Process for making double-magnetic-repulsion gas safety valve of motor

Abstract

This invention discloses a manufacturing technology for gas safety valves of a magnetic dual-thrust motor including the following steps: a, providing a primary alnico shift guide-way matched to the groove on the primary at the place opposite to motor box and the primary alnico, b, providing a system connector to connect and fix the motor box and a valve, c, providing a sub-alnico shift guide-way by a connecting bolt under the system connector and an inverted repulsion alnico is set at its bottom, d, a U-shape matcher with the sub-alnico is provided out of it, in which, the opposite faces of the primary and the sub-alnicos are homopolar and the opposite faces of the sub-alnico and the inverted-repulsion alnico are also homopolar. Since the motor and gas are isolated completely, it stops the contact of electric sparks with gas when the motor is working to avoid burning or explosion caused possibly.

Description

Technical field: [0001] The invention belongs to the technical field of valve manufacturing, and in particular relates to a manufacturing process of a safety valve used in pipelines of inflammable and explosive gases, measuring instruments and the like. Background technique: [0002] At present, the commonly used gas valve, because the gas channel and the motor box are not separated, so the electric spark generated when the motor is working, once it comes into contact with flammable and explosive gas, it is very easy to cause combustion and explosion accidents, which is harmful to the safety of people's lives and property. pose a serious threat. At the same time, limited by the structure of this type of valve, the valve opening stroke is relatively short, resulting in relatively large pressure loss, and because the end cover of this type of valve swings relatively large, resulting in a high failure rate. Invention content: [0003] The object of the present invention is t...
