(7) personnel's manual operation left hand valve core holder 8, clamps old spool 6, is unclamped by new spool 7 simultaneously;
(8) right hand valve core support 5 moves to container body 1 center, and new spool 7 is sling by gravity type Automatic hook block 3, and spool bracket institution 5 returns original position;
(9) gravity type Automatic hook block 3 is descending, new spool 7 down-to-position, and gravity type Automatic hook block 3 and spool 7 depart from and go upward to above horizontal small car mechanism 11;
(10) horizontal small car mechanism 11 moves to below gravity type Automatic hook block 3, and gravity type Automatic hook block 3 picks up double cover doors 10, and original position is return by horizontal small car mechanism 11;
(11) gravity type Automatic hook block exercises double cover doors 10 return 3 times, and gravity type Automatic hook block 3 and double cover doors 10 depart from and go upward to the position of original state;
(12) switching tools of the double-canopy sealing mechanism 10 of personnel's manual operation, makes upper and lower cover throw off, meanwhile, the base plate of upper cover and container body 1 is locked, lower cover and wear ground valve valve lock;
(13) maintenance container for valve power-off, utilizes factory building crane to be hung away by the maintenance container that old spool is housed, and the upper operating mechanism of wearing ground valve is reinstalled;
(14) site clearing, this stage has worked.
Maintenance container for valve of the present invention, α sealing and the gamma shielding of overall process can be realized during operation, conscientiously the safety of operating personnel and peripheral environment can be ensured, container body inner chamber is low by the pollution level of old spool place environmental gas, reduce the cleaning frequency of container body inner chamber, and single docking just can realize the replacing to wearing ground valve core, decrease transhipment number of times and the task amount of associative operation, therefore there is reliable in function, simple to operate, human intervention is few, the speed of stable drive, movement parts is relatively mild, without the advantage of thump, long service life.
It should be noted that; above-mentioned specific embodiment is only exemplary; under above-mentioned instruction of the present invention, those skilled in the art can carry out various improvement and distortion on the basis of above-described embodiment, and these improve or distortion all drops in protection scope of the present invention.It will be understood by those skilled in the art that specific descriptions are above to explain object of the present invention, not for limiting the present invention.Protection scope of the present invention is by claim and equivalents thereof.
