Abstract
The utility model discloses a sealer for an oil-water well, which includes a steel ring, wherein mounting grooves are arranged on both the upper and the lower end surfaces of the steel ring; an O-shaped seal ring is embedded in each mounting groove; the depth of the mounting groove is one second to two thirds of the thickness of the O-shaped seal ring; and chamferings are arranged on the outer edge and the inner edge of the steel ring. The sealer for the oil-water well has the following benefits: firstly, the structure is simple; and secondly, when seal is conducted specifically, the steel ring and the O-shaped seal ring are squeezed through steel hoops, so as to form a hard sealing surface between the steel hoop and the steel ring as well as form a soft sealing surface between the steel hoop and the O-shaped seal ring. As the leakage of the hard sealing surface can be sealed again through the soft sealing surface, the leakage problem can be radically solved.
Description
Technical field
The utility model relates to a kind of sealing device, particularly a kind of oil-water well sealer.
Background technology
At present, oil-water well connects the steel ring of usefulness, and its water injection pressure is bigger, generally can reach more than the 28Mpa, therefore, is easy to generate seepage, and seepage is easy to generate pollution again after producing, and therefore how to prevent the seepage of steel ring, is called a problem demanding prompt solution.In order to address this problem, people have taked to twine the mode of adhesive tape outside steel ring, but produce little effect, and still can not thoroughly solve leakage problems.
Summary of the invention
Problem to be solved in the utility model is: thus provide a kind of simple in structure, can form the oil-water well sealer that hard soft two sealing surfaces thoroughly avoid the seepage phenomenon to take place.
In order to solve the problems of the technologies described above, oil-water well sealer of the present utility model comprises steel ring, and described steel ring is equipped with a mounting groove on two end faces up and down, and described mounting groove is embedded with an O RunddichtringO.
For the ease of better the O RunddichtringO being pushed forming soft sealing face, oil-water well sealer of the present utility model, the degree of depth of described mounting groove is the 1/2-2/3 of O RunddichtringO thickness.
In order more closely steel ring to be pushed forming hard sealing surface, oil-water well sealer of the present utility model, the outward flange and the inward flange of described steel ring are equipped with chamfering.
The beneficial effect that the utility model is obtained is: (1) is simple in structure; When (2) specifically sealing, by stirrup steel ring and O RunddichtringO are pushed, thereby between stirrup and steel ring, form hard sealing surface, between stirrup and O RunddichtringO, form soft sealing face, and just because of the existence of soft sealing face, seepage to hard sealing surface is carried out shutoff again, thereby thoroughly solves leakage problems.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a scheme of installation of the present utility model.
Among the figure: 1, steel ring, 2, chamfering, 3, the O RunddichtringO, 4, mounting groove, 5, clip.
The specific embodiment
As shown in Figure 1, oil-water well sealer of the present utility model comprises steel ring 1, and described steel ring is equipped with a mounting groove 4 on two end faces about in the of 1, and described mounting groove 4 is embedded with an O RunddichtringO 3; The degree of depth of described mounting groove 4 is the 1/2-2/3 of O RunddichtringO 3 thickness; The outward flange of described steel ring 1 and inward flange are equipped with chamfering 2.
In the time of concrete the use, adjust clip, with clip 5 chucking steel ring 1 and O RunddichtringOs 3, at this moment, between the chamfering 2 of stirrup 5 and steel ring 1, form hard sealing surface, between stirrup 1 and O RunddichtringO 3, form soft sealing face, and just because of the existence of soft sealing face, seepage to hard sealing surface is carried out shutoff again, thereby thoroughly solves leakage problems.
Oil-water well sealer of the present utility model, the degree of depth of mounting groove 4 is the 1/2-2/3 of O RunddichtringO 3 thickness, thereby make 5 pairs of O RunddichtringOs 3 of stirrup to compress degree moderate, guaranteed the shut-off capacity of soft sealing face, solved leakage problems completely.
The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
