Abstract
The utility model relates to an emergency device when an automatic cutting gun on the flame cutting machine has a failure during steel making and continuous casting operation; an accident cutting gun comprises a gun head, an oxygen inlet and a fuel gas inlet; the oxygen inlet is respectively communicated with a main preheating oxygen pipe and a main cutting oxygen pipe; the fuel gas inlet is communicated with a main fuel gas pipe; a cutting oxygen opening and closing valve is installed on the main cutting oxygen pipe; the gun head comprises a cutting nozzle seat, a cutting nozzle and a locking nut; and a cutting oxygen adjusting valve is further installed on the main cutting oxygen pipe. The utility model decreases the volume of the cutting nozzle seat, greatly reduces the integral weight of the cutting gun, reduces the labor, and decreases the production cost of the cutting gun; simultaneously, the cutting oxygen adjusting valve can accurately and stably control the flow rate of the cutting oxygen so that the mixing amount of gas reaches to the optimal state; and besides, the accident cutting gun can well adjust the cutting flame, thereby improving the cutting quality of steel blank.
Description
Technical field
The utility model relates to the emergency set when burning torch meets accident fault automatically on the flame cutting machine in a kind of steel-making continuous casting work, relates in particular to a kind of accident emergency burning torch.
Background technology
In steel-making continuous casting work, automatically burning torch is through regular meeting's fault that meets accident on the flame cutting machine, and the emergency set of accident burning torch when meeting accident fault is the indispensable accessory of continuous casting work.Traditional accident burning torch feeds one road oxygen and one tunnel combustion gas in use, at burning torch main body place oxygen is divided into preheat oxygen and cuts the oxygen two-way, cutting oxygen directly comes gauge tap by cutting oxygen open and close valve, preheat oxygen and combustion gas are then regulated flow by the control valve that pipeline separately is provided with, and cut oxygen, preheat oxygen and combustion gas three tunnel then and are responsible for and the welding of cutting torch seat.The cutting torch seat weight of using is all heavier at present, and the workman carries inconvenience, has increased working strength of workers, makes three the tunnel to be responsible for the intensity that also corresponding overstriking increases the weight of just can reach use simultaneously, has increased the production cost of burning torch and the weight of burning torch integral body; Cutting oxygen is responsible for by the control of cutting oxygen open and close valve, and the workman can only utilize experience to judge the flow size of cutting oxygen, can't accurately regulate the flow of cutting oxygen, the stability that can not effectively guarantee to cut oxygen flow.
The utility model content
The utility model provides a kind of accident burning torch in order to overcome the above problems, dwindled the volume of cutting torch seat, reduced the weight of burning torch integral body greatly, reduced working strength of workers, reduced the production cost of burning torch, the flow of control cutting oxygen that simultaneously can be accurate, stable makes the combined amount of gas reach preferably requirement, can well adjust cutting flame, improve the cut quality of steel billet.The utility model is simple in structure, and is easy for operation, good cutting effect.
The technical solution of the utility model is: include rifle head, oxygen inlet, fuel gas inlet, described oxygen inlet is responsible for preheat oxygen respectively and the cutting oxygen person in charge communicates, described fuel gas inlet is responsible for combustion gas and is communicated, cutting oxygen is responsible for and is provided with cutting oxygen open and close valve, described rifle head comprises cutting torch seat, cutting torch and locking nut, is responsible for also being provided with the cutting oxygen valve at cutting oxygen.
Described cutting oxygen valve includes regulates cap, valve nut, spool and sealing ring.
The utility model has the advantages that: the volume that has dwindled the cutting torch seat, reduced the weight of burning torch integral body greatly, reduced working strength of workers, reduced the production cost of burning torch, cut the flow of the control cutting oxygen that oxygen valve can be accurate, stable simultaneously, make the combined amount of gas reach preferably requirement, can well adjust cutting flame, improve the cut quality of steel billet.The utility model is simple in structure, and is easy for operation, good cutting effect.
