Abstract
The utility model discloses a nozzle of a burner of a water heater. The middle part of the nozzle is provided with a via hole. The front segment of the via hole at the middle part of the nozzle is a cylinder with the length of 1 mm, and the back segment with the length of 10 mm is conical. The hole diameter of the front end of the nozzle is phi 0.6 to phi 1.35 mm, and the hole diameter of the back end of the nozzle is phi 3.7 to phi 3.9 mm. Because the nozzle of the utility model has the geometric size and the shape, the nozzle has the abilities of reducing the primary air coefficient and increasing the secondary air coefficient, and the burning device of a water heater has the function of low combustion noise.
Description
Technical field
The utility model relates to water heater, especially a kind of water heater burner nozzle.
Background technology
At present, the used burner of the quick formula water heater of combustion gas descends in working order, combustion gas sprays the injection primary air through tracheae by nozzle, and then carry out auxiliary air at burner burner place and mix, last combustion gas is burnt at jet-burner, because the primary air ratio height that present burner nozzle length weak point and its physical dimension and shape make the quick formula water heater of combustion gas, burning auxiliary air coefficient is low, flame is short, thereby the combustion noise that makes burner is than higher, at above-mentioned situation, designed a kind of low burner nozzle of burner combustion noise that makes.
Summary of the invention
The purpose of this utility model provides a kind of low water heater burner nozzle of water heater combustion noise that makes.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of water heater burner nozzle, and the nozzle middle part is a through hole, and nozzle middle part through hole leading portion is cylindrical, and this segment length is 1mm; Back segment is conical, and this segment length is 10mm; The spray nozzle front end aperture is Φ 0.6-Φ 1.35 mm, and aperture, nozzle rear end is Φ 3.7-φ 3.9mm.
The front end of described nozzle is a taper seat, and the rear end of nozzle is a screw thread, between the taper seat of nozzle and screw thread two sections faces of cylinder is arranged, and between two sections faces of cylinder step is arranged; The front end of nozzle is 7.4-7.6mm to the distance of the initial end of thread segment.
The axial horizontal length of the taper seat of described nozzle is 1mm, and the axial horizontal length of roundlet cylinder is 1.5mm, and the axial horizontal length of hexagonal prism face is 3mm.
The utility model nozzle middle part through hole leading portion is cylindrical, and this segment length is 1mm; Back segment is conical, and this segment length is 10mm; The spray nozzle front end aperture is Φ 0.6-Φ 1.35mm, and aperture, nozzle rear end is Φ 3.7-Φ 3.9mm.The axial horizontal length of the taper seat of described nozzle is 1mm, and the axial horizontal length of roundlet cylinder is 1.5mm, and the axial horizontal length of hexagonal prism face is 3mm.Because the utility model nozzle has above-mentioned physical dimension and shape, thereby has determined it to have the minimizing primary air ratio, increase the ability of auxiliary air coefficient, thereby make the water heater burner have the low function of combustion noise.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The structure of the utility model water heater burner nozzle is seen shown in Figure 1: the nozzle middle part is through hole, and nozzle middle part through hole leading portion is cylindrical, and this segment length is 1mm; Back segment is conical, and this segment length is 10mm; The spray nozzle front end aperture is Φ 0.6-Φ 1.35mm, and aperture, nozzle rear end is Φ 3.7-Φ 3.9mm.The front end of described nozzle is taper seat a, and the rear end of nozzle is screw thread b, between the taper seat a of nozzle and screw thread b two sections face of cylinder c, d is arranged, and between two sections faces of cylinder step e is arranged; The front end of nozzle is 7.4-7.6mm to the distance of the initial end of thread segment.The axial horizontal length of taper seat a of described nozzle is 1mm, and the axial horizontal length of roundlet cylinder c is 1.5mm, and the axial horizontal length of hexagonal prism face d is 3mm.The utility model is following in working order, and gas-flow is sprayed by nozzle through foundry goods tracheae, section bar tracheae, the injection primary air, and after burner burner place carried out the auxiliary air mixing, combustion gas was burnt at jet-burner again.This burner has lower combustion noise, is because shape, the size of nozzle and burner burner have determined it to reduce primary air ratio, increases the ability of auxiliary air coefficient.
