Abstract
The utility model discloses a sealing structure of a diaphragm-type oil storage cabinet. The sealing structure comprises an upper flange installed at the bottom of an upper cabinet, a lower flange installed at the top of a lower cabinet and a diaphragm arranged between the upper flange and the lower flange; an upper tightly-pressing flange and an upper sealing component of the diaphragm are symmetrical to each other up and down; a lower tightly-pressing flange and a lower sealing component of the diaphragm are symmetrical to each other up and down; at least two pairs of protruding parts which are symmetrical and extend out are arranged at the tops and the bottoms of both the upper sealing component and the lower sealing component; and upper limiting strips and lower limiting strips are respectively arranged on two sides of both the upper sealing component and the lower sealing component. Local return spaces of the upper sealing component and the lower sealing component are relatively large and no relative deviation exists between the upper sealing component and the lower sealing component.
Description
Technical field
The utility model relates to the hermetically-sealed construction of diaphragm type storage oil cabinet
Background technology
The hermetically-sealed construction of existing diaphragm type storage oil cabinet, last seal, the end face of lower seal and bottom surface are the plane, because the direction of principal axis of oil conservator is longer, upper flange, the lower flange welded and installed can deform later on cabinet, upper flange and last seal like this, the faying face of lower flange and lower seal can form uneven gap, cause seal, inhomogeneous easy generation deformation of the compression stress that lower seal is born or relativity shift, and last seal, the local backhaul space of lower seal is less, easily following the string in the seal part can't resilience, sealing effectiveness is relatively poor, and oil seepage phenomena takes place oil conservator easily
Summary of the invention
The purpose of this utility model provides the big sealing effectiveness in a kind of backhaul space hermetically-sealed construction of diaphragm type storage oil cabinet preferably.
For achieving the above object, the technical solution adopted in the utility model is: a kind of hermetically-sealed construction of diaphragm type storage oil cabinet, described oil conservator comprises cabinet and lower cabinet body, described hermetically-sealed construction comprises and being oppositely arranged, be installed in the described upper flange and the lower flange that is installed in described lower cabinet body top of going up bottom of cabinet bulk, be arranged on be used between described upper flange and the described lower flange to separate described on the barrier film of cabinet and described lower cabinet body, push against the last seal that is used to support described upper flange of described upper flange and described barrier film, push against the lower seal that is used to support described lower flange of described lower flange and described barrier film, be adjacent to and be arranged on the described upper limit bar that the seal both sides are used to limit the position of going up, be adjacent to and be arranged on the lower limit bar that described lower seal both sides are used to limit the position, the described seal of going up, described lower seal aligns setting and end face and bottom surface up and down and has laterally zygomorphic outward extending at least two pairs of projectioies.
Preferably, described both sides of going up seal, described lower seal make progress respectively and extend to form two pairs of projectioies downwards.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: outward extending at least two pairs of projectioies that symmetry is set in last seal, lower seal end face and bottom surface, be provided for limiting upper limit bar, the lower limit bar of position respectively in last seal, lower seal side, go up seal like this, the lower seal reset capability is better, when being compressed power local backhaul space big and when being subjected to uneven compression stress relative position can not be offset, sealing effectiveness is better, and oil conservator is difficult for taking place oil seepage phenomena.
Description of drawings
Embodiment
Further set forth structure of the present utility model below in conjunction with accompanying drawing.
Referring to shown in Figure 1, diaphragm type storage oil cabinet comprises the lower cabinet body 8 of splendid attire transformer oil, link to each other with the external world and to play the respiratory cabinet 7 of going up, last cabinet 7, barrier film 3 between the lower cabinet body 8 makes transformer oil and air separation, install flange 1 in last cabinet 7 bottoms, lower flange 2 is installed at lower cabinet body 8 tops, because diaphragm type storage oil cabinet direction of principal axis distance is longer, so after installing, upper flange 1 can deform with lower flange 2, between upper flange 1 and barrier film 3, seal 5 is set, the end face of last seal 5, the bottom surface makes progress respectively, extend to form at least two pairs of projectioies that push against upper flange 1 and barrier film 3 downwards, between barrier film 3 and lower flange 2, lower seal 4 is set, the end face of lower seal 4, the bottom surface makes progress respectively, extend to form at least two pairs of projectioies that push against barrier film 3 and lower flange 2 downwards, lower seal 4, the lower flange 2 after last seal 5 is out of shape respectively and the compression of upper flange 1, the existence of projection can change lower seal 4, the compression ratio of last seal 5, make lower seal 4, effective seal clearance of last seal 5 is apart from increasing, be that local backhaul space is strengthened, lower seal 4, the ability that resets after last seal 5 is compressed is better, being subjected to after the bigger uneven compression stress not can can't resilience because of following the string, for avoiding seepage oil, the lower seal 4 of barrier film about in the of 3, last seal 5 must align, be adjacent to lower seal 4, last seal 5 both sides are provided with lower limit bar 6 respectively, upper limit bar 9, like this after being subjected to uneven compression stress, lower seal 4, relativity shift can not take place in last seal 5, and the utility model has prevented that effectively the oil seepage phenomena of diaphragm type storage oil cabinet or extraneous water from entering the phenomenon in the transformer oil
Claims (2)
1. the hermetically-sealed construction of a diaphragm type storage oil cabinet, described oil conservator comprises cabinet and lower cabinet body, it is characterized in that: described hermetically-sealed construction comprises the described upper flange and the lower flange that is installed in described lower cabinet body top of going up bottom of cabinet bulk that be installed in that is oppositely arranged, be arranged on be used between described upper flange and the described lower flange to separate described on the barrier film of cabinet and described lower cabinet body, push against the last seal that is used to support described upper flange of described upper flange and described barrier film, push against the lower seal that is used to support described lower flange of described lower flange and described barrier film, be adjacent to and be arranged on the described upper limit bar that the seal both sides are used to limit the position of going up, be adjacent to and be arranged on the lower limit bar that described lower seal both sides are used to limit the position, the described seal of going up, described lower seal aligns setting and end face and bottom surface up and down and has laterally zygomorphic outward extending at least two pairs of projectioies.
2. the hermetically-sealed construction of diaphragm type storage oil cabinet according to claim 1 is characterized in that: described both sides of going up seal, described lower seal respectively upwards and extend to form two pairs of projectioies downwards.
