Abstract

The invention provides a pipe sealing device, which comprises a rubber sleeve and a cone guide rod matched with the rubber sleeve. The cone guide rod comprises a cone and a threaded rod, wherein the cone is arranged at one end of the cone guide rod, and the threaded rod is arranged at the other end of the cone guide rod; the threaded rod is connected with a smaller-diameter small end of the cone; the threaded rod is provided with a nut matched with the threaded rod; the shape of an inner cavity of the rubber sleeve is the same as the outline shape of the cone; the inner cavity and the cone are fitted together; and the outer diameter of the nut is greater than the minimum diameter of the inner cavity. The pipe sealing device is simple in structure, easy in operation and good in sealing effect and can be repeatedly used, and therefore, manpower and material resources are saved.

Description

A kind of pipe sealing device

Technical field

The invention belongs to hull frock field, particularly relate to a kind of segmentation perforate frock for body section perforate.

Background technique

As shown in Figure 1, 2, all the time, press through in journey close the having a try of the other pipe of the boats and ships side of a ship, all adopt at the other outside pipe port welding blind plate 1 of the side of a ship or in pipe, squeeze into stopper 2 to seal pipe, and then carry out the close pressure of having a try of pipe, slice off the blind plate of welding and the welding position carry out the work such as touch-up paint of polishing with wind again after pressure testing, efficiency is generally all lower.The other pipe of the side of a ship of ship deck draining pipe also adopts sometimes to be squeezed into stopper to seal, but sealing effect is unsatisfactory, and stopper can not repeatedly utilize after dismantling, cost is higher.

Summary of the invention

The object of the invention is to overcome in current pipe sealing process and there is the defect that sealing effect is unsatisfactory, waste seals apparatus and cost is higher.

For reaching above-mentioned purpose, the invention provides a kind of pipe sealing device, the cone guide rod comprising rubber tube and coordinate with it, cone guide rod comprises the cone being arranged on its one end and the screw rod being arranged on its other end, and the small end head that this screw rod is less with the diameter of cone is connected; Described screw rod is provided with the nut be mated; The cavity shape of described rubber tube is identical with the contour shape of described cone, and this inner chamber and this cone fit together; The external diameter of described nut is greater than the minimum diameter of described inner chamber.

A coning sleeve of fitting with this inner chamber and cone is provided with between above-mentioned inner chamber and cone.

Above-mentioned coning sleeve is provided with the breach that multiple one end large from its diameter extends to one end that diameter is little.

Above-mentioned multiple breach is circumferentially evenly arranged, and does not extend to the little one end of described diameter, thus makes described coning sleeve be half-open breach shape.

Above-mentioned cone is provided with a cavity extended vertically.

The shape of above-mentioned cavity is identical with the profile of cone.

Above-mentioned screw rod is also arranged with a pad, and its external diameter is greater than the minimum diameter of described inner chamber.

The invention has the beneficial effects as follows: structure is simple, be easy to operation, sealing effect, can repeatedly Reusability, save man power and material.

Below in conjunction with the drawings and the specific embodiments, the present invention is described in further detail.

Embodiment

In order to be overcome in current pipe sealing process have that sealing effect is unsatisfactory, waste sealing apparatus and the higher defect of cost, present embodiments provide the pipe sealing device shown in a kind of Fig. 3,4, the cone guide rod 5 shown in Fig. 4 comprising the rubber tube 3 shown in Fig. 3 and coordinate with it, as seen from Figure 4, cone guide rod 5 comprises the cone 6 being arranged on its one end (illustrated right-hand member) and the screw rod 7 being arranged on its other end (illustrated left end), and the small end head that this screw rod 7 is less with the diameter of cone 6 is connected; Screw rod 7 is provided with the nut 9 be mated; Inner chamber 8 shape of rubber tube 3 is identical with the contour shape of cone 6, and this inner chamber 8 fits together with this cone 6; The external diameter of nut 9 is greater than the minimum diameter of inner chamber 8.A coning sleeve 4 of fitting with this inner chamber 8 and cone 6 is provided with between inner chamber 8 and cone 6.

See Fig. 5,6, coning sleeve 4 is provided with the breach 10 that multiple one end large from its diameter extends to one end that diameter is little, the plurality of breach 10 is circumferentially evenly arranged, and does not extend to the little one end of diameter, thus makes coning sleeve 4 in half-open breach shape.

As seen from Figure 6, cone 6 is provided with a cavity extended vertically 11, and its shape is identical with the profile of cone 6, so can alleviate the weight of cone 6.

Fig. 7 is the schematic diagram that the pipe sealing device utilizing the present embodiment to provide seals pipe, the sealed pipe period of the day from 11 p.m. to 1 a.m, sealing device is only needed to insert certain depth in pipe port, on the screw rod 7 of cone guide rod 5, sheathed its external diameter of pad 12(is greater than the external diameter of nut 9), it is made to be placed between pipe port and nut 9, then tightening nut 9, now the centrum 6 of cone guide rod 5 extrudes elastomer cylinder 9 to tube wall expansion, thus reaches the effect of sealing.During dismounting, only need to unclamp nut 9, the centrum 6 of centrum guide rod 5 is relaxed, and elastomer cylinder 3 is returned to normal state, no longer causes extruding to tube wall, thus can get off by easy removal.This device can repeatedly Reusability, and simple to operate, has saved man power and material.

Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
