Description
Technical field
The utility model is related to a kind of pressure sensor, more particularly to a kind of ceramic pressure sensor.
Background technology
Pressure sensor is the most commonly used a kind of sensor in industrial practice, and it is widely used in various industrial automatic control rings
Border, be related to water conservancy and hydropower, railway traffic, intelligent building, production automatic control, Aero-Space, military project, petrochemical industry, oil well, electric power, ship,
Numerous industries such as lathe, pipeline.The sealing of pressure sensor is a very important index, and the reliability of product sealing goes out
It is now abnormal, cause machine oil to leak, properties of product can be made to fail；And common pressure sensor does not have the structure of pressure release, no
Can the pressure release when pressure is excessive.
Utility model content
The utility model mainly solving the technical problems that provide a kind of anti-impact force strong, good airproof performance and can pressure release pottery
Porcelain pressure sensor.
In order to solve the above technical problems, the technical scheme that the utility model is used is：A kind of ceramic pressure sensor,
Including housing, pressure core, gland, cable and plug, ceramic pressure core body, gland and ceramic pressure core body are provided with housing
Abut, shell one end is provided with external thread column, pressure through hole is provided with external thread column, and pressure through hole is led at ceramic pressure core body,
External thread column is provided with pressure release through hole, and pressure release through hole is communicated with pressure through hole and is vertically arranged with pressure through hole.
Further, ceramic pressure core body connection cable, cable connector plug.
Further, ceramic pressure core body is projection shape, and the bottom of ceramic pressure core body is provided with the depression of cylindrical shape,
Pressure through hole leads to recess, and gland is connected on the step of the ceramic pressure core body of projection shape.
Further, the first sealing ring is provided between housing and ceramic pressure core body, between ceramic pressure core body and gland
It is provided with the second sealing ring.
Further, adhesive is provided between gland and cable, adhesive is epoxy resin.
Beneficial effect：The utility model uses ceramic pressure core body, and pressure release through hole is provided with housing, and is provided with multiple
Sealing structure, can the pressure release when pressure is excessive, also with stronger corrosion resistance and abrasion resistance, anti-impact force, anti-vibration
Power is strong, and stability is high, good airproof performance.
Brief description of the drawings
Fig. 1 is a kind of structural representation of ceramic pressure sensor of the utility model.
Specific embodiment
The utility model is described further below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of ceramic pressure sensor, including housing 1, pressure core 2, gland 3, cable 4 and plug
5, ceramic pressure core body 2 is provided with housing 1, gland 3 is abutted with ceramic pressure core body 2, the connection cable 4 of ceramic pressure core body 2, electricity
Cable 4 connects plug 5；The one end of housing 1 is provided with external thread column 11, and pressure through hole is provided with external thread column 11, and pressure through hole leads to pottery
At porcelain pressure core 2, external thread column 11 is provided with pressure release through hole 12, pressure release through hole 12 communicated with pressure through hole and with pressure through hole
Be vertically arranged, when ceramic pressure sensing core body 2 perceive pressure it is excessive when, can be let out by way of opening pressure release through hole 12
Pressure, prevents from causing to damage due to the excessive parts to the utility model or other structures of pressure；Ceramic pressure core body 2 is boss
Shape, the bottom of ceramic pressure core body 2 is provided with the depression of cylindrical shape, and pressure through hole leads to recess, and gland 3 is connected to boss
On the step of the ceramic pressure core body 2 of shape, can cause that gland 3 is fixed to ceramic pressure core body 2 using this structure
When pressure act on around ceramic pressure core body 2, will not to the position build-up of pressure of the sensed pressure of ceramic pressure core body 2 with
Cause inaccurate in pressure measurement；The first sealing ring 12, ceramic pressure core body 2 and gland 3 are provided between housing 1 and ceramic pressure core body 2
Between be provided with the second sealing ring 23, be provided with adhesive 34 between gland 3 and cable 4, adhesive 34 is epoxy resin, in this way, right
The sealing at these three positions has fully ensured that sealing of the present utility model.
When using, the utility model is fixed using the external thread column 11 of the one end of housing 1, plug 5 is inserted in accordingly
Side, when pressure is applied to the recess of ceramic pressure core body 2 by pressure through hole, ceramic pressure core body 2 can sense phase
The pressure answered, pressure data is transferred out by cable, if perceive pressure higher than normal value or excessive pressure, can be led to
The mode pressure release for opening pressure release through hole 12 is crossed, the pressure at tested place is reduced, in order to avoid to zero of the utility model or other structures
Part causes to damage.The utility model uses ceramic pressure core body 2, and pressure release through hole 12 is provided with housing 1, and is provided with multiple close
Seal structure, can the pressure release when pressure is excessive, also with stronger corrosion resistance and abrasion resistance, anti-impact force, anti-knock power
By force, stability is high, good airproof performance.
Implementation method of the present utility model is these are only, the scope of the claims of the present utility model, every profit is not thereby limited
The equivalent structure made with the utility model specification and accompanying drawing content, is directly or indirectly used in other related technology necks
Domain, similarly within scope of patent protection of the present utility model.
