Description
Technical field
The utility model is related to oil equipment field, specifically a kind of multi-state sealing ring for petroleum machinery.
Background technology
With the development of industrial technology, for the production efficiency more and more higher of oil, and the thing followed is answering for equipment
Miscellaneous and measure of precision is constantly lifted, and the working environment of equipment is more and more harsher, for example, under hyperbaric environment, the pressure in valve can
20000PSI (138Mpa can be reached）, for such a pressure, sealing is generally realized using particularly customized sealing ring, however, special
Its production cost of the sealing ring not customized is expensive, stock condition is difficult, is unfavorable for the maintenance and operation of oil equipment.
The content of the invention
The purpose of this utility model is that can resist high-low pressure fluctuation there is provided one kind, have particle, corrosivity and oil gas close
Seal the sealing ring of mixture condition.
In order to achieve the above object, the utility model is realized in：
A kind of multi-state sealing ring for petroleum machinery, it is by low pressure seal ring body, high pressure sealing ring body and sealing gasket
Ring body is spliced successively；Wherein, low pressure seal ring body is the elastic ring body with one of lip shape groove, high pressure sealing ring
Body is the ring body with two to four road lip shape grooves, after high pressure sealing ring body is PTFE materials mixed carbon fibre or glass dimension
Constitute, sealing gasket ring body is the ring body that PEEK organic plastics or austenitic stainless steel are made.
The described multi-state sealing ring for petroleum machinery, is set between low pressure seal ring body and high pressure sealing ring body
There is gasket ring, gasket ring is provided between high pressure sealing ring body and sealing gasket ring body.
This seal ring assembly bears the seal ring body of different pressures and with the anti-grain structure of multiple tracks, Neng Goushi including twice
Answer different pressures situation and the demand of working environment.
Brief description of the drawings
Fig. 1 is the structural representation of this seal ring assembly.
Embodiment
The utility model is further illustrated below by way of specific embodiment.
As shown in figure 1, a kind of multi-state sealing ring for petroleum machinery, it is by low pressure seal ring body 1, high pressure sealing ring
Body 2 and sealing gasket ring body 3 are spliced successively；Wherein, low pressure seal ring body 1 is the elasticity with one of lip shape groove 11
Ring body, high pressure sealing ring body 2 is the ring body with two to four road lip shape grooves 21, and high pressure sealing ring body 2 is PTFE materials
Constituted after mixed carbon fibre or glass dimension, sealing gasket ring body 3 is the ring body that PEEK organic plastics or austenitic stainless steel are made.
In above-mentioned sealing ring, low pressure seal ring body 1 uses the sealing ring of one of lip shape, and material hardness is softer, has very
Good elasticity, can be achieved low pressure seal, stops up function to having containing graininess sand grains, for high pressure operating mode, this low pressure seal circle
Crush resistance strength is not enough, the gap of bar and low pressure seal ring body is reduced by high pressure sealing ring body stress deformation, so that will not
There is the situation for damaging low pressure seal ring body by pressure；And different materials may be selected for operating mode and are used as low pressure seal ring body material.
In above-mentioned sealing ring, high pressure sealing ring body 2 is using the sealing ring of two to four road lip shapes, and material hardness is harder to be led to
25% or so carbon fiber is added frequently with PTFE or glass is tieed up.Super-pressure 138MPA operating mode can be achieved, lip trench design can
It is effectively secondary to the progress of graininess sand grains to stop up, so that sealing ring will not be damaged；Same high pressure sealing ring body crush resistance strength
Not enough possibility, the situation for reducing pressure is realized by the gap of sealing gasket ring body and bar, from without damaging high densification by pressure
The situation of seal ring body.
In above-mentioned sealing ring, the material of sealing gasket ring body 3 uses PEEK organic plastics or austenitic stainless steel；Its effect is not
Can the higher stem surface of scratch hardness.
The described multi-state sealing ring for petroleum machinery, is set between low pressure seal ring body and high pressure sealing ring body
There is gasket ring, gasket ring is provided between high pressure sealing ring body and sealing gasket ring body.
This sealing ring bears the seal ring body of different pressures and with the anti-grain structure of multiple tracks including twice, can adapt to not
With pressure condition and the demand of working environment.
