Description
Technical field
The present invention relates to pipeline protection field, the protective cover of a kind of pipeline and installation method thereof.
Background technology
Pipeline in use, may face physical shock, corrosivity working environment or the high-temperature work environment of outside；The structure of pipeline may be had a negative impact thus affect and service life of pipeline even cause potential safety hazard by this.In order to overcome this defect, protective cover can be used to carry out protective conduit.
Prior art there is employing i.e. pipeline is formed protective cover in pipeline workshop, damage against the external world.But, in existing industry spot, the various pipelines needing protection have installed.And in some have been the situation installed, the production of pipeline is also over and is not easy to be again introduced into factory and carries out secondary operations.Accordingly, it would be desirable to a kind of pipeline is carried out protective cover that subsidiarity installs online or is dispatched from the factory after the protective cover installed, it can realize the protection needs for pipeline flexibly, to be adapted to the needs of various application scenario.
Summary of the invention
It is an object of the invention to provide protective cover and the installation method thereof of a kind of pipeline, it can overcome defect of the prior art.
nullThe protective cover of the pipeline according to the present invention，Heat insulation protective action is played for being set in the outside of pipeline，Including merging, composition is cylindrical lacks the main protection department of section cylinder and the cover body part lacking section cylinder as relatively roundlet as relatively great circle，Wherein，The bottom of described main protection department and the top of described cover body part are symmetrically arranged flexible to roof panel pipe fitting，It is provided with elastic clip assembly to the diametrically opposed lateral symmetry of described main protection department，Thus two described elasticity can form the clamping of the vertical direction for described pipeline to roof panel pipe fitting，Two diametrically opposed described elastic clip assemblies can form the clamping of the horizontal direction for described pipeline，Wherein，The left and right sides of the opening part of described main protection department is symmetrically arranged with the convex extension part extended towards one another，It is provided with circular arc head at the medial end of each described convex extension part，Beneficially to make described main protection department tentatively overlap be set to described pipeline from the bottom of described pipeline by described opening，And temporarily main protection department is carried on described pipeline and drops to prevent from getting loose；It is provided with two cylinders with top-slitting on the top surface of each described convex extension part and fixes groove in order to coordinate with two elastic deformation cylinder brackets at corresponding in the two of described cover body part end faces, wherein, the plane of symmetry position of each described elastic deformation cylinder bracket is provided with elastic deformation and allows gap；Wherein, each described elasticity includes that to roof panel pipe fitting the pipeline being oppositely arranged engages arm and auxiliary support arm, described pipeline engages the plateau elastic bending section that arm includes being connected with the body of main protection department, the platform part being connected with described plateau elastic bending section is in order to engage described pipeline, and the support engagement angled portion being connected with described platform part, described auxiliary support arm includes the sub-arm elastic bend part being connected with the body of described main protection department and is connected with described sub-arm elastic bend part and in order to the inclined shore portion being slidably matched with described support engagement angled portion, thus, when roof panel pipe fitting is pressed active force that elastic deformation occurs by the top of described pipeline by the most described elasticity, described support engagement angled portion can occur relatively to slide relative to described inclined shore portion；nullWherein，Described main protection department is provided with multiple described elastic clip assembly along the longitudinal direction on the every side in described diametrically opposed both sides，Each described elastic clip assembly all includes about symmetrically arranged two elastic clips of diametric(al)，In said two elastic clip one is V-type elastic bending piece，One support arm of described V-type elastic bending piece is connected with the main body of described main protection department，Another support arm is with another the corresponding support arm arranged crosswise in said two elastic clip thus realizes supporting for the staggered form of described pipeline engaging，Between described main protection department and described cover body part, junction is provided with elastic sealing gasket，Described elastic sealing gasket is fixing with described main protection department to be connected，Described elastic sealing gasket is that elastomeric material is made，Described elastic sealing gasket causes the corrosion to described pipeline in order to prevent the liquid such as aqueous vapor from entering from the gap between described main protection department and described cover body part.
According to the present invention, the installation method of above-mentioned protective cover, first, described opening up by described main protection department, make described convex extension part fix the space generation elastic deformation of groove by described cylinder from the bottom of described pipeline by described opening thus described main protection department is installed and be carried on described pipeline, then, fix in groove described cover body part is fixed on described main protection department by described elastic deformation cylinder bracket being inserted and being coupled to described cylinder, thus utilize two described elasticity of described main protection department that roof panel pipe fitting is formed the clamping of the vertical direction for described pipeline, diametrically opposed described elastic clip assembly is utilized to form the clamping of the horizontal direction for described pipeline.
By the present invention, owing to being provided with the main protection department with upper opening, therefore, it is possible to make protective cover carry out at the scene installing and being carried on pipeline.And when assembling, owing to guard shield is divided into two parts not of uniform size, therefore, the opening of the main protection department of major part lacks opening for circle, it is easy to temporarily be carried on by protective cover on pipeline and is difficult to drop；It is positioned at the convex extension part of this opening part by setting and utilizes circular groove, it is possible to occurring elastic deformation temporarily to be blocked by guard shield in installation process, this is for especially advantageous during the guard shield that is installed axially along the pipe and gradually.After assembling, cover body part is upward, enable to described convex extension part as guard shield by the gravity standby supporting part of pressure-bearing downwards, avoid the guard shield excessive convergence that the self gravitation of guard shield causes during installing and using for a long time for the long-term biased deformation in the elastomeric platform pipe portion of guard shield, so that peripheral circular air space occurs extruding to affect effect of heat insulation.Whole guard apparatus has easy for installation, firmly installs and service-strong advantage.Can effectively solve the problem that the problems of the prior art.
