Exhaust valve type carbon dioxide cracking pipe

Abstract

The invention discloses an exhaust valve type carbon dioxide cracking pipe. The exhaust valve type carbon dioxide cracking pipe is composed of a sealing plate, a pipe body, an electronic fuze, an airinlet pipe, an air inlet one-way valve, an exhaust pipe, an exhaust pipe valve and a heating pipe. According to the exhaust valve type carbon dioxide cracking pipe, an exhaust pipeline is arranged, full filling can be well conducted on the liquid carbon dioxide capacity, the blasting power of a single exhaust type cracking pipe can be well improved, when a power supply is switched on through the electronic fuze, the heating pipe effects quickly, thus carbon dioxide in an outer pipe is instantly vaporized and expanded, the pressure in the pipe is increased rapidly, the outer pipe is expanded and bursted, the whole detonation process is fast, the production efficiency is high, the exhaust valve type carbon dioxide cracking pipe is smashed at one time, and the blasting power is high.

Description

Technical field: [0001] The invention relates to the technical field of blasting devices, in particular to an exhaust valve type carbon dioxide cracking tube. Background technique: [0002] In the existing blasting technology, most of the blasting tubes are used to replace the traditional explosives during the blasting operation. The existing carbon dioxide blasting device, such as the carbon dioxide blasting device in the invention patent with application number 201520141713.X, has a top end of the blasting tube. A filling head with a filling hole. The filling head is provided with a valve core matching the filling hole and a terminal post matching the detonating device. The terminal post covered with an insulating tube is connected to the terminal screw. The tail of the blasting tube There is a venting head with a blasting hole and a decompression hole at the end, a bursting disc is set between the venting head and the blasting tube, the first wire passing through the vent...

[0002] In the existing blasting technology, most of the blasting tubes are used to replace the traditional explosives during the blasting operation. The existing carbon dioxide blasting device, such as the carbon dioxide blasting device in the invention patent with application number 201520141713.X, has a top end of the blasting tube. A filling head with a filling hole. The filling head is provided with a valve core matching the filling hole and a terminal post matching the detonating device. The terminal post covered with an insulating tube is connected to the terminal screw. The tail of the blasting tube There is a venting head with a blasting hole and a decompression hole at the end, a bursting disc is set between the venting head and the blasting tube, the first wire passing through the venting head, the blasting tube, and the filling head and the first wire connected to the shell of the blasting tube The two wires are respectively connected to the power supply and can be used repeatedly, but the directional blasting force is small, and it is difficult to meet the blasting requirements for large-scale external operations. If there is too much moisture, the cracking tube will not be fully inflated during the inflation process, resulting in a decrease in blasting power
