Movable detachable sealing device

Abstract

The invention discloses a movable detachable sealing device. The movable detachable sealing device comprises a connecting assembly. The connecting assembly is additionally arranged, an upper abutting sealing ring is connected to the inner thread ring face on the inner side of the periphery of an upper floating ring in a rotating and threaded mode from top to bottom through an outer thread mounting ring body, and the sealing ring is driven to abut against the periphery of the upper side of the abutting ring body downwards; and a lower abutting sealing ring is in threaded connection with the inner thread ring surface on the inner side of the periphery of a lower positioning ring through rotation of the outer thread mounting ring body from bottom to top, and drives the sealing ring to upwards abut against the periphery of the lower side of the abutting ring body, so that a movable mounting structure of the upper abutting sealing ring and the lower abutting sealing ring is achieved, and dismounting and mounting are very convenient.

Description

technical field [0001] The invention relates to a movable detachable sealing device. Background technique [0002] At present, the sealing ring is a common item used to prevent the leakage of oil, gas, water, dust, etc., and most of the sealing rings are made of soft materials such as metal outer rings and rubber inner rings, which are mainly provided by the elasticity of the material itself. The sealing force is used to achieve the sealing effect. Most of the existing sealing rings have a standard circular or elliptical cross-section, and their inner peripheral surfaces are extruded to form an inner sealing surface. Sealing rings with this structure are widely used in various industries because of their convenient manufacture and low cost.

Problems solved by technology

[0002] At present, sealing rings are common items used to prevent leakage of oil, gas, water, dust, etc. Most of the sealing rings are made of soft materials such as metal outer rings and rubber inner rings, which are mainly provided by the elasticity of the materials themselves. The sealing force is used to achieve the sealing effect. Most of the existing sealing rings have a standard circular or elliptical cross-section, and their inner peripheral surfaces are extruded to form an inner sealing surface. Sealing rings with this structure are widely used in various industries because of their convenient manufacture and low cost. In various industries; however, the existing sealing rings mainly provide sealing force by the elasticity of the material itself to achieve the sealing effect, but the fastening force of its own elasticity often cannot achieve good sealing performance, and in addition, due to the soft texture of rubber and other materials , so after a long time of stress, it is very easy to lose the sealing effect due to deformation, which greatly weakens the actual sealing effect of the sealing ring. In addition, different sealing diameters sometimes need to be fine-tuned, and the existing sealing device does not have the ability to adjust the sealing Diameter structure, in addition, it is necessary to improve the convenience of disassembly and installation of the sealing device
