It collects refrigerant or other liquids from various branch pipes and then discharges or treats them through outlet branch pipes. During the manufacturing process, multiple branch pipes are welded to the main manifold body. It is necessary to inspect the finished product for blockages in each branch pipe, including the inlet and outlet branch pipes. Current technology typically relies on manual inspection, which is inefficient. Utility Model Content

If it can be inserted, it means that the production is qualified; if it cannot be inserted, it means that the production is unqualified.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] The following is in conjunction with the appendix Figure 1-2This application provides a further detailed description. An embodiment of this application discloses a venting detection device for a liquid collection pipe. It includes a housing 1, with an outlet 102, an inlet 103, an inlet interface 101, and an outlet interface 104 on the outer surface of the housing 1. The outlet 102 is connected to the inlet interface 101, and the inlet 103 is connected to the outlet interface 104. The outlet interface 104 is connected to a venting detection device 2 via a pipe. The outlet 102 and inlet 103 are used to connect to branch pipes of the liquid collection pipe to be tested. By connecting an external air source to the inlet interface 101, gas flows out from the outlet 102 (connected to the inlet interface 101) and into the liquid collection pipe. After passing through the inside of the liquid collection pipe, the gas enters the inlet 103 of the housing 1 through the branch pipe of the liquid collection pipe, flows from the inlet 103 to the outlet interface 104, and then enters the venting detection device 2 through a pipe from the outlet interface 104. When the ventilation detection device 2 detects gas, it indicates that the branch pipe of the liquid collection pipe corresponding to the ventilation detection device 2 is not blocked. When the ventilation detection device 2 does not detect gas, it indicates that the branch pipe of the liquid collection pipe corresponding to the ventilation detection device 2 is blocked.

[0021] Furthermore, the number of air outlets 102 corresponds to the number of air inlets 103. Typically, one liquid collection tube corresponds to one air outlet 102, and one air outlet 102 corresponds to one air inlet 101; the number of air outlets 102 corresponds one-to-one with the number of air inlets 101. When multiple liquid collection tubes need to be measured simultaneously in the same housing 1, the number of air outlets 102 also corresponds one-to-one with the number of liquid collection tubes to be tested.

[0022] Furthermore, the number of air outlets 104 corresponds to the number of air inlets 103, ensuring that one air inlet 103 corresponds to one air outlet 104. The liquid collection pipe must collect liquid from at least two pipes and concentrate it into one pipe; therefore, the liquid collection pipe is connected to at least three branch pipes. One branch pipe of the liquid collection pipe must be connected to an air outlet 102, and the other branch pipes of the liquid collection pipe are connected to their corresponding air inlets 103. Furthermore, the number of ventilation detection devices 2 corresponds to the number of air outlets 104, enabling the ventilation detection devices 2 to accurately detect which air outlet 104 is not emitting air, thereby determining whether the branch pipe of the liquid collection pipe connected to the air inlet 103 corresponding to that air outlet 104 is blocked. For example, in this embodiment, if the liquid collection pipe has three pipes, two air inlets 103 are provided. The three pipes are respectively connected to one air outlet 102 and two air inlets 103. One air outlet 102 corresponds to one air inlet 101, and the two air inlets 103 correspond to two air outlets 104. The two air outlets 104 also correspond to two ventilation detection devices 2. Gas enters the housing 1 from the air inlet 101, enters one of the pipes of the liquid collection pipe from the air outlet 102, and then enters the corresponding two air inlets 103 of the housing 1 from the other two pipes of the liquid collection pipe, and is then detected by the ventilation detection devices 2. In this case, even if more air inlets 103 and corresponding ventilation detection devices 2 are provided, it will not be affected. As long as one branch pipe of the liquid collection pipe is connected to the air outlet 102, the other branch pipes of the liquid collection pipe can be detected by the ventilation detection devices 2 corresponding to the air inlets 103.

[0023] Furthermore, the ventilation detection device 2 includes a housing with a detection interface 201 connected to the air outlet 104 via a pipe. The housing contains a detection liquid, which includes water, foaming liquid, and a foaming agent solution—a common liquid for observing bubble formation. Airflow flows from the air outlet 104 to the detection interface 201 and then enters the housing. Whether airflow enters the housing is determined by whether the detection liquid bubbles. The water level of the detection liquid is higher than the height of the detection interface 201 relative to the bottom of the housing, ensuring that gas entering the ventilation detection device 2 through the detection interface 201 can be detected by the detection liquid.

[0024] Furthermore, the chamber is equipped with an anti-backflow pipe. The air inlet of the anti-backflow pipe is connected to the detection interface 201, and the air outlet of the anti-backflow pipe extends into the chamber and bends towards the bottom of the chamber, so that the detection liquid with a liquid level higher than the detection interface 201 will not flow back from the detection interface 201 to the air outlet 104 of the chamber 1.

[0025] Furthermore, the air outlet 102 and air inlet 103 can be connected to the air inlet 101 and air outlet 104 respectively via pipes. Alternatively, at least two sealed spaces can be provided within the housing 1, such that the air outlet 102 and air inlet 101 are located in the same sealed space, and the air inlet 103 and air outlet 104 are located in the same sealed space. For example, when the liquid collection pipe has three branch pipes, each branch pipe corresponds to one sealed space, and more sealed spaces are provided according to the number of branch pipes available for different specifications of liquid collection pipes.

[0026] Furthermore, both the air outlet 102 and the air inlet 103 are equipped with annular rubber rings. Both the air outlet 102 and the air inlet 103 are press-fitted with the liquid collection pipe via these annular rubber rings to improve the sealing of the connection between the air outlet 102 or the air inlet 103 and the liquid collection pipe. Simultaneously, the location of the air outlet 102 and the air inlet 103 within the housing 1 can also be used to detect whether each section of the liquid collection pipe meets the set specifications. For example, if any branch of the liquid collection pipe has an improper degree of bending or other physical errors, the branch cannot be smoothly inserted into the air outlet 102 and / or the air inlet 103, thus determining that the branch is manufacturing defective and should be reworked without further assessment of the internal ventilation of the liquid collection pipe.

[0027] Working principle: Connect an external air source to the air inlet 101, and insert each pipe of the liquid collection tube into the air outlet 102 and air inlet 103 respectively. If any pipe of the liquid collection tube cannot be inserted into the air outlet 102 and / or air inlet 103, the liquid collection tube is deemed unqualified. After all pipes of the liquid collection tube are inserted into the air outlet 102 and air inlet 103, start the external air source to inflate the air inlet 101. The airflow enters the housing 1 from the air inlet 101, then flows through the air outlet 102 to the liquid collection tube. After passing through the liquid collection tube, the airflow flows from the air inlet 103 to the air outlet 104, and then to the ventilation detection device 2. If the ventilation detection device 2 does not detect gas, it indicates that the branch pipe of the liquid collection tube connected to the ventilation device is blocked. If all ventilation detection devices 2 do not detect gas, it indicates that the branch pipe connected to the air outlet 102 is blocked, or all branch pipes are blocked, requiring further manual judgment.
