Fig. 1 is a schematic structural view of a sealing device for an inspection hole according to the present invention.
Labeled as: 1. tightening the bolts; 2. locking the nut; 3. a baffle plate; 4. a rubber plug; 5. a wedge block; 6. inspecting the hole; 7. a device or a pipe body.
Detailed Description
The utility model will be further illustrated by the following examples, which are intended only for a better understanding of the present invention and therefore do not limit the scope of the utility model.
Fig. 1 is a schematic structural view of a sealing device for an inspection hole according to the present invention.
The utility model provides a dismouting when sealing device for inspection hole installs on the inspection hole 6 of equipment or pipeline, makes things convenient for equipment or 7 inspection clearance of pipeline, specifically as shown in figure 1, including being located the rubber buffer 4 of inspection hole 6, the pulling locking mechanism of setting on rubber buffer 4 and the deformation prevention mechanism of setting in rubber buffer 4 top.
Wherein, in inspection hole 6 was arranged in to rubber buffer 4, the internal diameter of rubber buffer 4 was greater than the external diameter of inspection hole 6, and the rubber buffer 4 of being convenient for is plugged in inspection hole 6. The pulling locking mechanism comprises a wedge block 5, a tension bolt 1 which is arranged above the wedge block 5 and welded with the wedge block 5, and a locking nut 2 which is arranged at the free end of the tension bolt 1 and is in threaded connection with the tension bolt 1. The bottom of tie bolt 1 is connected the form for the welding with the top of wedge 5, is equipped with the internal thread on lock nut 2, is equipped with the external screw thread on tie bolt 1, and lock nut 2 is connected with tie bolt 1 through internal thread and external screw thread cooperation, locks tie bolt 1. The wedge-shaped block 5 is in a trapezoid shape, and two sides of the wedge-shaped block 5 are in contact connection with two sides of the bottom of the rubber plug 4. The wedge-shaped blocks 5 and the rubber plugs 4 are in axial symmetry, and the symmetry axes are the center lines of the inspection holes 6.
The anti-deformation mechanism comprises a baffle 3 which is positioned above the rubber plug 4 and below the locking nut 2; the top of rubber buffer 4 is connected with the bottom in close contact with at baffle 3, and the length at baffle 3 is the same with the length at 4 tops of rubber buffer, all is equipped with the through-hole on baffle 3 and the rubber buffer 4, and tie bolt 1 runs through the through-hole from the bottom up in proper order to pass rubber buffer 4 and baffle 3, lock tie bolt 1 through lock nut 2 above baffle 3 at last. The shape of the baffle 3 is also axisymmetric, and the symmetry axis is the central line of the inspection hole 6.
The sealing device for the inspection hole is used as follows: install rubber buffer 4 in inspection hole 6, outwards stimulate wedge 5 through tie bolt 1, extrude through wedge 5 and make rubber buffer 4 inflation, play sealed effect to inspection hole 6 after rubber buffer 4 inflation, lock tie bolt 1 through lock nut 2, baffle 3 can prevent rubber buffer 4's deformation, when this dismantlement sealing device, only need become flexible with lock nut 2, tie bolt 1 drives wedge 5 and withdraws from backward, sealing device can directly dismantle.
