The application discloses a pipe force valve with an anti-seismic protection structure, which comprises a valve body, a valve plate body, a valve rod body, a top rod shaft sleeve and a diaphragm body, the valve rod body is connected through the inside of the valve body, one side of the valve rod body is fixedly connected with the valve plate body, the upper end of the valve body is fixedly connected with the top rod shaft sleeve, and the inside of the top rod shaft sleeve is fixedly connected with the diaphragm body. The pipe force valve with the anti-seismic protection structure, when the pipe force valve body is impacted by the outside, the shell is extruded to one side of the valve body, the telescopic rod starts to contract, and the extrusion buffer air bag is extruded, at this time, the buffer air bag is buffered, when the shell moves inward, the buffer spring is compressed synchronously under the action force, and the impact force is secondarily buffered, so that the pipe force valve is less likely to be damaged under the external impact force, and the possibility of affecting the normal work of the valve is reduced.

The application provides an overcurrent detection circuit and a clothes processing device, and belongs to the field of home appliance control. A sampling module is connected with an intelligent power module, collects three-phase current signals, and obtains bus detection signals. A signal processing module is connected with the sampling module, compares the bus detection signals with reference voltage signals, obtains a comparison result signal, converts the comparison result signal, and obtains an overcurrent detection signal. The signal processing module is connected with the intelligent power module, and sends the overcurrent detection signal to the intelligent power module. The overcurrent detection is indirectly realized through the circuit, the collected three-phase current signals and the overcurrent detection signal are fully signal-isolated, the isolation between different signal ports of the intelligent power module is realized, and the problem of low overcurrent detection accuracy of the traditional circuit is solved.
