Problems solved by technology

On the one hand, the reduction of coolant makes the cooling system unable to meet the required cooling effect; on the other hand, the exhaustion of air and coolant at the same time causes the engine to warm up for a long time, and the heating effect is not good under low temperature conditions

Embodiment Construction

[0009] Such as figure 1 , 2 As shown, the present invention provides a venting and liquid blocking stop valve, which can be used on the engine outlet pipe to realize the functions of venting and liquid blocking. Specifically, it can ensure the removal of gas and prevent the discharge of coolant at the same time. The technical solution includes a cavity 21 for accommodating the piston 10, the cavity 21 is located in the valve body 20, the valve body 20 is provided with input and output pipelines 22, 23, and the junction of the input and output pipelines 22, 23 and the cavity 21 The diameter of the hole is smaller than the cross section of the piston 10. The piston 10 can move or float or swim in the cavity 21, and the gas discharged through the engine outlet pipe enters the ventilation and liquid resistance stop valve and is discharged smoothly, and when there is liquid discharged, the force of the liquid is relatively large, which will push the piston 10 Move and block the i...

Abstract

The invention relates to a stop valve capable of ventilation and preventing liquid from passing, which comprises a hollow cavity accommodating a piston, wherein the hollow cavity is positioned inside a valve body which is provided with an input/output pipeline and the aperture of the junction between the input/output pipeline, and the hollow cavity is smaller than the section of the piston. Such a ventilation liquid-preventing stop valve is mounted in an exhaust pipe of an engine in order to realize the smooth exhaustion of gas inside the engine, thereby guaranteeing the successful filling of anti-freeze fluid and preventing the anti-freeze fluid from flowing to an expansive kettle from the exhaust pipe of an engine, avoiding the reduction of circulating cooling fluid, shortening the time of low temperature machine, and ensuring favorable heating effect of the engine.

Description

technical field [0001] The invention relates to a cut-off valve capable of ventilating and preventing liquid from passing through. Background technique [0002] When the engine is working, the coolant needs to be cooled. During the process of heat exchange between the coolant and the cylinder block, the temperature of the coolant will rise, so there is a high-temperature gas that needs to be discharged. Some engines have an air outlet that is directly the same as the atmosphere, and some are connected to the expansion kettle, [0003] In this way, when the temperature of the cooling liquid rises, its volume increases accordingly, and along with the discharge of high-temperature gas, some cooling liquid is discharged to the atmosphere, and some is discharged to the expansion kettle. On the one hand, the reduction of coolant makes the cooling system unable to meet the required cooling effect; on the other hand, the simultaneous removal of air and coolant leads to long engine ...
