Abstract
A cylinder cover provided by the utility model comprises a turbination sidewall (1) closed with a top plate (2) and a base plate (3). A central diaphragm (4) divides a chamber of the cylinder cover into an upper cooling water chamber and a lower cooling water chamber (5, 6). 12 lug bosses (12) are uniformly distributed on the sidewall (1) of the lower water chamber, each of the lug bosses (12) is provided with a T-shaped X-type water pore (13). Cooling water from a cylinder liner passes through the T-shaped X-type water pores (13) and enters the lower cooling water chamber (6) of the cylinder cover. Prior water jacket and O-ring seal are cancelled, performance of a diesel engine is improved and maintenance expense is reduced.
Description
Technical field
The utility model belongs to Diesel Engine Technique Field, relates in particular to a kind of novel cylinder cover for diesel engine.
Background technique
The cylinder head of high-power diesel engine adopted the vertical sidewall structure originally, and base plate directly is sitting on the cylinder seal pad stressed, was very easy to produce fatigue crack.Changed up big and down small turbination sidewall structure afterwards into, it is stressed that water cavity side wall lower ends rather than base plate are sitting on the cylinder seal pad, thereby improved the stressing conditions of cylinder head.But this need adopt the water inlet pattern that water jacket was set outside sidewall, promptly has radially water inlet on the lower cooling water cavity corresponding side walls, and crossing between water jacket and the cylinder head that this sidewall is outer realizes sealing by O-ring seals.This not only makes structure become comparatively complicated, and in installation process, chew O-ring seals easily, in the running of diesel engine, distortion causes leaking thereby O-ring seals also is subjected to heat ageing easily in addition, and the performance of diesel engine and the expense of maintenance are all seriously influenced.
Summary of the invention
The purpose of this utility model overcomes the deficiency of above-mentioned prior art exactly, the novel diesel machine cylinder head that provides a kind of designs simplification, performance to improve.
The purpose of this utility model is existing like this: a kind of cylinder cover for diesel engine, the box-shaped cylinder body of forming by the turbination sidewall of top board and base plate sealing, be provided with in the cylinder body its cavity is separated into, the central diaphragm of following two cooling water chambeies, have the central through bore that the oil nozzle sheath is installed in the cylinder body central vertical in top board and base plate, around this central through bore, be furnished with two intake valve mounting hole and two exhaust valve mounting holes that run through top board and base plate, be positioned at the same level height in sidewall middle part of cooling water chamber, vertical center line along the cylinder body horizontal projection, the oriented central through bore of cloth both sides are bent downwardly 90 degree symmetrically, and polyphone is communicated with the admission line of two intake valve mounting holes on the base plate and the exhaust duct of two exhaust valve mounting holes respectively, the T-shaped cross type water passage hole that evenly distributes and communicate with cooling water chamber on the water cavity sidewall under it is characterized in that, the outside of water passage hole seals with cone blocking.
In order to realize the purpose of this utility model better, be evenly distributed with boss on the water cavity sidewall down described, described T-shaped cross type water passage hole is positioned on this boss.
The technical solution of the utility model owing to cancelled cylinder head and cross water jacket and O-ring seal, causes the problem of leaking, thereby has improved the performance of diesel engine with regard to not existing O-ring seal to be chewed or be subjected to the heat ageing distortion, reduced the expense of maintenance.
Description of drawings
Accompanying drawing 1 is the utility model embodiment's the principle schematic of facing.
Accompanying drawing 2 is that the A-A of accompanying drawing 1 is to generalized section.
Embodiment
Referring to Fig. 1, cylinder cover for diesel engine of the present utility model is a box-shaped cylinder body, is formed through top board (2) and base plate (3) sealing by turbination sidewall (1).Be provided with spherical central diaphragm (4) in the cylinder body, its cavity is separated into upper and lower two cooling water chambeies (5,6).Have central through bore (7) in the cylinder body central vertical in top board (2) and base plate (3), be used to install the oil nozzle sheath.Be furnished with two intake valve mounting hole (8) and two exhaust valve mounting holes (9) that run through top board (2) and base plate (3) on every side at this central through bore (7), be positioned at the same level height in sidewall (1) middle part of cooling water chamber (5), vertical center line along the cylinder body horizontal projection, be furnished with symmetrically and be bent downwardly 90 degree in central through bore (7) both sides, and polyphone is communicated with the admission line (10) of two the intake valve mounting holes (8) on the base plate (3) and the exhaust duct (11) of two exhaust valve mounting holes (9) respectively, be evenly distributed with 12 boss (12) on the following water cavity sidewall (1), each boss (12) is provided with T-shaped cross type water passage hole (13), the inner of water passage hole (13) horizontal component is communicated with lower cooling water cavity (6), and the outer end seals with cone blocking (14).The lower end of water passage hole (13) vertical component is communicated with water jacket.
Diesel engine when work, through T-shaped cross type water passage hole (13), enter the lower cooling water cavity (6) of cylinder head from the cooling water of cylinder liner.
Claims (2)
1, a kind of cylinder cover for diesel engine, the box-shaped cylinder body of forming by the turbination sidewall (1) of top board (2) and base plate (3) sealing, be provided with in the cylinder body its cavity is separated into, the central diaphragm of following two cooling water chambeies (4), have the central through bore (7) that the oil nozzle sheath is installed in the cylinder body central vertical in top board (2) and base plate (3), be furnished with two intake valve mounting holes (8) and two the exhaust valve mounting holes (9) that run through top board (2) and base plate (3) on every side at this central through bore (7), be positioned at the same level height in sidewall (1) middle part of cooling water chamber (5), vertical center line along the cylinder body horizontal projection, be furnished with symmetrically and be bent downwardly 90 degree in central through bore (7) both sides, and polyphone is communicated with the admission line (10) of two the intake valve mounting holes (8) on the base plate (3) and the exhaust duct (11) of two exhaust valve mounting holes (9) respectively, it is characterized in that water cavity sidewall (1) is gone up the T-shaped cross type water passage hole (13) that evenly distributes and communicate with cooling water chamber down, cone blocking (14) sealing of the outside of water passage hole (13).
2, cylinder cover for diesel engine according to claim 1 is characterized in that being evenly distributed with boss (12) on described lower cooling water cavity (6) sidewall (1), and described T-shaped cross type water passage hole (13) is positioned on this boss (12).
