in the process of opening and closing, a relative friction sealing, friction is large, even scratch phenomenon caused by easily at high temperature; the valve has two sealing surface, to processing, polishing and maintenance of some increase the opening and closing time difficult.

Q: Can the ball valves be used in heating?: Heating can be used.Ball valve (ball valve), standard GB/T21465-2008 "valve terminology" is defined as: "open and close parts (spheres) driven by the stem, and around the axis of the ball valve 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.

Q: The hot water pipe ball valve what brand alone?: Such as the bathroom taps are generally alternating hot and cold water, will be pulled out from the faucet two hoses, and then connected to the wall, embedded in the wall of the interface is angle valve. Because the heating pipe at the corner of the shape of 90 degrees angle, and the ball valve is straight through, so the basic difference between angle valve and spherical valve is that the angle valve exports and imports into 90 degrees right angle. rn usually angle valve mainly plays four roles: rn transfer within rn out nozzle; when the water pressure is too large, can be adjusted in the triangle valve above, turn down; the rn with switch function, if the leading Water Leakage phenomenon, can promptly put the triangle valve off, instead of the total valve closed in the home.

Q: What does "DN PN" mean? DN25 PN18 stands for what is the thickness? With the usual said 4 in charge of what's the relationship?: PN nominal pressure.Definition：Relating to the mechanical and dimensional characteristics of the components of the piping system and the identification of letters and combinations of numbers for reference. It consists of letters PN and followed by dimensionless numbers.Note 1: numbers followed by letters "PN" do not represent measurements and are not used for purposes of calculation unless otherwise specified in the relevant standards.Note 2: is not associated with the relevant pipe component standards, but the term "PN" does not make sense.Note the 3: piping element allows the pressure to depend on the PN value of the element, the material and design, and allows the operating temperature, etc., to allow the pressure to be given in the corresponding standard pressure temperature class table.Note 4: all pipe elements with the same PN and DN values shall have the same mating dimensions as their flanges.The latest definition of PN comes from standard GB/T 1048-2005, the definition and selection of pipe component PN (nominal pressure), and is referenced in the standard of pipe fittings and tubing. GB/T 1048-2005 7268:1996 Pipe components - modified ISO/CD Definition of nominal pressure, a "note increase than the original standard: allow numerical" choose other PN when necessary, namely in the PN series, you can use other numerical PN.

Q: What are the types of vacuum ball valves?: The utility model can be used in the high vacuum condition and can be used under the low voltage system, and the advantages of positive and negative pressure are same

Q: What are the structural shapes of the eccentric hemisphere valve, what are their respective characteristics?: I. structural form:The eccentric hemisphere valve is divided into two kinds in its appearance and structure:The coat type: mainly for erosion is very serious in the medium, upper structure replaced maintenance loss of the opening and closing member is very convenient, without the whole valve removed from the pipeline, greatly saves the maintenance time and cost.Side mounted: side mounted, compact structure, light quality valve, applicable to the valve installation space requirements.

Q: Three electric ball valve type T and type L what is the difference?: Ball valve: including straight through, three, etc.. Three way ball valve: including L type, T type. Therefore, the three way ball valve is a kind of ball valve! But the regular ball valve means straight through.
