Abstract
The invention relates to a sealing structure of a sparking plug steel bushing. The sealing structure of the sparking plug steel bushing comprises a sparkling plug, a cylinder head, the sparking plug steel bushing, an O-shaped rubber ring, a gland and a copper washer. The sparking plug is placed on the top of the cylinder head, and the bottom of the sparking plug is screwed into the cylinder head. The sparking plug steel bushing is arranged on the sparking plug in a sleeved mode, and the cylinder head is connected with the sparking plug steel bushing through the O-shaped rubber ring. The bottom of the sparking plug steel bushing is connected with the cylinder head through the copper washer, and the gland is screwed into the sparking plug steel bushing. The upper portion of the sealing structure is sealed by the O-shaped rubber ring, the lower portion of the sealing structure applies pressure to the gland, then the pressure is transmitted o the copper washer through the sparking plug steel bushing to enable the copper washer to be stressed and deformed, the copper washer is in surface contact with the cylinder head to seal cooling water, the cooling water is prevented from entering a combustion chamber, and the sparking plug is directly screwed on the cylinder head. The structural arrangement of the sealing structure enables the sealing performance to be more enduring and effective, and regular replacing and maintaining of the sparking plug are facilitated.
Description
Technical field
The present invention relates to a kind of spark plug steel bushing hermetically-sealed construction.
Background technology
Spark plug (spark plugs), is commonly called as nozzles, and its effect is the high voltage pulse discharge of electricity that high-voltage conducting wires is sent here, and air between disruptive spark plug two electrodes produces electric spark with the mist in this cylinder that ignites.Main Types has: pseudotype spark plug, edge body projected nose type spark plug, electrode type spark plug, seat type spark plug, polar form spark plug, face arcing type spark plug etc.The function of spark plug is that the high-tension electricity of volts up to ten thousand is introduced to combustion chamber, and produces electric spark and light gaseous mixture, coordinates and makes engine work done with ignition system and oil supply system, is jointly determining to a great extent the performance of engine.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of spark plug steel bushing hermetically-sealed construction that meets the requirement of spark plug exclusion of water oil.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of spark plug steel bushing hermetically-sealed construction, comprise spark plug, cylinder cap, spark plug steel bushing, O type rubber ring, gland and copper washer, described spark plug is positioned at described cylinder cap top, and its bottom is screwed in described cylinder cap, described spark plug steel bushing is sleeved on described spark plug, described cylinder cap is connected with described spark plug steel bushing by described O type rubber ring, the bottom of described spark plug steel bushing is connected with described cylinder cap by described copper washer, and described gland is screwed in described spark plug steel bushing.
The invention has the beneficial effects as follows:
In the present invention, part adopts the seal with elastometic washer of O type, bottom makes its stressed modification by spark plug steel bushing transmission of pressure to copper washer again by gland is exerted pressure, copper washer contacts to seal cooling water with cylinder cap face, prevent that cooling water from entering combustion chamber, and spark plug has directly been screwed on cylinder cap, it is more effectively lasting that this novel structural configuration makes it sealing property, and be convenient to the periodic replacement maintenance of spark plug.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described spark plug comprises metal shell, central electrode and L shaped strip lateral electrode, described central electrode is located in described metal shell, and described L shaped strip lateral electrode is welded on the front port of described metal shell, and the bottom of described metal shell is screwed in described cylinder cap.
Adopt the beneficial effect of above-mentioned further scheme to be; L shaped strip lateral electrode is thickened to broadening and shorten its length and come faster the heat in cylinder to be conducted to the metal shell to spark plug; the insulative body portion of central electrode front end is divided and is designed to not expose; the high temperature being brought to adapt to alcohol fuel burning, effectively protects central electrode.
Further, the bottom of described metal shell adopts and is threaded with described cylinder cap.
Further, described spark plug steel bushing is upper and lower cylinder hollow structure.
Further, the cross section of described copper washer is ellipsoid.
Accompanying drawing explanation
