Description
Technical field: the utility model relates to a kind of band solar water heater and the gas water-heater combination compensates inlet valve with cold water, is mainly used in solar water heater and is connected with the pipeline of gas water-heater combination.
Background technique: in the prior art, the working principle of solar water heater and gas water-heater combination is that solar water-temperature is when higher than setting temperature, electric T-shaped valve in the pipeline is in the position that is connected with the hot water inlet of constant temperature mixed valve, outputs to user side after flowing through the solar water of constant temperature mixed valve and cold water mix; When solar water-temperature does not reach setting temperature, electric T-shaped valve is in the position that is connected with the cold water inlet of gas water-heater, and the combustion gas tool is flow through in the current break-in, and the combustion gas tool starts operation after detecting current, heated hot water flows to constant temperature mixed valve and cold water mix again, outputs to user side again.Higher but also do not reach customer requirements and under the gas ratio valve of gas water-heater regulates than limited situation at the solar energy water-exit temperature like this; gas water-heater can very little because of the heating space of hot water (even moving with the minimum power of water heater) still can produce superheating phenomenon; and gas water-heater has overtemperature protection system; gas water-heater can cut out after detecting superheating phenomenon automatically; so the frequent phenomenon of closing, start can appear in gas water-heater, the output hot water of user side also can produce sometimes hot and sometimes cold thereupon.For overcoming these defectives, the pipeline connection part of solar water heater and gas water-heater combination is developed.
Summary of the invention: technical problem to be solved in the utility model provides a kind of solar water heater and the gas water-heater combination compensates inlet valve with cold water, it can be avoided, and gas water-heater in the combination of solar water heater and gas water-heater frequently reciprocal cuts out, start-up course, thereby guarantees that output hot water does not have sometimes hot and sometimes cold phenomenon.
The technological scheme that its technical problem that solves the utility model adopts is: it comprises T type three-way pipe, intake pipe, intake pipe is connected to the mouth of pipe of three-way pipe crosspassage, it is characterized in that it also comprises heat responsive element, be provided with the positioning block of water inlet, be provided with the jacking block of water inlet, spring, be provided with the ring packing back-up ring in the transverse pipe of described three-way pipe, described heat responsive element one end is provided with the circular seal flange, the radius of sealing flange is greater than the internal diameter of Sealing shield ring, positioning block and jacking block are individually fixed in two connecting ends of intake pipe and three-way pipe, heat responsive element passes Sealing shield ring and is fixed on the positioning block, sealing flange is positioned at outside the Sealing shield ring, is connected with spring between heat responsive element and the jacking block.
Described heat responsive element is made by thermal expansion material.
Described heat responsive element is cylindric, and the radius of stylolitic part is less than the internal diameter of Sealing shield ring.
The radius of described sealing flange less than the internal diameter of three-way pipe greater than the internal diameter of Sealing shield ring.
Described three-way pipe and intake pipe are by being threaded.
The utility model is compared the beneficial effect that is produced with background technique:
1, the utility model provides a kind of solar water heater and gas water-heater combination to compensate inlet valve with cold water, increasing heat responsive element, positioning block, jacking block and spring in the T type three-way pipe now, open the cold water inlet of three-way pipe by the thermal expansion of heat responsive element, the hot water that enters three-way pipe is carried out the constant temperature compensation, it can be avoided, and gas water-heater in the combination of solar water heater and gas water-heater frequently reciprocal cuts out, start-up course, thereby guarantees that output hot water does not have sometimes hot and sometimes cold phenomenon.
Description of drawings: Fig. 1 is the utility model cross-sectional view.
Fig. 2 is an explosive view of the present utility model.
Fig. 3 is applied to annexation schematic representation in the combination of solar water heater and gas water-heater for the utility model.
Embodiment: referring to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, present embodiment comprises T type three-way pipe 1, intake pipe 2, heat responsive element 3, be provided with the positioning block 4 of water inlet, be provided with the jacking block 5 of water inlet, spring 6, be provided with ring packing back-up ring 8 in the transverse pipe of three-way pipe 1, heat responsive element 3 is made by thermal expansion material, the one end is provided with circular seal flange 7, the radius of sealing flange 7 is greater than the internal diameter of Sealing shield ring 8 and less than the bore of three-way pipe 1, positioning block 4 and jacking block 5 are individually fixed in two connecting ends of intake pipe 2 and three-way pipe 1, heat responsive element 3 passes Sealing shield ring 8, sealing flange 7 is blocked in outside the Sealing shield ring 8, spring 6 connects an end and the jacking block 5 of heat responsive element 3 band sealing flanges 7, the other end of heat responsive element 3 is connected with positioning block 4, the utility model is when off position, sealing flange 7 covers Sealing shield ring 8, makes the intake pipe 2 of cold water inlet end be closed state.
Working principle: the utility model is mainly used in solar water heater and the gas water-heater combination (shown in A among Fig. 3), when solar energy heat outputting coolant-temperature gage higher but when not reaching customer requirements, hot water flows to solar water heater and the gas water-heater combination compensates hot water with cold water compensation inlet valve, hot then, cold water mix, mix warm water and enter gas water-heater and heat, be heated to export after the default temperature and use for user side.Hot water injects from intake pipe 2, flow to three-way pipe 1 through the water inlet of positioning block 4, elongate behind heat responsive element 3 expanded by heating, closed state between original sealing flange 7 and the Sealing shield ring 8 is unlocked, heat responsive element 3 pressure springs 6 after expansion is elongated, this moment, cold water flowed into from the intake pipe 2 of the other end, enter three-way pipe 1 through the water inlet of jacking block 6, enter the center of three-way pipe 1 then by the space between sealing flange 7 and the Sealing shield ring 8, cold water mixes the vertical tube injection gas water-heater heating of back from three-way pipe 1 with hot water.
If solar water heater heat outputting coolant-temperature gage is than the preset temperature end slightly; then hot water is heated once more by gas water-heater; even gas water-heater is with minimum power work; the intensification space is also bigger than solar heat coolant-temperature gage and preset temperature difference; the superheat temperature that surpasses gas water-heater easily; can close automatically after gas water-heater with overtemperature protection system detects superheat temperature, this moment, the frequent reciprocal phenomenon of closing automatically, open can appear in gas water-heater.Hot water can be carried out the cold water compensation by cold water compensation inlet valve, make the mixing water temperature remain the scope that the gas water-heater Proportional valve is regulated, avoid gas water-heater to occur frequently back and forth closing, opening effectively, thereby the hot water of guaranteed user side can sometimes hot and sometimes cold phenomenon yet, has increased user's comfortable feel.
