Description
Technical field
The present invention relates to a kind of electric-controlled type thermoregulator, be used for the loop control of explosive motor cooling water.
Background technique
Electric-controlled type thermoregulator application prospect is very extensive; The electric-controlled type thermoregulator mainly is made up of cavity, plug, lead-in wire, heater, sleeve, body, paraffin, rubber pipe, push rod, spring, valve, gland, caudal peduncle, auxiliary spring, auxiliary-valve at present; Machining hole on body; Through the hole heater is put into body, and be fixed on the body bottom; Heater extends body through lead-in wire and is connected with extraneous plug; Push rod is in bore portion cover rubber pipe in the body, and body exterior has sleeve, and whole heating unit is fixed on the cavity through sleeve.Switch on to heater through plug, heater heats paraffin lets the paraffin expanded by heating produce expansive force; Expansive force extruding rubber pipe, rubber pipe is pressure-ram again, impels push rod to produce thrust and motion; Push rod promotes the caudal peduncle motion, caudal peduncle interlock valve motion, thus realize valve opening.After thermostat outage, heater no longer adds heated paraffin, paraffin contractions of catching a cold, and expansive force disappears, the corresponding disappearance of push rod thrust, and spring reaction impels the valve returning movement on valve, thus the realization valve closing.This structure in use because heater is through behind machining hole on the body, putting into body, under the expansive force effect of paraffin high pressure, the phenomenon of heater and body contacting point leakage paraffin occurs; Because lead-in wire is embedded in the frequent extruding and the relexation of contact paraffin high pressure expansive force in the body, thereby cause the outage of fractureing property of lead-in wire.Because heater need put into body interior, in order to ensure the space requirement of paraffin body is strengthened, thereby body dimension is bigger, finally causes the thermoregulator volume excessive; Because heater is fixed on the body bottom; Thereby causing heating source is to be fixed on the body bottom can not move, and when adding heated paraffin, paraffin can only lean on the transmission of heat of nature slowly to be melted to the top from the bottom; Cause paraffin thawing speed slower, and make the sensitivity of thermoregulator low; Because body can not move, and can not directly connect valve, can only connect valve through accessory structures such as sleeves; Realize valve opening; Make that the additional structure partial volume is excessive around the body, when causing cooling water flow to cross thermoregulator, water resistance is big; Reduced the thermoregulator flow, the cooling effect of motor is poor.
Summary of the invention
The purpose of this invention is to provide a kind of electric-controlled type thermoregulator, overcome leakage wax that existing structure exists, the outage of fractureing property of lead-in wire, bulk volume is excessive, sensitivity is low, water resistance is big problem.
The objective of the invention is to realize as follows: a cavity that has two-port is arranged; Cavity one side is provided for connecting the plug of lead; Device has the pushing mechanism that is heated of valve and push rod on cavity; The be heated push rod outer end of pushing mechanism is fixed on the cavity, and push rod is in that end interior arrangement heater in the pushing mechanism that is heated, and has the lead that is connected with heater to pass the push rod endoporus and is connected to plug.
The structure of pushing mechanism of being heated is: a body that has blind hole is arranged; Be inserted with push rod in the endoporus of body, the push rod the other end stretches out in body exterior, is with the seal ring with the body open end sealing on the push rod; The body open end riveted joint fastens the gland of seal ring; Fill with paraffin by the body endoporus of seal ring sealing and the enclosed space between the push rod, the valve of riveted joint and the corresponding sealing of cavity port is with an end and is pressed in the spring on the valve on the body on gland; The other end of spring be supported on to body guiding and with the fixing support of cavity on, the body tail end is with the auxiliary-valve of auxiliary spring and axial limiting anticreep.
Give the energising of the heater in the push rod through plug, heater heats paraffin lets the paraffin expanded by heating produce expansive force; The direct pressure-ram of expansive force produces the thrust of the relative body of push rod; Because push rod and cavity are fixed, thrust promotes body and moves together with valve, thereby realizes valve opening.After thermoregulator outage, heater no longer adds heated paraffin, paraffin contractions of catching a cold, and expansive force disappears, the corresponding disappearance of push rod thrust, spring reaction impels the valve returning movement on valve, thus the realization valve closing.Through heater being put into the integrity that push rod keeps body, thereby eliminated under the effect of paraffin high pressure expansive force the problem of leaking wax from body.Heater is imbedded push rod inside and is not directly contacted paraffin, thereby has eliminated lead-in wire by the frequent extruding of paraffin high pressure expansive force and relexation and the problem of fractureing property outage.Because heater is in push rod, does not take the space of paraffin, need not to increase body structure, thereby has solved the excessive problem of thermoregulator volume.Because heater is inner at push rod, pushrod movement drives in the process of valve motion, and heating source moves with push rod, thereby can realize paraffin thawings of comprehensively being heated, and makes the heating paraffin conduction soon, and thermoregulator is highly sensitive.Because valve is directly to be connected with body, need not other additional structure, it is less to take up room, and water resistance is little, good cooling results.
The present invention imbeds push rod inside with heater, has eliminated heater lead by the environment of high-pressure extrusion, avoids the outage of fractureing property of lead-in wire; Guarantee the body complete structure, avoided the wax leakage; Body dimension does not increase, and body directly connects valve and eliminates other additional structure, thereby the volume that reduces thermoregulator has reduced water resistance; Because heater is put into push rod, is heated in the melting process at paraffin, heating source moves heating, and the heating paraffin conduction is fast, thereby has improved sensitivity.
