Abstract
The utility model provides a quick non-welding plugging device of a pipeline opening, and relates to a plugging device of a pipeline opening. The plugging device comprises a plugging cover. The plugging device is technically characterized by comprising a jacking and bracing bracket, wherein one end of a bracket screw rod of the jacking and bracing bracket is provided with bracket support legs of a connecting rod structure, the front end of each bracket support leg is provided with a jacking and bracing support leg, the bracket screw rod is provided with an expanding screw cap near the bracket support legs, and the other end of the bracket screw rod is provided with the plugging cover. The plugging device has the beneficial effects that the plugging device is suitable for plugging the pipeline opening under various environments (including underwater environment), the safety and the reliability are realized, and the installation and the detachment are quick and convenient; and more importantly, the welding is avoided, and the repeated use is realized.
Description
Technical field:
The quick solderless blocking device of a kind of mouth of pipe relates to a kind of blocking device of the pipeline mouth of pipe.
Background technique:
At present, in the engineering construction in the various pipes installation process, treat the mounting pipe road junction and install after the protection of pipeline opening to be come into operation pay much attention to, adopt the shutoff of welding closure plate usually.But the welding closure plate shutoff expense of taking a lot of work is expected, limited by welding condition, the shutoff of the mouth of pipe especially under water, and it is very big to weld shutoff operating technology difficulty under water.
Summary of the invention:
Problem to be solved in the utility model is exactly to provide a kind of just need not weld can be to the blocking device of pipeline mouth of pipe shutoff protection at above deficiency.Its technological scheme is as follows:
It comprises capping, its key technology is also to comprise shoring support, shores support and be the support supporting leg in support screw one end installing connecting rods structure, and support supporting leg front end is to shore leg, on support screw, near the bracket leg leg expansion nut is installed, at the other end of support screw capping is installed.
Compared with prior art, the beneficial effect that the utlity model has is:
The utility model can use the mouth of pipe shutoff of various environment (comprising underwater environment), and safety is firm, and peace is torn open quick and convenient, and its great advantage is to weld, and is reusable.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is that Fig. 1 uses the status architecture schematic representation;
Fig. 3 is that the utility model uses the state perspective view.
Embodiment:
Referring to Fig. 1-Fig. 3, the utility model comprises capping 6, its key technology is also to comprise shoring support, shore support and be the support supporting leg 1 in support screw 10 1 end installing connecting rods structures, support supporting leg 1 front end is to shore leg 2, near bracket leg leg 1 expansion nut 12 is installed on support screw 10, at the other end of support screw 10 capping 6 is installed, support screw is firmly fixed at the mouth of pipe with capping.
Shoring bonding bath mat 4 on the leg 2, anti-skidding when being convenient to contact with the mouth of pipe.
Paste rubber water stop ring 5 in that capping is inboard, so that during mouth of pipe shutoff under water, play good shutoff stagnant water effect.
Be provided with water-filling valve 8 at capping 6, so that when negative pressure causes capping be difficult for to take out in the pipe, the easy disassembly capping.
The utility model working procedure is as follows:
According to the internal diameter size of the mouth of pipe of pipeline 3, the expansion nut 12 of support is shored in rotation, and support supporting leg 1 is adjusted to suitable size.To shore the mouth of pipe interior (it is concordant with the mouth of pipe to launch nut 12) that support stretches into pipeline 3, rotary expansion nut 12 makes support supporting leg 1 launch to hold out against tube wall again.
The water-filling valve 8 of capping 6 is placed open mode, capping 6 is installed on the support screw 10, put on and the nut 11(that is tightened makes rubber water stop ring 5 that the decrement of any be arranged), close water-filling valve 8, support screw 10 is firmly fixed at the mouth of pipe with capping 6.
The affirmation pipeline valve is closed before the dismounting.Open water-filling valve 8 during dismounting earlier, in order to manage interior water-filling, concora crush; Rotation hold-doun nut 11 is pulled down capping 6; The expansion nut 12 of support is shored in rotation, regains support supporting leg 1, removes and shores support.
Operation at sea and underwater operation are basic identical, have only lacked the action of water-filling valve 8.
