H44H, H44Y, H64H, H64Y cast steel swing check valve
The function of H4 (6) 4H/Y check valve is to control the one-way flow of the valve in the pipeline to prevent the backflow of the medium in the pipeline. The check valve belongs to the active valve, and the headstock is opened or closed by the power of the flowing medium. The check valve is only used for one-way flow of media, and prevents backflow of media to prevent accidents. It is mainly used in petroleum, chemical, pharmaceutical, chemical fertilizer, electric power and other pipelines.
Characteristics and benefits
The design and manufacture of the products meet the requirements of the American national standard ANSI B16.34 and the American Petroleum Society Standard API6D
The valve pressure parts using the fine casting casting process, the appearance quality of appearance, no sticky sand, cold partition appearance defects; internal quality is stable, no loose, trachoma, cracks and other defects.
The swing check valve with built-in rocker swing structure, all opening and closing parts are arranged in the valve body of the valve, the valve does not penetrate, in addition to the sealing gasket or sealing ring for sealing flange parts, group no leakage point, put an end to the valve leakage may.
The connecting structure of the rocker valve and the valve clack of the swing check valve adopts a spherical connection structure, so that the valve has a certain degree of freedom in the range of 360 degrees centigrade, and has the appropriate micro position compensation.
The swing check valve seal sealing surface (13Cr) stack welding steel or hard alloy Stellite6, which is not used in fine particulate medium due to erosion and wear quickly and.

Gear Hobbing machine is one of the most widely used machine tools in gear processing, can cut straight teeth, helical teeth, cylindrical gear, but also can process worm gear, sprocket and so on. Gear hobbing machine is divided into vertical and horizontal two types according to the layout. Large and medium-sized hobbing machine for vertical, small gear hobbing machine and dedicated to processing long shaft gear hobbing machine are horizontal. Vertical gear hobbing machine is divided into two kinds of table movement and column movement.
