1.Structure of  Ball Valve Description

Threaded ball valve is closed is a ball, ball around the center line of the body as a rotation to achieve a kind of open and close the valve.
Ball valve in the line is mainly used for cutting, distribution, and change the flow direction of medium. Two type ball valve, three type ball valve, is widely used in recent years a new type of valve, the valve average installation. And ball valve is a kind of ball valves, threaded pipe connection is screwed connection, and flanged ball valves, welded ball valve, etc.

2. Main Features of the Ball Valve

• Small flow resistance;

•  Simple structure

• Small volume, light weigh

• Small volume, light weigh

•  Easy to operate, open and close quickly, facilitate remote contro

• Easy maintenance, sealing ring, which generally remove easy to change

• Full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through does not cause the valve sealing surface erosion.

1. What's are the characteristics of ball valve?

The distinct feature of a ball valve is the sealing surfaces between the gate and seats are planar, so ball valves are often used when a straight-line flow of fluid and minimum restriction is desired. The ball valve faces can form a wedge shape or they can be parallel. 

2. What is the work principle of ball valve

 The ball valve faces can form a wedge shape or they can be parallel. Ball valves are primarily used to permit or prevent the flow of liquids, but typical ball valves shouldn't be used for regulating flow, unless they are specifically designed for that purpose. Because of their ability to cut through liquids, ball valves are often used in the petroleum industry. 

3.  What is the structure?

Bonnets provide leakproof closure for the valve body. Ball valves may have a screw-in, union, or bolted bonnet. Screw-in bonnet is the simplest, offering a durable, pressure-tight seal. Union bonnet is suitable for applications requiring frequent inspection and cleaning. It also gives the body added strength. Bolted bonnet is used for larger valves and higher pressure applications.

Q:Valve should be strictly marked according to the direction of instructions and media flow direction to determine the installation direction,
Strength of the corresponding meaning is: the valve used to connect the original way of normal connection, such as silk mouth with the same specifications of the silk mouth connection. You can't connect the wires with different sizes.The pipe clamp is fixed in the counterpart application, from the interface at 200mm was measured with a ruler, when the nominal diameter is less than 100mm, the tolerance of sigma <1mm, when the nominal diameter is greater than 100mm, tolerance for a <2mm, but the length of tolerance is less than 10mm, no strong counterpart or eccentric pad counterpart.
Q:Where is the Shanghai valve? What brand is good?
Shanghai Dapu Valve Co. Ltd.Amico jiekelong shield, doing a good job
Q:What does the whole copper valve mean?
Industrial oxygen pipes on the valve are all copper valve, hand wheel is not. The market had had 4 6 1 inch screw valve also has a lot of full copper. The tap also has all brass. The valve body and the inside are all copper.
Q:What does the torque of the valve mean?
The torque of the valve is the opening moment of the valve (valve torque): Newton meter.The opening moment, also known as the operating torque, is the most important parameter for selecting the valve actuating device. Opening torque is also a measure of the quality of the valve product is another important indicator, people in the evaluation of valve quality, commonly used valve opening light, flexible to describe it. In some advanced industrial countries in the pipeline valve standards, as one of the assessment indicators, and provides manual valve opening torque is not more than 360N • M. More than this moment, it is necessary to consider the use of suitable driving devices (such as electric, pneumatic, hydraulic devices). Some manufacturers will open the torque printed in the product samples, user-friendly.
Q:What's the advantage of using three way valves?
The principle of three way valve:The most obvious three valves and other valves is the difference in appearance, three way valve has three channels, mainly used to change the medium to flow through valve three, which in addition to import A, B, C and reversing port of export, common valve is not capable of changing the flow direction of medium function. The flow direction of the medium can be determined according to requirements.
Q:Chinese valve and a valve which is better?
Look what valve you use, ah, these two can be ah!
Q:G what's the meaning of the valve?
G is the diaphragm valve, valve type code, there are other types of valve code.A D is a safety valve, butterfly valve, check valve (H valve), J is the cut-off valve, throttle valve is L, P is Q is the drain valve, ball valve, S trap, U X is a plunger valve, plug valve, Y valve, Z valve.
Q:Is there any problem with connecting the geothermal valves with other geothermal pipes?
Yes, as long as it's all PPR's.Material is the same, the fuse will not cause shrinkage when you can use
Q:How to check if the gas valve is open?
There is a switch on the valve indicating that you can follow the above operation
Q:What does the valve stroke mean?
The distance from one position to another. Usually in the first position of the cut position, the second position is put through the position. Unless the valve has 3 positions.
