Abstract
The utility model provides a novel carbon dioxide welding and gas cutting flowmeter for a central gas supply system, which comprises a flowmeter main body and a connecting piece. The flowmeter main body comprises a housing, and a gas inlet and a gas outlet which are formed in the housing; the connecting piece is provided with a first connector and a second connector; the inner wall of the gas inlet is provided with internal screw threads; the first connector is provided with external screw threads; and the first connector is connected with the gas inlet by the external screw threads and the internal screw threads. According to the utility model, the flowmeter main body and the connecting piece are assembled to form the novel flowmeter. Compared with the prior art, the novel carbon dioxide welding and gas cutting flowmeter has the advantages that preheating, pressure reduction and drying devices are removed; the novel carbon dioxide welding and gas cutting flowmeter can be connected with a flow divider valve by the second connector of the connecting piece; the gas outlet of the flowmeter main body can be connected with a corresponding cutting torch or welding torch by a rubber hose; and the novel carbon dioxide welding and gas cutting flowmeter not only has a simple and practical structure, but also reduces cost of equipment.
Description
Technical field
The utility model relates to a kind of carbon dioxide arc welding for central gas supply system and gas cutting new flowmeter.
Background technology
Gas shielded arc welding is to utilize gas as the electric arc medium and protect electric arc and the arc welding of weld zone, and carbon dioxide gas arc welding is a kind of in the gas shielded arc welding, is take carbon dioxide gas as protective gas, the method for welding.Gas cutting is after utilizing fuel gas and oxygen mix burned flame heat energy that the work piece cut place is preheating to uniform temperature, ejection high-speed cutting oxygen flow, make the metal vigorous oxidation and emit heat, utilize the cutting oxygen flow that the metal oxide of molten state is blown off, and realize the method for cutting; The used fuel gas of gas cutting mainly is acetylene, liquefied petroleum gas and hydrogen, and the injection that mixes and cut oxygen of fuel gas and oxygen utilizes cutting torch to finish, and cutting torch is Duoed an oxygen catheter than welding torch.
Prior art adopts supply station to carry out central gas supply, it comprises source of the gas, the gas treatment equipment with the source of the gas connection, the gas transmission supervisor who is connected with gas treatment equipment, is responsible for flow divider, the flowmeter that be connected corresponding to flow divider that is connected with gas transmission, each flowmeter connects corresponding cutting torch or welding torch by rubber hose again, realizes that with this many people carry out cutting or the welding of metal simultaneously.Wherein said gas treatment equipment is integrated with the equipment of preheating, decompression and functions/drying, described flowmeter generally is as one with preheater, pressure reducer, drier and flowmeter main body, be carbon dioxide decompression flowmeter, the standard that usually belongs to welding machine is equipped with at random.But, since the air supply system of supply station central gas supply formula at front end with the integrated setting of preheating, decompression and drying device, therefore the rear end just installs preheater, pressure reducer, drier additional so that complicated structure in flowmeter, has also increased the cost of equipment.
Summary of the invention
The utility model provides a kind of carbon dioxide arc welding for central gas supply system and gas cutting new flowmeter, and is simple and practical, and reduced equipment cost, has good practical value and economic worth.
A kind of carbon dioxide arc welding and gas cutting new flowmeter for central gas supply system, comprise flowmeter main body and connector, described flowmeter main body comprises shell and is arranged on air inlet and gas outlet on the shell, described connector is provided with the first connector and the second connector, the inwall of described air inlet is provided with internal thread, described the first connector is provided with external screw thread, and described the first connector and described air inlet interconnect by external screw thread and internal thread.
Aforesaid carbon dioxide arc welding and gas cutting new flowmeter for central gas supply system, the air inlet pipe front end in described air inlet is provided with filter screen.
Aforesaid carbon dioxide arc welding and gas cutting new flowmeter for central gas supply system are provided with sealing ring between described filter screen and the first connector.
The utility model fits together the formation new flowmeter with described flowmeter main body and described connector, it has compared with prior art removed preheating, decompression and drying device, can be connected with flow divider by the second connector of described connector, the gas outlet of flowmeter main body connects corresponding cutting torch or welding torch by rubber hose and gets final product; Not only simple and practical, and reduced the cost of equipment.
Description of drawings
Fig. 1 is that the utility model is used for the carbon dioxide arc welding of central gas supply system and the structural representation that gas cutting is used new flowmeter;
Fig. 2 is the cutaway view of part-structure of the present utility model.
Among the figure: 1-flowmeter main body, 2-connector, 11-shell, 12-air inlet, 13-gas outlet, 14-filter screen, 15-sealing ring, 21-the first connector, 22-the second connector.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is clearly and completely described.
Please refer to Fig. 1, carbon dioxide arc welding and gas cutting that the utility model is used for central gas supply system comprise flowmeter main body 1 and the connector 2 that links together with new flowmeter, wherein said flowmeter main body 1 comprises shell 11 and is arranged on air inlet 12 and gas outlet 13 on the shell 11; Described connector 2 is provided with the first connector 21 and the second connector 22.
Please further with reference to figure 2, the inwall of described air inlet 12 is provided with internal thread, and described the first connector 21 is provided with external screw thread, and described the first connector 21 interconnects by external screw thread and internal thread with described air inlet 12.Better, the air inlet pipe front end in described air inlet 12 is provided with filter screen 14, and described filter screen 14 can be used for the impurity in the gas that the filtering air inlet pipe provides, guarantees the pure and safety of air feed.In addition, between filter screen 14 and the first connector 21, also be provided with sealing ring 15, can increase the sealing property of pipe interior.
