Q:What are the uses and characteristics of copper ball valves?

4, good sealing performance5, the direction of installation is not limited, the flow of media can be arbitrary

Q:What does 1000WOG mean on a ball screw valve?

A unit of pressure. WOG is the initial letter of water, oil, and steam. It represents the water, oil, and gas pressure passed by 1000 pounds per square inch.Converted to kg: 1000*0.07*9.8/100=68.6KG

Q:Please professional help guide: accidental discovery of connection pipe and valve (mark position diagram) can rotate, but there is no problem with the 10 Water Leakage.Please professional help guide: accidental discovery of connection pipe and valve (mark position diagram) can rotate, but there is no Water Leakage problem, while the valve under the same position is fixed and can not rotate, will this situation is normal? Is it possible to leak water in the future?

Abnormal, should be fixed, a long time may leak.

Q:What does the sealing surface of the ball valve stand for HF?

HF is the abbreviation of two English words: "Hard Face", which means surface hardening. Usually surfacing is made of Tailai alloy (Alloy 6). Other surface hardening methods include hard chromium plating. This method is used more in the ball valve. But hard chromium plating is prone to small cracks, which reduces its corrosion resistance.

Q:For the master enlighten Q47 ball seat spring hole number is determined by how

Force = spring stiffness (kg/mm) * compression volume (mm)Number of work cycles of spring stiffness = line diameter *1000/C 3 timesC= spring middle diameter / line diameterSpring diameter = spring outside diameter line diameterCalculate each spring force, multiplied by the number. According to the manual valve design must be greater than the pressure, pressure ratio must be large than the material allowable pressure on the line. (emphasize that here because the production process of the spring, has value of many uncertain factors, so the actual production of the spring and you cannot calculate out the same, so please choose when to consider).

Q:To help explain the meaning of the ball valve Q11H-16H, combined with the actual, such valves have wood?

JB T308-2004 valve model preparation method and "GB1048-2005 pipe element nominal pressure definition and selection", there are various types of valve interpretation:Q11H-16HQ: valve type: (Q) ball valve1: connection form: (1) internal thread1: structure form: (1) through flow channelH: sealing surface or lining material: (H) Cr13 stainless steel16: pressure code: (16) 1.6MPaH: body material: (H) Cr13 stainless steel

Q:DN20 pressure 6000PSI, one piece of thread on the threaded, full diameter ball valve body length and flow hole to how much?

3, the flange of the same caliber and cavity size, the premise is to ensure the gate open without collision resistance, but the size and thickness of screw and the number can be determined with reference to the parameters of the same diameter flange. Finally, the point is that in mechanical design, as long as the design is reasonable, there is nothing right or wrong, but it is possible that a design will be more appropriate.

Q:Our factory has part of the ball valve in the direction of movement and normal ball valve is the opposite direction: anti clockwise for the turn off, clockwise. Excuse me, what's the reason for this?Excuse me, is this because the valve body installs the reason of the contrary or the reason, the ball valve is thus designed?Are there any positive and negative points when the ball valve is installed?

Ball valve is 90 degrees switch, you may put the handle of the wrong position, change 90 degrees, try it

Q:What are the applicable conditions of ball valves?

Ball valve is also suitable for light structure, low pressure cut-off (small pressure), corrosive medium piping system. Ball valves can be used in cryogenic (cryogenic) units and piping systems. In the oxygen pipeline system of metallurgical industry, ball valve with strict degreasing treatment should be used. The main line in the oil pipeline and gas pipeline shall be buried in the ground, and all pass welding type ball valves shall be used. The ball valve with a V shape opening shall be used when required to adjust the performance. In the petroleum, petrochemical, chemical, electric power and urban construction, the piping system with working temperature above 200 degrees can choose metal to metal sealed ball valve.
