Abstract
The utility model discloses a kind of electric insulation threaded connector for vessel, described cap nut is connected with the outside thread of inipple by internal thread, the first end of described flat shoulder grafting extends to the inside of cap nut, described half fraction insulating sleeve is arranged on flat shoulder grafting head, described metal washer and insulation spacer are enclosed within half fraction insulating sleeve successively, described gasket seal is arranged on the inside of cap nut, and is positioned at the joint of inipple peace shoulder grafting head.Inipple of the present utility model can replace with three general characters, four-way or many flow-throughs structure, realize the connection with multichannel pipeline, the mode that inipple is connected with external pipeline simultaneously can replace with welding type, screw connected or other Placement, makes inipple be applicable to threeway, four-way or the pipeline leading to form more and connects.Flat shoulder grafting head and inipple thoroughly insulate out, and play the effect of electrical insulation, avoid the direct contact of different metal materials pipeline, make it not possess the condition that electro erosion reaction occurs.
Description
Technical field
The utility model relates to insulation threaded connector field, especially a kind of electric insulation threaded connector for vessel.
Background technique
At present, the structure of the inipple that China's industry-by-industry uses does not have the performance of electrical insulation, the pipeline that the dissimilar metal that particularly ships and some special industries use docks, when connecting with regular screw threads joint, (metallic material of different activities is simultaneously in electrolyte solution will to produce electrochemical corrosion reaction between pipeline, electrochemical corrosion reaction can be produced), the metallic conduit accelerated corrosion that electrochemical corrosion reaction can make current potential low, pipeline will be caused like this to leak in advance, simultaneously can initiation potential, the working life of pipeline also can shorten greatly.
Model utility content
For the problems referred to above, the utility model aims to provide a kind of by certain measure, makes the electric insulation threaded connector for vessel of thoroughly insulation between flat shoulder grafting head and inipple.
For realizing this technical purpose, scheme of the present utility model is:
A kind of electric insulation threaded connector for vessel, comprise inipple, cap nut, flat shoulder grafting head, half fraction insulating sleeve, metal washer, gasket seal and insulation spacer, described cap nut is connected with the outside thread of inipple by internal thread, the first end of described flat shoulder grafting extends to the inside of cap nut, described half fraction insulating sleeve is arranged on flat shoulder grafting head, described metal washer and insulation spacer are enclosed within half fraction insulating sleeve successively, described gasket seal is arranged on the inside of cap nut, and is positioned at the joint of inipple peace shoulder grafting head.
As preferably, described inipple is straight-through or many flow-throughs structure.
As preferably, the pipeline that described inipple peace shoulder grafting head is all threaded connection or welding manner connects with it separately connects.
As preferably, one end of described flat shoulder grafting head is coated with high-temperature insulating coating.
As preferably, described flat shoulder grafting head is provided with insulating sleeve, insulation spacer and metal washer parts.
Flat shoulder grafting head of the present utility model is identical or close with the material of all connected metal tubes of inipple, the material of cap nut is close with the material of inipple, the strength of materials is higher than inipple, flat shoulder grafting head converts arbitrarily with the material of the pipeline that the metallic material of inipple, cap nut can be connected as required, as: carbon steel, stainless steel, copper, titanium or titanium alloy etc.Inipple can replace with three general characters, four-way or many flow-throughs structure, realize the connection with multichannel pipeline, the mode that inipple is connected with external pipeline simultaneously can replace with welding type, screw connected or other Placement, thus makes inipple be applicable to threeway, four-way or the pipeline connection of leading to form more.By adopting insulation spacer, half fraction insulating sleeve, insulation coating and gasket seal, flat shoulder grafting head and inipple are thoroughly insulated out, thus serve the effect of electrical insulation, avoid the direct contact of different metal materials pipeline, make it not possess the condition that electro erosion reaction occurs.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is sectional view of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1-2, a kind of electric insulation threaded connector for vessel of the utility model embodiment, comprise inipple 1, cap nut 2, flat shoulder grafting head 3, half fraction insulating sleeve 4, metal washer 5, gasket seal 6 and insulation spacer 7, described cap nut 2 is connected by the outside thread of internal thread with inipple 1, described flat shoulder grafting head 3 one end extends to the inside of cap nut 2, described half fraction insulating sleeve 4 is arranged on flat shoulder grafting head 3, described metal washer 5 and insulation spacer 7 are enclosed within half fraction insulating sleeve 4 successively, described gasket seal 6 is arranged on the inside of cap nut 2, and be positioned at the joint of the peaceful shoulder grafting head 3 of inipple 1.
As preferably, described inipple 1 is straight-through or many flow-throughs structure.
As preferably, the pipeline that the peaceful shoulder grafting head 3 of described inipple 1 is all threaded connection or welding manner connects with it separately connects.
As preferably, one end of described flat shoulder grafting head 3 is coated with high-temperature insulating coating.
As preferably, described flat shoulder grafting head 3 is provided with insulating sleeve, insulation spacer and metal washer parts.
Flat shoulder grafting head 3 of the present utility model is identical or close with the material of all connected metal tubes of inipple 1, the material of cap nut 2 is close with the material of inipple 1, the strength of materials is higher than inipple, flat shoulder grafting head 3 converts arbitrarily with the material of the pipeline that the metallic material of inipple 1, cap nut 2 can be connected as required, as: carbon steel, stainless steel, copper, titanium or titanium alloy etc.Inipple 1 can replace with three general characters, four-way or many flow-throughs structure, realize the connection with multichannel pipeline, the mode that inipple 2 is connected with external pipeline simultaneously can replace with welding type, screw connected or other Placement, thus makes inipple 1 be applicable to threeway, four-way or the pipeline connection of leading to form more.By adopting insulation spacer 7, half fraction insulating sleeve 4, insulation coating and gasket seal 6, flat shoulder grafting head 3 and inipple 1 are thoroughly insulated open, thus serve the effect of electrical insulation, avoid the direct contact of different metal materials pipeline, make it not possess the condition that electro erosion reaction occurs.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
