Abstract

The invention discloses a loader cylinder cover structure installed on the upper portion of a cylinder body. The structure comprises a cylinder cover, an oil injection hole is formed in the center of the cylinder cover, a valve seat is arranged on the inner side of the cylinder cover, a cooling water cavity is arranged between the valve seat and the cylinder cover, a sealing ring is arranged on one side of the cooling cavity located on the valve seat, and a valve is arranged in the valve seat. The cylinder cover is made of QT70-3 nodular cast iron. The cylinder cover structure has the advantages of being simple in structure and good in sealing performance.

Description

A kind of loader cylinder head arrangement
Technical field
The invention belongs to loader accessory technical field, relate to loader cylinder head arrangement.
Background technique
Loader cylinder ubiquity cylinder head valve-seat bore water cavity sealing position etching problem, even because cylinder head valve-seat bore inwall forms etch pit, occurs that seal failure causes the phenomenon of leaking.Cold water leaks and causes combustor inner cylinder abnormal, and cooling water chamber can be caused time serious to penetrate, and cooling water enters in cylinder, causes cylinder head, piston rod or bent axle to be scrapped, has harm to motor.
Summary of the invention
The present invention is intended to the defect overcoming prior art, provides a kind of loader cylinder head arrangement, has structure simple, the feature that sealed type is good.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of loader cylinder head arrangement, be contained in cylinder deck, comprise cylinder head 1, cylinder head 1 central authorities are nozzle opening, valve seat insert 4 is had inside cylinder head 1, be provided with cooling water chamber 5 between valve seat insert 4 and cylinder head 1, the side that cooling cavity 5 is positioned at valve seat insert is provided with seal ring 3, is provided with air valve 2 in valve seat insert 4.
Further, cylinder head material is the spheroidal graphite cast iron of QT70-3.
Compared with prior art, the present invention has following beneficial effect:
Plastic piece structure of the present invention is simple, and sealed type is good.And have good tensile strength, corrosion resistance, can the corrosion test in high flow rate current use.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of loader cylinder head arrangement of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of loader cylinder head arrangement, is contained in cylinder deck to embodiment, comprises cylinder head 1, and cylinder head material is the spheroidal graphite cast iron of QT70-3.Cylinder head 1 central authorities are nozzle opening, have valve seat insert 4, be provided with cooling water chamber 5 between valve seat insert 4 and cylinder head 1 inside cylinder head 1, and the side that cooling cavity 5 is positioned at valve seat insert is provided with seal ring 3, is provided with air valve 2 in valve seat insert 4.
Last it is noted that the foregoing is only explanation embodiments of the present invention; be not limited to the present invention; for a person skilled in the art; within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.

Claims (2)
