Abstract: An electromagnetic valve and an air conditioning system are provided. The electromagnetic valve includes a valve sleeve and a valve body, the valve sleeve is inserted into the valve body and fixedly connected to the valve body; a spherical sealing member is capable of moving in a valve cavity in an axis of the valve sleeve and opening or sealing a valve port, and a first connecting pipe is fixedly connected to a side wall of the valve body, the first connecting pipe is in communication with the valve cavity, and the valve body is fixedly connected to a second connecting pipe extending along an axis of the valve body, the second connecting pipe is in communication with the valve port, an axis of the first connecting pipe is flush with an end of the valve port towards the spherical sealing member, or an axis of the first connecting pipe is arranged away from the second connecting pipe relative to an end of the valve port towards the spherical sealing member.

Abstract: An electromagnetic valve and an air conditioning system are provided. The electromagnetic valve includes a valve bonnet and a valve seat. The valve bonnet includes a large-diameter section and a small-diameter section, the small-diameter section extends into a mounting groove and is affixed to a groove wall of the mounting groove, and the large-diameter section abuts against the valve seat. A first sealing surface is formed by the large-diameter section abuts against the valve seat, and a second sealing surface is formed by the small-diameter section is affixed to the groove wall of the mounting groove. The valve bonnet and the valve seat are connected in a hard sealing connection manner at the first sealing surface, and the valve bonnet and the valve seat are connected in a soft sealing connection manner at the second sealing surface.

Abstract: The present invention relates to a powder dry-pressing molding device and method.

Abstract: An alumina ceramic integrated hot press molding machine and working method thereof, including a pressing and hot pressing device fixed accordingly on a rack, a stirring device inside the hot pressing device, and a hot pressing mold above the hot pressing device; the pressing device enables one path of high-pressure air to act on the mold, and enables the other path to enter the hot pressing device, so the slurry flows into a cavity of the mold; the stirring device stirs the slurry inside the device, so alumina blanks are more evenly distributed therein; and temperature detection components for detecting the temperature of internal oil and the slurry at a slurry outlet are inside the hot pressing device, and the power of an electric heating device is adjusted and controlled in real time according to the temperature detected by the components, to achieve the purpose of accurate temperature control.

Abstract: Disclosed are a process and continuous system for producing LiPF6, and a prepared mixture crystal, composition, electrolyte solution and lithium ion battery containing LiPF6. During preparation, a first feed stream containing PF5 and a second feed stream containing LiF and HF are introduced into a first microchannel reactor, a gas part of a product in the first microchannel reactor is introduced into a second microchannel reactor to react with a third feed stream containing LiPF6, LiF and HF, and a liquid part of the product in the first microchannel reactor is subjected to crystallization and drying to obtain LiPF6. The LiPF6 has the advantages of a high purity, a uniform particle size, a high product quality stability, etc., and is suitable for use as a component of an electrolyte solution of a lithium ion battery.
