Abstract
The utility model discloses an oil-filled terminal pressure relief type sealing plate, which comprises a sealing plate body, a through hole bolt, a pressure relief spring and a sealing gasket; the sealing plate body is provided with a pressure relief hole; the sealing gasket seals the pressure relief hole through the pressure relief spring and the through hole bolt. The utility model discloses can the pressure release can seal again, guarantee terminal safe operation.
Description
Technical Field
The utility model relates to an oil charge terminal closing plate specifically sets up an oil charge terminal pressure release formula closing plate.
Background
The oil-filled terminal sealing plate is used at the top of an oil-filled cable terminal product and plays a role in terminal sealing. The sealing plate used in the industry has two kinds, one is free of pressure relief and the other is externally arranged. The sealing plate without pressure relief has the defects that the oil-filled terminal generates heat during operation to cause thermal expansion, and at the moment, if the pressure cannot be released, the terminal can be subjected to operation failure or even terminal explosion. The external pressure relief type is that the pressure relief valve is arranged on the sealing plate, and the bulge is higher, so that the sealing plate is easy to damage during transportation or installation and cannot play a role in sealing.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide an oil charge terminal pressure release formula closing plate, when playing the terminal sealing effect, can release internal pressure.
In order to solve the technical problem, the utility model discloses take following technical scheme: an oil-filled terminal pressure relief type sealing plate comprises a sealing plate body, a through hole bolt, a pressure relief spring and a sealing gasket; the sealing plate body is provided with a pressure relief hole; the sealing gasket seals the pressure relief hole through the pressure relief spring and the through hole bolt.
Further, a cavity is arranged above the pressure relief hole of the sealing plate body; the cavity is communicated with the pressure relief hole; the sealing gasket is arranged at the bottom of the cavity; the top of the cavity is provided with a through hole bolt; a pressure relief spring is also arranged in the cavity; the pressure relief spring is located between the through hole bolt and the sealing gasket.
Further, the pressure relief hole and the cavity are coaxially arranged, and the diameter of the cavity is larger than that of the pressure relief hole.
Further, the pressure relief spring applies pressure to the sealing gasket, and the sealing gasket seals the pressure relief hole.
Furthermore, the upper part of the cavity is provided with internal threads, and the through hole is in bolted connection with the cavity.
Further, the pressure applied to the sealing gasket by the pressure relief spring is adjusted through the adjusting through hole bolt.
The utility model has the advantages that: the utility model discloses can the pressure release can seal again, guarantee terminal safe operation.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments described in the present invention, and it is obvious for those skilled in the art to obtain other drawings without creative efforts.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solution of the present invention will be described clearly and completely through the following detailed description.
As shown in fig. 1, the oil-filled terminal pressure relief type sealing plate of the present invention comprises a sealing plate body 1, a through-hole bolt 2, a pressure relief spring 3 and a sealing gasket 4; the sealing plate body 1 is provided with a pressure relief hole 11; the sealing plate body 1 of the utility model is provided with a cavity 12 above the pressure relief hole 11; the cavity 12 is communicated with the pressure relief hole 11; the sealing gasket 4 is arranged at the bottom of the cavity 12; the upper part of the cavity 12 is provided with internal threads, and the through hole bolt 2 is screwed on the cavity 12; a pressure relief spring 3 is also arranged in the cavity; and the pressure relief spring 3 is positioned between the through hole bolt 2 and the sealing gasket 4. The pressure relief hole 11 and the cavity 12 are coaxially arranged, and the diameter of the cavity 12 is larger than that of the pressure relief hole 11. The pressure relief spring 3 applies pressure to the gasket 4, and the gasket 4 seals the pressure relief hole 11. The utility model discloses a pressure that pressure release spring 3 was applied to sealed 4 of pad is adjusted to adjusting through-hole bolt 2.
The oil-filled terminal sealing plate is used at the top of an oil-filled cable terminal product, plays a role in sealing the terminal, and the terminal can generate heat in the operation process, so that the internal pressure of the terminal is increased and expanded. After the internal pressure of the oil filling terminal is increased, the internal pressure overcomes the pressure applied to the sealing gasket by the pressure relief spring, the sealing gasket is opened through the pressure relief hole, the pressure relief spring contracts and exhausts pressure, and the pressure relief spring compresses the sealing gasket to seal the pressure relief hole after the pressure is released. The utility model discloses a through-hole bolt, spring, the three device of sealed pad make the closing plate have pressure release and sealed effect, guarantee terminal safe operation.
The above-mentioned embodiments are only described as the preferred embodiments of the present invention, and are not intended to limit the concept and scope of the present invention, and the technical content of the present invention, which is claimed by the present invention, is fully recorded in the technical claims.
