Abstract
The utility model discloses a composite filler sealing structure used for an ultrahigh-pressure valve. The composite filler sealing structure comprises a lower filler, a filler spacer ring, an O-shaped ring, an upper filler and a valve cover, the lower filler, the filler spacer ring, the O-shaped ring and the upper filler are sequentially arranged in the valve cover from bottom to top, the lower filler is a first sealing layer, the upper filler and the O-shaped ring are a second sealing layer, a side hole is formed in the valve cover, and sealing grease is injected through the side hole and enters a position of the upper filler to realize auxiliary sealing. By the above mode, the composite filler sealing structure has more stable sealing effect and is higher in safety performance.
Description
Technical field
The utility model relates to oil field development technical field, particularly relates to the composite filling sealing configuration of a kind of ultrahigh pressure (20000psi and more than) valve.
Background technique
At present, the sealing configuration at common high pressure valve stuffing box place is single sealing configuration, only has one sealing, though this sealing configuration can be realized good sealing under normal circumstances, but its Safety performance is lower.Main cause is: in the long-term using process of valve, filler, under the effect of high pressure, Korrosionsmedium, can lose efficacy gradually, if only have one sealing, once this road sealing was lost efficacy so, whole valve cannot normally be used again.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of composite filling sealing configuration for Super high pressure valve, has more stable sealing effect, and Safety performance is higher.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of composite filling sealing configuration for Super high pressure valve is provided, comprise: lower filler, filler spacer ring, O type circle, upper filler and valve gap, described valve gap internal diameter is disposed with lower filler, filler spacer ring, O type circle, upper filler from bottom to up, described lower filler is the first sealing layer, described upper filler and O type circle are the second sealing layer, on described valve gap, be provided with a side opening, by side opening, inject seal gease, seal gease enters upper filler place by filler spacer ring and realizes auxiliary seal.
In preferred embodiment of the utility model, described lower filler is spring energy-storage circle, and spring energy-storage circle has good sealability and higher intensity, can under the operating mode of ultrahigh pressure, stablize use.
The beneficial effects of the utility model are: the utility model adopts double sealing structure, and when filler occurs partial failure or leaks instantly, upper filler and O type circle can be realized sealing for the second time, thereby increase sealing and the stability of Super high pressure valve.Also can by the side opening of valve gap, inject seal gease simultaneously and realize auxiliary seal, can more effectively guarantee the normal use of valve.
Accompanying drawing explanation
Fig. 1 is that the utility model is for the inside sectional structure schematic diagram of the composite filling sealing configuration of Super high pressure valve.
In accompanying drawing, the mark of each parts is as follows: 1, lower filler, 2, filler spacer ring, 3, O type circle, 4, upper filler, 5, valve gap, 6, side opening, 7, valve rod.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 1, the utility model is embodiment comprise: a kind of composite filling sealing configuration for Super high pressure valve, comprise: lower filler 1, filler spacer ring 2, O type circle 3, upper filler 4 and valve gap 5, described valve gap 5 internal diameters are disposed with lower filler 1, filler spacer ring 2, O type circle 3, upper filler 4 from bottom to up, described lower filler 1 is the first sealing layer, described upper filler and O type circle are the second sealing layer, on described valve gap 5, be provided with a side opening, by side opening, inject seal gease, seal gease enters upper filler 4 places by filler spacer ring 2 and realizes auxiliary seal.
Furtherly, described lower filler is spring energy-storage circle.
For the composite filling sealing configuration of Super high pressure valve in use, valve gap 5 and valve rod 7, in the state of closely cooperating, when filler 1 lost efficacy instantly, can be realized sealing by upper filler 4 and O type circle 3 to the utility model, thus the normal use of assurance valve.Also can inject seal gease by side opening 6, seal gease enters upper filler 4 places by filler spacer ring 2 and realizes auxiliary seal simultaneously.The utility model structure is for the sealing at ultrahigh pressure (20000psi and more than) valve rod stuffing box place, and with respect to conventional valve packing, this structure has more stable sealing effect, and Safety performance is higher.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
Claims (2)
1. the composite filling sealing configuration for Super high pressure valve, it is characterized in that, comprise: lower filler, filler spacer ring, O type circle, upper filler and valve gap, described valve gap internal diameter is disposed with lower filler, filler spacer ring, O type circle, upper filler from bottom to up, described lower filler is the first sealing layer, and described upper filler and O type circle are the second sealing layer, are provided with a side opening on described valve gap, by side opening, inject seal gease, seal gease enters upper filler place by filler spacer ring and realizes auxiliary seal.
2. the composite filling sealing configuration for Super high pressure valve according to claim 1, is characterized in that: described lower filler is spring energy-storage circle.
