Description
Technical field
The utility model relates to outlet valve field, specifically a kind of outlet valve of cooling water of internal combustion engine pipe.
Background technique
Water-cooling tube is one of indispensable component in internal-combustion engine cooling system circulation, play the effect connecting internal combustion engine main body cooling system and car load radiator, warm braw, expansion tank, set up whole cooling system circulating cooling liquid circulation passage, get rid of excessive gas in cooling system.
At present, because design of Cooling System trends towards simplifying, reduce amount of parts in pipeline as far as possible, ensure system layout at utmost generalization.And some pipeline is because arranging reason, position is higher, when static state is annotated, because cooling liquid is overflow up from system bottom, and cause partial air to be stacked in the higher pipeline of layout going, cannot effectively discharge, cooling system can be caused to annotate discontented and in systemic circulation, form vapour lock, thus the stability of influential system, even cause the inefficacy of system and the damage of some component.
Model utility content
The purpose of this utility model is the outlet valve of the cooling water of internal combustion engine pipe providing a kind of structure simple, easy to use, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
A kind of outlet valve of cooling water of internal combustion engine pipe, comprise valve seat and valve gap, described valve seat is threaded with valve gap, the lower end of described valve seat is connected with extraneous water-cooling tube, the bottom of valve seat offers vent, through hole is provided with in the middle of the upper end of described valve gap, the top of described through hole is provided with exhaust port, the upper-end surface of valve gap is provided with dust cover, hollow cavity is formed between valve gap and valve seat, the lower slide of described hollow cavity is connected with kickboard, the post that blocks water is provided with in the middle of the upside of described kickboard, left and right two-part of the described post that blocks water all offer breather line, the outer cover of post of blocking water has spring, described spring upper end is connected with hollow cavity upper end, lower spring end is connected with hollow cavity lower end.
As further program of the utility model: described in the post upper end that blocks water be set to taper shape.
As further program of the utility model: described exhaust port lower end is set as the shape matched with the post upper end that blocks water.
As the utility model further scheme: described in the post upper end that blocks water put in through hole.
Compared with prior art, the beneficial effects of the utility model are: this device is the principle according to hydromechanical negative-pressure ward, utilize the physical property of gas and fluid density difference, a kind of pressure drive mechanism of design.It relies on the density difference of air and water liquid, and produce varying in size of suction force during flowing, valve port can only make gas pass through, and closes liquid.General under identical gap, gas by the suction force that produces far below liquid by time the suction force that produces, its difference generally can reach more than 3 times, when such as, pressure in water channel reaches 4 barometric pressure, valve air relief gas by time can not be obstructed, can also exit rapidly, and when running into 1.5 atmospheric water liquid, valve is just closed automatically.The feature of this bleed valve is that venting is fast, blocking solution is sensitive, also the spring selected by can adjusting according to real needs, set the pressure range that it adapts to, outlet valve top is provided with dust cover, open dust cover during use can be vented, cover dust cover can prevent dust or other objects from falling into outlet valve what be not vented, outlet valve is blocked, increase the working life of outlet valve, valve seat and valve gap are threaded, convenient disassembly, when outlet valve breaks down, facilitates maintenance and inspection.
