The invention relates to a safe anti-explosion gas pressure regulator. A throttling safety device is arranged at an interface position of a pressure regulating gas chamber and an inlet pipe; a safetybase of the throttling safety device is sealed and fixed on the inlet pipe; a vent hole is arranged in the safety base; a throttling safety valve core is arranged in the inlet pipe and matched with asealing surface of one opening at one end of the safety base; a reset ejecting bar penetrates through the vent hole; two ends of the reset ejecting bar are respectively matched with the throttling safety valve core and a closing plug; the closing plug is linked with one end of a hinge rod hinged on the safety base, while the other end of the hinge rod is connected with the connecting rod; and theconnecting rod penetrates through a flexible diaphragm and is connected with a reset switch outside the pressure regulator. The safe anti-explosion gas pressure regulator overcomes the defect that thecommon pressure regulator can not cut off gas source automatically when gas leaks. By adopting the specific design, the safe anti-explosion gas pressure regulator can eliminates gas safety accidentscaused by self-owned diaphragm rupture of the pressure regulator, or falling off, aging crack and rupturing by rat-bite of a gas rubber tube (hose), and the like, and the safe anti-explosion gas pressure regulator has the advantages of simple structure, high sensitivity, convenient reset operation and safe and reliable use.

The invention discloses a motor steering transmission system for a full-revolving propulsor. The motor steering transmission system comprises a steering motor bracket, transverse plates and a mountingflange, wherein two ends of the steering motor bracket are fixedly installed through matching of two sets of parallel transverse plates and the mounting flanges, the upper end surface of the transverse plate at the upper end is fixedly mounted with a steering motor, and the bottom end surface of the mounting flange at the bottom end is provided with a rotary propeller.
