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.

5.FAQ
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: Is the valve clockwise?
- The valve that can rotate is the principle of screw and nut. We can see that the switch is also buckled, so it is counterclockwise, the net is rotated out, clockwise downward, so it is off.
- Q: I would like to ask how the valve entry, for a new pair, really difficult, what cutaway view, there are other, just contact the valve less than a week, and sometimes it is really difficult to understand. Forget the experienced teacher can be generous with your criticism to later, indebted forever, learn the valve Comrades some help.In a company CAD to relatives as soon as possible to a company, and then slowly improve, I do not know what is the request of the novice, and how to start as soon as possible, I am learning routine is: give me a set of valve design drawings, and then I paint it on, do not understand the structure and workshop look. I wonder if you have any good learning methods that can be referred to and supplemented by younger brother
- Valve range can be very wide, each company to do valve products are not the same;According to the company's production capacity and technology,Valve parameters to:1, valve spool material,2, connection mode (thread, welding, flange, clamp, socket welding, fast loading, etc.),3 caliber,4, medium (water, steam, oil, gas, liquid, etc.),5, temperature (medium temperature, environmental temperature),6, pressure (MPa, LB, K, etc.),7, configuration (executor and its accessories);A lot of valve requirements and this almost. Can also be selected according to the ideal valve function of customers.Switching type:Ball valve, butterfly valve, globe valve, gate valve, needle valve, etc.Regulatory type:Pneumatic valve, electric valve (adjustable type can be divided into: regulating temperature, regulating pressure, regulating flow), and so on
- Q: What does the valve "4" mean?
- An inch of eight points, home tap, valve is generally 4 points
- Q: What does "1/2" mean on the valve?
- 1/2 is 4 points (20), 3/4 is 6 points (25), and 1 is 1 inches (32)
- Q: What courses in the University involve valves?
- Fluid mechanics, "material mechanics", "mechanical design" and other courses on the design of the valve are helpful.
- Q: How do you calculate the valve wall thickness, pressure, and other valve design calculations in a spreadsheet?
- The valve wall thickness is the standard valve check directly in the relevant standard, for insert grade valves need to use interpolation method to calculate the valve wall thickness, actually don't need what difficult to complete in EXCEL software.
- Q: I used to do pumps, and now feel the future of the valve better, looking for a valve to do proxy, but my own economic strength is not good, I do not know if there is no possible to do?
- As the saying goes, the valve does not break up. The type of valve is too much, I do not know what you want to proxy valveIf you want to take advantage of the price, please go to Tianjin, or go to the township of Henan valve to see the followingIf you want to take advantage of quality, please go to Henan's Gaoshan Valve Co., Ltd., Yu Ming Valve Co., Ltd., Zhengzhou high and low pressure valve Co., Ltd... I am the valve distributor in Shenyang
- Q: The customer sent an inquiry sheet, in which check valve DE50, balance valve DE25, stop valve DE75, and I want to know what de stands for, because the price of plastic and cast iron is different. What does de usually mean in the industry?
- Back valve, DE50 balance valve, DE25 stop valve, DE75, what do you mean by "de"?Diameter DEThe diameter of a general plastic tube is indicated by DE in EngineeringNominal diameter is the size of all piping accessories in the piping system. The nominal diameter is a convenient round integer for reference and is not strictly related to the processing size. The nominal diameter follows the letter "DN" followed by a number sign.
- 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: What does the "Z45T-16" valve mean?
- Z - gate valve4 - flange connection5 - Dark pole, stem non lifting (gate valve structure)T - copper alloy, valve sealing face code16 - pressure code, 1.6MPaMaterial code for grey cast iron valves of nominal pressure less than or equal to PN16 shall be omitted in model preparation.May refer to JB/T 308 valve model compilation method
