Abstract

The utility model relates to a cylinder gland bush, in particular to an all-metal gland bush used in a diesel engine. The cylinder gland bush is characterized in that the bush body is made of an upper, a middle, and a lower meal plates, and the three layers are joined together to one part by bolt holes in the bush body, tappet hole tipping and cylinder hole flanging. The cylinder hole, water pore and oil hole are all used the unique way of airproof. The bush can not only improve the reliability and durability of the engine, reduce the number of charging the cylinder bush, and improve work efficiency, but also is good to environmental protection both in material using and engine exhaust.

Description

Diesel engine full-metallic head gasket

The utility model relates to a kind of cylinder packing, the full-metallic head gasket of using on especially a kind of diesel engine.

Mainly seal between engine body and the cylinder cap by head gasket, what present domestic 90% head gasket was still Ashestos plate and the iron plate of making a spurt is composited, wherein main sheet material is Ashestos plate, poor because of its environmental-protecting performance, now abroad some developed countries have forbidden production; The cylinder mouth of asbestos slate composite pad, water hole guard ring adopt the metal bound edge to make more, and its withstand voltage properties is poor, motor easily towards cylinder, leak.

The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, and a kind of reliable performance, stay-in-grade environment protection type diesel engine full-metallic head gasket are provided.

For achieving the above object, the technical solution adopted in the utility model is: a kind of diesel engine full-metallic head gasket, pad is provided with cylinder-bore, water hole, tappet bore and bolt hole and oilhole, its characteristics are, pad is made by upper strata sheet metal, middle level sheet metal, lower metal plate three-ply metal, and three-ply metal is to lean on tappet bore and bolt hole bound edge and cylinder-bore flange to be connected as a single entity; Or lean on cylinder-bore flange and sheet metal peripheral intervals flange to be connected as a single entity.

Above-described cylinder-bore is to seal at the arc ripple that the compacting of place, cylinder hole forms by thicker middle level sheet metal; The water hole is to be sealed by the ripple that upper strata sheet metal and the compacting of lower metal plate form; Oilhole is inner metal inlaying skeleton, casts oil resistant rubber ring sealing outward; All be coated with gasket coating between the upper and lower outer surface of pad and the plate of three-ply metal and the plate.

Compared with the prior art the utility model can not only improve reliability, the durability of motor, reduces the replacing number of times of cylinder pad, increases work efficiency, and aspect the discharging of the use of material and motor, all helps environmental protection.

Below in conjunction with drawings and Examples the utility model is further described.

Referring to Fig. 1-Fig. 9, the pad 1 of full-metallic cylinder of diesel engine pad described in the utility model is made by upper strata sheet metal 7, middle level sheet metal 8, lower metal plate 9 three-ply metals, pad 1 is provided with cylinder-bore 2, water hole 3, tappet bore 4 and bolt hole 5 and oilhole 6, and the upper, middle and lower-ranking sheet metal is to lean on bolt hole 5 and tappet bore 4 bound edges and cylinder-bore 2 flange to be connected as a single entity; For the sealability and the working life of improving head gasket, adopted unique sealing means, cylinder-bore 2 is to seal at the arc ripple that the compacting of place, cylinder hole forms by thicker middle level sheet metal 8; Water hole 3 is to be sealed by the ripple that upper strata sheet metal 7 and 9 compactings of lower metal plate form; Oilhole 6 is inner metal inlaying skeletons 10, casts oil resistant rubber ring 11 sealing outward; All be coated with gasket coating between the upper and lower outer surface of pad 1 and the plate of three-ply metal and the plate and reach sealing effect.

Above-mentioned full-metallic cylinder of diesel engine pad; withstand voltage, resistance to high temperature good; good sealing effect; long service life; and it is pollution-free; be beneficial to environmental protection, be mainly used in 6110, the 6106 diesel engine head gaskets etc. of 6CK, 6DF1,6DE2 type and Dalian Diesel Engine Plant of 6114 types, the Wuxi Diesel Engine Plant of Shanghai Diesel Engine Plant.
