Q:What's the difference between angle valve and ball valve?

Angle valve is called "angle valve", because its inlet and outlet are 90 degrees angle perpendicular to each other, rather than straight into the ball valve straight out. Angle valve to cut off media, to facilitate the maintenance of terminal equipment, generally used for washbasin, kitchen sink, toilet water tank, water heater, cold and hot water inlet pipe. When an accident occurs in the water pipe or breaks and leaks after many years, then the angle valve is closed, which does not affect the normal water consumption at home and avoids economic losses.The ball valve has the same rotation 90 degrees of movement, different is the cock body is the sphere, has the circular through hole or the passage through its axis. Ball valve in the pipeline is mainly used to do cutting, distribution and change the direction of media flow, it only need to rotate 90 degrees of operation and a small rotating torque can be closed tight. Ball valve is the most suitable switch, shut-off valve, but the recent development of the ball valve has been designed so that it has throttling and control flow, such as V ball valve.

Q:Is the integral type split ball valve structurally identical?

Split type ball valve, the valve body by the main body and the cover body is composed of two parts, thread connection between the main body and the cover body is arranged at the connection of the sealing ring, an annular sealing ring and ball valve, valve rod, sealing gasket, valve stem nut, a handle, a fastening nut is arranged on the main body, there is another ring the sealing ring is arranged on the cover body, interface screw holes at both ends of the valve body are respectively processed in the main body and cover body. This structure of the ball valve, the ball cavity depth is relatively shallow, the ball cavity processing is more convenient.

Q:And the cut-off valve is not the general name of gate valve and butterfly valve?What are the signs of differentiation?How about the use?

When the valve is opened, the opening height of the valve is 25% to 30% of the nominal diameter, the flow has reached the maximum, which means that the valve has reached full open position, so the opening position of the stop valve should be determined by the stroke of the discThe cut-off valve has the following advantages:The utility model has the advantages of simple structure and convenient manufacture and maintenanceSmall travel time, short opening and closing timeGood sealing, friction between the sealing surface of small, long lifeThe disadvantages of the cut-off valve are as follows:The resistance of fluid is large, and the force required for opening and closing is largerNot suitable for medium with particle, viscosity and easy cokingPoor regulation performanceType valve stem according to the position of divided threaded screw type, internal thread. Divided by the flow of media, there are straight through, DC type and angle type. Divided by the form of valve seal, a packing seal bellows seal valves and valve.The installation and maintenance of the cut-off valve shall pay attention to the following matters:The stop valve operated by the handwheel and handle can be installed in any position of the pipeHand wheel, handle and steering mechanism are not allowed to be used for liftingThe flow direction of the medium shall be in accordance with the arrow shown in the valve body

Q:Switch valve type, switch valve, ball valve or butterfly valve is good

Ball valve and butterfly valveBall valve is 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.Butterfly valve, also known as shutter valve, can be used to control the air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. On the pipeline, mainly from cutting and throttling.

Q:The working principle of the track type ball valve

Baidu under the Wuxi East valve, have their contact information, you can consult them

Q:Home tap water valve (ball valve) half open or well open, open half is not love rust live?

Open it all. If the water is half opened, the water on the upper deck will not go up or down due to low water pressure. As the owner said, half of it will rust. So...

Q:The toilet water pipe valve is broken, with a new twist, how are the screw does not move, then they told me to go on to the pipe on the water and then tighten, did as he said, really screwed, but do not know why, please tell the master what is the principle, if it is water without water when the screw does not move, but when the water can twist. What a kink!Is the water valve normal, a pull rod, pulling it back flush, do not rush the kind, the middle is a hollow ball

I think it should be the water holding gas, connecting device principle, at the bottom of the hand, barometric pressure, and the best you can last map, I'll see

Q:Ball valve? I require the valve to control both sides of the liquid, one side with liquid flow, and the other side closed!

This is a manual ball valve three simple when meet your requirements is L ball valve

Q:3/43/8 above the ball valve is not usually said of the big ball valve?

That is the calculation of the imperial, generally divided into two types, 1 inch (in.) 2, metric (mm) swap inch metric 1/4 (2) =6 3/8 (3) =10 1/2 (4) =12 5/8 (5) =16 3/4 (6) =18 7/8 (7) =22 1 1/8 (1 inch 1) =28,

Q:Replacement method of PPR hot melt ball valve

The above problems belong to the wire type, and the name is: double live catch valve, directly loosen the lock nut, replace the valve can be.When the valve is purchased, the merchant sells a full valve. When the change is made, both ends of the live joint lock nut are removed and the valve is directly connected with the original lock nut on the pipe.
