Specific embodiment
As Figure 1-4, a kind of hot and cold water constant temperature valve core to be opened/closed, including outer cover body 1, inner shell body 2, sensor
3 and adjusting rod 4.
The endoporus 11 of described outer cover body 1 is the shoulder hole structure of multiple aperture, and it is divided into aperture sequentially to increase from top to bottom
Upper hole portion 111, middle hole portion 112 and lower hole portion 113, upper hole portion 111 therein and middle hole portion 112 junction form one and are used for adjusting
The convex platform 114 of stop bit is moved on section slide block, between middle hole portion 112 and lower hole portion 113, forms a lower convex platform 115.
Described inner shell body 2 is arranged on hole portion 113 under the endoporus of outer cover body 1, and for consideration easy for installation, described
Lower hole portion 113 side wall is provided with the stop bit boss 1131 installing inner shell body 2.Below the outer wall of described inner shell body 2 and shell
Body 1 inner hole thread connects, and is provided with some O-ring seals between the outer wall middle and upper part of inner shell body 2 and the endoporus of outer cover body 1
61.It is provided with cold water inlet hole 21, hot water inlet hole 22 and mixing water apopore 23 in described inner shell body 2.Inner shell body 2
Upper end is provided with central bore 24, inner periphery boss 25 and excircle boss 26, and the height of excircle boss 26 is higher than inner periphery
Boss 25.The water side of described cold water inlet hole 21 is located on excircle boss 26, the water side position of described hot water inlet hole 22
In the groove 27 between internal and external circumference boss 25,26, described mixing water apopore 23 and central bore 24 lead directly to.
Described adjusting rod 4 is positioned at outer cover body 1 top by slotted collar 41, and the bottom cooperation of adjusting rod 4 is installed
In the upper hole portion 111 of outer cover body 1 endoporus, and it is provided with O-ring seal 62 in both junctions.
Adjusting slider, the top of adjusting slider and adjusting rod 4 are installed in the middle hole portion 112 of described outer cover body endoporus 11
The connecting hole of bottom is threaded, here, cannot rotate, described middle hole portion for making adjusting slider can only be axially moveable
112 are correspondingly arranged into polygonized structure with adjusting slider, adopt regular hexagon in the present embodiment, in practice can be as needed
It is set as other polygons.The bottom periphery of described adjusting slider is provided with annular protrusion, and the lower end center of adjusting slider is provided with one
Installing hole 52, is provided with one by one by the pressure cap 71 of snap ring 53 or screw thread catch positioning in installing hole 52 and has certain pre compressed magnitude
Little spring 72, the bottom of pressure cap 71 mutually held with a push rod 73, the bottom of push rod 73 and hole portion under outer cover body endoporus
113 sensor 3 is fixedly connected, and the bottom of sensor 3 is less than the big spring of little spring 72 coefficient of elasticity by a coefficient of elasticity
74 are offseted with the bottom of inner shell body central endoporus 24, make little spring 72, pressure cap 71, push rod 73, sensor 3 and big spring 74 it
Between shape be in active relationship.
The middle part periphery of described sensor 3 connects a pulley 8, the excircle boss 26 of the outer wall of pulley 8 and inner shell body 2
Inner wall sealing be connected, and both junctions be provided with O-ring seal 63 to ensure both connect sealing.Entirely
The height of pulley 8 be less than inner shell body 2 upper end inner periphery boss 25 arrive outer cover body endoporus 11 lower convex platform 115 between away from
Can offset with the sealing of described lower convex platform 115 with its upper surface when moving in sensor 3 synchronization from, described pulley 8, described pulley 8 with
When sensor 3 synchronization moves down, its lower surface can be offseted with inner periphery boss 25 sealing on described inner shell body 2.
When described adjusting slider moves down, the annular protrusion of its bottom periphery can be offseted with the upper end face seal of pulley 8.
Here, for ensureing the sealing when offseting for pulley 8 end face, the upper surface of pulley 8 with miscellaneous part corresponding position
The connecting portion offseting with described lower convex platform 115, annular protrusion is provided with O-ring seal 64, the lower surface of pulley 8 and inner shell body 2
Inner periphery boss 25 between also be provided with O-ring seal 65.
It is provided with the guide hole 81 of some connection upper and lower end faces in described pulley 8.
In use, when the annular protrusion of adjusting slider bottom periphery is not offseted with pulley 8 upper surface, whole valve element
It is in thermostatic control state, now the upper and lower end face of pulley 8 is all left into water space, now cold water passes through in inner shell body 2
Cold water inlet hole 21 is flowed out by the water side on excircle boss 26, flows through afterwards in pulley 8 upper surface and outer cover body endoporus
Gap entrance pulley 8 upper surface between lower convex platform 115, and flowed to the lower surface of pulley 8 by the guide hole 81 in pulley 8, simultaneously
Hot water is by the hot water inlet hole 22 in inner shell body 2 by going out in groove 27 between excircle boss 26 and inner periphery boss 25
Water end (W.E.) flows out, flow through afterwards gap between pulley 8 lower surface and inner shell body inner periphery boss 25 enter pulley 8 lower surface with
Cold water mix, and mixing water flows to mixing water apopore 23 by the central bore 24 of inner shell body 2.
In the above process, sensor 3 therein can occur thermal expansion contraction distortion according to the temperature of mixing water.Because of little bullet
The coefficient of elasticity of spring 72 is more than the coefficient of elasticity of big spring 74, and movable pulley 8 will be carried to move down when mixed water temperature spends high, and then
So that the gap between the lower convex platform 115 in pulley 8 upper surface and outer cover body endoporus 11 is increased, make pulley 8 lower surface and inner shell
Gap between internal circumference boss 25 diminishes, and increases cold water and intakes and reduce hot water water inlet, so that the temperature of mixing water is reduced to
Suitable temperature, realizes constant-temperature effluent；When mixed water temperature spends low, sensor 3 will shrink, and band movable pulley 8 moves, and then makes
The water space that enters of pulley 8 upper surface reduces, and makes the water space that enters of pulley 8 lower surface become big, reduces cold water and intake and increase hot water
Water inlet, makes the temperature of mixing water be increased to suitable temperature, realizes constant-temperature effluent.
And when needing to completely close valve element, adjusting rod 4 can be passed directly to, by its threadeding with adjusting slider,
Drive adjusting slider to move down, continue to move down when the annular protrusion of adjusting slider bottom periphery is offseted with the upper surface of pulley 8, should
Process is offseted with the inner periphery boss 25 of inner shell body 2 until the lower surface of pulley 8, now the hot and cold water of pulley 8 upper and lower end face
Enter water space all to close, realize the on-off control to hot and cold water.And when needing to open valve element it is only necessary to rotate backward adjusting rod
4, make to move on adjusting slider.
To sum up, the hot and cold water constant temperature valve core to be opened/closed of present invention design, it not only can be carried out to hot and cold water flow of inlet water
Proportion adjustment, can carry out on-off control to the water inlet of hot and cold water simultaneously, gathered thermostatic control and on-off control in one, had
Simple and practical feature, can effectively reduce the volume Manufacturing cost of constant-temperature tap, and very generous for actually used offer
Just.
The above, be only the better embodiment of the present invention, and not invention is made with any pro forma restriction, every according to
According to the present invention know-why to any simple modification made for any of the above embodiments, equivalent variations or modification, still fall within the present invention
In the range of technical scheme.
