Description
Technical field
The present invention relates to a kind of explosion-proof fixed froth installations, belong to fire-fighting equipment technical field.
Background technique
Fixed froth installation is the widely used fire-fighting equipment on lease tank.Currently, most of foam fire-fighting is mounted in
It is formed using rigid connections such as steel pipe screw threads, it is not convenient enough in installation and maintenance, simultaneously as this connection cannot bear tank
The pulling force and torque that wall deformation generates occur the explosion time conveying device and will receive intense impact and damaged when petroleum storage tank catches fire
Fire foam can not be conveyed, fire extinguishing effect cannot be effectively acted as.For this problem, existing patent CN 2766892Y is by adopting
Tank body and delivery pipe are connected with flexible explosion-proof connector, although conveying device tolerance impact energy can be solved to a certain extent
The problem of power difference, but there are still the probabilities that explosion time is destroyed.Since the flexible antiriot device of patent is using laterally setting, explosion time
The probability being destroyed is larger, and can not rule out conveying device and tank body connecting portion, especially at foam inlet port, is exploded
Entirety is destroyed or is fallen off.After being destroyed, although the conveyance conduit of integrated support is intact, but still it is unable to complete conveying task.
The prior art mostly uses the method preventing mean for increasing pipeline local compliance to be destroyed.But device is destroyed
Root be that tank skin when fire explosion near installation foam maker is generated moderate finite deformation by impact, cause to be fixed on tank
Pipe deforming fracture on wall.The prior art only treats the symptoms and does not account for effecting a permanent cure.In addition, blind flange force can be generated at pipeline turning,
Very big load, the safety for reducing pipeline life and using can be caused to pipeline.
