Description
Technical field
The present invention relates to a kind of device for being used to carrying out the flange hole on container into quick blocking.
Background technology
Pressure vessel is when carrying out the water pressure test, it is necessary to each flange port on container be blocked, then to container
Interior water filling pressurization is checked.
At present, before pressure vessel carries out the water pressure test, it is to use blind plate method that closure is carried out to each flange port on container
Orchid, makes blank flange be fastenedly connected with the flange on container by flange bolt, with blank flange by container
Flange port carries out sealing blocking, carries out the water pressure test afterwards.
This sealing means using blank flange, that is, time-consuming and laborious, often due to screwing screwing for each flange bolt
Flange port sealing leak when power difference causes pressure testing on container, and after test pressure is more than 20MPa, by reason of heavy pressure, this
Kind is not just applied to using the sealing means of blank flange.
The content of the invention
The shortcomings that the purpose of the present invention is for the above-mentioned prior art, there is provided a kind of simple in structure, manufacture is easy, leakproofness
It is good, use flange hole fast plugging device simple to operate.
The present invention is made of fixed disk 1, casing 2, rubber seal 3, pressure ram 4, pressure ram fixing nut 5.
Be sealedly and fixedly connected casing 2 on 1 centre bore of fixed disk；
Pressure ram 4 is T-shaped cylindrical bar, and external screw thread 40 is provided with the upper end of pressure ram 4；
Rubber seal 3 is set on pressure ram 4, and the upper end of pressure ram 4 is pierced by upper end and the pressure ram fixing nut of fixed disk 1
5 coordinate, and pressure ram 4 is fixedly connected on fixed disk 1；
The flange bolt connecting hole A0 on vessel flange A is corresponded on fixed disk 1 and at least offers a pair of of reducing slot bolt perforation
12, the outside diameter in the reducing slot bolt hole 12 is more than vessel flange A connection nuts or the diameter of nut A2, reducing slot bolt
The end diameter in hole 12 is slightly larger than vessel flange A connection shank of bolt A3 diameters；
Casing 2 of the present invention, rubber seal 3,4 lower end head 41 of T-shaped pressure ram outside diameter and pressure vessel on flange hole A1
Internal diameter corresponds to, and casing 2, rubber seal 3, T-shaped pressure ram 4 are inserted into flange hole A1 by when use, the reducing groove on fixed disk 1
Connection bolt on 12 companion flange A of bolt penetration hole, after nut A2 passes through the big end of the reducing slot bolt perforation 12 on fixed disk 1
Fixed disk 1 is rotated, the small end of the reducing slot bolt perforation 12 on fixed disk 1 is coordinated with the connection shank of bolt A3 on flange A, makes
Fixed disk 1 is connected with flange A by being connected shank of bolt A3 and nut A2 snap fits, then suitably screws pressure ram fixing nut
5, pressure ram 4 coordinates with casing 2 makes rubber seal 3 be extruded and flange hole A1 sealing cooperations.With in container during water pressure generation
Hydraulic pressure rise pressure ram 4 becomes larger the extruding force of rubber seal 3, and the be squeezed axial compression power of bar 4 of rubber seal 3 adds
By force, the sealing effect of the effect flange hole of rubber seal 3 A1 further improves, and ensures sealing effect.
The configuration of the present invention is simple, manufacture is easy, good airproof performance, and use is simple to operate.
Conveniently pressure testing shell flange A can be sealed by this device, eliminate time-consuming and laborious screw
The step of each flanged joint nut, avoid flange respectively connect bolt screw power difference when there is a phenomenon where leaking, and
Seal and pressure bearing ability is high, more than 20MPa.

Fig. 2 is structure of the present invention and practical view.
Fig. 3 is structure of the present invention and practical state schematic perspective view.
Embodiment
The present invention is made of fixed disk 1, casing 2, rubber seal 3, pressure ram 4, crowded bar fixing nut 5.
Be sealedly and fixedly connected casing 2 on 1 centre bore of fixed disk, casing 2 and fixed disk 1 be it is integral or
Welded seal fixed connecting sleeve 2 on the centre bore opened up on fixed disk 1, pressure ram 4 is T-shaped cylindrical bar, in the upper of pressure ram 4
End is provided with external screw thread 40, i.e. pressure ram 4 can be socket cap screw rod.
Rubber seal 3 is set on pressure ram 4, and the upper end of pressure ram 4 is pierced by the upper end of fixed disk 1, or extruding
The upper end of bar 4 is pierced by the upper end of casing 2 and pressure ram fixing nut 5 coordinates, and pressure ram 4 is fixedly connected on fixed disk 1.
The bolt connecting hole A0 on vessel flange A is corresponded on fixed disk 1 and at least offers a pair of of reducing slot bolt perforation
12, the outside diameter in the reducing slot bolt hole 12 is more than vessel flange A connection nuts or the diameter of nut A2, reducing slot bolt
The end diameter in hole 12 is slightly larger than vessel flange A connection shank of bolt A3 diameters, that is, is formed and matched somebody with somebody with the connection nuts card on flange A
Close, nuts makes the reducing on fixed disk 1 through rotation fixed disk 1 after the big end of the reducing slot bolt perforation 12 on fixed disk 1
The small end of slot bolt perforation 12 coordinates with the connection shank of bolt A3 on flange A, makes fixed disk 1 with flange A by being connected bolt card
Dress is connected.
Casing 2 of the present invention, rubber seal 3,4 lower end head 41 of T-shaped pressure ram outside diameter and pressure vessel on flange
Hole A1 internal diameters correspond to, that is, are slidably matched.
