Problems solved by technology
The applicant found that the following problems existed in the use of the explosion pressure gauge: due to the need for manual hand-held explosion pressure gauges to perform repeated disassembly and assembly work on the detection port of each cylinder, the air flow of the explosion will transfer a higher temperature For the explosion pressure gauge, it is inconvenient for the operator to disassemble and assemble. At the same time, the high temperature will damage the internal structure of the detection gauge and reduce the service life of the explosion pressure gauge.

The invention discloses an explosion pressure gauge heat insulation structure. The structure comprises a holding member and a cooling assembly. The cooling assembly comprises a first cooling pipe anda second cooling pipe, the first cooling pipe is detachably arranged at one end of the holding member, the holding member is provided with a heat dissipation cavity connected with outside air, and thesecond cooling pipe is arranged in the heat dissipation cavity. The holding member is arranged on an outer side of the cooling assembly, heat conduction of a burning and explosion airflow is isolated, and stability of the holding member is reduced so that operation of a user is convenient; and the holding member can be used as a support of a whole structure, structural strength of an explosion pressure gauge can be improved, the explosion pressure gauge is prevented from being damaged during disassembling, meanwhile, a capillary tube is adopted to further cool the burning and explosion airflow to the detection gauge, damage of a high temperature to the detection structure of the detection gauge is reduced, and a service life of the detection gauge is prolonged.
Description
technical field [0001] The invention relates to the field of heat insulation structures of explosion pressure gauges, in particular to a heat insulation structure of explosion pressure gauges. Background technique [0002] The explosion pressure gauge is a device used to detect the airflow pressure when the cylinder of the internal combustion engine explodes, especially for large and medium-sized diesel engines. The applicant found that the following problems existed in the use of the explosion pressure gauge: due to the need for manual hand-held explosion pressure gauges to perform repeated disassembly and assembly work on the detection port of each cylinder, the air flow of the explosion will transfer a higher temperature The explosion pressure gauge makes it inconvenient for the operator to disassemble and assemble. At the same time, the high temperature will damage the internal structure of the detection gauge and reduce the service life of the explosion pressure gauge. ...
