Abstract
The invention discloses a kind of induction thermometer bulb, this induction thermometer bulb is the control device of heating heat radiation constant temperature, be specially adapted on the high pressure steam conveyance conduit indoor temperature be made self-regulating induction thermometer bulb, this thermometer bulb includes housing (6), plunger (3) and push rod (1), be provided with temperature sense working medium (7) in the cavity volume of described housing (6), it is characterized in that being provided with a groove (5) at the middle part of housing (6), described groove (5) its underpart is induction working medium (7), it in the cavity volume on its top a plunger (3), described plunger (3) is connected as a single entity by pad (2) and push rod (1), on the interphase of described induction working medium (7) and plunger (3) diaphragm (4) is housed, described induction working medium (7) is paraffin wax, the described push rod (1) that is connected as a single entity with plunger (3) is slidingly matched in the hollow part of case cover (8), the breathing of described induction working medium (7) acts directly on the diaphragm (4), overcome the whole friction of push rod (1) in the sebific duct hole, improved sensitivity effectively, compared with prior art, have outstanding substantive distinguishing features and obvious improvement.
Description
Technical field
The present invention relates to a kind of thermostatic improvement invention, particularly be a kind of induction thermometer bulb that can A.T.C.
Background technology
In the prior art, the high pressure steam conveyance conduit of equipment such as boiler room leads to its flow of heating installation bag generally by the manual control valve, utilize the aperture size of valve to regulate the height that airshed is controlled temperature, not only troublesome poeration but also temperature also are difficult to control.Although occurred a glue pipe type sensing element at present, but the push rod of this sensing element is contained in the sebific duct hole when sebific duct is squeezed by the paraffin wax thermal expansion, push rod is squeezed moving displacement, push rod is moved upward, when paraffin wax is caught a cold contraction, push rod is by the spring force return, because push rod is whole contact in the sebific duct hole, the very big generation of friction lags behind, and adds paraffin wax itself and just has certain hysteresis, the stack of two hysteresises has seriously influenced the sensitivity of sensing element.
Summary of the invention
Problem in view of the known technology existence, purpose of the present invention aims to provide a kind of easy to operate, highly sensitive induction thermometer bulb is regulated the needs of indoor temperature automatically to satisfy heating system, the present invention finishes as follows: the induction thermometer bulb includes housing, plunger and push rod, be provided with temperature sense working medium in the described housing, it is characterized in that being provided with a groove at the middle part of housing, described groove bottom is induction working medium, its top is a plunger, described plunger is connected as a single entity by spring shim and push rod, on the interphase of described induction working medium and plunger diaphragm is housed, described induction working medium is the low temperature paraffin wax, described plunger and push rod are slidingly matched in the hollow part of case cover, because the breathing of induction working medium acts directly on the diaphragm, and the projection of diaphragm directly acts on plunger, eliminate whole friction, improved self-regulating sensitivity effectively.Compare with known technology, have outstanding substantive distinguishing features and obvious improvement.
Description of drawings
The present invention has following accompanying drawing:
Fig. 1 is a structural representation of the present invention.
Specific embodiment
Accompanying drawing has been represented structure of the present invention and embodiment, further describe each relevant details and principle of work thereof of embodiment below more in conjunction with the accompanying drawings, this induction thermometer bulb is the product supporting with thermostatic valve, include housing 6, plunger 3 and push rod 1, be provided with temperature sense working medium 7 in the cavity volume of described housing 6, the induction working medium 7 of present embodiment is the low temperature paraffin wax, the middle part of described housing 6 is provided with groove 5, described groove 5, be induction working medium 7 in the cavity volume that its underpart is, a rubber plunger 3 that is connected as a single entity by poly-Tetrafluoro spacer 2 and push rod 1 is housed in its top cavity volume, described induction working medium 7 is a diaphragm 4 with the interphase of plunger 3, the described push rod 1 that is connected as a single entity with plunger 3 is slidingly matched in the hollow part of case cover 8, the adjuster bar (not shown) of band controlling opening of valve is connected on described push rod 1 and the constant temperature flowing valve, becomes the self-regulating integral body of heating radiator.This induction thermometer bulb is adapted to the enrichment valve temperature detect switch (TDS) of motorcycle and automobile and the auxiliary products of thermostat equally.
After setting heating temperature, when temperature rises, low temperature paraffin wax melting dilation, pressure in the induction thermometer bulb rise, this pressure is with diaphragm 4 epireliefs, drive the push rod 1 that is connected as a single entity with plunger 3, drive on the adjuster bar again and move, reduce valve opening, the control steam flow, make temperature decline constant temperature, paraffin wax pressure when temperature descends in the induction thermometer bulb diminishes, and increases valve opening, strengthens steam flow, temperature rises, circulation is regulated so repeatedly, and temperature is controlled in the scope of setting effectively, reaches the constant temperature purpose.
Claims (2)
1, a kind of induction thermometer bulb, include housing (6), plunger (3) and push rod (1), be provided with temperature sense working medium (7) in the cavity volume of described housing (6), it is characterized in that being provided with a groove (5) at the middle part of housing (6), described groove (5) its underpart is induction working medium (7), its top is a plunger (3), and described plunger (3) is connected as a single entity by pad (2) and push rod (1), on the interphase of described induction working medium (7) and plunger (3) diaphragm (4) is housed.
