Technical field
The utility model relates to a kind of explosion-proof type temperature controller.
Background technology
At present, the type field temperature controller that is used for requirement of explosion proof occasions such as oil, chemical industry, combustion gas, mine mainly is made up of box body and temperature detect switch (TDS), wherein, the thermometric assembly of temperature detect switch (TDS) is formed by connecting by kapillary and temperature probe, and kapillary and temperature probe all place the box body outside, be exposed in the environment for use, often be subjected to mechanical collision and cause damage, perhaps, owing to the corrosion in the environment for use causes damage, the serviceable life of temperature controller is short, and what influence was produced carries out smoothly.High-temperature liquid state epoxy resin often takes place and leaks into the inner phenomenon of switch in the totally-enclosed process of pouring epoxy resin in temperature detect switch (TDS), and switch is scrapped.
The utility model content
The utility model is in order to overcome weak point of the prior art, to provide a kind of and can strengthen the protection to the thermometric assembly satisfying under the condition of requirement of explosion proof, improving the explosion-proof type temperature controller in serviceable life.
The utility model is achieved through the following technical solutions:
A kind of explosion-proof type temperature controller; comprise box body; temperature detect switch (TDS); described box body is formed by connecting by screw at the bottom of by lid and box; the junction is provided with O-ring seal at the bottom of described lid and the box; on described temperature detect switch (TDS) is installed at the bottom of the box; described temperature detect switch (TDS) is made up of control section and thermometric assembly; the capillary type thermometric assembly of described thermometric assembly for being formed by connecting by kapillary and temperature probe; it is characterized in that; described kapillary twines and is placed on box body inside; described temperature probe places in the stainless steel protection sleeve pipe of lower end closed; the upper end of described stainless steel protection sleeve pipe by screw thread and cushion rubber and box at the bottom of between be tightly connected; be provided with aluminium foil or Copper Foil heat conduction layer between described stainless steel protection sleeve pipe and the described temperature probe; described temperature detect switch (TDS) is regulated the following control section of temperature button and is embedded in the epoxy resin embedding layer; temperature detect switch (TDS) 220V node control signal wire passes epoxy resin embedding layer; and the power supply by the box body side advances wire hole output; the root of temperature detect switch (TDS) regulating shaft is equipped with rubber sealing boot, scribbles electric insulating sealant at the place, slit of temperature detect switch (TDS) body.
Described lid is provided with seal groove, and described O-ring seal embeds in the seal groove.
The utlity model has following technique effect:
Explosion-proof type temperature controller of the present utility model, the root of temperature detect switch (TDS) regulating shaft is equipped with rubber sealing boot, scribbles electric insulating sealant at the place, slit of temperature detect switch (TDS) body, makes the success ratio of pouring epoxy resin can reach 100%.The winding of kapillary in the thermometric assembly is placed on box body inside; temperature probe places the outside also protected sleeve pipe of box body to encase; can prevent exterior mechanical collision and corrosion damage, in the serviceable life of improving temperature controller, ensure carrying out smoothly of producing the thermometric assembly.

Fig. 2 is the cut-open view of the utility model explosion-proof type temperature controller.
Embodiment
Below in conjunction with specific embodiment the utility model is described in detail.
The synoptic diagram of the utility model explosion-proof type temperature controller comprises box body, temperature detect switch (TDS) as depicted in figs. 1 and 2, and described box body 1 is formed by connecting by screw at the bottom of by lid 2 and box, and lid 2 is provided with O-ring seal 10 with 1 junction at the bottom of the box.On described temperature detect switch (TDS) is installed at the bottom of the box.Described temperature detect switch (TDS) is made up of control section and thermometric assembly; the capillary type thermometric assembly of described thermometric assembly for being formed by connecting by kapillary 7 and temperature probe 4; kapillary 7 twines and is placed on box body inside; temperature probe 4 places the box body outside; temperature probe 4 outsides are surrounded by the stainless steel protection sleeve pipe 6 of lower end closed; the upper end of stainless steel protection sleeve pipe 6 is tightly connected between 1 at the bottom of by screw thread and packing washer and box; be provided with aluminium foil or Copper Foil heat conduction layer 5 between stainless steel protection sleeve pipe 6 and the temperature probe 4, prolonged the serviceable life of switch.
The control section 3 of described temperature detect switch (TDS) adjusting knob below 8 is embedded in the epoxy resin embedding layer 11.
Temperature detect switch (TDS) 220V node control signal wire 9 passes epoxy resin embedding layer 11, and advances wire hole output by the power supply of box body side.The root of temperature detect switch (TDS) regulating shaft is equipped with rubber sealing boot, scribbles electric insulating sealant at the place, slit of temperature detect switch (TDS) body.Its method for making is: with common temperature detect switch (TDS) the pouring epoxy resin totally-enclosed before, with the root sealing of rubber sealing boot with the temperature detect switch (TDS) regulating shaft, with electric insulating sealant all slits of temperature detect switch (TDS) body are smeared, sealing, water epoxy resin then, after drying, the temperature detect switch (TDS) regulating shaft can rotate freely, guarantee the temperature detect switch (TDS) cleaning inside, node safety.
In order to reach best sealing effectiveness, lid 2 is provided with seal groove, and described O-ring seal 10 embeds in the seal groove, satisfies the safety of using in explosive atmosphere.
Because temperature probe places the box body outside and is encased by the stainless steel protection sleeve pipe, can prevent exterior mechanical collision and the corrosion damage to the thermometric assembly, in the serviceable life of improving temperature controller, ensures carrying out smoothly of production.
