Abstract
The invention discloses a safety protective sleeve of a flange, belonging to the technical field of chemical industry safety production. The safety protective sleeve of a flange is composed of a sleeve body, an upper sector, an upper right magic viscous mass, an upper folding sheet, an upper left magic viscous mass, a folding sheet, a left magic viscous mass, a right magic viscous mass and a lower sector. The invention is characterized in that the upper part of the sleeve body is connected with the upper sector, the lower part of the sleeve body is connected with the lower sector, the middle part of the upper sector is hollow, and the middle part of the lower sector is hollow; the sleeve part is provided with the folding sheet which is provided with the right magic viscous mass; the sleeve body corresponding to the folding sheet is provided with the left magic viscous mass; the upper folding sheet on the upper sector is provided with the upper right magic viscous mass; and the position of the upper folding sheet, which corresponds to the upper sector, is provided with the upper left magic viscous mass. The invention is prepared by chemical fiber cloth. During installation, the folding sheet position on the safety protective sleeve of the flange of the invention is sheathed from the flange position; then the upper folding sheet on the upper sector is turned to cause the upper right magic viscous mass and the upper left magic viscous mass to be adhered, and operating personnel can avoid the injection of chemical industry material. The invention has the beneficial effects of simple design, convenient use, safety, environment protection and big practicality.
Description
Affiliated technical field
The present invention relates to a kind of flange safety protective cover, relate in particular to the flange safety protective cover that a kind of evil spirit is connected, belong to chemical industry safety production technique field.
Background technique
At present; in the Chemical Manufacture of known technology; liquid in the chemical pipeline can leak from the flange connections of static sealing point; after poisonous harmful substance material leaks from flange connections, can cause the spray line of buttress shaft, cause when checking to be sprayed directly on on the health to the operator; cause environmental pollution and security incident; before this practicality is not made, there is not the flange safety protective cover use that evil spirit is connected, it is open that the patent searching document does not have technological scheme.
Summary of the invention
In order to overcome the deficiency of not having the magic flange safety protective cover that is connected in the prior art; flange safety protective cover in order to provide a kind of evil spirit to be connected is provided; this flange safety protective cover can wrap up the chemical pipeline flange connections of naked installation, can reach the injection of the liquid of stopping a leak.
The present invention solves the technological scheme that its technical problem takes: by body; last covering of the fan; go up right magic grume; last tabs; go up left magic grume; tabs; the magic grume in a left side; right magic grume; following covering of the fan is formed; it is characterized in that body top connects upward covering of the fan; the body bottom connects covering of the fan down; last covering of the fan middle part is hollow; following covering of the fan middle part is hollow; the cover body leaves tabs; tabs is provided with right magic grume; leave left magic grume on the body of tabs correspondence; right magic grume is left in the tabs joint on the last covering of the fan; left magic grume is left at the position of covering of the fan on the last tabs correspondence; the present invention adopts chemical fiber cloth to make; be inserted in from flange at the tabs position that during installation flange safety protection of the present invention is put; then the last tabs on the last covering of the fan being stirred makes right magic grume mutually bonding with the magic grume in a last left side; tabs on the body stirs and makes right magic grume mutually bonding with left magic grume; wait to be inserted in flange position arrangement smooth after; each magic grume application of force made it to compress get final product; when the liquid material in the chemical pipeline leaks outflow; all can flow in the chase in the body; the operator can avoid the injection of chemical material, and the material in chase can be recycled.
The invention has the beneficial effects as follows simplicity of design, easy to use, safety and environmental protection, practicability is bigger.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a schematic representation of the present invention.
1. bodies among Fig. 1 are 2. gone up covering of the fan, 3. go up right magic grume, 4. go up tabs, 5. go up left magic grume, 6. tabs, and 7. left magic grume, 8. right magic grume 9. descends covering of the fan.
Embodiment
The present invention is by body 1; last covering of the fan 2; go up right magic grume 3; last tabs 4; go up left magic grume 5; tabs 6; the magic grume 7 in a left side; right magic grume 8; following covering of the fan 9 is formed; it is characterized in that body 1 top connects upward covering of the fan 2; body 1 bottom connects covering of the fan 9 down; last covering of the fan 2 middle parts are hollow; following covering of the fan 9 middle parts are hollow; 1 one of body leaves tabs 6; tabs 6 is provided with right magic grume 8; leave left magic grume 7 on the body 1 of tabs 6 correspondences; right magic grume 3 is left in tabs 4 joints on the last covering of the fan 2; left magic grume 5 is left at last tabs 4 corresponding positions of going up covering of the fan 2; the present invention adopts chemical fiber cloth to make; be inserted in from flange at tabs 6 positions that during installation flange safety protection of the present invention put; then the last tabs 4 on the last covering of the fan 2 being stirred makes the magic grume in a right magic grume 3 and a last left side 5 mutually bonding; tabs 6 on the body 1 stirs and makes right magic grume 8 mutually bonding with left magic grume 7; wait to be inserted in flange position arrangement smooth after; each magic grume application of force made it to compress get final product; when the liquid material in the chemical pipeline leaks outflow; all can flow in the chase in the body 1; the operator can avoid the injection of chemical material, and the material in chase can be recycled.
