The special valve core has the function of keeping the water temperature constant.
Description
Technical field
The utility model relates to a kind of spool, relates in particular to a kind of special-purpose spool of the stable constant-temperature tap of water temperature constant temperature that keeps.
Background technique
At present, the major defect of the solar water heater on the market, electric water heater, the special-purpose spool of boiler is that control water temperature is stable inadequately, changes with regard to occurrence temperature such as work as the hydraulic pressure instability, makes water-exit temperature can not reach setting temperature, causes sometimes hot and sometimes cold; When the hot water water temperature is unstable, also sometimes hot and sometimes cold phenomenon can appear, and the user is when using water heater to take a shower or when using boiler, and it is stable that water temperature can not keep, and so just brought inconvenience for the user; In addition when the user uses solar water heater to take a shower, the hot water water route that a water route is arranged is solar energy, one is the tap water water route, when tap water is cut off the water supply, and the hot water flow of solar water heating pipe so just causes the serious consequence of scalding the people easily still toward dirty.
The model utility content
The technical problem that the utility model solved is the defective that overcomes prior art, provides a kind of cocoa to keep the stable special-purpose spool of water temperature constant temperature.
For solving the problems of the technologies described above, the special-purpose spool of a kind of constant-temperature tap, comprise the spool main body that has cavity, in the cavity of spool main body, be connected with the fuse four-head in turn, pressure cap, long spring, long spring seat, spring seat, piston plate, big spring, regulator, the spool main body is provided with cooling water inlet and the hot water inlet that is communicated with cavity, end at described regulator is provided with the constant temperature rod, one end of described piston and the spring seat of described long spring be apical grafting mutually, its the other end is connected with an end of constant temperature rod, the other end of described constant temperature rod passes described regulator, extend to the described spool main body outside, described constant temperature rod is connected with described regulator; Be set with piston plate on described piston, described regulator is connected by described big spring with described piston plate, and described piston plate is located in the cavity of the spool main body between described cooling water inlet and the described hot water inlet.
Wherein, between long spring and the spring seat, between long spring seat and the spool main body, be provided with O type circle between base and the big spring.
Owing to adopt above-mentioned technological scheme, the utlity model has following beneficial effect: owing to be provided with thermally sensitive constant temperature rod, the physical property of expanding with heat and contract with cold by the constant temperature rod, drive piston plate and in the cavity of spool main body, move back and forth, and then realize the beneficial effect of control automatically and maintenance water temperature stability.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
1, pressure cap; 2, long spring; 3, piston plate; 4, constant temperature base; 5, piston; 6, constant temperature rod; 7, the fuse four-head falls; 8, jump ring; 9, spool main body; 10, wear washer; 11, long spring seat; 12, O type circle; 14, spring seat; 17, cooling water inlet place; 20, hot water inlet place; 21, big spring; 22, base; 24, regulator.
Embodiment
Below in conjunction with accompanying drawing embodiment is illustrated.
As shown in Figure 1, the special-purpose spool of the utility model constant-temperature tap, comprise the spool main body 9 that has cavity, be connected with in the cavity of spool main body 9 that the fuse four-head falls 7 in turn, pressure cap 1, long spring 2, long spring seat 11, spring seat 14, piston plate 3, big spring 21, regulator 24, the spool main body is provided with cooling water inlet 17 and the hot water inlet 20 that is communicated with cavity, is provided with constant temperature rod 6 at an end of described regulator.
Wherein, between long spring 2 and the spring seat 14, be provided with O type circle between long spring seat 11 and spool main body 9, base 22 and the big spring 21.
When using, when the user is set in 38 ℃ with the temperature of regulator, constant temperature rod 6 is because the rotary temperature scale of regulator 24 is communicated on the inner constant temperature rod bar, constant temperature rod bar is experienced water temperature, when the internal mix water temperature has only 10 ℃, because water temperature is cold excessively, (principle of constant temperature rod bar) because of expanding with heat and contract with cold, constant temperature rod bar shrinks, shrink and drive big spring 21, the piston plate 3 that big spring 21 drives on the piston 5 again shrinks, and the contraction of piston plate 3 moves to blocks cooling water inlet, and cold water can not enter, have only hot water to enter this moment water temperature inside is raise, when water temperature reached 38 of setting and spends, piston plate was because the principle of expanding with heat and contract with cold just in time is in the middle of hot water inlet and the cooling water inlet, and moving up and down of piston plate played the effect of balancing water temperature.That is to say that water temperature is too hot, piston plate is blocked hot water inlet; Water temperature is too cold, and piston plate is blocked cooling water inlet; When water temperature reached 38 ℃ of the temperature of setting, piston plate was in (this moment, 2 water routes can enter) in the middle of cooling water inlet and the hot water inlet.It is constant that the back and forth movement of piston plate is regulated water temperature continuously.
When tap water was cut off the water suddenly, hot water entered and makes constant temperature rod bar 6 expanded by heating in seconds block hot water inlet, thereby can not scald the shower user in addition.
This constant temperature valve core can not change the constant temperature ability because of the variation of hydraulic pressure.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
