进口高温硬密封固定球阀美国阿卡迪亚品牌

进口高温硬密封固定球阀Product Description:

The utility model comprises a valve body, a valve seat, a sphere, a stuffing box, an upper valve rod and a lower valve rod. The valve seat and the sphere are arranged in the valve body, and the sphere is matched with the valve seat to form a seal; The stuffing box is arranged on the valve body, one end of the upper valve rod passes through the stuffing box and the valve body in sequence and is connected with the upper end of the ball, and the lower valve rod is connected between the lower end of the ball and the valve body; A first bearing assembly is arranged between the upper valve stem and the stuffing box, a second bearing assembly is arranged between the upper valve stem and the valve body, and a third bearing assembly is arranged between the lower valve stem and the ball.

进口高温硬密封固定球阀characteristic:

The hard sealed fixed ball valve works at high temperature for a long time. The shaft sleeve and stem thrust gasket between the valve stem and the valve body, the valve stem and the stuffing box, the lower valve stem and the ball are made of stainless steel nitriding or stainless steel inner cavity surfacing. In this design scheme, when the valve is opened and closed, the shaft sleeve and stem thrust gasket between the valve stem and the valve body, the valve stem and the stuffing box, the lower valve stem and the ball are metal to metal sealed, with large friction and easy to bite, resulting in the increase of valve torque, the increase of actuator selection and the increase of valve volume, resulting in the high cost of the valve.

进口高温硬密封固定球阀Principle:

For the high-temperature hard sealed fixed ball valve, the first shaft sleeve, the second shaft sleeve, the third shaft sleeve and the thrust pad adopt sintered graphite material to replace the stainless steel material in the prior art, which is conducive to reducing the friction coefficient, reducing the friction and maintaining the same strength, so as to further reduce the valve torque; The stone burning ink material also has the advantages of high temperature resistance and high strength.
