Abstract
The utility model discloses a kind of instrument and analyze anti-corrosive sample-taking tracing composite pipes: sampling pipe and compensating cable, the instrument power cable with three arrangements in isosceles triangle, be provided with self-limiting heating cable between three sampling pipes, three sampling pipes and compensating cable, instrument power cable are enclosed with metal screen layer, heat-insulation layer, metallic diaphragm and restrictive coating outward successively; Metal screen layer is aluminium foil layer; Restrictive coating is for strengthening PE.The utility model adopts many sampling pipes to coordinate the structure of heating tape, its heat-insulating property, mechanical property and capability of electromagnetic shielding all reach requirement, different process conditions can be adapted to, gas sample is gathered when can be used for remote environment monitoring, electric-heating belt makes the gas not condensation in sampling pipe, remain on more than dew point, measuring accuracy is improved.
Description
technical field:
The utility model relates to electric heating clothing arts, particularly relates to a kind of instrument and analyzes anti-corrosive sample-taking tracing composite pipes.
background technology:
Anti-corrosive heat sampling composite tube is the vitals in environment monitoring system; it is aided with self-limiting heating cable by one group of corrosion resistant high performance resin conduit and compensation cable forms inner core; additional heat-insulation layer, finally applies and protects overcoat to be composited with flame-proof polyethylene (PE).The automatic temp limit function of self-limiting heating cable, can ensure to maintain certain temperature in sampling pipe, thus ensures that collected specimens is consistent with initial value, finally guarantees the collection sample gas that environment monitoring system is continuous, correct as far as possible.And for the instrument of some petroleum systems, there is no special anti-corrosive sample-taking tracing composite pipes structure, equally with common anti-corrosive heat sampling composite tube be made up of a few parts such as sampling pipe, heating tape, heat-insulation layer, overcoats, heat-insulating property, mechanical property and effectiveness do not reach requirement.
utility model content:
The purpose of this utility model is just to provide a kind of instrument and analyzes anti-corrosive sample-taking tracing composite pipes, its heat-insulating property, mechanical property and capability of electromagnetic shielding all reach requirement, different process conditions can be adapted to, gas sample is gathered when can be used for remote environment monitoring, electric-heating belt makes the gas not condensation in sampling pipe, remain on more than dew point, measuring accuracy is improved.
The technical solution adopted in the utility model is:
A kind of instrument analyzes anti-corrosive sample-taking tracing composite pipes: sampling pipe and compensating cable, the instrument power cable with three arrangements in isosceles triangle, be provided with self-limiting heating cable between three sampling pipes, three sampling pipes and compensating cable, instrument power cable are enclosed with metal screen layer, heat-insulation layer, metallic diaphragm and restrictive coating outward successively.
Described metal screen layer is aluminium foil layer.
Described restrictive coating is for strengthening PE.
Compared with prior art, the beneficial effects of the utility model are:
The utility model adopts many sampling pipes to coordinate the structure of heating tape, its heat-insulating property, mechanical property and capability of electromagnetic shielding all reach requirement, different process conditions can be adapted to, gas sample is gathered when can be used for remote environment monitoring, electric-heating belt makes the gas not condensation in sampling pipe, remain on more than dew point, measuring accuracy is improved.
accompanying drawing illustrates:
Accompanying drawing 1 is the utility model structural representation.
embodiment:
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail:
A kind of instrument analyzes anti-corrosive sample-taking tracing composite pipes: sampling pipe 1 and compensating cable 2, the instrument power cable 3 with three arrangements in isosceles triangle, be provided with self-limiting heating cable 4 between three sampling pipes 1, three sampling pipes and compensating cable, instrument power cable are enclosed with metal screen layer 5, heat-insulation layer 6, metallic diaphragm 7 and restrictive coating 8 outward successively; Metal screen layer 5 is aluminium foil layer; Restrictive coating 8 is for strengthening PE.
Above-described embodiment is only preferably embodiment of the present utility model, and in addition, the utility model can also have other implementations.It should be noted that, under the prerequisite not departing from the utility model design, any apparent improvement and modification all should fall within protection domain of the present utility model.
