Abstract
The invention relates to a manhole device of a tank truck, which comprises a manhole seat and a manhole cover and is characterized in that: the manhole cover is provided with a vent valve. The device has the advantages that: time and labor are saved during starting and a vent and pressure relief valve is provided, so that the protection effect on personal safety is achieved.
Description
Technical field
The present invention relates to a kind of tank car manhole device, belong to the manhole field.
Background technology
Manhole during existing tank car uses does not have pressure-relief valve, owing in the jar certain pressure is arranged, the phenomenon that manhole cover lifts suddenly can occur when opening manhole cover, causes personal injury easily.
Summary of the invention
The purpose of this invention is to provide a kind of tank car manhole device that can play a protective role to personal safety.
The objective of the invention is to realize in the following manner:
The present invention includes manhole collar, manhole cover, it is characterized in that: aie escape valve is installed on manhole cover.
Two power assistant spring are installed on the adapter shaft of above-mentioned manhole collar and manhole cover symmetrically.
Above-mentioned aie escape valve is a ball valve.
Be provided with a slice gauze in the bottom of above-mentioned manhole cover, gauze has a steel plate with holes.
Between manhole collar and manhole cover, be provided with seal ring above-mentioned.
Advantage of the present invention is: it is time saving and energy saving to open, and has increased the venting pressure-relief valve, and protective effect has been played in personal safety.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the partial enlarged drawing of gauze and steel plate with holes;
Fig. 3 is a birds-eye view of the present invention.
The specific embodiment
With reference to accompanying drawing, the present invention includes manhole collar 1, manhole cover 8, aie escape valve 7 is installed on manhole cover 8.Aie escape valve 7 adopts ball valve.Two power assistant spring 9 are installed on the adapter shaft 10 of manhole collar 1 and manhole cover 8 symmetrically.Be provided with a slice gauze 6 in the bottom of manhole cover 8, gauze 6 has a steel plate with holes 5, and wherein gauze 6 plays ventilation but can not miss jar interior powder materials such as aluminium powder, and steel plate 5 with holes plays the effect of protection gauze.Manhole collar 1 bottom surface has one and the circular arc that is complementary of the circular arc of tank car car body.
During use, manhole collar 1 is welded on the tank car, manhole collar 1 and manhole cover 8 is fixed together with six roots of sensation bolt 3; 4 protections of one section steel pipe of every bolt 3 usefulness are lived; can only just can open with special spanner, play preventing that other people from malice opening manhole, between manhole collar 1 and manhole cover 8, be provided with seal ring 2., earlier six roots of sensation bolt is opened during thing in loading,, saved manpower, adorned behind the goods bolt is locked with special spanner owing to there is power assistant spring can open once carrying gently.Tank car in transportation because be heated, phase mutual friction meeting produces certain air pressure between object, when opening manhole cover at every turn, open venting ball valve venting release earlier, and then open manhole cover.
The present invention is applicable to that aluminium powder tank car, acid tanker, light oil tank wagon, oil tank car install and use.
