Therefore, the safety management strengthening equipment in Chemical Manufacture is particularly important, particularly in chemical pipeline maintenance process, because pipeline stands the invasion and attack of chemical raw material throughout the year, be easy to cause corrosion, of common occurrence to the maintenance of chemical pipeline, but, due to pipeline is carried out in cutting Renewal process, when pressure in pipe is not measured, carrying out rashly is sawed-off, be easy to cause the chemical substance in pipe to splash, maintenance personal is made to be subject to the erosion of chemical substance then and there, cause life accident, therefore, the utility model is by arranging a pair protective cover, by during to manual sawed-off pipeline, prevent from managing the splash under pressure differential of interior article, the personal safety of protection maintenance personal.
Utility model content
The technical problems to be solved in the utility model is by arranging a pair transparent shield body structure; this structure has easy for installation; make simple; when being conveniently used for the maintenance of chemical pipeline; to the protective effect of staff, when avoiding carrying out trouble hunting to chemical pipeline, the chemical substance splash in pipe is out caused chemistry injury to maintenance personal by pipe pressure; when solving the maintenance of existing chemical pipeline, cause the problems such as personnel's accident without any safety prevention measure.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model is provided for the protective cover of chemical pipeline maintenance cutting, and comprise curved cover body, the both sides of described cover body are respectively equipped with circular hole, and described circular hole coordinates with expansion link; Described expansion link one end is provided with angle-style block, and the described expansion link other end is provided with screw thread guide pillar, and on described expansion link, cover has spring, and described screw thread guide pillar and draw ring are fixed, and described draw ring is an annulus, and side is provided with holder.
Further, described cover body is safety glass material, and radian is greater than 180 °, and described cover body is arranged in pairs on pipeline, and the spacing between described two adjacent cover body end faces is in the scope of 1cm-5cm.
Further, described expansion link and circular hole are slidably matched, and the length of described expansion link is less than the length of spring, make expansion link be subject to the preload force of spring all the time, utilize spring to clamp pipeline, easy for installation, use flexibly.
Further, described angle-style block is right angle, directly contacts, for fixed enclosure with pipeline side.
Further, described draw ring is plastic material, and the holder that side is arranged is provided with the internal thread coordinated with screw thread guide pillar; By pulling draw ring, make angle-style block near cover body madial wall, then clamping pipe under the action of the spring.
The utility model is provided for the protective cover of chemical pipeline maintenance cutting, and its beneficial effect is:
The utility model is by arranging a pair transparent shield body structure; this structure has easy for installation; make simple, when being conveniently used for the maintenance of chemical pipeline, to the protective effect of staff; when avoiding carrying out trouble hunting to chemical pipeline; chemical substance splash in pipe is out caused chemistry injury to maintenance personal by pipe pressure, when particularly manually cutting pipeline, because interior pressure is larger in pipe; be easy to cause chemical substance to splash out, the danger caused casualties.
