Abstract
A temperature sensing bulb is characterized in that a shell consists of an annular concave and convex surface made of a red copper material, a cylinder is arranged in the center of the inner bottom surface of the shell, space between the inner wall of the shell and a rubber sleeve at the upper end of the shell is filled with sensitive wax, a plug is arranged on the top of the shell, and an ejector rod penetrates through the center of the plug and is connected with the center of the rubber sleeve. Through thermal expansion and cold contraction of the wax, the ejector rod is driven to move to adjust the sizes of a cold water inlet and a hot water inlet, and the constant-temperature effect is achieved. The shell of the wax type temperature sensing bulb consists of the concave and convex surface, the short cylinder is placed in the bottom of the shell, by the structure, heating area is increased, the heat conduction efficiency of the wax type temperature sensing bulb is improved, and water temperature can be sensitively controlled to be constant.
Description
Technical field
The present invention relates to a kind of temperature-sensitive bag, particularly relate to a kind of performance of expanding with heat and contract with cold utilizing wax to control the temperature-sensitive bag of thermostatic valve hot and cold water inlet's size.
Background technology
Thermostatic valve is because of its simple in construction, it is not necessary to external force drives, and relies on wax formula temperature-sensitive bag to expand with heat and contract with cold performance to control the aperture of cold and hot water inlets, thus controlling outlet temperature, is widely used in internal-combustion engine cooling system and bathing, and petrochemical industry is medium.The domestic research to wax formula temperature sensing device starts from nineteen seventies.Water temperature can be controlled in setting value by the design of water mixing valve temperature-sensitive, and when water temperature is higher than setting value, wax starts to melt volumetric expansion and promotes temperature-sensitive pack arrangement to move the aperture controlling the cold and hot mouth of a river by push rod, keeps constant temperature;When water temperature is lower than setting value, wax starts solidification. and volume-diminished, built-in spring starts the movement adjusting temperature sensing device to control hot and cold water opening degree size, keeps constant temperature.This just require when variations in temperature wax can high efficiency variable condition, with the temperature control effect reached.Current domestic mainly have red copper wax formula temperature-sensitive bag and rustless steel wax two kinds of devices of formula temperature-sensitive bag.Although their heat conductivility is fine, but due to the problem of design in the structure of above two device, cause the reaction of variations in temperature is had certain hysteresis quality.
Summary of the invention
Present invention aim at providing a kind of wax formula temperature-sensitive pack arrangement for defect of the prior art, improve the heat conductivility of temperature-sensitive bag, improve thermostatic valve temperature control effect.
For achieving the above object, this temperature-sensitive pack arrangement includes housing, temperature-sensing wax, high sealing rubber sleeve, plug, cylinder, annular concave-convex face and push rod, the annular concave-convex face that described housing is made up of red copper material is constituted, described housing inner bottom surface center is provided with cylinder, in described housing, upper end is provided with rubber sleeve, it is filled with temperature-sensing wax between described inner walls and upper end rubber sleeve, case top is provided with plug, described plug abuts with described rubber sleeve, and described push rod is connected through plug center with the center of rubber sleeve.This annular concave-convex mask has zigzag continuous surface, and concave surface and convex surface are arranged alternately continuously, and the length of each concave surface and convex surface is equal.
The present invention is compared with background technology, and what have has the advantages that: this temperature-sensitive bag, and its housing red copper processes, and temperature zone surface configuration male and fomale(M&F), the built-in one section of cylinder in bottom, this configuration increases absorption heat area, improve temperature-sensitive bag sensitivity.In work process, the wax in temperature-sensitive bag is by carrying out heat transmission with outside, and expanding with heat and contract with cold of wax makes push rod elongation shorten, and controls cold and hot water inlets aperture.

Detailed description of the invention
As shown in Figure 1, a kind of temperature-sensitive bag, including housing (4), temperature-sensing wax (3), high sealing rubber sleeve (2), plug (1), cylinder (5), annular concave-convex face (6) and push rod (7), the annular concave-convex face (6) that described housing (4) is made up of red copper material is constituted, described housing (4) inner bottom surface center is provided with cylinder (5), described housing (4) interior upper end is provided with rubber sleeve (2), temperature-sensing wax (3) it is filled with between described housing (4) inwall and upper end rubber sleeve (2), housing (4) top is provided with plug (1), described plug (1) abuts with described rubber sleeve (2), described push rod (7) is connected through plug (1) center with the center of rubber sleeve (2).
As in figure 2 it is shown, this annular concave-convex mask has zigzag continuous surface, and concave surface and convex surface are arranged alternately continuously, and the length of each concave surface and convex surface is equal.
In the present embodiment, the housing of temperature-sensitive bag adopts red copper, and its temperature sensitive property is strong, and housing is configured with the shape of male and fomale(M&F) simultaneously, and housing bottom is provided with cylinder, and such structure increases contact area, the thawing coagulation efficacy of wax is made to be greatly improved.
This concrete installation method of temperature-sensitive bag is:
First, calculate the consumption of wax according to push rod moving range, take appropriate paraffinized sample heating and melting in annular seal space and become liquid to filling up annular seal space, extrude bubble, be cooled to room temperature.
Second, because after cooling, paraffin volume can reduce, then start to screw top cover after adding appropriate paraffin, unnecessary paraffin can be extruded from aperture, to ensure to be full of in annular seal space paraffin.
3rd, open lid and take excess paraffin away, put rubber sleeve, put into plug simultaneously, compress rubber sleeve, then with stamping machine, housing tip is carried out punch process with fixing plug, finally push rod is inserted, now wax formula temperature-sensitive package installs complete.
This wax formula temperature-sensitive bag, its housing red copper processes, and temperature zone surface configuration male and fomale(M&F), the built-in one section of cylinder in bottom, this configuration increases absorption heat area, improve temperature-sensitive bag sensitivity.In work process, the wax in temperature-sensitive bag is by carrying out heat transmission with outside, and expanding with heat and contract with cold of wax makes push rod elongation shorten, and controls cold and hot water inlets aperture.
Embodiment is not construed as the restriction invented, but any spiritual improvements introduced based on the present invention, all should within protection scope of the present invention.
