Abstract
The utility model discloses a cylinder head of a diesel engine, which comprises a gas inlet pipe, a gas inlet duct and a cylinder head body mounted on the upper surface of a cylinder body, wherein the gas inlet duct is connected and communicated with the interior of the gas inlet pipe, the gas inlet duct and the cylinder head body are integrally formed, and the gas inlet pipe and the gas inlet duct are connected by adopting the flange linkage way. An upper flange is arranged at the lower end of the gas inlet pipe, a lower flange is arranged at the upper end of the gas inlet duct, the upper flange is connected with the lower flange through a fixing bolt, a rubber flat washer is further arranged between the upper flange and the lower flange, the upper flange and the gas inlet pipe are integrally formed, and the lower flange and the gas inlet duct are integrally formed as well. The utility model has the advantages of simple structure and convenient use, and can decompose the structures of the gas inlet pipe and the gas inlet duct on the cylinder head, lead the gas inlet pipe and the cylinder head body after decomposition to exist independently, carry out casting and processing of all parts respectively, reduce the casting difficulty and the scrap rate, and improve the processing precision.
Description
Technical field
The utility model relates to a kind of seal arrangement of combustion engine, relates in particular to a kind of cylinder head, belongs to Diesel Engine Technique Field.
Background technique
At present, cylinder head be installed in cylinder block above, from the top seal cylinder and constitute the firing chamber.It often contacts with high-temperature high-pressure fuel gas, therefore bears very big heat load and mechanical load.The cylinder head inside of water cooled engine is shaped on cooling jacket, and the cooling water hole of cylinder cap lower end surface communicates with the cooling water hole of cylinder body.Utilize circulating water to come high-temperature part such as cooling combustion chamber.Suction tude and intake duct are monolithic construction on the at present domestic and international cylinder cover of diesel, by whole behind the spheroidal graphite cast iron casting suction tude and intake duct are carried out machining, and there is following drawback in this mode: the casting difficulty is big, the reject rate height; Mechanical processing technique is poor, and required precision is difficult to realize that the intake duct inner surface quality is difficult to guarantee; Processing cost is relatively also higher.
The model utility content
At above-mentioned the deficiencies in the prior art part, the utility model provides a kind of Location accuracy height, and processing and fabricating is easy, and the cylinder cover of diesel structure that cost is lower can effectively solve the problem that above-mentioned prior art exists.
To achieve these goals, the technical solution adopted in the utility model is: disclose a kind of cylinder cover of diesel, it comprises suction tude, intake duct and is installed on cylinder head body above the cylinder block, intake duct communicated with inner connection of suction tude, adopt the flange connecting mode to link to each other between described intake duct and this body by integral forming of cylinder head, suction tude and intake duct.
As preferably, the lower end of described suction tude is provided with upper flange, and the upper end of intake duct is provided with lower flange, links to each other by fixing bolt between upper flange and the lower flange, also is provided with the glue plain cushion that seals between upper flange and lower flange.
Further, upper flange and suction tude are one-body molded, and lower flange and intake duct are one-body molded.
Compared with prior art, the beneficial effect that this model utility is brought is: this model utility is simple in structure, the convenient manufacturing processed, the structure of suction tude on the cylinder cap and intake duct is decomposed, cylinder head body after making suction tude and decomposing independently exists, carry out the casting and the processing of each parts respectively, reduced the whole casting difficulty that adds man-hour, reduced reject rate, improved process industrial art performance, realized the anticipate accuracy requirement, the glue plain cushion plays seal action, guarantee the quality of intake duct internal surface, made processing cost guarantee the quality of product when reducing.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, as a kind of embodiment of the present utility model, this cylinder cover of diesel comprises suction tude 1, intake duct 2 and is installed on cylinder head body 3 above the cylinder block, described intake duct 2 and cylinder head body 3 are one-body molded, suction tude 1 is connected with the inside of intake duct 2 and communicates, and adopts the flange connecting mode to link to each other between the housing of suction tude 1 and intake duct 2.Specifically, the lower end of described suction tude 1 is provided with upper flange 6, the upper end of intake duct 2 is provided with lower flange 7, link to each other by fixing bolt 5 between upper flange 6 and the lower flange 7, also be provided with glue plain cushion 4 between upper flange 6 and lower flange 7, upper flange 6 is one-body molded with suction tude 1, and lower flange 7 is one-body molded with intake duct 2, suction tude 1 forms through thick, fine finishing separately by the spheroidal graphite cast iron casting.
More than cylinder cover of diesel structure provided by the utility model has been carried out detailed introduction, used specific case herein principle of the present utility model and mode of execution are set forth, above embodiment's explanation just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
