Abstract

A one-way valve for general small-sized gasoline engine vent gas purification includes a housing that has an air inlet hole (11) and an air outlet hole (21), a reed (7) that has a fixed end (73) and a free end (72), and a baffle (8) arranged in the back of the reed (7), the housing comprises an upper housing (1) with the air inlet hole (11) and a lower housing with the air outlet hole (21), a body (6) is arranged in the inner cavity of the housing, the reed (7) closes to the air outlet (21) and is covered on the air inlet (61), the fixed end (73) of the reed (7) is connected to the body (6), on end of the baffle (8) closes to the fixed end (73) of the reed (7) and is arranged on the body (6), the other end is opened along the direction of free end (72) of the reed (7). Compared to the prior art, the invention has advantages of simple installation, strong general purpose, good stability.

Description

technical field [0001] The invention relates to a one-way valve, in particular to a one-way valve for purifying tail gas of a general small gasoline engine. Background technique [0002] General-purpose small gasoline engine is referred to as general-purpose engine, which refers to a small gasoline engine not exceeding 19KW for non-road use, and is often used in generators, water pumps, lawn mowers, chain saws, cutting machines, etc. [0003] With the widespread use of general-purpose small gasoline engines, the tail gas emitted by them has become one of the main sources of air pollution. The research results of the United States and the European Union show that: with the increasingly effective emission control of road vehicles, the emission of non-road engines, which was originally a secondary position and received less attention, has become the main source of pollution. According to the US EPA, the total emissions of road vehicles and non-road power machinery in 2000: ...
