Description
Technical field
The utility model relates to pressure sensor technique fields, and in particular to be used to delay in a kind of pressure transmitter impulse mouth
Double damping structures of stamping press impact.
Background technique
Pressure transmitter is a kind of equipment for converting pressure into pneumatic signal or electromotive signal carries out control and teletransmission, it
The physical pressures parameters such as gas, liquid that load cell is experienced can be transformed into standard electric signal (such as 4 ~
20mADC etc.), it measured, indicated and procedure regulation with supplying the secondary meters such as indicator alarm, recorder, adjuster.Pressure
Power transmitter is a kind of sensor the most commonly used in industrial practice, is widely used in various industrial automatic control environment, is related to water conservancy
Water power, railway traffic, intelligent building, production automatic control, aerospace, military project, petrochemical industry, oil well, electric power, ship, lathe, pipeline etc.
Numerous industries.Wherein to spread silicon core as its measurement performance with higher of the pressure transmitter of pressure core is surveyed, that is, measure
Sensitivity and precision are high, measurement accuracy up to 0.1FS, therefore its in the use using liquid, gas, steam as medium compared with
It is extensive, for example the oil pressure of the hydraulic system of pressure precision demanding oil pressure machinery, injection molding machine, die casting machine etc. is measured；By
It is not allow for greater impact in the induction side of diffusion silicon core, otherwise in addition to the linearity of core may be destroyed, may be used also
The permanent failure of diffusion silicon core can be will cause, it is therefore desirable to slow down medium to be measured to greatest extent to diffusion silicon core
Compression shock；But traditional pressure transmitter is substantially using 3 millimeters of straight-through tracting pressuring holes and carries out pressure measurement, later
There is the tracting pressuring hole of 0.2 mm dia on the market to reduce compression shock, but pressurizes moment in medium in actual use
Or the impact force of diffusion silicon core induction side is acted on when quick washing due to not by multi-buffer, hydraulic pressure system
System work pressure often reaches MPA up to a hundred, so even if reducing aperture but still larger to the impact force of diffusion silicon, it is long this with
Measurement accuracy decline that is past and causing diffusion silicon core, and the service life of diffusion silicon core, that is, influence pressure transmitter
Service precision and service life.

The both ends of Buddhist nun's structure are respectively provided with the first plug and the second plug, and it is stifled to first pass through second when pressure quick washing when in use
Then head enters back into subsequent tracting pressuring hole inner cavity, so that first order buffering is formed, this is because the internal diameter of tracting pressuring hole is compared with plug
The diameter of bore of 0.2MM is big, therefore fills tracting pressuring hole inner cavity and need the time to complete, next again by passing to after the first plug
The induction side for spreading silicon leads to again after complementing each other to form primary buffering by the second plug and tracting pressuring hole inner cavity due to pressure
It crosses and just forms second of pressure buffer after the first plug, therefore the last pressure for reaching diffusion silicon induction side further subtracts
It is few, i.e., significantly more efficient protection is formed to diffusion silicon core.
Preferably, second plug is fixed with the second connecting column by threads, and the end of the second plug is set
It is equipped with interior hexagonal groove, facilitates the fixation of the second plug and the second connecting column.
Preferably, being additionally provided with groove on the inner wall of the accommodating cavity, sealing ring, institute are additionally provided in the accommodating cavity
It states sealing ring to be fixed in groove, the sealing ring is viton seal ring, and fluorubber has good oil resistant, property resistant to high temperature
Can, help to form excellent sealing between the first connecting column and diffusion silicon core, avoids leakage.
Preferably, the fastener head consolidates hexagon setting, facilitate the tightening operation of double damping structures.
The utility model has the following beneficial effects: due to being respectively provided with the first plug and second at the both ends of double damping structures
Plug first passes through the second plug when pressure quick washing when in use, subsequent tracting pressuring hole inner cavity is then entered back into, thus shape
It is buffered at the first order, this is because the internal diameter of tracting pressuring hole is big compared with the diameter of bore of the 0.2MM of plug, therefore fills tracting pressuring hole inner cavity
The time is needed to complete, next again by passing to the induction side of diffusion silicon after the first plug, since pressure passes through the second plug
It is slow again by second of pressure is just formd after the first plug after complementing each other to form primary buffering with tracting pressuring hole inner cavity
Punching, therefore the last pressure for reaching diffusion silicon induction side further reduces, i.e., is formed to diffusion silicon core significantly more efficient
Protection, therefore the service precision of pressure transmitter has been effectively ensured, while also extending the use longevity of pressure transmitter therefrom
Life.
