Method of assembling sealing ring

Abstract

The invention discloses a method of assembling a sealing ring. The method is realized by using a material taking rod, a jacket, an expansion sleeve, a push plate, a guide sleeve and a discharging sleeve, wherein the jacket is sleeved on the material taking rod; the jacket and the material taking rod can move along the axial direction relative to each other; the external diameter of the material taking rod is slightly larger than the internal diameter of the sealing ring and is smaller than the internal diameter of the jacket; the internal diameter of the jacket is smaller than the external diameter of the sealing ring; the discharging sleeve is sleeved on the guide sleeve; the discharging sleeve and the guide sleeve can move in the axial direction relative to each other; the external diameter of the guide sleeve is smaller than the internal diameter of the discharging sleeve; the internal diameter of the guide sleeve is larger than the external diameter of a receptor; the internal diameter of the discharging sleeve is smaller than the external diameter of the expanded sealing ring; the expansion sleeve can be opened axially or can be opened along the taper; when the expansion sleeve is closed, the outer contour of the expansion sleeve is smaller than the internal diameter of the sealing ring; when the expansion sleeve is opened, the outer contour of the expansion sleeve is larger than or equal to the external diameter of the guide sleeve; the material taking rod, the jacket, the discharging sleeve are located above the push plate and the expansion sleeve. The method of assembling the sealing ring is simple and convenient to operate, safe and reliable and strong in universality, and can be applied to semi-automation and automation equipment for assembling the sealing ring, so that the labor can be saved and the production efficiency can be improved.

Description

technical field [0001] The invention relates to an assembly method of a sealing ring, which can be applied to the assembly of sealing rings of valve stems of ball valves and angle valves. Background technique [0002] Sealing rings are widely used. At present, they are mainly assembled by manpower. The efficiency of assembly is low, the consumption of manpower is large, and the cost of manpower is high. Contents of the invention [0003] The object of the present invention is to provide a sealing ring assembly method, which is easy to operate, safe, reliable and highly common, and can be applied to semi-automated and automatic equipment for sealing ring assembly, so as to save manpower and improve production efficiency. [0004] see figure 1 , the method for assembling the sealing ring is realized by means of the retrieving rod 1, the overcoat 2, the expansion sleeve 3, the push plate 4, the guide sleeve 5, and the unloading sleeve 6; Relatively moving along the axial di...
