进口气动高温耐磨切断球阀美国阿卡迪亚品牌

进口气动高温耐磨切断球阀Product Description:

It includes a pneumatic box, in which a ball valve shaft is inserted, a base bearing is arranged at the bottom end of the ball valve shaft, the ball valve shaft is rotationally connected with the base bearing, the ball valve body is fixed on the ball valve shaft, arc bumps are fixed on both sides of the ball valve body, a sealing box is arranged on both sides of the ball valve body, a base bearing is arranged at the bottom of the sealing box, a flow pipe is fixed at one side of the sealing box, a ball connecting pipe is arranged inside the flow pipe, and the ball connecting pipe is engaged with the flow pipe, By improving the principle of fitting the ball and the ball valve cavity, the ball valve can still work normally under the fitting action of the straight cylinder spring in the high-temperature environment, after the ball is enlarged, it is fitted with the circular arc protrusion and the circular arc groove arranged at both ends of the ball.

进口气动高温耐磨切断球阀:

The principle of turning the ball valve shaft to drive the ball to rotate and cut off the fluid is widely used in practical life, and is often used to cut off the liquid transportation. However, the ball valve also faces various problems in practical application. Most of the balls are made of stainless steel. However, in the high-temperature transportation pipeline, the ball expands by heating, and the volume increases. When the ball rotates, A long time will cause the gap between the ball and the ball valve cavity to become large, resulting in liquid leakage.

进口气动高温耐磨切断球阀Principle:

The pneumatic high-temperature wear-resistant cut-off ball valve includes a pneumatic box. The inside of the pneumatic box is penetrated with a ball valve shaft. The bottom end of the ball valve shaft is provided with a base bearing. The ball valve shaft is rotationally connected with the base bearing. The ball valve body is fixed on the ball valve shaft. Arc bumps are fixed on both sides of the ball valve body. The sealing box is provided with a base bearing at the bottom of the sealing box. A flow pipe is fixed on one side of the sealing box. A ball connecting pipe is provided inside the flow pipe, The ball connecting pipe and the flow pipe are clamped and matched. A straight cylinder spring is arranged between the flow pipe and the ball connecting pipe. One side of the ball connecting pipe is provided with an arc groove, and an arc bump is arranged inside the arc groove. The principle of the device is to improve the ball valve body on the basis of the traditional round ball shape and add two arc bumps. When the ball valve body rotates, the arc bump is matched with the arc groove of the ball connecting pipe to realize flow cutoff, When the circular arc bump is separated from the ball connecting pipe, the quarter ring set on the ball valve body contacts with the circular arc groove to create a certain gap between the two. At this time, the pipe flows, and the ball connecting pipe is firmly pressed against the circular arc bump under the action of the straight cylinder spring, which ensures that the ball valve can cut off the flow of the pipeline ball valve after the heating volume becomes large.
