Description
Technical field
The utility model is related to a kind of small turbine axial displacement probe signal line oil-proof device.
Background technology
In electric power factory equipment, genco does not have 2 600MW units, 2 Hangzhoupro vapour NK63/71/0 small turbines of every configuration；
10 temperature signal lines and 2 axial displacement probe signal lines are provided with every small turbine from the preceding case side of small turbine
The export of one wire hole, but be due to that void ratio between signal wire is larger, in the longtime running of small turbine, rotor has been got rid of
Lubricating oil can be flowed out to along wire before on the outside of case, on the one hand, the lubricating oil of outflow has an impact to the environment in workshop, the opposing party
Face, outflow of lubrication oil holds fire hazardous, in order to grease proofing, is sealed wire hole by irrigating fluid sealant at wire hole now,
But it is due to that space between signal wire is larger, when perfusion fluid sealant, does not ensure that all uniform closely knit, the institute in all spaces
It is bad with grease proofing effect, and overhaul remove during be easy to signal wire cause damage, cause unnecessary loss,
Improve the cost of enterprise.
Utility model content
The utility model in view of the shortcomings of the prior art and there is provided a kind of simple in construction, grease proofing effect is good, protection is reliable,
A kind of small turbine axial displacement probe signal line oil-proof device of damage will not be caused to signal wire in disassembly process.
The utility model adopts the following technical scheme that realization：A kind of grease proofing dress of small turbine axial displacement probe signal line
Put, including joint, rubber sheet gasketing and nut, one end of the joint is that band taper thread end is sealingly mounted at small turbine
In the preformed hole of preceding case side, the other end is that straight joint is connected with nut, axial displacement probe signal line case before small turbine
Inner side is passed by joint, rubber sheet gasketing and nut endoporus to be arranged on the outside of preceding case, the endoporus of the rubber sheet gasketing
Diameter is less than axial displacement probe signal line external diameter, and the rubber sheet gasketing passes through the nut being screwed on joint and axial position
Move probe signal line and compress sealing.
Preferably, the nut is additionally provided with paper gasket sealing with rubber sheet gasketing.
Preferably, the joint is sealed with preformed hole by grease proofing raw material band.
Preferably, rubber sheet gasketing side is cut provided with facilitating axial displacement probe signal line to be put into the oblique of endoporus
Opening.
Due to using said structure, the present apparatus deforms to pop one's head in axial displacement by rubber sheet gasketing physical impact
Signal wire, which is in close contact, reaches sealed effect, good grease proofing effect is reached, by axial displacement probe signal line outlet
Individually sealing, improves protection reliability, while convenient maintenance, due to without using fluid sealant, will not be to letter in disassembly process
Number line causes damage.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described further below in conjunction with the drawings and specific embodiments.
As shown in figure 1, a kind of small turbine axial displacement probe signal line oil-proof device, including joint 5, rubber gasket
Piece 4, paper gasket 3 and nut 2, one end of the joint 5 are to be sealingly mounted at case side 6 before small turbine with taper thread end
In preformed hole 7, the joint 5 is sealed with preformed hole 7 by grease proofing raw material band, and the other end of the joint 5 is straight joint and spiral shell
Cap 2 is connected, and axial displacement probe signal line 1 passes through joint 5, rubber sheet gasketing 4, paper gasket 3 before small turbine on the inside of case
Passed with the endoporus of nut 2 before being arranged on the outside of case, the diameter of bore of the rubber sheet gasketing is less than axial displacement probe signal
Line external diameter, the rubber sheet gasketing 4 is compressed with axial displacement probe signal line by the nut 2 being screwed on joint 5 and sealed.
In this example, the preformed hole 7 of case is a φ 22 hole before small turbine, and one of joint 5 is a band of φ 22
The joint of taper, joint 5 tightly wraps sealing with the faying face of preformed hole 7 with grease proofing raw material band.Joint other end is the straight of φ 20
Joint, coordinates empty larger, one paper gasket 3 of the inside pad, it is ensured that the stress of internal rubber seal pad 4 is equal in the middle of the nut 2 of joint
Even, rubber sheet gasketing 4 is in order to reach good sealing effectiveness, and the diameter of interstitial hole is smaller, and rubber sheet gasketing side is oblique
Cut, so as to which signal wire is put into.After signal wire is put on, fastening nut, internal rubber seal pad stress deformation can be by signal
Line is firmly held tightly, reaches grease proofing effect.
Described above, only case explanation is embodied in the utility model, it is impossible to limit right of the present utility model with this
Protection domain.All equivalence changes made according to present utility model application claims and description and modification, all exist
In the range of the utility model protection.
