Thermostat and automobile engine cooling system provided with thermostat

Abstract

The invention discloses a thermostat and automobile engine cooling system provided with the thermostat, and belongs to the technical field of automobile engine cooling systems. A movable rod is arranged at one end of a thermostat body; an upper valve and a lower valve are fixedly installed on the surfaces of the two ends of the thermostat body; a large circulation pipeline is connected to one surface of the upper valve in a sealed mode; and an upper extrusion spring is connected to the other surface of the upper valve in a contact manner. According to a supporting base provided for the thermostat and automobile engine cooling system provided with the thermostat, rapid assembling and disassembling with a thermostat under the action of a mounting sleeve is achieved, the position on the surface of the thermostat can be freely adjusted, the assembling convenience is improved, and an upper limiting plate and a lower limiting plate have the function of moving up and down. The elastic force strength of the upper extrusion spring and a lower extrusion spring can be adjusted according to actual needs, the purchasing range of the springs is widened, and then the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile engine cooling systems, and more specifically, relates to a thermostat and an automobile engine cooling system provided with the thermostat. Background technique [0002] A thermostat is a valve that controls the flow path of coolant. It is an automatic temperature-regulating device that usually contains a temperature-sensing component that opens and closes the flow of air, gas, or liquid by thermal expansion or contraction. [0003] At present, in the process of using the thermostat, in order to ensure the tightness of the large and small circulation pipes in the engine cooling system, springs are usually used to squeeze the valves to improve the sealing effect, but the length of the springs used And the elastic strength greatly limits the scope of purchase of springs, thereby increasing the manufacturing cost, and most of the thermostat and the spring support frame are fixed together, which n...

Problems solved by technology

[0003] At present, in the process of using the thermostat, in order to ensure the tightness of the large and small circulation pipes in the engine cooling system, springs are usually used to squeeze the valves to improve the sealing effect, but the length of the springs used And the elastic strength greatly limits the scope of purchase of springs, thereby increasing the manufacturing cost, and most of the thermostat and the spring support frame are fixed together, which not only affects the installation, but also cannot fine-tune the support frame on the surface of the thermostat according to actual needs The location of the thermostat has caused certain restrictions on the production and assembly of the thermostat. Therefore, we have designed a thermostat and an automobile engine cooling system with the thermostat to solve the above problems.
