Description of drawings
Sectional drawing when Fig. 1 is water flow sensing unit water outlet aperture maximum provided by the invention;
Fig. 2 is water flow sensing unit water outlet aperture provided by the invention sectional drawing hour;
Fig. 3 is the structural representation of current limliting joint in the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is made detailed explanation.
As shown in Figure 1, the water flow sensing unit of gas water-heater provided by the invention comprises housing 10, housing 10 is provided with water intake 11 and water outlet 12, be provided with current sensory package 13 in housing 10, the effect of current sensory package 13 is: when there being current out-of-date, current sensory package 13 sends the startup control signal, automatically opens gas control valve and the igniter of gas water-heater, and gas water-heater is started working; Otherwise, do not have current out-of-date, current sensory package 13 sends the closing control signal, the gas control valve of automatic self-closing gas water heater and igniter.
Innovation of the present invention is to be provided with the water-outlet quantity automatic control tegulatingdevice in the water outlet 12 of water flow sensing unit, be used for automatically controlling according to the water flow temperature of the water flow sensing unit of flowing through the water-outlet quantity of water flow sensing unit, thereby change the inflow of gas water-heater, to guarantee the effluent temperature constancy of gas water-heater, avoid occurring the situation that the water outlet in winter is excessively cold, the water outlet in summer is overheated.
The water-outlet quantity automatic control tegulatingdevice comprises current limliting joint 21, spool 22 and memory alloy spring 23.
As shown in Figure 3, current limliting joint 21 has an axial hole, and the inwall of axial hole is provided with a current limliting catch 25 that is disposed radially, and current limliting catch 25 forms flow channel with the inwall intersection of axial hole along circumferentially being laid with a plurality of through holes 31.
The two ends of memory alloy spring 23 are fixing with current limliting joint 21 and spool 22 respectively.
When the coolant-temperature gage of the water flow sensing unit of flowing through is higher (for example summer), memory alloy spring 23 elongations, band movable valve plug 22 descends, so, distance between the upper end of spool 22 and current limliting catch 25 strengthens, the water outlet aperture of spool 22 increases, the sectional drawing when Fig. 1 shows water flow sensing unit water outlet aperture maximum; Otherwise, when the coolant-temperature gage of the water flow sensing unit of flowing through hangs down (for example winter), memory alloy spring 23 shortens, band movable valve plug 22 rises, so, distance between the upper end of spool 22 and current limliting catch 25 reduces, and the water outlet aperture of spool 22 reduces, and Fig. 2 shows water flow sensing unit water outlet aperture sectional drawing hour.Thereby realized automatically controlling water-outlet quantity according to water flow temperature.
The means of fixation of memory alloy spring 23 can adopt following structure:
The axial hole lower ending opening place of current limliting joint 21 is provided with lower large little step hole, collar 26 spiral shell dresses in spring location are fixed on the major diameter section of step hole, the minor diameter of step hole is provided with back-up ring 29, the profile of spool 22 is sleeve-shaped, and the lower end outer side surface is provided with the first annular flange flange 27, the lower end surface of spring location collar 26 is provided with an annular groove, the upper end of memory alloy spring 23 is placed in spring and locates in collar 26, and fix with the sidewall close-fitting of annular groove, memory alloy spring 23 lower end abutment are on the first annular flange flange 27.Adopt this structure, simplified on the one hand the processing technology of component, on the other hand, the upper-lower position of spring location collar 26 is adjustable, closely can adjust the initial position of spool 22, to adapt to the error of memory alloy spring 23, guarantee effective control of spool aperture.
In addition, the lower end of water outlet 12 inwalls has an annular table terrace 28, and when spool 22 was in maximum opening, the lower end surface of the first annular flange flange 27 was resisted against on step surface 28, thus the maximum opening of restriction spool 22.
Radially perforation through hole 30 on spool 22 can be realized the aperture according to variation in water pressure regulating spool 22.
The upper end outer side surface of spool 22 is provided with the external diameter of the second annular flange flange 32, the second annular flange flange 32 greater than the internal diameter of back-up ring 29, with the raising sealing effect, and prevents spool 22 excessive descent.
Structure according to the water flow sensing unit of above-mentioned gas water-heater, the present invention also provides a kind of water-outlet quantity automatic control tegulatingdevice of water flow sensing unit, comprise current limliting joint 21, spool 22 and memory alloy spring 23, in view of this water-outlet quantity automatic control tegulatingdevice has been described in detail in aforementioned water flow sensing unit, therefore no longer repeat to introduce.
The present invention has following advantage: the water flow sensing unit that said structure is installed on the inlet/outlet pipe of gas water-heater, utilize the water-outlet quantity automatic control tegulatingdevice in the water flow sensing unit water outlet, can be automatically according to being cold warm color tone gas fuel saving water outlet of water heater flow, when season summer in winter conversion, do not need the manual switchover water yield, winter water can not appear not hot, the overheated situation of water in summer.In addition, the present invention is simple in structure, does not rely on expensive and complicated electron controls technology and controls the water yield, and cost of production is low.
The present invention is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under the enlightenment of invention, and every have identical or close technological scheme with invention, within all falling into the protection domain of invention.
