Technical characteristics and functions of forged steel ball valves
The forged steel ball valve utilizes the principle of the cam, so that the valve ball is disengaged from the sealing surface of the valve seat during rotation, and then the ball is pushed to the valve seat to achieve sealing after being rotated. When the forged steel valve is in the fully open position, turn the handwheel clockwise, the stem nut and the thrust bearing cooperate, the valve stem begins to descend and the ball rotates.
The forged steel ball valve is connected to the rotating hand wheel, and the precise spiral curve groove track on the valve stem interacts with the guide pin embedded therein to drive the ball to rotate clockwise with the valve stem. When the forged valve is about to close, the valve stem rotates the ball and the seat sealing surface completely without friction and rotates ninety degrees. Clean the forged steel ball valve every other year, so that the valve seat cavity is not polluted, the valve seat can move freely, and at least an appropriate amount of grease is injected into the switch every year to reduce the ball and seat gluing and the friction between the ball and the valve seat. , reducing unnecessary losses.
Because the material of the forged steel ball valve body is the same as that of the pipe material, uneven stress will occur, and it will not be deformed due to earthquake and vehicle passing through the ground. The pipe is resistant to aging, and the sealing ring body is made of PTFE material to ensure no leakage. There are no external leaks and other phenomena. The forged steel ball valve stem can be lengthened according to the user's specific installation conditions, so as to facilitate the ground operation. Compared with the conventional ball valve of the same specification, it has the advantages of small size, light weight, beautiful appearance and durability. According to different media, the material of the seat sealing surface of the forged steel ball valve can be PTFE, nylon, alloy steel, hard alloy, etc., which can adapt to a relatively wide range of different temperature, pressure and corrosion requirements.
Together with the good technical characteristics of the forged steel ball valve, welding the whole gas pipeline can enhance the overall stress resistance of the pipeline, avoid the possibility of gas leakage, and prolong the reliability life of the forged valve, which is conducive to the installation and maintenance of the daily ball valve.
