Q:Comparison of foreign valves, such as Jiang Sen, SIEMENS, Honeywell, Watts, Tyco valves?
Tyco doesn't know much about it. It's often written in the bidding documents, but there are very few actual purchases, so I don't evaluate it any more. The strongest of the balance valves is the TA (Swedish). He was the originator of the balancing valve. Super high-rise complex, the hotel part, you mention these kinds of valves are applied a lot.
Q:What does the J41Y-100I valve type mean?
Stop valve typeJ represents the cut-off valve, 4 (flange) on behalf of his connections, 1 (straight) on behalf of his structure, Y (seal) on behalf of his seat sealing surface or liner material code, 100 is the nominal pressure value, I (chrome molybdenum steel) is the code of the body material
Q:Which valves are installed in a directional manner?
Very simple answer to your valve, in addition to gate valve and butterfly valve (single line up, first closed), such valves are not directional, and other have
Q:How to better maintain the valve?
We should keep the valve cleanWe should regularly check and maintain the integrity of the valve the other components. As a fixed hand wheel nut fell off, to be filled and can not manage, otherwise it will grind the valve stem upper garden square, gradually lost with the reliability, and even can not startWe do not rely on the valve support other heavy objects, do not stand in the valveThe stem, especially the threaded part, to regular cleaning, the dust has been soiled should be replaced with a new lubricant, because the dust contains hard debris, easy to wear thread and stem surface, affect the service life
Q:How does the valve open?
This is a three pass, not a valve. It doesn't open often or often closes and there is no opening or closing. Can change the same caliber of the valve, you can use the handle switch.
Q:Chinese valve and a valve which is better?
Look what valve you use, ah, these two can be ah!
Q:Why can't the clip type check valve be directly connected with the pipe mouth or other valves?
The clip type check valve is made up of two discs to prevent backflow.If the clip check valve is connected to the other valve, the disc may touch the valve and cause the check valve not to be fully opened or closed. This is a preliminary analysis of "enter the valve", for reference only!
Q:What is the purpose of the valve?
Valve is a pipe accessory. It is a device used to change the direction of the passage and the direction of the medium flow, and to control the flow of the conveying medium.Valves have the following uses:1. Connect or cut off the medium in the pipe. Such as gate valve, globe valve, ball valve, plug valve, diaphragm valve, butterfly valve and so on.2 、 adjust and control the flow and pressure of the medium in the pipeline. Such as throttle, control valve, pressure reducing valve, safety valve, etc..
Q:Why is copper used in cryogenic valves?
Copper, which is rarely available, is easily deformed at low temperatures and is much more WCB or WCC.Below -46 degrees C, SA352, LCB.LCC
Q:What is the normal temperature on the valve?
What's the valve?. Conventional valves are 425 degreesIf it's on the oil field. It's only 120 degreesAt normal temperatures are below 120 degrees. A lot of valve sealing surface can only reach 120 degrees
