Technical field
The invention belongs to the device for pressure measurement field, especially a kind of device for pressure measurement that is applied under the non-standard atmospheric pressure environment.
Background technology
Along with the economic develop rapidly of China; Urbanization process is further accelerated; City size enlarges day by day; Underground construction is more and more frequent; Especially use shield machine excavation subterranean tunnel; When using shield machine; For construction safety; Usually to monitor shield machine pressure inside situation; Especially observe the pressure condition in personnel control room of living in and monitored control room; And the general criteria of right and wrong atmospheric pressure environment all in these two control rooms; The device for pressure measurement of common application under the standard atmospheric pressure environment is to be the instrument that benchmark is used to measure normal pressure with the atmospheric pressure; If this kind manometer is applied under the non-standard atmospheric pressure environment, can produce the additive error suitable with deviation value.Cause reading inaccurate, influence the judgement of observation personnel to monitored pulpit pressure condition, potential safety hazard is bigger.
, prior art finds a contrast file in being retrieved; Its patent No. is 200420013049.2; Patent name is many bourdon gaugess; Granted publication number is CN2760529Y; The applying date is on Dec 25th, 2004; The many bourdon gaugess of this documents disclose and have comprised support; Movement; At least two C type bourdon tubes; Movement comprises at least one group of gear drive; Inside and outside design is side by side adopted in the laying of at least two C type bourdon tubes in this documents; Major function is the force value that realizes through a plurality of equipment under tests of gauge measurement; Just reaching under the prerequisite of identical function; The tensimeter volume of this documents is littler; Structure is compact more, illustrates that it can be measured with the normal atmospheric pressure is the numerical value of benchmark but have no under non-standard atmospheric pressure environment.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art; A kind of device for pressure measurement that is applied under the non-standard atmospheric pressure environment is provided; This apparatus structure is simple, design science reasonable, cost is lower, can under non-standard atmospheric pressure environment, accurately measure the detected space internal pressure value.
The present invention solves its technical matters and realizes through following technical scheme:
A kind of device for pressure measurement that is applied under the non-standard atmospheric pressure environment; Comprise housing; The measuring spring pipe; Connecting rod; Gear drive; Pointer and dial plate; The stiff end of measuring spring pipe is packed in the housing; The mobile terminal of measuring spring pipe is through connecting rod driven wheel gear train; Pointer is packed on the central shaft of gear drive; Dial plate be packed in the corresponding housing of pointer in; It is provided with a counterbalance spring pipe in the position with measuring spring pipe symmetry; The mobile terminal of this counterbalance spring Guan Yiduan and measuring spring pipe installs; The stiff end of the other end of this counterbalance spring pipe and measuring spring pipe installs, seal standard atmospheric pressure in this counterbalance spring pipe.
And described measuring spring pipe and counterbalance spring pipe are symmetrical set with the line of centres between measuring spring pipe stiff end and the mobile terminal.
And described measuring spring pipe is all identical with the mechanical property and the geometric configuration of counterbalance spring pipe.
And, a pressure being set on the stiff end of described measuring spring pipe importing port, this pressure imports port and is communicated with the measuring spring pipe.
Advantage of the present invention and beneficial effect are:
1; The device for pressure measurement that should be used under the non-standard atmospheric pressure environment is provided with a counterbalance spring pipe in the position with measuring spring pipe symmetry; The mobile terminal of this counterbalance spring Guan Yiduan and measuring spring pipe installs; The stiff end of the other end of this counterbalance spring pipe and measuring spring pipe installs; Seal standard atmospheric pressure in this counterbalance spring pipe; This kind structure can effectively be measured the pressure of equipment under test under the non-standard atmospheric pressure environments; Especially counterbalance spring pipe and measuring spring pipe is symmetrical set; Their physical dimensions are identical; Mechanical characteristic is identical; Under non-standard atmospheric pressure environments; The additonal pressure error size that produces equates; Direction is opposite; Act on the mobile terminal simultaneously and cancel each other, eliminated working environment and departed from the measuring error that standard atmospheric pressure produces.
2, the measuring spring pipe and the counterbalance spring pipe that should be used for the device for pressure measurement under the non-standard atmospheric pressure environment is symmetrical set with the line of centres between measuring spring pipe stiff end and the mobile terminal; The measuring spring pipe is all identical with the mechanical property and the physical dimension of counterbalance spring pipe, and this kind structure has ensured to offset from environment and departed from the measuring error that standard atmospheric pressure produces.
3, should be used on the stiff end of measuring spring pipe of the device for pressure measurement under the non-standard atmospheric pressure environment pressure being set and import port, this pressure imports port and is communicated with the measuring spring pipe, and the setting of this kind structure is convenient for measuring.
4, the present invention is simple in structure, design science is reasonable, cost is lower, can under non-standard atmospheric pressure environment, accurately measure the detected space internal pressure value, is a kind of safe and reliable device for pressure measurement under the non-standard atmospheric pressure environment that is applied to.
