Drawings

The invention will be further described with reference to the following figures and examples:

fig. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic diagram of a second core body of the present invention.

Detailed Description

Fig. 1 is a schematic structural diagram of the present invention, and as shown in the figure, the fuel gas filtering device in this embodiment includes an upper joint 4, a lower joint 8, a mounting seat 6 and a filter element; the filter element is fixedly arranged in the mounting seat 6; the upper joint 4 and the lower joint 8 are respectively connected to the top and the bottom of the mounting seat 6 through threads; the filter element comprises a shell 10, a first core 3 and a second core 5; the shell 10 is of a cylindrical structure, a partition plate is arranged in the middle of the shell and is separated by the partition plate to form a first cavity and a second cavity, and a through hole through which air flows is formed in the partition plate; the first core 3 and the second core 5 are respectively arranged in the first cavity and the second cavity; the upper joint 4 and the lower joint 8 are both of circular tube structures, a flow channel 1 is arranged in the upper joint, after the upper joint 4 is connected with the mounting seat 6 through threads, a cavity is formed in the upper joint and the mounting seat, and the whole filter element is positioned in the cavity; the gas accessible top connection 4 gets into and flows out from lower clutch 8, and at this in-process, the gas will flow through first core 3 and second core 5 and realize filtering, effectively avoids user's gas pressure unstability, and gas combustion flame is impure, and tiny iron powder passes the filter screen and causes the gas filtering device that user's gas equipment damaged and product quality destroys.
