Abstract
A kind of temperature control cold water is from valve.Comprise spool, temperature-sensitive temperature control spring, pressure adjusting spring, Returnning spring, housing, drain port, pressure-regulating sleeve and pressure regulation bar.Especially adopt temperature-sensitive temperature control spring as temperature control element according to the action of setting temperature autocontrol valve core, excretion automatically switches to the temp .-control valve that hot water makes use after being trapped in the cold water in pipeline again.Described temperature-sensitive temperature control spring 2 is arranged in the draining runner of housing 8, and the spool 1 that can move axially pushes up pressure to drain opening 11, and Returnning spring 4 is coaxial and pulled to water nozzle 10 by spool with spool.Compressive state is under temperature sensing spring 2 normal temperature.When ambient temperature reach by pressure regulation bar 6 through screw thread promote pressure-regulating sleeve 5 and compress the setting value of pressure regulation spring 4 time, spool 1 is pushed to drain opening 11 by temperature sensing spring, opens water nozzle 10 simultaneously.Finish using when hot water and the water temperature of being detained reduces time, spool is pulled to close water nozzle to drain opening 10 again by Returnning spring 4 gradually, opens the cold water in discharge conduit when drain opening used in order to next time simultaneously.
Description
Technical field
The utility model relate to for after hot water supply system the cold water be trapped in pipeline is drained automatically at automatic thermostat valve hot water is switched to water place.
Background technique
At present, after the hot water be trapped in after common hot water supply system finishes using at every turn in pipeline cools off, next time first can go out cold water when using, especially the top spray head suspension of shower is in the human body crown, and switch is on metope, just opened the cold water that time lag of switching stays in pipeline and just poured human body from the crown, this drawback is extremely annoying, even causes a lot of the elderly or women and children dare not use top spray shower.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of easy reliable temperature control cold water from valve, hot water is automatically switched to the temp .-control valve with water place again after especially adopting temperature-sensitive temperature control spring with setting temperature and automatically excretion being trapped in pipeline cold water as temperature control element according to setting temperature.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of temperature control cold water is from valve; Comprise spool, temperature-sensitive temperature control spring, Returnning spring, housing, drain port, adjustment sleeve and adjusting screw rod; It is characterized in that: described temperature-sensitive temperature control spring is arranged on the spool that can move axially in draining runner and presses to drain opening top, Returnning spring is coaxial and pulled to water nozzle by spool with spool, especially adopt temperature-sensitive temperature control spring as temperature control element and according to the action of setting temperature autocontrol valve core, excretion automatically switches to the temp .-control valve that hot water makes use after being trapped in the cold water in pipeline again; Described pressure regulation bar promotes pressure-regulating sleeve with screw thread and withstands spool to implement temperature adjustment; Described temperature-sensitive temperature control spring is arranged in draining runner the spool that can move axially and pulls to drain opening, and Returnning spring is coaxial and pressed to water nozzle top by spool with spool.
The utility model compared with prior art, there is following beneficial effect: when being detained a large amount of cold water in hot water supply system's pipeline, can first the cold water in pipeline be entered in flush toilet or cold-water tank from drain opening automatically after opening hot water tap, by the time just automatically hot water can be switched to when temperature reaches setting and use water place, shower head cold water especially can be avoided to drench the embarrassment of head.
Accompanying drawing explanation
Fig. 1 is that the utility model embodiment 1 temperature control cold water is from the main sectional view of valve temperature control top pressure valve cored structure.
Fig. 2 is that the utility model embodiment 2 temperature control cold water pulls the main sectional view of valve core structure from valve temperature control.
Embodiment
Embodiment 1: see Fig. 1, and the present embodiment mainly comprises spool 1, temperature-sensitive temperature control spring 2, Returnning spring 3, reset cap 4, adjustment sleeve 5, adjusting screw rod 6, drain port 7 and housing 8.
Described temperature-sensitive temperature control spring 2 is arranged in the draining runner of housing 8 by the present embodiment, and the spool 1 that can move axially pushes up pressure to drain opening 11, and Returnning spring 3 is coaxial and pulled to water nozzle 10 by spool with spool; Compressive state is under temperature sensing spring 2 normal temperature; When ambient temperature reaches setting value, temperature sensing spring pushes spool 1 to drain opening 11, opens water nozzle 10 simultaneously; When occluded water temperature drop is low with finishing for hot water, spool 1 pulls to water nozzle 10 again and closes by Returnning spring 3 gradually, opens the cold water in discharge conduit when drain opening 11 used in order to next time simultaneously; When adjusting screw rod 6 moves spool 1 to the end by adjustment sleeve 5, water nozzle 10 is forced closed and current can only flow out from drain opening; When adjusting screw rod 6 passes through adjustment sleeve 5 by time head-to-foot for spool 1, drain opening 11 is forced closed and current can only flow out from water nozzle 10.
Embodiment 2: see Fig. 2, and the present embodiment mainly comprises spool 12, temperature-sensitive temperature control spring 13, Returnning spring 14, pressure adjusting spring 15, pressure-regulating sleeve 16, adjusting screw rod 17, drain port 18 and housing 19.
The present embodiment basic structure and principle roughly the same with embodiment 1; Wherein difference is that the present embodiment changes temperature-sensitive temperature control spring 13 into pulling to spool 12, and Returnning spring 14 changes into and pressing the top of spool 12; Wherein in embodiment 1, the top pressure of pressure regulation spring 15 pairs of spools 12 is used in the pulling of adjustment sleeve 5 pairs of spools 1 instead.
Although the utility model with embodiment openly as above, it is also not used to limit protection domain of the present utility model; Top pull-up structure as spool is exchanged, the distortion of housing and runner, housing is with lifting bar or temperature adjustment or thermostatic valve is integrated, replace embodiment 2 pressure regulation spring structure with embodiment 1 spool afterbody; In a word, being anyly familiar with this technician, not departing from the change and retouching done in concept of the present utility model, protection domain of the present utility model all should being belonged to.
Claims (2)
1. a temperature control cold water is from valve, comprise spool, temperature-sensitive temperature control spring, Returnning spring, housing, drain port, pressure-regulating sleeve and pressure regulation bar is characterized in that: described temperature-sensitive temperature control spring is arranged on the spool that can move axially in draining runner and presses to drain opening top, Returnning spring is coaxial and pulled to water nozzle by spool with spool, described pressure regulation bar promotes pressure-regulating sleeve with screw thread and withstands spool to implement temperature adjustment, namely temperature-sensitive temperature control spring is adopted as temperature control element according to the action of setting temperature autocontrol valve core, excretion automatically switches to the temp .-control valve that hot water makes use after being trapped in the cold water in pipeline again.
2. temperature control cold water according to claim 1 is from valve, it is characterized in that: described temperature-sensitive temperature control spring is arranged in draining runner the spool that can move axially and pulls to drain opening, and Returnning spring is coaxial and pressed to water nozzle top by spool with spool.
