Description
Technical field
The invention belongs to mechanical detection method fields, and in particular to a kind of detection method of valve.
Background technique
Safety valve is one kind more special in valve, its particularity is because of safety valve be different from other valves only
Play the role of switch, it is often more important that play the safety of protection equipment.When system pressure is more than specified value, safety valve is beaten
Open, a part of gas/fluid in system be discharged into outside atmosphere/pipeline, make system pressure be no more than permissible value, thus guarantee be
Because of hypertonia accident does not occur for system.Safety valve is usually used in crane, and weight is played in the control mechanism of crane
The control action wanted.After safety valve is used for a long time, abrasive dust can be just generated between each mechanical structure, abrasive dust is easily accessible
On the sealing surface of safety valve, after sealing surface stress, abrasive dust can scratch sealing surface.
The mesh number of abrasive dust is typically small, easily adheres on sealing surface, and after sealing surface is separated with abrasive dust, abrasive dust may
It is difficult to be discharged, is easy long-term existence on soft face, when the detection to abrasive dust is unqualified, abrasive dust is easy to be retained in sealing surface
On, and then stiff dough will be scratched again when rubbing again and plow deeper longer zanjon on soft face, but abrasive dust diameter it is smaller when,
Be difficult to observe by the naked eye the position of abrasive dust, so be difficult to for abrasive dust carry out it is fully erased, if directly to the mill on sealing surface
Bits are comprehensively wiped, and be will lead to abrasive dust and are slided along sealing surface, and then cause secondary injury to sealing surface.
Summary of the invention
