Abstract
The utility model relates to a plug, in particular to a double-sealed plug capable of being used on a transformer, a heat radiator and other devices. The plug comprises a plug seat and a countersunk bolt; the countersunk bolt passes through a threaded hole on the plug seat; a first sealing ring is arranged between the plug seat and the countersunk bolt; a shield for shielding the countersunk bolt is arranged on the plug seat and is in threaded connection with the plug seat; and a second sealing ring is also arranged between the shield and the plug seat. The shield is sleeved on the countersunk bolt; and the countersunk bolt inside the plug and the sealing rings are protected, thereby being not easy to damage and having long service. In addition, because the sealing ring is also arranged between the shield and the plug seat, the dual-sealed plug achieves the double-sealing function and has good sealing effect, thereby avoiding the occurrence of oil leakage.
Description
Technical field
The utility model relates to a kind of stopper, specifically is a kind of dual-seal stopper that can be used on the devices such as transformer, radiator.
Background technique
Power equipment such as transformer, be used on the header pipe of these parts such as fuel tank of radiator on the transformer and machinery and all need to install stopper, existing stopper mostly is that a countersunk screw is installed in the obturating plug of band counter sink, be provided with seal ring between obturating plug and the countersunk screw, prevent that inner oil leakage from going out.During oil plant, need turn on countersunk screw in periodic replacement, turn in a flash on the one hand, inside has a large amount of oil spurts and goes out, and is splashed to the operator or be difficult to control on the ground on one's body; On the other hand, countersunk screw and seal ring long term exposure are collided easily and are damaged outside, and seal ring is aging easily, causes the life-span to shorten greatly, and sealing effect is poor, and then need often to change seal ring, troublesome poeration.
The model utility content
The technical problems to be solved in the utility model is: troublesome poeration, problem such as sealing effect is poor, working life is short when overcoming existing stopper oil extraction provide a kind of dual-seal stopper.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of dual-seal stopper, have obturating plug and countersunk screw, countersunk screw penetrates in the tapped hole of obturating plug, be provided with first seal ring between obturating plug and the countersunk screw, obturating plug be provided with a guard shield that covers countersunk screw, guard shield is threaded with obturating plug, also is provided with second seal ring between guard shield and the obturating plug.
Described guard shield is shaped as hexahedron shape away from an end of obturating plug, is convenient to the installation and removal of obturating plug and guard shield.
The beneficial effects of the utility model are: be with guard shield on the countersunk screw, inner countersunk screw and seal ring are protected, and be not fragile, long service life; Seal ring is also arranged between guard shield and the obturating plug in addition, double seal, good sealing effect has been avoided the generation of oil leakage phenomenon.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Wherein: 1. obturating plug, 2. countersunk screw, 3. first seal ring, 4. guard shield, 5. second seal ring.
Embodiment
As shown in Figure 1, a kind of dual-seal stopper, have obturating plug 1 and countersunk screw 2, obturating plug 1 generally is installed on the header pipe as radiator, transformer etc., countersunk screw 2 penetrates in the tapped hole of obturating plug 1, be provided with first seal ring 3 between obturating plug 1 and the countersunk screw 2, obturating plug 1 is provided with a guard shield 4 that covers countersunk screw 2, guard shield 4 is threaded with obturating plug 1, also be provided with second seal ring 5 between guard shield 4 and the obturating plug 2, for the ease of the installation and removal of obturating plug 1 with guard shield 4, guard shield 4 is processed into hexahedron shape away from an end of obturating plug 1.
When oil plant can not re-use, when needing to change oil plant, take off guard shield 4, turn on countersunk screw 2, oil is emitted get final product.
The countersunk screw 2 outer guard shields 4 that are with; the inner countersunk screw 2 and first seal ring 3 are protected; not fragile; therefore do not need frequent replacing; be provided with second seal ring 5, double seal, good sealing effect in addition between guard shield 4 and the obturating plug 1; even one of them seal ring breaks down, do not influence sealing effect yet.
This dual-seal stopper can be made oil drain plug usefulness, also can make air relief cock and use.When on the radiator that is applied in transformer, this dual-seal stopper is mounted on the header pipe of radiator, doing venting for air relief cock on last header pipe uses, on lower header, be the oil drain plug usefulness of draining the oil, when oiling transformer, air relief cock on the radiator should be opened, when treating that vent hole has oily benefit, again air relief cock be tightened.
Claims (2)
1. dual-seal stopper, have obturating plug (1) and countersunk screw (2), countersunk screw (2) penetrates in the tapped hole of obturating plug (1), be provided with first seal ring (3) between obturating plug (1) and the countersunk screw (2), it is characterized in that: obturating plug (1) is provided with a guard shield (4) that covers countersunk screw (2), guard shield (4) is threaded with obturating plug (1), also is provided with second seal ring (5) between guard shield (4) and the obturating plug (2).
2. a kind of dual-seal stopper according to claim 1 is characterized in that: described guard shield (4) is shaped as hexahedron shape away from an end of obturating plug (1).
