Abstract
The invention discloses an upper shell of a thermostat. The upper shell comprises a body, an installation hole and an inner cavity capable of containing the thermostat are formed in the body, a groove capable of being matched with the conical side wall of the thermostat is formed in the bottom end face of the body, and the groove extends to the side wall of the inner cavity, wherein the groove is designed into a cylindrical groove or a conical groove. Meanwhile, the body is integrally formed and is an aluminum alloy casting. The groove of the upper shell of the thermostat is mutually matched with the conical side face of the thermostat, meanwhile, a top valve of the thermostat can be matched with the bottom end face of the upper shell of the thermostat through an elastic gasket, matching tightness of the thermostat and the upper shell of the thermostat is improved, leakage of cooling water at the matching position is prevented, and the service life of the thermostat is prolonged indirectly. According to the integrally formed body structure, the manufacturing processes of the upper shell of the thermostat are reduced, the production efficiency is improved, the upper shell of the thermostat can be produced in a mass mode, and the cost is saved.
Description
Technical field
The present invention relates to a kind of assembly of thermostat, particularly a kind of thermostat upper casing.
Background technique
Thermostat is widely used on vehicular engine, is automatically to regulate according to the height of cooling water temperature the water yield that enters radiator, changes the range of DO of water, and to regulate the heat dissipation potential of cooling system, assurance motor is worked in suitable temperature range.Thermostat must keep good state of the art, otherwise can have a strong impact on the normal work of motor; The thermostat of existing use is mostly just by coordinating to carry out the folding of cooling system between thermostat upper casing bottom end and thermostat overhead-valve, because thermostat often opens and closes in the time working, between thermostat upper casing and thermostat overhead-valve, cooperation place cooling water easily leaks, easily directly cause the inefficacy of thermostat, and add that thermostat replacing is frequent, indirectly shortened the working life of thermostat.
Summary of the invention
The object of the invention is to overcome existing thermostat upper casing in prior art coordinates tight not with thermostat, easily cause the leakage of cooling water, affect the deficiency of the use of thermostat, a kind of thermostat upper casing is provided, this thermostat upper casing simplicity of design, can coordinate with thermostat the working life of tightly, indirectly improving thermostat.
In order to realize foregoing invention object, the invention provides following technological scheme:
A kind of thermostat upper casing, a kind of thermostat upper casing, comprises body, and described body is provided with mounting hole, and can hold the inner chamber of thermostat, and the bottom end of described body is provided with the groove that can match with thermostat cone flank wall, and described groove extends to described intracavity sidewall.
Preferably, described groove is cylinder shape groove, coaxial with chamber body, and with described chamber body sidewall arc transition.
Preferably, described groove is frustoconic shape groove, and its further groove lower end diameter of a circle crossing with described bottom end is larger, groove upper end and described chamber body sidewall arc transition.
Preferably, described thermostat upper casing bottom end cooperatively interacts by elastic washer and thermostat overhead-valve.
Preferably, described body is formed in one, and is aluminium alloy castings.
Compare with machining, this body by integral forming, with aluminium alloy castings, has reduced production process, easy to manufacture, can be mass, and enhances productivity, cost-saving.
compared with prior art, beneficial effect of the present invention:
A kind of thermostat upper casing of the present invention, by offering groove at thermostat bottom end, and extend to thermostat intracavity sidewall, can cooperatively interact by thermostat cone flank wall and thermostat upper casing groove, by elastic washer, thermostat overhead-valve and thermostat upper casing bottom end are cooperatively interacted simultaneously, thereby improve the tightness that thermostat coordinates with thermostat upper casing, prevent that thermostat from often opening and closing the leakage that causes cooperation place cooling water between thermostat upper casing and thermostat, the working life of indirectly having improved thermostat in the time of work; This thermostat upper casing is one-body molded by aluminium alloy castings simultaneously, has reduced warm device upper casing production process, has improved manufacturing efficiency, can manufacture, and has saved cost, easy accessibility.
Accompanying drawing explanation:

Fig. 2 is A-A sectional structure schematic diagram in Fig. 1.
Fig. 3 is that a kind of thermostat upper casing of the present invention coordinates schematic diagram (wherein only thermostat upper casing having been carried out to section as shown in Figure 2 shows) with thermostat.
Mark in figure:
1, body, 2, mounting hole, 3, inner chamber, 4, intracavity sidewall, 5, bottom end, 6, groove, 7, elastic washer, 8, thermostat overhead-valve, 9, thermostat cone flank wall.
Embodiment
Below in conjunction with test example and embodiment, the present invention is described in further detail.But this should be interpreted as to the scope of the above-mentioned theme of the present invention only limits to following embodiment, all technology realizing based on content of the present invention all belong to scope of the present invention.
As Figure 1-3, a kind of thermostat upper casing, comprises body 1, described body 1 is provided with mounting hole 2, and can hold the inner chamber 3 of thermostat, and the bottom end 5 of described body 1 is provided with the groove 6 that can match with thermostat cone flank wall 9, and described groove 6 extends to described intracavity sidewall 4.
The present embodiment further groove 6 is designed to cylinder shape groove 6, and this cylinder shape groove 6 is coaxial with chamber body 3, and with chamber body sidewall 4 arc transition; Thermostat upper casing bottom end 5 cooperatively interacts by elastic washer 7 and thermostat overhead-valve 8 simultaneously.As shown in Figure 2, thermostat cone flank wall 9 can cooperatively interact with thermostat upper casing groove 6 like this, thermostat overhead-valve 8 and thermostat upper casing bottom end 5 can be cooperatively interacted by elastic washer 7 simultaneously, dual cooperation has improved the coordinate tightness of thermostat with thermostat upper casing, prevent that thermostat from often opening and closing the leakage that causes cooperation place cooling water between thermostat upper casing and thermostat, the working life of indirectly having improved thermostat in the time of work.
When groove 6 is for being designed to frustoconic shape groove 6, groove 6 lower ends are larger with the crossing diameter of a circle of described bottom end 5, groove 6 upper ends and chamber body sidewall 4 arc transition, and thermostat upper casing and the cooperation of thermostat also can reach same effect.
This thermostat upper casing is integrated in addition, and is aluminium alloy castings, compares machining, has greatly reduced the production process of warm device upper casing, has improved manufacturing efficiency, can manufacture, and has saved cost, easy accessibility.
