Abstract
The utility model discloses the gland seal device of a kind of core level centrifugal blower, including sealing gasket, described sealing gasket is connected with casing bolt by a briquetting, have between inner ring and the outer ring of described sealing gasket one isolate out partly cut open seam, described partly cuing open is stitched and the radial line A at an angle of sealing gasket.The quantity of described sealing gasket is 2 pieces.Have employed the gland seal device of core level centrifugal blower of the present utility model, seam is cutd open by arranging one and half on sealing gasket, similar gland sealed structure design, the connected mode of the fixing employing presser type of sealing device and housing, for portable sealed pad [formula of partly cuing open for disconnecting], it is convenient to change.
Description
Technical field
This utility model relates to a kind of sealing device, particularly relates to a kind of core level for nuclear power plant and is centrifuged wind
The gland seal device of machine.
Background technology
Existing nuclear power plant core level centrifugal blower, stretches out in rotating shaft and can arrange gland seal device at housing, this close
Seal apparatus includes an all-in-one-piece sealing gasket and for the ring washer of pinch seal pad and fixture block, and the sealing gasket of this structure exists
Axial dimension is longer, parts multiple on main shaft need to be disassembled the most replaceable when changing sealing gasket, has replacing sealing gasket not
Shortcoming easily.Axial dimension length will make main shaft cantilever part lengthen, and then make blower fan critical speed reduce, and affect the steady of blower fan
Qualitative.Or in order to improve critical speed overstriking main shaft, make major axis size strengthen.
Utility model content
For overcoming drawbacks described above, this utility model aims to provide a kind of can replacing conveniently, and the core level of stable performance is centrifuged wind
The gland seal device of machine.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: the gland seal of a kind of core level centrifugal blower
Device, including sealing gasket, described sealing gasket is connected with casing bolt by a briquetting, the inner ring of described sealing gasket and outer ring it
Between have one isolate out partly cut open seam, the described radial line A at an angle partly cuing open seam and sealing gasket.
The quantity of described sealing gasket is 2 pieces.
Have employed the gland seal device of core level centrifugal blower of the present utility model, by arranging one and half on sealing gasket
Cuing open seam, similar gland sealed structure design, the connected mode of the fixing employing presser type of sealing device and housing, for portable
Sealing gasket [formula of partly cuing open for disconnecting], just can change after only need to dismantling the fixing bolt of axle envelope, be very convenient to.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the Facad structure schematic diagram of sealing gasket.
In figure: 1-sealing gasket, 2-briquetting, 3-casing, 4-partly cuts open seam.
Detailed description of the invention
As depicted in figs. 1 and 2, the utility model discloses the gland seal device of a kind of core level centrifugal blower, including one
Individual sealing gasket 1, described sealing gasket 1 is connected with casing 3 bolt by briquetting 2, it is characterised in that the inner ring of described sealing gasket 1 is with outer
Have between circle one isolate out partly cut open seam 4, the described radial line A at an angle partly cuing open seam 4 and sealing gasket 1.This practicality is new
Sealing gasket 1 in the gland seal device of the core level centrifugal blower described in type is dissection type, and traditional sealing gasket 1 is monoblock type,
Traditional sealing gasket 1, when changing, must disassemble the most replaceable parts multiple on main shaft, owing to being split type structure, only needs
Just can change sealing gasket 1 after the fixing bolt of dismounting axle envelope, greatly facilitate the maintenance of equipment, greatly reduce maintenance
Time.Concrete substitute mode is pulled open sealing gasket 1 from partly cuing open to stitch 4 exactly, then takes off from main shaft.
Another innovative point of the gland seal device of core level centrifugal blower described in the utility model is described sealing
The quantity of pad 1 is 2 pieces.
Claims (2)
1. a gland seal device for core level centrifugal blower, including a sealing gasket (1), described sealing gasket (1) passes through briquetting
(2) it is connected with casing (3) bolt, it is characterised in that there is between inner ring and the outer ring of described sealing gasket (1) one and isolate out
Partly cut open seam (4), the described radial line A at an angle partly cuing open seam (4) and sealing gasket (1).
The gland seal device of core level centrifugal blower the most according to claim 1, it is characterised in that described sealing gasket (1)
Quantity is 2 pieces.
