Description
Technical field
This utility model belongs to field of electronic devices, relates in particular to a kind of shatter-proof pressure transducer of high pressure.
Background technology
Pressure transducer is a kind of sensor the most commonly used in industrial practice, it is widely used in various industry automatic control environment, relates to numerous industries such as water conservancy and hydropower, railway traffic, intelligent building, production automatic control, Aero-Space, military project, petrochemical industry, oil well, electric power, boats and ships, lathe, pipeline.Existing high-pressure pressure sensor is directly connected on water pipe body to be detected, and during detection, the vibrations of body can be transmitted on sensor, causes the Detection results of sensor to be affected.How overcoming an above-mentioned difficult problem is the direction that those skilled in the art need research.
Utility model content
For overcoming the problems referred to above, this utility model provides a kind of shatter-proof pressure transducer of high pressure.
Its concrete technical scheme used is as follows:
A kind of shatter-proof pressure transducer of high pressure, including structural connection, pressure transducer, hold-down ring, edge face sealing member, pressure guiding pipe, bleed valve and mounting bracket.Described structural connection is provided with a cavity, and this cavity is provided with liquid inlet, liquid outlet and the incoming line being conducted to outside structural connection；The sensing head of pressure transducer is pressed in the cavity of structural connection by described hold-down ring, and described pressure guiding pipe and bleed valve are individually fixed at liquid inlet and the liquid outlet of structural connection cavity；Described edge face sealing member is fixed on structural connection, realizes the end face high-pressure-resistant sealed of the liquid inlet to cavity and liquid outlet by mounting flange；Described mounting bracket fixes with edge face sealing member.
Use this technical scheme: use end face seal structure at the liquid inlet of cavity and liquid outlet, promote the integral high pressure sealing property of sensor；Mounting bracket is utilized to be fixed on body of wall by shatter-proof for whole high pressure pressure transducer, and the highly pressurised liquid in body to be detected is drained on structural connection by pressure guiding pipe, the liquid inlet of cavity enters and derived by bleed valve through liquid outlet, utilization arranges pressure guiding pipe and has pulled open the distance of body to be detected and the shatter-proof pressure transducer of high pressure, prevents the vibrations of body to be detected self to be transmitted on the shatter-proof pressure transducer of high pressure thus affects sensing detection result.
Preferably, in above-mentioned high pressure is shatter-proof pressure transducer: the cavity on described structural connection is in the font of falling T, and described liquid inlet and liquid outlet are all horizontally placed on the waist of structural connection, and described incoming line is arranged at the top of structural connection.
Compared with prior art, this utility model leaves by making sensor and on-the-spot pressure tap vibroseis be separated by, it is achieved shatter-proof effect.There is good high voltage performance and earthquake-proof function, improve the degree of accuracy of detection, reduce cost.
Accompanying drawing explanation

Fig. 2 is the structural representation of structural connection, pressure transducer, hold-down ring in Fig. 1.
In above-mentioned accompanying drawing, each parts are as follows with the corresponding relation of reference:
1, structural connection；2, pressure transducer；3, hold-down ring；4, edge face sealing member；5, pressure guiding pipe；6, bleed valve；7, mounting bracket.
Detailed description of the invention
In order to be illustrated more clearly that the technical solution of the utility model, below in conjunction with accompanying drawing, this utility model is further described.
Embodiment 1 the most of the present utility model:
A kind of shatter-proof pressure transducer of high pressure, including structural connection 1, pressure transducer 2, hold-down ring 3, edge face sealing member 4, pressure guiding pipe 5, bleed valve 6 and mounting bracket 7；Described structural connection 1 is provided with a cavity, and this cavity is provided with liquid inlet, liquid outlet and the incoming line being conducted to outside structural connection 1；Cavity on described structural connection 1 is in the font of falling T, and described liquid inlet and liquid outlet are horizontally placed on the waist of structural connection 1, and described incoming line is arranged at the top of structural connection 1.The sensing head of pressure transducer 2 is stretched in cavity by incoming line, and the sensing head of pressure transducer 2 is pressed in this cavity by described hold-down ring 3.Described pressure guiding pipe 5 and bleed valve 6 are individually fixed at liquid inlet and the liquid outlet of structural connection 1 cavity；Described edge face sealing member 4 is fixed on structural connection 1, realizes the end face high-pressure-resistant sealed of the liquid inlet to cavity and liquid outlet by mounting flange；Described mounting bracket 7 fixes with edge face sealing member 4.
In practice, its work process is as follows:
Staff first passes through mounting bracket 7 and is fixed on body of wall by shatter-proof for whole high pressure pressure transducer, and pressure guiding pipe 5 is connected to by body to be detected, highly pressurised liquid in body to be detected by pressure guiding pipe 5 flow to structural connection 1, flowed in cavity by the cavity liquid inlet on structural connection 1, the sensing head of pressure transducer 2 highly pressurised liquid to flowing through carries out pressure detecting, highly pressurised liquid is derived in cavity by bleed valve 6 through liquid outlet subsequently.During the distance of body to be detected and structural connection 1 be equivalent to the length of pressure guiding pipe 6, the vibrations that effectively prevent body to be detected self are transmitted on the shatter-proof pressure transducer of high pressure thus affect sensing detection result.Use end face seal structure at the liquid inlet of cavity and liquid outlet, promote the integral high pressure sealing property of sensor.
The above; it is only specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; any those skilled in the art is in technical scope disclosed in this utility model; the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with the protection domain of claims.
