Taike valve forged steel valves mostly use flange connection, which can be divided into the following types according to the shape of the connection surface: 1. Lubrication type: for forged steel valves with low pressure. Processing is more convenient 2. Concave-convex type: higher operating pressure, medium-hard gaskets can be used 3. Tongue and groove type: gaskets with greater plastic deformation can be used, which are widely used in corrosive media and have better sealing effects. 4. Trapezoidal groove type: Use an oval metal ring as a gasket, which is used for valves with operating pressure ≥64 kg/cm², or high temperature valves. 5. Lens type: The washer is in the shape of a lens and is made of metal. Used for high-pressure valves with operating pressure ≥100 kg/cm², or high-temperature valves. 6. O-ring type: This is a relatively new flange connection method. It is developed with the appearance of various rubber O-rings. It is a small connection method for sealing.
Pay attention to the details of the maintenance of forged steel valves of Taike Valves: 1. The storage environment of forged steel valves should be paid attention to. They should be stored in a boring and ventilated room and block both ends of the passage. 2. Forged steel valves should be checked regularly, and the dirt on them should be removed, and anti-rust oil should be painted on their appearance. 3. The forged steel valve after the device is applied should be repaired regularly to ensure its normal operation. 4. Check whether the sealing surface of the valve is worn or not, and repair or replace it according to the condition. 5. Check the wear condition of the trapezoidal thread of the valve stem and the valve stem nut of the forged steel valve, whether the packing is out of date and invalid, etc., and replace it if necessary. 6. The sealing performance of the valve should be tested to ensure its performance. 7. The valve in operation should be intact, the bolts on the flange and the bracket should be complete, the threads should not be damaged, and there should be no looseness. 8. If the handwheel is lost, it should be prepared in time and cannot be replaced by an adjustable wrench. 9. The packing gland is not allowed to be skewed or without pre-tightening gap. 10. If the valve is used in a harsh environment and is susceptible to rain, snow, dust, sand and other dirt, it should be a valve stem device protective cover. 11. The ruler on the forged steel valve should be intact, accurate and clear, and the valve should be sealed and capped. 12. Questions about depressions and cracks in thermal insulation forged steel valves. 13. Forged steel valve during operation, avoid hitting it or supporting heavy objects.
