The structural features of an all-welded ball valve

An all-welded ball valve is used in a wide variety of applications. It has superior quality and high performance stability that general cast steel ball 体彩排列5走试图 cannot achieve. Its service life is far longer than cast steel ball valves. An all-welded ball valve is widely used in urban gas, urban heat supply, petrochemical industry, shipbuilding, steel, pressure regulating stations, power plants and other types of pipeline equipment. The all-welded ball valve can be used for reliable long-term operation, which requires simpler maintenance and easier installation than any other ball valves.

Structural features of an all welded ball valve
1. An all-welded ball valve has an advanced valve seat: It is designed with many years of experience in ball valve manufacturing. It has low friction coefficient and small operating torque. Moreover, the valve seat can be made of various materials. The all-welded ball valve has a wide range of application.

2. Anti-flying structure of valve stem of an all welded ball valve: Steps are arranged at the lower part of the valve stem, and the valve stem is installed below the inside of the valve body to prevent the valve stem from flying out.

3. Anti-static function of an all-welded ball valve: An anti-static spring is arranged between the ball and the valve body or the valve stem to discharge the static electricity generated during the switching action.

4. Fire proof structure of an all welded ball valve: with advanced fire proof design, after the fire, each leaking part is designed in flexible graphite packing or stainless steel mix graphite to meet the requirement of fire resistance.

5. Handle operation of an all-welded ball valve: the flat head stem is used, and the connection with the handle is not misaligned, thus ensuring that the switch state indicated by the handle is consistent with that of the valve. In order to prevent the valve switch from malfunctioning, locking holes are provided in the fully open position and the fully closed position of the switch to ensure that the valve is in the correct position.
6. An all-welded ball valve adopts the most advanced support plate structure at home and abroad, which improves the service life of the valve, reduces the operating torque of the valve, and greatly prolongs the service life of the valve.
