DETAILED DESCRIPTION OF THE EMBODIMENTS
[0026] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0027] In order to facilitate the addition of a quantitative adjustment mechanism and improve the accuracy of adding refrigerant by means of secondary adjustment, thereby improving the use effect, as Figures 1-3 shown, a quantitative liquid adding device for central air conditioner maintenance and repair according to the present utility model includes a housing 1, an adjusting component 3 and a pushing component 4. The top of the housing 1 is connected by welding with a threaded seat 2. The adjusting component 3 is sleeved in the housing 1 and penetrates through the threaded seat 2. The pushing component 4 is arranged in the adjusting component 3. A reflux component 5 is arranged on one side of the housing 1, and a diversion component 6 is arranged at the bottom of the housing 1;
[0028] The adjusting assembly 3 includes a threaded rod 301, and the threaded rod 301 is threadedly connected to the threaded seat 2. One end of the threaded rod 301 is located inside the housing 1 and is bolted to a sealing seat 302, and the other end of the threaded rod 301 is bolted to a fixing seat 303 on the periphery.
[0029] During use, through the housing 1, the threaded seat 2, the threaded rod 301, the sealing seat 302 and the fixing seat 303, an auxiliary quantitative adjustment mechanism can be added. After quantitatively adding refrigerant to the liquid adding device, a secondary quantitative adjustment process is performed on it, thereby improving the accuracy of the liquid adding operation and reducing resource waste at the same time.
[0030] To improve the convenience of operation, by way of example, as Figure 1 , Figure 2 shown, the present utility model further includes that the pushing assembly 4 includes a push rod 401, and the threaded rod 301 is sleeved and connected to the push rod 401. The top of the push rod 401 is welded to a pressing plate 402, and a compression spring 404 is sleeved on the periphery of the push rod 401 between the fixing seat 303 and the pressing plate 402.
[0031] During use, through the push rod 401 and the pressing plate 402, it is convenient to inject the refrigerant into the central air conditioner by using the pushing action. Through the elastic driving force of the compression spring 404, after the quantitative liquid adding operation is completed, the pushing assembly 4 can be quickly driven to slide back to its original position, thereby improving the convenience of continuous use of the liquid adding device, and at the same time, it can also play a function of pre - assisting in extraction and feeding, further improving the use effect and functionality of the liquid adding device.
[0032] By way of example, as Figure 3 shown, the present utility model further includes that the reflux assembly 5 includes a reflux tank 501. A conduit 502 is provided at the top of the reflux tank 501, and the conduit 502 communicates with the housing 1. A control valve 503 is provided at one end of the conduit 502.
[0033] During use, through the reflux tank 501, the conduit 502 and the control valve 503, a reflux assembly 5 can be formed to recover the excess refrigerant during the secondary quantitative adjustment operation, thereby reducing resource waste. The reflux tank 501 includes a pressure relief port.
[0034] By way of example, as Figure 2 shown, the present utility model further includes that a positioning screw 304 is threadedly connected to the surface of the threaded rod 301 through a reserved threaded hole, and one end of the push rod 401 is bolted to a piston 403 at the bottom of the threaded rod 301.
[0035] During use, the push rod 401 can be conveniently limited and fixed through the positioning screw 304, and the sealing performance of temporarily storing refrigerant in the housing 1 can be improved through the piston 403.
[0036] Exemplarily, such as Figure 1 As shown, the present utility model further includes that the flow guiding assembly 6 includes a liquid injection pipe 601, and the liquid injection pipe 601 is communicated with the discharge end of the housing 1. One end of the liquid injection pipe 601 is provided with a liquid injection head 602, and the feed end of the liquid injection pipe 601 is provided with an electromagnetic valve 603.
[0037] During use, through the liquid injection pipe 601, the liquid injection head 602 and the electromagnetic valve 603, it is convenient to introduce the refrigerant into the central air-conditioning cabinet during the process of pushing the refrigerant for liquid addition.
[0038] Exemplarily, such as Figure 1 、 Figure 2 As shown, the present utility model further includes that scale lines 101 are provided on the surface of the housing 1. A liquid filling port 102 is opened on the surface of one side of the housing 1. The housing 1 is of a transparent structure and is made of polystyrene material.
[0039] During use, through the scale lines 101, it is convenient to observe the refrigerant capacity in the housing 1. Through the liquid filling port 102, it is convenient to quantitatively add the refrigerant into the housing 1 from the outside. The liquid filling port 102 includes a sealing plug.
[0040] When the present utility model is in use, first, the operator pre-introduces the refrigerant into the housing 1 through the liquid filling port 102. After closing the liquid filling port 102, the device is placed reversely so that the adjusting assembly 3 and the pushing assembly 4 are at the bottom. By manually rotating the fixing seat 303 to drive the threaded rod 301 to be threadedly connected to the threaded seat 2, the threaded rod 301 drives the sealing seat 302 to slide towards the inside of the housing 1. Manually open the electromagnetic valve 603, and the air in the housing 1 can be discharged outwards through the liquid injection pipe 601 and the liquid injection head 602 until the refrigerant flows out and then stop the operation. At this time, close the electromagnetic valve 603, open the control valve 503, reverse the liquid filling device again, rotate the fixing seat 303, and use the scale lines 101, the sealing seat 302 and the piston 403 to push the excess refrigerant into the return groove 501 for recovery, thereby improving the accuracy of quantitative addition of the refrigerant. Then connect the liquid injection head 602 of the flow guiding assembly 6 to the central air-conditioning, and by pressing the pressing plate 402 to drive the push rod 401 and the piston 403 to slide downwards, the refrigerant is pushed into the central air-conditioning cabinet through the flow guiding assembly 6 to complete the quantitative liquid addition operation;
[0041] While completing the liquid addition operation, it is necessary to turn the positioning screw 304 to limit and fix the push rod 401. After the flow guiding assembly 6 is taken out, the elastic force of the compression spring 404 is used to push the pressing plate 402 to slide upwards for resetting. It is not only convenient and fast to operate, but also can pre-draw and take the refrigerant through the above operations, further improving the convenience and flexibility of the use of the liquid filling device. The structure is simple, the cost is low, and the use is more convenient and reliable.
