Abstract
The utility model relates to a novel pressure intensity sensor, which is composed of a connecting component and a cylinder body, wherein the connecting component is provided with a fluid body inlet fixedly sealed with a sealing box of a measured fluid body and a fluid body outlet of the connecting component is communicated with the sealing box of the fluid body. The utility model is characterized in that the inner part of the cylinder body is provided with a corrugated pipe, the outer side of the corrugated pipe is fixedly sealed with the cylinder body and the inner side of the corrugated pipe is communicated with air. The upper end of the corrugated pipe is fixed with one end of a pressure output rod, and the other end of the pressure output rod extends out from the cylinder body. The utility model combines a valve and the pressure intensity sensor into integration. When the inner part of the sealing box of the fluid body is filled with liquid, the corrugated pipe senses the inner pressure intensity of a box body, converts the pressure intensity difference with the atmosphere into mechanical displacement and outputs the pressure difference by the pressure output rod. The output displacement of the pressure output rod of the utility model and the inner and outer pressure difference of the corrugated pipe are in direct proportion. When output displacement quantity is zero, one pa of atmosphere pressure intensity is displayed.
Description
Technical field
The utility model belongs to a kind of surveying instrument, particularly a kind of novel pressure transducer.
Background technology
Fluid pressure sensor on the market exists following defective: a, substances to be measured physical state to have limitation at present, and fluid pressure sensor on the market is only applicable to the measurement of gas or liquid; B, employing rubber seal, the easy ageing failure of rubber, sealing not exclusively the bad leakage phenomenon that causes often occurs sealing, and needs the periodic replacement seal, the work of increase management maintenance; C, element are installed and are had limited space, both have been not suitable for remote monitoring; When there are space angle difference in measured point and indicating positions, be not easy to realization, d, when there are space angle difference in remote monitoring or measured point with indicating positions, all adopt rubber tube to be connected, both increase seal point, also limited the defectives such as upper pressure limit of detected body.
Summary of the invention
The purpose of this utility model provides a kind of novel pressure transducer complete, the energy remote monitoring that seals, to overcome above-mentioned deficiency.
To achieve these goals, the utility model is made of web member and cylinder body, wherein web member is provided with the import with the fluid surveyed, the fluid egress point of web member communicates with cylinder body, be characterized in being: in cylinder body, be provided with a corrugated tube, the outside of corrugated tube and cylinder body sealing and fixing, corrugated tube is inboard to communicate with air, one end of the upper end fixation pressure take-off lever of corrugated tube, the other end of pressure take-off lever stretches out outside cylinder body.
The utility model gas collection valve, baroceptor are in one, adopt the totally enclosed type technology, do not increase any leakage point, when the gas storage box house charges into gas, gas enters in the utility model simultaneously, corrugated tube is experienced box house air pressure and its pressure is converted to mechanical shift, and by the output of air pressure take-off lever, the reflection air pressure inside changes.The utility model air pressure take-off lever output displacement is directly proportional with the casing internal gas pressure, and promptly air pressure inside is high more, and its output shift quantity is big more; When output shift quantity is zero, represent that promptly atmospheric pressure state is gone at the place in the casing.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing.
The utility model as shown in the figure, cylinder body 1 inner fluid directly is communicated with detected fluid in the casing by web member 2, fluid passage, corrugated tube 3 is sealed in the cylinder body 1, fluid isolation in corrugated tube 3 internal flows and the cylinder body 1 and communicating with air, if cylinder body 1 inner fluid pressure changes, can make corrugated tube 3 do stretching motion, with moving displacement output, reach the purpose of demonstration by the pressure take-off lever 4 that is fixed in corrugated tube 3 upper ends.The displacement of pressure take-off lever 4 is directly proportional with corrugated tube 3 inside and outside pressure differences.The direction of arrow is fluid fluid passage in the utility model in the accompanying drawing.
The content that is not described in detail in this instructions belongs to this area professional and technical personnel's known prior art.
