Background technique
Diesel engine is widely used in truck conspicuity marking with the characteristics of its high-power output.Cooling system can be kept motor and all can work under suitable temperature under the various operating modes, and most of motor all adopts water-cooling pattern.If yet in the constituent of sealing, exist air or steam bubble can reduce cooling effect.Because in the system of closed circulation, air can hinder water cycle as aeroembolism, if having air also can cause corrosion of metal in the engine water-cooling system simultaneously, therefore when engine-cooling system is worked, the gas that produces must be discharged.The discharging of engine cooling water system hollow gas is at present mainly discharged by opening the thermostat air relief cock, or in major cycle all gas is drained into the swelling water tank discharging, and latter's exhaust period is longer.If before therefore the venting Cezanne of thermostat was not opened, the gas that produces in the motor can't in time be discharged.The present invention connects thermostat, water tank, swelling water tank by Wen's three-way device, even do not open at thermostat, in-engine gas also can be discharged timely and effectively, can reduce the pressure of engine water circulation time cooling system.
Summary of the invention
The objective of the invention is, a kind of device that can get rid of gas in the engine-cooling system timely and effectively is provided.
Below in conjunction with accompanying drawing structure of the present invention and working principle are described.The engine cooling water system and device that has the automatic vent function has: motor, thermostat, swelling water tank, water tank and water pump etc.Its technological scheme key is to be set to Wen's three-way pipe between thermostat, swelling water tank and water tank.Connect in the design concrete: the thermostat connecting tube is connected to Wen's three-way pipe inlet tube; The swelling water tank connecting tube is connected to Wen's three-way pipe outer pipe; Water tank connecting pipe is connected to the bypass (as Fig. 1) of Wen's three-way pipe.Engine cooling circulating water constitutes circulation by thermostat, water tank and water pump successively, and the swelling water tank water outlet is connected to water tank, and radiator drain and thermostat distributed water pipe are connected to water pump.Constitute complete cooling water circulation thus.The inlet tube of Wen's three-way pipe and outer pipe constitute Venturi tube structure (as Fig. 2) in Wen's three-way pipe cavity.Its working principle is: when does not open as yet the cooling water main passage of thermostat, if the air that exists in the engine cooling water enters the inlet tube of Wen's three-way pipe.This inlet tube is a structure of reducing, and when air-water mixture passed through this reducer pipe, the pressure of fluid will descend, and makes flow rate of fluid increase thus; Because the inlet tube and the outer pipe of Wen's three-way pipe are positioned at same axis, when fluid enters the entry end of outer pipe, the position that borders at inlet tube and outer pipe can form certain degree of vacuum, and air pressure is relatively low near the throat of outer pipe, thereby produce suction-operated and cause accelerating the flowing velocity of fluid, therefore can effectively the gas in the motor, in the water tank be discharged to swelling water tank.After open thermostat cooling water main passage, in the cooling water recirculation system that thermostat, water tank, water pump and respective line are formed, the steam, the air in the cooling water and steam in the water tank or the air that produce in the motor will drain into swelling water tank by the bypass tube in Wen's three-way valve.
