The invention discloses a pressure reducing valve based on a liquefied petroleum gas and natural gas dual-fuel engine. The pressure reducing valve based on the liquefied petroleum gas and natural gas dual-fuel engine comprises an upper valve cover, a lower valve cover, a rubber diaphragm, a concentrating button, an air inlet hole, an air outlet hole, a breathing hole, a spring installing hole, a filtering pad, an adjusting bolt, a flow adjusting rod, a flow adjusting lock nut, a permanent magnet ring, a spring, a closed bolt, a bolt and an adjusting device; the adjusting device comprises a vent valve opening bolt, a connecting rod, a lever, an adjusting bolt, a rubber gasket and a spring. In the manner, the pressure reducing valve based on the liquefied petroleum gas and natural gas dual-fuel engine is capable of, through the lever principle, achieving the goal of reducing the pressure and stabilizing the pressure, breaking through the constraint of the petroleum, and reaching the effect of the new energy.
Description
technical field [0001] The invention relates to the field of engine decompression valves, in particular to a decompression valve based on liquefied petroleum gas and natural gas dual-fuel engines. Background technique [0002] The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through adjustment, and relies on the energy of the medium itself to keep the outlet pressure automatically stable, that is, by changing the throttling area, the flow rate and the kinetic energy of the fluid are changed. Different pressure losses are caused to achieve the purpose of decompression, and then rely on the adjustment of the control and regulation system to balance the pressure fluctuations with the spring force, and the pressure remains constant within a certain error range. [0003] Pressure reducing valves are often used in the field of equipment such as engines. However, the technology of pressure reducing valves applied to dual-f...
