Abstract
The utility model provides a sealed pad of magnetic force of being applied to conveying line, including locating washers (1), the shaping is gone up in locating washers (1) has a plurality of to run through, arc slotted hole (11) of lower terminal surface, it has curved go up magnet piece (2) and lower magnet piece (3) to peg graft in arc slotted hole (11) of locating washers (1), upward repel each other magnet piece (2) and lower magnet piece (3), it fixes on upper antiextrusion ring (4) to go up magnet piece (2), magnet piece (3) are fixed in lower check ring (5) down) on, lower check ring (5), cladding rubber sleeve (6) are gone up in upper antiextrusion ring (4) and locating washers (1). Its simple structure sets up the elastic construction that magnet repels each other in the rubber pad to sealed effect in the reinforcing rubber pad, the phenomenon that the emergence was leaked thereby reducible rubber pad became invalid.
Description
Technical field：
This utility model is related to the technical field of seal connector, more specifically to a kind of transfer pipeline that is applied to
Magnetic seal pad.
Background technology：
At present in some chemical industry, the industry of pharmacy, its medicinal liquid is conveyed by pipeline, and its pipeline is generally and splices
Pipeline, the mouth of pipe of its pipeline forms flange, thus being attached by bolt assembly, and in order to ensure between pipeline
Sealing, can add rubber washer between the flanges；And rubber washer is subject to such environmental effects very big, appearance of being such as heated is shunk, and goes out
The flange of existing rubber washer and pipeline is not fitted, then be easy for leaking.
Utility model content：
The purpose of this utility model is aiming at the deficiency of prior art, and provides a kind of magnetic being applied to transfer pipeline
Power sealing gasket, it can increase the sealing property of sealing rubber pad, reduces the generation of leakage.
A kind of magnetic seal pad being applied to transfer pipeline, including space washer, space washer forms several and passes through
Put on, the arc-shaped slot of lower surface, be plugged with upper magnet block and the lower magnet block of arc, upper magnetic in the arc-shaped slot of space washer
Iron block and lower magnet block repel each other, and upper magnet block is fixed on back-up ring, and lower magnet block is fixed on lower back-up ring, lower back-up ring, upper gear
Rubber sleeve is coated on circle and space washer.
The rectangular in cross-section of described rubber sleeve, rubber sleeve is non-enclosed sealing shroud, and the fluting on rubber sleeve is located at fixed
On the outer ring of position packing ring, space washer upper sleeve has lasso, is clamped between lasso and space washer at the fluting of rubber sleeve.
Described arc-shaped slot is ringwise evenly distributed on space washer, the upper magnet block in arc-shaped slot or lower magnet
The shape of block is identical with the shape of arc-shaped slot, and the magnetic pole of the upper magnet block both ends of the surface relative with lower magnet block is identical.
The thickness of described lower back-up ring and upper back-up ring is equal, and the diameter of lower back-up ring or upper back-up ring inner ring is equal to space washer inner ring
Diameter, the diameter of lower back-up ring or upper back-up ring outer ring is equal to the diameter of space washer outer ring.
The beneficial effects of the utility model are：
It arranges the elastic construction that Magnet repels each other in rubber blanket, to strengthen the sealing effectiveness in rubber blanket, thus can subtract
Few rubber blanket lost efficacy and the phenomenon of leakage occurred.

Specific embodiment：
Embodiment：As shown in Fig. 1 to 3, a kind of magnetic seal pad being applied to transfer pipeline, including space washer 1, position
The arc-shaped slot 11 that several run through upper and lower end face is formed on packing ring 1, in the arc-shaped slot 11 of space washer 1, is plugged with arc
The upper magnet block 2 of shape and lower magnet block 3, upper magnet block 2 and lower magnet block 3 repel each other, and upper magnet block 2 is fixed on back-up ring 4, under
Magnet piece 3 is fixed on lower back-up ring 5, and lower back-up ring 5, upper back-up ring 4 and space washer 1 coat rubber sleeve 6.
The rectangular in cross-section of described rubber sleeve 6, rubber sleeve 6 is non-enclosed sealing shroud, and the fluting on rubber sleeve 6 is located at
On the outer ring of space washer 1, space washer 1 upper sleeve has lasso 7, is clamped in lasso 7 and space washer at the fluting of rubber sleeve 6
Between 1.
Described arc-shaped slot 11 is ringwise evenly distributed on space washer 1, the upper magnet block 2 in arc-shaped slot 11 or
The shape of lower magnet block 3 is identical with the shape of arc-shaped slot 11, the magnetic pole of upper magnet block 2 both ends of the surface relative with lower magnet block 3
Identical.
The thickness of described lower back-up ring 5 and upper back-up ring 4 is equal, and the diameter of lower back-up ring 5 or upper back-up ring 4 inner ring is equal to space washer
The diameter of 1 inner ring, the diameter of lower back-up ring 5 or upper back-up ring 4 outer ring is equal to the diameter of space washer 1 outer ring.
Operation principle：This utility model is magnetic seal pad, its actually internal rubber gasket setting up magnet arrangement, its
The rubber sleeve 6 of outer layer is continuingly acted on by the repel each other active force of generation of upper magnet block 2 and lower magnet block 3, such as rubber sleeve 6 is heated
Shrink lower thickness, under usual condition, between rubber sleeve 6 and connector, gap occurs, be susceptible to leak, and this magnetic force is close
Packing, above rubber sleeve 6 is stretched by back-up ring 4 and lower back-up ring 5 for magnet piece 2 and lower magnet block 3 promotion thereon, so that rubber sleeve 6 is originally received
The outer surface of contracting continues to be fitted and connected part, it is to avoid leak.
