Q:Are ordinary ball valves standard?
Not counted. 3/4 is also called DN20, also called 6 points.DN20, that is to say, the caliber is 2 centimeters, so you see?.
Q:Buy Ball Valves
You take this valve to the building materials market, see the valve handle can be sheathed in your valve stem, the valve handle is arranged to buy, your valve
Q:Q4110 what is the ball valve? What does each number stand for?
It's Q41-10Q- stands for ball valves; 4- stands for connecting flanges; 1- is straight through floating ball; 10 means valve bore 10If it's Q4110, you're not sure
Q:Structure design principle of fire ball valve
The purpose of fire protection structure design of valve seat is:(1) effective guarantee in the fire accident, the upstream pressure medium as little as possible into the body cavity through the valve seat, thereby causing internal leakage and leakage. Ensure that fire accidents are not expanded by fire before the firemen arrive at the scene of the accident. After the firemen arrive at the scene, fire equipment can be used to quickly suppress the fire and eliminate fire accidents.(2) to make the structure of the product meets API6D specifications. Fire proof can be obtained through fire test.Fireproof design of valve seat:Set graphite in metal fire valve seat and valve body sealing rings; sealing set fireproof metal in the metal valve seat and ball room. The structure is shown in Figures 1 and 2.
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: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:DN80/DN100/DN125 how big is the outer diameter of the ball valve flange?
In addition to the three common, flange standard complex, a long story.All kinds of standards, there is a little difference in thickness, diameter of flange, bolt hole number, but the flange bolt hole parameters of the same pressure level (bolt circle diameter K, bolt diameter L, bolt number N) are the same.
Q:DN15 ball valve with a bit of outer wire
Is. But we usually use engineering diameter in our country. A few is the imperial system, in addition to the domestic veteran workers still use, and now are using GB size.
Q:What's the diameter of the 4 point ball valve?
"4 point ball" in the "4 points" is based on the length of units per inch evolved;Divide 1 inches (25.4mm) 8, 4 points 4/8, or 1/2 inches, equal to 12.7mm.Therefore, "4 points ball valve" diameter is 12.7mm.
Q:A connection wire for 21mm the other end is connected to 4 points inside the pipe joint ball valve
DN20 is not the ball valve, 4 points that the size of the head with 20*15 change
