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: What is the normal temperature on the valve?
- What's the valve?. Conventional valves are 425 degreesIf it's on the oil field. It's only 120 degreesAt normal temperatures are below 120 degrees. A lot of valve sealing surface can only reach 120 degrees
- Q: What kind of valve is it? How do you see the status of the switch?
- This is called gate valve. The core is opened and the core is screwed down. Turn left and right.
- Q: What are the other valves used for the control of dual-use items?
- That is to say, your valve needs to be used as dual-use items and technology import and export licenses. Shanghai import and export can find me. We have electronic keys for dual-use items
- Q: Symbols for all types of valves
- Look at the attachment I gave you. The legend of the valves is complete!
- 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
- Q: How big valves are used in the DN90 pipeline?
- If you use a 97 tube, the inner diameter of 89- phi 90., nominal pressure is low, then try to use DN80, DN80 valve diameter of 80, you can try butt welding
- Q: What should be checked before using the valve?
- The valve must be tested before installationI. examination of documentsThe valve must check the quality documents before installation, the valve manufacturer should be nameplate, nameplate and the body should be the name of the manufacturer, valve type, nominal pressure, nominal diameter and logo, must comply with the "universal valve logo" GB 12220.Two, appearance inspection
- Q: How does the valve open?
- Turn the valve counterclockwise, turn clockwise, or turn left, right and leftYou turn the valve to the left.
- Q: How to better maintain the valve?
- How to maintain the valve?Enter the same as other mechanical products, but also the need for maintenance. This work well, can extend the service life of the valve, the following will introduce the valve maintenanceStorage and maintenanceThe maintenance of the purpose is to keep the valve in the custody of the damage, or lower quality. In fact, improper storage is one of the important reasons for valve damageThe valve custody, should be arranged in good order, a small valve on the shelves, large valves can be neatly arranged in the warehouse on the ground, not arbitrary lumber pile, do not let the flange face contact with the ground. This is not only for beauty, mainly to protect the valve, not to touch badBecause the storage and handling properly, hand wheel broken, crooked stem touch the fixed nut hand wheel and stem loosening loss and so on, these should avoid unnecessary losses.We temporarily on the short-term use of the valve, should remove the asbestos packing, in order to avoid electrochemical corrosion damage to the valve stem.I just entered the library on the valve, to conduct inspections, such as during transport into the water or dirt to wipe clean, re storedThe import and export of valves to use wax paper or plastic sheet sealed to prevent dirt insideThe valves on the machined surface rust in the atmosphere should be coated with anti rust oil, protectI placed outside the valve, must be covered with linoleum or tarpaulins like rain, dust items. Keep the storage of the valve clean and dry
- Q: What are the general types of valves?
- There are generally 3 types of ball valve, globe valve, ceramic core valve
