Q:How does the valve open?
Now the valve is in a closed state, the general valve on the valve flow direction marked, like you figure on this, flat side perpendicular to the flow channel is closed, parallel to the flow channel is open.
Q:Why use the pump outlet valve to adjust the flow rate?
This is the most widely used method of regulating flow, while protecting pumps and motors. The general classical installation method is as follows: the pump outlet is equipped with a vibration reduction joint, and then a gate valve control switch, and then install a multi-function water pump valve to adjust the flow.
Q:What are the definitions of internal, external and leakage valves?
The leakage within the valve that is the reason of erosion wear medium makes the valve is not closed tightly, even if the valve screw (stem) screwed in place, because there is still a gap between the spool and the valve body, the medium can flow past.
Q:What does the valve QF mean?
Valve type, one of the contents, Q refers to the ball valve, F refers to the F-4 seals.
Q:What does 3/4''mean in the name of the valve?
Valve diameter, that is, we often say 6 points valve, used in English units, with metric units should be DN20.2 points DN84 points DN156 points DN20 (3/4'')1 inches DN251.2 'DN321.5 'DN402 'DN502.5 'DN653 'DN804 'DN1005 'DN1256 'DN1508 'DN20010 'DN25012 'DN300Nominal diameter (nominal, diameter), also known as the average diameter (mean, outside, diameter).The tube is thin from the metal tube, and the outer diameter of the tube is almost the same as the inner diameter of the tube, so the average value of the outer diameter of the tube and the inner diameter of the pipe is called the diameter.Because the units have metric (mm) and British (inch) distinction, there are the following methods of address.1., based on the metric system (mm), called DN (metric unit)2., on the basis of the British system (inch), called NB (inch unit)DN (nominal, diameter)NB (nominal, bore)OD (outside, diameter)4. [case]Galvanized steel pipe DN50, sch 20Galvanized steel pipe "NB2", sch 205., the outer diameter and DN, NB relationship is as follows:------DN (mm), --------NB (inch), -------OD (mm)15-------------- 1/2--------------21.320--------------3/4 --------------26.725-------------- 1, ----------------33.432-------------- 1, 1/4, -----------42.240-------------- 1, 1/2, -----------48.350-------------- 2, -----------60.365-------------- 2, 1/2, -----------73.080-------------- 3, -----------88.9100-------------- 4, ------------114.3125-------------- 5, ------------139.8150-------------- 6, ------------168.3200--------------- 8------------219.1The above data is referenced only in ASTM A53. Please note that there are some differences in external diameter with different specifications.
Q:What does the "XV" valve mean?
XV:X said V is plug valve, said valve body material is chrome molybdenum vanadium steel.
Q:Heating pipes, in addition to the living room,
There is gas, causing water not to cycle, give up on the cure! Are you single family control?Single family control, the general bedroom and living room is not all the way, the living room, this way, the vent valve in the toilet, I was on the road in the balcony! The bleeder valve, is made of copper tube in the device above two, as long as can step in his place, the bleeder valve with a small angle, feet above a needle, with a needle to drill a well, there is a long time not float, a gas exhaust out that leads to water circulation,Why do you put a little while, the water is hot, a little cooler, the water does not cycle, is dead water, can not cool it?I am building plumbing, believe me, yes, these are some common problems, especially on the top floor!
Q:What does valve J41H-16C mean?
J- stop valve4- flange type connection1- structure typeH- alloy steel seal16- nominal pressure 16 kgC- body carbon steel
Q:What is the difference between low pressure valves and medium pressure valves and high pressure valves?
According to the GB standard test pressure GB/T13927, "industrial valve pressure test" valve in accordance with the pressure can generally be divided into the following categories:(1) vacuum valve: refers to the working pressure is lower than the standard atmospheric pressure valve.(2): refers to the low pressure valve nominal pressure PN valve is less than 1.6Mpa.(3) medium pressure valve: refers to the nominal pressure of 2.5Mpa, PN, 4.0Mpa, 6.4Mpa valve.(4) high pressure valve: refers to the pressure valve PN 10.0Mpa 80.0Mpa valve.(5) super high pressure valve: nominal pressure PN = 100.0Mpa valve.Normally the stresses are actually pressure (force per unit area). Is generally used to gauge our living environment under 1 standard atmospheric pressure as reference 0 (reference point 0), and the difference between the value of the gauge (pressure gauge usually display is the gauge). But in fact we live in 1 atmospheric environment, coupled with the income of the 1 gauge pressure value is the absolute value of pressure.Standard atmospheric pressure actually has standard engineering atmospheric pressure at (kgf/cm2) and standard physics atmospheric pressure ATM, the former used in the early years, and now generally use the latter. 1atm=1.0332at=1.01325bar (bar) =101.325kPa=0.101325MPa.The valve pressure mainly focus on two parameters: rated working pressure, such as PN16, said the rated working pressure is 16bar (1.6MPa); the maximum permissible pressure difference (this value, the greater the actuator thrust torque required with the larger).
Q:What does the "PN" mark on the valve mean?
The valve will usually be marked with "DN.PN." these two signs,DN refers to the valve path, and PN refers to the pressure levelFor example: DN25, PN16Refers to the valve diameter of 25mm valve, the pressure is 16 kg (1.6Mpa)
