Description
Technical field
The utility model is related to a kind of flame-proof type pressure-bearing terminations, are particularly applicable in high temperature and pressure flame-proof type shielded electric pump
Or on high temperature and pressure flame-proof type shield electric machine.
Background technology
The termination of shielded electric pump is arranged between bore of stator and terminal box, and sealing is as secondary pressure at termination
Boundary design can sustain system pressure, it is ensured that when stator can leaks, medium will not leak.Currently, high temperature is high
Pressure shielded electric pump medium is deionized water, and using area is non-explosion-proof area, and the wiring of such high temperature and pressure shielded electric pump fills
High temperature and pressure can be born by setting, but can not be used as explosion-proof type termination, and the termination of plain edition shielded electric pump is explosion-proof
Type termination, but high temperature and pressure can not be born, major oil refining enterprise such as CNOOC, petrochina carries out oil product upgrading in recent years
Transformation project, the environment for using high temperature and pressure canned motor pump are 2nd area of danger zone that possible carry explosive gas, and this requires height
Warm high-voltage shielded electrical motor, electric pump are not only able to bear high temperature and pressure that explosion-proof effect can also be played.It is external now to use pouring type
Explosion-proof form, but be not easy to disassemble and install.
Invention content
The purpose of the utility model is to overcome disadvantages mentioned above, provide a kind of flame-proof type pressure-bearing termination, it is mainly solved
The termination of high temperature and pressure of having determined shielded electric pump can bear high temperature and pressure, but can not be used as explosion-proof type termination, general
The termination of flow-through shielded electric pump is explosion-proof type termination, but the problems such as can not bear high temperature and pressure.The utility model
Purpose be achieved in that a kind of flame-proof type pressure-bearing termination by：Connection bolt, ceramic insulation set, flame proof pressing plate, wiring
Plate, gasket, insulating washer, stop washer, threaded flame-proof type face are constituted.Ceramic insulation set is welded on connection bolt, and ceramics are absolutely
Edge, which is put on, is welded with flame proof pressing plate, and flame proof pressing plate and terminal plate are equipped with threaded flame-proof type face, flame proof pressing plate by threaded flame-proof type face with
Terminal plate is connected, and gasket is housed between flame proof pressing plate and terminal plate, felt pad is housed on ceramic insulation set and flame proof pressing plate
Circle is equipped with stop washer between flame proof pressing plate and terminal plate.The product is made pottery due to being welded with ceramic insulation set on connection bolt
Be welded with the pressing plate of threaded explosion suppresion surface on porcelain insulation sleeve, can form threaded flame-proof type face, flame proof pressing plate by threaded flame-proof type face with connect
Line plate connects, and equipped with gasket, insulating washer, forms high pressure sealing, stop washer is housed, flame proof pressing plate can be prevented and connect
Loosening is generated between line plate, bonding strength is high, and thermal shock resistance is good, ensure that the integrality on secondary pressure boundary and reliable
Property, the requirement of high temperature and pressure sealing and flame proof can be met simultaneously, easy for assemble or unload, performance safety is reliable.
Description of the drawings：
Attached drawing 1 is a kind of structural schematic diagram of flame-proof type pressure-bearing termination of the utility model.
1-2-ceramic insulation of connection bolt covers 3-flame proof pressing plate 4-terminal plate, 5-gaskets
6-insulating washer 7-stop washer, 8-threaded flame-proof type faces
Specific implementation mode：The most preferred embodiment that according to the present invention will be described in detail below with reference to the accompanying drawings, a kind of flame-proof type are held
Crimp line apparatus by：Connection bolt 1, ceramic insulation set 2, flame proof pressing plate 3, terminal plate 4, gasket 5, insulating washer 6, stop pad
Circle 7, threaded flame-proof type face 8 are constituted.Ceramic insulation set 2 is welded on connection bolt 1, and flame proof pressing plate 3 is welded on ceramic insulation set 2,
Flame proof pressing plate 3 and terminal plate 4 are equipped with threaded flame-proof type face 8, and flame proof pressing plate 3 is connected by threaded flame-proof type face 8 with terminal plate 4,
Gasket 5 is housed between flame proof pressing plate 3 and terminal plate 4, forms high pressure sealing, ceramic insulation set 2 is equipped with on flame proof pressing plate 3
Insulating washer 6 is equipped with stop washer 7, can prevent from loosening between flame proof pressing plate 3 and terminal plate 4.
Operation principle and installation:Connection bolt 1 is with ceramic insulation set 2, ceramic insulation set 2 with flame proof pressing plate 3 using ceramics
Dielectric solder seals overall structure, and Ceramic and metal joining uses active metal method, the soldering of vacuum integral high-temperature, bonding strength
Height, heat-resistant impact ensure that the integrality and reliability on secondary pressure boundary, ceramics are inorganic insulating material, do not let out trace,
For I class F insulating material F, creepage distance can be reduced, save installation space, flame proof thread pressing plate 3 uses threaded flame-proof type face 8 and connects
Line plate 4 connects to form threaded flame-proof type face by flame proof thread, while terminal plate 4 and screw clamp plate and the formation plain cushion of gasket 5 are close
Seal structure is designed according to GB150.3, and design pressure reaches as high as 35MPa, and maximum temperature is equipped with stop pad up to 200 DEG C
Circle 7 can prevent connection bolt 1 from loosening, and ceramic insulation set 2 can meet electric clearance and climb on pressing plate 3 equipped with insulating washer 6
The requirement of explosion proof of electrical distance.
