Abstract

The invention discloses a lower shell of a thermostat. The lower shell comprises a shell body, wherein the shell body is provided with a first connecting flange, and the first connecting flange is provided with a liquid inlet hole; the end face of the first connecting flange in the forward direction is provided with an annular sealing groove, the first connecting flange is further provided with anotch communicated with the annular sealing groove, and the first connecting flange is further provided with a first mounting hole and a limiting counter bore; the side wall, close to the first connecting flange, of the shell body is provided with a by-pass pipeline, the by-pass pipeline is provided with a connector, and the connector is provided with a sealing ring groove; the shell body is further provided with a second connecting flange used for being connected to an upper shell, the second connecting flange is provided with a liquid outlet hole, and a stop groove is formed in the top of the position, close to the liquid outlet hole, of the second connecting flange. The invention also discloses machining method of the lower shell of the thermostat. The lower shell of the thermostat andthe machining method of the lower shell have the advantages that the structure is simple, a sealing structure is arranged on the connecting surface, the sealing stability is improved, and the productis conveniently and accurately positioned during machining.

Description

technical field [0001] The invention relates to the technical field of automobile engine thermostats, in particular to a thermostat lower shell and a processing method thereof. Background technique [0002] The thermostat (thermostat) automatically adjusts the amount of water entering the radiator according to the temperature of the cooling water, and changes the water circulation range to adjust the heat dissipation capacity of the cooling system to ensure that the engine works within a suitable temperature range. The thermostat must be kept in good technical condition, otherwise it will seriously affect the normal operation of the engine. [0003] The thermostat assembly is mainly used to adjust the temperature of the automobile engine. The traditional thermostat assembly is mainly composed of the shell and the thermostat inside the shell. Its performance directly affects the cooling performance of the cooling system. . At present, there are certain problems in the exist...
