Abstract
The utility model relates to a pipeline pressure testing device which includes a pressure sensor, a display instrument, and a signal line. The pressure sensor is arranged in a pipeline and is connected with the external display instrument via the signal line. A housing of the pressure sensor is provided with a temperature reducing device. The pipeline pressure testing device is small in volume, is light in weight, is high in measurement precision, and is easy to use, can be reliably applied to the pipeline in a severe working environment, and at the same time, can visually display the pipeline pressure information.
Description
Technical field
The utility model relates to pressure test, relates in particular to a kind of pipeline pressure proving installation.
Background technology
Since pipeline carry have cost low, save the energy, safe and supply with the advantages such as stable, pipeline transportation is found broad application in all trades and professions, has become the indispensable ingredient of modern society.Pressure test is an important step in the pipeline transmission, but at present such as the air inlet wind pressure measurement, container tightness is measured, the combustion chamber draft force measurement, the occasions such as vacuum pump vacuum pressure measurement are not having reference pressure aspect the manual adjustments pressure, regulate accurately not, thereby need to when regulating pressure, can directly see current pipeline pressure, in order to reach regulating effect.And generally there is following characteristics in these pipelines: the measuring media temperature is high, generally more than 180 ℃; Measurement environment is full of moisture, and pipeline has the cigarette ash dust outward; Measurement range is at-800Pa～6000Pa.Therefore common measurement mechanism is difficult to reach requirement, has both needed sensor can adapt to above-mentioned abominable working environment, can have again digital reading to show that the aspects such as measuring accuracy also will reach the high detection requirement.
The utility model content
The shortcoming of prior art the object of the present invention is to provide a kind of pressure test device that is applied to high-temperature steam dust pipeline in view of the above, is used for solving the problems of the prior art.
Reach for achieving the above object other relevant purposes, the utility model provides a kind of pipeline pressure proving installation, comprise pressure transducer, Displaying Meter, signal wire, described pressure transducer is located in the pipeline and by the Displaying Meter of described signal wire with the external world and is connected, and described pressure sensor housing is provided with cooler.
Further, described pressure transducer adopts high temperature resistant diffuse si pressure-sensitive core body.
Further, described pressure sensor housing material is stainless steel.
Further, described Displaying Meter comprises Voltage-output module, electric current output module, communication module and alarm module.
By above technical scheme, the utlity model has following technique effect: this device volume is little, lightweight, easy to use, has high measurement accuracy, can be applied to reliably in the pipeline of abominable working environment, simultaneously the pressure information of energy display pipes directly perceived.

Fig. 1 is that the utility model pipeline pressure proving installation forms synoptic diagram.
The element numbers explanation:
The 1-pressure transducer;
The 2-signal wire;
The 3-Displaying Meter;
The 4-pipeline.
Embodiment
Below by particular specific embodiment explanation embodiments of the present invention, person skilled in the art scholar can understand other advantages of the present invention and effect easily by the disclosed content of this instructions.
See also Fig. 1.Notice, the appended graphic structure that illustrates of this instructions, ratio, size etc., equal contents in order to cooperate instructions to disclose only, understand and reading for person skilled in the art scholar, be not to limit the enforceable qualifications of the present invention, so technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, not affecting under the effect that the present invention can produce and the purpose that can reach, all should still drop on disclosed technology contents and get in the scope that can contain.Simultaneously, quote in this instructions as " on ", D score, " left side ", " right side ", " centre " reach the term of " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the present invention, the change of its relativeness or adjustment, under without essence change technology contents, when also being considered as the enforceable category of the present invention.
The utility model provides a kind of pipeline pressure proving installation, comprises pressure transducer 1, Displaying Meter 3, signal wire 2, and pressure transducer 1 is located in the pipeline 4 and by the Displaying Meter 3 of signal wire 2 with the external world and is connected.Pressure transducer 1 adopts high temperature resistant diffuse si pressure-sensitive core body, makes pressure transducer have high-precision signal output and resolution; The pressure sensor housing material is stainless steel, and present embodiment adopts the 316L stainless steel to make pressure sensor housing firmer, has simultaneously high rust-proof effect.The shell of pressure transducer is provided with cooler, though set up cooler so that pressure transducer in use medium temperature moment reaches the high-acruracy survey that 200 degree do not affect pressure transducer yet.Displaying Meter comprises Voltage-output module, electric current output module, communication module and alarm module, and adopts double-deck four high brightness greens and emitting red light charactron, and the pressure information intuitive display understands.
In sum, the utility model volume is little, lightweight, easy to use, has high measurement accuracy, can be applied to reliably in the pipeline of abominable working environment, simultaneously can display pipes pressure information directly perceived.So the present invention has effectively overcome various shortcoming of the prior art and the tool high industrial utilization.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not is used for restriction the present invention.Any person skilled in the art scholar all can be under spirit of the present invention and category, and above-described embodiment is modified or changed.Therefore, have in the technical field under such as and know that usually the knowledgeable modifies or changes not breaking away from all equivalences of finishing under disclosed spirit and the technological thought, must be contained by claim of the present invention.
