Abstract
The utility model discloses a rack sealer, including the casing, setting up coaxial arrangement's through-hole on the relative upper and lower two walls of casing respectively, casing upper wall through-hole outside is setting up the ascending open-ended and is adding the rubber tube, adds the vertical double-sided rack that passes from the upper and lower two wall through-holes of setting up in the rubber tube, leaves fit clearance between rubber tube and the double-sided rack, and the rack both sides in the casing are setting up the gear respectively, and two gears all mesh with the rack mutually. The utility model discloses not only can be high pressure resistant, long service life can eliminate the phenomenon of the well head that pollutes because of the rubber ring strain runs out oil moreover effectively, and is sealed effectual, need not shut down when overhauing, can not reduce the effective operating time of oil well.
Description
Technical field
The utility model belongs to and is installed on the well mouth of oil well its mechanical device that seals, particularly tooth bar sealer.
Background technology
At present, have rubber gate and rubber circle on the well mouth sealing device that uses on the well mouth of oil well more, seal by the dynamic and static frictional fit between rubber circle and the corresponding counterpart.Not only compressive resistance is low, and application life is short, and these sealing devices are when work, friction produces high temperature between rubber circle wherein and the corresponding counterpart, causes the fatigue damage of rubber circle easily, causes its loss of seal ability and runs oil, pollute well head, sealing effectiveness is relatively poor.In addition, also need to shut down when maintenance, replacing rubber circle, reduced the effective time of oil well, influence oil well output.
Summary of the invention
The purpose of this utility model is to provide a kind of tooth bar sealer, not only can be high pressure resistant, and long service life; and can eliminate effectively because of the rubber circle strains and run the phenomenon that greasy dirt dyes well head; good sealing effect need not shut down during maintenance, can not reduce the effective time of oil well.
The purpose of this utility model is achieved in that a kind of tooth bar sealer, comprise housing, the through hole of coaxial arrangement is being set respectively on relative upper and lower two walls of housing, housing upper wall through hole outside is being provided with the sebific duct that adds of upward opening, add the two-sided tooth bar that passes from the upper and lower two wall through holes of housing vertically is being set in the sebific duct, add between sebific duct and the two-sided tooth bar and leave fit clearance, the tooth bar both sides in housing are being provided with gear respectively, and two gears all are meshed with tooth bar.
When the utility model uses, it is installed on the well mouth of oil well that needs sealing, in adding sebific duct, add wear-resisting, high-temperature plastic, drive on the tooth bar by oil pumper, the following reciprocating motion, the gear of rack drives both sides rotates, because two gears all are meshed with tooth bar, guaranteeing that tooth bar is positioned at adds the sebific duct center, tooth bar and the phenomenon that adds the sebific duct wall friction can not appear, when tooth bar moves up and down, constantly drive the glue that adds in the sebific duct and enter in the housing, around the sealing rack and pinion from adding the fit clearance of being stayed between sebific duct and the two-sided tooth bar, good sealing effect has thoroughly been eliminated the oil well mouth contamination phenomenon that causes because of rubber circle strain race oil.The utility model has changed rubber circle and the dynamic and static friction matching relation between the counterpart in the past accordingly, does not have the frictional heating phenomenon, not only can be high pressure resistant, and long service life.When if the glue between the rack and pinion has wearing and tearing, only need constantly to replenish glue in the housing and get final product, and need not shut down assurance high output of oilwell stable yields by adding sebific duct.
Description of drawings
Fig. 1 looks cross-sectional view for master of the present utility model, and Fig. 2 is a side-looking structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, a kind of tooth bar sealer, as shown in Figure 1 and Figure 2, comprise housing 2, the through hole of coaxial arrangement is being set respectively on relative upper and lower two walls of housing 2, what housing 2 upper wall through holes outsides had been provided with upward opening adds sebific duct 4, add the two-sided tooth bar 15 that passes from housing 2 upper and lower two wall through holes vertically is being set in the sebific duct 4, add between sebific duct 4 and the two-sided tooth bar 15 and leave fit clearance, make the glue that adds in the sebific duct 4 to enter in the housing 2, it is sealed from this fit clearance.
Tooth bar 15 both sides in housing 2 are being provided with gear 3,5, two gears respectively and all are being meshed with tooth bar 15, guarantee tooth bar 15 and add between the sebific duct 4 not collision friction mutually.
One sidewall of housing 2 opens wide and cooperates side cover 10 is installed, the uniform screw hole 7 that is being provided with on housing 2 end faces that open wide, and correspondence is being provided with screw 11 on the side cover 10, with the screw 11 of screw hole 7 thread connection side cover 10 is fixedly mounted on the housing 2.Cooperate between side cover 10 and housing 2 end faces seal washer is installed, prevent that the glue in the housing 2 from leaking.Should be pointed out that the utility model housing 2 can also be arranged to roof and open wide, and the form that the sidewall sealing connects promptly is equipped with dismountable top cover on the roof that opens wide, relative set through hole and add sebific duct 4 on the top cover adopts this form of structure also to be fine.
Gear 3 is installed on the splined shaft 1, the two ends of splined shaft 1 pass from sidewall of housing 2 and end cap 10 respectively, the two ends of splined shaft 1 are installed with stabilizer 9 respectively, stabilizer 9 is sprocket wheel or gear, stabilizer 9 outsides also are being provided with locking nut 8 respectively, in order to prevent stabilizer 9 slippage from the splined shaft 1.Gear 5 is installed on the optical axis 6.When the glue between tooth bar 15 and the gear has wearing and tearing, just produce loosening between tooth bar 15 and the gear 3,5, gear 3 drives stabilizer 9 by splined shaft 1, make stabilizer 9 under loosening condition, produce inertial oscillation, the glue that adds in the sebific duct 4 is entered in the housing 2 fast produce chemical reaction, remedy loosening place with oil gas, seal once more around tooth bar 15 and the gear 3,5, thereby realize mending automatically glue work, and need not manually mend glue, increase work efficiency.
As shown in Figure 1 and Figure 2, lower wall through hole at housing 2 is outside equipped with the axle sleeve 14 that suit tooth bar 15, the bottom of axle sleeve 14 has annular lip, cooperate suit terminal pad 13 on axle sleeve 14 external surfaces of flange top, axle sleeve 14 can rotate in the through hole at terminal pad 13 centers, housing 2 can be fixedly mounted on the well mouth of oil well by terminal pad 13.
