Abstract
The utility model discloses a kind of acidity-basicity sensor, including：Sensor body (E), it has the glass electrode (1) for immersing solution to be measured, glass electrode is installed on the front end of glass tube (2), the rear end of glass tube is connected with the connector (3) of sensor body, and the connector of sensor body is connected to the signal wire for exporting measurement data；Glass tube is arranged with upper surface and is resisted against connector lower end and is used for the gasket seal (4) in gap between sealed glass tube and connector, and glass tube is arranged with the fluorine rubber ring (5) that gasket seal (4) is resisted against to connector lower end.The beneficial effects of the utility model are：Acidity-basicity sensor provided by the utility model uses the fluorine rubber ring with glass tube tight fit and gasket seal is resisted against gap between glass tube and connector, so as to play good obturation effect to the gap.
Description
Technical field
The utility model is related to sensor technical field, more particularly, to a kind of acidity-basicity sensor.
Background technology
It needs to be sealed between the glass tube of existing acidity-basicity sensor and sensor connector, to completely cut off inner and outer ring
Border, and the sealing structure between existing glass tube and sensor connector is complex, and sealing effect is bad.
Utility model content
The purpose of this utility model is exactly to solve the above-mentioned problems, to provide a kind of acidity-basicity sensor, sealing effect
It is good.
In order to solve the above technical problems, the embodiment of the utility model provides a kind of acidity-basicity sensor, including：
Sensor body (E) has the glass electrode (1) for immersing solution to be measured, and glass electrode is installed on the front end of glass tube (2),
The rear end of glass tube is connected with the connector (3) of sensor body, and the connector of sensor body, which is connected to, exports measurement data
Signal wire；Glass tube is arranged with upper surface and is resisted against connector lower end and is used for gap between sealed glass tube and connector
Gasket seal (4), glass tube is arranged with the fluorine rubber ring (5) that gasket seal (4) is resisted against to connector lower end.
Compared with prior art, acidity-basicity sensor provided by the utility model is using the fluorubber with glass tube tight fit
It encloses and gasket seal is resisted against gap between glass tube and connector, so as to play good obturation effect to the gap.
Further, gasket seal (4) is made of polytetrafluoroethylene (PTFE).
Further, gasket seal (4) is flat structure, and the upper surface of gasket seal is annular flat planar.
Further, gasket seal (4) is provided with the extension for extending to gap between sealed glass tube and connector.
Further, the annular body of extension and gasket seal is integrally formed.
Further, the glass tube is provided with the ring part positioned at fluorine rubber ring lower part, the ring part and fluorine rubber ring
Between be provided with elastic component.
Description of the drawings
Fig. 1 is acidity-basicity sensor schematic diagram.
Specific embodiment
In order to which the technical means, creative features, achievable purpose and effectiveness for realizing the utility model are easy to understand, under
In conjunction with specific embodiments, the utility model is expanded on further in face.
Embodiment：As shown in Figure 1, a kind of acidity-basicity sensor, including：Sensor body E, it is to be measured molten with immersing
The glass electrode 1 of liquid, glass electrode are installed on the front end of glass tube 2, the rear end of glass tube and 3 phase of connector of sensor body
Even, glass tube grafting is installed on connector or is installed on connector, the connection of sensor body by nipple
Head is connected to the signal wire for exporting measurement data, and said structure belongs to the known prior art, and not in this to go forth.
Continue to see Fig. 1, glass tube is arranged with upper surface and is resisted against connector lower end and is used for sealed glass tube with being connected
The gasket seal 4 in gap between head, such as gasket seal made of polytetrafluoroethylene (PTFE), glass tube, which is arranged with, supports gasket seal 4
It is against the fluorine rubber ring 5 of connector lower end.It can be seen that gap can be effective by gasket seal between glass tube and connector
Closing, so as to play good sealing effect, and the reason for gasket seal can not be subjected to displacement, is fluorine rubber ring and glass
Glass pipe is sleeved on glass tube exterior surface by tight fit relation, and has what is continued upward to keep gasket seal and institute against power
Do not depart between the gap to be sealed.
It is noted that since connector lower end is planar loop configuration, in consideration of it, gasket seal 4 is flat
Structure, and the upper surface of gasket seal is annular flat planar, can so play good face and be engaged.And it is to avoid sealing
Gasket rotates, and can connector lower face be arranged to wavy end face, and the lower face so as to allow connector is uneven,
Gasket seal uses wavy shaped configuration at this time, so as to make the corresponding protruding parts insertion connector lower face of gasket seal corresponding
Recess portion so can both play face contact closed structure, and can also avoid gasket seal that unnecessary rotation occurs.
In addition, gasket seal 4 can set the extension for extending to gap between sealed glass tube and connector, this extension
The width in portion is identical with the size in gap, so as to further improve obturation effect of the gasket seal for gap.And extension with
The annular body of gasket seal is integrally formed, and both convenient for assembling work, is also beneficial to the reduction of cost.
As an improvement the glass tube is provided with the ring part (not shown) positioned at fluorine rubber ring lower part, it is described
Elastic component is provided between ring part and fluorine rubber ring, can be upward by fluorine rubber ring by elastic component, so as to keep close
The airtight performance of gasket, and elastic component includes but are not limited to spring part, spring part surface can set anti-corrosion structure layer.
It will be understood by those skilled in the art that the respective embodiments described above are to realize the specific implementation of the utility model
Example, and in practical applications, can to it, various changes can be made in the form and details, without departing from the spirit of the utility model
And scope.
