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.

And the operation process is more convenient.

The present invention belongs to the technical field of globe valves, and particularly relates to a quick-insert globe valve with a two-way shut-off function, which comprises a left valve body assembly and a right valve body assembly. The left valve body assembly includes a left valve body, a left valve core, a left cylinder sleeve, a first sealing ring and a first elastic element; the right valve body assembly includes a right valve body, a right valve core, a right cylinder sleeve, a second sealing ring and a second elastic element. When neither the first elastic element nor the second elastic element is stressed, the left valve body assembly and the right valve body assembly are sealed and not in fluid communication, and the right valve body assembly can be inserted into the left valve body assembly to connect a first flow passage chamber and a second flow passage chamber. Compared with the prior art, the beneficial effects of the present invention are as follows: (1) Two-way shut-off, flowing through when inserted and stopping flowing when pulled out, with high efficiency; (2) Can be installed in both forward and reverse directions without specifically distinguishing the direction; (3) Compact structure, good flow effect and low flow resistance; (4) Convenient for insertion and extraction. When pulled out, only need to press the anti-retreat clip to separate the left valve body assembly and the right valve body assembly.
