Description
Technical field
The invention belongs to petrol engine water channel cycle art, specifically, particularly thermostat base.
Background technique
Thermostat base is the vitals of the petrol engine water channel circulatory system.The structure of existing thermostat base is as shown in Figure 3, has pedestal 1, and the top of this pedestal 1 is provided with two air-conditioning HVAC pipes 2,2 ' that are parallel to each other, and the bottom surface of the axis of air-conditioning HVAC pipe and pedestal 1 is perpendicular.Be provided with two closure HVAC pipes in the side of pedestal 1, the axis of this closure HVAC pipe and the bottom surface of pedestal 1 parallel.Have cooling-water temperature sensor installation base 3 between said air-conditioning HVAC pipe and the closure HVAC pipe, this cooling-water temperature sensor installation base 3 is in tilted layout with respect to the bottom surface of pedestal 1.The deficiency of above conventional construction is:
1, pedestal adopts metal material; And pedestal and air-conditioning HVAC pipe and closure HVAC pipe are non-integrally formed, and each HVAC pipe is processed separately by another kind of metallic material, is pressed into pedestal again; Need secondary or repeatedly processing in the cooperation; Fitting surface processing technology to joint between pedestal and the HVAC pipe is had relatively high expectations, complex process, and manufacturing efficiency is low;
2, thermostat base adopts all-metal material to process; Weight is big, cost is high; And sealing reliability is relatively poor between pedestal and each the HVAC pipe, and easy the leakage need be carried out the tightness detection to all over products for just preventing to reveal; Increase the cost of producing special detection tool like this, increased the operation of testing product;
3, thermostat base is installed on the below of storage battery usually, because the bottom surface of the axis of air-conditioning HVAC pipe and pedestal is perpendicular, makes that the overall height dimension of thermostat base is bigger; Reach about 87mm, the mouth of pipe of air-conditioning HVAC pipe is too near apart from storage battery like this, is not easy to thermostat base and installs; The metal tube of HVAC Guan Weizhi is difficult for need doing deformation process with the layout of car load, because this metal HVAC pipe diameter is big simultaneously; If the bent angle radius is little, form fold easily, break, its bending technique property is bad;
4, the smoothness of thermostat base internal surface is relatively poor, and the resistance of flow of fluid is bigger.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of and is easy to process, can effectively avoid the thermostat base that leaks.
Technological scheme of the present invention is following: a kind of thermostat base of gasoline engine; Comprise pedestal, the first air-conditioning HVAC pipe, the second air-conditioning HVAC pipe, cooling-water temperature sensor installation base, first segment valve HVAC pipe and the second closure HVAC pipe; Wherein the top of pedestal is provided with the first air-conditioning HVAC pipe and the second air-conditioning HVAC pipe; The top of present body side surface is provided with the cooling-water temperature sensor installation base; The bottom of pedestal side is provided with the first segment valve HVAC pipe and the second closure HVAC pipe; And the axis of closure HVAC pipe and the bottom surface of pedestal parallel, and its key is: said pedestal, air-conditioning HVAC pipe, cooling-water temperature sensor installation base and valve HVAC pipe pass through injection molding.
The present invention adopts identical plastic material through the disposable integral molding and forming pedestal, air-conditioning HVAC pipe, cooling-water temperature sensor installation base and valve HVAC pipe; Not only operation is simple, and manufacturing efficiency is faster, and is in light weight; Cost of production is low; And the good reliability that seals between HVAC pipe and the pedestal, leakage problem can not take place, practiced thrift the late detection cost.Simultaneously, the thermostat base internal surface is smooth, and the resistance of flow of fluid is little.
The said first air-conditioning HVAC pipe and the second air-conditioning HVAC pipe are formed by horizontal segment and arc section, and horizontal segment links to each other with the top of pedestal through arc section; The horizontal segment of the said first air-conditioning HVAC pipe be positioned at first segment valve HVAC pipe directly over, both parallel; The horizontal segment of the second air-conditioning HVAC pipe be positioned at the second closure HVAC pipe directly over, both also parallel.Above structure has shortened the whole height of thermostat base on the one hand, and the height of thermostat base is reduced to about 80mm, and this spline structure is compact more, and air-conditioning HVAC pipe is bigger apart from the spacing of storage battery, can make things convenient for thermostat base to install; On the other hand, the mouth of pipe of two air-conditioning HVAC pipes respectively with the mouth of pipe of two closure HVAC pipes in the same way, help pipeline and connect, be convenient to the pipeline cabling.
Have angle a between the horizontal segment of the horizontal segment of the said first air-conditioning HVAC pipe and the second air-conditioning HVAC pipe, the size of this a is 25～35 °.The horizontal segment of the horizontal segment of the first air-conditioning HVAC pipe and the second air-conditioning HVAC pipe several angle that staggers can be avoided the installation journal stirrup on the pedestal is blocked, and helps fast assembling-disassembling.
Said cooling-water temperature sensor installation base is between the horizontal segment and first segment valve HVAC pipe of the first air-conditioning HVAC pipe; And be horizontally disposed with respect to the bottom surface of pedestal, the mouth of pipe of the aperture of the mounting hole of offering on this cooling-water temperature sensor installation base and the first air-conditioning HVAC pipe and the mouth of pipe of first segment valve HVAC pipe are towards identical direction.It is more convenient that above structure is installed cooling-water temperature sensor on the one hand, is easy to the demoulding on the other hand, can simplified processing process, further enhance productivity.
The root of the said first segment valve HVAC pipe and the second closure HVAC pipe is provided with the countersinking section, and the stub end of this countersinking section links to each other with pedestal.The effect that countersinking Duan Jiqi gains in strength more helps sealing simultaneously when being inserted in external pipeline.
Beneficial effect: the present invention adopts the injection moulding global formation, has both simplified operation, has improved manufacturing efficiency, has reduced weight and cost of production again, has effectively avoided leakage, and mounting arrangements is simpler, convenient; Compare with traditional metal structure, cost of the present invention is lower by 10% than metalwork, and mobile damping is than metalwork low 5%.
