Q:Ball valves, butterfly valves, gate valves, stop valves, check valves, etc., are used where ah?
Q:PP-R double joint hot melt copper ball valve DN50 connection method how to connect?
Use hot melt way to weld, use special PPR hot melt machine.PPR hot melt machine, also called heat sealing device, sealing machine, etc.. For heating docking PPR tubes.Suitable for heating butt PPR tubes. Simple and practical, small price around 30RMB.
Q:What's the difference between a ball valve and a butterfly valve? Which one has better sealing performance?
The structure of valve and butterfly valve, and determines the price of the different use of the environment. The same nominal diameter of the butterfly valve and ball valve has the advantages of simple structure, low cost, adjustable range, liquid and gas valve is usually applied to non particulate impurities like fluid, small pressure loss, good sealing performance, high cost. Generally speaking: small caliber election ball valve, large caliber butterfly valve.
Q:What's the difference between T ball valve and L ball valve?
This is the code for the three way ball valve and the three way plug valve flow passage. The L shape can only connect the two channels perpendicular to each other, and the T shape allows the three channels to communicate with each other or to connect two of them.
Q:3/4 on the elbow of the water pipe. How about that ball valve?
3/4 inches converted approximately equal to 20mm, that is, DN20, can be equipped with DN20 caliber ball valve, commonly used for brass material
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:For the master enlighten Q47 ball seat spring hole number is determined by how
Force = spring stiffness (kg/mm) * compression volume (mm)Number of work cycles of spring stiffness = line diameter *1000/C 3 timesC= spring middle diameter / line diameterSpring diameter = spring outside diameter line diameterCalculate each spring force, multiplied by the number. According to the manual valve design must be greater than the pressure, pressure ratio must be large than the material allowable pressure on the line. (emphasize that here because the production process of the spring, has value of many uncertain factors, so the actual production of the spring and you cannot calculate out the same, so please choose when to consider).
Q:Hard sealing ball valve, what method can calculate the leakage?
Valve leakage level is used as an important reference standard in valve leakage test.Usually in accordance with the requirements of the process. In the process of lifting the conditions and processes, there will be valve leakage level requirements.
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:Where to buy the ball valve?
Use less to the local hardware market, use more direct to find a company to buy
