Abstract
The utility model discloses a kind of petroleum sleeve joint, relate to oil recovery technique field, comprise case, axle sleeve, bearing, motor, spring, large airtight pane, little airtight pane, moving lever and flange; Described flange is two, is integrally formed in case lower end by the mode of left and right symmetry; Described bearing is fixedly connected on the upper surface of case by axle sleeve; Described moving lever runs through bearing and case, and on described moving lever, centre position arranges large airtight pane, and described moving lever lower end is fixedly connected with little airtight pane; The power shaft of described moving lever is connected with the output shaft axle of motor; Be provided with a spring between described case and large airtight pane, described spring is coated on the outer round surface of moving lever.Its reasonable in design, modern design is unique, simple to operate, easy to use, variable-frequency motor is set and namely can facilitates speed governing, also can automatically close, save manual operation, adopt disk spring can play the effect of damping, and the disk spring life-span is long, double density shrouding is set, effectively can plays sealing function.
Description
Technical field:
The utility model relates to oil recovery technique field, is specifically related to a kind of petroleum sleeve joint.
Background technology:
At present, along with the development of China's oil industry, so union can not be ignored, union must can keep sealing under the enough condition of intensity under vibration, compression shock.Pouring into external leakage at height to putting, not allowing air inwardly to infiltrate having in negative pressure line, the casing joint used at present, under the effect of vibrations pressure, causes sealing bad, occurs leakage problem.
Utility model content:
In order to solve the problem, the utility model provides a kind of technical scheme: a kind of petroleum sleeve joint, comprises case, axle sleeve, bearing, motor, spring, large airtight pane, little airtight pane, moving lever and flange; Described flange is two, is integrally formed in case lower end by the mode of left and right symmetry; Described bearing is fixedly connected on the upper surface of case by axle sleeve; Described moving lever runs through bearing and case, and on described moving lever, centre position arranges large airtight pane, and described moving lever lower end is fixedly connected with little airtight pane; The power shaft of described moving lever is connected with the output shaft axle of motor; Be provided with a spring between described case and large airtight pane, described spring is coated on the outer round surface of moving lever.
As preferably, described motor is variable-frequency motor.
As preferably, described spring is disk spring.
As preferably, described bearing, large airtight pane and little airtight pane are rectangular plate.
The beneficial effects of the utility model: its reasonable in design, modern design is unique, simple to operate, easy to use, variable-frequency motor is set and namely can facilitates speed governing, also can automatically close, save manual operation, adopt disk spring can play the effect of damping, and the disk spring life-span is long, double density shrouding is set, effectively can plays sealing function.
