Abstract
The utility model discloses a water-temperature water-level sensor which comprises a water-temperature water-level sensing circuit, a stainless steel induction tube, a silica gel section, and a stainless steel sleeve; the stainless steel induction tube is sleeved outside the water-temperature water-level sensing circuit at intervals and is connected with the circuit, the silica gel section is arranged between two adjacent stainless steel induction tubes, the two ends of the silica gel section are closely connected with the stainless steel induction tube, the stainless steel induction tube is full of silica gel inside, the silica gel and the silica gel section are formed into an integer. As the silica gel has no poison, has better corrosion resistance, has less expansion-shrinkage ratio from high temperature to low temperature, has good age resistance performance and good antioxidation performance, and also has good flexibility, the operation stability of the sensor can be ensured, and the service life of the sensor is prolonged.
Description
Technical field
The utility model relates to a kind of water-temperature water-level sensor, especially a kind of water-temperature water-level 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 water level in the water tank, its structure generally comprises water-temperature water-level sensing circuit, stainless steel sensor pipe, heat-shrink tube and stainless steel sleeve pipe, stainless steel sensor pipe spacer sleeve is connected in water-temperature water-level sensing circuit outside and with circuit, heat-shrink tube is connected between adjacent two stainless steel sensor pipes, the stainless steel sleeve pipe is located at the outside of stainless steel sensor pipe and heat-shrink tube, and its top links to each other with the stainless steel sensor pipe of outermost side.Because heat-shrink tube is made (metal tube of the employing inside that has and outside thin-walled rubber tube fit) by rubber, and the water-temperature water-level sensor long period of soaking is in water tank, be subjected to the influence of factors such as water temperature just changes in the water tank, the variation of water quality Acidity of Aikalinity, heat-shrink tube is easy to be out of shape after aging or split, like this, water in the water tank will be from the crack of heat-shrink tube or the binding site of heat-shrink tube and stainless steel sensor pipe, penetrate into sensor internal, make the work of water-temperature water-level sensing circuit malfunctioning, the serviceable life of inductor is shorter relatively.
Summary of the invention
Technical problem to be solved in the utility model is to propose the water-temperature water-level sensor of a kind of good operating stability, long service life.
For solving the problems of the technologies described above, the utility model water-temperature water-level sensor comprises water-temperature water-level sensing circuit, stainless steel sensor pipe, silica gel section and stainless steel sleeve pipe, described stainless steel sensor pipe spacer sleeve is connected in water-temperature water-level sensing circuit outside and with circuit, described silica gel section is located between described adjacent two stainless steel sensor pipes, the two ends of described silica gel section and described airtight linking to each other of stainless steel sensor pipe, described stainless steel sensor pipe inside is full of silica gel, and described silica gel and described silica gel section form one.
Above-mentioned water-temperature water-level sensor is at the two ends of described silica gel section, the junction of itself and described stainless steel sensor pipe is provided with fixing sleeve.
The utility model has been owing to adopted technique scheme, and it will the stainless steel sensor pipe be full of silica gel between inner and adjacent two stainless steel sensor pipes, is coated in silica gel section and the stainless steel sensor pipe the water-temperature water-level sensing circuit is airtight.Because silica gel itself is nontoxic, has good anti-corrosion, the breathing ratio is less between high low temperature, and anti-aging good with antioxygenic property, it is flexible, thereby can guarantee the stability of working sensor, has prolonged the serviceable life of sensor.The set fixing sleeve in silica gel section two ends can make between silica gel section and stainless steel sensor pipe be tightly connected more firm.
Description of drawings
Fig. 1 is the structural representation of the utility model water-temperature water-level sensor.
Embodiment
As shown in Figure 1, water-temperature water-level sensor comprises water-temperature water-level sensing circuit, stainless steel sensor pipe 1, silica gel section 2 and stainless steel sleeve pipe 3, stainless steel sensor pipe 1 spacer sleeve is connected in water-temperature water-level sensing circuit outside and with circuit, and silica gel section 2 is located between adjacent two stainless steel sensor pipes 1.The two ends of silica gel section 2 and 1 airtight linking to each other of stainless steel sensor pipe, its outside is provided with stainless steel fixing sleeve 4.The inside of stainless steel sensor pipe 1 is full of silica gel, and silica gel and silica gel section 2 form one (during making, behind stainless steel sensor pipe 1 inner injection silica gel fluid, adopting a compression moulding to form silica gel section 2 earlier).Stainless steel sleeve pipe 3 is located at the outside of stainless steel sensor pipe 1 and silica gel section 2, and its top links to each other with the stainless steel sensor pipe 1 of outermost side, and its sidewall is provided with inlet opening 5.
