Abstract
The utility model relates to a high-pressure sealing ring. The high-pressure sealing ring comprises two single sealing ring bodies made of elastic rubber material, a mounting hole is formed in the middle of each single sealing ring body, the two single sealing ring bodies are connected into a whole, a plurality of cooling holes are formed in each single sealing ring body, and the cooling holes are evenly arranged in the circumferential direction of each single sealing ring body. According to the high-pressure sealing ring, the two single sealing ring bodies are connected into a whole to form the double-connecting-body sealing ring, and due to high-pressure pulses generated by pressure of a sealing system in the contact position between an end cover and the end face of a machine body, the single sealing ring body on the outer side can perform effective compensation sealing after the single sealing ring body on the inner side is damaged; meanwhile, due to the fact that the cooling holes are formed in the sealing ring, the cooling effect of the sealing ring can be improved, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of seal ring, relates in particular to a kind of high-pressure seal ring.
Background technique
In the end cap of the current high-pressure installation such as gear pump, vane pump and the sealing of body end face, the monomer seal rings that adopt more, because sealing medium produces high-voltage pulse under system pressure effect, impulsive force is easy to monomer seal ring to damage, if use two monomer seal rings, need on end cap or body, process the groove of two different sizes, thereby increase difficulty of processing and processing cost; In addition; Because the size difference of two monomer seal rings, also needs to use different moulds to produce, thereby easily causes the thickness size of two monomer seal rings to produce difference, affect sealing effect.And monomer seal ring time easily twists in assembling, also can affect sealing effect.The radiating effect of seal ring of the prior art is poor simultaneously, the working life of having reduced seal ring.
Model utility content
The utility model, in order to overcome deficiency of the prior art, provides a kind of high-pressure seal ring.
The utility model is to be achieved through the following technical solutions:
A kind of high-pressure seal ring, comprise two monomer seal ring bodies being made by elastic rubber material, the centre of described each monomer seal ring body has mounting hole, two described monomer seal ring bodies are connected as a single entity, on described monomer seal ring body, have some radiation holes, described radiation hole is circumferentially evenly arranged along monomer seal ring body.
As optimal technical scheme of the present utility model, sealing place of two described monomer seal ring bodies is circular arc.
As optimal technical scheme of the present utility model, described radiation hole is circular hole.
As optimal technical scheme of the present utility model, described radiation hole is square.
Compared with prior art, the beneficial effects of the utility model are: the utility model is by two monomer seal rings formation pair body-shaped sealing ring that is connected as a single entity, by the high-voltage pulse producing with its sealing system pressure of sealing place of the contact position of end cap and body end face, after the monomer seal ring of inner side damages, effectively compensation sealing of the monomer seal ring in outside; By offer radiation hole on seal ring, can improve its radiating effect simultaneously, increase the life-span.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model;
Fig. 2 is the A-A sectional view in Fig. 1.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1 and Fig. 2, Fig. 1 is plan view of the present utility model, and Fig. 2 is the A-A sectional view in Fig. 1.
Described a kind of high-pressure seal ring, comprise two monomer seal ring bodies 1 being made by elastic rubber material, the centre of described each monomer seal ring body 1 has mounting hole 2, two described monomer seal ring bodies 1 are connected as a single entity, on described monomer seal ring body 1, have some radiation holes 3, described radiation hole 3 is circumferentially evenly arranged along monomer seal ring body 1.Sealing place 4 of two described monomer seal ring bodies 1 is circular arc, and described radiation hole 3 is circular hole or square.
To sum up, the utility model is by two monomer seal rings formation pair body-shaped sealing ring that is connected as a single entity, by the high-voltage pulse producing with its sealing system pressure of sealing place of the contact position of end cap and body end face, after the monomer seal ring of inner side damages, effectively compensation sealing of the monomer seal ring in outside; By offer radiation hole on seal ring, can improve its radiating effect simultaneously, increase the life-span.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
