The three major advantages of fluorine-lined valves explain why they are popular! The structure of fluorine-lined valves is different from the valves commonly seen in daily life. The opening and closing of these valves are mainly controlled by the valve stem, whereas in everyday valves, the operation does not rely on the valve stem. Its structure and manufacturing process have many advantages. If you're interested, let's explore its features together.
Fluorine-lined valve The three major advantages, there are reasons why it is popular!
Fluorine-lined valve Its structure is different from the valves commonly seen in our daily life. The opening and closing of this valve is mainly controlled by the valve stem, whereas in daily life, valve operation does not rely on the valve stem. Its structure and manufacturing process have many advantages. If you are interested, let's learn about its features together.
1. Strong corrosion resistance
Fluorine-lined valve The lining material used is a fluoroplastic lining layer. This material has strong corrosion resistance and can withstand highly corrosive chemical substances. It has strong chemical stability and high durability, basically unaffected by chemical materials. Therefore, if used properly and maintained regularly, its service life is relatively long.
2. High safety
The ball and valve stem of this valve are integrated, so even with large pressure changes, the internal pressure-bearing components are less affected, fully ensuring safety during use.
3. High convenience
The fluorine-lined valve has a full bore floating ball valve structure. This structure is more effective in pressure distribution, with tight connections between components and strong dredging capability, allowing for later system management and maintenance. Repairs are very convenient, with fewer troubles during the entire repair process, and do not require specialized professionals to operate.
Mechanical failures and root causes. Fluorine-lined valve After the pipeline network has been in operation for a period, various common failures may occur. Firstly, it is related to the number of parts that make up the gate valve. The fewer the parts, the more mechanical failures occur. Secondly, it is related to the design, manufacturing, installation, actual operation, and maintenance of the gate valve. Generally, common failures of non-driven gate valves can be roughly divided into four categories:
1. Damage and cracking of the oil circuit board.
Causes of damage and cracking of the oil circuit board: reduced rust resistance of gate valve materials; concrete cracks in the pipeline; large changes in working pressure or temperature difference in the pipeline network; water hammer; poor actual operation when the gate valve is closed. Immediately remove foreign object interference and replace with the same valve or gate valve.
2. Common failures of gear transmission.
Common failures of gear transmission mainly manifest as valve seat jamming, inconvenient operation, or inability to operate the gate valve.
Causes are as follows: gate valve rusts after being closed for a long time; simple installation, damage to the external thread of the valve seat or valve seat nut; gate valve stuck by dirt on the valve body; gate valve usually in half-closed state. Due to hydraulic or other impacts, displacement, loosening, and jamming between seat screws and seat nuts; packing pressure too tight, wheel stuck to seat; valve seat jammed by top or closing parts. During repair, lubricate the drive system position. Use a wrench and light tapping to clear jams and dead angles; shut off water for repair or replace the gate valve.
3. Poor gate valve opening and closing.
Poor gate valve operation mainly shows as inability to open or close the gate valve. The gate valve cannot work normally. Causes include: valve seat rust; gate valve stuck or rusted due to long closure; gate valve falling off; maintenance under left or right conditions. Lubricate the drive system position; repeatedly open and close the gate valve, use hydraulic power to loosen mud; disassemble and replace the gate valve.
4. Gate valve leakage.
Gate valve leakage mainly manifests as: leakage at the valve seat core; leakage at the nut; leakage at the flange gasket.
Common causes include: damage, corrosion, or peeling of the valve seat (valve stem), convex or concave dents peeling off; sealing brittleness and leakage; loose nut or flange foot bolts. Loosened flange foot bolts. Dimension increase. Remove and replace sealing materials; remove and replace new nuts, readjust and tighten foot bolts.
No matter what kind of common failure, as long as it is under normal maintenance. If not maintained in time, it will cause water resource waste and even paralysis of the entire system software. Therefore, gate valve maintenance personnel need to understand the common causes of gate valve failures, be skilled and accurate in adjusting and operating gate valves, promptly and decisively resolve various emergency common failures, and ensure the normal operation of the sewage treatment pipeline network.
After reading the above content, do you still remember Fluorine-lined valve the advantages? This type of valve has manual and automatic types. If you want to purchase, it is not only important to understand its advantages but also to know the specific classifications.
