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 the body section perforate.

Background technique

As shown in Figure 1, 2, all the time, in the close pressure process of having a try of the other pipe of the boats and ships side of a ship, all be to 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 with wind again after the pressure testing and the welding position and carry out the work such as touch-up paint of polishing, efficient 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 and seals, but sealing effect is unsatisfactory, and can not repeatedly utilize after the stopper dismounting, cost is higher.

Summary of the invention

The objective of the invention is to overcome have in the present pipe sealing process that sealing effect is unsatisfactory, waste sealing apparatus and the higher defective of cost.

For reaching above-mentioned purpose, the invention provides a kind of pipe sealing device, comprise rubber tube and the cone guide rod that cooperates with it, the cone guide rod comprises the cone that is arranged on the one end and the screw rod that is arranged on its other end, and the small end head that this screw rod and the diameter of cone are less is connected; Be provided with the nut that is mated on the described screw rod; 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.

Be provided with a coning sleeve of fitting with this inner chamber and cone between above-mentioned inner chamber and the cone.

Be provided with a plurality of breaches that extend to the little end of diameter from the large end of its diameter on the above-mentioned coning sleeve.

Above-mentioned a plurality of breaches edge circumferentially is evenly arranged, and does not extend to the little end of described diameter, thereby makes described coning sleeve be half-open breach shape.

Above-mentioned cone is provided with a cavity that extends vertically.

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

Also be arranged with a pad on the above-mentioned screw rod, its external diameter is greater than the minimum diameter of described inner chamber.

The invention has the beneficial effects as follows: simple in structure, easy operating, sealing effect, repeatedly Reusability has been saved the man power and material.

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

Embodiment

For be overcome have in the present pipe sealing process that sealing effect is unsatisfactory, waste sealing apparatus and the higher defective of cost, present embodiment provides the device of the pipe sealing shown in a kind of Fig. 3,4, comprise rubber tube shown in Figure 33 and the cone guide rod 5 shown in Figure 4 that cooperates with it, as seen from Figure 4, cone guide rod 5 comprises the cone 6 that is arranged on one end (illustrated right-hand member) and is arranged on the screw rod 7 of its other end (illustrated left end), and the small end head that this screw rod 7 and the diameter of cone 6 are less is connected; Be provided with the nut 9 that is mated on the screw rod 7; Inner chamber 8 shapes of rubber tube 3 are 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.Be provided with a coning sleeve 4 of fitting with this inner chamber 8 and cone 6 between inner chamber 8 and the cone 6.

Referring to Fig. 5,6, be provided with a plurality of breaches 10 that extend to the little end of diameter from the large end of its diameter on the coning sleeve 4, these a plurality of breaches 10 edges circumferentially are evenly arranged, and do not extend to the little end of diameter, thereby make coning sleeve 4 be half-open breach shape.

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

Fig. 7 is the schematic representation that the pipe sealing device that utilizes present embodiment to provide seals pipe, the sealed pipe period of the day from 11 p.m. to 1 a.m, only the sealing device need to be inserted certain depth in the pipe port, sheathed its external diameter of pad 12(is greater than the external diameter of nut 9 on the screw rod 7 of cone guide rod 5), it is placed between pipe port and the nut 9, then screw nut 9, the high-elastic rubber tube 9 of centrum 6 extruding of cone guide rod 5 expands to tube wall at this moment, thereby reaches the effect of sealing.During dismounting, only need to unclamp nut 9, centrum 6 absent-mindedness of centrum guide rod 5, high-elastic rubber tube 3 is returned to normal state, no longer to the tube wall pinch, thereby can disassemble easily.This device is Reusability repeatedly, and simple to operate, has saved the man power and material.

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