Abstract
The utility model discloses a kind of integrated high pressure pressure sensor elastomers, it is characterized by: the integrated high pressure pressure sensor elastomer is the Elastic Cylindrical body manufactured by metal material, upper end is elastic surface, and lower end is pressure-inducing nozzle, and centre is the impulse chamber for introducing pressure；The pressure-inducing nozzle periphery is machined with the external screw thread for being fixedly connected；The elastic surface lower part is machined with stress relief grooves；The pressure-inducing nozzle top, stress relief grooves lower part are machined with support edge.Strain resistor can be manufactured on the elastic surface and forms detection circuit, and when pressure acts on elastic surface by impulse chamber introducing, the detection circuit exports electric signal corresponding with pressure.Not the problem of due to sensitive core body and pressure-inducing nozzle unitary design, the two does not need to weld, and overcomes the not prison welding caused by the reasons such as welding equipment, technique due to leaks, be not capable of measuring big pressure, excess pressure.
Description
Technical field
The utility model relates to a kind of pressure sensor elastomer more particularly to a kind of one of hyperpressure easy to accomplish
Formula high-pressure pressure sensor elastomer.
Background technique
Sputtered thin film pressure transducer is a kind of pressure sensor of function admirable, it has, and precision is high, stability it is good with
And measuring medium temperature it is high the advantages that, in many such as Aeronautics and Astronautics, military project, nuclear industry, petrochemical industry, traffic, metallurgy, food, medicine
Field is applied.
But the sensitive core body and pressure-inducing nozzle of sputtered thin film pressure transducer be it is split type, need to weld after respectively processing
It is rising, due to welding equipment, technique etc., often when manufacturing wide range pressure sensor, commissure is easy to appear leakage,
If manufacture the super large range pressure sensor of 200MPa or more, it is more difficult to realize by welding.
Therefore, it is of crucial importance to develop a kind of integrated high pressure pressure sensor elastomer for not needing welding.
Summary of the invention
The purpose of this utility model is to provide a kind of integrated high pressure pressure sensor elastomer for not needing welding, needles
To the deficiencies in the prior art, high pressure, the production problem of hyperpressure sensor are realized.
In order to solve the above technical problems, the technical solution of the utility model is: a kind of integrated high pressure pressure sensor bullet
Property body, it is characterised in that: the integrated high pressure pressure sensor elastomer be by metal material manufacture Elastic Cylindrical body,
Upper end is elastic surface, and lower end is pressure-inducing nozzle, and centre is the impulse chamber for introducing pressure；The pressure-inducing nozzle periphery, which is machined with, to be used for
The external screw thread being fixedly connected；The elastic surface lower part is machined with stress relief grooves；The pressure-inducing nozzle top, stress relief grooves lower part
It is machined with support edge.
Strain resistor can be manufactured on the elastic surface and forms detection circuit, when pressure is acted on by impulse chamber introducing
When elastic surface, the detection circuit exports electric signal corresponding with pressure.
Compared with prior art, having the beneficial effect that possessed by the utility model is not influencing any performance of elastomer
Under the premise of, conventional split type sensitive core body and pressure-inducing nozzle design is integrated, and the two does not need to weld, and overcomes because of welding
Not prison welding caused by the reasons such as equipment, technique, the problem of not being capable of measuring big pressure, excess pressure.
Detailed description of the invention
Fig. 1 is the diagrammatic cross-section of the integrated high pressure pressure sensor elastomer of the utility model.
In figure: 1, elastic surface, 2, pressure-inducing nozzle, 3, impulse chamber, 4, support edge, 5, stress relief grooves, 6, external screw thread
Specific embodiment
As shown in Figure 1, a kind of integrated high pressure pressure sensor elastomer, the cylindrical integral type manufactured by metal material
Elastomer, upper end are elastic surface 1, and lower end is pressure-inducing nozzle 2, and centre manufacture has the impulse chamber 3 for introducing pressure.The pressure-inducing nozzle
2 peripheries are machined with the external screw thread 6 for being fixedly connected, and 1 lower part of elastic surface is machined with stress relief grooves 5；The pressure-inducing nozzle 2
Top, 5 lower part of stress relief grooves are machined with the support for being used to support shell or six square nuts along 4.
Strain resistor can be manufactured on the elastic surface 1 and forms detection circuit, when pressure is acted on by 3 introducing of impulse chamber
When elastic surface 1, the detection circuit exports electric signal corresponding with pressure.
Due to sensitive core body and pressure-inducing nozzle unitary design, the two does not need to weld, and overcomes because of welding equipment, technique etc.
Not prison welding caused by reason and the problem of leak, be not capable of measuring big pressure, excess pressure.
The above is only the better embodiment of the utility model, is not construed as the limit to the scope of the utility model
System, and the scope of the claims that the utility model is advocated is not limited thereto, all personages for being familiar with this field skill, according to
Technology contents disclosed by the utility model, can think easily and equivalence changes, the protection scope of the utility model should all be fallen into
It is interior.
