Device connects, and its opposite side is provided with the snap joint being structure as a whole with thermoregulator valve body 102.
The top of cavity 112 is provided with opening, and the end cap 101 that opening is installed by sealing is closed.Tool
The bonnet assemblies structure of body is as shown in Figure 3 and Figure 4: end cap 101 one end open, opening of end cap 101
Mouth end is internal towards cavity 112, is provided with the first spring 203, the opening of end cap 101 in end cap 101
End is provided with hard-wired back-up ring 121, and one end of the first spring 203 crimps with end cap 101, and first
The other end of spring 203 is pressed into contact with back-up ring 121.
Concrete, the first end of the body of thermostatic element is pressed into contact with the opening of end cap 101, heat
The other end of the body of dynamic element is provided with the second spring 206 being in compressive state.
Concrete, when the initial deformation power of the first spring 203 is enclosed more than the 3rd interface 106 second
Pressure suffered by spring 206.Heat-sensitive materials expanded by heating when meeting this condition, in thermostatic element
Time, thermostatic element just can first move until blocking the 3rd interface 106 to the direction of the 3rd interface 106.
Hereafter push rod 205 is caused to pierce through the elastic in thermostatic element in order to prevent heat-sensitive materials from continuing to expand
Part, is provided with the second bullet when initial deformation power is enclosed more than the 3rd interface 106 inside end cap 101
First spring 203 of the pressure suffered by spring 206, after the 3rd interface 106 is enclosed, temperature-sensitive thing
It is right to alleviate push rod 205 that the produced power of matter continuation expansion be enough to promote the first spring 203 to produce deformation
The active force of thermostatic element inner resilient members.
The first spring 203 that the cover internal of the present invention is arranged can reduce thermoregulator to designer and bullet
The requirement of spring aspect of performance.Relative to existing moveable capping be arranged on capping two of both sides
Spring, the end-cap assembly of the present invention makes the design of thermoregulator, installation simpler.And the end of the present invention
Cap assemblies makes be extended the service life of thermoregulator.
Concrete, it is provided with spring seat 111, push rod 205 between the first spring 203 and back-up ring 121
Be pressed into contact with the first spring 203 by spring seat 111, spring seat 111 respectively with the first bullet
Spring 203 and back-up ring 121 are pressed into contact with.
Concrete, spring seat 111 is in straw hat shape, and the end of one end that push rod exposes is positioned at spring base
In the cavity of seat 111, push rod 205 is structure as a whole with spring seat 111, assembly 131 and gear
Circle 121 is structure as a whole.
In the preferred embodiment of end-cap assembly, the opening of end cap 101 is provided with and is secured to connection
Assembly 131, assembly 131 substantially cylindrical shape in both ends open, back-up ring 121 is fixedly mounted on
On the inwall of assembly 131, one end of the first spring 203 crimps with end cap 101, the first spring 203
The other end crimp with spring seat 111, spring seat 111 is pressed into contact with back-up ring 121, push rod
205 are structure as a whole or Split type structure with spring seat 111.Assembly 131 and back-up ring 121 also may be used
To be structure as a whole.During the present embodiment actually used, performance is more excellent, good sealing effect.
As depicted in figs. 1 and 2, in the thermoregulator of the present invention: the second end of the body of thermostatic element sets
Having spring mountings 217, the outer sidewall diameter of the body of thermostatic element is interior more than the 3rd interface 106
Footpath, the external diameter of spring mountings 217 is less than the internal diameter of the 3rd interface 106, the one of the second spring 206
Holding be connected fixing with spring mountings 217, its other end is pressed into contact with valve body 102 inwall.Heat is dynamic
When element is heated, body moves until body is blocked to the 3rd interface 106 under the promotion of heat-sensitive materials
3rd interface 106.When heat-sensitive materials continues to expand, the first spring 203 starts compression, push rod 205
Move up.
