Description
Technical field
The utility model is related to sealing device field, more particularly to a kind of bidirectional integral ultralow temperature sealing ring.
Background technology
In ultralow temperature industry such as LNG, LPG, LEG etc., the resistance to low temperature of equipment is typically required at -196 °C~+50 °C,
Therefore to ultralow temperature the equipment part such as reliability of gate valve, check-valves, ball valve etc., adaptability, stability and sealing requirements
More and more higher.
Sealing ring as ultralow temperature equipment an indispensable critical piece, it is reliability to ultralow temperature equipment, steady
Qualitative guarantee is played an important role and ensured.And ultralow temperature equipment sealedly designs Main Basiss API-6D- both at home and abroad at present
2008 perform, using AS 568A standards.
All kinds of general plugs domestic at present, which are sealed in when being used under ultralow temperature equipment, is easily caused gas leakage, and sealing effectiveness is not
It is good, although many producers are optimized to the performance of sealed structure and material, improved, some effects are achieved, but not
The condition needed for ultralow temperature equipment is reached, it is difficult to be realized and the good fit between axle, hole under ultra-low temperature surroundings, it is impossible to well
Ensure the sealing effectiveness under ultra-low temperature surroundings.
Utility model content
The purpose of this utility model is to provide a kind of can ensure the two-way of better seal effect under low Low Level environment
Integral type ultralow temperature sealing ring.
Technical solution adopted in the utility model is：
A kind of bidirectional integral ultralow temperature sealing ring, including cross section are the seal casinghousing of the ring-type of H types, seal casinghousing
Both sides are disposed as in opening, seal casinghousing being provided with above and below preloading spring, seal casinghousing in the opening of both sides up and down up and down
The opening both sides of both sides are flared out forming interior sealing lip and outer seal lip respectively.
It is circle to be further used as inside and outside the improvement of technical solutions of the utility model, interior sealing lip and outer seal lip
Arcuation.
The improvement of technical solutions of the utility model is further used as, the middle part of seal casinghousing is the main body of connection both-side opening
The both sides that solid ring portion, interior sealing lip and outer seal lip protrude from the solid ring portion of main body respectively are set.
The improvement of technical solutions of the utility model is further used as, the internal diameter and external diameter of the ring-type of two preloading springs formation are equal
It is equal, up and down both sides overlapping installation of two preloading springs in seal casinghousing.
The improvement of technical solutions of the utility model is further used as, seal casinghousing is modified ptfe material.
The improvement of technical solutions of the utility model is further used as, two preloading springs are metal spring.
The beneficial effects of the utility model：This bidirectional integral ultralow temperature sealing ring passes through up and down two on the inside of seal casinghousing
Interior sealing lip is contacted with shafting, and is provided by the preloading spring at interior sealing lip in the both up and down of shafting in pretightning force compressing
Sealing lip contact shafting is sealed, and is sealed between outer seal lip and hole system, to reach the inside and outside realization in seal casinghousing
Positive and negative two way seal, provides pressure by the pretightning force of spring, reduces the influence of ultra-low temperature surroundings, can reach good sealing
Effect.
