Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

Referring to fig. 1-3, in a first embodiment of the present utility model, a safety device for a kerosene and gas pipeline is provided, which includes a housing 11, an open fire blocking net 12 is installed at the left end and the right end in the housing 11, a pressure release body 14 which is communicated with the housing 11 is fixedly connected with the housing 11, two blocking sliders 13 are slidably connected with the housing 11, two blocking sliders 13 are provided with through holes, the axial positions of the two through holes are staggered, a selection block 15 is slidably connected with the pressure release body 14, the left end and the right end of the selection block 15 are connected with the two blocking sliders 13 through a connecting rope 16, a polish rod 18 is fixedly connected with the blocking sliders 13 in a sliding manner, one surface of the blocking sliders 13 close to the open fire blocking net 12 is fixedly connected with the connecting rope 16, two pressure release holes which are symmetrical in position are provided on the selection block 15, the pressure release holes are the same as the inner diameter of the pressure release body 14, the connection body 14 is slidably connected with the two blocking sliders 13, and the pressure release rod 18 is fixedly connected with the housing 11 through the connecting rope 17.

Working principle: when explosion does not occur, the two blocking sliding blocks 13 are conveniently located at two ends in the shell 11, evaporated kerosene gas can pass through the through holes of the blocking sliding blocks 13, the selection block 15 is located in the middle in the pressure release body 14, the pressure release body 14 is closed, and the kerosene gas cannot pass through the pressure release body 14.

When explosion happens, open fire generated by the explosion can be blocked by the open fire blocking net 12, air flow generated by the explosion can push the blocking slide blocks 13 firstly, the shell 11 prevents the blocking slide blocks 13 from rotating in the moving process, so that the two blocking slide blocks 13 are overlapped, through holes on the two blocking slide blocks 13 are closed, impact air flow generated by the explosion cannot pass through the shell 11 to impact a transportation pipeline connected at the back, the blocking slide blocks 13 can pull the selection blocks 15 through the connecting ropes 16 in the moving process, pressure release holes of the selection blocks 15 are aligned with holes of the pressure release bodies 14, through holes in the pressure release bodies 14 are opened, and air flow generated by the explosion can be released through the pressure release bodies 14.
