5results about How to "Control supply" patented technology

The invention relates to the technical field of gas alarms, in particular to a combustible gas monitoring valve automatic disconnecting device which comprises a pressure regulating assembly, an emergency cut-off valve, a main gas feeding pipeline, a control valve, a three-way pipe, an emergency cut-off assembly, a monitoring assembly and a one-way ventilation pipe. The change of the surrounding environment is detected by monitoring the light intensity change in the optical fiber conveying process, so that trace combustible gas in the environment can be detected in an extremely short time, an alarm and an automatic valve breaking action are quickly triggered, in addition, the structure of combining an automatic control system and a manual control system is adopted, and the safety of the system is improved. And the gas supply can be safely and effectively controlled under any condition.

This disclosure provides a method for controlling carbon dioxide concentration, a carbon dioxide solution generating device, and related equipment, relating to the field of electrical control technology. The carbon dioxide solution generating device is used to provide a carbon dioxide solution containing carbon dioxide gas and water. The carbon dioxide concentration control method is used to control the carbon dioxide concentration of the carbon dioxide solution provided by the carbon dioxide solution generating device. It collects the actual gas pressure of the carbon dioxide gas, the actual temperature of the water, and the actual volume concentration of carbon dioxide in the carbon dioxide solution formed by mixing the carbon dioxide gas and water. Based on these parameters, the carbon dioxide supply of the carbon dioxide solution generating device is controlled. This disclosure enables more precise control of the carbon dioxide concentration in the carbon dioxide solution provided by the carbon dioxide solution generating device.

The present invention provides a resin material supply device, a resin molding device, and a method for manufacturing a resin molded product that can control the supply amount of resin material with high precision. The resin material supply device includes: a resin material supply unit that supplies resin material; a first resin material conveying unit that supplies resin material from the resin material supply unit; a second resin material conveying unit that conveys the resin material conveyed by the first resin material conveying unit to a molding die; and a control unit that adjusts the supply amount of resin material from the resin material supply unit at a certain time based on the supply amount of resin material from the resin material supply unit at a time before the certain time when the resin material supplied to one of the second resin material conveying units is divided into multiple times and supplied from the resin material supply unit to the first resin material conveying unit.

This invention belongs to the field of reactor technology and discloses an olefin polymerization reactor with a discharge port at the bottom. It includes: a stirring device, a gas distribution device, a feeding system, an internal cooling system for heat removal, and an external circulation system for heat removal located outside the reactor. The stirring device extends into the reactor. The feeding system consists of a feed pipe installed from the top to the bottom of the reactor. The gas distribution device consists of an inlet pipe installed from the top to the bottom of the reactor. The internal cooling system is located around the gas distribution device. The external circulation system is a jacket located outside the reactor. The feed pipe and the inlet pipe are detachable. This invention effectively solves the problem of material agglomeration and reduced reaction rate caused by the inability to quickly remove heat during the reaction due to exothermic reactions. It enhances heat exchange, improves reaction efficiency, stabilizes production, and significantly reduces maintenance costs.

The application discloses a rotating hook oil supply control device and a sewing machine, and belongs to the technical field of sewing devices. The application discloses a rotating hook oil supply control device, which comprises a rotating hook, a lower shaft, a pump shaft sleeve, an electric three-way valve and an oil path switch control assembly. The pump shaft sleeve is provided with a rotating hook oil supply channel and a lower shaft mounting channel. The lower shaft is arranged in the lower shaft mounting channel. The rotating hook oil supply channel is communicated with the rotating hook through the lower shaft mounting channel. The electric three-way valve is communicated with two oil inlets through two oil supply pipes. The oil path switch control assembly is used for controlling the opening and closing state and the opening degree of the pipeline flowing to the rotating hook. The application discloses a rotating hook oil supply control device and a sewing machine. The electric three-way valve can automatically control the opening and closing state of the two oil supply pipes, so as to determine whether to deliver lubricating oil to the rotating hook oil supply channel and the lower shaft mounting channel through the oil inlets. The problem that the rotating hook and the main shaft are bound to the oil amount in the existing oil supply device is solved.
