Description
Technical field
The present invention relates to the attachment means technical field of pipe, more particularly to a kind of oil-filtering pipe joint of transformer.
Background technology
Unless regularly safeguarded, no matter how carefully the installation of transformer and operation, transformer oil can still be subject to dirt
Dye.The insulation characterisitic one of oil declines, and equipment fault will occur.Appropriate maintenance institute of the failure cost of equipment than transformer oil
The expense and time spent are much greater.The purpose of transformer's oil-treatment is eliminated in equipment when using, or will be in equipment
The middle oily moisture and other pollutants for using.In oil strain operating process is carried out to transformer, usually occur oil filter from
Oil storage point situation too far, and do not have enough length with oil strain pipeline, and oil strain pipeline and can not be connected to one
Rise so that oil strain process is difficult, even if oil strain pipeline reluctantly and is connected to together, also easily cause tie point poor sealing, easily
Cause the waste of oil during oil transportation.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of oil-filtering pipe joint of transformer, can be with by the joint
Easily, efficiently two oil-filter pipes are coupled together, and it is good to be tightly connected effect, does not result in transformer oil leakage, therefore
Do not influenceed by oil storage point distance, improve the speed of filtering oil for transformer work, efficiency high.
In order to solve the above technical problems, the technical solution used in the present invention is：A kind of oil-filtering pipe joint of transformer, its
It is characterised by：Including male and female, the male includes the first connecting tube, and the end of the first connection pipe outer wall is fixed with
Sealing ring, the female includes the second connecting tube, and second connecting tube is provided with two openings, on the tube wall outside the opening
It is provided with two pairs of connecting plates, two check lock levers are connected board shaft connection with a pair respectively, and one end of the check lock lever is located at described the
In the opening of two connecting tubes, the other end of check lock lever is located at the outside of second connecting tube, the second company on the right side of the opening
The inwall of adapter is provided with annular groove, and O-ring seal is fixed with the annular groove, and the internal diameter of the O-ring seal is bigger
In the external diameter of the sealing ring, when first connecting tube is inserted into second connecting tube, the sealing ring with it is described
O-ring seal directly contact simultaneously will extrude the O-ring seal, and now, the end that the check lock lever is located in the opening is relative
Protruded in the inwall of second connecting tube, and the left end face of the sealing ring is located at the second connecting tube inner end with check lock lever
Horizontal range the horizontal range of the second connecting tube inner end is located at less than its right end face and the check lock lever of the O-ring seal.
Further technical scheme is：The inwall and outer wall of first connecting tube are provided with screw thread, described first
Connecting tube is fixedly connected by the screw thread on outer wall with the oil inlet on oil filter.
Further technical scheme is：The joint is also stifled including male end, when male is not inserted into the female, institute
State that male end is stifled to be fixedly connected between first connecting tube by the screw thread on inwall, first connecting tube is sealed
Close.
Further technical scheme is：The stifled side in the male end is fixed with fixed column, and the fixed column is provided with
Through hole.
Further technical scheme is：The joint is also stifled including female end, when male is not inserted into the female, institute
State that female end is stifled to be inserted into the male, will the described second connection duct occlusion.
Further technical scheme is：The check lock lever includes vertical portion, horizontal part and rake, the vertical portion
One end be free end, the free end is located in the via, the other end of the vertical portion by the rake with it is described
One end connection of horizontal part.
Further technical scheme is：The check lock lever also includes the supporting part vertical with the horizontal part, works as male
When being in locking state with female, the supporting part is vertical with second connecting tube and directly contact.
It is using the beneficial effect produced by above-mentioned technical proposal：The joint include male and female, when need connect
When connecing two oil-filter pipes, male is fixedly connected with one end of an oil-filter pipe, female is fixed with one end of another oil-filter pipe
Connection, afterwards, rotates the check lock lever in the female, make check lock lever medial end be located at the described second connection inside pipe wall it
Outward, now, the sealing ring in male can be smoothly inserted into second connecting tube, after male insertion, outside sealing ring
Enclose the inner ring directly contact with the O-ring seal and extrude the O-ring seal, make O-ring seal that certain deformation to occur, it
After rotate the check lock lever, the medial end of check lock lever is protruded relative to the inwall of second connecting tube, now, check lock lever
Medial end can effectively prevent the male from being skidded off from female relative to the projection of the described second connection inside pipe wall.
To sum up, easily, efficiently two oil-filter pipes can be coupled together by the joint, and is tightly connected effect
It is good, do not result in transformer oil leakage, therefore do not influenceed by oil storage point distance, the speed that filtering oil for transformer works is improve,
Efficiency high.
Additionally, the check lock lever also includes the supporting part vertical with the horizontal part, when male and female are in locking shape
During state, the supporting part is vertical with second connecting tube and directly contact, can be effectively to locking position by the supporting part
Put and positioned, prevent the inaccurate locking effect for causing of the locked position of check lock lever bad.The male end is stifled can be by public affairs
Head closing, female end is stifled can be closed female, prevented when not in use, and the transformer oil outflow of residual, causes in oil-filter pipe
Pollution.
