Abstract
The utility model relates to the field of sealing, in particular to an O-type sealing ring, which comprises an O-type sealing ring body. The cross section of the body is round, and a ring of water-proof ring sheets are arranged on the outer lateral side of the body along the circumferential direction. The thickness of the water-proof ring sheets is 10%-30% of the diameter of the cross section of the body, and the width of the water-proof ring sheets is 0.5-2 times of the diameter of the cross section of the body. The water-proof ring sheets are arranged at any position between 1/2 of the body in axial direction and 1/4 of the body in axial direction, and the water-proof ring sheets and the body are formed in integral mode. The water-proof ring sheets are added on the sealing ring body, arranged above or under the widest position of the outer diameter of the body and can compensate deformation generated by the sealing ring body during vibration of equipment, thereby enhancing dust-proof and water-proof effects based on original sealing.
Description
Technical field
The utility model relates to field of sealing technology, particularly a kind of O-ring seals.
Background technique
In equipment such as various machineries, chemical industry, metallurgy and pharmacy,, effective seal need be provided between equipment interface in order to prevent the seepage of liquids and gases.For this reason, generally adopt various seal rings as seal element.The section of existing rubber o-ring is simple round structure basically, and is as depicted in figs. 1 and 2.Surface of contact is dustproof under connection sealing service condition, waterproofing effect is not good for it, is prone to cause that sealing effect descends.Simultaneously, when equipment uses, can produce vibration usually, the vibration of equipment will make seal ring generation deformation, thereby influence sealing effect.
The model utility content
The technical problem that the utility model will solve is: surface of contact is dustproof in order to overcome, the not good deficiency that causes that easily sealing effect descends of waterproofing effect, and the utility model provides a kind of O-ring seals dustproof, waterproofing effect that improves.
The utility model solves the technological scheme that its technical problem adopted: a kind of O-ring seals, comprise the O-ring seals body, and the cross section of body be circular, circumferentially has one at the outer side surface of body and encloses the waterproof ring plate.
For guarantee to prevent dust, waterproofing effect and can normally assembling, the thickness of described waterproof ring plate be body diameter of section 10%～30%, width is 0.5～2 times of diameter of section of body.
In order to guarantee that waterproof ring sheet after the seal ring body generation deformation can play the effect of compensation sealing, described waterproof ring plate is positioned at body shaft to the arbitrary position of 1/2 place to body shaft to 1/4 place.
In order to guarantee sealing effect and to be convenient to processing, described waterproof ring plate and this body by integral forming.
The beneficial effect of the utility model is; The utility model O-ring seals; On the seal ring body, increase the waterproof ring plate; And the waterproof ring plate be positioned at this body diameter the widest position above or below, the deformation that the waterproof ring plate can compensation sealing circle body produces when vibration equipment, thus on the basis of original sealing, strengthened dustproof, waterproofing effect.

Fig. 4 is the B-B sectional view of Fig. 3.
Fig. 5 is the partial enlarged drawing at M place among Fig. 4.
Among the figure 1, body, 2, the waterproof ring plate.
Embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Like Fig. 3, Fig. 4, shown in Figure 5, a kind of O-ring seals comprises O-ring seals body 1, and the cross section of body 1 is circular, circumferentially has a circle and body 1 integrated waterproof ring plate 2 at the outer side surface of body 1.The thickness of waterproof ring plate 2 be body 1 diameter of section 10%～30%, width be body 1 diameter of section 50%.Waterproof ring plate 2 is positioned at body 1 axial 1/4 place; Produce for ease, waterproof ring plate 2 is easy-formation at axial 1/2 place.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
