Abstract
The utility model discloses a rubber sealing ring for a valve. The rubber sealing ring mainly comprises a frame (2) with a through hole (1), and a rubber collar (3) which is arranged in the through hole (1) and is bonded on the frame (2). The rubber sealing ring is characterized in that the inner wall of the mouth of the rubber collar (3) is provided with more than one annular groove (4), and meanwhile elastic rubbers (5) are filled in the annular grooves (4). The elastic rubbers and the rubber collar are used together for valve sealing, so that the rubber sealing ring has high strength and achieves remarkable sealing effect.
Description
Technical field
The utility model relates to a kind of seal ring, specifically is meant a kind of valve rubber seal.
Background technique
Valve often all will seal its bearing in its actual application process as industrial widely used product, thereby guarantees the sealing effect of this valve.The sealing means that present people are adopted is upper and lower two seal rings that are made of plastics of the bearing upper ring cap that seals at needs, just can rub with the hands when this upper and lower seal ring is stressed and hold interlock, and then realize the function of sealing, and its structure as shown in Figure 1.But, adopt this sealing means not only to need to expend a large amount of plastics, make that its fabricating cost is higher, and its sealing effect is also undesirable, can not satisfy actual application demand.
Summary of the invention
The purpose of this utility model is to overcome fabricating cost higher, the sealing effect unfavorable defective of present valve with seal ring, provide a kind of not only simple in structure, and fabricating cost is cheap, the valve rubber seal of sealing effect highly significant.
The purpose of this utility model is achieved through the following technical solutions: the valve rubber seal, mainly by the skeleton that is provided with through hole and be arranged at this through hole rubber neck inner and that be bonded on the skeleton and form, also be filled with elastomer rubber simultaneously at the annular groove that is provided with on the collar extension inwall of rubber neck more than one, and in the inside of this annular groove.
The cross section of described annular groove is " V " font.
The utility model is compared than prior art, has the following advantages and beneficial effect:
(1) the utility model adopts elastomer rubber and rubber neck to come jointly valve is sealed, so its product strength is higher, the sealing effect highly significant.
(2) the utility model preparation process is comparatively simple, and fabricating cost is comparatively cheap.
Description of drawings
Fig. 1 is the existing structural representation that adopts rubber seal to seal.
Overall structure schematic representation when Fig. 2 is " V " font for annular groove cross section of the present utility model.
Fig. 3 is the structural representation of the utility model skeleton.
Embodiment
Below in conjunction with embodiment the utility model is described in further detail, but mode of execution of the present utility model is not limited thereto.
Embodiment
As shown in Figure 1, existing plastic seal ring is made up of last seal ring 6 and lower seal 7, and in order to ensure using effect, surface of contact of seal ring 6 and lower seal 7 is equipped with the groove of " V " font on this.During use, should go up seal ring 6 and lower seal 7 and directly be enclosed within on the valve shaft, and push under the effect of external force when being somebody's turn to do seal ring 6 and lower seal 7, whole seal ring just can be held in stressed stranding, thereby make the interlock of meeting of corresponding " V " font groove, and then realize sealing function.
The utility model has the skeleton 2 of through hole 1 by inside and is made up of the rubber neck 3 that rubber material is made.Wherein, the global shape of skeleton 2 is made and is circular, and its structure as shown in Figure 3.In order to satisfy the demand of different levels, this skeleton 2 both can be made metal frame by metallic material such as iron, copper, aluminum alloys, also can become plastic skeleton by plastic production.
The inside of described rubber neck 3 is provided with a through hole (also claiming collar extension), and the diameter of the diameter of this through hole and the valve shaft that will seal is complementary, and makes rubber neck 3 to be enclosed within on the valve shaft.This rubber neck 3 is positioned at through hole 1 inside of skeleton 2, and its outer ledge directly vulcanizes two end faces up and down at skeleton 2, thereby guarantees that rubber neck 3 directly is bonded on the skeleton 2, makes it form an integral body.
In order to increase sealing effect, the thickness at these rubber neck 3 collar extension places is greater than the thickness at rubber neck 3 outer ledge places.Simultaneously, the annular groove 4 that is parallel to each other more than also being provided with together on the collar extension inwall of this rubber neck 3 then is filled with the elastomer rubber of being made by the PVC plastics 5 in the inside of this annular groove 4.As required, the cross section of this annular groove 4 preferentially is made into " V " font shown in Figure 2.
As mentioned above, just can well realize the utility model.
Claims (2)
1. valve rubber seal, mainly by the skeleton that is provided with through hole (1) (2) and be arranged at this through hole (1) rubber neck (3) inner and that be bonded on the skeleton (2) and form, it is characterized in that: the annular groove (4) more than being provided with together on the collar extension inwall of rubber neck (3), simultaneously, also be filled with elastomer rubber (5) in the inside of this annular groove (4).
2. valve rubber seal according to claim 1 is characterized in that: the cross section of described annular groove (4) is " V " font.
