Abstract

A special valve for stone and pulverized coal comprises a metal valve body, a left flange, a right flange, a valve seat hole and a valve seat, wherein the left flange and the right flange are connected to the two ends of the metal valve body, the valve seat hole is formed in the left flange, and the valve seat is arranged in the valve seat hole. A valve rod hole is formed in the center of the side wall of the top end of the metal valve body, and a valve rod is arranged in the valve rod hole. The top end of the valve rod is connected with a pneumatic executing mechanism. The bottom end of the valve rod is connected with a spring base. The spring base comprises a horizontal pipe and a vertical threaded rod arranged in the center of the side wall of the horizontal pipe. The threaded rod is in screw joint with a threaded hole in the bottom end of the valve rod. A spring, a left supporting ejector rod and a right supporting ejector rod are arranged in the horizontal pipe, and the left supporting ejector rod and the right supporting ejector rod are arranged at the two ends of the spring in a sleeving manner. The horizontal pipe is inserted in a counterbore formed in the center of a disk-shaped gate plate. The left supporting ejector rod is pressed on the bottom face of the counterbore. The disk-shaped gate plate is matched with the valve seat. The right end of the horizontal pipe is inserted in a connecting sleeve. The service life of the valve is long, safe and stable running of production and management enterprises can be guaranteed, and good economic benefits are obtained.

Description

Technical field [0001] The invention belongs to the technical field of general mechanical valves, and particularly relates to a special valve whose medium is stone and coal powder. Background technique [0002] The valve is a control component in the pipeline fluid conveying system, used to change the passage section and the flow direction of the medium. It has the functions of diversion, cut-off, throttling, check, diversion or overflow pressure relief, and it is widely used. Traditional valves have strong versatility, but there are many types of finished products, and their production processes are ever-changing. The application of general valves is greatly restricted. The invention is mainly used for a special valve whose medium is pebbles and coal powder. It re-optimizes the design of the valve according to the particularity of the medium, and makes breakthroughs in material and structure. Summary of the invention [0003] The purpose of the present invention is to improve th...
