- Q: What is the difference between floating and fixed ball valves?
- Floating ball valve ball is floating in the medium under pressure, the ball can have a certain displacement along the center axis and pressed in the export side of the seat ring, to ensure that the export side seal and the inlet end cannot seal, the floating ball valve is a single force seal form.
- Q: The working principle of the track type ball valve
- With its unique structure, the spool rotation separation open, new technology design of mechanical seal pressure, is the most prominent advantages of the sealing surface does not produce friction, long service life, low operation torque, even if the medium water content of solid particles, sediment, short fiber and other impurities, high concentration fluid flushing sealing condition of body harsh, can maintain good sealing, to ensure the engineering equipment maintenance period in the safe and reliable operation.
- Q: What are the uses and characteristics of copper ball valves?
- Copper ball valve features:1, suitable for regular operation, quick and easy to open and close.2, fluid resistance is small.3, simple structure, relatively small size, light weight, easy maintenance.
- Q: The difference between ball valve Q341F and Q347F
- Ball valves Q341F and Q347F are straight through flow, worm drive, flange connection, soft sealing form. Different from Q341F, it is a floating ball structure, and Q347F is a fixed ball structure.Model meaning: Q34 worm gear flange ball valve, 1: floating ball valve;
- Q: O ball as general regulation of opening extent
- According to the actual demand, turn 90 degrees from the closed state to the maximum opening.
- Q: Home PPR pipe ball valve, which is good?
- Zhejiang harmonious tube industry, the quality is very good, the price is also affordable, I installed, I do not know how many. Ball valve broke, it must be cut, from the connection, the valve is broken, and another spool can be used
- Q: Would you please tell me why the spring is placed in the valve seat? What's the function?
- The spring can also reduce the impact of the material on the valve.Ball valve (ball valve), standard GB/T21465-2008 "valve terminology" is defined as: "open and close parts (spheres) driven by the stem, and around the axis of the ball valve for rotation of the valve.". Can also be 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. Switch and multi way valve in the pipeline not only can flow, and flow diversion, flexible control of the medium, but also to turn off any channel to the other two channels. This kind of valve should be installed horizontally in the pipeline. In accordance with the way to drive the ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball valve.
- Q: What's the difference between a medium-sized ball valve and a heavy ball valve?
- It's almost certain that you made an inquiry at the small valve manufacturer in Wenzhou.In fact, the main wall thickness is differentThe so-called heavy, is in accordance with the GB/T12237 Petrochemical ball valve wall thickness to designThe so-called medium-sized, is in accordance with the GB/T12224 steel ball valve wall thickness to design, two wall thickness of some difference, plus a little steal material, sphere do hands and feet, the price can be much lower.There is a light, that is the material does not meet the standards, basically sold to plumbing builders.
- Q: What are the CF8 and CF3M marks on the stainless steel ball valves?
- CF8 stands for 304 material, and CF3M stands for 316L.Stainless steel ball valves only need to rotate 90 degrees of operation and small rotating torque can be closed tight. Full equality of the valve cavity for the media to provide a small resistance, through the flow channel. The main features of the valve itself is compact, easy operation and maintenance, stainless steel ball valve can be used to control air, water, steam, all kinds of corrosive media, mud, oil, metals and radioactive liquid media and other types of fluid flow. Ball valve body can be integrated, or can be combination. This kind of valve should be installed horizontally in the pipeline. Stainless steel ball valve classification: stainless steel pneumatic ball valve, stainless steel electric ball valve, stainless steel manual ball valve. Stainless steel ball valve is divided into 304316321 stainless steel ball valve.The working principle of the ball valve is to rotate the spool to make the valve unblocked or blocked. Valve switch light, small size, can be made large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, the media can not easily be eroded, widely used in various industries.
- Q: What's a twin hot melt ball valve?
- The ball valve is defined with the ppR/PE hot melt plastic pipe connected with the ball valve hot melt connection, ordinary ball valves generally use the threaded connection or flange connection. Double hot melt ball valve is both ends of the hot melt way to connect the ball valve
