The utility model relates to valve technical field especially is a kind of valve mounting structure with positioning function, including valve main body, flange mechanism is arranged on the valve main body and is used for installing positioning, flange mechanism includes: positioning assembly is fixed in the flange seat of the import and export end of valve main body, annular plate is rotatably installed in the inside of flange seat, the extension ear is fixed on the outer wall upper end of annular plate, the inside of annular plate is opened and is equipped with several arc grooves of circumferential distribution, the slider is slidably installed in the inside of arc groove, the flange plate is fixed in the outside of flange seat, the inside of flange plate is opened and is equipped with several circumferential distribution sliding slot, the sliding strip is slidably installed in the inside of sliding slot, and the sliding strip inner end is rotatably connected with slider, and the sliding strip outer end is fixed with bolt head;By automatic control bolt head radial adjustment, it can adapt to the flange connecting surface of different specifications within certain range, realizes fast accurate alignment with pipeline flange, improves installation efficiency.

The application provides a deepwater plug-in mistake-proof buckle water-proof casing thread joint device, which comprises a plug-in male joint and a lead-in female joint. The plug-in male joint is sequentially provided with a plug-in nose end and a female thread flank from a plug-in end to a tail. The plug-in nose end and the female thread flank are step positioning structures. The lead-in female joint is internally provided with a lead-in groove. The lead-in groove is matched with the plug-in nose end. A male thread flank is arranged on the sidewall from the lead-in groove to the inner wall tail end of the lead-in female joint. The male thread flank is correspondingly arranged with the female thread flank. The application has the beneficial effects that: the plug-in pre-connection structure can simplify the deepwater water-proof casing buckling operation process, effectively reduce the adverse effects of environmental shaking on normal buckling operation, and improve the overall operation efficiency. Meanwhile, the double-layer sealing protection formed by the stop ring and the fluorine rubber O-shaped sealing ring enables the joint to have stable high dynamic sealing performance and meet the sealing requirements under the deepwater high pressure working condition.
