Abstract
The utility model discloses a sealing ring. The sealing ring comprises a sealing ring body. The sealing ring body comprises a round metal ring. A gap is formed in the round metal ring. The two ends of the gap are connected with each other through an insulating block. Wires are arranged on the two sides of the gap. The wires are connected with the positive electrode and the negative electrode of a power source. Due to the fact that the side pressure of an existing sealing ring is not enough after the existing sealing ring is installed, the round metal ring is powered on and heated according to the structure, and the round metal ring slightly expands according to the principle of expansion caused by heat and contraction caused by cold so that the pressure on the side face can be increased. In this way, the sealing effect of the sealing ring is improved and the possibility of leakage is reduced.
Description
Technical field
The utility model relates to seal fitting technical field, relates in particular to a kind of seal ring.
Background technique
The joint of existing liquid conducting pipes generally all connects by flange, and in order to prevent that seepage is all provided with seal ring in flange inside, but existing seal ring may because of the impacting force deficiency of flange both sides, sealability be bad, may cause certain seepage.
Also likely in the time of pipe laying, possibility weather is warmmer, volume when seal ring is installed is larger, after flange being tightened with bolt sealing effect was good at that time, but to winter because expand with heat and contract with cold and may occur certain gap between flange and seal ring, so just may cause pipe leakage.
Summary of the invention
The utility model is not enough for prior art, and a kind of seal ring is provided, and this kind of seal ring can increase the impacting force between seal ring and flange after installing, and improves sealability, and reduces the leakage problems that weather reason is expanded with heat and contract with cold and brought.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of seal ring, comprise seal ring body, described seal ring body comprises a metal cirque, on described metal cirque, be provided with breach, described breach two ends connect by collets, and described breach both sides are provided with wire, and described wire connects respectively the both positive and negative polarity of power supply.Because the side pressure after the installation of script seal ring may be not, adopt this structure that metal cirque is switched on and heated, according to the principle of expanding with heat and contract with cold, eyelet is expanded a little and strengthen the pressure to side, the sealing effect of seal ring is improved, reduce the possibility of seepage.
In technique scheme, preferred, also include impeller, described impeller is arranged on pipe interior, described pipeline external is provided with power generating equipment, and described impeller drives described power generating equipment to generate electricity by magnetic transmission, and the both positive and negative polarity of described power generating equipment connects respectively described wire.Adopt the way to take power of this structure, when pipe interior has liquid to flow through, impeller just rotates and drives power generating equipment generating, in the time of can guaranteeing that sealing circle makes the pipeline of use have liquid to flow through in inside, metal cirque just heats, when having liquid to flow through, just do not heat, in order to avoid heating causes damage to seal ring body for a long time.
In technique scheme, preferred, on described seal ring body, be coated with insulation coating, like this can be so that sealing circle can be used in the connection of metallic conduit, in order to avoid electric leakage.
In technique scheme, preferred, described metal cirque has thermo electric material.After adding thermo electric material for increasing the energising of sealing circle, the amount of heating, improves using effect.
The utility model compared with prior art, there is following beneficial effect: the side pressure after the utility model is installed according to script seal ring may be not, adopt this structure that metal cirque is switched on and heated, according to the principle of expanding with heat and contract with cold, eyelet is expanded a little and strengthen the pressure to side, the sealing effect of seal ring is improved, reduce the possibility of seepage.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's schematic diagram.
Fig. 2 is the sectional view of the utility model embodiment seal ring.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: referring to Fig. 1 to Fig. 2, a kind of seal ring, comprise seal ring body 1, described seal ring body 1 comprises a metal cirque 11, on described metal cirque 11, be provided with breach 111, described breach 111 two ends connect by collets 12, and described breach 111 both sides are provided with wire 2, and described wire 2 connects respectively the both positive and negative polarity of power supply.Just for metal cirque 11 heats when pipe interior has liquid to flow through, also include impeller 3, described impeller 3 is arranged on pipe interior, described pipeline external is provided with power generating equipment 4, described impeller 3 drives described power generating equipment 4 generatings by magnetic transmission, and the both positive and negative polarity of described power generating equipment 4 connects respectively described wire 2.In order to make sealing circle can be applied to the connection of metallic conduit, leakproof is coated with insulation coating 13 on described seal ring body 1, and in order to make heating effect better, described metal cirque 11 has thermo electric material.
This seal ring when mounted, is fixed on inner-walls of duct by impeller 3, and then by power generating equipment 4 correspondences be arranged on pipeline outside, wire 2 is connected with the both positive and negative polarity of power generating equipment 4.
In pipeline, have liquid to rotate through out-of-date impeller 3, impeller 3 drives 4 generatings of outside power generating equipment to eyelet 11 energisings by magnetic transmission, after eyelet 11 heating powers, expands and increases the pressure of oppose side wall, has so just improved sealability.
