Q:One stainless steel ball, two pieces, three pieces of difference, use
A piece of ball valve, that is, the principle of Canton style ball valve is to rely on rotary valve to make the valve open or blocked. Valve switch light, small size, can be made large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, the media can not easily be eroded, widely used in various industries.
Q:Domestic water pipe ball valve or cut-off valve?
Ball valve: rotate 90 degrees to switch, but the performance of the valve relative to the cut-off valve.
Q:Is the drain valve the same as the ball valve?
Not the same, the drain valve generally refers to the pressure relief valve, when the pipe pressure exceeds the pressure set by the valve, it began to relieve pressure, when the pipe is less than the pressure set by the valve, automatically shut down. Ball valve can only achieve the switch function. Of course, if you take the ball valve as the drain valve, you can also only manually manual operation, and the pressure relief valve is automatic.
Q:Advantages and disadvantages of ball valves and scope of application?
Ball valve and valve are generally used for fluid switching and flow, usually can not be used for flow regulation, and in addition to the valve can be used for fluid switching and cut-off, can also be used for flow regulation. If you need to adjust the flow rate, it is better to use the medium valve. The valve operation is very convenient, rapid and labor-saving, generally as long as the valve handle can turn 90 degrees, and the ball can be used not too pure (solid particles) fluid because of its spherical valve core of the fluid in the opening and closing of the shear movement. The gate seal between easy to cause erosion and abrasions, maintenance more difficult, larger size, open need a certain space, opening and closing time is long, complex structure.As you say, the ball valve is generally used for small caliber, because small caliber production is simple, relatively inexpensive, caliber increased production accuracy requirements, production costs increased, so the price will be high. Generally small diameter threaded connections, from the G1/4~G2 have.
Q:Stainless steel ball valve Q11F-10P 16P each letter meaning?
Q ball valve, the first 1 representatives of second representatives of 1 screw connection, 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 (1Mpa), P represents the ball body material is 304 stainless steel.Shanghai blue forest control valve Co., Ltd.
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.
Q:What is an eccentric hemispherical valve? How do you understand?
The eccentric hemisphere valve and the flange gate valve belong to the same type of valve. The difference is that the closing piece is a sphere, and the ball rotates around the center of the valve body to open and close a valve.
Q:Would you please tell me why the spring is placed in the valve seat? What's the function?
The spring can also reduce the impact of the material on the valve.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.
Q:About the characters on the ball valve (what do s and O mean?)
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:What does W represent in copper ball valve Q11W-16T?
Valve sealing materials are all valves of the body material, sealing surface material code with "W" said
