The application discloses a gas-water diversion anti-siphon device, which comprises a water storage tank body, a water inlet pipe joint, a water outlet pressure-limiting backflow valve assembly, a pressure-loss air inlet valve assembly and a pressure-loss water outlet valve assembly. The water inlet pipe joint is arranged at the upper half of the water storage tank body and is connected with a water supply pipe network. The water outlet pressure-limiting backflow valve assembly is arranged at the lower half of the water storage tank body and is connected with downstream water using appliances. The pressure-loss air inlet valve assembly and the pressure-loss water outlet valve assembly are arranged at the top end and the bottom end of the water storage tank body, respectively. When the water supply pipe network is shut down and negative pressure is generated, the pressure-loss air inlet valve assembly is opened to enable air to enter the water storage tank body and flow into the water supply pipe network through the water inlet pipe joint. Meanwhile, the pressure-loss water outlet valve assembly is opened to discharge the accumulated water in the water storage tank body. Meanwhile, the water outlet pressure-limiting backflow valve assembly is closed to prevent downstream water from flowing back into the water storage tank body.

The utility model provides a waste calcium carbide remelting and upgrading conveying device, which belongs to the technical field of conveying devices, and comprises a crushing chamber, a rotator arranged in the crushing chamber, two first rotating shafts rotationally connected in the rotator, two crushers fixedly connected to the lower ends of the two first rotating shafts, and two second rotating shafts rotationally connected in the two crushers. The two first gears are fixedly connected to the circumferential surfaces of the two first rotating shafts, the gear ring is fixedly connected to the interior of the crushing chamber, and the first gears are meshed with the gear ring. Meanwhile, powder calcium carbide directly reaches the furnace bottom through the inside of the electrode and does not make contact with a furnace charge layer, current shunting is eradicated, waste products are directly added to the furnace bottom after being powdered and can be rapidly reacted and fused with semi-finished product calcium carbide, and electric energy consumption is greatly reduced.

The utility model discloses a projection welding electrode assembly for preventing molded surface interference during nut projection welding of an L-shaped part, which relates to the technical field of projection welding electrode assemblies and comprises a projection welding machine, an upper electrode arm is fixedly connected to the upper side of the left side wall of the projection welding machine, and an upper electrode holding rod is fixedly connected to the lower side of the outer side wall of the upper electrode arm. The projection welding electrode assembly comprises an upper electrode holding rod, the bottom end of the upper electrode holding rod is fixedly connected with an upper electrode assembly, the two sides of the outer side wall of the upper electrode assembly are fixedly connected with water pipe connectors, and the bottom end of the upper electrode assembly is fixedly connected with a projection welding upper electrode. The clamping pin can be rapidly replaced according to the size of a positioning hole of a part, the replaced clamping pin can stably fix the part, the part and the upper electrode can be separated through the buffer insulating plate, the upper electrode is protected, and the situation that the upper electrode makes contact with an iron material, and consequently electricity conduction occurs, and shunting is generated is prevented.

This invention relates to the field of automotive manufacturing technology and provides an adjustable positioning mechanism for automated welding of automotive parts. The mechanism includes a fixed base, a first support rod, a second support rod, and an electrode assembly. The fixed base has a vertically mounted first and second support rods that can slide up and down relative to it. A first magnet and a second magnet are fixedly connected to the first and second support rods, respectively. The electrode assembly is mounted on the fixed base via an insulating sleeve. The electrode assembly includes an electrode, an electrode fixing base, and a lower electrode arm connected in sequence. The top of the electrode extends upward to form a positioning post for mounting the workpiece. Springs are mounted on the first and second support rods. The lower end of the spring abuts against the fixed base, and the upper end abuts against the bottom of the first or second magnet, allowing the magnet to slide with the support rod and compress the spring. This invention solves the problems of workpiece rotation and unreliable clamping in traditional positioning mechanisms.
