Q:What is the force distance of a ball valve with a diameter of 150mm?
Reference: ball valve 1000N on the line, butterfly 250N canThis valve with the switch torque is related, each manufacturer according to the workmanship, process switching torque is not the same.You can refer to the recommended value of the actuator manufacturer
Q:Under what circumstances with the butterfly valve, under what circumstances with the ball valve?
Butterfly valve for occasions:Butterfly valve is suitable for flow regulation. Due to the pressure loss of the butterfly valve in the pipe is relatively large, is about three times the gate, so the choice of valve, the piping system should fully consider the influence of the pressure loss should also be considered robust when closing the butterfly plate to withstand the pressure medium pipeline. In addition, the operating temperature limit of resilient seat materials must be taken into account at elevated temperatures.Butterfly valve structure length and overall height is small, open and close speed is fast, and has good fluid control characteristics, butterfly valve structure principle is most suitable for making big mouth valve. When the butterfly valve is used as a control flow, the most important thing is to choose the size and type of butterfly valve so that it can work properly and effectively.Usually, in throttling, adjusting control and slurry medium, the structure length is short and the opening and closing speed is fast (1/4 rpm). Low pressure cut-off (small pressure), butterfly valve is recommended.Butterfly valves can be used in double adjustment, necking channels, low noise, cavitation and gasification, with little leakage to the atmosphere and corrosive media.
Q:What is the difference between ball valve and butterfly valve?
The butterfly valve consists of valve body, valve seat, valve plate, valve rod, all parts are a significant drain on the outside, one eye can see; and the ball valve is composed of a valve body, the valve core (a round ball), valve rod, valve position is in the valve body inside, the naked eye can see only a part, so the sealing performance of the ball valve than the butterfly valve; butterfly valve structure is relatively simple, generally with low pressure valve, high pressure valve can reach 64 kg. The ball valve structure is relatively complex, more resistant to high pressure, the ball valve up to 100 kg.Butterfly valves are divided into soft seal and seal, soft seal butterfly valve is generally perpendicular to the center of the plate, is the valve plate, valve seat, valve stem is the center position of the highest temperature soft sealing butterfly valve is 150 degrees below the pressure of 16 kg, hard seal butterfly valve can be divided into single eccentric, double eccentric, three eccentric, we generally use more than three eccentric, because the three eccentric according to its structure, better sealing performance, hard seal butterfly valve pressure is 64 kg; the valve can also be divided into soft seal and seal, soft seal valve maximum temperature is below 280 degrees, the pressure is on 64 kg, hard seal ball valve temperature can reach 425 degrees below the pressure below 100 kilograms. Shanghai Sino US valve for your answer, for reference.
Q:What does copper ball valve mean by "1/2"?
This indicates that the caliber of copper ball valve is DN15
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:What does the sealing surface of the ball valve stand for HF?
The sealing surface HF of the ball valve represents the surface hardening treatment.Ball valve (ball valve), standard GB/T21465-2008 "valve terminology" is defined as: "open and close parts (spheres) driven by the stem, and around the axis of the ball valve for rotation of the valve.". Can also be used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fibers, small solid particles and other media. Switch and multi way valve in the pipeline not only can flow, and flow diversion, flexible control of the medium, but also to turn off any channel to the other two channels. This kind of valve should be installed horizontally in the pipeline. In accordance with the way to drive the ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball valve.The ball (ball valve) published in 1950s, with the rapid development of science and technology, the continuous improvement of production process and product structure, in a short span of 40 years, has become one of the main valve. In western developed countries, the use of ball valves is increasing year by year.
Q:What is the ball valve core?
The ball (ball valve as the cut-off valve in the marine and marine field), standard GB/T21465-2008 "valve terminology" is defined as: opening and closing parts (ball) driven by the stem, and around the valve axis for rotation of the valve. Can also be used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fibers, small solid particles and other media. Switch and multi way valve in the pipeline not only can flow, and flow diversion, flexible control of the medium, but also to turn off any channel to the other two channels. This kind of valve should be installed horizontally in the pipeline. In accordance with the way to drive the ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball valve.
Q:Flange ball valve Q41P3-150C2, DN50, RF, WCB/316 hardening, each letter number represents what?
Q-- ball valve; 4-- flange connection floating structure; 1---; P--- sealing material: boroning steel; nominal pressure 150:--- 15MPa;C--- body material: carbon steel; DN50--- nominal diameter; RF--- flange sealing form (convex flange); WCB--- carbon steel castings; 316---- austenitic stainless steel
Q:What does "q41f46-16c-dn40" mean?
DN40 refers to the nominal diameter, 16C represents 16 kg of pressure, carbon steel material F46 stands for fluorine
Q:What do you mean by 266 in the 266 brass ball valve?
This is the Ningbo aimeike Copper Valve Co Ltd model, 266 is only a brass ball valve series, specifically to check samples.
