Thermolator seat

Abstract

The invention discloses a thermolator seat. The thermolator seat comprises a thermolator seat body; a thermolator is installed on the thermolator seat body; the thermolator seat body is fixedly provided with a thermolator seat sealing surface; the part, corresponding to the thermolator seat sealing surface, of the thermolator seat body is fixedly provided with a thermolator seat step surface; a cast sand core is installed on the thermolator seat body; the part, corresponding to the thermolator seat body, of the cast sand core is fixedly provided with a cast sand core thin wall region; the thermolator seat sealing surface is fixedly provided with a threaded hole; the threaded hole is connected with a cushion block; and the part, corresponding to the thermolator seat step surface, of the cushion block is provided with a cushion block sealing surface. Thereby, the thermolator seat disclosed by the invention is simple and reasonable in structure, reduces the fault of breakage generated inassembly of the cast sand core, increases the rate of finished products of blank casting of the thermolator seat, and also lowers the cost of the components of the thermolator seat.

Description

technical field [0001] The present invention relates to the technical field of engine parts, in particular to a thermostat seat. Background technique [0002] As the core component of the internal combustion engine cooling system, the thermostat has an important impact on the fuel economy and emission performance of the internal combustion engine while ensuring the normal operation of the internal combustion engine. Its development is highly valued by the automotive industry. The thermostat, also known as the thermostat, is a valve that controls the flow path of the coolant. As an automatic temperature control device, it usually contains a temperature sensing component, which opens or closes the flow of air, gas or liquid through expansion or contraction. Its function is to automatically adjust the amount of water entering the radiator according to the temperature of the engine cooling water, and change the water circulation range to adjust the heat dissipation capacity of ...

AI Technical Summary

Problems solved by technology

However, it is often necessary to install several thermostats in high-power engines, and the inner cavity structure of the thermostat seat is complex. When the integral design is adopted, the cast aluminum material cannot be used for high-pressure casting, and only ordinary casting processes can be used.

Limited by the lift of the thermostat, the local space in the inner cavity of the thermostat seat is very small, so the local thickness of the sand core is required to be very small, and the part is easy to break when the sand core is assembled or poured, which is prone to casting defects and the scrap rate high, high cost
