Abstract
The utility model relates to an automatic adjusting valve for the water temperature of a shower, belonging to an automatic adjusting device for water temperature. The utility model is characterized in that temperature sensing element is a memory alloy spring which is clamped between a valve body and the barrel bottom of valve core; at an initial state, the hot water inlet of the valve core is communicated with the hot water inlet pipe of the valve body, and the cold water inlet of the valve core is positioned at the lower end of the cold water inlet pipe of the valve body; screws which are locked on the valve body are arranged in a guiding groove on the wall of the valve core, and a temperature adjusting spring whose two ends are pressed by pressing pieces is arranged at the top end of the valve core; the movements of an upper pressing piece is controlled by a temperature adjusting knob through a screw bolt. The device has the advantages of small heat inertia, high sensitivity, good temperature stability and long service life.
Description
The shower water automatic temperature control valve belongs to civilian water temperature automatic regulating device and makes the field.
Cause that volumetric expansion makes actuator's action realize that with the ratio that changes the hot and cold water yield water temperature is self-regulating thereby mostly present shower water automatic temperature control device is to utilize the solid-state temperature-sensitive thing that is contained in the temperature sensor can undergo phase transition under hot water or steam indirectly-acting.As: the low-melting point medium of paraffin wax one class of can in bellows, packing into, the solid-state temperature-sensitive mixture of also can in the rigidity temperature sensor, packing into, the common drawback of this class device is: its thermal inertia is big, poor sensitivity; Can not guarantee that when cold water or hot water interrupt suddenly modulating valve cuts out voluntarily, shower water quenching or shock heating phenomenon can occur, promptly its temperature stability is poor; The poor reliability of bellows, the life-span is short.
The purpose of this utility model just is to provide the shower water that a kind of thermal inertia is little, temperature stability good, reliability is high automatic temperature control device.
Feature of the present utility model is: its heat responsive element is the memory alloy spring of tube at the end that is clipped in valve body and spool, under original state, the hot water inlet of regulation valve core one side communicates with the hot water inlet pipe on the valve body, and the cooling water inlet on the spool tube wall is positioned at out the cold water inlet lower end on the valve body barrel and interlaces.The spool opposite side has a guiding groove, screw is on the valve body barrel and pass groove, the temperature adjustment spring that the top of spool has a two ends pressed sheets to push down, its lower sheeting and spool top join, last compressing tablet then pressurized has square section temperature adjustment screw rod in the guide ring of square hole in inserting, its top is threaded with a thermoregulation knob that is embedded in the ring-type location piece, this location piece contacts with the guide ring top and by being locked on the valve body with screw, and the shower water outlet pipe is opened at the bottom of the valve body tube and welded mutually with it.Be used to store hot water at that section that is positioned at valve body and can have spilled water hole on the shower water outlet pipe tube wall that increases its holdup time.
Use proof: its shower water temperature is adjustable and can keep constant; Its modulating valve can cut out automatically when cold water or hot water interrupt suddenly; Water temperature can not regulated continuously and can be undergone mutation.
In order in conjunction with the embodiments the utility model to be done detailed description below, now as follows employed accompanying drawing title of present specification and numbering brief introduction:
Fig. 1, shower water automatic temperature control valve sectional arrangement drawing.
Embodiment:
Ask for an interview Fig. 1.The 1st, thermoregulation knob; The 2nd, the temperature adjustment screw rod that is threaded with it; The 3rd, embed the thermoregulation knob lower end and be locked in ring-type location piece on the valve body by screw; The 4th, cylinder valve; The 6th, be clipped in the temperature adjustment spring between compressing tablet 5 and the lower sheeting 7; The 8th, pressurized is in the cylindrical shape spool of lower sheeting, and the 9th, be used for the guiding groove on the locking spool barrel and the guider screw of valve body barrel; The 10th, open the hot-water line on the valve body barrel, it communicates with hot water inlet pipe on the spool barrel under original state, and the 11st, at the memory alloy spring of tube at the end of spool and valve body, make heat responsive element and use; The 12nd, open shower water outlet pipe at the bottom of the valve body tube, it welds at the bottom of with this mutually; Be positioned on that section shower water water outlet tube wall of valve body and have many spilled water holes, 13 is one of them; The 14th, the guiding piece that is passed from square hole by square section temperature adjustment screw rod; The 15th, the insulation filler that makes with polyphenyl foam between valve body and shell 16; The 17th, open the cold water inlet on the spool barrel; The 18th, open the cold water inlet on the valve body barrel.
Water tap (not drawing on the figure) below being positioned at the shower water outlet pipe is when closing, be in hot water under the original state at modulating valve and enter spool 8 and the bottom of letting out valve body down goes direct heat transfer to give memory alloy spring 11 from intake pipe 10, when water temperature reaches the phase transition temperature of giving the memory alloy spring of setting earlier, spring will extend, the promotion spool moves up to reduce the hot water inlet along the guiding groove of its barrel, when opening at the cold water inlet on the spool barrel 17 when opening cold water inlet 18 on the valve body barrel and intersect, cold water just begins to flow into the valve body bottom by spool.When if water temperature still is higher than the temperature of setting, spool can continue to rise and so that increasing cold water inflow reduces the hot water inflow simultaneously water temperature decline be reached till the setting temperature.When demand changes water temperature, can make the temperature adjustment screw rod move down the method that forces spool to move down with compression temperature adjustment spring by the rotation thermoregulation knob and realize.If in use hot water interrupts suddenly, memory alloy spring can be restored rapidly, closes cooling water inlet automatically.If cold water interrupts suddenly, water temperature can substantially exceed setting temperature, makes memory alloy spring elongation suddenly remove to close voluntarily hot water inlet.Avoided the jumping phenomenon of water temperature.The stability of shower water temperature and the sensitivity that water temperature is regulated have been guaranteed in addition.
The effect of spilled water hole is to make the residuary waters in the valve body can be from wherein outwards draining among Fig. 1.
