Equipment used in plants for sleeving valve rods with rubber rings

Abstract

The invention discloses equipment used in plants for sleeving valve rods with rubber rings. The equipment comprises a base, wherein a working cavity is formed in the base, a motor is embedded in the working cavity, and is in power connection with a motor shaft, two one-way bearings which are installed reversely and have optional directions are arranged on the motor shaft, and a lifting assembly capable of controlling a valve rod and a rubber ring to lift and fall is arranged on the one-way bearing at the front side. According to the equipment used in plants for sleeving valve rods with rubberrings, the one-way bearings are adopted, so that power switching among different assemblies is achieved, and the arrangement of power sources is reduced; a detection assembly is adopted, so that whenit is detected that the rubber ring is expanded to the maximum extent, expansion is immediately stopped to prevent the rubber ring from being broken under expansion; a spring and a cable are adopted,thus the rubber ring is enabled to move left and right, and the current situation that at present, for most equipment for sleeving valve rods with rubber rings, the forces of expanding the rubber rings during ring sleeving each time are the same, so that the rubber rings of different sizes are inconvenient to expand, and are also liable to get broken under expansion, and then sealing cannot be achieved is avoided.

Description

technical field [0001] The invention relates to the field of valve stem collars, in particular to valve stem collar equipment in a factory. Background technique [0002] The valve stem, as one of the main parts of the ceramic valve core, plays the role of connecting up and down rotation and controlling the work of the ceramic piece. At the same time, the rubber ring on the valve stem plays a good sealing role. The valve stem ferrule equipment currently on the market , it is generally used to stretch the rubber ring and put it into the valve stem, but most of the valve stem ferrule equipment has the same strength to stretch the rubber ring every time, which not only makes it inconvenient to stretch the rubber rings of different sizes , and it is easy to crack the ring, resulting in inability to seal. A device that can solve the above-mentioned problems is explained by the present invention. Contents of the invention [0003] technical problem: [0004] At present, most of...
