Abstract
The utility model discloses a retrofitted cylinder cover with improved starting valve holes. The retrofitted cylinder cover comprises a cylinder cover body. The starting valve holes are arranged in the cylinder cover body. Cooling water holes are arranged on near sides of each starting valve hole. The cross section of each starting valve hole is in an oval shape. The cooling water holes are arranged on two sides of short shafts of the oval-shaped starting valve holes. The retrofitted cylinder cover with the improved starting valve holes is reasonable in structure, effectively increases the thickness between the hole wall of each starting valve hole and the hole wall of each cooling water hole on the premise of ensuring compressed air flow in the starting valve holes can not be affected, and achieves the purpose of prolonging the service life of the cylinder cover.
Description
Technical field
The utility model relates to a kind of diesel engine cylinder cover.
Background technique
Cylinder cap is one of easily damaged parts of the diesel engines such as SULZER RND-M, RL, do not take into full account the thickness problem that starts between valve opening hole wall and the Cooling Holes hole wall because starting when valve opening designs, thickness deficiency and cooling water corrosion produce hole wall and tear water leakage phenomenon between very easily occurring because of hole wall after the use.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and the renovation cylinder cap of the startup valve opening remodeling of long service life starts the renovation cylinder cap of valve opening remodeling.
Technical solution of the present utility model is:
A kind of renovation cylinder cap that starts valve opening remodeling, comprise the cylinder cap body, the startup valve opening is set on the cylinder cap body, start the valve opening nearside cooling water hole is set, it is characterized in that: start the cross section ovalize of valve opening, cooling water hole is positioned at the oval minor axis both sides that start valve opening.
The utility model is rational in infrastructure, guaranteeing not affect under the prerequisite that starts valve opening compressed air flow, effectively increases the thickness that starts between valve opening hole wall and the Cooling Holes hole wall, reaches to prolong the cylinder cap purpose in working life.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an embodiment's of the utility model structural representation.
Fig. 2 is the cross-sectional view that starts the valve opening position.
Embodiment
A kind of renovation cylinder cap that starts valve opening remodeling, comprise cylinder cap body 1, startup valve opening 2 is set on the cylinder cap body, start the valve opening nearside cooling water hole 3,4 is set, start the cross section ovalize of valve opening, cooling water hole 3,4 lays respectively at the oval minor axis both sides that start valve opening.
During manufacturing: adopt the overlaying method weldering full original startup valve opening.Verification starts the valve opening central datum line, marks to change the shape zone, adopts machine-tooled method to change former orifice shapes into kidney-shaped (namely oval) by circle hole shape.Remove hole inner burr, wedge angle after the machining processing, hand grinding makes in the hole level and smooth.
Claims (1)
1. one kind starts the renovation cylinder cap that valve opening is retrofited, comprise the cylinder cap body, the startup valve opening is set on the cylinder cap body, start the valve opening nearside cooling water hole is set, it is characterized in that: start the cross section ovalize of valve opening, cooling water hole is positioned at the oval minor axis both sides that start valve opening.
