The invention discloses a multiphase flow hybrid conveying pipeline resistance reduction device and a multiphase flow hybrid conveying pipeline resistance reduction method of a mine field. The multiphase flow hybrid conveying pipeline resistance reduction device and the multiphase flow hybrid conveying pipeline resistance reduction method are characterized in that: hybrid conveyed fluid is accelerated by a reducing pipe and then enters a device main body pipeline by a tangential inlet pipe; and an annular space between the device main body pipeline and a hot water reflow pipe forms a rotational flow. Due to different densities, oil phase, gas phase and water phase form layered circular flows in the device main body pipeline. The water phase is closely attached to the inner wall of the device main body pipeline, so that direct contact of oil with the pipe wall is avoided, and the conveying resistance is greatly reduced. The oil phase is positioned between the gas phase and the water phase and is driven by the gas phase and the water phase to be transferred towards downstream side. One end of the oil, gas and water three-phase hybrid conveying rotational flow resistance reduction device is connected with a hot water circulating system to heat the hybrid conveyed fluid, so that on one hand, the viscosity of crude oil in the hybrid conveyed pipe can be reduced, and on the other hand, gas can be expanded properly, and the air flow speed is increased. The multiphase flow hybrid conveying pipeline resistance reduction device and the multiphase flow hybrid conveying pipeline resistance reduction method have the advantages of adoption of a physical technology for resistance reduction, no toxicity, no pollution, low manufacturing cost, reliability in operation, good resistance reduction effect, capability of effectively preventing paraffin deposit and high promotion and application value.

The invention relates to a double-trigger umbrella type oil and gas pipeline explosion-proof valve, which includes a valve body, a bracket, a valve stem guide rail, a valve stem group, an explosion-proof cover, a left mechanical response mechanism, a right mechanical response mechanism, a locking mechanism, a sensor Warm action mechanism, the two ends of the valve body are the valve diameter, the valve stem guide rail is set between the left mechanical response mechanism and the right mechanical response mechanism, the valve stem guide rail is located in the valve body, the valve stem group is surrounded by the valve stem guide rail, and the valve stem group is outsourced A layer of explosion-proof cover; the left mechanical response mechanism and the right mechanical response mechanism are installed in the center of the valve diameter at both ends of the valve body through brackets. When the pipeline burns or explodes, the limiting plate at one end of the present invention is released and moves quickly in the guide rail, so that the valve stem group shrinks rapidly, so that the valve disc presents an open posture; when the limiting plate moves to the limit distance, It is locked with another limit plate through the lock block and the lock cavity, and cannot continue to move. At this time, the valve disc is close to the inner wall of the valve body, blocking flame or shock wave, and achieving the effect of flameproofing.

Provided is a liquid discharging apparatus which includes a discharge portion which can discharge liquid, a medium support portion which can support a medium onto which the liquid is discharged, and a heating portion which can heat the medium supported by the medium support portion. The medium support portion includes a first member which can support the medium and a second member which supports the first member. Thermal diffusivity of the first member is larger than that of the second member and thermal conductivity of the second member is smaller than that of the first member.

The invention provides a coating container with selectable transportation modes. The coating container comprises a container main body, a cover body is arranged at the top of the container main body,and an auxiliary cover is further arranged on the cover body; a cavity for containing a coating is formed in the container main body, a conveying frame is detachably connected to the bottom of the container main body, a fixing frame sleeves the outer side of the container main body; reinforcing ribs are arranged between the fixing frame and the container main body, and the reinforcing rib are fixedly connected with the fixing frame and the outer side wall of the container main body correspondingly; and the fixing frame is further fixedly connected with a plurality of connecting rings, and theconnecting rings are uniformly distributed on the upper end surface of the fixing frame in a circular array by taking the geometric center line of the container main body as the axis.
