Abstract
The utility model relates to a sealing element for a connecting pipeline. The sealing element comprises a welding loose joint, a welding loose-joint nut and a double nipple, wherein the welding loose joint is fixed with the double nipple by the welding loose-joint nut. The utility model provides the sealing element for the connecting pipe, wherein the sealing element is obvious in sealing effect and simple in structure.
Description
Technical field
The utility model belongs to fluid pipeline conveying technology field, relates to a kind of sealing configuration, relates in particular to the connecting tube Sealing that is adopted when a kind of oil product is connected with all kinds of valves in line transportation.
Background technique
In industrial oil (like diesel oil, kerosene, gasoline, hydraulic oil and lubricated wet goods) production, transportation, use and storage process, all can use various pipelines, valve, flange etc., use 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 the pipeline adds forms such as raw meal belt, sealer, and for the stronger oil product of osmotic force, like diesel oil, its sealing effect is poor, seepage often occurs, can not satisfy usage requirement.
The model utility content
In order to solve the above-mentioned technical problem that exists in the background technique, the utility model provides a kind of significant sealing affection and connecting tube Sealing simple in structure.
The technical solution of the utility model is: the utility model provides a kind of connecting tube Sealing, and its special way is: said connecting tube Sealing comprises welding loose joint joint, welding loose joint nut and to silk; Said welding loose joint joint is through welding the loose joint nut and silk being fixed together.
Above-mentioned welding loose joint joint stretches in the welding loose joint nut; The compressing of said welding loose joint nut on welding loose joint joint and with silk is threaded.
Above-mentioned connecting tube Sealing also comprises and is arranged on welding loose joint joint and the O shape between the silk enclosed.
Above-mentioned connecting tube Sealing also comprises and being arranged on the silk and away from the combination seal packing ring of welding loose joint nut one end.
The utility model has the advantages that:
The utility model has increased the special mechanical structure Sealing of structure the delivery main with the connecting tube place that is used to be connected filter core; This mechanical structure be welding loose joint joint through silk and delivery main are linked together, be socketed with at welding loose joint joint with to the joint of silk simultaneously and weld the loose joint nut; Better for sealing effect, the utility model is provided with O type circle in welding loose joint joint and joint to silk respectively, and between to silk and delivery main in addition the combination seal packing ring seal, realize the effect of double seal.The utility model is to the sealing effect highly significant of delivery main and connecting tube, and is simple in structure, convenient follow-up purification process.
Description of drawings
Fig. 1 is the structural representation of the connecting tube Sealing that provides of the utility model;
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 utility model provides a kind of connecting tube Sealing, and this connecting tube Sealing comprises welding loose joint joint 2, welding loose joint nut 3 and to silk 5; Welding loose joint joint 2 is through 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 the welding loose joint nut 3; 3 compressings of welding loose joint nut on welding loose joint joint 2 and with silk 5 is threaded.
For the sealing effect that makes the utility model more remarkable; The connecting tube Sealing that the utility model provided also comprises and is arranged on welding loose joint joint 2 and to the circle of the O shape between the silk 54, and is arranged on the silk 5 and away from the combination seal packing ring 6 of welding loose joint nut 3 one ends.
The utility model will be connected on the delivery main through combination seal packing ring 6 silk 5 in use, and the other end is welded on the welded tube elbow 1 through the welding movable joint, so far, has accomplished the sealing between delivery main and the welded tube.
The utility model is applicable to the connection between existing various pipelines, valve, the flange.
