Abstract
The utility model relates to a sealing ring with multiple sealing channels. The sealing ring comprises a sealing ring body (1), an annular boss (2), elastic bending portions (3), a sealing ring A (4) and a sealing ring B (5). The annular boss (2) is disposed in the middle of the outer wall of the sealing ring body (1). The sealing ring body (1) and the annular boss (2) are molded to be a whole structure. The elastic bending portions (3) are symmetrically arranged on upper and lower ends of the inner side of the sealing ring body (1). Each elastic bending portion (3) extends toward the middle of the sealing ring body (1). A compensation spring (6) is placed to the inner side of each elastic bending portion (3). The outer wall of the annular boss (2) is equipped with an arc groove A (7), and the sealing ring A (4) is put into the arc groove A (7). The inner wall of the sealing ring body (1) is provided with an arc groove B (8), and the sealing ring B (5) is put into the arc groove B (8). The sealing ring with multiple sealing channels has the advantages of having a good sealing effect and being long in service life.
Description
Technical field
The utility model relates to seal ring technical field, and particularly a kind of have a multiple-sealed seal ring.
Background technique
Seal ring in the course of the work, except bearing the factors such as working temperature, pressure, corrosion, also need the friction pair end face friction of bearing due to seal ring to produce certain temperature simultaneously, thereby aggravated the wearing and tearing of the friction pair end face of seal ring, and then affected sealing effect and the working life of seal ring.
In mechanical system, seal arrangement is very important constituent element, under many circumstances, sealability will directly affect service behaviour and the quality of whole system, seal ring is generally used on the junction surface of the link of establishing stream in two, when seal ring is installed, need to be by seal ring inlay card in the adjacent groove that needs sealed connection part, then by bolt etc., two parts are connected, the sealing that keeps two links by seal ring, but such seal ring is easy to drop out when internal high pressure, and easily dislocation when mounted, cause sealing influenced, also may the internal flow path of link be formed and be disturbed simultaneously, give to install and use and bring very big inconvenience.
Existing seal ring seal ring when work directly contacts with the material of outside required isolation, particularly there is the medium that corrosivity is larger, easily corrode seal ring, affect sealing effect, when safeguarding, changing seal ring frequency increases, and the frequency of dismounting seal ring also promotes thereupon, causes decline the working life of seal ring.
Model utility content
The purpose of this utility model is to overcome the shortcoming of prior art, provides having of a kind of good sealing effect and long service life multiple-sealed seal ring.
The purpose of this utility model is achieved through the following technical solutions: a kind of have a multiple-sealed seal ring, it comprises seal ring body, annular boss, elastic deflection portion, seal ring A and seal ring B, the outer wall middle part of described seal ring body is provided with annular boss, seal ring body and the annular boss structure that is formed in one, the two ends up and down of seal ring body inner side are symmetrically arranged with elastic deflection portion, elastic deflection portion extends to the middle part of seal ring body, and the inner side of elastic deflection portion is filled with counterbalance spring; On the outer wall of annular boss, offer arc groove A, seal ring A is seated in arc groove A; On the inwall of seal ring body, also offer arc groove B, seal ring B is seated in arc groove B.
Described arc groove A and arc groove B are positioned in same level.
Described seal ring A and seal ring B are silicone rubber O-ring.
The utlity model has following advantage:
1, in inner side and the outside of seal ring, sealing configuration is all set, and on the inwall of seal ring, the spring with compensation sealing function is set, sealability is more excellent, improves the stability of seal ring work.
2, at seal ring inwall, elastic deflection portion is set; and at elastic deflection portion inner side filling counterbalance spring, making seal ring in the course of the work, its internal surface forms seal space with main shaft all the time; effectively protection seal ring B is not subject to external interference, is conducive to the working life of lift-off seal ring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A sectional structure schematic diagram in Fig. 1;
In figure: 1-seal ring body, 2-annular boss, 3-elastic deflection portion, 4-seal ring A, 5-seal ring B, 6-counterbalance spring, 7-arc groove A, 8-arc groove B.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As depicted in figs. 1 and 2, a kind of have a multiple-sealed seal ring, it comprises seal ring body 1, annular boss 2, elastic deflection portion 3, seal ring A4 and seal ring B5, the outer wall middle part of described seal ring body 1 is provided with annular boss 2, seal ring body 1 and annular boss 2 structure that is formed in one, the two ends up and down of seal ring body 1 inner side are symmetrically arranged with elastic deflection portion 3, and elastic deflection portion 3 extends to the middle part of seal ring body 1, and the inner side of elastic deflection portion 3 is filled with counterbalance spring 6; On the outer wall of annular boss 2, offer arc groove A7, seal ring A4 is seated in arc groove A7; On the inwall of seal ring body 1, also offer arc groove B8, seal ring B5 is seated in arc groove B8.
Further, described arc groove A7 and arc groove B8 are positioned in same level.
Further, described seal ring A4 and seal ring B5 are silicone rubber O-ring, have good corrosion-resistant, heat-resisting, cold-resistant, resistance to ozone, resistance to weathering energy.
Under the elastic reaction of counterbalance spring 6, make elastic deflection portion 3 all the time with main shaft close contact; elastic deflection portion 3 forms confined space with main shaft; effectively protect seal ring B5 not to be subject to the interference of extraneous medium, effectively extend the working life of seal ring B5, and then extend the working life of seal ring.
Claims (3)
