Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gas analyzers, in particular to a flame arrester filter element for a gas analyzer. Background Art
[0002] Flame arresters are safety devices used to prevent the spread of flames of flammable gases and flammable liquid vapors. They are generally installed in pipelines that transport flammable gases or on ventilated tanks to prevent the spread of flames (deflagration or detonation). They are composed of a flame arrester core, a flame arrester shell and accessories. Flame arresters are also commonly used on pipelines that transport flammable gases. If the flammable gas is ignited, the gas flame will spread to the entire pipe network. In order to prevent this danger from occurring, flame arresters must also be used. Flame arresters can also be used on pipelines with open flame equipment to prevent flashback accidents. However, it cannot prevent the open flame combustion of flammable gases and liquids that are burned in the open. Existing flame arrester filters have the problem of small air flow and inconvenient installation.
[0003] The application number is 202123172349.8, which discloses a fire-blocking filter that is easy to connect, including a flame arrester connector, a flame arrester housing and a flame arrester core. One end of the flame arrester connector is fixedly connected to the flame arrester housing, and one end of the flame arrester housing is movably connected to a connecting circular plate. The connecting circular plate is fixedly connected to a fixing mechanism, and a supporting mechanism is arranged at the lower end of the flame arrester housing. For this fire-blocking filter that is easy to connect, the fire arrester core usually needs to be regularly inspected and maintained after being used for a period of time. If the fire arrester core is found to be damaged, it can be replaced in time. When replacing the fire arrester core, the bolts fixed at the threaded holes are manually removed, and then the two groups of threaded holes and the connecting circular plate are pushed outward. The fixing block fixed on the outside of the connecting circular plate moves outward along the limit groove, so that the fire arrester core arranged at the core groove can be easily removed. Through this fixing method, the problem that the traditional flame arrester connector and the flame arrester housing are difficult to disassemble after fixing the fire arrester core is solved.
[0004] However, there is a disadvantage that the flame arrester filter element is arranged outside the screw hole, and the gap between the filter element and the screw hole is large, which will lead to a small air flow. Utility Model Content
[0005] The utility model aims to provide a flame arrester filter for a gas analyzer to solve the problem in the background art that the flame arrester filter is arranged outside the screw hole and the gap between the filter and the screw hole is large, which leads to a small air flow.
[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:
[0007] The utility model discloses a flame arrester filter element for a gas analyzer, comprising a stainless steel element, the inner side of which is movably connected to the filter element, the outer side of which is provided with a first thread, and the inner side of which is provided with a second thread.
[0008] The utility model has the following beneficial effects:
[0009] (1) The utility model provides a first thread and a second thread on the inner and outer sides of the stainless steel part, so as to facilitate the connection of the external parts, and the filter is tightly fitted on the inner side. By tightly fitting the filter on the inner side of the stainless steel part, the gap between the filter and the stainless steel part is reduced, so that the filter has better flowability when filtering air.
[0010] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] In order to more clearly illustrate the technical solutions of the embodiments of the utility model, the drawings required for describing the embodiments are briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.
