Q:What are the uses and differences of gate valves, butterfly valves, ball valves and other valves?: Valve and ball valve is generally used in the main pipe, long-term use, butterfly valve is often used frequently,

Q:Which valves are installed in a directional manner?: There are balance valve, safety valve, pressure relief valve

Q:The total valve of my natural gas was closed by the attitude I tried. Now I can't open it. I need to use gas. Who knows how to drive it? What skills do I have? I'm talking about the main valve.: General domestic weather is more ball valve, counterclockwise turn 90 degrees can.

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:How about leaking water pipe valve?: What specific circumstances, I teach you repair what valve, how big, which seal leaks

Q:What do letters represent in the QF-2 and PX-32 valve models?: You check it on the national standard! One is accurate!

Q:Remove the handle and lever the stem rotation with a wrench,: 1, carbon steel (WCA, WCB, WCC) applies to working temperature between -29 ~ 425 degrees between the middle and high pressure valve. Used for superheated steam. High temperature and low temperature oil, liquefied gas, compressed air, water, natural gas and other media.2 、 low temperature carbon steel (LCB) is suitable for working temperature between -46 ~ 345 Degrees of low temperature valve.3, alloy steel WC6, WC9 is suitable for the working temperature -29 to 595 degrees between the non corrosive medium high temperature and high pressure C5, C12, C12A for working temperature -29 to 650 degrees between the corrosive medium high temperature and high pressure valve.4 austenitic stainless steel for working temperature between -196 ~ 600 degrees corrosion of any medium valve.5,

Q:How do you calculate the valve wall thickness, pressure, and other valve design calculations in a spreadsheet?: Which standard does the wall thickness refer to? ASME B16.34?Design and calculation depends on what standard you chooseOr have you found the standard yourself and read it yourself?You choose what standards, design parameters reference, interpolation or fitting, how to fit, are their own sayI wrote a excel series of valve calculations, it does not take long to writeFor long-term useIn order to improve efficiencyOr write your own database program is better

Q:How to open the gas valve with drawings: First of all, you have to determine the direction of the valve opening, usually homeopathy, it is off, the reverse is open. First: to determine the opening of the valve, are generally ball valve, screw 90 degrees on it. Second. At the top of your house, there is a button that can be pulled out.

Q:How big valves are used in a DN159 pipe?: Nominal diameter DN150 corresponds to the outer diameter of De159To say DN159 is wrong, because DN is the nominal diameter (diameter in the middle of the tube wall)De159 refers to the outside diameter (outside the diameter of the wall)DN39 should be DN32. Nominal diameter 32, outer diameter 39.
