Abstract
The invention relates to a plugging device. The plugging device comprises a pull rod, a base and a pressing block; one end of the pull rod penetrates through the base and is fixed through a locking nut; the pressing block is arranged on the pull rod in a sleeved mode and can vertically move along threads of 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 firstly inserted into a flow channel of a pipeline, then a pressing rod can be unscrewed out when the pull rod rotates, and therefore the pressing block tightly presses the drum-shaped rubber ring and enables the drum-shaped rubber ring to deform; the drum-shaped rubber ring can plug the flow channel; the outer portion of the end portion of the base and the outer portion of the end portion, adjacent to the end portion of the base, of a pressing board are respectively provided with a notch portion; the drum-shaped rubber ring is arranged between the notch portion of the base and the notch portion of the pressing board, and therefore the thickness of the drum-shaped rubber ring can be reduced, deformation is easy, and operation is easier. The plugging device is simple in structure, convenient to use, and large in pressure which can be borne by the plugging device.
Description
Technical field
The present invention 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 of the inwall of the surface with tapering of tapered plug and the fluid passage on pipeline to realize the obstruction of convection cell passage, this tapered plug in use, produce pretightening force between the inwall that needs to use larger power to make tapered plug and 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.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art 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 used in the present invention is: a kind of plugging device comprises pull bar, base, briquetting; One end of described pull bar passes base and fixes with locking nut; Described briquetting is set on pull bar, and can move up and down along the screw thread on pull bar; Be provided with the cydariform rubber ring between described base and briquetting; 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 of notch part on base and pressing plate.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Plugging device of the present invention, during use, first insert in the fluid passage of pipeline, when pull bar rotates, depression bar can be screwed out, thereby make briquetting compress the cydariform rubber ring, makes the distortion of cydariform rubber ring; Described cydariform rubber ring can be by the 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 of notch part on base and pressing plate, and the thickness of drum-shape sealing ring can reduce like this, distortion easily, thereby make operation easier; The present invention is simple in structure, easy to use, and the pressure that can bear is large.
