Manufacturing method of special tool for railway brake valve assembly

The utility model relates to a special tool for assembling a railway brake valve. Its technical points are as follows: a valve barrel arranged vertically, a top rod matched with the valve barrel, the valve barrel is a cylinder and the inner wall of the cylinder is provided with a clamp The groove is matched with the outer edge of the core valve. The number of valve barrels is two. The top ends of the two valve barrels are connected to the support seat. The top surface of the support seat is provided with two through holes corresponding to the centers of the two valve barrels. The number of ejector rods is two and the lower end of the ejector rod is inserted into the corresponding valve cylinder through the through hole. The upper ends of the two ejector rods are provided with a connecting plate. The length of the two valve cylinders is different, one is long and the other is short. Two ejector rods The length of the valve is different, and the ejector rod that extends into the longer-length valve barrel is longer than the other ejector rod. The tool solves the problem that the existing railway brake valve is easy to install the sandwich valve. The assembly of two sandwich valves for the same railway brake valve is completed at the same time, which is convenient and fast, and significantly improves the assembly efficiency. Significantly improve assembly efficiency. Significantly improve assembly efficiency.
