This invention provides a frequency-to-analog safety barrier, comprising a voltage conversion circuit, a transformer coil drive circuit, a transformer, a first AC voltage rectification and filtering circuit, a frequency signal processing circuit, a NAMUR signal processing circuit, an NPNPNP signal processing circuit, a frequency processing circuit, an MCU control circuit, a TTL output interface, an isolation chip, a square wave processing circuit, a filtering circuit, a DC output circuit, and an alarm relay. The voltage conversion circuit is connected to the transformer via the transformer coil drive circuit. The transformer supplies power to the hazardous and safe zones via the first AC voltage rectification and filtering circuit. Multiple intrinsically safe terminals in the hazardous zone are connected to the frequency processing circuit via three signal processing circuits. The frequency processing circuit outputs to the MCU control circuit. The MCU output sequentially passes through the TTL interface, the isolation chip, the square wave processing circuit, and the filtering circuit to the DC output circuit. This invention achieves frequency signal to analog quantity conversion and safety isolation, increasing system stability.

This utility model discloses a DTNF membrane module, relating to the field of filtration membrane module technology. It includes a base, with a convenient disassembly and assembly mechanism on the top of the base, and a coarse filter protection mechanism on the mechanism. The convenient disassembly and assembly mechanism includes a first side plate and a second side plate. The second side plate is fixedly installed on the top of the base, and a support column is fixedly installed on the left side of the second side plate. Through the overall design of the convenient disassembly and assembly mechanism, this utility model allows for easy disassembly and maintenance of the filter cartridge. Pushing the sleeve to the right from the handle causes the filter cartridge to move out of the sleeve, and then pulling the fitting tube out of the protruding tube, thus disassembling the filter cartridge. Conversely, pushing the sleeve to the right first, inserting the fitting tube into the protruding tube, and then releasing the sleeve allows the elastic element to push the sleeve into the right end of the filter cartridge, completing the installation. The disassembly and assembly process is simple and efficient.

This utility model belongs to the field of air conditioning technology and discloses an easy-to-install air conditioning duct, including a duct flange one. A handle is fixedly installed inside the right side of the duct flange one. A lead screw is rotatably installed on the rear side of the handle. A nut is screwed onto the outside of the lead screw. A second duct flange is fixedly installed outside the nut. This utility model connects the handle on the right side of the duct flange one to the lead screw, and the nut on the outside of the lead screw connects to the second duct flange. When the handle is rotated, the lead screw rotates, causing the nut to move along the lead screw, thereby moving the second duct flange. During installation, workers only need to operate the handle to easily adjust the distance between the two duct flanges, eliminating the need for complex tools and a large amount of manpower for forced connection, greatly improving installation efficiency. Especially in narrow or high spaces where operation is difficult, this adjustment method makes installation work easy and simple.
