The present application relates to a kind of oil pipe dosing device, to solve the problem of traditional dosing method medicament uniform dispersion to the bottom of oil pipe.The device includes oil pipe, adjacent oil pipe male oil pipe joint and female oil pipe joint are threadedly connected;N connection flat tubes, which are closely attached to the outer wall of the oil pipe, the n connection flat tubes are connected into a complete annular sleeve in the circumferential direction of the oil pipe, and n is an even number;Wherein, from the female oil pipe joint to the extension direction of the oil pipe body, the width of the inner cavity of the connection flat tube gradually decreases along the radial direction of the oil pipe, so that the inner cavity of the connection flat tube forms an expanded diameter structure at the connection of the upper and lower adjacent oil pipes;The connection flat tube is made of wear-resistant and corrosion-resistant composite material, and an antistatic coating is provided on the outer side wall of the connection flat tube.The present application does not need to modify the existing oil pipe structure, and the modular design improves the installation efficiency, is suitable for thick oil, high sulfur / wax oil well, can reduce the load of pumping equipment, and prolong the service life of oil pipe.

This application relates to the field of optical device technology, and discloses a Faraday rotator, its fabrication method, and an isolator. The Faraday rotator comprises multiple magneto-optical crystals and multiple heat-dissipating crystals, which are alternately stacked along the optical path. Embodiments of this application can overcome the thermal focus shift defect of the isolator without increasing the output beam diameter of the collimator.
