[0001] The utility model relates to an intercooler assembly in a turbocharged cooling system of an engine of a passenger car, a commercial vehicle and an engineering vehicle, and specifically to an intercooler automatic overflow valve, which has an automatic overflow function and ensures the airtightness of the intercooler assembly. Background Art
[0002] At present, the drainage function structural design of related drainage valve products in the industry are all metal spring-type opening and closing structures, which are complex in design and high in manufacturing cost. As the use time increases, the elastic performance of the spring decays and there is a risk of component failure. Utility Model Content
[0003] The purpose of the utility model invention is to provide an automatic overflow valve for an intercooler with low cost and stable performance, which is mainly used to solve the problem of condensate accumulation discharge of the intercooler assembly of a turbocharger of an automobile engine, to avoid condensate corrosion of the internal material of the heat exchange core of the intercooler assembly, to prevent condensate from freezing and damaging the product at low temperatures, to prevent the intercooler assembly from leaking due to corrosion, and at the same time to have a reliable airtightness function when the product is working.
[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: to provide an automatic overflow valve for an intercooler, including a valve housing, wherein a lightweight float and a sealing gasket are built in the valve housing, a self-locking drainage core and a dustproof cushion are sleeved on the bottom of the valve housing, and the valve housing is connected to the air chamber end of the intercooler through a thread.
[0005] The valve housing is a plastic valve housing.
[0006] The light float is in the shape of a plum blossom column, and the bottom sealing surface is a conical surface.
[0007] The overall density of the lightweight float is required to be lower than the density of water.
[0008] The outer diameter of the lightweight float is larger than the inner diameter of the air chamber hole, and the minimum distance of the float plum blossom groove is smaller than the inner diameter of the air chamber hole.
[0009] The valve housing and the intercooler air chamber are assembled by thread fastening and sealed by an O-type rubber sealing ring.
[0010] The self-locking drainage core at the bottom of the valve is provided with a cross-conical notch to achieve self-locking and drainage after assembly.
[0011] The end of the self-locking drainage core is a hemispherical groove, which is conducive to the assembly and anti-dropping of the dustproof rubber pad.

[0014] The outstanding beneficial results of the utility model are:
[0015] 1. When the condensed water in the intercooler flows downward into the valve housing, the lightweight float automatically floats up. The float will neither separate from the valve housing nor block the liquid above from continuing to flow into the valve housing. At the same time, the lower end smoothly opens the liquid release channel, and the liquid effectively overflows from the valve housing.
[0016] 2. When the car engine is started, the working pressure in the cooling system causes the float in the overflow valve to fit tightly with the rubber sealing gasket, achieving the product's airtight function and ensuring the normal operation of the engine.
[0017] 3. Simple structure, low manufacturing cost and stable performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical structure of the present invention is further described in detail below through the accompanying drawings and embodiments.
[0025] like Figure 1 As shown, the automatic overflow valve of the intercooler described in the utility model includes a valve housing 1, wherein the valve housing 1 has a lightweight float 3 and a sealing gasket 4 built in, a self-locking drainage core 5 and a dustproof cushion 6 sleeved on the bottom of the valve housing 1, and the valve housing 1 is connected to the end of the intercooler air chamber 7 through a thread.
[0026] The valve housing 1 is made of plastic.
[0027] The light float 3 is in the shape of a plum blossom column, and the bottom sealing surface is a conical surface.
[0028] The overall density of the lightweight float 3 is required to be lower than the density of water.
[0029] The outer diameter of the light float 3 is larger than the inner diameter of the air chamber hole, and the minimum distance of the plum blossom groove of the light float 3 is smaller than the inner diameter of the air chamber hole.
[0030] The valve housing 1 is assembled with the intercooler air chamber by threaded fastening and sealed by an O-type rubber ring 2 .
[0031] The self-locking drainage core 5 is provided with a cross-conical notch to achieve self-locking and drainage after assembly.
[0032] The end of the self-locking drainage core 5 is a hemispherical groove, which is conducive to the assembly and anti-falling of the dustproof cushion 6.
[0033] A rubber sealing gasket is arranged between the inner bottom surface of the valve housing and the light float.
[0034] The installation method of the intercooler automatic overflow valve is as follows: the self-locking drainage core 5 and the dustproof rubber cushion 6 are assembled first, and then assembled on the valve housing 1, and then the sealing gasket 4 and the light float 3 are respectively placed in the valve housing 1. Finally, the O-type rubber ring 2 is installed between the valve housing 1 and the air chamber of the intercooler, and the valve housing 1 and the air chamber are fastened by threaded connection.
[0035] The plum blossom groove channel of the lightweight float 3 is designed with a taper, and the upper groove is wider, which greatly increases the liquid inlet flow cross-sectional area.
[0036] The maximum outer diameter φD of the lightweight float 3 is larger than the inner hole φd of the air chamber of the intercooler to prevent the lightweight float 3 from escaping from the valve housing. The minimum distance W of the plum blossom groove of the float 3 must be smaller than the inner diameter φd of the air chamber hole to ensure smooth flow of accumulated water. Figure 1 shown.
[0037] like Figure 3 As shown, the intercooler air chamber mounting seat is provided with a shallow groove at the side of the groove for placing the O-type rubber ring 2. When the O-type rubber ring 2 is missing, it can be immediately discovered during the product online testing of the sealing performance, thereby preventing the false tight sealing between the valve housing 1 and the air chamber.
[0038] like Figure 4 As shown, the end of the self-locking drainage core 5 is a hemispherical groove, which is convenient for dust-proof rubber cushion assembly. The cross groove structure with chamfered corners on the upper end makes it easy to assemble on the valve housing 1 and then self-lock, and the assembly can be completed by manual operation.
[0039] The utility model has two working states, such as Figure 2As shown in the figure, one is the overflow state when the car is not started, the light float 3 floats up, opens the gap with the rubber sealing gasket 4, and releases the water in the valve. Figure 2 As shown by the curved arrow.
[0040] Another working state is, Figure 3 As shown, after the car is started, the pressure filled in the valve is normally 250kPa, and the lightweight float 3 moves down and is tightly pressed against the rubber sealing gasket 4 to ensure the airtight function of the intercooler and the normal operation of the car.
[0041] Working principle and process:
[0042] The intercooler automatic overflow valve described in the utility model is installed below the low level of the intercooler inner cavity, so that the condensed water in the intercooler inner cavity can be effectively and completely discharged. When the car is not started, the condensed water inside the intercooler assembly automatically flows into the overflow valve, the float floats up, and the accumulated water flows from top to bottom, through the self-locking drainage core at the bottom of the valve shell, and is discharged outside the valve shell. When the car is started, the engine turbocharges, and compressed air is introduced into the intercooler assembly. The float moves downward under the action of pressure and fits tightly with the rubber sealing gasket at the bottom of the valve shell cavity, achieving good sealing performance of the intercooler assembly and ensuring the normal operation of the car.
