Abstract
The utility model discloses an air bleeder for cylinder head water tube, relating to the cylinder head body of the motor on which a head water tube is arranged. On every head body a relief port over the head water tube is provided, on which a relief pipe is arranged to conduct the air in the head water tube out. The utility model reduces the height of the whole construction, simplifies the design of the let-off pipe, ensuring that the air exhaust of water tube on every cylinder head body can be carried out respectively and on time, improving the air exhaust results.
Description
Technical field
The utility model relates to the technical field on a kind of motor, especially relates to the cylinder head water cavity means of deflation on a kind of cylinder
Background technique
Because the work characteristics of motor, need cool off the motor of proper functioning to guarantee the proper functioning of motor, current, the type of cooling to motor mainly contains water-cooled and air-cooled dual mode, wherein, main application is the water-cooled cooling on big-block engine, promptly adopts to be provided with cooling water circulating device to realize the cooling to cylinder on the cylinder cap of cylinder.But, because cooling water has gas to exist in carrying out cool cycles often, this influence to the cooling effect of motor is very big, venting mode commonly used is at present established an air vent to realize the gas purging in the cooling water above the cylinder cap outlet pipe, but there is certain shortcoming in venting in this way: at first, this mode of giving vent to anger requires the height of outlet pipe water cavity must be higher than the height of cylinder head water cavity, has so just increased the height of complete machine, also increases the unnecessary quality of outlet pipe; Secondly, no matter the air outlet is arranged in which position of outlet pipe, when garage is walked, or is going up a slope, or may have sometime at descending that section can not well be got rid of gas.If water temperature is too high, can cause piston scraping, cylinder cap to produce a series of problems relevant such as thermal stress with water cycle.
Summary of the invention
The technical problems to be solved in the utility model has provided a kind of cylinder head water cavity means of deflation, it realizes the gas in the cooling circulating water in the cylinder cap lid is bled off under the situation that does not increase motor complete machine height, and guaranteed the exhaust in time separately of each cylinder cap water cavity, made exhaust effect better.
For solving the problems of the technologies described above, the technical solution of the utility model is: cylinder head water cavity means of deflation, relate to the cylinder cap lid on the motor, be provided with the cylinder cap water cavity in the cylinder cap lid, all be provided with the air vent that is positioned at cylinder cap water cavity top on described each cylinder cap lid, air vent is provided with the exhaust tube that the gas in the cylinder cap water cavity can be led away.
As a kind of optimal way, described exhaust tube connects all air vent serial connections.
Optimize mode as another kind, described air vent and exhaust tube wire connection are fixed.
Optimize mode as another kind, described air vent is positioned at the topmost part of cylinder cap lid upper cylinder cover water cavity.
Adopt the cylinder head water cavity means of deflation of said structure, owing to be on each cylinder cap lid, to be equipped with the air vent that is communicated with water cavity top, by the exhaust tube that is communicated with air vent the gas in the cooling water in the water cavity is discharged, the height of this venting mode outlet pipe water cavity needn't be higher than the height of cylinder head water cavity, so just reduced the height of complete machine, simplify the outlet pipe design, and this kind structure is when vehicle to run, because each cylinder can exhaust, therefore water cavity can not occur deposits the gas phenomenon, guaranteed the water cavity exhaust in time separately in each cylinder head cylinder cap lid, made exhaust effect better.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Fig. 1 is the side view of a cylinder head of cylinder head water cavity means of deflation of the present utility model;
Fig. 2 is the sectional view among the A---A among Fig. 1;
Fig. 3 is a cylinder head water cavity means of deflation structural representation of the present utility model.
Embodiment
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of cylinder head water cavity means of deflation of the present utility model is: relate to the cylinder cap lid 1 on the motor, but in cylinder cap lid 1, be provided with the but cylinder cap water cavity 11 of water cycle of cooling, on each cylinder cap lid 1, all be provided with the air vent 12 that is positioned at cylinder cap water cavity 11 tops, on air vent 12, be provided with the exhaust tube 2 that the gas in the cylinder cap water cavity 11 can be led away.For the convenience of installing and using, air vent 12 can adopt wire connection to fix with exhaust tube 2, and air vent 12 can be located at the topmost part of cylinder cap lid 1 upper cylinder cover water cavity 11,2 serial connections of exhaust tube between each cylinder cap are connected, because cylinder head water cavity 11 is engine cooling water circuit highest points, air vent 12 is opened at cylinder cap water cavity 11 highest points, and each cylinder separately after the exhaust like this, gas compile through steel pipe and enter swelling water tank.
