Description
Technical Field
The utility model relates to the technical field of sealing elements, in particular to a composite sealing ring.
Background
The sealing ring belongs to an essential sealing part in machining equipment, the sealing ring, the sealing strip or the sealing gasket are arranged between the connecting end surfaces of the two connecting parts, and the sealing ring is deformed by utilizing the axial compression mode of the two connecting parts to form elastic fit between the sealing ring and the connecting ends of the two connecting parts, so that solvents such as lubricating oil, gas and the like in the sealing ring cannot leak or leak from the connecting ends of the parts;
however, the conventional planar sealing ring is of a single sheet-shaped structure and has no steps, so that when the end cover on some mechanical equipment operating at high speed is sealed, thin lubricating oil leakage caused by internal temperature rise is often avoided, and the end cover is often screwed down by a screw for fixedly mounting the end cover at high moment, so that the end cover generates larger axial locking force to strongly press the sheet-shaped sealing ring, and large deformation is generated, thereby forming a potential safety hazard that the sealing ring is deformed greatly for a long time to cause plastic deformation of an internal structure, and further the service life is shortened.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems and provides a composite sealing ring which comprises a composite sealing ring body, wherein the composite sealing ring body is formed by combining a sealing ring and an elastic ring arranged in the sealing ring, an open slot is formed in the end surface of the sealing ring body, a convex sealing step is formed in the other end surface of the sealing ring body, the two sides of the sealing step correspond to those of the open slot, the elastic ring formed by butting two heads of a ring-shaped spring is embedded into the open slot, and the highest point of the circumference of the elastic ring is not higher than the upper opening position of the open slot.
The utility model achieves the aim through the following technical scheme, and the composite sealing ring comprises a composite sealing ring body, wherein the composite sealing ring body is formed by combining a sealing ring and an elastic ring arranged in the sealing ring;
the sealing ring is internally provided with a through hole, the end surface of the main body is provided with an open slot, and the other end surface of the main body is provided with a convex sealing step;
the elastic ring is formed by butting two heads of a ring-shaped spring, and the elastic ring is embedded into the open slot.
Further, the width and the depth of the open groove are consistent with the diameter of the elastic ring.
In a further arrangement, the port of the sealing step is semi-circular.
Further, the center lines of the sealing step and the opening groove are overlapped.
Further, after the elastic ring is embedded into the open slot, the highest point of the circumference of the elastic ring is not higher than the upper opening of the open slot.
The utility model has the beneficial effects that:
the stepped structure can effectively seal the joint point of the two components in a radial and end face compression manner, and the elastic ring can elastically buffer the degree of end face compression, so that the problem of shortened service life caused by excessive deformation of the end face of the sealing ring due to compression is avoided.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Fig. 2 is an exploded schematic view of fig. 1.
In the figure: the composite sealing ring comprises a composite sealing ring body 1, a sealing ring 2, a main body 201, an opening groove 202, a sealing step 203, a through hole 204 and an elastic ring 3.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the protection scope of the present invention.
As shown in fig. 1 and 2, a composite seal ring is a composite seal ring body 1 composed of a seal ring 2 and an elastic ring 3 installed in the seal ring 2, an open slot 202 is arranged on the end surface of a main body 201 of the seal ring 2, a convex sealing step 203 is arranged on the other end surface, the sealing step 203 corresponds to the two sides of the open slot 202, the elastic ring 3 formed by butting two heads of a ring-shaped spring is embedded into the open slot 202, and the highest point of the circumference of the elastic ring 3 made of spring steel is not higher than the upper opening position of the open slot 202.
In the application implementation, establish an open slot that corresponds with sealed step 203 at the connection terminal surface of end cover, the sealed step 203 of sealing washer 2 is packed into in the open slot of end cover, and the terminal surface laminating of 2 medial surfaces of sealing washer and end cover, when the installation is fixed, along with the tightening process of fixed screw, the terminal surface interval of end cover and cylinder reduces gradually, after compound sealing washer body 1 elastic compression in the middle of synchronous deformation to certain range, the elastic property of the spring steel of elastic ring 3 in the open slot 202 produces elastic resistance automatically, remind the elastic compression range of sealing washer body 1 to arrive suitable degree, under the prerequisite that reaches sealing performance, make compound sealing washer body 1 reach the effective deformation when installing and using.
Composite seal circle body 1 is in sealed application, from the sealed dual leakproofness of radial embedded sealed, axial pressing mode, the effectual sealing performance who promotes under the equipment abnormal conditions, and the locking of elastic ring 3 is reminded simultaneously and is made composite seal circle body 1's elasticity compression degree suitable, avoids because of drawback and the hidden danger that excessive deformation leads to life to shorten.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it is therefore intended that the present embodiments be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein without any reference thereto being intended to limit the claims to which they are entitled.
