在苏联和其他国家,不同结构的旋转防喷器得到实际应用。这些防喷器存在着相当大的缺点,主要是在变更钻头和钻杆尺寸时,需要将其中心部分由外壳内抽出并更换方钻杆密封环,同时这种密封环在抱紧钻具时的抱紧力不能调节,故会产生很重的磨损,特别在井内压力提高时更是如此。为了利用万能防喷器的优点,消除旋转防喷器的上述缺点,阿塞拜疆石油科学研究设计院(А_зНИПИнефть)和施密特工厂在成批生产的万能防喷器ПУГ—230×350的基础上,研制了新型的万能旋转防喷器УВП—230×210。
In the Soviet Union and other countries, rotary blowout preventers with different structures have been put into practical use. These blowout preventers present considerable disadvantages, mainly in the change of drill bit and drill pipe size, the central part of which needs to be withdrawn from the housing and replaced by the square drill rod seal ring, while the seal ring in clamping the drill Can not adjust the holding force, it will have a heavy wear and tear, especially when the pressure in the well is even more so. In order to take advantage of the universal blowout preventer and eliminate the above shortcomings of the rotary blowout preventer, the Azerbaijan Petroleum Research and Design Institute (А_НИПИнефть) and the Schmidt factory, based on the batch production of the universal blowout preventer ПУГ-230 × 350, Developed a new universal rotary blowout preventer УВП-230 × 210.
