Background
The fluid medium is transported under pressure in a liquid medium transportation mode commonly used by traditional enterprises, and a fluid pipeline has a hollow section and is used for transporting oil, natural gas, coal gas, water and certain solid materials. At present, the pipeline connection of the pressurized fluid is mainly carried out through a flange plate and a threaded opening. In the prior art, after a pipeline connected with a threaded port leaks, a binding, isolating or manufacturing clamp is adopted to wrap a leakage point and establish a sealing cavity, so that the leakage part of the pipeline is sealed, but when a pipeline interface with fluid in the pipeline is sealed, a large amount of fluid is sprayed when the pipeline is separated for operation, so that the waste of resources is caused; in addition, when the sealing tape is directly wound on the outer side of the pipeline for plugging, firstly, the sealing effect is poor, and secondly, the aging is easy, so that the service life is influenced; the welding requires a special tool for operation, which is troublesome. Therefore, there is a need for improvements in the prior art.

In order to achieve the above object, the utility model provides a following technical scheme: the rigid plugging device is characterized in that the shell is formed by combining two identical half shells, a gland with a second pipeline groove is arranged in the first pipeline groove at the two ends of each half shell, a sealing ring matched with the pressurized fluid pipeline is arranged in the second pipeline groove of the gland, a first semicircular flange plate is arranged at the outer end of the first pipeline groove, and a plurality of first screw holes are formed in the first semicircular flange plate so as to wrap and fix the two half shells at the leakage position of the pressurized fluid pipeline, then the two ends of the shell are sealed through the gland and the sealing ring, and the plugging of the leakage position of the pressurized fluid pipeline is completed.
The outer end of the gland is provided with a second semicircular flange plate, the second semicircular flange plate is provided with a plurality of second screw holes matched with the plurality of first screw holes in the first semicircular flange plate at the outer end of the first pipeline groove of the shell, and each second screw hole is internally provided with a screw or a bolt and a nut so that the gland can be fixed on the shell through the screw or the bolt and the nut.
A groove is symmetrically formed in one of the semi-rectangular body combination surfaces of the shell, a protrusion matched with the groove is symmetrically formed in the other semi-rectangular body combination surface of the shell, a corresponding sealing gasket is arranged in the groove, the groove and the protrusion are located on the outer side of the cavity, and therefore after the two semi-rectangular bodies are combined, the two semi-rectangular bodies are located through the groove and the protrusion which are arranged mutually and sealed through the sealing gasket.
The two half shells of the shell respectively comprise a cavity which is trapezoidal, the left end and the right end of the cavity are respectively provided with a first pipeline groove communicated with the cavity, the first pipeline groove is provided with a semi-cylindrical shape matched with the pressurized fluid pipeline, the front side and the rear side of the cavity are respectively provided with a rectangular flange, the rectangular flange is provided with a plurality of screw holes, and each screw hole is internally provided with a bolt and a nut, so that after the two half shells are wrapped on the pressurized fluid pipeline and folded, the two half shells are connected into a sealed whole through the screw holes on the rectangular flange and the bolts and nuts in the screw holes, and further the leakage part of the pressurized fluid pipeline is blocked.
Compared with the prior art, the utility model discloses following beneficial effect has: by adopting the technical scheme, the two half shells can be quickly wrapped and fixed behind the leakage part of the pressurized fluid pipeline, the two ends of the shell are sealed through the gland and the sealing ring, the blocking of the leakage part of the pressurized fluid pipeline is completed, the pipeline does not need to be separated or welded, the operation is simple, the sealing effect is good, the working efficiency can be improved, the waste of resources can be reduced, and the working efficiency is high.
