Abstract
The utility model relates to a thermostat sealing ring, which comprises an annular sealing ring substrate, sealing ribs, an abdicating groove, a thermostat installation groove and a limiting boss, wherein the sealing ribs are arranged on the upper and lower end faces of the sealing ring substrate; the thermostat installation groove is arranged around the inner side of the sealing ring substrate; the abdicating groove is arranged at the inner side of the sealing ring substrate and corresponds to a thermostat exhaust valve in position; and the limiting boss is arranged at the outer side of the sealing ring substrate and is matched with a limiting groove in a thermostat base. The thermostat sealing ring can ensure that a thermostat is installed in a correct angle and can also prevent the thermostat exhaust valve during being opened from interfering with the sealing ring, and therefore thermostat exhaust is not influenced.
Description
Technical field
The utility model relates to petrol engine thermostat seal arrangement, particularly a kind of novel thermostat seal ring.
Background technique
Thermostat is the key components and parts of engine-cooling system, and the thermostat seal ring has direct influence to the performance of thermostat effect.If poorly sealed, thermostat causes the short circle in the engine cooling circulation to quit work with ineffective, can only be by full circulation operation.
Different vehicle thermostats are put the angle difference, especially put motor for vertical, and the outlet valve on the thermostat must be positioned at the top, when therefore thermostat being installed setting angle is had strict requirement.Common thermostat seal ring can't guarantee that thermostat is with correct angle installation at present, all can cause can't normal exhaust if the thermostat setting angle has deviation or outlet valve and seal ring to interfere, the cooling liquid flow resistance can increase, and local water temperature uprises, thereby influences the cooling effect of whole motor.Therefore developing a kind of thermostat that can guarantee can be exactly current problem demanding prompt solution with the thermostat seal ring of correct angle installation.
The model utility content
Can't guarantee that for solving existing thermostat seal ring thermostat is with correct angle installation, the utility model proposes a kind of thermostat seal ring that has positive stop lug boss and slot to make way, both can guarantee that thermostat was with correct angle installation, in the time of can preventing again that the thermostat outlet valve from opening and seal ring interfere, thereby guarantee that the thermostat exhaust is unaffected.
Embodiment of the present utility model is:
A kind of thermostat seal ring, comprise the O-ring seal matrix, sealed muscle, slot to make way, thermostat mounting groove and positive stop lug boss, described sealed muscle is arranged on the upper and lower end face of described seal ring matrix, described thermostat mounting groove is around being arranged on seal ring matrix inboard, and described slot to make way is arranged on seal ring matrix inboard, and is corresponding with the position of thermostat outlet valve, described positive stop lug boss is arranged on the seal ring matrix outside, matches with restraining groove on the thermostat base.
Described sealed muscle is two circles, and respectively around on the upper and lower end face that is arranged at described seal ring matrix, the cross section of described sealed muscle is trapezoidal.
Described thermostat mounting groove is circular groove, and the cross section is the rectangle of opening.
Described positive stop lug boss and slot to make way are 180 ° of distributions in a circumferential direction.
The beneficial effects of the utility model are:
1) described positive stop lug boss can play position-limiting action, can install with correct angle to guarantee thermostat.
2) described slot to make way, corresponding with the position of thermostat outlet valve during installation, in the time of preventing that the thermostat outlet valve from opening and seal ring interfere, thereby guarantee that the thermostat exhaust is unaffected.
3) described thermostat mounting groove is circular groove, and the cross section is the rectangle of opening, and its upper and lower surface is close to the thermostat valve seat, owing to there is bigger friction factor, guarantees can not rotate freely relative to seal ring in the thermostat working procedure.
4) described sealed muscle is symmetrically distributed in the upper and lower end face of seal ring matrix, both can guarantee fill factor and the compressibility of seal ring simultaneously, prevents that the sealing ring material interior tissue from being destroyed, and can guarantee good sealing effect again, can also save material.
5) its cross section of described sealed muscle is trapezoidal simultaneously, and when being squeezed, this shape is conducive to material extends to the space, both sides, prevents that the sealed muscle material from being damaged by pressure.

Fig. 2 is thermostat seal ring schematic cross-section of the present utility model;
Fig. 3 is the thermostat structural representation behind the installation thermostat seal ring of the present utility model;
Fig. 4 is the thermostat base structural representation.
Embodiment
As shown in Figure 1, 2, thermostat seal ring of the present utility model comprises O-ring seal matrix 1, positive stop lug boss 2, sealed muscle 3, thermostat mounting groove 4 and slot to make way 5.Two circle sealed muscles 3 are looped around respectively on the upper and lower end face of described seal ring matrix 1, and its cross section is trapezoidal; Thermostat mounting groove 4 is circular groove around the middle inside that is arranged on seal ring matrix 1, and its cross section is the rectangle of opening; Described slot to make way 5 is arranged on the inboard of seal ring matrix 1, and described positive stop lug boss 2 is arranged on the outside of seal ring matrix 1, and described positive stop lug boss and slot to make way are 180 ° of distributions in a circumferential direction.
As shown in Figure 3, owing to need to reduce the flow resistance after thermostat is opened, increase thermostatic valve 8 circulation diameters, outlet valve 6 on the thermostat valve seat 9 outwards must be arranged by radial direction as far as possible, just might interfere with seal ring when thermostat outlet valve 6 is opened at this moment, therefore the slot to make way of offering in the inboard of seal ring matrix 15 can guarantee the smooth opening of thermostat outlet valve 6, makes its exhaust unaffected.
Shown in Fig. 3,4, positive stop lug boss 2 is stuck in the restraining groove 7 on the thermostat base, thermostat just can be installed on the thermostat base with correct angle.Thermostat is put into seal ring mounting groove 4, and make the position of slot to make way 5 corresponding with outlet valve 6.Because have bigger friction factor, thermostat can not freely rotate relative to seal ring.When the seal ring that has assembled thermostat was installed in thermostat base and thermostat housing centre, thermostat seal ring upper and lower end face was squeezed, and when the seal ring compressibility met the demands, fill factor will be greater than 100%, and the sealing ring material interior tissue can be destroyed.Therefore sealing ring material must be removed a part, just form described sealed muscle 3.Material can extend to spatial position, described sealed muscle 3 both sides when seal ring was extruded, thereby can guarantee compressibility and the fill factor of material simultaneously, avoided the sealing ring material interior tissue to be destroyed.Thermostat base, thermostat housing sealing surface are machine and add the surface simultaneously, and its planeness is better, and the seal ring upper and lower end face seals with sealed muscle 3, can guarantee good sealing effect, can also save material.
