Q:What does the valve stroke mean?

The distance from one position to another. Usually in the first position of the cut position, the second position is put through the position. Unless the valve has 3 positions.[1] to determine the stroke of the valve is the valve and valve two, closing stroke of its opening height, the valve opening height to diameter of the valve is fully open, 1/3, so the opening height is part size below the path + gate is closed.[2] valve: valve (Famen) is a fluid conveying system control components, with a cut-off, regulation, diversion, to prevent reverse flow, voltage regulation, shunt or overflow, pressure relief and other functions. Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..

Q:How to check the quality of the valve?

First of all, to check the appearance of the valve is smooth and smooth. Cast valves without sand holes and obvious flaws. Forged valves check nominal pressure or pound level.Second, check the material of the valve, that is, the material composition, this is very important, the material does not meet the standard on the device will be a big problem.Finally, check that the switch is sensitive and the signs are clear. Test pressure is the last step.Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..

Q:Which industries need valves?

Valve as a general component, widely used in various industries, but there are three main purpose of application in various industries:1, routine inspection needs;2, new projects supporting;3, emergency reserves.Valve market trendsDue to changes in user demand, the market trend of valve products will also change accordingly. In the future, the main trends are as follows:1 with the transfer of oil development to the mainland oil fields and offshore oil fields, and the power industry under the 300 thousand kilowatts of thermal power to more than 300 thousand kilowatts of thermal power and hydropower and nuclear power development, and valves should be changed based on device applications and the corresponding changes in its performance and parameters;2 urban systems generally use a large number of low-pressure valve, and to the development of environmentally friendly and energy-saving, low iron gate that is used in the past gradually shifted the environment-friendly plastic sheet valve, balance valve, metal sealed butterfly valve and the center line butterfly valve seal transition, oil and gas pipeline projects to develop in the direction, which in turn requires a large number of flat gate valve and ball valve the;

Q:Can the gas valves be switched off regularly?

The small valve called skin stopcocks, his design is often switch, but for the sake of safety, natural gas company also installed a lock valve in front, once the leak immediately close the valve, the valve once closed to find a Gas Co came to open, so it is not necessary the case don't go off.What we usually need to pay attention to is..:1, every time you finish cooking, you must close the pipe plug valve (the valve you said).2, regular inspection of the skin tube leakage (3 months 1 can be this).3, the leather pipe and the leather pipe plug valve connected to the place has a ferrule, inspection found loose, must be tightened with a screwdriver, in case of leakage.4, the use of gas should pay attention to indoor ventilation, winter must open lampblack machine, in case of poisoning.Don't worry as long as you do the above.

Q:What valve is the VENT?

In order to reduce the leakage point, sometimes before the factory will be welded to death.DRAIN position must be in the lower position of the valve body, is generally able to reach the lowest point.

Q:The low pressure in our factory is below 1.6Mpa, medium pressure is 2.5-6.4MPa, high pressure is 10-80MPa.Where's qusetion:1.6-2.5Mpa??? Which section does it belong to?. I think many of them are defined on the Internet But I didn't say, where's 6.4-10Mpa?

Low high is just a general statement, such as the height, there is no clear distinction between what theNow the pressure piping fittings design is specific to the pressure value, not to say that the place to install a medium pressure valve.The pressure piping is generally classified according to the pressure, and the valve can be distinguished by this.Of course, you say 2 of the medium pressure valve is also OK, belong to the low-pressure valve, no one was investigatedBy pressure:1 、 low pressure pipeline engineering pressure less than 1.6MPa;2 、 medium pressure pipeline engineering pressure 1.6-6.4MPa;3 、 high pressure pipeline engineering pressure 6.4-10MPa;4 、 super high pressure pipeline engineering pressure 10-20MPa.

Q:What is a hot melt valve?

For the pillars of the temple are scattered on both sides,I first saw you when I was about to leave.The prey in the net is a star.Far away, where you are nowBecause I love you。For a very Chinese, this ha ha!

Q:What kind of industry does valve belong to?

Valves are machinery and industry equipment；Valve belongs to general mechanical equipment

Q:Valve connections - two how do different connections work?

The connection of two different connection forms is achieved by a transition conversion connector
