Abstract
The utility model discloses an extrusion thermally sensitive element for a diesel locomotive. A thermal bag 4 filled with expansion agent 3 is put into a film bag 5, and a guide tube 1 and the thermal bag 4 are buckled and pressed to connect into integration. The utility model is characterized in that the pressing rod 2 connecting a top rod is directly arranged in the film bag 5. The utility model has the advantages of reliable performance, simple processing and high durability.
Description
The utility model is a temperature control component of internal combustion locomotive hydraulic system, and it produces the expansion force pushing mandril by the heating of the dilatant in its thermometer bulb and produces displacement, thus the control diesel engine oil.The temperature of water ensures normally carrying out of internal combustion locomotive hauling operation.
Existing expanssion type heat responsive element, see accompanying drawing 2: cylindrical shape thermometer bulb 15 is processed with thimble 17 along center line, fill dilatant 16 in it, and round rubber diaphragm 14 on the bedding, the conduit 12 of rubber plunger 13 and push rod 11 is installed, the one end is withheld on elastomer diaphragm 14, the dilatant 16 in the sealing thermometer bulb 15; Its other end is threaded on the heat-operated valve, is subjected to thermogenetic expansive force to order about push rod 11 and produces displacement, promotes the sliding valve movement of heat-operated valve.Because elastomer diaphragm 14 horizontal place mats, thereby under the thermal expansion force effect, the amplitude of its expansion is limited, causes the push rod 11 that promotes the heat-operated valve sliding valve movement not reach desired lift; And elastomer diaphragm 14 phenomenon such as tears, and its working life is short; Because thimble 17 is same bodies with thermometer bulb 16, it is processed with difficulty.
In order to overcome above-mentioned the deficiencies in the prior art, it is a kind of reasonable in design that the utility model provides, reliable performance, process simple and easy, long-lived internal combustion locomotive extruding type heat responsive element.
The measure that realizes above-mentioned purpose is: " U " type of Design and Machining rubber film bag, form the breathing system among pressure ram directly placed rubber film bag, and thermometer bulb is processed into cylindrical shape.
The utility model compared with prior art, whole element structure is simple. manufacture simplification. cost reduces. not only technical performance satisfies the internal combustion locomotive job requirements, and long service life.
Describe below in conjunction with accompanying drawing:
Accompanying drawing 1, the whole-cutaway view of internal combustion locomotive extruding type heat responsive element.
Accompanying drawing 1 has been described the overall structure of the utility model extruding type heat responsive element." U " type rubber film bag 5 places among the thermometer bulb 4 that fills with dilatant 3, and pressure ram 2 is connected and directly places on the push rod 6 among " U " type rubber film bag 5, forms the breathing system, conduit 1 and thermometer bulb 4 closely withhold be connected in aggregates." U " type rubber film bag 5 opening outer rims are bedded in thermometer bulb 4 in the form of a ring with sealed expander 3; Its tapered or hemisphere in bottom, when dilatant 3 expanded by heating, expansive force acts on film bag bottom, its vertical stress component impels pressure ram to rise, its horizontal component impels 5 compressions of film bag, also just forces pressure ram 2 constantly to rise along with dilatant 3 received heats constantly increase, and film bag 5 constantly compresses, thereby make push rod 6 realize the action of its rising, reach needed lift.When the temperature in element thermometer bulb 4 external worlds low, and dilatant 3 is when shrinking, push rod 2 is subjected to the effect of duct thermostat return spring (not shown) spring power and pressure ram 2 is moved down gradually, reverts to the origin-location, and " U " type rubber film bag 5 also returns to original state simultaneously.
Owing to the structure characteristic of " U " type rubber film bag self and be to be squeezed to force pressure ram 2 push rods 6 to rise, so film bag 5 is difficult for breaking, thermometer bulb 4 is difficult for breaking, this extruding type heat responsive element is durable in use. long service life, every technical performance satisfied temperature control valve sliding valve movement, effectively control the oil of diesel engine. coolant-temperature gage ensures normally carrying out of internal combustion locomotive hauling operation.
Claims (3)
1, the extruding type heat responsive element that is used for internal combustion locomotive, it fills with in the thermometer bulb 4 of dilatant 3 and is equipped with rubber film bag 5, conduit 1 is withheld with thermometer bulb 4 and linked into an integrated entity, and feature of the present utility model is: the pressure ram 2 reeve conduit 1 that links to each other with push rod 6 directly places " U " type rubber film bag 5.
2, extruding type heat responsive element according to claim 1 is characterized in that described " U " type rubber film bag 5 its opening outer rims in the form of a ring, its tapered or hemisphere in bottom.
3, extruding type heat responsive element according to claim 1 is characterized in that described thermometer bulb 4 is cylindrical shape.
