Description
Technical field
The utility model belongs to pressure vessel using field, is related to the protection that dielectric leakage occurs for flange sealing surface.
Background technique
The sealing performance of flange seal is most important for the sealing of pressure vessel, and medium is let out by what flange gap occurred
Leakage is that pressure vessel industries leakage is most extensive and one of the most common type leakage way, China's major part pressure vessel are to operate in face
High-temperature bearing equipment under hydrogen environment, what main seal leaned on is joint seal of flanges, but due to most of in-service pressure
Container is shaken due to caused by medium, and gasket failure, the pressing force factors such as not enough will cause the media such as hydrogen, hydro carbons between flange
Leakage between flange gap.It is reported that the generally existing equipment such as with some high-temperature hydro-refining reactors and heat exchanger of this phenomenon
Flange on.Once leakage, which occurs, will cause the accidents such as fire even explosion and cause heavy losses.
Summary of the invention
We will solve the problems, such as: prevent inservice pressure vessel flange occur dielectric leakage when caused by fire and explosion
Risk.
The utility model provides flange sealing surface leakage blow device, and structure has: distribution of steam tube assembly 4 and distribution
Pipe support component 5 and its movable buckle 6；The distribution of steam tube assembly 4 be by coil pipe 7, connecting flange 8, tee tube 9, into
Tracheae 10 is composed；Wherein 7 inside border of coil pipe is uniformly full of purge hole, and coil pipe 7 is divided to for two valves, between pass through connection method
Orchid 8 is connected by screw bolts；Coil pipe 7 connects air inlet pipe 10 and enters pressurized vapor；The distributor pipe support component 5 is by cranse
11, support plate 1, support plate 2 13 are composed；Wherein cranse 11 is divided to for two valves, is bolted between two valves.
The application method of flange sealing surface leakage blow device: it is divided to two the cranse 11 in distributor pipe support component 4 first
Valve is stuck on the ring flange of lower flange 2, and make-up is connected by screw bolts between two valves；Again passing through company between two valves of coil pipe 7
Acting flange 8 is connected by screw bolts make-up；Purge hole above coil pipe 7 must between centering flange 1 and flange 2 gap middle part
Position；After position and orientation adjustment are suitable, support plate 2 13 is connect with coil pipe 7 using movable buckle 6, fixed steam point is supported
4 component of stringing；It is connect by air inlet pipe 10 with external steam, steam is uniformly purged by the purge hole border above coil pipe 7
Gap between the flanges dispels the medium leaked between flange.
Effective protection is carried out to equipment the utility model has the beneficial effects that can guarantee, prevents pressure container flange medium
Fire caused by leaking and explosion；Versatile, suitable for various different size situations the processing of flange dielectric leakage and protection；
It is easy to operate, securely and reliably, reduce the operation level and risk requirement of construction personnel when to flange dielectric leakage.

Specific embodiment
In conjunction with attached drawing, the utility model is further illustrated.
The utility model provides flange sealing surface leakage blow device, as shown in Fig. 2, its structure has: distribution of steam pipe
Component 4 and distributor pipe support component 5 and its movable buckle 6；The distribution of steam tube assembly 4 be by coil pipe 7, connecting flange 8,
Tee tube 9, air inlet pipe 10 are composed, as shown in Figure 3；Wherein 7 inside border of coil pipe is uniformly full of purge hole, and coil pipe 7 divides
For two valves, between be connected by screw bolts by connecting flange 8, as shown in figure 4, such structure is convenient for handling；Coil pipe 7 passes through company
Tracheae 10 is tapped into pressurized vapor；The distributor pipe support component 5 is by cranse 11, support plate 1, support plate 2 13
It is composed, as shown in Figure 7, Figure 8；Wherein cranse 11 is divided to for two valves, is bolted between two valves, as shown in Figure 9；In this way
Structure convenient for handling.
Flange sealing surface leak blow device how to use:as shown in Figure 1, first in distributor pipe support component 4
Cranse 11 is divided to two valves to be stuck on the ring flange of lower flange 2, make-up is connected by screw bolts between two valves, as shown in Figure 9；Again disk
Make-up is connected by screw bolts by connecting flange 8 between two valves of pipe 7；Purge hole above coil pipe 7 must centering flange 1 and method
Orchid 2 between gap intermediate position, position and orientation adjustment it is suitable after, support plate 2 13 and coil pipe 7 use movable buckle 6 connect
