The present invention provides an automatic stop device that simplifies the structure, improves the responsiveness and reliability of stopping fluid delivery, and enables rapid stopping of fluid delivery in emergencies, as well as a siphon-type fluid delivery pump equipped with this automatic stop device. [Solution] The device includes a float 212 that detects the liquid level in the container to which the liquid is being delivered, and a storage section 213 that houses the float and holds air. A communication hole 214 is opened at the top of the storage section, and the held air is sent to the discharge valve 14 of the pump 1 via an air inlet tube 215. A slide valve 211 that operates in response to the float rising connects the top of the storage section and the air inlet tube via the communication hole when the float rises to a predetermined position. As a result, the discharge valve is closed by the released air, the liquid flow in the discharge hose 15 is restricted, and the liquid delivery of the siphon-type liquid delivery pump is stopped. This provides an automatic stop device 2 and a siphon-type liquid delivery pump having an automatic stop device.

The application discloses a kind of method and device that SSD control chip self-adapting abnormal stop IO, it is related to SSD technical field, comprising: obtaining the fatal error interrupt signal generated by multiple function modules in SSD control chip, global stop flow enable signal is generated by hardware logic circuit;In response to this signal, synchronously control host interface side stops transmitting data to host, and control flash interface side stops reading and writing NAND flash to erase operation.By pure hardware circuit, the fast convergence of error signal and the generation of global stop flow instruction are realized, the extremely fast response of nanosecond to microsecond level is achieved, and the defect of large delay of software dependent scheme is fundamentally overcome.Two ends stop flow are triggered synchronously using single enable signal, the atomicity and cooperativity of operation are ensured, and the risk of data inconsistency is eliminated.The mechanism is independent of central processing unit and firmware operation, and can still be independently and reliably executed in the extreme case of core component failure, significantly improving the data integrity and system reliability of SSD.

The utility model provides building engineering repairing and caulking equipment, which belongs to the technical field of building engineering, and comprises a bottom frame, universal wheels mounted at four corners of the bottom end of the bottom frame, a push handle fixed on one side of the top end of the bottom frame, and a control box mounted at the top end of the push handle, the cleaning structure comprises a top frame fixed to the top end of the interior of the tank body, a scraper fixed to the bottom end of the connecting rod and a reinforcing ring fixed to the interior of the scraper, and the flow stopping structure is arranged on the outer side of the grouting pipe. According to the device, the stirring rod drives the main gear to rotate, so that the lower shell drives the scraper to rotate on the inner wall of the tank body, the inner wall cleaning function of the device is achieved, impurities such as mortar and a joint mixture attached to the inner wall of the tank body are effectively removed, and workers can conveniently clean and maintain the device subsequently; meanwhile, the materials can be better and uniformly mixed, and the performance of the joint filling material is improved.

This invention relates to an axial flow high-frequency solenoid valve, comprising an outlet valve body, a valve core assembly, a housing, a coil, a coil frame, and an upper stop. The upper stop includes a housing connecting portion and a stop portion. A stop flow channel is provided within the upper stop, distributed within the housing connecting portion and the stop portion. The coil is wound around the outside of the coil frame, which is fitted over the outside of the stop portion. An outlet flow channel is provided within the outlet valve body, and a valve seat is provided at the input port of the outlet flow channel. The housing includes a main housing portion, which is fitted over the outside of the coil frame. One end of the main housing portion is sealed to the housing connecting portion, and the other end is sealed to the outlet valve body. The outlet flow channel communicates with the stop flow channel. The valve core assembly is located within the main housing portion and between the outlet valve body and the stop portion. The control coil is energized or de-energized to control the valve core assembly to open or close the outlet flow channel. The overall structure is compact and easy to install.
