Gas sealing device

Abstract

The invention discloses a gas sealing device which comprises a gas storage tank; a sealed cover is arranged at the top of the gas storage tank, and comprises a gas inlet pipe, an upper cover, fixing screws and a lower cover; the gas inlet pipe is arranged at the top of the upper cover; the fixing screws are symmetrically arranged on the left side and the right side of the upper cover, the bottom of each of the fixing screws penetrates through the upper cover and is in threaded connection with the gas storage tank; the lower cover comprises a rubber ring, a ventilation ball and a fan ring block; the ventilation ball is connected with an inner ring of the fan ring block; an outer ring of the fan ring block is connected with the rubber ring; the ventilation ball comprises a first ventilating opening, a connecting belt, an outer ventilation ball, an inner ventilation ball and a second ventilating opening. According to the gas sealing device disclosed by the invention, by the comprehensive use of a buffer and a buffer spring, the safety guarantee of production is enhanced; by using the buffer, the gas storage tank is protected, so that the service life of the gas sealing device is prolonged; by using a manometer, a user can observe the situation of gas pressure in the gas storage tank at any moment.

Description

technical field [0001] The invention relates to the technical field of sealing, in particular to a gas sealing device. Background technique [0002] The gas sealing device is a device that prevents external impurities from contaminating the internal gas. When the traditional gas sealing device is filled with gas, the excessive pressure given to the device in a short period of time may cause the device to burst, thereby bringing potential risks to production. Potential safety hazards, the excessive pressure of the gas sealing device in a short period of time will cause a certain degree of damage to the components of the device, thereby shortening the service life of the gas sealing device and increasing the production cost. Contents of the invention [0003] The purpose of the present invention is to provide a gas sealing device to solve the problems raised in the background art above. [0004] In order to achieve the above object, the present invention provides the follow...
