Pressure vessel pipeline sealing vibration isolation device and working principle thereof

Abstract

The invention provides a pressure vessel pipeline sealing vibration isolation device and a working principle thereof. The device comprises a feeding pipeline, a feeding pipe head, a pressure vessel body, a discharging pipe head, a discharging pipeline and a first connecting seat, wherein the right end of the feeding pipeline is in threaded connection with an inlet in the left side of the pressure vessel body through the feeding pipe head; and an outlet in the right side of the pressure vessel body is in threaded connection with the left end of the discharging pipeline through the discharging pipe head. According to the pressure vessel pipeline sealing vibration isolation device and the working principle thereof, a fastening nut, a fixed screw, a movable hole, a movable seat, a sealing ring body and a sealing collar are arranged, so that the connection tightness between the feeding pipeline and the feeding pipe head is guaranteed, and leakage is avoided; the fastening nut is rotated to act on the outer wall of the fixed screw, so that the movable seat can move inwards on the outer wall of the fixed screw through the movable hole; meanwhile, the movable seat drives the sealing ring body and the sealing collar to abut against the feeding pipe head, so that the sealing effect is guaranteed, and then the pipeline connection tightness is guaranteed; and meanwhile, threaded connection can be disassembled, so that maintenance is facilitated.

Description

technical field [0001] The invention belongs to the technical field of sealing and vibration isolation, and in particular relates to a pressure vessel pipeline sealing vibration isolation device and its working principle. Background technique [0002] A pressure vessel refers to a closed device that contains gas or liquid and carries a certain pressure. The pressure vessel has a wide range of uses. [0003] At present, the pressure pipeline refers to all pipelines that are subjected to internal or external pressure, regardless of the medium in the pipeline, while the pressure vessel pipeline is the pipeline connecting the pressure vessels, and the connection between the pressure vessel body and the pipeline is usually equipped with seals, vibration isolation, etc. The device, on the one hand, needs to seal the high-pressure gas in the pressure vessel, and on the other hand, needs to perform vibration isolation treatment between the relatively vibrating pipeline and the press...
