Q:What is the diameter of the 2 inch ball valve?

2 inch ball valve, diameter is two inches.Turn left and turn right |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 to rotate the valve movement. 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.Turn left and turn right |The answer is recommended by He Xiaoqiang, a member of the science education category

Q:Here, the original water leakage, has not been closed, recently closed for other places, twisted two times, and now it is so,Ball valve leakage of this place, how do? Here, the original water leakage, has not been closed, recently closed for other places, twisted two times, and now it is the case, how can I ask?

Ball valve can be closed on both sides, change to the other side closed, try, and if the water is still leaking, the middle of the core screw is prohibited,

Q:What are the uses and characteristics of copper ball valves?

4, good sealing performance5, the direction of installation is not limited, the flow of media can be arbitrary

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's the diameter of the 4 point ball valve?

"4 point ball" in the "4 points" is based on the length of units per inch evolved;Divide 1 inches (25.4mm) 8, 4 points 4/8, or 1/2 inches, equal to 12.7mm.Therefore, "4 points ball valve" diameter is 12.7mm.

Q:The two valves are available for the flow of the electromagnetic valve switch, I contact more, found for water solenoid valve are caged water, to repair several times because of impurities or newly installed pipeline with raw materials flowing through the valve, close the valve body when not to rely on Yan, a seepage water tank to diffuse phenomenon!I am looking for a replacement, I think the electric valve should be a good choice, not used to a conclusion.Please use the electric ball valve to talk about friends, or for the two kinds of friends who have an understanding to talk aboutOr there is no better substituteThere seems to control the solenoid valve and electric valve is not the same, the solenoid valve is normally open and closed to control the electric valve is controlled by the trigger (like), if used to replace it, what is the controller?

Solenoid valve on the medium cleanliness requirements are very high, when the water is not clean, easy to leak. You use the solenoid valve is leaking, that's the case.If you have an air source, use pneumatic angle seat valvesIf only the power supply, the electric ball valve.Electromagnetic valve is electromagnetic rail, electric suction from the electromagnetic core, so that the valve openThe electric ball valve is driven by the motor to drive the valve open. If only switch, then do not need to install any controller, when buying, must explain is the switch ball valve.This answer was net friend adoption

Q:Is the water inlet valve good or the ball valve well?

Water valve at home as far as possible not to use the form of valve, gate valve for water, slag better, shut down with the next valve and ball valve. Just don't buy cheap goods, cheap ball valves use a period of time, gland leakage, spool corrosion must be replaced.

Q:PE pipe size diameter 3/8, diameter 1/4, material: low density polyethylene, pressure 170psi;Valve material: copper, and PE pipe connection interface with lock nut.Is this connection reliable? Will the pipe break due to excessive compression? Are there any requirements for the size of the joint and the size of the nut?

First, 170psi pressure is not great, not excessive extrusion and rupture of polyethylene, but there will be stress relaxation phenomenon, is a long time there will be some loose, suggest you nut and pipe with tight mechanical connection is good, the data has not been studied, can only give you a suggestion: 24-48 hours after the installation is complete then a proper tight.

Q:Which is more cost-effective electric ball valve?

All kinds of Lady valve manufacturers.The company has strong technical force, with adequate and sophisticated machining equipment as the premise, to provide a strong guarantee for the production of high-quality products,

Q:What's the advantage of using an electric ball valve?

Shanghai power code solenoid valve on the official website introduced the benefits of four point electric ball valve, 1. for two cutting, adjusting the occasion. 2., electric ball valve can be achieved on the petroleum, chemical, paper, metallurgy, sewage treatment, oil tanks and other transport pipeline cutting off the medium and circulation. 3., good sealing performance, large flow capacity, convenient handling and maintenance, small flow resistance, reliable sealing, and even cut off. 4. 、 electric valve is small, light weight, big thrust, powerful function, servo amplifier built-in, easy to operate, high reliability.
