Description
Technical field
It the utility model is related to a kind of pyrocondensation sealing cap permeability test equipment.
Background technology
The pyrocondensation sealing cap of cable includes thermal shrinkable sleeve, valve and gas cap, and it is encapsulated in the termination of medium and high voltage cable, works as cable
Middle inert gas occur and when gas reaches certain pressure, sealing cap valve can be vented automatically, to protect cable, be avoided the occurrence of swollen
Swollen phenomenon.Therefore the gas permeability of pyrocondensation sealing cap is critically important to realizing for its function, but to not having related effective ways at present.
The method used now is to prepare a metal tube, seals a pyrocondensation sealing cap respectively at its both ends, lower end is immersed in the water, on
End is opened valve and inflated inside, see pressure gauge pressure change and water in whether bubbling judges whether it is vented and assorted
It is vented under pressure, it is therefore desirable to the metal tube of suitable outer diameter is equipped with for the pyrocondensation sealing cap of more than 40 individual specifications, and need to be various
A readable pressure gauge is connected on the metal tube of specification, method is inapplicable and difficult to realize.
Utility model content
The purpose of this utility model is to provide a kind of pyrocondensation sealing cap permeability test equipment for being capable of practical operation.
The technical scheme for realizing the utility model purpose is contracting sealing cap permeability test equipment, including compressed air cylinder,
One pressure regulator valve, connecting tube, snap joint, air manometer, sealing ring, nut, spring, pad and water tank；First pressure regulation
Valve is arranged between compressed air cylinder exit and connecting tube, and connecting tube middle-end sets air manometer；The nut is provided with
Internal thread and the seal groove matched with sealing ring, the snap joint include the screw rod and external thread sleeve of engagement, external thread sleeve
Screw thread engaged with the internal thread of nut；The size of the spring and pad and the size phase of the external thread sleeve of snap joint
Match somebody with somebody.
Test equipment also includes the second pressure regulator valve；Second pressure regulator valve by snap joint be arranged on the first pressure regulator valve with
In connecting tube between air manometer.
After employing above-mentioned technical proposal, the positive effect that the utility model has is：Equipment of the present utility model is set
Meter is reasonable, it is not necessary to is sealed in test process, it is not required that prepare the metal tube of a variety of specifications, it is workable,
Good test effect.
Brief description of the drawings
In order that content of the present utility model is easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail to the utility model, wherein
Fig. 1 is device structure schematic diagram of the present utility model.
Fig. 2 is enlarged drawing at Fig. 1 A.
Fig. 3 is the explosive view of snap joint, metal valve, spring, pad, sealing ring and nut.
