Abstract
The utility model relates to an economizer of argon filled in a pipeline for protection. The economizer of argon filled in a pipeline for protection includes an argon-protected short tube (9), which is provided with rows of holes (4) and on both ends of which left and right steel plates (2, 11) are fixed, a high-pressure rubber sheet (3) and a steel plate (6) are orderly fixed on the other side of the left steel plate (2) by a nut (1) and a bolt, and a high-pressure rubber sheet (3) and a steel plate (6) are orderly fixed on the other side of the right steel plate (11) by a nut (1) and an external screw tube (12) which is connected with a hose (7) by means of a tie-in (5). The economizer of argon filled in a pipeline for protection can seal both ends of the weld seam of a pipeline, so that argon is not leaked, thus saving production cost, and welding quality can reach 100 percent.
Description
Technical field:
The utility model relates to the used a kind of instrument of oil field welding field, argon-filled protection energy-saving appliance in especially a kind of pipe.
Background technology:
In the present pipe during argon-filled protection welding, need charging into a large amount of argon gas in managing, but, make welding quality can not reach 100% because not sealing of pipeline make and cause waste by a large amount of gas loss, and specific aim is bad.
The utility model content:
In order to solve the problem in the background technology, the utility model provides argon filling energy-saving appliance in a kind of pipe, and the interior argon filling energy-saving appliance of this pipe can make weld bond sealed at both ends of pipeline, and argon gas does not run off, and has saved production cost, and welding quality can reach 100%.
The technical solution of the utility model is: the argon filling energy-saving appliance comprises the argon shield short tube in this pipe; the argon shield short tube has several rows of hole; the two ends of argon shield short tube are fixed with left and right steel plate respectively; the another side of left plate is fixed with high pressure rubber and steel plate successively by nut and bolt; the another side of right steel plate is fixed with high pressure rubber and steel plate successively by nut and male-pipe, and male-pipe is connected with sebific duct by short circuit.
Above-mentioned sebific duct is with protection tube outward, and protection tube links to each other with male-pipe.
The utlity model has following beneficial effect: this novel welded seam that is primarily aimed at is carried out argon-filled protection, and effectively prevents gas loss, can reach weld bond 100% qualification rate.Argon gas does not run off and has saved material and easy, practical, instant dress, and good airproof performance prevents from internal oxidation from can effectively guarantee welding quality during to stainless steel, steel alloy welding.
Description of drawings:
Accompanying drawing 1 is a partial sectional view of the present utility model.
1-nut among the figure, 2-left plate, 3-high pressure rubber, 4-hole, 5-short circuit, 6-steel plate, 7-sebific duct, 8-mother metal, 9-argon shield short tube, 10-protection tube, the right steel plate of 11-, 12-male-pipe.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing: as shown in the drawing; the argon filling energy-saving appliance comprises argon shield short tube 9 in this pipe; argon shield short tube 9 has several rows of hole 4; charge into argon gas 4 outflows in the mother metal 8 from the hole; the two ends of argon shield short tube 9 are fixed with a left side respectively; right steel plate (2; 11); the another side of left plate 2 is fixed with high pressure rubber 3 and steel plate 6 successively by nut 1 and bolt; the two ends that high pressure rubber 3 is used to seal weld bond are not run off argon gas; a left side; right steel plate (2; 11) and steel plate 6 be used for fixing high pressure rubber 3; the another side of right steel plate 11 is fixed with high pressure rubber 3 and steel plate 6 successively by nut 1 and male-pipe 12; male-pipe 12 is connected with sebific duct 7 by short circuit 5, is with protection tube 10 outside the sebific duct 7, and protection tube 10 links to each other with male-pipe 12.
During actual the use; behind the pipe tack welding; range measurement with keeping device and pipe end is good outside earlier; on element number 10, carry out mark; then keeping device is sent into and the position is ajusted; argon gas flow in the argon shield short tube 9 through male-pipe 12 from sebific duct 7, and argon gas is 4 outflow protection weld seams from the hole, in the welding process; at pipe half-turn protection welding; can save the half-turn argon gas, weld half-turn and adjusted the position and weld opposite side again, keeping device be taken out after having welded the first pass weld bond; carrying out the weld bond welding until having welded; weld effective, the inner non-oxidation of weld seam; lack of penetration phenomenon reaches technical standard.
Claims (2)
1, argon filling energy-saving appliance in a kind of pipe; comprise argon shield short tube (9); it is characterized in that: argon shield short tube (9) has several rows of hole (4); the two ends of argon shield short tube (9) are fixed with left and right steel plate (2 respectively; 11); the another side of left plate (2) is fixed with high pressure rubber (3) and steel plate (6) successively by nut (1) and bolt; the another side of right steel plate (11) is fixed with high pressure rubber (3) and steel plate (6) successively by nut (1) and male-pipe (12), and male-pipe (12) is connected with sebific duct (7) by short circuit (5).
2, argon filling energy-saving appliance in the pipe according to claim 1 is characterized in that: sebific duct (7) is outer to be with protection tube (10), and protection tube (10) links to each other with male-pipe (12).
