Title
(EN) GAS DISTRIBUTION DEVICE AND COMBUSTOR HAVING SAME, AND WATER HEATER
(FR) DISPOSITIF DE DISTRIBUTION DE GAZ, CHAMBRE DE COMBUSTION COMPRENANT CE DERNIER, ET CHAUFFE-EAU
(ZH) 分气装置及具有其的燃烧器和热水器
Abstract
(EN) A gas distribution device (100) and a combustor having same, and a water heater. The gas distribution device (100) comprises multiple gas distribution pipes (1), the gas distribution pipes (1) being parallel to each other and arranged at intervals, and each of the gas distribution pipes (1) being provided with multiple gas nozzles (2); and at least one gas delivery pipe (3) communicated with the gas distribution pipes (1) to connect the gas distribution pipes (1) as an integrated structure, the gas delivery pipe (3) being used for supplying gas to the gas distribution pipes (1), the gas delivery pipe (3) being provided with a gas delivery interface (4), and the gas delivery interface (4) being used for connecting a gas inlet valve. Since the gas distribution device (100) is communicated with the gas distribution pipes (1) by means of the gas delivery pipe (3), and the gas delivery pipe (3) is integrally connected to the gas distribution pipes (1), the gas delivery pipe (3) can synchronously deliver the same amount of gas to the gas distribution pipes (1), so that the gas content in each gas distribution pipe (1) is well-distributed, thereby enabling a flame spurting out from the gas distribution device (100) to be more stable.
(FR) L'invention porte sur un dispositif de distribution de gaz (100), sur une chambre de combustion comprenant ce dernier, et sur un chauffe-eau. Le dispositif de distribution de gaz (100) comprend : de multiples tuyaux de distribution de gaz (1) qui sont parallèles les uns aux autres et disposés suivant certains intervalles, et qui sont chacun pourvus de multiples buses à gaz (2); et au moins un tuyau d'alimentation en gaz (3) en communication avec les tuyaux de distribution de gaz (1) de manière à relier ces derniers sous la forme d'une structure intégrée, le tuyau d'alimentation en gaz (3) servant à alimenter en gaz les tuyaux de distribution de gaz (1), et étant pourvu d'une interface d'alimentation en gaz (4), et l'interface d'alimentation en gaz (4) servant au raccordement d'un clapet d'admission. Étant donné que le dispositif de distribution de gaz (100) est en communication avec les tuyaux de distribution de gaz (1) au moyen du tuyau d'alimentation en gaz (3), et le tuyau d'alimentation en gaz (3) est relié d'un seul tenant aux tuyaux de distribution de gaz (1), le tuyau d'alimentation en gaz (3) peut délivrer de manière synchrone la même quantité de gaz aux tuyaux de distribution de gaz (1), de telle sorte que la teneur en gaz dans chaque tuyau de distribution de gaz (1) est bien répartie, ce qui permet à une flamme sortant du dispositif de distribution de gaz (100) d'être plus stable.
(ZH) 一种分气装置(100)及具有其的燃烧器和热水器,分气装置(100)包括多个分气管(1),各分气管(1)相互平行且间隔设置,每一分气管(1)上设置多个气嘴(2);至少一个输气管(3),与各分气管(1)连通,将各分气管(1)连接为一体式结构,输气管(3)用于向各分气管(1)内供气;输气管(3)上设置有输气接口(4),输气接口(4)用于连接进气阀门。该分气装置(100)由于通过输气管(3)连通了各分气管(1),且输气管(3)与各分气管(1)一体连接,因此能够实现输气管(3)同步向各分气管(1)中等量输送气体,使得各分气管(1)中的气体含量均匀,从而使得分气装置(100)喷出的火焰更加稳定。
