Abstract
The utility model provides a tank cover of a yellow phosphorus tank wagon, relating to a tank cover of a railway freight tank wagon. The utility model comprises a converse Y-shape hole seat, an outer cover movably connected with the converse Y-shape hole seat, and an inner cover arranged inside the converse Y-shape hole seat. The key technique of the utility model is that: the inner cover is detachable; an aeration valve, a charging hole and a compressing device are arranged on the inner cover. The utility model has the advantages that: protective gas can be conveniently charged through the gas valve, while the charging hole with a compressing cover can provide convenience for the charging of various inflammable goods, moreover, the sealing of a tank body can effectively prevent the protective gas from leaking out through a converse Y-shape hole during long-term use; the detachable inner cover meets the requirement of users on cleaning the inner wall of the tank body. Therefore, the utility model not only meets the common operation needs of the converse Y-shape hole, but also considers the special needs for loading and transporting inflammable goods.
Description
Technical field
The utility model relates to a kind of cover of tank car, especially the cover of railway freight tank car.
Background technology
As everyone knows, yellow phosphorus is the cream-yellow waxy body under the normal temperature normality, and molten point is 44.1 ℃; it is a kind of one-level dangerous material of very easily oxidation, burning in air; therefore during at transportation yellow phosphorus, all in tank body, fill atmosphere gas, at existing railway yellow phosphorus tank car so that yellow phosphorus and air completely cut off.But because existing cover is poorly sealed, cause the leakage of atmosphere gas, constitute potential safety hazard.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of cover of yellow phosphorus tank car, adopts technical scheme as follows:
It comprises manhole collar 1, with the movable enclosing cover 2 that links of manhole collar, and is installed in inner cap 3 in the manhole collar, and its gordian technique is: inner cap 3 is for detachable, in cover and be provided with charging valve 4, charging door 5 and pinch device 6.
The utility model compared with prior art has following advantage: can fill atmosphere gas easily by gas valve, and the charging door of band friction top can make things convenient for filling of various inflammable freightes, and tank body sealed, can effectively avoid in long-term use, atmosphere gas leaks by manhole; Detachable inner cap has satisfied the user again and has carried out the requirement of inner tank wall washing and cleaning operation.So both satisfy manhole general job needs, considered the special requirement of inflammable freight loading, transportation again.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, the 1st, manhole collar, the 2nd, enclosing cover, the 3rd, inner cap, the 4th, charging valve, the 5th, charging door, the 6th, pinch device, the 6.1st, friction top, the 6.2nd, crossbeam, the 6.3rd, clamp nut, the 6.4th, fastening screw, the 6.5th, hasp.
The specific embodiment
Referring to accompanying drawing, it comprises, with the movable enclosing cover 2 that links of manhole collar, and is installed in inner cap 3 in the manhole collar, and its gordian technique is: inner cap 3 is for detachable, in cover and be provided with charging valve 4, charging door 5 and pinch device 6; Pinch device 6 is made up of friction top 6.1, crossbeam 6.2, clamp nut 6.3, fastening screw 6.4, hasp 6.5, friction top is installed on the crossbeam 6.2 by fastening screw 6.4 and clamp nut 6.3,3 movable bindings of crossbeam one end and inner cap, the other end can be installed in the hasp 6.5 that covers be interlocked; When crossbeam 6.2 fastened with hasp 6.5, friction top 6.1 just in time covered on the charging door 5.
The utility model principle of work is as follows: by charging valve 4 atmosphere gas is charged in the tank body earlier; discharge the air in the tank body; then crossbeam 6.2 and hasp 6.5 are fastened; this moment, friction top 6.1 just in time covered on the charging door 5; by adjusting clamp nut 6.3, make friction top 6.1 and inner cap 3 combine closely, sealing charging door 5; shut enclosing cover 2 at last, finish charging work.
