32 sideslips are enclosed, connecting tube 4, which is gradually increased close to the thickness of the side wall of one end of pressure sensor 33 from top to bottom end, makes pressure
The reaction of sensor 33 is sensitiveer, when dismantling pressure detection structure 2, turns fixing sleeve 23, by fixing sleeve 23 and installation pipe
21 disassemblies, convenient for dismantling installation pipe 21, fixing sleeve 23 is positive hexagonal structure, makes to dismantle fixing sleeve 23 more convenient.
Pressure detection structure 3 of the invention cooperates the use of sealing structure 7, convenient in the injection slurry of the inside of connecting tube 4
When lacking, flow-guiding structure 6 is controlled by sealing structure 7 and connecting tube 4 is connected, makes the inside of seawater injection connecting tube 4, it is local
When stressor layer missing or standpipe device separate, when there is the case where mud is largely lost in standpipe device, filled out in time by seawater
Permit, effectively prevent the collapsing of the riser systems under vacuum state, improve the quality of oil exploitation；Pressure detection structure 3 and company
Adapter tube 4 is detachably connected, while pressure detection structure 3 cooperates wire structures 2 to be connected to sealing structure 7, improves waterproof performance,
The use for cooperating sealing structure 7 simultaneously, keeps the repair and maintenance of safety valve more convenient；Flow-guiding structure 6 and sealing structure 7 are detachable
Connection effectively prevents the inside of expense bits blocking flow-guiding structure 6 and its connecting tube 4 when injecting seawater filling, improves peace
The service performance of full valve.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, and the description in above embodiment and specification only illustrates the present invention
Principle, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these variation and
Improvement is both fallen in the scope of protection of present invention.The claimed scope of the invention is by appended claims and its equivalent
Object defines.
