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:How to check the quality of the valve?
First of all, to check the appearance of the valve is smooth and smooth. Cast valves without sand holes and obvious flaws. Forged valves check nominal pressure or pound level. Second, check the material of the valve, that is, the material composition, this is very important, the material does not meet the standard on the device will be a big problem. Finally, check that the switch is sensitive and the signs are clear. Test pressure is the last step.
Q:How do you see the valve number?

Table 10 the sealing surface of the valve seat sealing surface or liner material code or liner material code sealing surface or lining material code or code of lining material tin based bearing alloy seal (Babbitt) B Monel M alloy T enamel C nylon plastic rubber X N steel boriding nitriding steel D P hard alloy Y fluorine plastic lining F lead Q ceramic G austenitic stainless steel R Cr13 stainless steel H S note: the plastic body directly processed seat sealing surface material code with "W". When the sealing surface of the sealing material is not the same, the material name is indicated by the material with low hardness. The value of the nominal pressure of 10 times, according to the number of MPa (1MPa=106Pa). The valve body material code represented by the letter, in accordance with the provisions of table 11. Table 11 the valve body material body material material code code code C chromium nickel molybdenum stainless steel R Cr13 stainless steel H S plastic steel chromium molybdenum copper and copper alloy I T malleable cast iron titanium and titanium alloys K A L Aluminum Alloy CrMoV V Cr Ni stainless steel P Z gray cast iron ductile iron Q. In the original standard of nominal pressure equal to or less than 1.6MPa gray cast iron and the nominal pressure is greater than or equal to 2.5MPa carbon steel valve omitted the code.
Q:Where is the valve used?
Water treatment, chemical, petroleum, biological pharmacy and so on are more used
Q:How are the types of valves classified?
Pneumatic and hydraulic valvesPneumatic valve and hydraulic pressure based on a certain air, water or oil as the power source, using the cylinder (or cylinder) and the movement of the piston to drive the valve, the general pneumatic air pressure is less than 0.8MPa, the hydraulic or hydraulic pressure is 2.5MPa~25MPa. Such as used to drive diaphragm valves; rotary gas and liquid drives are used to drive ball valves, butterfly valves, or plug valves. The driving force of the hydraulic device is large, and it is suitable for driving large diameter valves. If used for driving plug valves, ball valves and butterfly valves, the reciprocating motion of the piston must be turned into a rotary motion.
Q:Which industries need valves?
Valve application industryValve users in a wide range of industries, can be divided into petroleum, petrochemical, chemical, metallurgy, electricity, water conservancy, urban construction, machinery, coal, food and other. Among them, the machinery and chemical industry users are most concerned about the valve market, and their requirements for the valve is also higher. The largest users of valves are the petrochemical industry, the power sector, the metallurgical sector, the chemical industry and the urban construction sector.Valve application typeIn the application of the types of valves, machinery, metallurgy, petrochemical, chemical, urban construction and other industries, the application of the valve classification of the most. Especially in the machinery industry, all kinds of valves are basically applied. In addition to the mechanical industry, the safety valve is mainly used in chemical industry; butterfly valve is mainly used in petrochemical and metallurgy; diaphragm valve is mainly used in metallurgy, electric power and chemical industry; check valve is mainly used in metallurgy, chemical and petrochemical; valve mainly used in petroleum and chemical industry; the cut-off valve is mainly used in metallurgy, petrochemical, chemical and power sewage; valve is mainly used in petrochemical and chemical industry; the ball valve is mainly used in petroleum, chemical and metallurgy; valve is mainly used in chemical industry, electricity and construction; the valve is mainly used in chemical, metallurgical, power and food; used in petrochemical and metallurgy main plunger valve; plug valves are mainly used in chemical and metallurgical valve; mainly used in petrochemical, chemical and metallurgy; steam traps are mainly used in chemical and petrochemical.
Q:What's the name of the valve?
This is not a valve, it is a pipe bender.
Q:Yongde jiekelong valves and valves of the good faith
If I choose, I choose Amico...After all, Amico did 20 years of copper valves...Moreover, the valve of this brand, Amico more people know...Jake, Amico has been imitated, even the same type..Of course more than jiekelong imitate slightly, there are other more or less imitation point valve...But I wonder if you use a big valve or a small valve?,If it's a small valve, use Amico..Big valve, these two are expensive outrageous...You can discuss it when you have time...
Q:What does LBC mean in a valve?
LB and 800 are together. 800LB means 800 pounds of stress, and P should be PRESSURE.Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow.
Q:What is the difference between a stop valve (a power station valve) and other valves?
High pressure, special material, complex structure, seldom manual operation.
Q:Where is the filling portion of the valve?
The valve stem and the body of the valve at the junction of the pressure cap, the pressure cap is filled inside.
