Further, be integrated with temperature sensitive member in described fixture, can install by the mode of offering circular hole in fixture, this is easy to realize.
Further, each described temperature sensitive member, fixture are electrically connected to the control circuit part by lead respectively, connect in parallel, and the stainless-steel tube top also are electrically connected to the control circuit part by lead.
Described boss is radially equidistantly arranged along stainless-steel tube, carrying out water level control by the stage, satisfies the needs that day ordinary water level is regulated like this, and generally speaking, boss is made as 4 to 5 can satisfy normal use.
Described metal probe and fixture are one of aluminum casting, copper spare or stainless steel part.
Described syndeton is screw connection structure or buckle syndeton.
Described insulating washer is the tetrafluoro packing ring.
Be provided with water tank at described stainless-steel tube opening end and carry out flange connecting and seal.
Described stainless-steel tube is inserted in the water tank from top or the bottom of solar water heater water tank.
The beneficial effects of the utility model are: contact and the temperature of water is delivered on the temperature sensitive member by fixture by metal probe and water direct, make control circuit sense water temperature; Simultaneously, because the existence of insulating washer, make to have formed between metal probe and the stainless-steel tube and open circuit, formed a normal open circuit under anhydrous situation, had under the regimen condition, metal probe, water and stainless-steel tube form a current path, control circuit can receive, and carry out the laggard capable Digital Control of numeral conversion, and form the function of induction water level, efficiently solve water level and water temperature of solar water heater and measure inconvenient problem.
In the utility model, circuit part places the inside of stainless-steel tube fully, does not contact with water in the water tank, has avoided the influence of phenomenons such as fouling to temperature and liquid level induction, has serviceable life preferably.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A place partial enlarged drawing among Fig. 1;
Among the figure: 1 control circuit, 11 water temperature display circuits, 12 level measuring control circuits, 2 stainless-steel tubes, 3 fixtures, 31 O-ring seals, 32 sleeves, 33 spacer rings, 4 metal probes.
Embodiment
As shown in Figure 1 and Figure 2, the utility model, comprise control circuit 1, stainless-steel tube 2, fixture 3 and metal probe 4, described stainless-steel tube 2 is the uncovered round tube of an end shutoff one end, the shutoff end can form by the mode of welding end cap or global formation, its outside surface radially evenly is furnished with some boss, and the setting of boss is to be convenient to installation and the drilling technology of other parts.The positive center of boss has through hole, and through hole is communicated with the inside and outside of stainless-steel tube, forms a mounting hole, is used for mounting fixing parts.Fixture uses copper or stainless steel to make in fact near a screw, and metal probe is essentially a circular cylinder, adopts copper or stainless steel turning to form, and opens threaded hole in an end face of metal probe, and this threaded hole is blind hole.Fixture wherein at first passes outwards through from stainless-steel tube inside in the stainless-steel tube 2 behind the through hole, metal probe is locked by the threaded portion in the fixture outer end, wear and the locking process in, between fixture 3 and stainless steel inside pipe wall, place O-ring seal 31, between fixture and stainless-steel tube through hole, place sleeve 32, between metal probe and stainless-steel tube boss, place spacer ring 33, above-mentioned O-ring seal 31, sleeve 32 and spacer ring 33 all are the tetrafluoro materials, has insulation, the characteristics of non-scaling, can and rely on its sealing water to be completely cut off outside stainless-steel tube 2 effect of other insulating washers with metal probe 4 and stainless-steel tube 2 isolation.What expect easily certainly is above-mentioned three kinds of insulation components to be made an integral body also be fine.
Bore an aperture in the inside of fixture, laying temperature sensing element in the aperture is by contacting to gather water temperature with fixture direct.
