Q:Replacement method of PPR hot melt ball valve
The above problems belong to the wire type, and the name is: double live catch valve, directly loosen the lock nut, replace the valve can be.When the valve is purchased, the merchant sells a full valve. When the change is made, both ends of the live joint lock nut are removed and the valve is directly connected with the original lock nut on the pipe.
Q:Why is there a water or oil in the new ball valve?
Forged steel ball valve installation will add butter to prevent damage to the seal, test pressure, if you use the water test pressure, generally will remain some of the normal
Q:Gate valve, butterfly valve, ball valve advantages and disadvantages? What other commonly used valves?
Commonly used valves are: gate valve, globe valve, check valve, ball valve, butterfly valve, safety valve, regulating valve, plug valve and so onValve: valve is closed parts (RAM) vertical movement of the valve in the pipeline along the channel axis, used primarily as a medium cut that open and close use. In general, the valve can not be used as a regulation flow. The utility model can be applied to low temperature pressure, and can also be applied to high temperature and high pressure, and can be made according to different materials of the valve. But the valve is generally not used to transport mud and other media pipeline.Advantages: fluid resistance is small; the opening and closing torque needed by the smaller; can use the ring pipe flow to the two direction in the medium, that is to say the unrestricted flow of medium; the fully open, the sealing surface by the erosion of the working medium is smaller than the cut-off valve; the body has the advantages of simple structure, manufacturing good craft; the structure of relatively short length.Disadvantages: the size and height on the larger required installation space is larger; in the process of opening and closing, a relative friction sealing, friction is large, even scratch phenomenon caused by easily at high temperature; the valve has two sealing surface, to processing, polishing and maintenance of some increase the opening and closing time difficult.
Q:What is the difference between PPR ball valve and PPR live ball valve?
PPR and PPR union ball valve is different: PPR union ball valves and pipes on both sides (hot melt) connected between, a movable joint (hot melt) and (link with) nut, maintenance, convenient disassembly and replacement of the valve, the union not only cut off the PPR ball, maintenance.
Q:The difference between cut-off valve and ball valve in PPR
The PPR valve is plug shaped valve, sealing surface flat or cone, fluid along the centerline of the valve for linear motion. Stem movement in the form of lifting rod (stem lifting, hand wheel not lifting), but also lifting, rotating rod type (hand wheel with the valve stem to rotate up and down, nut on the valve body). Valve is only applicable to fully open and fully closed, does not allow for adjustment and throttle.Ball valve has compact structure, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, the media can not easily be eroded, easy operation and maintenance for water, solvents, acids, and natural gas general working media, but also applies to poor working conditions of media, such as oxygen, hydrogen peroxide methane and ethylene, etc., are widely used in various industries. Ball valve body can be integrated, or can be combination.
Q:Stainless steel ball valve Q41F-16P DN80 weight is
The whole diameter is about 40kg heavyThere is a slight difference between the manufacturers
Q:What is the service valve?
I said that the pipeline on the pipeline pigging long-distance, pigging requires this launcher equipment, is the pigging ball into the barrel inside, and then through the process so that the pig into the pipeline, detection of pipeline cleaning or other purposes.
Q:What is the specific difference between floating ball valve and fixed ball valve?
Floating ball valves and fixed ball valves can be located in the lower stem position, if there is a lower stem is fixed ball valve
Q:A connection wire for 21mm the other end is connected to 4 points inside the pipe joint ball valve
Four is 1/2=DN15, 21mm data is not accurate, if it is metric thread, provide tooth pitch and thread diameter.
Q:Is the ball valve ball valve?
One is with an eccentric, hemispherical valve most market means. This eccentric semi ball valve disc shaped like a hemisphere valve valve switch trip also is 90 degrees, but the rotation center of the valve (the valve shaft and the valve seat center (body) or line center) with an eccentric, made after the valve opening immediately from the valve seat, the sealing ball valve and the movement principle is not consistent.
