Abstract
A stemming leather cup for the oil gas pipeline is provided with a circular plate leather cup bottom on which the axial mounting holes are uniformly distributed along the circle and the external circle of the circular plate leather cup bottom is connected with an axial round-table cylindrical leather cup wall. The external edge of the round-table cylindrical leather cup wall is a sealed lip orifice, while the circular plate leather cup bottom is a cotton cloth framework rubber plate that is compounded by the cotton cloth sheets and rubber sheets in turn, and the leather cup wall is compounded by the rubber ring whose rigidity of the three layers is gradually reduced along the axial direction. Among the rubber rings with three layers of different rigidity, the rigidity of the rubber ring that is connected with the external circle of the circular plate leather cup bottom is largest. When in use, a strengthening plate is arranged on the circular plate leather cup bottom through the mounting holes and the stemming leather cup for the oil gas pipeline that is connected with a strengthening plate is positioned in the pipeline which needs the stemming by the stemming device. The high voltage is laterally faced at the leather cup of the stemming leather cup for the oil gas pipeline, while the high-voltage oil gas makes the sealed lip orifice with the smallest rigidity clung to the inner wall of the pipeline so as to carry out the stemming. The utility model has the advantages of simple structure, convenient use, large intensity and reliable seal.
Description
Technical field
The utility model relates to a kind of when maintenance oil, letter shoot road, the blocking cup ring of oil/gas transfer pipeline of being used by the maintenance pipe ends of the local corrupted of shutoff.
Background technique
Oil, letter shoot road are in use, some of pipeline is local because local corrupted takes place for mechanical deterioration or corrosion meeting, pipeline to local corrupted will repair or replace, in maintenance or when changing the pipeline of local corrupted in order not stop the conveying of oil, gas, will be at the pipe ends connecting branch line of local corrupted, and in the pipe ends pipe of local corrupted, carry out shutoff, allow oil, gas flow through from by-pass line without the pipeline of local corrupted, the pipeline to local corrupted repairs or replaces again.In order to carry out shutoff in the pipe ends pipe to local corrupted, in the prior art, a kind of liquid-transport pipe-line freeze plugging equipment is disclosed among the Chinese patent literature CN 1044327A, this shutoff equipment is arranged on by the refrigerating chamber outside the blocking pipe and can adds the gate valve refrigerant inner chamber, that the flashboard external diameter is littler than the internal diameter of the pipeline of institute shutoff in by the pipeline of shutoff, during blocking pipe, in refrigerating chamber and gate valve, charge into refrigerant, make pipeline by simultaneously freezing inside and outside the pipeline of the position of shutoff, pipe plugging is lived.This pipe plugging device structure complexity, method for blocking trouble and can only the shutoff liquid-transport pipe-line can not be used for the shutoff gas pipeline.In order to be used for the shutoff liquid-transport pipe-line, can be used for the shutoff gas pipeline again, a kind of inflation shutoff equipment is disclosed among the Chinese patent literature CN 2099236U, the seal for pipe joints aerated capsule, the seal for pipe joints aerated capsule has capsules body, one end of capsules body has inlet hole, sulfuration is connected with the metal core print on the inlet hole, the outside of metal core print is connected with metal joint by screw thread, during blocking pipe, road sealing aerated capsule is placed on pipeline by in the pipeline of the position of shutoff, in capsules body, inflates from metal joint with blocking device, match with baffle plate, pipeline is implemented shutoff.This pipe plugging equipment is air bag, and intensity is little, and sealing is not very reliable.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, proposes that a kind of device structure is simple, easy to use, the reliable sealing blocking cup ring of oil/gas transfer pipeline.
The utility model is realized with the following method.
Blocking cup ring of oil/gas transfer pipeline has at the bottom of the circular plate type leather cup, external diameter at the bottom of the circular plate type leather cup matches with the internal diameter of pipe-line, be uniformly distributed with axial mounting hole at the bottom of the circular plate type leather cup along the circumference, excircle at the bottom of the circular plate type leather cup is connected with axial round platform tubular leather cup wall, the outer of round platform tubular leather cup wall is a seal lip, be the cotton skeleton rubber plate that is composited successively by cotton sheet and sheet rubber at the bottom of the circular plate type leather cup, round platform tubular leather cup wall from inside to outside by vertically interior, in, the rubber ring that reduces successively of outer three layers of hardness is composited.
During use, on at the bottom of the circular plate type leather cup, connect stiffening plate by mounting hole, with blocking device the blocking cup ring of oil/gas transfer pipeline that is connected with stiffening plate being placed on pipeline again wants in the pipeline of block-up position, the high pressure side is facing in the leather cup of blocking cup ring of oil/gas transfer pipeline, high-pressure oil gas makes seal lip be close to inner-walls of duct, and pipeline is implemented shutoff.
The utility model is simple, easy to use, intensity is bigger, sealing is reliable, particularly round platform tubular leather cup wall from inside to outside by vertically interior, in, the rubber ring that reduces successively of outer three layers of hardness is composited, internal layer rubber ring hardness is big, make rigidity height of the present utility model, mechanical strength is big, during sealing in being used for oil and gas pipes, because the out of roundness of oil and gas pipes inner circumference is bigger, the weld bond that projection is arranged for the ratio-frequency welded tube inner tube wall, outer layer rubber ring hardness is little, and the inner wall shape that can make seal lip adapt to the oil gas pipe is adjacent to inwall, good seal performance.
Below in conjunction with accompanying drawing, the utility model is further described.
Description of drawings
Fig. 1 is that the master of blocking cup ring of oil/gas transfer pipeline looks schematic representation;
Fig. 2 is the A-A generalized section of Fig. 1;
Fig. 3 is the blocking cup ring of oil/gas transfer pipeline A-A generalized section that the excircle at the bottom of the circular plate type leather cup has the sealing pair lip.
Embodiment
Fig. 1, among Fig. 2, blocking cup ring of oil/gas transfer pipeline has at the bottom of the circular plate type leather cup 1, external diameter at the bottom of the circular plate type leather cup matches with the internal diameter of pipe-line, be uniformly distributed with axial mounting hole 2 at the bottom of the circular plate type leather cup along the circumference, excircle at the bottom of the circular plate type leather cup is connected with axial round platform tubular leather cup wall 3, the outer of round platform tubular leather cup wall is a seal lip 4, it at the bottom of the circular plate type leather cup cotton skeleton rubber plate that is composited successively by cotton sheet 5 and sheet rubber 6, round platform tubular leather cup wall is from inside to outside by in vertically, in, the rubber ring 7 that outer three layers of hardness reduce successively, 8,9 are composited, in, in, the percentage of outer three layers of rubber ring axial length in round platform tubular leather cup wall axial length is respectively: 25%～35%, 40%～50%, 20%～30%, in, in, the shore a hardness of outer three layers of rubber ring is respectively: 66 °～70 °, 56 °～60 °, 45 °～48 °.
