The utility model relates to a kind of water mixing faucet, including shell, water mixing valve and operating handle, installation sleeve around water mixing valve is fixedly connected on shell, operating handle is fixedly connected on the valve stem of water mixing valve and located above installation sleeve, installation sleeve is fixedly connected with the limiting ring located at the front side of the circular base of operating handle, limiting block is fixedly connected on the circular base of operating handle, several vertical limiting convex strips are formed on the inner wall of limiting ring, the limiting groove matched with limiting block is formed between adjacent two limiting convex strips along the circular annular array of limiting ring, when operating handle swings upward and opens water mixing valve, limiting block enters limiting groove by the lower end opening of limiting groove, when operating handle swings downward and closes water mixing valve, limiting block leaves limiting groove by the lower end opening of limiting groove.This water mixing faucet can prevent operating handle from being miscontacted and swinging horizontally when faucet is opened, maintain the stability of water temperature, and ensure good user experience.

The invention discloses a method for covering an ignition cylinder on a well mouth of an out-of-control oil and gas well, and relates to the technical field of well control emergency equipment for exploration and development operation of oil and gas fields. During operation of the ignition cylinder of a residual flange cover on the well mouth, a clamping device and a centralizing device are arranged on a rotary drilling machine in advance, and then the ignition cylinder is arranged in the clamping device and the centralizing device; the rotary drilling machine is controlled to lift the ignition cylinder, a power head of the rotary drilling machine is controlled to ascend and descend, and the height of the ignition cylinder is adjusted; the rotary drilling machine is controlled, the position of the rotary drilling machine is adjusted, and the axis of the ignition cylinder is located on the well mouth of the out-of-control well; by utilizing the self weight of the rotary drilling machine, the locking of the clamping device and the limitation of the righting device, the impact of wellhead fluid on the ignition cylinder is overcome, wellhead flames are extracted, the generation of wellhead transverse fire is reduced, the device is suitable for ignition cylinders with different sizes, the operation success rate of the ignition cylinder of a fired well cover is improved, the operation risk of rescue personnel near the wellhead is reduced, and the rescue progress of an out-of-control well is accelerated.

The invention relates to the technical field of data centers, and discloses a water supply device of an offshore data center cooling system, which comprises a pump protection pipe, a pipeline assembly and a submersible pump, the lower end of the pump protection pipe extends into seawater, the upper end of the pump protection pipe extends above an ocean platform, the pipeline assembly and the submersible pump are arranged in the pump protection pipe, and the submersible pump is fixedly connected to the lower end of the pipeline assembly. The pipeline assembly comprises a plurality of water pipe units which are connected with one another, the water pipe units can move in the axial direction of the interior of the pump protection pipe, and the water pipe units and the submersible pump can be hoisted out of or hoisted into the pump protection pipe section by section from the position above the ocean platform. Through the modular design, the pipeline assemblies can be flexibly combined according to the water depth, the water pipe units are short in length, the requirement for hoisting equipment is low, maintenance can be completed through conventional tools of the platform, divers are not needed during maintenance, all operations are conducted on the platform, and the difficulty and cost are greatly reduced.
