Abstract
The utility model discloses an irregular sealing ring, which is especially suitable for sealing surfaces of various mechanical rotating axle heads and comprises a ring body. The utility model is characterized in that the centre of the ring body is a deformed cavity; at least one layer of reinforcing ribs are combined in the ring body; four corners of the cross section of the ring body are provided with auxiliary sealing petals. The hollow sealing ring is adopted, the reinforcing ribs are additionally arranged in the ring body, and four upper and lower corners of the ring body are provided with the auxiliary sealing petals, so the sealing ring has the advantages of high durability, strong elastic capacity of compensation and two-way sealing compensation in positive-negative pressure.
Description
Technical field:
The utility model relates to mechanical sealing element, particularly a kind of special-shaped seal ring that uses on the various mechanical rotation spindle nose sealing surfaces that is applicable to.
Background technique:
At present, the Sealing that uses on the mechanical rotation sealing surface is solid filler both at home and abroad, as rubber seal ring, nylon ring, packing rope etc., this traditional Sealing is because the elastic compensating of material itself is limited in one's ability, under positive negative pressure condition, Sealing is subjected to the burn into friction of medium and the influence of sealing surface precision, often causes dielectric leakage, not only delays production, also pollute the environment, application area is limited.
Summary of the invention:
The purpose of this utility model is that a kind of elastic compensating ability of design is strong, sealability reliable, the special-shaped seal ring of applied range.
The technical solution of the utility model is finished as follows, and it includes a ring body, it is characterized in that: the ring body center is a distortion cavity, is compounded with one deck stiffening rib at least in the ring body, and four jiaos of the ring body cross section have the secondary seal lobe.The secondary seal lobe height of both sides is slightly given prominence to lower camber side on the ring body up and down.The utility model is owing to adopt hollow seal ring, and set up stiffening rib in ring body, simultaneously ring body up and down four jiaos the secondary seal lobe is set respectively, so, that the sealing ring has is durable, the elastic compensating ability is strong, can play two way sealed compensation, advantage applied widely in positive negative pressure.
Description of drawings:
Fig. 1 is a cross-sectional view of the present utility model.Among the figure, 1. secondary seal lobe, 2. ring body, 3. stiffening rib, 4. distortion cavity.
Embodiment:
Special-shaped seal ring of the present utility model includes a ring body 2, and the ring body center is a distortion cavity 4, is compounded with one or more layers stiffening rib 3 in the ring body, and four jiaos of the ring body cross section are respectively equipped with secondary seal lobe 1.The secondary seal lobe height of both sides is slightly given prominence to lower camber side on the ring body up and down, and the optimum angle of inside and outside two secondary seal lobes is the 60-80 degree.Ring body material of the present utility model can be selected a year alkaline-resisting rubber manufacturing, also available soft pvc or CABLE MATERIALS manufacturing for use.Stiffening rib can be selected cord fabric or tyre cord for use.The utility model strengthens the elastic compensating ability of ring body owing to adopt hollow seal ring significantly, has set up stiffening rib in ring body, make seal ring more durable, ring body up and down four jiaos the secondary seal lobe is set respectively, when positive negative pressure, play the two way sealed compensating action, applied widely.
