At present, Chinese patent discloses a kind of from water dress water valve [application number: 200520047918.8; Notice of authorization number: CN2861681Y], comprise valve group and blade assembly, described valve group comprises spool, compression plate, stage clip, spring seat, valve seat, described valve seat and described spool are arranged in this valve body the paddle hole place, be arranged with a stage clip between described spool and described valve seat, described stage clip is installed on a spring seat in nearly valve seat side, and described valve core housing is in compression plate.
In said structure, stage clip is to adopt memory alloy material to make, to have utilized the characteristic promotion spool of memory alloy material rising-heat contracting-cold to move the control water-outlet quantity, as a kind of simple temperature-controlling flow valve, it has solved that existing temperature servo type automatic water amount control device volume is excessive, complex structure, assembling difficulty, defective that cost of production is higher, but control water-exit temperature for required in ground heating system by mixing the hot water or cold water, above-mentioned obviously can't satisfy as a kind of one-sided control hot water flow from water dress water valve.
Summary of the invention
The purpose of this utility model has been to provide a kind of by automatically regulating hot water or cold water's ratio, reaches control water-exit temperature and simple in structure, a kind of automatic water-mixing valve that required temperature control adjusting part cost is low.
The purpose of this utility model is achieved in that
A kind of automatic water-mixing valve comprises the five-way valve body, it is characterized in that: the forward and backward both sides of valve body lower portion are respectively arranged with water outlet mouthpiece; The arranged on left and right sides of valve body lower portion is respectively arranged with into interface of hot water and advances the cold water interface; The right side on valve body top also is provided with the backwater interface, is provided with in the valve pocket in the middle part of valve body to be cellular spool, also is provided with in valve pocket to make spool generation upper and lower displacement enter the automatic control tegulatingdevice of water outlet mouthpiece to control the hot water or cold water.
In above-mentioned a kind of automatic water-mixing valve, the concrete structure of described automatic control tegulatingdevice is: be disposed with push rod, spring between the lower end of spool and valve pocket sidewall block, the top apical grafting of push rod has paraffin mass, copper pipe is established in the paraffin mass outsourcing, and described paraffin mass is heated to extend and can makes the downward displacement of push rod Compress Spring band movable valve plug.
In above-mentioned a kind of automatic water-mixing valve, described valve body upper end is provided with controlling mechanism, and described controlling mechanism is: adjusting knob can drive limit plunger and move up and down the height of controlling paraffin mass one end.
In above-mentioned a kind of automatic water-mixing valve, be plugged with sealing on described water outlet mouthpiece and block up.
The utility model outstanding and useful technique effect compared to existing technology is:
The utility model is to have utilized the principle of paraffin mass rising-heat contracting-cold to promote moving up and down of spool, wherein, the expansion of paraffin mass makes spool move down the flow that increases gradually hot water, when temperature reaches definite value, it is the certain-length that expand into of paraffin mass, cooling water inlet is opened in moving down of spool, make the interior temperature of valve pocket reduce gradually, paraffin mass shrinks, can effectively control in valve pocket water temperature in the certain limit value by this process, thereby realize the constant of supply water temperature in ground heating system, the utility model is simple in structure, supply water temperature can manually be set.
