Abstract
The utility model relates to a coke oven crude gas cutting device, including the cutting device body, this cutting device body is the circular blind plate of steel sheet material, there is the socket joint head at a cutting device body face down bonding, insert the connection nozzle stub that is used for fixed cutting device body outside the socket joint head, the other end of connecting the nozzle stub then links to each other with the discharge, opposite side at the cutting device body has then welded the handle locating lever, there is a hangers in the welding of the top of cutting device body, the hangers passes through the bolt and is connected the nozzle stub flange fixed continuously. Have sealed effectual characteristics, can stop raw coke oven gas ease outside connecting the nozzle stub, need not manual accurate control collecting main pressure, simultaneously the utility model discloses need not to move when the remaining old asbestos pad of clearance, being convenient for, just factor of safety is higher in the clearance operation.
Description
Technical field
The utility model belongs to coking equipment recovery technique field, relates to a kind of coal oven dithio-gas shut-off device.
Background technology
Valve body is a kind of important coal oven dithio-gas equipment leading out, and its Main Function is the connection and the cut-out that realize raw gas between upcast and effuser.Valve body top is connected with sleeve with bridge tube, and bottom is connected short tube by flange with effuser and is connected.In process of production, expand by coking furnace shaft, the factor impacts such as ammoniacal liquor, tar corrosion, coke oven valve body can crack, and even ftractures.For avoiding valve body cracking to cause potential safety hazard to coke oven production, coke oven valve body should be changed in time.Key and the difficult point of changing valve body are to dismantle old valve body, the collecting main pressure installed in new valve body process controls.Especially, when clearing up effuser and connecting old asbestos pad remaining on short tube flange, prevent raw gas from connecting short tube from effuser and escape most important.The iron blind plate generally adopted at present needs when the old asbestos pad of cleaning residual to move, higher to the accuracy requirement of manual domination set tracheal pressure.If collecting main pressure is comparatively large, still has a large amount of raw gas and escape from effuser connection short tube, change operation to valve body and bring larger potential safety hazard.
Utility model content
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of coal oven dithio-gas shut-off device, and it is lower to the accuracy requirement of manual domination set tracheal pressure, is convenient to old pad cleaning work, and can effectively prevent coke oven collecting main raw gas from escaping.
The utility model solves the technical scheme that its technical problem adopts: a kind of coal oven dithio-gas shut-off device, comprise shut-off device body, this shut-off device body is the circular blind plate of steel plate material, socket joint head is welded with in shut-off device body side, the connection short tube for fixing shut-off device body is inserted with outside socket joint head, the other end connecting short tube is then connected with effuser, handle backstay is then welded with at the opposite side of shut-off device body, above shut-off device body, be welded with a hangers, hangers by bolt be connected short tube flange and be fixedly linked.
Have high temperature resistant woven asbesto at described shut-off device body and socket joint head outer wrap, this is high temperature resistant woven asbesto is also fixed through circular hole by copper cash, can effectively prevent in shut-off device use procedure be connected short tube generation direct collision.
A handle is socketed with, remote manipulation shut-off device when being convenient to lift by crane old valve body in the outside of described handle backstay.
The beneficial effects of the utility model are: the feature with good sealing effect, raw gas can be stopped escape from connection short tube, without the need to manual accurately domination set tracheal pressure, the utility model is when the old asbestos pad of cleaning residual without the need to moving simultaneously, is convenient to cleaning operation and safety coefficient is higher.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view in Fig. 1;
Fig. 3 is embodiment schematic diagram of the present utility model.
In figure: 1-shut-off device body, 2-socket joint head, 3-is high temperature resistant woven asbesto, 4-copper cash, 5-circular hole, 6-hangers, 7-handle backstay, 8-handle, 9-bolt, 10-connects short tube flange, and 11-connects short tube, 12-effuser.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
See Fig. 1 ~ Fig. 3, a kind of coal oven dithio-gas shut-off device, comprise shut-off device body 1, this shut-off device body 1 is the circular blind plate of steel plate material, socket joint head 2 is welded with in shut-off device body 1 side, high temperature resistant woven asbesto 3 is had at shut-off device body 1 and socket joint head 2 outer wrap, this is high temperature resistant, and woven asbesto 3 is also fixed through circular hole 5 by copper cash 4, can effectively prevent in shut-off device use procedure be connected short tube 11 direct collision occur, the connection short tube 11 for fixing shut-off device body 1 is inserted with outside socket joint head 2, the other end connecting short tube 11 is then connected with effuser 12, handle backstay 7 is then welded with at the opposite side of shut-off device body 1, a handle 8 is socketed with in the outside of handle backstay 7, remote manipulation shut-off device when being convenient to lift by crane old valve body, a hangers 6 is welded with above shut-off device body 1, hangers 6 by bolt 9 be connected short tube flange 10 and be fixedly linked.
During actual use, when old valve body hangs connection short tube 11, immediately by handle 8 remote manipulation shut-off device, socket joint head 2 is inserted and connects in short tube 11, manually withstand shut-off device body 1; After old valve body hangs, with bolt 9 by hangers 6 be connected short tube flange 10 and be connected, fix shut-off device body 1, then unload lower handle 8, by asbestos seal shut-off device body 1 surrounding, guarantee to escape without raw gas.
The utility model has the feature of good sealing effect, raw gas can be stopped escape from connection short tube 11, without the need to manual accurately domination set tracheae 12 pressure, the utility model is when the old asbestos pad of cleaning residual without the need to moving simultaneously, is convenient to cleaning operation and safety coefficient is higher.
