Q: How does ball valve indicate?: Valve type designation method is standard, the landlord himself to check the JB/T308 standard, Baidu library some, and is free to download:JB/T 308-2004 valve type method of preparation clear Edition

Q: What does the RTFE say in the ball valve?: RTFE reinforced PTFE is more wearable than PTFETeflon PTFEThe seat of tetrafluoroethylene specified for a temperature range of ~200 DEG C -32. High temperature resistance and chemical resistance. Because of its high density and good permeability, PTFE can also prevent the corrosion of most chemical media.Conductive PTFE is an improved PTFE product that allows the current to pass through the lining and thereby cancel the insulation properties of ptfe. Because of its conductivity, conductive PTFE can not be checked by edm.+ reinforced PTFE RTFERTFE is a modification of PTFE material. Pure PTFE although very low coefficient of friction (0.02~0.04) but the wear volume is great, but also because of its easy creep, poor mechanical properties, low bearing capacity, poor dimensional stability characteristics such as friction material has great localization. Only modified by compound method to meet the special requirements of all walks of life sealing material on the wear resistance, to improve the wear resistance of PTFE, can be incorporated into some wear-resistant materials such as glass fiber, carbon fiber, graphite, molybdenum disulfide, bronze powder and some organic compounds, making them reticular junction formed in the PTFE layered structure so as to improve the the stiffness, thermal conductivity, creep resistance, and greatly improve the wear resistance.PTFE is composed of tetrafluoroethylene monomer polymerization of the polymer, the wax is similar to a PE transparent or opaque, its density is 2.2g/cm3, the water absorption rate of less than 0.01%. Its chemical structure is similar to that of PE, except that all hydrogen atoms in polyethylene are replaced by fluorine atoms. Because the C-F bond is high and stable in performance, it has excellent chemical resistance

Q: Flange ball valve Q41P3-150C2, DN50, RF, WCB/316 hardening, each letter number represents what?: P3, C2? Uncultured, I know P and C, P is the sealing surface material boroning steel is above C, WCB or A105But you Tidianyijian pressure 15MPa, RF surface is not well, the best is to use RJ flange

Q: What are the inside parts of the ball valve?: The ball valve consists of a ball, stem, valve seat, upper bearing, lower bearing, spring and valve body.

Q: What are the types of vacuum ball valves?: Shanghai Guardian valve has the production of GUD type electric high vacuum ball valve, GU manual high vacuum ball valve, GUQ pneumatic high vacuum ball valve, welcome to buy, thank you!The utility model has the advantages of simple structure, good tightness, small installation dimension, small driving moment, simple operation and rapid opening and closing

Q: What is the diameter of the 2 inch ball valve?: 2 inch ball valve, diameter is two inches.Turn left and turn right |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 to rotate the valve movement. 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.Turn left and turn right |The answer is recommended by He Xiaoqiang, a member of the science education category

Q: What's the advantage of using an electric ball valve?: Shanghai power code solenoid valve on the official website introduced the benefits of four point electric ball valve, 1. for two cutting, adjusting the occasion. 2., electric ball valve can be achieved on the petroleum, chemical, paper, metallurgy, sewage treatment, oil tanks and other transport pipeline cutting off the medium and circulation. 3., good sealing performance, large flow capacity, convenient handling and maintenance, small flow resistance, reliable sealing, and even cut off. 4. 、 electric valve is small, light weight, big thrust, powerful function, servo amplifier built-in, easy to operate, high reliability.

Q: The two valves are available for the flow of the electromagnetic valve switch, I contact more, found for water solenoid valve are caged water, to repair several times because of impurities or newly installed pipeline with raw materials flowing through the valve, close the valve body when not to rely on Yan, a seepage water tank to diffuse phenomenon!I am looking for a replacement, I think the electric valve should be a good choice, not used to a conclusion.Please use the electric ball valve to talk about friends, or for the two kinds of friends who have an understanding to talk aboutOr there is no better substituteThere seems to control the solenoid valve and electric valve is not the same, the solenoid valve is normally open and closed to control the electric valve is controlled by the trigger (like), if used to replace it, what is the controller?: I think you should use the solenoid valve is diaphragm type, and not particularly good products, diaphragm solenoid valve in the closed position when the diaphragm is easy to change, resulting in pipe die, or medium impurities caused the pilot hole is blocked, the valve will not move, so the diaphragm solenoid valve. Is there a film guide card member, so that each position of the diaphragm in the correct position, but the pilot hole is not a solution, of course, you can use direct action solenoid valve, such problems are solved. The electric ball valve than the pilot solenoid valve in this respect, but the cost of this fear is much higher, especially the pipe diameter is not so, it does not pay!

Q: What are the use of all - way ball valves and reducing ball valves respectively? What are the advantages?: But for the need for regular pigging of the pipeline, no matter what medium to transport, you must use full diameter ball valve.

Q: Water heater ball valve is not very easy to pull, why does it feel bad?: Use the hair dryer, hot air gear to blow for a while, slowly screw, a bit loose, continue to screw, you can completely screw, and more than a few twists and turns, long time does not move, it will be stuck
