Abstract
The present invention relates to a sulfur hexafluoride density relay and a density table C-shaped pipe. The pipe comprises a C-shaped pipe body, a pedestal and an end base, the pedestal and the end base are respectively connected with two ends of the C-shaped pipe body, and tin layers area arranged at the outer surfaces of the C-shaped pipe body, the pedestal and the end base. The making technology comprises the following steps: (1) performing pickling of the surfaces of the C-shaped pipe body, the pedestal and the end base, and removing the oxide and the impurity of the surface of the brass; (2) disposing the C-shaped pipe body, the pedestal and the end base into the dissolved tin liquor, and plating the tin layers on the surfaces of the C-shaped pipe body, the pedestal and the end base; and (3) connecting the pedestal and the end base with the two ends of the C-shaped pipe body through soldering. When the C-shaped pipe body is soldered with the pedestal and the end base, because there is a layer of tinning at the surface of the C-shaped pipe body, the pseudo soldering condition can not generate at soldering, and the efficiency and the reliability of the soldering are greatly improved.
Description
Technical field
The present invention relates to a kind of sulfur hexafluoride density relay, particularly relate to a kind of sulfur hexafluoride density relay and close
The C-shaped pipes of degree table and processing technology.
Background technology
Sulfur hexafluoride density relay the most on the market and density meter, be primarily used to detect sulfur hexafluoride electrical equipment
Internal sulfur hexafluoride density, main purpose is contemplated to prevent its internal sulfur hexafluoride leakage, thus causes sulfur hexafluoride electricity
Gas equipment fault, therefore the density performance of this product itself is as key index.
All use C-shaped pipes inside it as pressure-sensitive components and parts, rotated by the deformation band motivation core of C-shaped pipes, then lead to
Cross the pointer being arranged on movement, indicate corresponding reading and drive switch to reach the effect of display and relay.Have at present
Pedestal and end seat that much pyrite materials of C-shaped pipes employing, and C-shaped pipes connect also are employing pyrite, the therefore welderings between them
Connect and typically all use soldering, because brass surfaces easily aoxidizes, have layer oxide film, so there will be rosin joint when soldering,
Easily gas leakage.
Summary of the invention
The present invention is contemplated to solve the problems referred to above, overcomes sulfur hexafluoride density relay and density meter institute in prior art
The problem existed, the present invention provides a kind of sulfur hexafluoride density relay and the C-shaped pipes of density meter and processing technology to meet need
Ask.
To achieve these goals, technical scheme is as follows:
A kind of sulfur hexafluoride density relay and the C-shaped pipes of density meter, including C-shaped pipes body, pedestal and end seat, described pedestal and
End seat is connected to the two ends of C-shaped pipes body, it is characterised in that the outer surface of described C-shaped pipes body, pedestal and end seat is all provided with
It is equipped with tin layers.
The processing technology of the C-shaped pipes of a kind of sulfur hexafluoride density relay and density meter, it is characterised in that include following step
Rapid:
(1) surface to C-shaped pipes body, pedestal and end seat carries out pickling, removes oxide layer and the impurity of brass surfaces；
(2) again C-shaped pipes body, pedestal and end seat are put in the tin liquor dissolved, on C-shaped pipes body, pedestal and the surface of end seat
Plate tin layers；
(3) pedestal and end seat are connected by soldering with the two ends of C-shaped pipes body.
The invention has the beneficial effects as follows: when C-shaped pipes body welds with pedestal and end seat, because there is one layer of plating on its surface
Stannum, does not haves rosin joint situation, and the efficiency welded and reliability is greatly improved during welding.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below knot
Conjunction is specifically illustrating, and the present invention is expanded on further.
Referring to Fig. 1, a kind of sulfur hexafluoride density relay and the C-shaped pipes of density meter, including C-shaped pipes body 100, pedestal
200 are connected to the two ends of C-shaped pipes body 100, C-shaped pipes body 100, pedestal with end seat 300, pedestal 200 and end seat 300
200 are provided with tin layers with the outer surface holding seat 300.
The processing technology of the C-shaped pipes of a kind of sulfur hexafluoride density relay and density meter, comprises the following steps:
(1) surface of C-shaped pipes body 100, pedestal 200 and end seat 300 is carried out pickling, remove the oxide layer of brass surfaces and miscellaneous
Matter；
(2) again C-shaped pipes body 100, pedestal 200 and end seat 300 are put in the tin liquor dissolved, at C-shaped pipes body 100, pedestal
200 and end seat 300 plated surface on tin layers；
(3) pedestal 200 and end seat 300 are connected by soldering with the two ends of C-shaped pipes body 100.
The invention has the beneficial effects as follows: when C-shaped pipes body 100 welds with pedestal 200 and end seat 300, because its surface
Have one layer tin plating, do not have rosin joint situation during welding, and the efficiency welded and reliability be greatly improved.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.The technology of the industry
Personnel, it should be appreciated that the present invention is not restricted to the described embodiments, simply illustrating this described in above-described embodiment and description
The principle of invention, the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these become
Change and improvement both falls within scope of the claimed invention.Claimed scope by appending claims and
Equivalent defines.
