Embodiment
Like Fig. 2, shown in Figure 3, be respectively the three-dimensional combination figure and the exploded view of a kind of device for plugging valves of pressure vessel of the present invention, it comprises cover body 5 and 6 two parts of pedestal, wherein:
Described cover body 5 comprises the enclosed hood 51 and upper cover plate 52 that one connects; Described enclosed hood 51 is provided with an opening; Described upper cover plate 52 is connected the aperture position of described enclosed hood 51, on described upper cover plate 52, is provided with several attachment holes 521, is used for being fastenedly connected with pedestal 6; In addition, in order to guarantee the airtight effect of leakage-baffling device, in enclosed hood 51, also be provided with seal ring 53 (seeing also Fig. 4);
Described pedestal 6 comprises the left base 61 and right base 62 that is oppositely arranged; Each is extended with a lower shoe 63 relatively on left side base 61 and the right base 62; Described lower shoe 63 is to be used for being against on the bottom surface of described valve fitting seat 3, for forming a stable force bearing point; Two ends at described left base 61 and right base 62 are respectively equipped with horizontal attachment hole 611,621; After passing described horizontal attachment hole 611,621 with the bolt (not shown); Cover upper cap nut (not shown) can connect as one left base 61 with right base 62; In order to adapt to the profile of valve fitting seat 3, in the present embodiment, after the breach 631 that extends 631, two the positions correspondences that respectively open a gap on the lower shoe 63 that is provided with relatively is fastened togather, can a valve fitting seat 3 firmly be surrounded; Also be respectively equipped with several vertical attachment holes 612,622 on described left base 61 and the right base 62; Its position respectively with upper cover plate 52 on the position of attachment hole 521 corresponding; After several bolt (not shown) pass described attachment hole 521 and vertical attachment hole 612,622; Cover upper cap nut (not shown) can connect as one cover body 5 and pedestal 6.
In case stop valve on the pressurized container 2 just can use above-mentioned device for plugging valves of pressure vessel I type to carry out leak stopping because valve body breaks or seal ring is aging etc. former thereby leak, the step of its operation is following:
As shown in Figure 4, left base 61 is enclosed within the left and right sides of valve fitting seat 3 respectively with right base 62, and described lower shoe 63 is embedded between valve fitting seat 3 and the pressurized container 1;
After passing described horizontal attachment hole 611,621 with bolt then, overlap upper cap nut again and give fasteningly, left base 61 and right base 62 are connected as one;
Then, cover body 5 is buckled on the pedestal of left base 61 and right base 62 compositions, and makes seal ring 53 driving fits between enclosed hood 51 and valve fitting seat 3, so that valve fitting seat 3 and stop valve 2 are sealed in the enclosed hood 51;
At last; After using bolt to pass described attachment hole 521 and vertical attachment hole 612,622; Overlap upper cap nut again and give fasteningly, cover body and pedestal are connected as one, and compresses seal 53; The hazardous chemical gas that leakage is come out from stop valve 2 all is sealed in the described enclosed hood 51, can reveal away.
Handle through above-mentioned leak stopping, just can under safer condition, wait for rescue the arrival of troop, the pressurized container that perhaps will temporarily settle out is transported to repair location, carries out final safe handling.
From the above, of the present invention simple in structure, easy to operate, good sealing effect, the problem of pressure container valve leak well.
Certainly, above-mentioned only is a preferred embodiment of the present invention, and the alternative that much is equal to can also be arranged:
Can also set up the drain valve (not shown) on the described cover body 5, thereby the hazmat in the pressurized container reclaimed through drain valve; And, can also set up the GAUGE CONNECTOR (not shown) on the described cover body 5, connect after the pressure gauge, just can measure the force value in the cover body 5 easily.
In addition, seeing also shown in Figure 5ly, is another embodiment of the present invention, and sometimes, two stop valves 2 on the pressurized container 1 leak simultaneously, in order to practice thrift plugging time, just can use this mode of execution.In this mode of execution; The difference of device for plugging valves of pressure vessel is: cover body 5 is provided with two enclosed hoods 51; The position of two stop valves 2 on the position of two enclosed hoods 51 and the pressurized container 1 is corresponding; And set lower shoe 63 can prop up the bottom surface of two valve fitting seats 3 simultaneously on the pedestal 6, described pedestal 6 simultaneously with cover body 5 on two enclosed hoods 51 connect airtight, two valve fitting seats 3 on the pressurized container 1 are together sealed.This embodiment is all identical with other modular construction of a last embodiment, does not repeat them here.Obviously, use this mode of execution, can once block the leakage of two stop valves, accelerated blocking speed.
In addition, seeing also shown in Figure 6ly, is another embodiment of the present invention, corresponding to the situation that has attachment hole on the valve fitting seat 3.For example, the stop valve 2 at horizontal tank car top is installed on the valve fitting seat 3 through several fixing bolts 71 that pass attachment hole exactly, and valve fitting seat 3 is welded on the mountion plate 8 at horizontal tank car top again.The top of the horizontal tank car of this structure bumps with limit for height thing such as viaduct easily, and causes stop valve 2 to be revealed, and while fixing bolt 71 is generally severed, and stays the length of 2～4 pitch at valve fitting seat upper surface.Because horizontal tank car top do not have force bearing point, traditional blocking method be with chain around a horizontal jar circle, again Plugging device is fixed, exist fixing not really, the problem of complicated operation.The present invention is used for handling this leakage, then has advantage easily and efficiently.
At this time, it is as shown in Figure 6 to use the present invention to carry out the situation of leak stopping, remains pedestal 6 around valve fitting seat 3 location, then cover body 5 is covered on the top of stop valve 2, and is fixedly connected with pedestal 6.Difference is: leak from bolt 71 in order to prevent pressurized gas; On seal ring 53, offer several tanks 531; Place wherein end for bolt 71; And the upper surface of the lower surface of seal ring 53 and valve fitting seat 3 connects airtight, thereby has effectively completely cut off the escape path of pressurized gas, reaches good sealing effect.
Handle through above-mentioned leak stopping, just can the leakage of horizontal tank car temporarily be settled out, horizontal tank car is transported to specifies the maintenance place then, carry out final safe handling at that.
Can know from foregoing; The present invention is applicable to that the situation of leaking takes place the valve body (like stop valve, safety valve etc.) on the pressurized container; Be centered around the both sides of valve fitting seat with pedestal of the present invention, prop up the bottom surface of valve fitting seat, form a stable force bearing point with the lower shoe of pedestal; Then cover body is covered on pedestal, form tight sealing.Run out of outside the enclosed hood thereby prevent to leak in the valve body gas that comes out, reach the purpose of urgent leak stopping.
Certainly; Below only be several preferred embodiments of the present invention; Can not cover the mode that might implement of the present invention fully, those skilled in the art rely on common practise, perhaps under the experiment of limited number of times; The simple mode of execution that all can obtain a lot of alternate embodiments or extend out all should be considered to belong under the inventive concept of the present invention.
