Abstract

The utility model discloses a flange protecting device. The flange protecting device comprises an upper semi-circular cylinder body and a lower semi-circular cylinder body, wherein the upper semi-circular cylinder body and the lower semi-circular cylinder body are arranged on a flange, and an integrated cylinder body is formed by the upper semi-circular cylinder body and the lower semi-circular cylinder body in a butt joint way; one end surface of the cylinder body is provided with an upper semi-circular annular end part sealing plate and a lower semi-circular annular end part sealing plate, and an integrated annular end part sealing plate is formed by the upper semi-circular annular end part sealing plate and the lower semi-circular annular end part sealing plate in the butt joint way; the other end surface of the cylinder body is provided with an upper semi-circular annular end part panel and a lower semi-circular annular end part panel, and an integrated annular end part panel is formed by the upper semi-circular annular end part panel and the lower semi-circular annular end part panel in the butt joint way; the end surfaces of the upper semi-circular annular end part panel and the lower semi-circular annular end part panel are respectively provided with a bolt clamping groove matched with the flange, and the bottom part of the lower semi-circular cylinder body is provided with an observation hole. According to the flange protecting device disclosed by the utility model, two end surfaces of the cylinder body are respectively provided with the annular end part panel and the annular end part sealing plate, thus the flange can be ensured not to be easily damaged by a machine as the flange can be covered by the cylinder body as well as the panel and the sealing plate at the two ends of the cylinder body, meanwhile, the flange is ensured not to be corroded, and the service life is prolonged.

Description

A kind of flange protection device
Technical field
The utility model relates generally to the flange protection device of boats and ships upper pipeline system.
Background technique
At present, conventional cloth formula flange protecting cover or flange protection cover are directly placed on flange outer surface using the protective gear as flange, and this kind of protective gear is because surface is without any hole, therefore, can effectively prevent leak of liquid and the high-temperature steam splash of the flange connections generation of pipe-line system, but, because cloth formula flange protection cover and flange protection cover surface is without any hole, therefore, cannot observe system pipeline and whether have seepage, easily incur loss through delay engineering time, bring potential safety hazard to the staff on boats and ships; In addition; because cloth formula flange protection cover or flange protection cover all cannot be fixed on flange or pipeline; therefore; when vessel motion; can make pipe-line system produce vibration, thus its relative cloth formula flange protection cover or the motion of flange protection cover, so that produce friction between cloth formula flange protection cover or flange protection cover and pipeline; be easy to destroy the paint on pipeline surface, accelerate the corrosion of pipeline.
Model utility content
The utility model aims to provide and is a kind ofly fixed on flange and whether observable pipeline has the flange protection device of leakage.
A kind of flange protection device described in the utility model, comprise the upper semi-circle cylindrical shell and the lower semi-circle cylindrical shell that are arranged on flange, on, the docking of lower semi-circle cylindrical shell forms complete cylindrical shell, on cylindrical shell one end face, be provided with first annulus end shrouding and second annulus end shrouding, on, second annulus end shrouding docking forms complete annular end shrouding, on cylindrical shell other end, be provided with first annulus end panel and second annulus end panel, on, second annulus end panel docking forms complete annular end panel, on, on the end face of second annulus end panel, be respectively arranged with the bolt draw-in groove matching with flange, be provided with peep hole in lower semi-circle ring cylinder bottom.
A kind of flange protection device described in the utility model, by relative being arranged on flange of upper and lower semicircle cylindrical shell with semicircular ring end shrouding and semicircular ring end panel, and by the screw thread draw-in groove on the end face of the fastening piece screw-in end panel such as bolt, upper and lower semicircle cylindrical shell is fixed on flange; Owing to being respectively arranged with annular end panel and annular end shrouding in cylindrical shell both ends of the surface, can guarantee that flange is covered by the panel at cylindrical shell and two ends thereof and shrouding, be not subject to mechanical damage, the bolt that simultaneously also guarantees pad between flange, two flanges and fastening flange is avoided corrosion, extends flange working life; And in lower semi-circle ring cylinder bottom, peep hole is set, and in the situation that not needing to dismantle flange protective gear, can judge in time whether flange has seepage, and safeguard in time, can further prevent from when liquid in pipeline from surprisingly spraying, personnel and peripheral equipment being caused damage.In addition, during due to flange protection device, be directly fixed on flange, therefore, when pipe-line system vibration, flange protection device is flange and pipeline motion relatively not, and pipeline and flange therefore can not wear and tear.This kind of flange protection apparatus structure is simple, and processing cost is low.

Fig. 2 is the utility model left view.
Fig. 3 is the partial enlarged drawing of Fig. 1 A.
Embodiment
A kind of flange protection device, as shown in Figure 1 to Figure 3, comprise the upper semi-circle cylindrical shell 1 and the lower semi-circle cylindrical shell 2 that are arranged on flange, on, the docking of lower semi-circle cylindrical shell forms complete cylindrical shell, on cylindrical shell one end face, be provided with first annulus end shrouding 3 and second annulus end shrouding 4, on, second annulus end shrouding docking forms complete annular end shrouding, on cylindrical shell other end, be provided with first annulus end panel 5 and second annulus end panel 6, on, second annulus end panel docking forms complete annular end panel, on, on the end face of second annulus end panel, be respectively arranged with the bolt draw-in groove 7 matching with flange, be provided with peep hole in lower semi-circle ring cylinder 2 bottoms.
The interior ring radius of the annular end panel that the interior ring radius of the annular end shrouding that the shrouding docking of described upper and lower semicircular ring end forms and the docking of upper and lower semicircular ring end panel form is greater than the radius of flange endoporus, guarantees that damage pipeline is scraped at the interior ring edge of annular end panel and annular end shrouding.
The end face joint of upper and lower semicircle cylindrical shell is respectively arranged with the baffle plate 8 that simultaneously connects upper and lower semicircle cylindrical shell, so that upper and lower semicircle cylindrical shell becomes an entirety, prevents its slippage from flange in system pipeline vibration processes.
The edge rounding of described cylindrical shell, annular end shrouding and annular end panel, prevents that it from damaging installation personnel because of sharp edges, also makes flange protection device more attractive in appearance simultaneously.
