Underground Full Welded Ball Valve

Q: How many kinds of ball valves are there?: Ball valves (ball valve in the field of marine engineering and ships should be cut-off 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 to rotate the valve movement.".

Q: PPR ball valve which face is open, which face is closed, there is a o, there is a s, which is off, ah, which is open, well intentioned people told me that the original finished by forget: Hello, I am glad to answer for you. O is on, s is off. I hope I can help you.

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: 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: For our valve beginners, how intuitive decision is floating ball valve or fixed ball valve?: Floating ball valves and fixed ball valves can be located in the lower stem position, if there is a lower stem is fixed ball valve

Q: What is the nominal pressure 1.6p of a ball valve?: Nominal pressure: reference value relating to the pressure resistance of a piping system. For ease of use, usually the priority of the R10 series is taken. Nominal pressure refers to the pipe in the two temperature (20 degrees Celsius) when the water delivery pressure. If the water temperature is between 25 and -45 degrees, the coefficient of temperature drop should be adjusted to correct the working pressure.

Q: I design water meter transformation, 50WPD table, the original table before the installation of 50 anti-theft valve, table after the installation of 50 of the globe valve; master let me put anti-theft valve into anti-theft gate valve. Switch the stop valve to the gate valve. I'd like to ask what kind of valve is appropriate Why? And I checked from the Internet that the ball valve is generally used for small aperture, this aperture range is how much? Why?No copy paste, thank you......: Ball valve and valve are generally used for fluid switching and flow, usually can not be used for flow regulation, and in addition to the valve can be used for fluid switching and cut-off, can also be used for flow regulation. If you need to adjust the flow rate, it is better to use the medium valve. The valve operation is very convenient, rapid and labor-saving, generally as long as the valve handle can turn 90 degrees, and the ball can be used not too pure (solid particles) fluid because of its spherical valve core of the fluid in the opening and closing of the shear movement. The gate seal between easy to cause erosion and abrasions, maintenance more difficult, larger size, open need a certain space, opening and closing time is long, complex structure.As you say, the ball valve is generally used for small caliber, because small caliber production is simple, relatively inexpensive, caliber increased production accuracy requirements, production costs increased, so the price will be high. Generally small diameter threaded connections, from the G1/4~G2 have.

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 are the applicable conditions of ball valves?: Ball valve is also suitable for light structure, low pressure cut-off (small pressure), corrosive medium piping system. Ball valves can be used in cryogenic (cryogenic) units and piping systems. In the oxygen pipeline system of metallurgical industry, ball valve with strict degreasing treatment should be used. The main line in the oil pipeline and gas pipeline shall be buried in the ground, and all pass welding type ball valves shall be used. The ball valve with a V shape opening shall be used when required to adjust the performance. In the petroleum, petrochemical, chemical, electric power and urban construction, the piping system with working temperature above 200 degrees can choose metal to metal sealed ball valve.
