Abstract
The utility model relates to a sealing structure for a thermosistor body cover head part, a seal ring is arranged between the body cover and a push rod, a groove is arranged above the seal ring along the axial body cover, and a gasket arranged parallel to the seal ring along the axial direction is arranged between the groove and the push rod. In the utility model, as the sealing structure of the seal ring and the gasket is additionally arranged between the inner through hole of the body cover head part and the push rod to seal the body cover and the push rod, so that the push rod is good in sealing while moving in a sensor, cooling liquid can not enter the sensor through a gap between the push rod and the body cover, lubricating grease and temperature-sensing paraffin in the sensor can not flow out from the gap between the sealing structure and the body cover, influence on the performance of the thermosistor is avoided, and the product performance is safer and more reliable. The sealing structure has good sealing effect, a simple structure, low production cost and practicability.
Description
Technical field
The utility model belongs to vehicle and uses the thermoregulator technical field, specifically is meant a kind of thermoregulator body cap head seal structure.
Background technique
Known common thermoregulator is made up of push rod, valve seat, valve, support, spring and inductor etc. at present.Its working principle is: just open temperature when above when engine temperature is elevated to, the inductor pushrod movement also drives valve opening, makes the part cooling liquid get into the major cycle heat radiation.Along with engine temperature continues to raise, valve continues to open, and coolant rate strengthens, and heat radiation is strengthened, and when main valve reached full-gear, it is maximum that the flow of major cycle reaches, and the cooling system heat dissipation potential reaches capacity, and engine temperature begins to descend.Along with the decline of engine temperature, the inductor push rod begins to fall after rise under the effect of big spring, and main valve is closed gradually; Coolant rate through major cycle is also along with reducing, and the motor cooling rate is slack-off, when engine temperature continues to reduce; Push rod continues to fall after rise, closes fully until main valve, through the dynamic adjustments of a period of time; Engine temperature is fluctuation up and down in certain temperature range, can be not too high can be not low excessively yet, thereby play the purpose of protection motor.
But traditional thermoregulator body cap structure is as shown in Figure 1, and wherein the inner via hole that links to each other with push rod of body cap is a unthreaded hole.When automobile starting, the engine water pump startup provides antifreeze liquid circulation cooling power.But antifreeze liquid under the water-aspirator pressure effect, gets into sebific duct through the gap between push rod and the body cap for a long time, influences the thermoregulator performance, life of product can't be guaranteed, thereby can't meet customer need.
Summary of the invention
The purpose of the utility model is according to above-mentioned deficiency a kind of thermoregulator body cap head seal structure to be provided, and can make good seal between body cap and the push rod, and the thermoregulator performance is more stable, and the life-span is longer.
The technological scheme of the utility model is following: a kind of thermoregulator body cap head seal structure; It is characterized in that: between body cap and push rod, be provided with seal ring; Seal ring top body cap vertically is provided with groove, is provided with vertically the pad that is arranged side by side with seal ring between groove and the push rod.
Said seal ring is the O RunddichtringO.
The utility model comes seal body lid and push rod through the sealing configuration of between the inner via hole of body cap head and push rod, setting up seal ring and pad; Good seal when push rod is moved in inductor; It is inner to make cooling liquid not get into inductor through the gap between push rod and the body cap; Lubricating grease that inductor is inner and temperature-sensitive wax can not flow out through the slit of sealing configuration and body cap yet, influence the performance of thermoregulator, and product performance are more safe and reliable.The utility model good sealing effect, simple in structure, low cost of manufacture has practicability.
Description of drawings
Fig. 1 is traditional thermoregulator sensor structure schematic representation;
Fig. 2 is the thermoregulator sensor structure schematic representation that has the utility model sealing configuration;
1. inductor, 2. push rod, 3. pad, 4.O RunddichtringO, 5. body cap.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing:
As shown in Figure 2, between body cap 5 and push rod 2, be provided with O RunddichtringO 4, the top of O RunddichtringO 4 body cap 5 vertically is provided with groove, is provided with vertically the pad 3 that is arranged side by side with the O RunddichtringO between groove and the push rod 2.
In inductor 1, between the inner via hole and push rod 2 of body cap 5 heads, form by a pad 3 and an O RunddichtringO 4.Such sealing configuration can seal body lid 5 and push rod 2, freezing liquid can not get into sebific duct through the gap between push rod 2 and the body cap 5, lubricating grease and temperature-sensitive wax also can be through the slit outflows of sealing configuration and body cap, thereby influence the performance of thermoregulator.
The utility model good sealing effect, simple in structure, low cost of manufacture has practicability.
Claims (2)
1. thermoregulator body cap head seal structure is characterized in that: between body cap and push rod, be provided with seal ring, seal ring top body cap vertically is provided with groove, is provided with vertically the pad that is arranged side by side with seal ring between groove and the push rod.
2. according to the said thermoregulator body cap of claim 1 head seal structure, it is characterized in that: said seal ring is the O RunddichtringO.
