The invention relates to a high-pressure natural gas reducing valve which comprises a valve cover, a valve body, a pressure sensing diaphragm, a pressure preset mechanism and a valve-plug mechanism, wherein the valve-plug mechanism comprises a gas-valve connection block in which a valve port and an airflow channel are arranged and a valve clack assembly consisting of a valve-clack rod and a valve-clack ejector rod; the top of the valve-clack rod is provided with a circumferential boss, and the surface of the circumferential boss is provided with a sealing gasket; the valve-clack ejector rod passes through the valve port and is in overlap joint with the pressure sensing diaphragm; the lower part of the valve body is provided with a valve-clack groove, and a valve-clack spring is arranged between the circumferential boss of the valve-clack rod and a rabbet end face of the valve-clack groove; and a cavity is arranged in the valve clack assembly, the valve port is in the shape of cone, and the diameter of the valve port is same as that of the valve-clack rod. The high-pressure natural gas reducing valve has the advantages that because the reducing valve adopts the structure above, the axial pressure of the valve clack assembly is balanced, the pressures on the upper and lower surfaces of the valve clack assembly of the reducing valve are not affected by the pressures on a user side and a storage tank side, thereby eliminating the influence on the outlet pressure of a pressure reducing/adjusting valve when the operating pressure on the storage tank side is changed, avoiding that the valve port always produces pressures on the sealing gasket by the retraction pressure of the pressure sensing diaphragm, and prolonging the service life of the sealing gasket.

A drag reduction method and apparatus for reducing aerodynamic pressure drag associated with a vehicle in motion by use of grit, grit tape, or other turbulator to increase the momentum of boundary layer flow over a vehicle. A turbulator, such as grit tape, can be attached to the smooth external body surface of the vehicle to improve upon a vehicles fuel economy. The turbulator associated with the grit material reduce the effects of the pressure drag by creating a turbulent boundary layer over the surface of the vehicle that moves a separation point from a laminar flow to a turbulent flow backwards along the vehicle. The reduction in pressure drag reduces the overall energy needed to move the vehicle through the air, which improves upon the fuel economy of the vehicle.
