Thermostat

Abstract

The invention relates to a thermolator, wherein, a cylinder-shaped main valve seat has an open end connected with a discal valve plate through connecting plates which are alternately arranged; a tubular main valve is positioned between the main valve seat and the valve plate; the outer tube wall of the main valve and the inner wall of the main valve seat form a sliding fit; the main valve and a valve rod are fixedly connected; a rod body of the valve rod passes through the valve plate and has a segment positioned outside the valve plate; the center line of the valve rod, the center line of the main valve and the center line of the main valve seat are superposed; an inner cavity of the main valve is communicated with an inner cavity of the main valve seat and is communicated with the conduction part around the valve rod in the center of the valve plate; the rod body of the valve rod between the valve plate and the main valve is provided with a memory spring; the valve rod outside the valve plate is provided with a release spring; and one end of the main valve and the plate surface around the conduction part on the valve plate form a on-off fitting state for the main valve in a contact position and a separate position. The thermolator maintains smooth state during working, uses a heat sensitive spring made of shape memory alloy, and has the advantages of firmness and durability,low cost, simple structure and long service life.

Description

technical field [0001] The invention relates to a valve body, specifically a thermostat for the cooling system of an automobile engine, also known as a thermostat. Background technique [0002] The thermostat, also known as the thermostat, is a component of the car engine cooling system. Its function is to adjust the temperature of the engine circulating cooling water to ensure that the internal combustion engine always works in the best state. [0003] In the current thermostat, when the thermostat valve is not opened, the thermostat valve is impacted by unilateral water pressure. Therefore, when the thermostat is opened, it needs to overcome the strong water pressure, and when the thermostat is opened, When the water pressure is released instantly, the thermostat valve may vibrate to a certain extent. In this process, it will cause fluctuations in water temperature, and even vibration, which will seriously affect the service life of the thermostat. Contents of the invent...

[0003] In the current thermostat, when the thermostat valve is not opened, the thermostat valve is impacted by unilateral water pressure. Therefore, when the thermostat is opened, it needs to overcome the strong water pressure, and when the thermostat is opened, When the water pressure is released instantly, the valve of the thermostat may vibrate to a certain extent. In this process, the water temperature will fluctuate and even cause vibrations, which will seriously affect the service life of the thermostat.
