Abstract
The utility model belongs to the technical field of high-pressure pump sealing device manufacturing and particularly relates to a sealing ring of internal water cooling. The sealing ring comprises a sealing ring body. The internal ring periphery of the sealing ring body is provided with a cooling water channel. A ring-shaped supporting body is arranged in the cooling water channel. The sealing device is simple in structure. The cooling water channel is arranged in the sealing ring, so that the temperature of the sealing ring is lowered, the upper working pressure limit of the sealing ring is increased, and service life of the sealing ring is prolonged.
Description
Technical field
The utility model belongs to the seal arrangement manufacturing technology field of high-pressure service pump, relates in particular to a kind of seal ring with interior water-cooled.
Background technique
The seal ring using scope is wide, is widely used in the mechanical seal of every profession and trade, such as being arranged on the machinery such as oil-field oil pumper well head, pump, valve.
Existing seal ring is usually all shorter working life, if long-term the use, sealing effect can descend rapidly, can not reach seal request.Its reason mainly is:
1, existing seal ring is after long-term the use, be subject to wearing and tearing in various degree heating and shrink modification, cause the seal ring flexibility decrease and expansion power reduces, thereby can not inside and outside spreading, the original shape of seal ring and size be can't return to, effect and the effect of sealing finally can't be played.
2, also have a kind of by the up and down two seal rings that combine, this seal ring can inside and outside spreading by inclined-plane and opening after wearing and tearing, can return to original shape and size, yet, the two-piece concentricity of this seal ring is bad, whole unstable, cause stressed between part and part and wear and tear inhomogeneously, do not have effect and the effect of monolithic stability.
In sum, in fact be necessary to design a kind of also extraordinary Novel sealing ring of sealability that can use for a long time simultaneously, to overcome the defect of prior art.
The model utility content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of seal ring with interior water-cooled is provided, and reduces the seal ring heating, improves seal ring working life.
The utility model for achieving the above object, by the following technical solutions: a kind of seal ring with interior water-cooled, it is characterized in that: comprise the seal ring body, the inner loop week of described seal ring body is provided with cooling water passage, is provided with annular support in described cooling water passage.
Described seal ring body one side is provided with back-up ring, and this back-up ring is provided with intake tunnel and the exhalant canal that is communicated with described cooling water passage.
Beneficial effect: the utility model is simple in structure, and cooling water passage is set in seal ring, makes the temperature of seal ring reduce, and has improved the seal ring maximum working pressure, has extended its working life.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1, seal ring body; 2, cooling water passage; 3, annular support; 4, back-up ring; 5, intake tunnel; 6, exhalant canal.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1, a kind of seal ring with interior water-cooled, comprise seal ring body 1, the inner loop week of described seal ring body is provided with cooling water passage 2, be provided with annular support 3 in described cooling water passage, what this annular support can make plastic material can be also the converted steel material, select according to environment of living in, mainly play the effect of supporting cooling water passage, because this seal ring is to be applied in high-pressure service pump, therefore, annular support is selected the converted steel material, and the intake tunnel of cooling water passage and exhalant canal just are arranged on the seal ring body.Because most seal rings are all to be installed on fixing object, in the utility model, seal ring is installed on back-up ring, is provided with the intake tunnel 5 and the exhalant canal 6 that are communicated with described cooling water passage on this back-up ring.In the utility model, described seal ring caves inward and forms an annular inner groovy, the sealing effect of seal ring and better heat-radiation effect like this.
The utility model is simple in structure, and cooling water passage is set in seal ring, makes the temperature of seal ring reduce, and has improved the seal ring maximum working pressure, has extended its working life.
The above is only preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
1. seal ring with interior water-cooled, it is characterized in that: comprise the seal ring body, the inner loop week of described seal ring body is provided with cooling water passage, is provided with annular support in described cooling water passage.
2. the seal ring with interior water-cooled according to claim 1, it is characterized in that: described seal ring body one side is provided with back-up ring, and this back-up ring is provided with intake tunnel and the exhalant canal that is communicated with described cooling water passage.
