Description
Technical field
This utility model belongs to industrial fluids pipe transportation technology field, specifically a kind of protective cover carrying pipe adpting flange or expansion joint。
Background technology
In industry transportation art, it is common to use conveying pipe realizes the conveying of the various fluids such as liquid, solid-liquid mixture and gas。Just need to adopt Flange joint when pipe fluid pressure is bigger more than 4Mpa or pipe diameter, carry out the long-distance sand transport of high temperature, high-pressure fluid。It addition, in order to prevent fluid delivery pump operationally owing to vibration makes itself and pipeline junction produce to loosen, also tending to can at the expansion joint importing and exporting installation rubber or metal material of pump to alleviate the impact that above-mentioned vibration produces。
But, flange or expansion joint are typically exposed in air in use, it is susceptible to corrosion and aging and damage, and owing to the impact of the factor of expanding with heat and contract with cold makes expansion joint produce loosening with the junction of pipeline, cause the leakage of conveying tube fluid, it is likely to produce splash phenomena, contaminated environment, destruction industrial plants under elevated pressure conditions, even causes personal security accident。
Utility model content
The purpose of this utility model is to solve above-mentioned technical problem, it is provided that a kind of simple in construction, convenient disassembly, can effectively prevent the conveying pipe adpting flange of the leakage of fluid in pipeline or the protective cover of expansion joint。
For reaching above-mentioned purpose; this utility model is by the following technical solutions: a kind of protective cover carrying pipe adpting flange or expansion joint; including cover body, this cover body is by being buckled into cylindrical first cover body and the second cover body is constituted, and cylinder is internally formed the cavity for holding ring flange or expansion joint；The tabular connecting portion for arranging clamp device is extended in first cover body and the second cover body outer rim both sides, and this connecting portion is provided with perforate。
The cylinder that above-mentioned first cover body and the second cover body are formed after fastening can increase the accommodation space of flange or expansion joint, and can reduce dirt piling up thus reducing the load of conveyance conduit on protective cover。
In order to strengthen the protective effect to flange or expansion joint further, 2 ~ 3cm arc protective tube that can be fitted on conveying pipe is extended in the first cover body and the second alignment both sides, cover body Jun Yan center。
The connecting portion for arranging clamp device is extended in arc protective tube outer rim both sides, and this connecting portion is provided with perforate。
First cover body, the second cover body and arc protective tube inwall are equipped with the anticorrosive coat of 1mm, it is prevented that leakage corrosion protection cover occurs for conveying pipe adpting flange or expansion joint place。
First cover body, the second cover body and arc protective tube are played fastening effect through perforate by bolt or buckle。
This utility model is compared to prior art, have the advantages that this utility model is mainly by being buckled into cylindrical first cover body and the second cover body, and the accommodation cavity of ring flange or expansion joint is constituted, it is possible to prevent leakage and the injection of conveying tube fluid, improve processing safety；The arc protective tube that first cover body and the second cover body extend along alignment both sides, center can strengthen the protective effect to flange or expansion joint further；The connecting portion being provided with perforate is extended in first cover body and the second cover body outer rim both sides, adopts bolt or buckle, through perforate, the first cover body, the second cover body are played fastening effect, it is possible to prevents coming off or loosening of protective cover, improves the stability of work process；First cover body, the second cover body and arc protective tube inwall are equipped with the anticorrosive coat of 1mm, it is possible to prevent conveying pipe adpting flange or expansion joint place from leakage corrosion protection cover occurring, improve the service life of protective cover。

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail。
As it is shown in figure 1, a kind of protective cover carrying pipe adpting flange or expansion joint, including cover body 1, this cover body 1 is constituted by being buckled into cylindrical first cover body 1-1 and the second cover body 1-2, and cylinder is internally formed the cavity for holding ring flange or expansion joint；First cover body 1-1 and the second cover body 1-2 outer rim both sides are all extended and are extended 2 ~ 3cm arc protective tube 4 that can be fitted on conveying pipe for the alignment both sides, connecting portion 3, Bing Junyan center being provided with perforate arranging clamp device；First cover body 1-1, the second cover body 1-2 and arc protective tube 4 inwall are equipped with the anticorrosive coat 5 of 1mm。
This utility model is in the specific implementation; first anticorrosive coat 5 is made to be fitted in the inwall of the first cover body 1-1, the second cover body 1-2 and arc protective tube 4; then the first cover body 1-1 and the second cover body 1-2 that are connected to arc protective tube 4 are fastened on conveying pipe adpting flange or expansion joint; finally through the perforate 3 on connecting portion 2, first cover body 1-1 and the second cover body 1-2 is fastened on flange or expansion joint with bolt or buckle; arc protective tube 4 is fastened on conveyance conduit, thus realizing the protection to flange or expansion joint。
