Further, the center position of the top of the rubber inner ring is provided with a wedge-shaped ring part.

Further, the metal outer ring is made of stainless steel material.

Further, the upper surface of the oil-absorbing felt ring is lower than the upper surface of the rubber inner ring.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the utility model discloses multilayer combination packing ring uses the mode of vulcanizing to combine as an organic wholely with metal outer loop inner wall through setting up rubber inner circle lower half to can effectively improve the fastness that rubber inner circle lower half and metal outer loop inner wall combined.

2. The utility model discloses multilayer combination packing ring is connected with oil absorption felt circle through circle first periphery use vulcanization mode in rubber to can effectively strengthen the fastness of circle first and oil absorption felt circle combination department in the rubber, and oil absorption felt circle set up the leak protection effect that can the effective value reinforcing packing ring body, and then avoid fluid to spill from oil pipeline connector, cause oil pipeline to take place too big loss at oil transportation in-process fluid.

3. The multilayer combined gasket of the utility model can effectively enhance the wear resistance of the outer surface of the metal outer ring by electroplating the wear-resistant metal chromium layer on the outer surface of the metal outer ring, and avoid the loss of the sealing performance of the gasket body caused by the abrasion of the metal outer ring by external force in the fastening process; the metal outer ring is made of the stainless steel material, so that the hardness of the metal outer ring made of the stainless steel material is high, the corrosion resistance is good, the gasket body is prevented from being corroded too fast by oil containing acidic substances, and the service life of the gasket body is prolonged.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-4, a novel multilayer combined gasket comprises a gasket body 1, wherein the gasket body 1 is composed of a metal outer ring 2 and a rubber inner ring 3, the lower half part of the rubber inner ring 3 is combined with the inner wall of the metal outer ring 2 into a whole in a vulcanization mode, the periphery of the upper half part of the rubber inner ring 3 is combined with an oil absorption felt ring 4 into a whole in a vulcanization mode, the bottom of the oil absorption felt ring 4 is connected to the top of the metal outer ring 2 in a gluing mode, and a wear-resistant metal chromium layer 6 is electroplated on the outer surface of the metal outer ring.

Wherein, the center position of the top of the rubber inner ring 3 is provided with a wedge-shaped ring part 5.

In this embodiment, as shown in fig. 2 and 3, the wedge-shaped ring portion 5 is disposed at the top center of the rubber inner ring 3, so as to play a role of diversion buffering, so as to guide oil at the connection surface of the pipe joint into the center of the gasket body 1, thereby preventing the oil from directly impacting the rubber inner ring 3 on one side to damage the rubber inner ring 3.

Wherein the metal outer ring 2 is made of stainless steel material.

In the embodiment, as shown in fig. 1 and 2, the metal outer ring 2 made of the stainless steel material has high hardness and good corrosion resistance, so that the gasket body 1 is prevented from being corroded too fast by oil containing acidic substances, and the service life of the gasket body 1 is further prolonged.

Wherein, the upper surface of the oil absorption felt ring 4 is lower than the upper surface of the rubber inner ring 3.

In this embodiment, as shown in fig. 1, the upper surface of the oil absorption felt ring 4 is lower than the upper surface of the rubber inner ring 3, so that the rubber inner ring 3 can be ensured to contact the pipe joint connection surface as much as possible when sealing, and further, when the sealing of the pipe joint connection surface is improved, the oil absorption felt ring 4 is prevented from directly contacting the pipe joint connection surface and being worn away too fast, so that the oil absorption felt ring loses the leakage-proof effect.

It should be noted that, the utility model relates to a novel multilayer combined washer, during operation, personnel install the washer body 1 at the pipe joint connecting surface of two oil pipelines, and use fastening bolt to accomplish the fastening butt joint of the pipe joint connecting surface of two oil pipelines, because the lower half of rubber inner ring 3 uses the mode of vulcanization to combine with the inner wall of metal outer ring 2 as an organic whole, thereby can effectively improve the fastness of the combination of the lower half of rubber inner ring 3 and the inner wall of metal outer ring 2, avoid the lower half of rubber inner ring 3 and metal outer ring 2 from being too big and not firm when using fastening bolt to fasten, because of receiving too big external force to fix, and take place to separate; in the oil transportation process of the oil transportation pipeline, the periphery of the upper half part of the rubber inner ring 3 is connected with the oil absorption felt ring 4 in a vulcanization mode, so that the firmness of the joint of the upper half part of the rubber inner ring 3 and the oil absorption felt ring 4 can be effectively enhanced, the oil absorption felt ring 4 can effectively enhance the leakage-proof effect of the gasket body 1, and further, the oil is prevented from leaking out of a connector of the oil transportation pipeline, and the oil loss of the oil transportation pipeline in the oil transportation process is avoided; 3 top central point of rubber inner circle puts the setting of wedge ring portion 5 to can play the effect of water conservancy diversion buffering, put into the leading-in packing ring body 1 central point of fluid with the pipe joint connection face department, and then avoid fluid direct impact rubber inner circle 3 of one side, lead to rubber inner circle 3 to damage.
