Patent number: 7458386Abstract: The invention relates to a manual gas valve for use with either LP gas or natural gas operation with the purpose of solving the technical dilemma that the existing gas valve cannot be converted conveniently for use with different gases having different heating values. The manual gas valve of the present invention comprises a nozzle 1, a 8×1.9 O-shaped ring 2, a nozzle holder 3, a valve body 4, a faucet 5, a regulating lever 6, a 1.78×1.78 O-shaped ring 7, a spring 8, a stop plate 9, a pair of bolts 10, a mounting cover 11, and a valve stem 12. By utilizing the manual gas valve of the present invention, LP gas and natural gas can be used interchangeably and the gas flow can be conveniently regulated to achieve a similar heating value with either LP gas or natural gas operation. In addition, the conversion is easy and convenient, without requiring the use of any special tools or relying on any additional testing apparatus.Type: GrantFiled: December 30, 2006Date of Patent: December 2, 2008Assignee: Ningbo Wanan Co., Ltd.Inventor: Feng Zhang
