Description
Technical field
The present invention relates to valve field, more particularly to a kind of HTHP drainage spherical valve for being easy to assembling.
Background technology
Set off an explosion because the water vapour of high temperature easily produces hydrogen with the oxygen mix in factory building, therefore it is required that valve has
Have compared with performances such as high wear resistance, anti-external leakage, fire prevention, and existing high-temperature steam ball-valve dedicated, it is fixed two and three
Piece is in the majority, be connected in the middle part of bonnet and valve body, the connection of stuffing-box and valve body, fixing axle and valve body junction, be easier to produce sternly
The external leakage of weight, safety in utilization cannot ensure.The potted component used(Such as graphite after valve, middle road metallic gasket etc.)In height
Easy seal failure under warm high pressure, valve is easily set to produce serious leak, so as to cause security incident.Solve in the prior art
The certainly technical scheme of above mentioned problem, such as Application No.:2014105009322, patent name is:A kind of high-temperature steam ball valve and its
The patent of invention of assembly method, solve above mentioned problem, but still deposited the problem of following:1st, the medium entrance in valve body
Place uses pressure ring, and pressure ring uses divided ring or pendant collet, and such setting is easy to pressure ring being installed in mounting groove, so meeting
Causing pressure ring, workpiece can rock with having gap in mounting groove;2nd, between divided ring or pendant collet plus screw fix, workpiece according to
Difficulty is big, and feed consumption takes, and match-drill difficulty can not have greatly any deviation;3rd, when bolt gland junction is in vibration, punching
Hit or during the working environment such as cyclic loading, high temperature, low temperature, corrosion, the deformation of creep, stress relaxation, loosening, tired can occur for bolt
Phenomena such as labor, stress corrosion, now bolt clipping forcee will accordingly change.Expendable deformation once occurs for filler, it
Original compressed thickness cannot be returned to, causes to relatively move at gland, bolt load under pretension condition then declines, then
It can cause and leakage is produced at filler.Common method is to carry out thermal consolidating to bolt, i.e., the fastening bolt again after system heating.
Although by tightening bolt again, can solve the problem.But if undue frequently enter tightly again, " ratcheting " can be caused,
Finally make bolt failure.
