A hydraulic one-way cut-off quick cartridge valve comprises a valve body and a valve element assembly, a mounting cavity is formed in the valve body, and a first opening and a second opening are formed in the side wall of the mounting cavity; the valve element assembly is installed in the installation cavity and comprises a first valve head and a second valve head which are connected in a sliding mode, a supporting spring is arranged between the first valve head and the second valve head so that the first valve head can abut against the first opening, and the second opening is formed between the first valve head and the second valve head. The on-off state of the cartridge valve is changed by controlling the valve element assembly to achieve the communication state of the first opening and the second opening, so that the oil inlet valve has the function of a high-pressure isolation valve, the structure of an injection oil way is simplified, and the cost of the oil way is reduced.

The invention provides a high-precision laser welding temperature measurement optical device and system, and the device comprises a welding mechanism which comprises a laser transmission joint, a light path transmission lens and a dual-band achromatic field lens, and the light path transmission lens is disposed between the laser transmission joint and the dual-band achromatic field lens; and the temperature detection mechanism comprises a temperature measurement sensor and a temperature signal processor, and the temperature measurement sensor is in signal connection with the temperature signal processor. According to the laser welding device, laser welding machining is conducted on the to-be-welded element through the welding mechanism, effective overlapping and synchronous follow-up of double light spots can be guaranteed through the double-waveband achromatic field lens, and therefore the purpose of guaranteeing the consistency and quality stability of the welding process is achieved. In the process, the temperature detection mechanism can analyze and monitor the welding heat according to the feedback laser, and compared with existing conventional laser welding equipment, the laser welding equipment has the advantages of being high in welding quality, capable of achieving real-time monitoring, accurate in temperature detection, high in effect speed, wide in application range and the like.
