Abstract
The invention discloses a sealing method for punching injection process pipe of an air conditioner with a flammable refrigerant. The sealing method comprises the following steps: 1) inwardly pressing pits on the side wall of the pipe port of the punching injection process pipe; 2) taking down a quick coupling at the pipe port of the punching injection process pipe; 3) coating a lock ring sealing liquid on the pipe port of the punching injection process pipe; 4) compressing a lock ring plug on the pipe port of the punching injection process pipe. The sealing performance of the lock ring plug is extremely good, so that small molecular substances such as the refrigerant can be prevented from being leaked; moreover, extremely high internal pressure can be sustained, and the sealing of the punching injection process pipe is realized by adopting the lock ring plug; the sealing method belongs to a purely mechanical mode, and the lock ring plug is compressed at the pipe port of the punching injection process pipe to realize sealing under the matching of the lock ring sealing liquid in a cold extruding mode; the sealing method is convenient to operate, reliable to seal and absolutely safe.
Description
Technical field
The present invention relates to the note process duct sealing tech field that rushes of combustible refrigerant air-conditioning, particularly a kind of adopt combustible refrigerant air-conditioning rush note process duct mouth-sealing method.
Background technology
For the consideration to environmental protection pressure, in worldwide, all accelerating to eliminate the cold-producing medium R22 that ozone layer is had to destruction at present, and substitute at present the R134a of R22, R410A, the cold-producing mediums such as R407C, because they have higher chamber effect potential value GWP, also will face by the destiny of control (eliminating), thereupon, the superior cold-producing medium of some environmental-protecting performances is applied as beginnings such as R32/R290 on domestic air conditioner, and the shortcoming of cold-producing medium R32/R290 is mainly the safety problem being caused by its combustibility, therefore in using the domestic air conditioner production process of combustible refrigerant, can not use traditional soldering naked light welding shutoff refrigerant charging technique mouth of pipe, otherwise can be very dangerous.
How providing a kind of and adopt rushing of combustible refrigerant air-conditioning to note process duct mouth-sealing method, to improve the security of sealing process, is the current technical issues that need to address of those skilled in the art.
Summary of the invention
The object of this invention is to provide a kind of adopt combustible refrigerant air-conditioning rush note process duct mouth-sealing method, to improve the security of sealing process.
For solving the problems of the technologies described above, the invention provides following scheme:
What adopt combustible refrigerant air-conditioning rushes a note process duct mouth-sealing method, comprising: step 1): on the sidewall of the mouth of pipe of described punching note process duct, inwardly extrude pit; Step 2) take off the snap joint of the mouth of pipe that is positioned at described punching note process duct; Step 3) on the mouth of pipe of described punching note process duct, apply Lip river gram ring sealing fluid; Step 3) Lip river gram ring plug is pressed on the mouth of pipe of described punching note process duct.
Preferably, above-mentioned steps 1) be specially the circular salient point adopting on gram ring seal brank of Lip river inwardly extrude pit on the sidewall of the mouth of pipe of described punching note process duct.
Preferably, above-mentioned steps 3) be specially first a described Lip river gram ring plug rotary sleeve is located on the mouth of pipe of described punching note process duct, then adopt Lip river gram ring seal brank that a described Lip river gram ring plug is pressed on the mouth of pipe of described punching note process duct.
Process duct mouth-sealing method is noted in rushing of the employing combustible refrigerant air-conditioning that the invention described above provides, and comprising: step 1): on the sidewall of the mouth of pipe that rushes note process duct, inwardly extrude pit; Step 2) take off the snap joint of the mouth of pipe that is positioned at punching note process duct; Step 3) on the mouth of pipe of punching note process duct, apply Lip river gram ring sealing fluid; Step 3) a Lip river gram ring plug is pressed on the mouth of pipe of punching note process duct, the sealing of Luo Ke ring plug is very good, can stop small-molecule substance as the leakage of cold-producing medium, and can bear sizable interior pressure, adopt Lip river gram ring plug to realize the sealing of punching note process duct, belong to pure mechanical system, by cold-stamped mode, under the cooperation of Lip river gram ring sealing fluid, the mouth of pipe that Lip river gram ring plug is pressed on to punching note process duct, completes sealing, easy to operate, sealing is reliable, and is perfectly safe.Meanwhile, it should be noted that must first on the sidewall of the mouth of pipe that rushes note process duct, inwardly extrude pit notes process duct to close punching, and then take off the snap joint of the mouth of pipe that is positioned at punching note process duct, prevent the leakage of combustible refrigerant air-conditioning.
Accompanying drawing explanation
The schematic flow sheet that rushes note process duct mouth-sealing method of the employing combustible refrigerant air-conditioning that Fig. 1 provides for the embodiment of the present invention.
The specific embodiment
In order to make those skilled in the art understand better the present invention program, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1, the schematic flow sheet that rushes note process duct mouth-sealing method of the employing combustible refrigerant air-conditioning that Fig. 1 provides for the embodiment of the present invention.
Process duct mouth-sealing method is noted in rushing of the employing combustible refrigerant air-conditioning that the embodiment of the present invention provides, and comprising: step 1): on the sidewall of the mouth of pipe that rushes note process duct, inwardly extrude pit; Step 2) take off the snap joint of the mouth of pipe that is positioned at punching note process duct; Step 3) on the mouth of pipe of punching note process duct, apply Lip river gram ring sealing fluid; Step 3) a Lip river gram ring plug is pressed on the mouth of pipe of punching note process duct, the sealing of Luo Ke ring plug is very good, can stop small-molecule substance as the leakage of cold-producing medium, and can bear sizable interior pressure, adopt Lip river gram ring plug to realize the sealing of punching note process duct, belong to pure mechanical system, by cold-stamped mode, under the cooperation of Lip river gram ring sealing fluid, Lip river gram ring plug is pressed on to the mouth of pipe of punching note process duct, complete sealing, easy to operate, sealing is reliable, and is perfectly safe, and has improved the security of sealing process.Meanwhile, it should be noted that must first on the sidewall of the mouth of pipe that rushes note process duct, inwardly extrude pit notes process duct to close punching, and then take off the snap joint of the mouth of pipe that is positioned at punching note process duct, prevent the leakage of combustible refrigerant air-conditioning.
In order further to optimize such scheme, step 1) be specially the circular salient point adopting on gram ring seal brank of Lip river inwardly extrude pit on the sidewall of the mouth of pipe of punching note process duct.Lip river gram ring seal brank is special and the Lip river gram instrument that ring plug is used in conjunction with, and uses convenient, certain, also can use other, such as pliers or fixture etc., realizes on the sidewall of the mouth of pipe that rushes note process duct and inwardly extrudes pit, to close punching, notes process duct.
