Abstract
The utility model discloses a pipe orifice plugging device, it has the twist grip through bolt fixed mounting including sealed valve rod, the left side end of sealed valve rod, and sealed valve rod passes the central threaded hole on chassis, and the chassis is passed through the bolt fastening with chuck device and is linked to each other, and chuck device's three jack catch is through the outer wall of drive hand wheel chucking pipeline, and the right side of sealed valve rod is terminal for the toper section, and the outer surface set of toper section has toper rubber circle, and toper rubber circle passes through fastening nut fixed mounting. This plugging device can guarantee the shutoff effect, prevents that it from taking place to leak, improves sealed reliability.
Description
Technical field
This utility model belongs to pipe plugging technical field, especially a kind of mouth plugging apparatus。
Background technology
In pipeline construction process, sometimes for pipeline being carried out pressure testing and upkeep operation, now it is accomplished by the high pressure water flowing section of pipeline is blocked, consequently facilitating the upkeep operation of pipeline, existing frequently-used blocking technology also exists leakage, the not tight defect of closure, and plugging operations is inconvenient, plugging effect is difficult to well be ensured, it is therefore desirable to adopt Novel sealing blocking method to carry out closure operation。
Utility model content
The purpose of this utility model is to provide a kind of mouth plugging apparatus, and this plugging device ensure that plugging effect, it is prevented that it leaks, and improves the reliability sealed。
In order to realize above-mentioned technical characteristic, the technical solution adopted in the utility model is: a kind of mouth plugging apparatus, it includes sealed valve stem, the left distal end of sealed valve stem is bolted and is provided with rotary handle, the screwed hole of centre on sealed valve stem traverse chassis, chassis is bolted with chuck assembly and is connected, three claws of chuck assembly are by driving the outer wall of handwheel clamping pipeline, the right end of sealed valve stem is conical section, the outer surface of conical section is set with cone rubber circle, and cone rubber circle is fixedly mounted by clamp nut。
The center processing on described chassis has screwed hole of centre, and screwed hole of centre coordinates with sealed valve stem composition screw-driven, and the uniform processing of excircle on chassis has a multiple screwed hole。
Described chuck assembly includes chuck, the uniform claw that is provided with on the outer wall of chuck, and the uniform processing of excircle of chuck has multiple No. two screwed holes, and a corresponding threaded holes on No. two screwed holes and chassis closes fixed installation。
The center processing of described chuck assembly has centre bore, and centre bore coordinates with sealed valve stem, facilitates it to pass。
This utility model has the advantages that:
When pipeline is blocked by needs, first the claw of chuck assembly is installed on the outer wall of pipeline, then passing through driving handwheel makes claw that pipeline to be clamped claw applying power, then at manual rotation rotary handle, sealed valve stem is driven by rotary handle, and then promoted to the inside of pipeline by sealed valve stem by screw-driven cooperation, and then cone rubber circle is made to block the outlet of pipeline。
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail。
Fig. 1 is this utility model front view。
Fig. 2 is the left view on this utility model chassis。
Fig. 3 is this utility model chuck assembly structural representation。
In figure: sealed valve stem 1, rotary handle 2, chassis 3, driving handwheel 4, chuck assembly 5, claw 6, conical section 7, cone rubber circle 8, clamp nut 9, pipeline 10,301, screwed hole 302 of screwed hole of centre, centre bore 501,502, No. two screwed holes 503 of chuck。
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further。
As Figure 1-3, a kind of mouth plugging apparatus, it includes sealed valve stem 1, the left distal end of sealed valve stem 1 is bolted and is provided with rotary handle 2, the screwed hole of centre 301 on sealed valve stem 1 traverse chassis 3, chassis 3 is bolted with chuck assembly 5 and is connected, three claws 6 of chuck assembly 5 are by driving the outer wall of handwheel 4 clamping pipeline 10, the right end of sealed valve stem 1 is conical section 7, the outer surface of conical section 7 is set with cone rubber circle 8, and cone rubber circle 8 is fixedly mounted by clamp nut 9。
Further, the processing of the center on described chassis 3 has screwed hole of centre 301, screwed hole of centre 301 to constitute screw-driven with sealed valve stem 1 to coordinate, and the uniform processing of excircle on chassis 3 has a multiple screwed hole 302。
Further, described chuck assembly 5 includes chuck 502, the uniform claw 6 that is provided with on the outer wall of chuck 502, and the uniform processing of excircle of chuck 502 has multiple No. two screwed holes 503, and a screwed hole 302 on No. two screwed holes 503 and chassis 3 matches fixed installation。
Further, the center processing of described chuck assembly 5 has centre bore 501, and centre bore 501 coordinates with sealed valve stem 1, facilitates it to pass。
Work process of the present utility model and operation principle be:
When pipeline is blocked by needs, first the claw 6 of chuck assembly 5 is installed on the outer wall of pipeline 10, then pass through driving handwheel 4 claw 6 applies power to make claw 6 that pipeline 10 to be clamped, then at manual rotation rotary handle 2, sealed valve stem 1 is driven by rotary handle 2, and then promoted to the inside of pipeline 10 by sealed valve stem 1 by screw-driven cooperation, and then cone rubber circle 8 is made to block the outlet of pipeline 10。
