The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art in a specific case.
The invention will be described in detail below with reference to the drawings in connection with embodiments.
As shown in fig. 1 and 2, the high-pressure-resistant shaft hole double-purpose sealing ring comprises a base body 1 with an annular structure, wherein a sealing lip 2 is arranged on one side of the base body 1, and a first sealing groove 3 for installing an O-shaped sealing ring is reserved on the other side of the base body; a second sealing groove 4 is reserved on the inner wall of the base body 1, and a metal ring 5 is arranged at a position, close to the first sealing groove, on the inner wall of the base body 1; the sealing lip 2 is of a U-shaped structure. The matrix is a rubber matrix, preferably oil-resistant rubber.
The first sealing groove 3 for installing the O-shaped sealing ring is reserved on one side of the base body 1, when the sealing ring is used for sealing by utilizing the end face of the sealing ring different from the side provided with the lip 2 (for example, when the sealing ring is combined with other sealing members for use, the side which is not provided with the lip 2 by utilizing the sealing ring is attached with the other sealing members to jointly form a combined sealing structure), the O-shaped sealing ring can be installed in the first sealing groove 3, and the sealing device is very convenient and practical, and ensures the tightness between sealing components used in combination.
The second sealing groove 4 is reserved on the inner wall of the base body 1, when the sealing device is used for shaft sealing, corresponding sealing elements (such as O-shaped sealing rings) can be installed in the second sealing groove to form a combined sealing structure, the sealing elements in the second sealing groove and the lips of the sealing rings can play a double sealing role, the sealing effect is excellent, and even if the sealing elements in the second sealing groove 4 are replaced after long-term use, the sealing effect can be better ensured, the sealing ring main body (the base body and the metal rings) are not required to be replaced, the material is saved, the practical cost is saved, and the difficulty of replacing sealing operation is reduced.
The first seal groove 3 has a dovetail structure as a whole, and the groove width thereof gradually increases from the opening position to the groove bottom. The structural design of the sealing groove effectively avoids the sealing piece from separating from the sealing groove. In addition, in order to ensure that the sealing element is tightly matched with the sealing groove and realize reliable sealing, the sealing element can be vulcanized and bonded in the sealing groove at the closed end of the valve core body when the sealing element is installed.
Typically, the groove width of the first seal groove 3 near the groove bottom is 1.2 to 1.5 times the groove width near the opening position. At this width ratio, it can be better ensured that the sealing member (typically an O-ring) is pressed to fill the first seal groove 3, and the overall stability is better and the sealing is reliable. The sealing element is pressed and then integrally extruded into the first sealing groove, so that the tightness is not affected.
The metal ring 5 is a copper ring, the thickness of which is 3-8mm and the width of which is 10-15mm. In general, one end of the metal ring is flush with the end face of the side where the lip is not arranged, namely, the metal ring 5 is installed on the inner wall of the base body from one side of the base body, a groove 6 is formed in the position of the inner wall of the base body for installing the metal ring, and the inner diameter of the installed metal ring is consistent with that of the inner wall of the base body. The base body plays a sealing role, the metal ring can play an excellent supporting and positioning role, a certain abrasion-resistant protection role is formed on the base body, and the sealing ring is applicable to long-term use under high-speed and heavy-load working conditions and cannot be worn too early.
The outer wall surface of the base body 1 is provided with a wear-resistant layer. Typically, the wear-resistant layer comprises a wear-resistant mesh formed by interlacing a plurality of fiber threads, and a rubber paddle coated on the wear-resistant mesh.
The invention has compact structure and strong pressure resistance, can be suitable for the working conditions of high pressure, high speed and heavy load, has excellent sealing capability, can be combined with other sealing elements for use, and achieves good sealing effect. Meanwhile, the sealing ring can be used as a shaft sealing piece or a hole sealing piece, and is very good in universality.
The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
