Abstract
The utility model discloses a refrigerant-charging device for charging a refrigerant to a full-close type refrigerating device. The utility model is characterized in that the central shaft line of the push rod of a pipe expander is drilled with a through hole. The utility model is used for charging the refrigerant to the full-close type refrigerating device, having simple and reliable operation, simple structure and low cost and being suitable for various pipe mouths with different pipe diameters.
Description
" device of perfusion cold-producing medium " is to be used for cold-producing medium is injected into Totally-enclosed type refrigeration equipment, injects fluid into the invention of the device in the full hermetic container in other words conj.or perhaps.
The device of known perfusion cold-producing medium is: the inlet of Totally-enclosed type refrigeration equipment cold-producing medium is a copper pipe, the outer end of copper pipe connects with valve, after Open valve injects an amount of cold-producing medium, valve-off, flat copper pipe somewhere folder again, unload lower valve after, with solder flux the weldering of copper pipe mouth is blocked, make cold-producing medium not reach the purpose of notes, blocking refrigerant from the mouth of pipe to external leakage.The shortcoming of this method is: because the external diameter of inlet copper pipe does not coexist when injecting cold-producing medium, concerning producer and maintenance personal, to prepare the connection copper pipe and the valve of plurality of specifications, and operation inconvenience.
The present invention is exactly for solving this difficulty, make in the process of Totally-enclosed type refrigeration equipment being poured into cold-producing medium easy and simple to handle reliable, feature of the present invention is: pipe-expander is changed a social system, mouth of pipe expanding device push rod axis along pipe-expander drills through an aperture, refrigeration plant inlet copper pipe is clipped in the pipe-expander anchor clamps, withstands the mouth of pipe, in the mouth of pipe, rotate top with the push rod tip of the mouth of pipe expanding device of pipe-expander, make the horn mouth contact-making surface of spreading tight, no gap.The other end of pipe-expander push rod connects with valve, and Open valve makes the aperture of cold-producing medium by the mouth of pipe expanding device push rod of pipe-expander be injected into purpose in the refrigeration plant.
Fig. 1 is the pipe-expander anchor clamps.
Fig. 2 is the mouth of pipe expanding device of pipe-expander, and the push rod axis has a through hole.
Fig. 3 is the schematic diagram that injects cold-producing medium with pipe-expander.
Totally-enclosed type refrigeration equipment such as refrigerator, its inlet that injects cold-producing medium is a copper pipe.When injecting cold-producing medium, copper pipe is clamped with pipe-expander anchor clamps shown in Figure 1, mouth of pipe expanding device with pipe-expander shown in Figure 2 is stuck on the pipe-expander anchor clamps then, and rotation push rod A, with the top of push rod A the copper pipe mouth is risen into by trumpet type, make the top of push rod A and copper pipe horn mouth contact-making surface tight, very close to each other, the other end of push rod A connects with valve, Open valve, and cold-producing medium is annotated in the system cool equipment through the aperture B of push rod A shown in Figure 3, valve-off is finished the purpose of pouring into cold-producing medium.
Use device of the present invention, easy and simple to handle reliable, and be applicable to the mouth of pipe of various different tube diameters, simple equipments reduces cost, and increases the benefit.
Claims (1)
1, be used to pour into the device of cold-producing medium, it is characterized in that: a through hole is bored at the central axis place at the pipe-expander push rod.
