Abstract
The invention relates to a chock plug capable of protecting a pressure sensor from being ablated, comprising a pressure-measuring sensor chock plug, a pressure sensor installation groove and a pressure-measuring oil filling groove, wherein the pressure sensor installation groove is arranged in the pressure-measuring sensor chock plug, the pressure-measuring oil filling groove is arranged at one end of the pressure-measuring sensor chock plug and is communicated with the pressure sensor installation groove, the pressure-measuring sensor chock plug is provided with an external thread connected with a high-pressure closed container, and the inner wall of the pressure sensor installation groove is provided with an internal thread connected with a pressure sensor. By utilizing the device in the invention, the gas pressure can be measured under the high temperature condition, and the pressure sensor can not be damaged. The chock plug capable of protecting the pressure sensor from being ablated is utilized to measure the pressure-time curves during 200-time gunpowder combustion processes, then a pressure calibration machine is utilized to measure the pressure sensor, and the result shows that the pressure sensor can be normally used with good performance.
Description
Technical field
The present invention relates to a kind of chock plug of protecting the unburned erosion of pressure transducer.
Background technology
The method of gas pressure measurement is that gas acts directly on the pressure transducer at present, and in the ordinary course of things, pressure transducer is as long as periodic calibrating can repeatedly use.When materials such as gunpowder, explosive during in less high-pressure closed vessel internal combustion, can produce the high temperature more than 2000 ℃, if utilize pressure transducer directly to measure combustion-gas pressure this moment, will damage pressure transducer.
Summary of the invention
Technical matters to be solved by this invention provides a kind of gaseous tension of measuring under the hot conditions, and can not damage the chock plug of the unburned erosion of the pressure transducer protected of pressure transducer.
The present invention adopts following technical scheme:
The pressure measurement oil filling groove that is connected with the pressure transducer mounting groove that the present invention includes the load cell chock plug, is arranged on the pressure transducer mounting groove in the load cell chock plug and is arranged on load cell chock plug one end, described load cell chock plug is provided with the external thread that connects high-pressure closed vessel, and pressure transducer mounting groove madial wall is provided with the internal thread that connects pressure transducer.
Beneficial effect of the present invention:
Utilize apparatus of the present invention can measure gaseous tension under the hot conditions, and can not damage pressure transducer.Utilize the chock plug of the unburned erosion of sensor of the present invention, after having measured 200 pressure-time curves in the powder burning process, utilize the pressure calibration machine that pressure transducer is detected, pressure transducer is functional, can normally use.
