Detailed Description
The following description of the preferred embodiments of the present invention is provided for the purpose of illustration and description, and is not intended to limit the invention.
Example 1
As shown in fig. 1, an automatic antiknock explosion venting device comprises a main vent pipe 7 and a bypass pipe 8, wherein the main vent pipe 7 is sleeved on a non-pressure-bearing branch pipe of a gas pipe, and the diameter of the main vent pipe is larger than that of the non-pressure-bearing branch pipe of the gas pipe; a first fireproof ventilation cap 1 is installed at a pipeline opening at the top of the main ventilation pipeline 7 and is used for preventing and stopping all fire sources from passing through the first fireproof ventilation cap, so that the balance of internal and external pressure of the pipeline is ensured; an anti-explosion baffle 2 is installed inside the main vent pipeline 7, the anti-explosion baffle 2 is horizontally arranged inside the main vent pipeline 7, a baffle fixing shaft 4 is connected to the lower side surface of the anti-explosion baffle 2, an anti-explosion spring 3 is sleeved on the outer side of the baffle fixing shaft 4, a sleeve 6 is connected to the lower end of the baffle fixing shaft 4, and a sleeve explosion venting port 5 is formed in one side of the sleeve 6; be equipped with the baffle base in the sleeve 6, when antiknock spring 3 is compression state, antiknock baffle 2 is located on the baffle base, just sleeve explosion vent 5 with by pass line 8 is linked together.
When the explosion shock wave that produces when adjacent oil storage, gas storage, fuel, gas pipeline explode destroys top fire prevention ventilation cap, the breather pipe is perhaps gone into to high-pressure gas and flame, this moment: the anti-knock shutter 2 will act downwards compressing the anti-knock spring 3 as shown in figure 2. Meanwhile, the anti-explosion baffle 2 is overlapped with the baffle base to seal the main vent pipe, so that flame or shock waves cannot enter oil storage and gas storage equipment facilities, and secondary disasters cannot be caused. In the process, the sleeve and the anti-explosion baffle 2 move simultaneously, and when the anti-explosion baffle 2 is superposed with the baffle base, the sleeve explosion venting port is communicated with the explosion venting vent pipe to guide shock waves or flames to a safety area.
