Abstract
The utility model discloses a magnetic self-sealing piston ring. The magnetic self-sealing piston ring is characterized in that the joint of the piston ring is in an up-down overlap joint structure; each joint side of the joint of the upper overlap joint and the lower overlap joint is provided with a sloped side; the joint forms upper wedged joint space and lower wedged joint space; the direction of the diameter of the upper wedged joint space and lower wedged joint space are opposite; the upper wedged joint space and lower wedged joint space are respectively provided with magnetic blocks; two sides of the magnetic block are connected with the joint sides of the piston ring. When the outer diameter of the piston ring wears away in operation, the two joint sides can split and the joint can become bigger. The magnetic blocks in the upper wedged joint space and lower wedged joint space slide the sealing worn interface under the action of the air pressure and the pressure on the inner diameter of the piston ring, and can prevent the natural gas from leaking. The utility model has the advantages of complete air sealing, simple structure, easy manufacturing, convenient installation, and long service life. Besides, the utility model can overcome the harmful effects caused by gravity and inertance, and can seal air in the whole circulation process.
Description
Technical field
The utility model relates to a kind of magnetic automatic sealing piston ring that is used for field of internal combustion engine.
Background technique
Chinese patent discloses name and has been called: the patent of " sealing type piston ring that a kind of internal-combustion engine is used " (patent No. 01230249), this patent is to utilize to be superimposed with each other to take a mouthful surface of contact one of formation, respectively there is one to take a mouthful slotted eye in the centre of these two table tops, in taking mouthful slotted eye, can inject catch sealing together, the sealing catch is made with steel disc, the also gapped existence in the both sides of taking mouthful surface of contact, and this kind structure difficulty of processing is big, inconvenience is installed, and envelope gas effect is undesirable.
Summary of the invention
The purpose of this utility model just provides and a kind ofly can either overcome the harmful effect that gravity and inertia cause, and envelope gas is thorough, and simple in structure, be easy to processing, easy for installation, and can realize whole circulation process envelope gas, the magnetic automatic sealing piston ring that the life-span prolongs.
Solution of the present utility model is such: at each edge fit of taking mouthful seam crossing up and down is hypotenuse, form two radially opposite splayed joint spaces up and down at seam crossing, be separately installed with magnetic block in seam space up and down, two limits of magnetic block and the edge fit of piston ring join.In use, the external diameter of piston ring back two edge fits that are worn will separate, and it is big that seam becomes, and the magnetic block of installing respectively in seam space up and down is at gas pressure and act on the pressure lower slider sealing wear excuse of piston ring internal diameter, prevents gas leakage.
The utility model has the advantages that: 1, adopt the magnetic positioning sliding block, overcome the harmful effect that gravity and inertia cause, envelope gas is thorough, simple in structure, is easy to processing, and is easy for installation; 2, in two radially opposite splayed joint spaces up and down that seam crossing forms and load onto magnetic block, the two-way envelope gas of last lower interface realizes that the whole circulation process seals gas; 3, adopt slide block under gas pressure, fill in the sealing-in mouth, equilibrium piston ring tension force everywhere, both improved envelope gas effect, prolonged the life-span of piston ring again.
Description of drawings
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is the structural representation of the utility model when free state.
Accompanying drawing 2 is magnetic block of the present utility model structural representations to piston ring radial direction slipper seal wearing and tearing interface.
Accompanying drawing 3 is magnetic block of the present utility model structural representations to piston ring opposite direction slipper seal wearing and tearing interface radially.
Embodiment
The utility model includes piston ring 1, magnetic voussoir 2.
The seam of piston ring 1 is for taking mouth structure up and down, at each edge fit of taking mouthful seam crossing up and down is hypotenuse, form two radially opposite splayed joint spaces up and down at seam crossing, be separately installed with magnetic block 2 in seam space up and down, two limits of magnetic block 2 and the edge fit of piston ring 1 join.
Be hypotenuse at two edge fits taking mouthful seam crossing up and down, two hypotenuses of 2 two hypotenuses of magnetic block and piston ring 1 join.
In the present embodiment, the seam of piston ring 1 is for taking mouth structure up and down, and at seam crossing two pairs of edge fits being arranged is hypotenuse, forms two radially opposite splayed joint spaces up and down at seam crossing, forms fan-shaped chute; Fan-shaped chute towards cylinder is radially radially identical with piston ring, the fan-shaped chute of cylinder is radially opposite with piston ring dorsad, it is the magnetic block 2 of hypotenuse that both sides are installed in the seam space is fan-shaped chute, and both sides have two hypotenuses of magnetic block 2 of hypotenuse and the edge fit of piston ring 1 to join.Both sides have the magnetic block 2 of hypotenuse to position sealing by magnetic in fan-shaped chute.
In use, two edge fits will separate after the external diameter of piston ring 1 is worn, it is big that seam becomes, the magnetic block of installing respectively in seam space up and down 2 is at gas pressure and act under the pressure of piston ring internal diameter separately toward opposite direction slipper seal wearing and tearing interface, prevent gas leakage, two-way envelope gas is realized whole circulation process envelope gas.
Be illustrated in figure 2 as magnetic block 2 since gas pressure to piston ring radial direction slipper seal wearing and tearing interface.
Be illustrated in figure 3 as magnetic block 2 since act on the piston ring internal diameter pressure and to piston ring opposite direction slipper seal wearing and tearing interface radially.
Claims (2)
1, a kind of magnetic automatic sealing piston ring, the seam of its piston ring (1) is for taking mouth structure up and down, it is characterized in that at each edge fit of taking mouthful seam crossing up and down be hypotenuse, form two radially opposite splayed joint spaces up and down at seam crossing, be separately installed with magnetic block (2) in seam space up and down, two limits of magnetic block (2) and the edge fit of piston ring (1) join.
2, magnetic automatic sealing piston ring according to claim 1 is characterized in that being hypotenuse at two edge fits taking mouthful seam crossing up and down, and two hypotenuses of magnetic block (2) and two hypotenuses of piston ring (1) join.
