Abstract
Dual spring energy-storage sealing ring is a kind of sealing ring being used for pressure regulating valve valve seal, and in valve produces, under the conditions of special operation condition, such as: in the case of low leakage, ultralow temperature or special media, General Purpose Rubber class O-ring can not meet seal request.The unique characteristic of dual spring energy-storage sealing ring, solves harsh operating mode lower valve sealing problem, it is achieved valve body seals No leakage.Dual spring energy-storage sealing ring is the pressure assisted seal device that material is polytetrafluoroethylene (PTFE) chuck, with corrosion resistant metal energy storage spring, U-shaped sheet metal and the spiral metal ring of two kinds of forms in its structure composition.Dual spring energy-storage sealing ring can realize " self sealss ", i.e. its sealing property raises with the rising of pressure.
Description
Technical field
The utility model relates to a kind of sealing ring, especially a kind of dual spring sealed circle.
Background technology
In fluid-transporting tubing and relevant device, as a example by delivery industry gas medium pipeline, gas pipeline carried
Commonly used pressure-regulating device-pressure regulator in journey, pressure regulator is under harsher working condition, such as low leakage, ultralow temperature
Or in the case of special media, the sealing property of valve body tends not to reach requirement.
Content of the invention
Dual spring energy-storage sealing ring is a kind of new structure sealing ring, based on polytetrafluoroethylene (PTFE) chuck, and arranges
Corrosion resistant metal energy storage spring, U-shaped sheet metal and the spiral metal ring of two kinds of forms.
Its technical scheme is: the sealing ring with energy-storaging spring can realize " self sealss ", and i.e. its sealing property is with pressure
The rising of power and raise.In addition, sealing ring can reduce friction, service life is longer, can be suitably used for harsh environment condition, the
U-shaped sealing together, direct contact medium pressure, rely on pressure medium and rely on spring force, it is achieved self sealss, second spiral
Becket, by the crimp of indirectly pressure medium and first sealing ring, defines secondary seal.
Sealed jacket use material: polytetrafluoroethylene (PTFE), energy-storaging spring use material: nickel-base alloy.
Dual sealing structure, greatly improves the sealing property of pressure regulator valve valve body itself, according to different operating modes and
Environmental condition reasonably selects spring energy-storage sealing ring material.Through overtesting and detection, dual spring energy-storage sealing ring is various
Intact sealing is achieved under harsh working condition.
Brief description
Accompanying drawing 1 ring structure figure
Ring structure figure after accompanying drawing 2 compression
Detailed description of the invention
Dual spring energy-storage sealing ring by with the corrosion resistant metal energy storage spring of two kinds of forms, U-shaped sheet metal and
Spiral metal ring realizes, implements to seal with the pressure servicing unit with polytetrafluoroethylene (PTFE) chuck.
