Q:What's English for ball valves?: Mechanical introductionThe main characteristics of the electric ball valve of the valve itself is compact, easy operation and maintenance for water, solvents, acids, and natural gas general working media, but also applies to poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be integrated, or can be combination. Ball valve in the pipeline is mainly used to do cutting, distribution and change the direction of flow medium. Ball valve is a new type of valve widely adopted in recent years. The resistance of fluid is small, and its resistance coefficient is equal to that of pipe of same length.The ball valve is simple in structure, small in size and light in weight. Tight and reliable, at present, the ball valve sealing surface materials widely used in plastic, good sealing, vacuum systems have been widely used. Convenient operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control. Easy maintenance, ball valve structure is simple, the sealing ring is generally movable, disassembly and replacement are more convenient. In full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, will not cause the valve sealing surface erosion. Wide range of applications, from a few millimeters to a few millimeters, large to a few meters, from high vacuum, high pressure can be applied.It is generally believed that the ball valve is suitable for direct opening and closing, but the development of the ball valve has been designed to make it throttling and controlling the flow. The main features of the valve itself is compact, easy operation and maintenance for water, solvents, acids, and natural gas general working media, but also applies to poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be integrated, or can be combination.

Q:Ball valve? I require the valve to control both sides of the liquid, one side with liquid flow, and the other side closed!: I don't know. Solid geometry will happen. God knows me. Suddenly, barriers and French goods

Q:What are the advantages of an air operated ball valve in comparison with other types of valves?: Compared with other kinds of valves, pneumatic ball valve has angular travel, output torque, quick, stable and reliable opening, wide application and the following advantages.Antistatic function: a spring is arranged between the ball body, the valve stem and the valve body, so that the static electricity generated by the switching process can be exported.Long service life: because PTFE and other materials have good self lubrication, and friction loss of the ball is small, so pneumatic ball valve.Fluid resistance is small: pneumatic ball valve is the classification of all types of liquid resistance is the smallest, even if the diameter of pneumatic ball valve, its fluid resistance is quite small.Stem seal is reliable: it has two sealing surface, and the ball valve sealing surface materials widely used, all kinds of plastic, good sealing, can achieve full seal. It is also widely used in vacuum system. Because the stem only for imitation rotation transported without movement, stem packing seal is not easy to damage, and sealing ability increased with the increase of the pressure medium.Valve seat sealing performance: the use of PTFE and other elastic materials made of sealing ring, the structure is easy to seal, and pneumatic ball valve sealing capacity as the medium pressure increases.

Q:Ceramic ball valve, regulating valve standard?: You can refer to the specific national standards

Q:Stainless steel ball valve, Q11F-10P, 16P, 11F, what does that mean?: The first 1 that connect the second ball, 1 straight through valve, F PTFE sealing.

Q:Calculation formula of ball valve flow: The sectional area of diameter of DN15, DN25 and DN50 is respectively:DN15:15*3.14/4=176.625 mm, 0.0177 square decimeter.DN25:25*3.14/4=490.625 mm, 0.0491 square decimeter.DN50:50*3.14/4=1962.5 mm, 0.1963 square decimeter.A pipe flow rate of V=4 M / s V=40 decimeter / s, and the 1 liter =1 cubic meter, the pipe flow respectively (cross-sectional area multiplied by the velocity):DN15 pipe: flow Q=0.0177*40=0.708 L / sec,It's 2.55 cubic meters per hour.DN25 pipe: flow Q=0.0491*40=1.964 L / sec,It's 7.07 cubic meters per hour.DN50 pipe: flow Q=0.1963*40=7.852 L / sec,It's 28.27 cubic meters per hour.Note: a flow rate must be given to calculate the flow rate, which is calculated in accordance with 4 meters per second. Reference: http://zhidao.baidu /question/77687541.html answer: good night dream | six | 2010-5-24 22:46It's 600 cubic meters / hour!Flow Q=600 m3 / h = 0.167m^3/sThe flow rate is V=4Q/ (3.1416D^2) = 4*0.167/ (3.1416*0.090^2) = 26.25 m/s, and the flow velocity is very large!It could be 600 cubic meters per day:Flow rate Q=600 m3 / day = 0.00694 m^3/sFlow rate V=4Q/ (3.1416D^2) = 4*0.00694/ (3.1416*0.090^2) = 1.09 m/s flow rate is normal.

Q:Difference between fireproof and antistatic ball valve and ordinary ball valve: Therefore, the general manufacturers will be made fire-resistant, anti-static.I do the valve above all hand typing, and if the answer is satisfactory, please adopt in good time Oh. There are questions to ask!!!

Q:The difference between gate valve, ball valve and butterfly valve: Butterfly valve plate and the ball valve is rotated around its own axis for movement; valve plate valve for the lifting movement along the axis; butterfly valve and gate valve can adjust the flow through the opening; the ball is not easy to do this.1. The sealing surface of the ball valve is spherical2. The sealing surface of butterfly valve is circular cylindrical surface3, the sealing surface of the gate valve is flat.

Q:Pneumatic ball valve q641f-16p what do you mean?: Q is a ball of the code, 6 representative driving mode is pneumatic, 4 flanged ball valve structure is straight through channel 1 on behalf of the floating ball, f sealing surface is the fluorine plastics, 16 represents the pressure of 16 kg, P represents the body material is stainless steel, Shandong Huadian valve.

Q:What does "ball valve" Q41F-10P mean?: Q valve (Qiu represents the first letter of the alphabet), 4 representative flange, second representative is 1 ball valve floating ball (ball valve floating ball and fixed ball, 7 ball, F fixed on behalf of) on behalf of PTFE- PTFE seal (PTFE PTFE), representing 10 of the nominal pressure valve is 10 kg (1.0Mpa), P represents the valve body material is 304 stainless steel.Soft sealing stainless steel flanged ball valve
