Abstract
The utility model discloses a sealed isolation structure for an ignition system and a cylinder cover of an automotive engine. The sealed isolation structure comprises an ignition plug locating sleeve and the cylinder cover, wherein the ignition plug locating sleeve is sealed at two ends, the upper end of the ignition plug locating sleeve is sealed by an O ring, and the lower end of the ignition plug locating sleeve is sealed by processing threads on a sleeve body and the inner wall of a hole of a cylinder cover locating sleeve and arranging a gasket. The sealed isolation structure can effectively prevent shake and looseness in the process of replacing an ignition plug, ensures that vibration looseness is not generated during work of the engine and looseness is not generated in the process of replacing the ignition plug, and ensures that cooling water cannot be leaked and oil in a valve chamber cover cannot be leaked outside or leaked to the ignition plug.
Description
Technical field
The utility model relates to a kind of parts of motor car engine, specifically the seal isolation structure of a kind of natural gas vehicle engine ignition system and cylinder cap.
Technical background
The cylinder cap of existing Natural Gas motor comprises the spark plug setting sleeve and the cylinder body that are separated from each other, after cylinder body and spark plug setting sleeve coordinate, intermediate portion forms cylinder body water route, spark plug setting sleeve upper end is sealed by O type circle, and lower end relies on interference fit seal.Due to two kinds of part material differences, after expanding with heat and contract with cold, interference fit easily lost efficacy, and therefore in replacing spark plug process, spark plug setting sleeve and cylinder body are easily loosening, cause cooling water leakage, and safety in utilization reduces greatly.
Summary of the invention
Technical problem to be solved in the utility model is to propose spark plug setting sleeve and cylinder body in a kind of spark plug Renewal process and can not becomes flexible, and can not cause the seal isolation structure of automotive engine ignition system and the cylinder cap of cooling water leakage danger.
For solving the problems of the technologies described above, the seal isolation structure of a kind of automotive engine ignition system of the utility model and cylinder cap comprises spark plug setting sleeve and cylinder cap, described spark plug setting sleeve adopts sealed at both ends, O type circle sealing for its upper end, its lower end adopts on described body and cylinder cap setting sleeve perforate inwall machining screw and adds pad and seals.
The seal isolation structure of above-mentioned a kind of automotive engine ignition system and cylinder cap, lock with locking nut on the top of described spark plug setting sleeve.
The seal isolation structure of above-mentioned a kind of automotive engine ignition system and cylinder cap, it also includes valve-chamber cover, the outer cover of described valve-chamber cover is provided with high voltage wire sleeve pipe, the lower end of described valve-chamber cover adopts on described high voltage wire sleeve pipe and cylinder cap trepanning inwall, to process locking screw and add O type circle and seals, and the upper end of described valve-chamber cover adopts O type circle and locking nut to seal.
The utility model is owing to having adopted above-mentioned technical pattern, can effectively prevent vibrations and becoming flexible in replacing spark plug process, while guaranteeing engine operation, can there are not vibrations and get loose and change loosening in spark plug process, guarantee that cooling water can not leak and valve-chamber cover in machine oil can not leak or leak into spark plug.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model seal isolation structure.
Embodiment
As shown in Figure 1, the seal isolation structure of the utility model automotive engine ignition system and cylinder cap comprises spark plug setting sleeve 1, cylinder cap 2 and valve-chamber cover 4, spark plug setting sleeve 1 adopts high-quality stainless steel make and adopt sealed at both ends, its upper end seals with O type circle 11, and its lower end adopts on body and cylinder cap setting sleeve perforate inwall machining screw 12 and adds red copper pad 13 and seals.Lock with locking nut 5 on the top of spark plug setting sleeve 1, prevents vibrations and becoming flexible in replacing spark plug process, and the vibrations that produce while guaranteeing engine operation get loose and change not becoming flexible in spark plug process, guarantee that cooling water can not leak.For preventing that valve-chamber cover machine oil from sealing in ignition system or to escaping, the outer cover of valve-chamber cover 4 is provided with high voltage wire sleeve pipe 6 and is isolated, the lower end of valve-chamber cover 4 adopts to process locking screw 61 and add O type circle 41 on high voltage wire sleeve pipe 6 and cylinder cap trepanning inwall and seals, and guarantees the sealing between ignition system and valve cage; The upper end of valve-chamber cover 4 adopts O type circle 42 and locking nut 43 to seal, and guarantees that valve-chamber cover machine oil is not to external leakage.
