- Q: Replacement method of PPR hot melt ball valve
- 2, if the valve is directly welded on the pipeline, you need to stop the operation of pipeline, and cutting, the need to replace the valve flange or screw type ball valve, ball valve flange need two "steel plastic adapter" heat welding with the original pipe, the flange type ball valve can be installed; the screw type two single head, a head and pipe welding / bonding, joint head and ball valve with wire of threaded connection.
- Q: What's the difference between angle valve and ball valve?
- Ball valve, as its name suggests, is the shape of a ball valve, water from the hole in the middle of the ball out, usually the handle to control the opening and closing. But the ball valve can only be switched on and off, and can not adjust the flow. To put it plainly, you take it half open and half closed, and its flow is not about 50%, and fluctuates greatly. In addition, if the ball valve will be half closed, it will damage the ball valve, greatly shorten its life. Ball valve is mainly used for heating hot and cold water inlet pipe.
- 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: How does ball valve indicate?
- Valve type designation method is standard, the landlord himself to check the JB/T308 standard, Baidu library some, and is free to download:JB/T 308-2004 valve type method of preparation clear Edition
- Q: Is the integral type split ball valve structurally identical?
- Split type ball valve, the valve body by the main body and the cover body is composed of two parts, thread connection between the main body and the cover body is arranged at the connection of the sealing ring, an annular sealing ring and ball valve, valve rod, sealing gasket, valve stem nut, a handle, a fastening nut is arranged on the main body, there is another ring the sealing ring is arranged on the cover body, interface screw holes at both ends of the valve body are respectively processed in the main body and cover body. This structure of the ball valve, the ball cavity depth is relatively shallow, the ball cavity processing is more convenient.
- Q: Stainless steel ball valve Q41F-16P DN80 weight is
- The whole diameter is about 40kg heavyThere is a slight difference between the manufacturers
- Q: Flange ball valve Q41P3-150C2, DN50, RF, WCB/316 hardening, each letter number represents what?
- Q-- ball valve; 4-- flange connection floating structure; 1---; P--- sealing material: boroning steel; nominal pressure 150:--- 15MPa;C--- body material: carbon steel; DN50--- nominal diameter; RF--- flange sealing form (convex flange); WCB--- carbon steel castings; 316---- austenitic stainless steel
- Q: What is the principle of forced sealing ball valve? How to achieve mandatory sealing function? Is it suitable for high pressure conditions?
- With spring to achieve forced sealing, not applicable to high pressure
- Q: Advantages of track ball valves
- 1., the fluid resistance is small, and the coefficient of resistance is the same length as the pipe section. 2., simple structure, small size, light weight. 3., close and reliable, at present the ball valve sealing surface materials widely used plastic, good sealing, vacuum system has also been widely used. 4 easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control. 5., maintenance is convenient, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient. 6. in full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, it will not cause erosion of the valve sealing surface. 7., a wide range of applications, from small diameter to a few millimeters, large to several meters, from high vacuum, high pressure can be applied.
- Q: Ball valve use?
- Ball valves are widely used in petroleum refining, long-distance pipeline, chemical, paper making, pharmaceutical, water conservancy, electric power, municipal, steel and other industries, and play a decisive role in the national economy.
