Abstract
The utility model relates to a plugging device. The plugging device comprises a pull rod, a base and a pressing block, wherein one end of the pull rod penetrates through the base and is fixed through a lock nut, the pressing block is arranged on the pull rod in a sleeved mode, and can vertically move along threads formed in the pull rod, a drum-shaped rubber ring is arranged between the base and the pressing block, and a handle is arranged on the upper end portion of the pull rod. When the plugging device is used, the plugging device is inserted into a fluid channel of a pipeline, when the pull rod rotates, a pressing rod can get out in a rotating mode so that the pressing block can tightly press the drum-shaped rubber ring, and the drum-shaped rubber ring deforms; the drum-shaped rubber ring can plug the fluid channel; notch portions are arranged outside the end portion, adjacent to a pressing plate, of the base and the end portion, adjacent to the base, of the pressing plate respectively; due to the fact that the drum-shaped rubber ring is arranged between the notch portion arranged on the base and the notch portion arranged on the pressing plate, the thickness of the drum-shaped sealing ring can be reduced, deformation can be easily carried out, and operation can be easier; the plugging device is simple in structure and convenient to use, and can bear high pressure.
Description
Technical field
The utility model relates to a kind of improvement of pipeline, refer in particular to a kind of simple in structure, easy to use, and the large plugging device of the pressure that can bear.
Background technique
The shutoff of common pipeline, the general tapered plug that adopts, utilize the close contact with the surface of tapering and the inwall of the fluid passage on pipeline of tapered plug to realize the obstruction of convection cell passage, this tapered plug in use, need to use larger power to make to produce pretightening force between tapered plug and the inwall of fluid passage, can overcome the hydrodynamic pressure in fluid passage; Hydrodynamic pressure in fluid passage is larger, and the pretightening force of tapered plug is while being not enough to overcome, and this tapered plug is not too applicable; For this reason, we have researched and developed a kind of simple in structure, easy to use, and the large plugging device of the pressure that can bear.
Model utility content
The utility model object is in order to overcome the deficiencies in the prior art, to provide a kind of simple in structure, easy to use, and the large plugging device of the pressure that can bear.
For achieving the above object, the technical solution adopted in the utility model is: a kind of plugging device, comprises pull bar, base, briquetting; One end of described pull bar is passed base and is fixed with locking nut; Described briquetting is set on pull bar, and can move up and down along the screw thread on pull bar; Between described base and briquetting, be provided with cydariform rubber ring; The upper end portion of described pull bar is provided with handle.
Preferably, the upper surface of described briquetting is provided with sheath, on described sheath endoporus, is provided with internal thread, and described sheath is arranged on pull bar, and can move up and down along the screw thread on pull bar.
Preferably, on the lower surface of described base, be provided with groove, described locking nut is arranged in groove; The opening portion of described groove is provided with cover plate.
The outside of the end that preferably, described base and pressing plate are adjacent arranges respectively notch part; Described cydariform rubber ring is arranged between the notch part and the notch part of pressing plate on base.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Plugging device described in the utility model, during use, first inserts in the fluid passage of pipeline, when pull bar rotates, depression bar can be screwed out, thereby make briquetting compress cydariform rubber ring, makes the distortion of cydariform rubber ring; Described cydariform rubber ring can be by fluid passage shutoff; The outside of the end that described base and pressing plate are adjacent arranges respectively notch part; Described cydariform rubber ring is arranged between the notch part and the notch part of pressing plate on base, and the thickness of drum-shape sealing ring can reduce like this, and distortion is easy, thereby makes operation easier; The utility model is simple in structure, easy to use, and the pressure that can bear is large.
