Description

Automatic water drain valve for intercooler air chamber

Technical Field

The utility model relates to an intercooler field especially relates to intercooler air chamber field, specifically indicates an automatic valve that drains for intercooler air chamber.

Background

The intercooler is an important component of a diesel engine supercharging system, air entering the cylinder is cooled between the outlet of the turbocharger and the air inlet pipe, the intercooler is cooled by air or water in the heat radiator, and the heat of the air is dissipated to the atmosphere through cooling. The temperature of the intake air can be raised to more than 150 ℃ after the intake air is pressurized, the high-temperature air can be cooled to about 50 ℃ through the cooling effect of the intercooler. In the process, water vapor in the air can be condensed to form liquid water, and particularly in rainy days or environments with high air humidity, a large amount of condensed water can be formed in the intercooler. When the diesel engine operates, partial condensed water can be changed into vapor and is discharged together with waste gas after entering the cylinder along with air inlet, but the condensed water can flow back to the bottom of the intercooler after the engine is shut down, a large amount of condensed water enters the engine combustion chamber along with air inlet during next operation, on one hand, the engine can be difficult to catch fire, on the other hand, partial condensed water can enter an oil pan along the inner wall of the cylinder sleeve, thereby the lubrication of the cylinder sleeve is influenced, the engine oil dilution is caused, the use cost is improved, the engine can be damaged seriously, because certain moisture is contained in the air, the condensed water flows down on the inner wall of the intercooler during temperature reduction, in order to prevent the water from flowing into the combustion chamber after accumulation, a water drain valve needs to be designed, namely, an air inlet system can be sealed when the working state of the engine has air pressure, and the accumulated water flows out under the condition that the air pressure does not exist in the shut down state. In the prior art, most condensed water of an intercooler of a supercharged diesel engine is discharged by a water drain valve arranged at the bottom. When the diesel engine is stopped, the drain valve is unscrewed to drain the condensed water, and when the diesel engine works, the drain valve is screwed down. When a small amount of condensed water is accumulated in the intercooler, the condensed water has little influence on the engine and a cylinder sleeve, but the drain valve needs to be screwed off to drain the condensed water after the condensed water reaches a certain water level.

Thereby the operation of draining needs artifical the unscrewing among the prior art, if personnel forget to drain, can lead to the comdenstion water to get into the engine combustion chamber to the in-process of unscrewing the waterproof valve causes the valve that drains easily and loses the phenomenon.
