Description of the drawings
Fig. 1 is the structural schematic diagram of the electrode in high pressure lining flow meter electrode structure provided by the utility model；
Fig. 2 is the structural schematic diagram of high pressure lining flow meter electrode structure provided by the utility model.
Wherein, 1, electrode, 2, electrode pressure cap, 3, insulation sleeve, 4, electrode tip holder, 5, pipe, 6, lining, 7, pressure ring.
Specific implementation mode
The utility model is described in further detail with reference to specific embodiment, described is to the utility model
Explanation rather than limit.
Referring to Fig. 1 to Fig. 2, a kind of high pressure lining flow meter electrode structure, including pipe 5；The inner wall of pipe 5 is attached with lining 6,
Pressure ring 7 connect with pipe 5 and compresses lining 6, and electrode tip holder 4 is equipped on pipe 5, and electrode 1, electrode pressure cap 2 and electricity are enclosed on lining 6
Electrode seat 4 connects, and electrode pressure cap 2 compresses electrode by insulation sleeve 3, and insulation sleeve 3 is connect with electrode 1.
The flat segments of 1 front end of electrode are designed with the taper gradient, are additionally provided with annular groove on electrode 1, on annular groove
Face is equipped with dome.
The lining is made of plastic material.
Specifically, being attached with lining 6 on 5 inner wall of pipe, pressure ring 7 connect with pipe 5 and compresses lining 6, and electrode tip holder 4 is mounted on pipe
On 5, electrode 1 is wrapped up by lining 6, and insulation sleeve 3 connect the purpose for playing and insulating with electrode pressure cap, electrode pressure cap 2 and electricity with electrode 1
The connection of electrode seat 4 compresses electrode 1 by insulation sleeve 3.To formed the structure that is combined with lining of an electrode combined with form it is close
Seal structure.
The electrode structure is mainly characterized by：The flat segments of electrode front end take taper slope design, and electrode installs
More crush seal face combination is compacter afterwards, and sealing effect is better；Next devises annular groove, and the moulding material of lining is all filled out
It fills in annular groove groove and is equivalent to and increase one of ring type seal (i.e. "O"-ring), electrode retaining collar here
When top stress is pressed down against, plasticity filling lining is extruded to form endless belt sealing, taper dome above shape groove slot
Inclined-plane is pressed down against plastic liner and forms inclined-plane sealing, is at this moment deformed into ring packing and seals double sealing effect with inclined-plane, whole
The sealing of body electrode reaches sealing using itself plastic deformation of lining, and sealing effect is made to be substantially improved, and improves electrode and modeling
The pressure-resistant upper limit for combining closely to improve lining class electrode completely of property lining.
The pressure resistance of high pressure lining flowmeter is allowed to rise to a new stage；
High pressure lining flow meter electrode structure provided by the utility model, the structure type of the electrode are combined close with lining
Envelope mode, by test, pressure resistance reaches as high as 60Mpa far beyond the pressure-bearing limit of present lining class flowmeter,
Therefore the pressure-bearing voltage endurance capability for substantially increasing lining class flowmeter, has reached new level.
The above application for illustrating the sealing structure for being the electrode, only limit are typical for example, being not limited to be suitable only for this
The application scenario of such electrode of case.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
