Description
Technical field
The utility model relates to a kind of quake-proof type temperature instrumentation, belongs to temperature survey field.
Background technology
Aspect the temperature detection of the equipment such as various blower fans, water pump and outlet conduit medium thereof, temperature instrument adopts the temperature instrumentations such as common thermometric thermal resistance or thermopair to carry out thermometric substantially at present.Temperature probe is positioned at the steel protection tube with medium contact, by wire, is connected to terminal box; For anti-conduction, after wire adopts porcelain tube protection, integral body is enclosed within steel protection tube, to resist the pressure of detected medium; Terminal box is steel or aluminum, and back panel wiring plate is porcelain, with insulation protection, and terminal block and tight rigid contact of terminal box; By installing and connecting apparatus, as connector, flange etc., fix with equipment or pipeline again, form integrated.Because blower fan, water pump are driven by motor, its configuration is generally undertaken by the using and the reserved or dual-purpose one is standby, and the straight length of its outlet conduit is very short, and equipment and outlet conduit thereof vibrate terribly.Even if temperature instrumentation and pipeline do not resonate, after work a period of time, steel protection tube, magnetic post collide mutually, and porcelain plate and junction box body in terminal box collide mutually, magnetic post, porcelain plate are shaken bad, are short-circuited; If resonated, can the outside protective pipe shake of temperature instrumentation is disconnected, damage instrument and gas leakage, leakage, form in " fountain "; I.e. impact is produced and may be hurted sb.'s feelings again; Do not change, gas leakage (liquid) is also wasted; Do not detect its temperature parameter, produce and lack again data, affect production operation.
Summary of the invention
The purpose of this utility model is: provide a kind of rational in infrastructure, safe and reliable, measure relatively accurate a kind of quake-proof type temperature instrumentation.
In order to overcome the defect existing in background technology, the technical scheme that the utility model provides is: a kind of quake-proof type temperature instrumentation, comprise temperature probe, steel protection tube, terminal box, and it is characterized in that:
1. insulation oxide, temperature probe, connection wire are combined in steel protection tube, form steel protection tube combination unit;
2. the wiring porcelain plate in terminal box is connected with terminal box shell floor by the connecting rod with spring in the vertical direction, and seat is in " O " type insulator in the horizontal direction.
Described temperature probe is common temperature instrumentation element, utilizes existing national standard, as standard thermometric components and parts such as Pt100, Pt1000, thermopairs, is applicable to the temperature detection area requirement of measured medium; Be installed in steel protection tube combination unit.
Described shatter-proof shaped steel protection tube combination unit, in a kind of soft heatproof insulation tube, guarantees that it can expand with heat and contract with cold and insulate by the connection wire sleeve that connects temperature instrumentation sensor; Steel protection tube adopts pyramidal structure, makes it resistance to compression anti-disconnected; Between the insulation tube of guardwire and steel protection tube, fill the insulative oxide material of heatproof, reach sensor, connect between the insulation tube of wire and steel protection tube and be software and there is certain elasticity, make it not have very stiff and demanding space, reach shock-proof effect.
Described shatter-proof terminal box, select small-sized wiring porcelain plate, at peripheral one " O " type insulator of making of porcelain plate, there is elasticity, and be annulus cone, between porcelain plate and junction box body, utilize soft annulus cone to absorb the energy of operation vibration, there is not very stiff and demanding collision, effectively protect porcelain terminal block; Between the lower end and junction box body of terminal block, make a kind of Flexible Connector as spring, utilize this Flexible Connector to absorb the energy of operation vibration, there is not very stiff and demanding collision yet, effectively protect terminal block.
The utility model has solved the defect existing in background technology.Have rational in infrastructurely, safe and reliable, can be applicable to lower temperature (≤150 ℃) medium, measure the advantages such as relatively accurate, be improvement and the innovation that vibrating conduit or device temperature are detected.

Embodiment
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail.Shown in accompanying drawing be the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only shows the formation relevant with the utility model.Take common thermometric Pt100 standard thermometric components and parts, three-wire system carries out brief description as example.
Fig. 1 is shatter-proof temperature instrumentation one-piece construction schematic diagram.Fig. 2, Fig. 3 are respectively the section schematic top plan view of terminal box, protection tube.Terminal box (1), coupling arrangement (2), protection tube combination unit (4), consist of, terminal box (1) forms shatter-proof temperature instrumentation with protection tube combination unit (4) by screw thread or connected mode; Protection tube combination unit (4) includes thermometric components and parts and insulation oxide material (17), and (3) are erecting devices, and it is welded on process pipe or equipment; By coupling arrangement (2) and erecting device (3), fixedly temperature instrumentation is installed.
Terminal box is comprised of shell (13), terminal block (11), external wire barrel (12).(5) be binding post, (7) be gib screw, (6) be " O " type insulation annulus cone (as electro-insulating rubber etc.), (9) be arch brace body, be inserted in " O " type insulation annulus cone (6), (8) be spring, (10) be the wiring passage preformed hole that connects thermometric components and parts (14), (11) are porcelain terminal blocks.Between terminal block (11) and shell (13), design an insulation annulus cone (6), absorbing vibrational energy, guarantees that horizontal direction hard collision does not occur and damages terminal block (11); Between terminal block (11) lower surface and shell (13), design a spring (8), absorbing vibrational energy, guarantees that vertical direction hard collision does not occur and damages terminal block (11); By screw (7) link plate (11), the connection wire (15) of temperature probe (14) is connected to binding post (5) by preformed hole (10), then is connected to corresponding display unit by external spool (12).Make terminal box (1) reach whole three-dimensional shock-proof effect.
(14) be thermometric components and parts, (15) are the wires that is flexible coupling of having insulation sheath, and (16) are the conical steel pipes of coaxial Different Diameter, and (17) are insulation oxide materials; They are combined into one, and form shatter-proof shaped steel protection tube combination unit.Vibrate at work, owing to filling insulation oxide material (17) between thermometric components and parts (14), the wire that is flexible coupling (15) and conical steel pipe (16), hard collision does not occur, effectively protect temperature probe (14) and the wire that is flexible coupling (15); Owing to connecting wire (15), be soft, can do longlyer, even if expand with heat and contract with cold, also can not rupture; When tracer liquid or gas medium, because protection tube (16) is taper, can effectively reduce the impact area of media flow, reduce the probability of resonance.
