Multifunctional valve

Номер: CN104948787A
Автор: RUAN WANSHENG
Принадлежит:

The invention belongs to the technical field of machinery, and provides a multifunctional valve which solves the problems that an existing multifunctional combination valve is high in cost and not convenient to operate. The multifunctional valve comprises a valve body with the two ends being a water inlet end and a water outlet end respectively, a filter pipe is arranged on the outer side of the valve body, a filter screen is arranged in the filter pipe, and a pressing cap is connected to the outer end of the filter pipe in a threaded mode. A first mounting pipe and a second mounting pipe are further arranged on the outer side of the valve body, and the first mounting pipe and the filter pipe share the same axis. A first water hole is formed in the valve body and located between the filter pipe and the first mounting pipe, and a second water hole is formed in the valve body and located between the filter pipe and the second mounting pipe. A first plug and a first spring are arranged in ...

Preparation and application of manganese-doped MoS2 electrocatalyst

Номер: CN116445959A
Автор: TENG FEI, RUAN WANSHENG, MA BEN
Принадлежит:

The invention discloses a preparation method and application of a manganese-doped MoS2 electrocatalyst, and belongs to the technical field of electrocatalytic hydrogen production, and the preparation method comprises the following steps: adding ammonium molybdate, manganese chloride and potassium thiocyanate into a container, uniformly stirring, heating, cooling, dissolving KSCN in distilled water, collecting a product, and washing to obtain the manganese-doped MoS2 electrocatalyst. The manganese-doped MoS2 is used as an electrocatalyst material, and has outstanding performance in the aspect of electrocatalytic hydrogen production: when the voltage reaches 10mAcm <-2 >, the required overpotential is only 79mV; the Tafel slope of hydrogen production is only 55.46 mV/dec, and the result is superior to that of most reported MoS2-based hydrogen production electrocatalysts.
