Abstract
The utility model proposes a kind of new diffusion silicon formula differential capsules, it is related to differential pressure transmitter technical field, including bellows, gland and diffusion silicon differential pressure pick-up, cavity is formed in the bellows, groove is equipped in the cavity, the diffusion silicon differential pressure pick-up is mounted in the groove, and the diffusion silicon differential pressure pick-up is fitted close with the groove.The modular bellows design of the utility model, diffusion silicon differential pressure pick-up is individually placed in bellows, sealing effect is played by sealing ring, entire bellows inner chamber body design can be longer 1mm than diffusion silicon differential pressure pick-up, outside will not impact diffusion silicon differential pressure pick-up when compressing bellows, improve the stability of product, use modularized design, it is easy to later maintenance, repair, even upgrades, reduces production and use cost.
Description
Technical field
The utility model is related to differential pressure transmitter technical field, especially a kind of new diffusion silicon formula differential capsule.
Background technology
Sensor is encapsulated in bellows by existing diffusion silicon formula differential capsule using welding procedure.Because internal member
Part is welded with diaphragm capsule housing, causes stress, and the zero stability for causing entire bellows is poor, furthermore because can be pressed from both sides when installing bellows
Tight bellows, clamping when, can equally make internal element generate stress, cause instrument unstable.
Utility model content
The utility model provides a kind of new diffusion silicon formula differential capsule, and core will not be impacted, improve product
Stability.
The utility model specifically adopts the following technical scheme that realization：
A kind of new diffusion silicon formula differential capsule including bellows, gland and spreads silicon differential pressure pick-up, shape in the bellows
Into there is cavity, groove is equipped in the cavity, the diffusion silicon differential pressure pick-up is mounted in the groove, and the diffusion silicon is poor
Pressure sensor is fitted close with the groove.
Preferably, the length of the cavity is longer 1mm than the diffusion silicon differential pressure pick-up length.
Preferably, the gland is equipped with ring groove, sealing ring is mounted in the ring groove.
New diffusion silicon formula differential capsule provided by the utility model, its advantage are：Modular bellows design,
Diffusion silicon differential pressure pick-up is individually placed in bellows, plays sealing effect by sealing ring, entire bellows cavity design can be than expanding
The silicon long 1mm of differential pressure pick-up is dissipated, diffusion silicon differential pressure pick-up will not be impacted when outside compresses bellows, improve the steady of product
It is qualitative, using modularized design, it is easy to later maintenance, repair, even upgrades, reduces production and use cost.
Description of the drawings
Fig. 1 is the front view of the utility model diffusion silicon formula differential capsule；
Fig. 2 is the right view of the utility model diffusion silicon formula differential capsule；
Fig. 3 is exploded view of the utility model diffusion silicon formula differential capsule with spreading silicon differential pressure pick-up.
Specific embodiment
To further illustrate each embodiment, the utility model is provided with attached drawing.These attached drawings is in the utility model exposure
A part for appearance mainly to illustrate embodiment, and can coordinate the associated description of specification to explain the running of embodiment original
Reason.With reference to these contents, those of ordinary skill in the art will be understood that other possible embodiments and this practicality are new for cooperation
The advantages of type.Component in figure is not necessarily to scale, and similar element numbers are conventionally used to indicate similar component.
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
As shown in Figs. 1-3, a kind of new diffusion silicon formula differential capsule provided in this embodiment, including bellows 1, gland 2 and
Silicon differential pressure pick-up 3 is spread, cavity is formed in bellows 1, groove 11 is equipped in cavity, diffusion silicon differential pressure pick-up 3 is mounted on
In groove 11, diffusion silicon differential pressure pick-up 3 is fitted close with groove 11, and gland 2 can be with cavity precision-fit.The wherein length of cavity
Degree is longer 1mm than diffusion silicon differential pressure pick-up length, and ring groove 21 is equipped on gland 2, and sealing ring is mounted on ring groove 21
It is interior, it can ensure that intracavitary sensor 3 is fitted closely with cavity inner wall after covering gland 2.
New diffusion silicon formula differential capsule provided by the utility model using modular bellows design, spreads silicon differential pressure
Sensor is individually placed in bellows, plays sealing effect by sealing ring, entire bellows cavity design can be passed than diffusion silicon differential pressure
Sensor long 1mm will not impact diffusion silicon differential pressure pick-up when outside compresses bellows, improve the stability of product, use
Modularized design is easy to later maintenance, repair, even upgrades, and reduces production and use cost.
Although specifically showing and describing the utility model with reference to preferred embodiment, those skilled in the art should
This is understood, in the spirit and scope for not departing from the utility model that the appended claims are limited, in form and details
On the utility model can be made a variety of changes, be the scope of protection of the utility model.
