Specific embodiment
The content of the present invention is described in detail with specific embodiment with reference to the accompanying drawings of the specification:
As shown in Figs 1-4, the present embodiment provides a kind of dual control valve rods of thermostatic valve, for controlling hot water on constant temperature valve body
The connection of water inlet 5 and hot water outlet 6, cold water inlet 9 and cold water water outlet 8, including columned valve stem body 4, institute
It states valve stem body 4 and crosses water portion 1 and cold water crosses water portion 3 equipped with not connected hot water, the hot water crosses water portion 1 and cold water crosses water
Portion 3 is two deep gouges being staggeredly set on 4 periphery of valve stem body, is staggered refers to that hot water crosses water portion 1 and cold water here
Water portion 3 is crossed spatially without parallel relation, and hot water crosses water portion 1 and cold water crosses water portion 3 and spatially forms space angle,
Water portion 1 and water inlet of hot water 5 are crossed to change simultaneously hot water when realizing that valve stem body 4 rotates, cold water crosses water portion 3 and cold water inlet
9 overlapping area changes inflow in turn, and when the rotation of valve stem body 4, hot water inflow and cold water inflow are to be inversely proportional
Trend, cold water inflow is few when hot water inflow is more, and hot water inflow is few when cold water inflow is more.
In the present embodiment, in order to by rotation valve rod ontology 4 control hot water cross water portion 1 and cold water cross the conducting of water portion 3 or
Block water inlet of hot water 5 and hot water outlet 6, the cold water inlet 9 and cold water water outlet 8 of 4 two sides of valve stem body；The hot water
It crosses water portion 1 and cold water crosses the center line in water portion 3 and is each perpendicular to the axial line of valve stem body 4.
In the present embodiment, in order to realize the dual control regulatory function of valve stem body 4, i.e. rotation valve rod ontology 4 can be adjusted simultaneously
Section hot water crosses water portion 1 and cold water crosses the discharge area in water portion 3, and when the rotation of valve stem body 4, crosses water portion 1 and cold water mistake to hot water
The regulating degree of 3 discharge area of water portion is different；The groove depth of the deep gouge is slightly less than the radius of dual control valve rod.
It is different degrees of to hot water inflow and cold water inflow when in the present embodiment, in order to guarantee that valve stem body 4 is rotated
Adjustment keep constant temperature to guarantee to blend the water come, hot water crosses water portion 1 and cold water crosses water portion 3 and is staggered, valve body 7
Water inlet of hot water 5 and cold water inlet 9 are axially disposed on same straight line along valve stem body 4,4 adjusting angle of rotation valve rod ontology
Degree, when the inflow that the hot water crosses water portion 1 is maximum inflow, the inflow that the cold water crosses water portion 3 is zero, hot water
It crosses water portion 1 to be completely coincident with water inlet of hot water 5, cold water is crossed water portion 3 and is not overlapped completely with cold water inlet 9；When the cold water mistake
When the inflow in water portion 3 is maximum inflow, the inflow that the hot water crosses water portion 1 is zero, i.e., cold water cross water portion 3 and cold water into
The mouth of a river 9 is completely coincident, and hot water is crossed water portion 1 and is not overlapped completely with water inlet of hot water 5；When the inflow that the hot water crosses water portion 1 is
When the half of maximum inflow, the cold water crosses the inflow in water portion 3 for the half of maximum inflow, at this point, hot water crosses water portion 1
There is half to be overlapped with water inlet of hot water 5, cold water, which crosses water portion 3, has half to be overlapped with cold water inlet 9.
In the present embodiment, in order to separate hot water and cold water；The hot water crosses water portion 1 and cold water crosses the edge ring in water portion 3
Equipped with for the sealing ring with the sealing cooperation of valve body 7.
In the present embodiment, in order to separate hot water and cold water；It is equipped in the valve stem body 4 and crosses water portion 1 positioned at hot water
And cold water is crossed for separating the sealing ring 2 of hot water region and cold water zones between water portion 3, the valve stem body 4 is equipped with and is used for
The annular mounting groove of sealing ring is installed.
The utility model controls the constant temperature work of thermostatic valve by control unit, and mixing chamber 10, hot water is arranged in valve body 7
Water outlet 6, cold water water outlet 8 are connected to mixing chamber 10, and valve stem body 4 is rotatably installed in valve body 7, are driven by motor and are turned
It is dynamic, the rotational angle that position sensor detects valve stem body 4 is set in valve stem body 4, temperature sensing is set in mixing chamber 10
Device detects 10 water temperature of mixing chamber, and wherein motor, position sensor and temperature sensor are electrically connected with control unit, when temperature passes
When sensor detection temperature is too low, the rotation control hot water of motor driven valve stem body 4 is crossed the expansion of water portion 1 and is overlapped with water inlet of hot water 5
Area, synchronous, cold water crosses water portion 3 and reduces the area being overlapped with cold water inlet 9, thus the increase of hot water inflow, cold water
The temperature of decreased influent flow, mixing chamber 10 increases, and control unit determines motor stalls also by the feedback of temperature sensor
It is to continue with rotation；When temperature sensor detects when the temperature is excessively high, the rotation control cold water of motor driven valve stem body 4 crosses the expansion of water portion 3
The area being overlapped with cold water inlet 9 greatly, synchronous, hot water crosses water portion 1 and reduces the area being overlapped with water inlet of hot water 5, thus
Cold water inflow increases, hot water decreased influent flow, and the temperature of mixing chamber 10 reduces, the feedback that control unit passes through temperature sensor
Determine that motor stalls still continue to rotate, here, the rotation of valve stem body 4 only beat in a certain range repeatedly rotates
After adjustment, control unit records the water temperature measured after each rotational angle, and the thermostatic valve of data control based on this is kept
Perseverance control to water temperature, use are more convenient.
The above description is only the embodiments of the present invention, is not intended to limit the scope of patent protection of the utility model,
Equivalent structure or equivalent flow shift made by using the description of the utility model and the drawings, is directly or indirectly transported
Used in other related technical areas, it is also included in the patent protection scope of the utility model.
