Problems solved by technology

[0002] During the sealing process of oil pipeline joints, most of them are sealed with combined sealing gaskets. The existing combined sealing gaskets are flat gaskets with metal stamping parts as the outer ring and rubber as the inner ring. Although the sealing performance is better than that of conventional metal Gaskets and non-metallic gaskets have been improved, but the combined sealing gasket is formed by bonding and vulcanizing the rubber ring and the metal ring as a whole, which needs to be replaced as a whole, which increases the cost of use

Abstract

The invention discloses a combined type sealing frame ring. The combined type sealing frame ring comprises a frame ring body, a sealing washer, a first groove, a second groove and a connecting channel, the first groove and the second groove are formed in the upper end and the lower end of the frame ring body correspondingly, the connecting channel used for communicating the first groove with the second groove is formed in the frame ring body, the sealing washer is arranged in the connecting channel, a first annular protrusion and a second annular protrusion which are matched with the first groove and the second groove are integrally formed at the upper end and the lower end of the sealing washer correspondingly, the upper end of the first annular protrusion exceeds the first groove, the lower end of the second annular protrusion exceeds the lower end of the second groove, and the frame ring body is a big-end-down T-shaped body. Compared with the prior art, the use cost can be reduced, and the structure is simple.

Description

【Technical field】 [0001] The invention relates to the technical field of hinged joints, in particular to the technical field of a combined sealing frame. 【Background technique】 [0002] During the sealing process of oil pipeline joints, most of them are sealed with combined sealing gaskets. The existing combined sealing gaskets use metal stamping parts as the outer ring and rubber as the inner ring. Although the sealing performance is better than that of conventional metal Gaskets and non-metallic gaskets have been improved, but the combined sealing gasket is formed by bonding and vulcanizing the rubber ring and the metal ring as a whole, which needs to be replaced as a whole, which increases the cost of use. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a combined sealing frame ring, which can reduce the use cost and has a simple structure. [0004] In order to achieve the above object, the pre...
