Description
Technical field
The utility model relates to a kind of water-temperature water-level sensor, especially a kind of sensor that is used to detect water-temperature water-level in the solar water heater water tank.
Background technology
Water-temperature water-level sensor is arranged in the water tank of solar water heater; Be used to detect water temperature and the water level in the water tank; Its structure generally comprises water-temperature water-level sensing circuit, stainless steel sensor pipe, silica gel section and stainless steel sleeve pipe, and stainless steel sensor pipe spacer sleeve also is connected with circuit respectively in water-temperature water-level sensing circuit outside, and the silica gel section is connected between adjacent two stainless steel sensor pipes; Be full of silica gel in stainless steel sensor pipe inside; Silica gel and silica gel section are integrally formed, and the stainless steel sleeve pipe is located at the outside of stainless steel sensor pipe and silica gel section, and its top links to each other with the stainless steel sensor pipe of outermost side.In the use, because of sensor is immersed in the water tank for a long time, easy incrustation on the outer wall of stainless steel sensor pipe, thus have influence on the sensitivity and the serviceable life of sensor.In addition, because the tracerse point of water-temperature water-level sensing circuit is welded on the inwall of stainless steel sensor pipe, spot welding place is easy to by corrosion; Use is prone to long afterwards penetrate and leaks; Easy and the stainless steel spot welding place corrosion disconnection of circuit signal line, water level signal can't be responded to, thereby influences the normal use of sensor.
Summary of the invention
The utility model technical matters to be solved is to propose the water-temperature water-level sensor of a kind of good operating stability, highly sensitive, long service life.
For solving the problems of the technologies described above; A kind of water-temperature water-level sensor of the utility model comprises water-temperature water-level sensing circuit, electrically insulating silicone rubber section, stainless steel sensor pipe, electric silica gel section and stainless steel sleeve pipe; Said stainless steel sensor pipe is the water level induction electrode; Said electric silica gel section is coated on the outside and mutual conduction of said stainless steel sensor pipe; Said stainless steel sensor pipe box is located at said water-temperature water-level sensing circuit outside and is conducted with circuit; Said electrically insulating silicone rubber section is located between adjacent two said stainless steel sensor pipes and with the said stainless steel sensor seal of tube and is fixedly linked, and the outer wall of said electrically insulating silicone rubber section is provided with insulation support body, and said stainless steel sleeve pipe box is located at the outside of said stainless steel sensor pipe and said electrically insulating silicone rubber section supporter; Its top links to each other with the stainless steel sensor pipe conducting of outermost side, and the sidewall of said stainless steel sleeve pipe is provided with paddle hole.
Above-mentioned a kind of water-temperature water-level sensor, it also includes the copper pipe section, and said copper pipe section is fixed on the inwall and the mutual conduction of said stainless steel sensor pipe, and the lead of said water-temperature water-level sensing circuit links to each other with the inwall conducting of said copper pipe section.
Above-mentioned a kind of water-temperature water-level sensor, it also includes the support plug, and said support plug is located at the inside of said electrically insulating silicone rubber section and stainless steel sensor pipe, and said water-temperature water-level sensing circuit is located on the said support plug.
Above-mentioned a kind of water-temperature water-level sensor, with corresponding said electrically insulating silicone rubber section bottom, said stainless steel sleeve pipe bottom be the flange-like end, the outside of this end and a pad crimping are fixed together.
The utility model is owing to adopted technique scheme; After the outside socket electric silica gel section of stainless steel sensor pipe; The electric silica gel section also simultaneously as the part of water level induction electrode, had both made working sensor tie incrustation scale on the stainless steel sensor pipe long afterwards, and the electric silica gel section still can sense the water level situation; And the stainless steel sensor pipe that links to each other through conducting with it is delivered to operating circuit, guaranteed the sensitivity and the stability of working sensor.After the stainless steel sensor pipe liner copper pipe section, the lead of water-temperature water-level sensing circuit does not just link to each other with the spot welding of stainless steel sensor inside pipe wall, links to each other and change with the inwall conducting of copper pipe section.Like this, just there is not solder joint on the stainless steel sensor pipe, thereby is difficult for corrosion yet, prolonged the serviceable life of sensor.Support plug (like glass dimension rod or put the epoxy resin rod) and can let sensor inner core straight elevator, thereby further strengthen the reliability of its support.Flange-like is adopted in the silicon rubber section bottom of outboard end, can sensor upwards be inserted from the bottom of water tank, thereby make it become a kind of underneath type water-temperature water-level sensor.
