2.Feature
1, the slip joint consists of ontology, the short tube, pressure and sealing ring, bolt and force of pressure.
2, general installation on the upstream side of the valve or other device. The slip joint for pipe flanges, upstream of downstream of valve. The slip joint force stud were deeper than the back of the companion flange, pipeline companion flange and valve through the nut, for the connection of tube and valve upstream and downstream equipment.
3, need to remove the valve, to force no lag bolt end flange pipe (side) of the nut loose behind the companion flange, then stretched to shorten the tube on the side of the nut to loosen the flange pipe direction. And then fixed through stud square head, rotate the nut on the reverse of the expansion pipe companion flange, make the move to the telescopic pipe flange pipe end. In the event of a reasonable interval can be removed after. Then unscrew all force stud on all nuts, make force bolt from one side to unload. Remove the valve.

- Q: Remove the handle and lever the stem rotation with a wrench,
- First you know what valve you need, or you know where to use the pipe material, so you do not need to understand the valve material.
- Q: Where is the hydrant main valve?
- The intake valve of the upper and lower ring pipes of the riser of the fire hydrant is generally located at the highest and lowest floors.The general use of the valve rod flange gate valve.Hydrants, officially called fire hydrants, are a type of fixed fire fighting facilities, which control fuel, insulate fire and eliminate fire. Indoor fire hydrant and outdoor hydrant. The fire fighting system includes outdoor fire hydrant system, indoor fire hydrant system, fire extinguisher system, and some automatic sprinkler system, water gun system, gas fire extinguishing system, fire detection system, water mist system and so on. Fire hydrant mainly for fire engines from the municipal water supply network or outdoor fire water network to implement fire fighting, can also be directly connected to the hose, water gun fire extinguishing. Therefore, indoor and outdoor fire hydrant system is also one of the important fire fighting facilities.
- Q: Symbols for all types of valves
- In addition to the throttle valve (L) valve (H) valve (U) valve (Y) of the four types of valves, the other is according to the first letter of the easy to remember the four valve but also second word the first letter and the other valve is repeated with the first letter of a very good record I was just valve knowledge I hope to help you!
- Q: Look at the flow chart, some of the valves are marked with FV, and some are marked with XV. What does that mean?And what do you mean by the Cv value on the valve nameplate?I hope the heroes give a clear explanation ah, it is best to give an introduction of this knowledge of the web site oh.Thank again.
- FV or LV on the flow chart, which represents the instrument bit number, FV is flow valve, and LV is level valve.The valve on the nameplate CV value, it is a measure of the size of the valve flow, it is the concept of 40 - 60 degrees Fahrenheit in the water, the pressure drop of 1 psi, in a valve opening per minute flow through the valve (U.S. gallons).
- Q: What's the name of the valve?
- This is not a valve, it is a pipe bender.
- Q: What are the technical requirements of valves, such as "Z15W-25T"?
- Z = gate valve1 = internal thread connection5 = dark rod type (structural form)W = body seal payments25 = 2.5MPa (nominal pressure)T = copper (body material)Landlord can refer to JB/T 308-2004 valve model preparation methods
- Q: What do you mean by the 16 bit coding of the valve type?
- Not regular encoding. Regular encoding is usually 11 bit and sometimes 13-14 bit
- Q: What's the difference between a valve and a valve?
- The correct unit should be called "group". A set of threaded valves include valves, live connections, and short tubes. A set of flanged valves consist of a pair of flanges (including bolts, gaskets, rubber pads), and short tubes".
- Q: What is the term "Z41H-16C" on the line?
- When Z41H-16C opens the valve, when the gate lift height is equal to 1:1 times the valve path, the passage of the fluid is completely unblocked, but at run time, this position is not monitored. In actual use, the top of the stem is used as a sign, i.e., the open position, as its fully open position. Temperature changes appear to consider locking phenomenon, usually open to the vertex position, and then rewind 1/2 1 circle, as a fully open valve position.
