Abstract
The utility model provides an online plugging device of pipeline flange lid, including flange lid, fastening bolt, bracing piece, clamp bolt, clamp plate and sealed pad, a ring has been welded respectively at the bracing piece both ends, 2 at least and the supporting gland nut of clamp bolt of bracing piece middle part welding, and clamp bolt passes through gland nut to be installed on the bracing piece, and the clamp bolt lower extreme is equipped with a clamp plate, is equipped with sealed pad below the clamp plate, and the bracing piece both ends ring is connected on the flange lid through the fastening bolt who has the nut. The utility model discloses simple structure, convenient and practical, the operation of being convenient for can realize not moving fire and carry out the shutoff of blind flange leak source on line, reduces the loss of stopping production, guarantees operation safety, and does not influence going on in succession of production.
Description
Technical Field
The utility model belongs to coking pipeline field especially relates to an online plugging device of pipeline flange lid of not moving fire.
Background
The medium corrosiveness in the chemical equipment is generally stronger, so the condition of seepage often appears in the flange lid. Because chemical enterprises generally carry out continuous production for 24 hours, such as pipeline shutdown repair welding, the smooth production is seriously influenced; if dangerous media exist around the leakage point, the fire repair welding cannot be carried out, and once the fire repair welding is carried out, the risk of fire accidents is increased. How to improve the maintenance method of the leakage point and treat the leakage point under the condition of not stopping production and not firing is the key for thoroughly solving the problem.
Disclosure of Invention
The utility model aims at providing a simple and practical, the operation of being convenient for neither influences going on in succession of production, also can guarantee to overhaul the online plugging device of pipeline of operation safety.
Therefore, the utility model discloses the technical solution who takes does:
the utility model provides an online leaking stoppage device of pipeline flange lid, its characterized in that, including fastening bolt, bracing piece, clamp bolt, clamp plate and sealed the pad, a ring has been welded respectively at the bracing piece both ends, 2 at least gland nuts supporting with clamp bolt of bracing piece middle part welding, clamp bolt passes through gland nut and installs on the bracing piece, the clamp plate is equipped with to the clamp bolt lower extreme, be equipped with sealed the pad below the clamp plate, the ring is connected on the flange lid through the fastening bolt who has the nut at bracing piece both ends.
The utility model has the advantages that:
the utility model discloses simple structure, convenient and practical, the operation of being convenient for can realize not moving the fire and carry out the leaking stoppage of blind flange leak source on line, shortens processing time, reduces the loss of stopping production, not only can guarantee operation safety, does not influence going on smoothly in succession of production moreover.
Drawings
Fig. 1 is a schematic diagram of a pipeline online plugging device mechanism.
Fig. 2 is a top view of the support rod.
In the figure: the device comprises a flange cover 1, a fastening bolt 2, a support rod 3, a compression bolt 4, a circular ring 5, a pressure plate 6, a nut 7, a sealing gasket 8 and a compression nut 9.
Detailed Description
As shown in figure 1, the utility model discloses online plugging device of pipeline flange lid comprises fastening bolt 2, bracing piece 3, clamp bolt 4, ring 5, clamp plate 6, nut 7 and sealed pad 8. The support rod 3 has a diameter
The round steel of (1), it has a ring 5 that is used for connecting fastening bolt 2 to weld respectively at the both ends of bracing piece 3, 3 middle part both sides welding of bracing piece four gland nuts 9 supporting with gland bolt 4, gland nut 9 passes through threaded connection gland bolt 4, the lower extreme of gland bolt 4 is equipped with a thickness 4 mm's square clamp plate 6, be equipped with sealed pad 7 below clamp plate 6, be the leak source position of blind flange 1 below sealed pad 7 promptly, the outer lane of blind flange 1 has fastening bolt certainly, demolish two original fastening bolt, connect the ring 5 at 3 both ends of bracing piece on blind flange 1 through nut 7 and fastening bolt 2. The side length of the pressure plate 6 and the sealing gasket 8 is determined according to the length of the leakage point, but is required to be larger than the length of the leakage point.
When plugging, firstly, the leak point is covered by a sealing gasket 8; a pressure plate 6 is arranged on the sealing gasket 8; the support rod 3 and the flange cover 1 are fixed by the fastening bolt 2, so that the support rod and the flange cover are just above the leakage point; then the compression bolts 4 on the support rods 3 are symmetrically fastened to proper positions, the pressure plate 6 is ensured to be uniformly stressed and compressed on the sealing gasket 8, the online leakage stoppage of the flange cover 1 can be realized, and the sealing reliability of the leakage stoppage is ensured. If the leakage points are large or the number of the leakage points is large, the problem can be solved by increasing the number of the support rods 3, the pressure plates 6 and the sealing gaskets 8.
