Abstract
The utility model discloses a piston cylinder sleeve, which is provided with a valve-avoiding hole and a sealing groove. At present, high strength and low temperature expansion materials are used on a piston with the structural type, thereby enabling cost to be lower and being capable of keeping working under severe working conditions of heavy oil burning, high explosive pressure and the like.
Description
Technical field
The utility model relates to a kind of piston cylinder liner.
Background technique
In the existing technology, the seal groove excesssive gap that piston-cylinder puts, cause piston cylinder liner precision is not enough.
Summary of the invention
The purpose of the utility model provides a kind of piston cylinder liner.
The utility model for realizing the technological scheme that above-mentioned purpose adopted is: a kind of piston cylinder liner, said cylinder liner are provided with keeps away valve cave and seal groove.
Said seal groove is five.
It is that Φ is 346mm that said cylinder liner is installed internal diameter.
It is that Φ is 386mm that said cylinder liner is installed external diameter.
A kind of piston cylinder liner of the utility model, the material that present high tenacity, low temperature expand has been used for this structural type piston, makes cost more cheap, and can be under abominable operating mode such as burning heavy oil, high detonation pressure, continual work.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation of a kind of piston cylinder liner of the utility model.
Fig. 2 is the sectional view of a kind of piston cylinder liner of the utility model.
