Embodiment
Below against accompanying drawing, by the description to embodiment, embodiment of the invention is made further details of
Explanation.
As depicted in figs. 1 and 2, the device for being used for valve housing leak detection, including water tank 1, lift platform 2, platen 3, gas
Cylinder 4, flange seal are first 5, fluid connection tube 8 and valve housing support frame 9.
Platen 3 is a slab construction, and platen 3 is arranged in water tank 1, and water tank 1 is used to deposit clean water by valve to be detected
Gate housing immerses, and water tank 1 is transparent cabinet, is easy to observe；In water tank 1 lift platform 2, lift platform are provided with the lower section of platen
It is steady for scissors fork elevating frame, lifting.
Cylinder 4 and valve housing support frame 9 are each attached to the top of platen, and flange seal first 5 is used for sealed valve housing
Valve adpting flange 6, flange seal head is fixed on the valve connection method of the outer end of piston rod, flange seal head and valve housing
Orchid is oppositely arranged；Valve housing support frame 9 is liftable support frame, for supporting positioning valve housing, valve housing support
The top of frame is provided with curved support plate, and valve housing is placed on curved support plate, and positioning is reliable；Valve housing support frame lifts just
In picking and placeing valve housing, operation is extremely simple.
Cylinder 4 and flange seal first 5 are a pair, are symmetricly set on the both sides of valve housing.Pass through a pair of flange seal heads
The valve adpting flange of valve housing opposite sides is sealed.
The top of platen 3 is provided with the fluid connection tube 8 being connected with the bonnet adpting flange 7 of valve housing, is connected by liquid
Pipe 8 injects coloured liquid into the valve housing of sealing, then the valve housing of sealing is dropped to below the water surface of water tank,
Water in Water Tanks color change is observed, can easily identify leakage point using color contrast, detection is efficiently.
Valve connecting flange faces are corresponded on flange seal first 5 and are provided with annular groove 501, center is provided with annular groove 501
Plug 503, the bottom of annular groove are provided with rubber blanket 502, and rubber blanket 502 is provided with annular protrusion, sealed reliable.
Center plug 503 is provided with rubber sleeve 504, and rubber sleeve 504 is hollow, and the outer end of rubber sleeve, which is provided with, to be used for and valve
