Abstract
The utility model discloses a kind of burner nozzle, comprise fuel(l)ing oil hose and shower nozzle, described fuel(l)ing oil hose is provided with anti-leakage mechanism near shower nozzle one end, this anti-leakage mechanism comprises valve body, valve gap and valve rod, wherein said valve body and described valve bonnet seal coordinate, described valve body center is provided with to be passed and the through hole moved around for described valve rod, and described valve body is provided with back-moving spring away between the end face of described shower nozzle and described valve stem end.Arrange anti-leakage mechanism at fuel(l)ing oil hose near the end of shower nozzle, when the burner is in operation, fuel pressure makes back-moving spring compression generation elastic force force valve gap to be opened, and fuel normally enters shower nozzle burning; During for closing burner, in fuel(l)ing oil hose, the burned device main valve of fuel cuts off, and fuel pressure declines rapidly, back-moving spring reset produces elastic force forces valve gap tightly to conform on valve body, play sealing function, interrupt the fuel supply of burner in time, complete instant action of closing burner.
Description
Technical field
The utility model belongs to firing equipment field, is specifically related to a kind of burner nozzle.
Background technology
The Furnace used in the industry such as tubular heater is petroleum refining, petrochemical industry, Coal Chemical Industry, tar production, Crude Oil Transportation.Tubular heater generally comprises radiation chamber, convection cell, burner and ventilating system, and burner generally includes nozzle, fire trough, air register and altar lamp.The nozzle that oil refining and petrochemical heating furnace burner use is nearly all internal-mixing steam atomization type, is made up of parts such as atomizing steam pipe, fuel(l)ing oil hose, atomizer, mixing chamber and shower nozzles.But run into emergency for close burner tubular heater is adjusted time, existing nozzle still has a small amount of liquid fuel after the valve of closing fuel(l)ing oil hose to be continued to flow out atomization to atomizing steam pipe, cause and immediately cannot close burner, the situation of part of fuel waste.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of burner nozzle, and it can interrupt the fuel supply of burner in time, completes instant action of closing burner.
The technical scheme that the utility model adopts is: a kind of burner nozzle, comprise fuel(l)ing oil hose and shower nozzle, described fuel(l)ing oil hose is provided with anti-leakage mechanism near shower nozzle one end, this anti-leakage mechanism comprises valve body, valve gap and valve rod, wherein said valve body and described valve bonnet seal coordinate, described valve body center is provided with to be passed and the through hole moved around for described valve rod, and described valve body is provided with back-moving spring away between the end face of described shower nozzle and described valve stem end.
As preferably, described valve body is provided with the limited post being built-in with the limit chamber passed for described valve rod away from the end face of described shower nozzle.
As preferably, between described valve body and described fuel(l)ing oil hose, be provided with sealing ring.
The beneficial effects of the utility model are: arrange anti-leakage mechanism at fuel(l)ing oil hose near the end of shower nozzle, and when the burner is in operation, fuel pressure makes back-moving spring compression generation elastic force force valve gap to be opened, and fuel normally enters shower nozzle burning; During for closing burner, in fuel(l)ing oil hose, the burned device main valve of fuel cuts off, and fuel pressure declines rapidly, back-moving spring reset produces elastic force forces valve gap tightly to conform on valve body, play sealing function, interrupt the fuel supply of burner in time, complete instant action of closing burner.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model;
Fig. 2 is the structural representation of anti-leakage mechanism.
In figure: 10, fuel(l)ing oil hose; 20, shower nozzle; 30, anti-leakage mechanism; 1, valve body; 2, valve gap; 3, valve rod; 4, back-moving spring; 5, limited post; 6, sealing ring; 11, through hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of burner nozzle, comprises fuel(l)ing oil hose 10 and shower nozzle 20, is provided with sealing ring 6 between described valve body 1 and described fuel(l)ing oil hose 10; Described fuel(l)ing oil hose 10 is provided with anti-leakage mechanism 30 near shower nozzle 20 one end, this anti-leakage mechanism 30 comprises valve body 1, valve gap 2 and valve rod 3, wherein said valve body 1 and described valve gap 2 are sealed and matched, described valve body 1 center is provided with to be passed and the through hole 11 moved around for described valve rod 3, described valve body 1 is provided with the limited post 5 being built-in with the limit chamber passed for described valve rod 3 away from the end face of described shower nozzle 20; Described valve body 1 is provided with back-moving spring 4 away between the end face of described shower nozzle 20 and described valve rod 3 end.
Arrange anti-leakage mechanism 30 at fuel(l)ing oil hose 10 near the end of shower nozzle 20, when the burner is in operation, fuel pressure makes back-moving spring 4 compression generation elastic force force valve gap 2 to be opened, and fuel normally enters shower nozzle 20 and burns; During for closing burner, in fuel(l)ing oil hose 10, the burned device main valve of fuel cuts off, and fuel pressure declines rapidly, back-moving spring 4 reset produces elastic force forces valve gap 2 tightly to conform on valve body 1, play sealing function, interrupt the fuel supply of burner in time, complete instant action of closing burner.
The above, be only the utility model preferred embodiment, therefore can not limit with this scope that the utility model implements, the equivalence namely done according to the utility model claim and description change with modify, all should still belong in scope that the utility model patent contains.
