Description

A kind of drawn tube for transformator
Technical field
This utility model relates to transformer technology field, a kind of drawn tube for transformator.
Background technology
Drawn tube is a kind of novel high-tech energy-conserving product.The popularization and application of cold-drawn high-precision, to saving steel, improve processing work efficiency, save the energy.So-called cold-drawn high-precision refers to that dimension of inner and outer diameters precision (margin of tolerance) is strict, surfaces externally and internally fineness, circularity, straight degree are good, uniform wall thickness, the key technical indexes of the cold-drawn high-precision that this technology is produced has reached or part exceedes standard GB/T 8713--88 and the requirement of international standard ISO4394/I-1980 (E).
The pipeline major part used on transformator at present is obsolete techniques, waste of material is many, service life is the highest, and when being used on oil circuit, there is no that filtration, direct pipeline are input in pipeline, use on transformator causes the biggest impact, operation volume is the most inconvenient, and it is bad that conventional tube there is also antiseptic effect, the problem that service life is short.
Therefore, it is badly in need of the solution that makes new advances of research and development, solves above-mentioned technical problem, reduce cost, improve and convenient degree is installed, realize the filtration of oil circuit simultaneously, increase pipeline service life, improve Business Economic Benefit.
Utility model content
The purpose of this utility model is that provides a kind of drawn tube for transformator to solve the problems referred to above.
A kind of drawn tube for transformator, including through cold-drawn body out;A discharge hydraulic fluid port and oil-in staggered between two oil-outs it is provided with on described body;The portion of upper surface that described oil-in protrudes is provided with drainage screen;Described drainage screen is fixed by being arranged on the joint body of the part upper end that oil-in protrudes;Described joint body bottom is provided with the circular draw-in groove for snapping in the part that oil-in protrudes;Described joint body side is provided with screw-threaded coupling device, and screw-threaded coupling device passes joint body, stretches in body.
Further, described drainage screen specification is 300 mesh/inch.
Further, described joint body is provided with external screw thread, and joint body is internally provided with the female thread of 5-8cm.
Further, described inner surface of tube body is evenly arranged with the anticorrosive coat of 0.3-0.5mm.
The beneficial effects of the utility model are: this utility model simple in construction, reasonable in design, Stability Analysis of Structures, apply using effect on the transformer fine, it is possible to achieve the filtration of fluid, and easy accessibility, clean easily, there is anticorrosion, the feature of oil resistant erosion, high life.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation;
In figure: 1, body, 2, oil-out, 3, oil-in, 4, drainage screen, 5, joint body, 6, screw-threaded coupling device, 7, draw-in groove.
Detailed description of the invention
The utility model is described in further detail for embodiment in below in conjunction with the accompanying drawings, but is not intended that any restriction of the present utility model.
Referring to shown in Fig. 1, this utility model provides a kind of technical scheme: a kind of drawn tube for transformator, including through cold-drawn body 1 out;A discharge hydraulic fluid port 2 and oil-in 3 staggered between two oil-outs 2 it is provided with on described body 1;The portion of upper surface that described oil-in 3 protrudes is provided with drainage screen 4;Described drainage screen 4 is fixed by being arranged on the joint body 5 of the part upper end that oil-in 3 protrudes;Described joint body 5 bottom is provided with the circular draw-in groove 7 for snapping in the part that oil-in 3 protrudes;Described joint body 5 side is provided with screw-threaded coupling device 6, and screw-threaded coupling device 6, through joint body 5, stretches in body 1.During installation, drainage screen 4 is placed on above the part that oil-in 3 protrudes, and the portion of upper surface size that the planar dimension of drainage screen 4 protrudes more than oil-in 3, then the draw-in groove 7 card main filter screen 4 of joint body 5, drainage screen 4 is pressed in draw-in groove 7, is locked by screw-threaded coupling device 6.
As preferred version of the present utility model, described drainage screen 4 specification is 300 mesh/inch, can effectively filter fluid, and dismount, easy to clean, repeatable utilization.
As preferred version of the present utility model, described joint body 5 is provided with external screw thread, and joint body 5 is internally provided with the female thread of 5-8cm, can according to circumstances access male-pipe or riffled tube, and adaptability is higher.
As preferred version of the present utility model, described body 1 inner surface is evenly arranged with the anticorrosive coat of 0.3-0.5mm, anticorrosion, oil resistant, improves service life.
Embodiment provided above is better embodiment of the present utility model, only it is used for convenient explanation this utility model, not this utility model is made any pro forma restriction, any art has usually intellectual, if in the range of without departing from the carried technical characteristic of this utility model, utilize the Equivalent embodiments that the done local of this utility model disclosed technology content is changed or modified, and without departing from technical characteristic content of the present utility model, all still fall within the range of this utility model technical characteristic.
