Abstract
The utility model relates to a plugging clamp. A body (1) of the plugging clamp is composed of a first component (2) and a second component (3) which can be connected with each other. An exhaust hole (7) and a pillar hole (9) are formed in the upper portion of the second component (3), a valve pillar (4) is connected inside the pillar hole (9) of the second component (3) in a sleeved mode, an exhaust passage (6) is formed in the center of the valve pillar (4), a transverse passage (8) perpendicular to the central axis of the valve pillar (4) is further formed in the top of the exhaust passage (6), and when the valve pillar (4) is located at an exhaust position, the transverse passage (8) is communicated with the exhaust hole (7). Due to the fact that an exhaust process is added when the body (1) is connected, the pressure inside a pipeline rapidly decreases, the connection effect is reinforced, and the phenomenon of air leakage caused by untight connection of the body (1) is avoided.
Description
Technical field
The present invention relates to a kind of blocking clamper.
Background technique
Pipe plugging is a kind of common operation in pipe-line maintenance.General leak stopping often adopts blocking clamper.Fixture generally comprises two bodies, respectively two bodies is fixed on to the pipeline both sides of required leak stopping, and fixes with bolt during use.But, when running into pipeline and be high pressure pipe line, because overpressure is large, directly by the mode of two body engagement, need to overcome the pressure of pipeline leakage place, often engage imprecision, produce gas leak phenomenon.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model comprises a cylindrical body, and the pipeline of this body inner radius and required leak stopping is adaptive.This body comprise two can block each other and half-cylindrical parts, the inner radius of two parts is all suitable with pipeline, one of them parts is provided with exhaust port and post hole.Post is provided with valve rod in hole, valve rod is through these parts, one end of valve rod is fixedly connected with ball handle, valve rod center is provided with exhaust passage, the top of exhaust passage also has the crosspassage vertical with the central axis of valve rod, when valve rod is positioned at exhaust position, the exhaust port on crosspassage and body is on same level line, and crosspassage is connected with exhaust port.At the edge of body, be provided with suitable projection, each projection is provided with through hole, for using bolt to be fixed.
As improvement, exhaust passage is offered along the central axis of valve rod.
During use, first two bodies are fixed by bolted joints in pipeline both sides, used bolt to be fixed.Pull ball handle to make valve rod to exhaust position, now crosspassage is connected with exhaust passage again, and two intrinsic pressurized gas are discharged along exhaust port, and two body interior pressure reduce.After exhaust finishes, then valve rod is pushed, away from exhaust position.Like this, body interior and ambient atmosphere are isolated, have played the effect of leak stopping.
Owing to having increased an exhaust process when engaging body, manifold pressure is declined rapidly, strengthened joint effect, avoided the gas leak phenomenon producing because of body engagement imprecision.
Accompanying drawing explanation
Fig. 1 is after the utility model two bodies install, perspective view when valve rod is positioned at exhaust position.
Fig. 2 is the sectional view of the utility model valve rod.
Embodiment
The utility model comprises a cylindrical body 1, and the pipeline of this body 1 inner radius and required leak stopping is adaptive.This body 1 comprises two half-cylindrical first components 2 that can be engaged with each other and second component 3, and the inner radius of first component 2 and second component 3 is all suitable with pipeline, and wherein second component 3 is provided with exhaust port 7 and post hole 9.In post hole 9, be provided with valve rod 4, valve rod 4 is through these parts 3, one end of valve rod 4 is fixedly connected with ball handle 5, valve rod 4 centers are provided with exhaust passage 6, the top of exhaust passage 6 also has the crosspassage 8 vertical with the central axis of valve rod 4, when valve rod 4 is positioned at exhaust position, the exhaust port 7 on crosspassage 8 and parts 3 is on same level line, and crosspassage 8 is connected with exhaust port 7.At the edge of first component 2 and second component 3, be provided with in first suitable projection 10 and second projection 11, the first projection the 10 and second projections 11 and be all provided with through hole, for using bolt to be fixed.
As improvement, exhaust passage 6 is offered along the central axis of valve rod 4.
During use, first first component 2 and second component 3 are fixed by bolted joints in pipeline both sides, used bolt to be fixed.Pull ball handle 5 to make valve rod 4 to exhaust position, now crosspassage 8 is connected with exhaust port 7 again, and the pressurized gas in first component 2 and second component 3 are discharged along exhaust port 7, and first component 2 and second component 3 internal pressures reduce.After exhaust finishes, then valve rod 4 is pushed, away from exhaust position.Like this, first component 2 and second component 3 are inner isolated with ambient atmosphere, have played the effect of leak stopping.
Owing to having increased an exhaust process when engaging body 1, manifold pressure is declined rapidly, strengthened joint effect, avoided engaging because of first component 2 and second component 3 gas leak phenomenon that imprecisions produce.
