Problems solved by technology

Existing explosion protection mostly uses dry-type flame arresters, explosion vents, anti-tempering, explosion suppression devices, etc. These technologies can be applied to different protection requirements, but there is a risk of failure to block explosions due to overfire. In order to achieve effective physical resistance It is necessary to use a valve-type shut-off transmission device, and the existing valves are usually manual or electric, but the closing time is long, and they do not have the explosion-proof effect in terms of explosion protection.
[0003] In addition, the existing valve cannot be reset after blocking the explosion. It needs to be disassembled and reinstalled to realize pipeline ventilation. On the one hand, it is not conducive to the rapid recovery of production, on the other hand, it increases the production cost input

Abstract

The invention discloses an explosion blocking and venting device for a pipeline, belongs to the technical field of gas conveying safety protection, and provides the explosion blocking and venting device with millisecond-level stopping and convenient reset. According to the technical scheme, the explosion blocking and venting device for the pipeline comprises a device main body, a front supportingframe, a rear supporting frame, a sealing plate, a spindle, a sealing ring and a reset device; and the device main body is of a tubular structure with the two ends open, the front supporting frame andthe rear supporting frame are fixed into the device main body and each composed of a plurality of straight rods and pipe sleeves fixed to the middles of the straight rods, the sealing plate is arranged between the front supporting frame and the rear supporting frame and provided with the spindle, the spindle penetrates through the pipe sleeves and can slide in a reciprocating mode relative to thepipe sleeves, the sealing ring is arranged on the inner wall, between the front supporting frame and the sealing plate, of the device main body, the sealing plate and the sealing ring mutually cooperate, and the reset device is arranged on the spindle and can adjust the spindle to operate in a reciprocating mode along center lines of the pipe sleeves.

Description

technical field [0001] The invention relates to an explosion blocking and releasing device for a pipeline, which belongs to the technical field of gas transportation safety protection, and in particular relates to an explosion preventing device for a gas pipeline. Background technique [0002] At present, whether it is natural gas, gas, coal bed methane, hydrogen, combustible dust, chemical gas and other flammable and explosive media pipeline transportation, there is a need for explosion safety protection. Existing explosion protection mostly uses dry-type flame arresters, explosion vents, anti-tempering, explosion suppression devices, etc. These technologies can be applied to different protection requirements, but there is a risk of failure to block explosions due to overfire. In order to achieve effective physical resistance It is necessary to use a valve-type shut-off transmission device, and the existing valves are usually manual or electric, but the closing time is long...
