Description
Technical Field
The utility model relates to a general stopper seals sealing washer technical field, concretely relates to exempt from general stopper sealing washer of rubber of spring.
Background
The flooding plug Seal (Spring Seal/Spring energized Seal/valve Seal) is a high-performance Seal with special Spring in U-shaped Teflon, and by adding proper Spring force and system fluid pressure, the sealing lip (surface) is ejected to lightly press the sealed metal surface to generate excellent sealing effect. The spring actuation effect can overcome slight eccentricity of the metal mating surfaces and wear of the sealing lips, while continuing to maintain the desired sealing performance. The flood seal can be made in accordance with AS568A standard O-ring grooves (e.g., radial shaft seal, piston seal, axial face seal, etc.) and can completely replace the universal O-ring.
However, the conventional flooding plug seal is easy to be immersed in liquid and corrode a spring in the flooding plug seal in the using process, so that the service life of the flooding plug seal is shortened.
Disclosure of Invention
In order to overcome the shortcoming and the deficiency that exist among the prior art, the utility model aims to provide an exempt from general stopper sealing washer of rubber of spring has avoided general stopper to seal the spring that uses and has corroded and reduce the life who fills up broadly and seal.
The purpose of the utility model is realized through the following technical scheme: the utility model provides a rubber of exempting from spring fills up sealing washer entirely, seals the body and blocks the elastic rubber circle of locating general stopper and sealing the body including general stopper, general stopper seals the body and is the annular, the ring groove has been seted up at the top of general stopper seal body, the elastic rubber circle card is located ring groove's inner wall stretches out suddenly the top of general stopper seal body, the both sides wall at ring groove's top respectively with the elastic rubber circle stretches out suddenly the both ends butt of general stopper seal body.
Preferably, the bottom caliber of the ring-shaped clamping groove is smaller than the top caliber of the ring-shaped clamping groove.
Preferably, the bottom of the elastic rubber ring is provided with a guide pin which is abutted against the inner wall of the annular clamping groove.
Preferably, the bottom of the inner side wall of the guide pin and the bottom of the outer side wall of the guide pin are both arc-shaped.
Preferably, the bottom of the flooding plug seal body and the inner side wall of the flooding plug seal body are in rounded transition.
The beneficial effects of the utility model reside in that: the utility model discloses a spring-free rubber universal plug sealing ring, the elastic rubber circle with the help of self elasticity effect joint in the ring groove of universal plug sealing body and play the effect of buffering, reinforcement support, the equipment is convenient, the elastic rubber circle provides initial pretightning force for the rubber universal plug sealing ring, and can bear the deflection of hydraulic cylinder's axis, improve the rubber universal plug sealing ring seal effect and seal stability, because the both ends butt that the both ends of ring groove's top suddenly stretched out universal plug sealing body with the elastic rubber circle respectively, make ring groove form the enclosure space, thereby avoid liquid infiltration ring groove in and reduce seal stability; compare with traditional general stopper seal, the utility model discloses a rubber general stopper sealing washer has avoided using the spring and has received liquid corrosion damage and lead to general stopper seal's sealed effect to reduce, life reduces.

Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and accompanying drawings, which are not intended to limit the present invention.
As shown in fig. 1-3, a rubber stopper sealing washer that floods of spring exempts from, seal body 1 and the elastic rubber who blocks and seal body 1 including the general stopper and locate the elastic rubber circle 2 that floods the stopper and seal body 1, general stopper seals body 1 and is the annular, ring groove 3 has been seted up at the top that floods the stopper and seals body 1, elastic rubber circle 2 blocks and locates ring groove 3's inner wall and the salient stretch out floodplug seals the top of body 1, the both sides wall at ring groove 3's top respectively with elastic rubber circle 2 salient stretch out floodplug seals the both ends butt of body 1.
In the embodiment, the elastic rubber ring 2 is clamped in the annular clamping groove 3 of the flooding plug seal body 1 under the action of self elasticity and plays roles of buffering and reinforcing support, the assembly is convenient, the elastic rubber ring 2 provides initial pretightening force for the rubber flooding plug seal ring and can bear the deflection of a middle shaft of a hydraulic oil cylinder, the sealing effect and the sealing stability of the rubber flooding plug seal ring are improved, and the two side walls at the top of the annular clamping groove 3 are respectively abutted against the two ends of the elastic rubber ring 2 which protrudes out of the flooding plug seal body 1, so that the annular clamping groove 3 forms a closed space, and the phenomenon that liquid permeates into the annular clamping groove 3 to reduce the sealing stability is avoided; compare with traditional general stopper seal, the utility model discloses a rubber general stopper sealing washer has avoided using the spring and has received liquid corrosion damage and lead to general stopper seal's sealed effect to reduce, life reduces. Furthermore, the cross section of the elastic rubber ring 2 is approximately in a T shape, the elastic rubber ring 2 comprises a ' -shaped ring and an I-shaped ring connected with the ' -shaped ring, a chamfer 4 is arranged between the ' -shaped ring and the I-shaped ring, the chamfer 4 is abutted against the top of the annular clamping groove 3, and the elastic rubber ring 2 is of an integrally formed structure.
In this embodiment, the bottom caliber of the ring slot 3 is smaller than the top caliber of the ring slot 3.
By adopting the technical scheme, on one hand, the annular clamping groove 3 clamps the elastic rubber ring 2 to prevent the elastic rubber ring 2 from separating from the flooding plug sealing body 1; on the other hand, when the in-service use, the axis of external hydraulic oil pump runs through the middle part of general stopper seal body 1 (the hollow round hole in annular general stopper seal body 1 middle part promptly) and supports and lean on in the inside wall of general stopper seal body 1, and the lateral wall of general stopper seal body 1 closely supports with the sealing groove face of hydraulic oil pump and leans on, and the effect that annular groove 3 combines 2 cushions of elastic rubber circle, reinforcement to support improves sealed effect jointly. Further, the cross section of ring groove 3 is roughly "V" type or is the isosceles trapezoid shape of invering, ring groove 3's bore reduces from top to bottom gradually, chamfer 4 supports with ring groove 3's top and leans on, and when pressurized, thereby chamfer 4 cushions the compressive force that general stopper seals body 1 and receive with the help of the elastic force effect of self.
In this embodiment, the bottom of the elastic rubber ring 2 is provided with a guide pin 5, and the guide pin 5 abuts against the inner wall of the annular clamping groove 3.
Adopt above-mentioned technical scheme, be convenient for go into elastic rubber circle 2 card in ring groove 3, make elastic rubber circle 2 be absorbed in ring groove 3's depths, improve elastic rubber circle 2 and general stopper and seal the fastening nature of being connected of body 1, improve the packaging efficiency.
In this embodiment, the guide pin 5 is annular, and the bottom of the inner sidewall of the guide pin 5 and the bottom of the outer sidewall of the guide pin 5 are both arc-shaped.
Adopt above-mentioned technical scheme, be convenient for go into elastic rubber circle 2 card in ring groove 3, make elastic rubber circle 2 be absorbed in ring groove 3's depths, improve elastic rubber circle 2 and general stopper and seal the fastening nature of being connected of body 1, improve the packaging efficiency.
In the present embodiment, the bottom of the flooding plug seal body 1 and the inner side wall of the flooding plug seal body 1 are in rounded transition.
