Abstract
The utility model is related to the C-shaped pipes of a kind of sulfur hexafluoride density relay and density meter, and including C-shaped pipes body, pedestal and end seat, pedestal and end seat are connected to the two ends of C-shaped pipes body, and the outer surface of C-shaped pipes body, pedestal and end seat is provided with tin layers.The beneficial effects of the utility model are：When C-shaped pipes body and pedestal and end seat are welded because its surface have one layer tin plating, be not in rosin joint situation during welding, and the efficiency welded and reliability greatly improved.
Description
Technical field
The utility model is related to a kind of sulfur hexafluoride density relay, more particularly to a kind of sulfur hexafluoride density relay
C-shaped pipes with density meter.
Background technology
Sulfur hexafluoride density relay on the market and density meter, are primarily used to detect sulfur hexafluoride electrical equipment at present
Internal sulfur hexafluoride density, main purpose be exactly in order to prevent its internal sulfur hexafluoride leakage, so as to cause sulfur hexafluoride electricity
Gas equipment fault, therefore the product density performance of itself is used as key index.
C-shaped pipes are all used inside which as pressure-sensitive components and parts, rotated by the deformation band motivation core of C-shaped pipes, then lead to
The pointer that crosses on movement, indicates corresponding reading and drives switch to reach the effect of display and relay.Have at present
The pedestal of much brass materials of C-shaped pipes employing, and C-shaped pipes connection and end seat are also to adopt brass, the therefore weldering between them
Connect and typically soldering all adopted, because brass surfaces are easily aoxidized, layer oxide film is had, so rosin joint occurs in soldering,
Easily gas leakage.
Utility model content
The utility model is exactly to solve the above problems, and overcomes sulfur hexafluoride density relay and density in prior art
The problems of table, the utility model provide the C-shaped pipes of a kind of sulfur hexafluoride density relay and density meter to meet demand.
To achieve these goals, the technical solution of the utility model 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, the base
Seat and end seat are connected to the two ends of C-shaped pipes body, it is characterised in that the outer surface of the C-shaped pipes body, pedestal and end seat
It is provided with tin layers.
The manufacture craft of the C-shaped pipes of a kind of sulfur hexafluoride density relay and density meter, it is characterised in that including following step
Suddenly：
(1) pickling is carried out to the surface of C-shaped pipes body, pedestal and end seat, 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 that dissolves, in C-shaped pipes body, pedestal and end seat
Tin layers on plated surface；
(3) pedestal and end seat are connected by soldering with the two ends of C-shaped pipes body.
The beneficial effects of the utility model are：When C-shaped pipes body is welded with pedestal and end seat, because its surface has one layer
Tin plating, be not in rosin joint situation during welding, and the efficiency of welding and reliability are greatly improved.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Referring to Fig. 1, the C-shaped pipes of a kind of sulfur hexafluoride density relay and density meter, including C-shaped pipes body 100, pedestal
200 and end seat 300, pedestal 200 and end seat 300 are connected to the two ends of C-shaped pipes body 100, C-shaped pipes body 100, pedestal
200 and the outer surface of end seat 300 be provided with tin layers.
A kind of manufacture craft of the C-shaped pipes of sulfur hexafluoride density relay and density meter, comprises the following steps：
(1) pickling is carried out to the surface of C-shaped pipes body 100, pedestal 200 and end seat 300, removes the oxide layer of brass surfaces
And impurity；
(2) again C-shaped pipes body 100, pedestal 200 and end seat 300 are put in the tin liquor that dissolves, C-shaped pipes body 100,
Tin layers on the plated surface of pedestal 200 and end seat 300；
(3) pedestal 200 and end seat 300 are connected by soldering with the two ends of C-shaped pipes body 100.
The beneficial effects of the utility model are：When C-shaped pipes body 100 is welded with pedestal 200 and end seat 300, because its
Surface have one layer tin plating, be not in rosin joint situation during welding, and weld efficiency and reliability greatly improve.
General principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply principle of the present utility model is described, the utility model can also on the premise of without departing from the utility model spirit and scope
There are various changes and modifications, these changes and improvements are both fallen within the range of claimed the utility model.The utility model will
Protection domain is asked to be defined by appending claims and its equivalent.
