Abstract
The invention relates to a sealing part of a connecting pipe, which comprises a welding loose joint connector, a welding loose joint nut and a double nipple. The welding loose joint connector is fixed with the double nipple via the welding loose joint nut. The sealing part of the connecting pipe is remarkable in sealing effect and simple in structure.
Description
Technical field
The invention belongs to fluid pipeline conveying technology field, relate to a kind of sealing configuration, relate in particular to the sealing part of connecting pipe adopting when a kind of oil product is connected with all kinds of valves in pipeline is carried.
Background technique
In industrial oil (as diesel oil, kerosene, gasoline, hydraulic oil and lubricated wet goods) production, transportation, use and storage process, capital uses various pipelines, valve, flange etc., uses the connection of memory device and the control of flow direction to realize liquid.Being connected and sealing the pipe thread that adopt more between valve and pipeline adds the form such as raw meal belt, sealer, and for the stronger oil product of osmotic force, as diesel oil, its sealing effect is poor, often occurs seepage, can not meet usage requirement.
Summary of the invention
In order to solve the above-mentioned technical problem existing in background technique, the invention provides a kind of significant sealing affection and sealing part of connecting pipe simple in structure.
Technical solution of the present invention is: the invention provides a kind of sealing part of connecting pipe, its special way is: described sealing part of connecting pipe comprises welding loose joint joint, welding loose joint nut and to silk; Described welding loose joint joint is by welding loose joint nut and silk being fixed together.
Above-mentioned welding loose joint joint stretches in welding loose joint nut; Described welding loose joint nut compressing is being welded on loose joint joint and silk is being threaded.
Above-mentioned sealing part of connecting pipe also comprises and is arranged on welding loose joint joint and to the O shape circle between silk.
Above-mentioned sealing part of connecting pipe also comprise be arranged on on silk and away from welding loose joint nut one end combination seal packing ring.
Advantage of the present invention is:
The present invention has increased the special mechanical structure Sealing of structure with the connecting tube place for being connected filter core delivery main, this mechanical structure is to weld loose joint joint by silk and delivery main are linked together, and is socketed with welding loose joint nut at welding loose joint joint with to the joint of silk simultaneously; For sealing effect better, the present invention respectively welding loose joint joint with the joint of silk is provided with to O type circle, and between to silk and delivery main in addition combination seal packing ring seal, realize the effect of double seal.The sealing effect highly significant of the present invention to delivery main and connecting tube, simple in structure, facilitate follow-up purification process.
Accompanying drawing explanation
Fig. 1 is the structural representation of sealing part of connecting pipe provided by the present invention;
Wherein:
1-welded tube elbow, 2-welding loose joint joint, 3-welding loose joint nut, 4-O shape circle, 5-are to silk, 6-combination seal packing ring.
Embodiment
Referring to Fig. 1, the invention provides a kind of sealing part of connecting pipe, this sealing part of connecting pipe comprises welding loose joint joint 2, welding loose joint nut 3 and to silk 5; Welding loose joint joint 2 is by welding loose joint nut 3 and silk 5 being fixed together, and this means of fixation can be that welding loose joint joint 2 stretches in welding loose joint nut 3; Welding loose joint nut 3 oppress on welding loose joint joint 2 and with silk 5 is threaded.
In order to make sealing effect of the present invention more remarkable, sealing part of connecting pipe provided by the present invention also comprises and is arranged on welding loose joint joint 2 and to the O shape circle 4 between silk 5, and is arranged on silk 5 and away from the combination seal packing ring 6 of welding loose joint nut 3 one end.
The present invention in use, will be connected to delivery main by combination seal packing ring 6 to silk 5 upper, and the other end is welded on welded tube elbow 1 by welding movable joint, so far, has completed the sealing between delivery main and welded tube.
The present invention is applicable to the connection between existing various pipelines, valve, flange.
