Abstract
The utility model discloses a novel high-pressure ceramic seal structure, include: shell and ceramic assembly, the recess has been seted up to one side inner wall of shell, O type circle has been placed to shell surface recess, one side of O type circle is connected with ceramic assembly, one side of ceramic assembly is connected with the clamping ring, the one end opening part at the shell is installed to the clamping ring. This novel high-pressure ceramic seal structure places O type circle inside the recess on shell surface, later with ceramic package is smooth places in one side of O type circle, carries out the interference with the shell with the clamping ring again and is connected for the clamping ring is sealed with the shell junction, and rethread laser-beam welding machine welds the junction of clamping ring and shell, thereby assembles this seal assembly, and this seal assembly leakproofness is strong, avoids traditional equipment can take place the condition of revealing under high pressure.
Description
Technical Field
The utility model relates to a pottery pressure sensor technical field specifically is a novel high-pressure ceramic seal structure.
Background
The ceramic pressure sensor has no liquid transmission, pressure acts on the front surface of the ceramic diaphragm directly to make the diaphragm produce small deformation, the thick film resistor is printed on the back surface of the ceramic diaphragm to connect into a Wheatstone bridge, and the bridge produces a voltage signal which is in direct proportion to the pressure, highly linear and excitation voltage due to the piezoresistance effect of the piezoresistor, so as to measure the pressure.
This prior art solution also presents the following problems when in use:
1. traditional ceramic pressure sensor carries out the side seal to ceramic pressure sensor through the mode of side seal and handles, can take place the risk of revealing under the highly compressed condition, causes unexpected emergence.
Improvements are needed to address the above issues to meet market demands.
Disclosure of Invention
An object of the utility model is to provide a novel high-pressure ceramic seal structure to solve the problem that proposes in the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: a novel high pressure ceramic seal structure comprising: shell and ceramic assembly, the recess has been seted up to one side inner wall of shell, O type circle has been placed to shell surface recess, one side of O type circle is connected with ceramic assembly, one side of ceramic assembly is connected with the clamping ring, the one end opening part at the shell is installed to the clamping ring.
Preferably, the O-shaped ring is of a circular ring structure, and the O-shaped ring seals the joint of the shell and the ceramic assembly through the structure.
Preferably, one side surface of the O-shaped ring is tangent to one side surface of the ceramic component, and the O-shaped ring enables the ceramic component to be flatly placed on the inner wall of the shell through the structure.
Preferably, be interference fit between clamping ring and the shell and be welded the junction of clamping ring and clamping ring for welding, through above-mentioned structure, seal clamping ring and shell junction through interference fit and welding.
Compared with the prior art, the beneficial effects of the utility model are that: this novel high-pressure ceramic seal structure, this seal assembly assembles, and this seal assembly leakproofness is strong, avoids traditional equipment can take place the condition of revealing under the high pressure.
1. Inside placing O type circle in the recess on shell surface, later with the smooth one side of placing O type circle of ceramic assembly, carry out the interference with the clamping ring again and be connected with the shell for the clamping ring is sealed with the shell junction, and rethread laser-beam welding machine welds the junction of clamping ring and shell, thereby assembles this seal assembly, and this seal assembly leakproofness is strong, avoids traditional equipment can take place the condition of revealing under the high pressure.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution: a novel high pressure ceramic seal structure comprising: the sealing device comprises a shell 1 and a ceramic component 3, wherein a groove is formed in the inner wall of one side of the shell 1, an O-shaped ring 2 is placed in the groove in the surface of the shell 1, the ceramic component 3 is connected to one side of the O-shaped ring 2, a pressing ring 4 is connected to one side of the ceramic component 3, and the pressing ring 4 is installed at an opening at one end of the shell 1;
In conclusion: as shown in fig. 1-4, when the novel high-pressure ceramic sealing structure is used, firstly, the O-shaped ring 2 is placed in the groove on the surface of the shell 1, then, the ceramic component 3 is placed on one side of the O-shaped ring 2 smoothly, then, the compression ring 4 is in interference connection with the shell 1, the connection part of the compression ring 4 and the shell 1 is sealed, then, the connection part of the compression ring 4 and the shell 1 is welded through a laser welding machine, and therefore the sealing component is assembled.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
