Abstract
The utility model discloses a seal type chlorofluoromethane injector for a refrigerator, as shown in figure 1, comprising a container with liquid level indication, a vacuum pressure gauge, a valve and a connecting pipe. When the injector is used, the desired chlorofluoromethane can be once injected into the refrigerator in quantity; the seal type chlorofluoromethane injector for a refrigerator overcomes the defects of complicated weighing operation, repeated and inaccurate injection, and empirical estimation; the chlorofluoromethane can be saved.
Description
The utility model belongs to the technical field that closed refrigerator fills cold-producing medium.
For closed refrigerator fills the cold-producing medium F-12, the method for using is weight method (seeing Shanghai Communications University " refrigerating plant and air conditioning basis ", the Xia Anshi chief editor) at present, or estimates by rule of thumb.Weight method is that the freon steel cylinder is placed on the platform scale, determines the charging amount of F-12 by the weight difference that fills process front and back steel cylinder.
The weight method complicated operating process often needs repeated multiple times to fill and just can reach the required amount of refrigerator, and accuracy is also relatively poor.Estimation by rule of thumb fills F-12, has filled and has bled off, and fills to have lacked to add again, and blindness is big, needs repeated multiple times to fill the amount that just can reach needs equally, is easy to cause the waste of F-12 and the increase in man-hour.
The purpose of this utility model provides a kind of filled device that can once quantitatively fill F-12, once quantitatively fills F-12 can for closed refrigerator.
The valve (3) that the utility model is connected successively by tube connector (13), have container (4), valve (5), the valve (6) of liquid level indication and be connected on valve (5) and valve (6) between pressure vacuum gauge (9) formed.The pressure that container (4), pressure vacuum gauge (9), three valves (3), (5), (6) and tube connector (13) can bear is in 15 kilograms per centimeter
2More than.Its operation principle following (seeing accompanying drawing 1): open vavuum pump (8), distinguish Open valve (3), (5), (6) then, total system vacuumizes.After pressure vacuum gauge (9) indicated and reaches required vacuum, valve-off (5) was opened F-12 steel cylinder (1), and F-12 liquid just injects container (4).Observe liquid level in the container (4), arrive aequum after, valve-off (3) immediately.Valve-off (6) is opened valve (5) again, and the F-12 in the container (4) just once all injects refrigerator (11).
Use this filled device, F-12 that can refrigerator is required once quantitatively fills, and can save F-12 and simple to operate like this.
Accompanying drawing 1 is a schematic diagram of the present utility model.Accompanying drawing 2 is specific embodiments of the present utility model.With tube connector (13) jointing successively (2), valve (3), have container (4), valve (5), joint (10), valve (6), the joint (7) of liquid level indication, connect pressure vacuum gauge (9) between valve (5) and (6), they all place wooden case (12).And with tube connector joint (2), (7), (10), the handwheel of valve (3), (5), (6), the surface of pressure vacuum gauge (9), place on the panel in the wooden case (12), on the panel of container (4) top, open a window, so that observe the amount of the F-12 that injects container (4) with liquid level indication.During use, tube connector joint (2) is connected with the F-12 steel cylinder, and tube connector joint (7) is connected with vavuum pump, and tube connector joint (10) is connected with freezer compressor.
By specific embodiment shown in Figure 2,, also has advantage easy to carry except that saving F-12 and save man-hour than the weight method and the experience estimation technique.
Claims (1)
1, a kind of filled device of closed refrigerator F-12, it is characterized in that by tube connector [13] connect valve [3] successively, container [4], valve [5], pressure vacuum gauge [9], valve [6] with liquid level indication form.
