The invention discloses a magnetic force controlled ink permeating type micro-contact printing device, wherein a magnet sensing layer, a sealing layer, a permeating layer, a supporting layer and a cylindrical ink groove are sequentially arranged on a pattern layer. A coil sleeve is arranged on the ink groove close to one end of the support layer, an electromagnetic flow valve and an air pressure communication pipe are arranged in an ink inlet pipe at the other end, a coil on the coil sleeve is connected with a coil circuit, an elastic seal is connected with the permeating layer through a magnetic field of the coil, and a controller is respectively connected with the electromagnetic flow valve, the coil circuit and the air pressure control unit. The magnetic force controlled ink permeating type micro-contact printing device integrally controls processes of seal installation, inking and printing in a micro-contact printing process, using the magnet sensing layer as an interlayer of the elastic seal, brings convenience to installation and processing of a large-area seal, can effectively control printing parameters, fully utilizes alcohol permeability of polydimethylsiloxane, and can perform inking continuously. The air pressure control unit controls the pressure of air in the ink groove and is matched with other printing processes to limit and adjust the speed of ink permeating.

The present invention relates to an electrolyte storage unit applicable to redox flow batteries and a vanadium redox flow battery including the same. The electrolyte storage unit for redox flow batteries of the present invention can be useful in minimizing a contact area of an electrolyte with the air to improve a self-discharge phenomenon of a battery and solving a problem such as an imbalance between a concentration and a volume of the electrolyte, which is caused during battery driving. Accordingly, a cycle of a process of regenerating an electrolyte can be delayed, and capacity and lifespan characteristics of the battery can be improved. Also, the electrolyte storage unit of the present invention can be easily handled and installed because electrolytes may not be easily mixed even by external impact.

The invention discloses a mounting technology of an energy-saving heat exchange assembly, and relates to the technical field of mounting of electromechanical equipment. The mounting technology comprises the following steps: S1, a step of performing dropping treatment; S2, a step of preforming reservation of spaces; S3, a step of mounting an assembling mechanism; S4, a step of mounting an external connecting pipe; S5, a step of cleaning pipelines; and S6, a step of performing water pressure test. According to the mounting technology, an internally-built resisting spring can be driven to be deformed and also can be reset after deformation of the internally-built resisting spring is performed, so that a half-circular resisting block can be resisted and can directly move toward the interior of a circular embedding groove, and thus, assembling operations among a front clamp plate and multiple groups of internally-built heat exchanging fins can be carried out preferably; and the front clamp plate and a rear clamp plate is fixed through external fastening bolts, and a side resisting block can be directly embedded into a side resisting groove, so that fixing of a guide rod support and fixing between the rear clamp plate and the front clamp plate can be directly finished, and convenience is provided for external personnel to do mounting handling work.

The invention discloses a combined threaded perforated grid pipe. The invention relates to the technical field of grid pipes. It includes a pipe body. Hollow groove blocks are fixedly installed on the side end surfaces, side insert blocks are fixedly installed on both sides of the other end of the pipe body; a second thread corresponding groove is opened at a corner position inside the hollow groove block, Fastening bolts are rotatably connected to both sides in the middle of one end of the hollow groove block, and first thread corresponding grooves are opened at the corners of one side of the side insert block.
