Abstract
The utility model relates to a high pressure ball type compensator for thick oil gas filling, which is characterized in that a sphere is arranged in a compensator body, a sealing ring is arranged between the outer surface of the sphere and the compensator body, the sphere is clamped in the compensator body by the sealing ring and a gland bush, and the compensator body and the gland bush can be tightly fixed by screw bolts and screw nuts. The sphere can rotate in the sealing ring, and the centers of the sphere, the compensator body and the gland bush are all provided with through holes. The utility model has the characteristics of high capacity of compensation, favorable sealing performance, high temperature resistance, high pressure resistance, steel saving, etc.
Description
The utility model is a kind of high pressure spherical compensator that is used for oil-field thick-oil exploitation steam injection system pipeline temperature compensation.
Annotating vapour is a kind of technology of high temperature and high pressure steam being injected oil reservoir extraction viscous crude, its vapor pressure PN≤MPa, the temperature compensation of steam injecting pipe is realized in temperature t≤360 ℃ under this high pressure and high temperature, (as curved curved youngster on pipeline) was very difficult with all types of in the past compensators.
The purpose of this utility model provides a kind of high pressure spherical compensator, makes it can realize the temperature compensation of steam injecting pipe under the situation of high temperature, high pressure.
The purpose of this utility model is achieved in that
In body, be provided with a spheroid, between the outer surface of spheroid and the body seal ring is arranged, spheroid is stuck in the body, and body and gland are tightened up with bolt, nut by seal ring and gland, spheroid can rotate in seal ring, and all there is through hole at spheroid, body and gland center.
Ring structure compresses sphere for the rear and front end wedge shape sealing ring, and the centre adds flexible sealing ring.
The utility model compensation ability is big, than using the used quantity of other type compensator to lack, saves steel and project investment, and good seal performance can high temperature resistant, high pressure.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is user mode figure of the present utility model.
Among the figure, 1, body, 2, spheroid, 3, wedge shape sealing ring, 4, seal ring, 5, gland, 6,7, bolt, nut, 8, the steam pipe road, 9,10, compensator.
See Fig. 1, in the body 1 through hole is arranged, one end outer surface is taper, and itself and steam pipe road 8 connects, and the other end is cylindrical, and is provided with flange, in the gland 5 cone-shaped hole is arranged, and the end that endoporus is big is provided with flange, a end that endoporus is little is pressed to body 1.In the spheroid 2 through hole is arranged, one end outer surface is spherical, the other end is cylindrical, a columniform termination steam pipe road 8, the ball external diameter of spheroid is about 1.4:10 with the ratio of ball neck external diameter, and spheroid 2 is arranged in the body 1, and between body 1 and spheroid 2, add seal ring, seal ring is three seal rings, 3 fens forward and backward being pressed on the outer surface of spheroid of two wedge shape sealing rings, and the centre is a flexible sealing ring 4.Flange hole and nut 7 that bolt 6 passes on body and the gland screw togather, and compensator is fixed, and spheroid 2 can rotate 30 ° in seal ring.
Body and spheroid, gland all are forging in this smash compensator, No. 20 steel of material selection or be better than the material of No. 20 steel, the ball plating hard chromium on surface is with anti-corrosion and the friction torque that reduces to produce when spheroid rotates, the material of seal ring is the withstand voltage PN 〉=30MPa of asbestos composite material, heatproof t 〉=400C °, the intermediate seal ring material is an Expanded graphite, heatproof t 〉=600 ℃, and bolt material is selected 30CrMoA or 35CrMoA for use.
Its specification of this smash compensator is the DN50-100mm4 kind, is connected with pipeline and can welds, and also can add flange at the two ends of compensator, connects with bolt and nut, and working pressure is PN≤20MPa, saturated-steam temperature t≤360 of relevant pressure ℃.
See Fig. 2, during use that two smash compensators 9,10 are relative.Be welded in the bend place in steam pipe road 8, when steam pipe road 8 is out of shape owing to high temperature (as shown in phantom in FIG.), the spheroid 2 of smash compensator rotates a certain angle automatically, thereby has compensated the thermal expansion distortion of pipeline.
Claims (2)
1, a kind of thick oil filling vapour high pressure spherical compensator, it is characterized in that: in body, be provided with a spheroid, between the outer surface of spheroid and the body seal ring is arranged, by seal ring and gland spheroid is stuck in the body, and body and gland are tightened up with bolt, nut, spheroid can rotate in seal ring, and all there is through hole at spheroid, body and gland center.
2, high pressure spherical compensator as claimed in claim 1 is characterized in that; Ring structure is: forward and backward twice wedge shape sealing ring compresses sphere, and the centre adds flexible sealing ring.
