Q:Where is it installed, what is the role, what is the material, and are there other alternatives instead of this effect?
Valve packing in the valve under the gland to prevent leakage, you can use ordinary asbestos rope and butter emergency replacement
Q:Where is the Shandong valve? How about joint valves in Shandong?
To find Shandong valve manufacturers, Shandong better valve manufacturers are in Weifang, find the valve factory is also simple, direct search "Weifang valve" is
Q:How can you replace the other valve when the main valve is not closed and no water is stopped?
You really want to go to the big water to fix the valve and be prepared for the follow-up, just in case
Q:What is the diameter of a general pipe valve?
In fact, the essence of the problem is the corresponding relationship between the nominal diameter and other dimensioning methods. Valves are generally marked with nominal diameter (DN***), such as DN150, DN100 and so on. There are many kinds of marking methods for pipes, such as outer diameter, inch inch, nominal diameter, etc.. Only when the other dimensioning is converted to nominal diameter, the valve and the pipe correspond to each other.
Q:Air compressor out of the gas with what kind of valve control okay, globe valve or other?
Air compressor all copper safety valve (AQ-20) (AQ-25)Air compressor, air release valve and so on. The air compressor rated exhaust pressure is divided into low pressure (0.7~1.0MPa), medium pressure (1.0~10MPa), high pressure (10~100MPa) and ultra high pressure (100MPa or more), to see what kind of installation you are and use
Q:Where is the filling portion of the valve?
The middle of the screw down valve handwheel saw packing gland generally about two screws fixed or fixed on the pressure cap down is the appearance of the packing is not seen inside if leakage occurs usually filler filler fastening screws, general pressure valves are graphite filler
Q:1) the valve plate, valve gate valve, the difference (my personal understanding is that if it is on the ball, called the valve, if the valve is called the gate, is actually a meaning in different valve called, please help me understand it right?)2) valve clack. What's the spool?3) the valve seat is welded inside the valve, or is it directly installed inside without welding?4) when opening the valve, if the valve seat is not welded, then, under the pressure of the medium, why not open the seat?.5) excuse me, pressure self sealing (my personal understanding is that when the valve is closed, the valve plate and valve seat depend on the pressure of the media, and they fit together to seal the effect
The first question is basically the same, and you can understand that for the secondThe 3,4 problem, there are several seat connections, such as thread connection (threaded, the valve seat is connected with the valve), modular connection (such as adding the cage to a fixed seat, the crushed) as one of the body and there is (some welding). The valve seat must be fixed.The fifth question, you are right!
Q:Valve connections - two how do different connections work?
The connection of two different connection forms is achieved by a transition conversion connector
Q:What does the whole copper valve mean?
The whole valve is made of copper material. In addition to the ceramic core.
Q:What is the difference between the valve before the pump and the valve after the pump?
Pump front valve: current limit; pump rear valve: limit pressure.Pump operating procedures: the pump must be closed before and after the valve, open the pump, slowly open the pump front valve, pump pressure normal, slowly open the pump, valve until all open. If the pump is in front and rear valves are opened, the pump is very easy to burn the motor.
