Abrégé

The present application relates to the technical field of gas water heaters, and in particular to a burner row and a burner. Gas channels and air channels that are not in communication with each other are arranged alternately in the direction of width inside the burner row, and an air channel is arranged on either side of each gas channel; an air output hole in communication with and corresponding to each air channel is provided at the top end of the burner row, and a plurality of fire holes corresponding to each gas channel are provided at the top end of the burner row in the direction of length; and two adjacent fire holes are arranged in a staggered manner in the direction of length of the burner row. Gas ejected from the fire holes mixes crosswise with air flowing out of the air output holes on two sides. In addition, the plurality of fire holes are arranged in a staggered manner in the direction of length, so that the contact area between the gas and the air at the fire holes is further increased, improving a mixing effect of the gas and the air, and reducing the combustion time of the gas, and thus improving the combustion efficiency and combustion stability.

Abrégé

The present application relates to the technical field of gas water heaters, and in particular relates to a burner row and a burner device. Gas channels and air channels not in communication with each other are arranged inside the burner row side by side along a width direction, one air channel being provided between every two adjacent gas channels. Burner holes corresponding to each gas channel and in communication with the gas channels are disposed on a top end of the burner row, air outlet holes corresponding to each air channel and in communication with the air channels are disposed on the top end of the burner row, and the burner holes and the air outlet holes are arranged so as to be staggered along the width direction. The burner device comprises the burner row; gas at the burner holes and air flowing out of the air outlet holes intersect and mix, thereby improving the mixing effect of the gas and the air. A supplementary channel for supplying air is formed between adjacent burner rows, thereby further improving the mixing effect of the gas and the air, minimizing load concentration, and preventing a localized high-temperature burning region. The present invention decreases combustion time of a gas, improving burning efficiency and burning stability, and also prevents the issue of deflagration or detonation caused by flashback.

The present application relates to a vehicle-mounted water heater. During installation, a combustion heat-exchange assembly is provided on the side of an installation chamber away from an opening, and a fan assembly is installed on the side of the installation chamber close to the opening, such that generated high-temperature flue gas can be pumped out by the fan assembly via a flue gas outlet channel, thus helping to heat a water source; a clearance space communicated with the opening is formed between a support frame and one side wall of the installation chamber; a sampling interface is integrally provided on a valve body and the sampling interface is arranged facing the opening, thus facilitating operators in connecting sampling interfaces and sampling tubes in installation chambers, and reducing the difficulty for operators in installing valve bodies and adapted elements of the valve bodies. During connection of a sampling interface and a sampling tube, the processes of complete machine assembly can be reduced for the vehicle-mounted water heater, facilitating complete machine installation, and reducing the difficulty and costs of the part production process.

Abrégé

A water-gas linkage valve includes a water valve body assembly (1) with a high pressure water chamber (121), a gas valve body assembly (2), a linkage assembly (3) for connecting the gas valve assembly (2) with the water valve body assembly (1), and a low pressure water chamber (122). A gas outlet (32) is provided in the linkage assembly (3). The low pressure water chamber (122) is connected with the high pressure water chamber (121) by a venturitube (13). The low pressure water chamber (122) is provided in the water valve body assembly (1). A pressure transmission unit is formed when the water valve body assembly (1) is connected with the linkage assembly (3). The pressure transmission unit is isolated from the high pressure water chamber (121) and the low pressure water chamber (122) by a diaphragm (131,132). The linkage assembly (3) is controlled by the water valve body assembly (1) based on the change of the pressure difference between the high pressure water chamber (121) and the low pressure water chamber (122), and then the linkage assembly (3) controls the open and close of the gas in the gas valve body assembly (2). Since the high and low pressure water chambers (121,122) are isolated from the linkage assembly (3) by the diaphragm (131,132), it avoids the water directly touching with the metal parts of the linkage assembly and effectively prevents sediment incrustation and corrosion.
