Abstract
A cold and hot water mixing automatic constant temperature valve comprises a memory alloy spring 3, a balancing spring 4, and a piston 2. The axial movement of the piston 2 is driven by the reciprocity between the elasticity change generated by the reaction of the memory alloy spring 3 to the water temperature and the balancing spring 4 to achieve the adjustment of the size of a cold and hot water outlet opening, thereby realizing the constant temperature of the mixed water. The temperature of outlet water can be changed by setting the temperature knob 6.
Description
A kind of valve of automatic constant hot and cold water water-mixing temperature.Belong to valve and make the field.
Being mixed into our needed warm water with cold water and hot water often is needs.Mixed water valve is exactly a valve of realizing that this needs.Existing temperature regulation of mixing the water valve technology has manually and automatic two kinds.Manually temperature is regulated in the armrest sense, and the temperature that regulates is very big with the variation fluctuation of hot and cold water pressure in the pipeline.Adjusted good water temperature often becomes very uncomfortable when shower, even cold shock and scald accident take place.Automatic constant temperature valve can avoid above phenomenon to take place, but existing automatic constant temperature valve complex structure, with high costsly causes the too high and generally practicality of price.
The purpose of this utility model provides a kind of automatic thermostatic water mixing valve door design proposal simple in structure.Present technique is achieved in that and adopts spring that memory alloy material manufactures as temperature sensing and dynamical element that other adds the balance spring that a common material is made.Drive a piston between memory alloy spring and balance spring.When the mixing water temperature rises, memory alloy spring elastic force can increase the compression balance spring, drives piston to balance spring one side shifting, has so just turned down hot water inlet, simultaneously also opened greatly cooling water inlet, made water-mixing temperature decline and be tending towards setting temperature until balance.Otherwise if water-mixing temperature decline suddenly, memory alloy spring pressure can reduce, and the balance spring elongation drives piston and moves to memory alloy spring one side, makes hot water inlet open big cooling water inlet and turns down, and water-mixing temperature is risen also be tending towards setting temperature equally.If the change setting temperature only needs the decrement of adjustment spring to realize.
Figure of description is a sectional schematic, is described in detail below in conjunction with embodiment.
This thermostatic valve is mainly by forming with the bottom: overcoat 1, piston 2, memory alloy spring 3, balance spring 4, lid 5, setting temperature knob 6, swivel nut 7, mandrel 8, seal ring 9,10, feather key 11, depotition cock 12.Valve forms two chambeies by piston 2, chamber A and chamber B.
Temperature value can be set arbitrarily between 20 ℃-50 ℃.
