Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0031] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] The present application provides a gas furnace valve body flow testing device, comprising a flow meter 23, at least two groups of plugging components, a controller and a testing tool; wherein at least two groups of plugging components are spaced apart and arranged on the testing tool, and the controller is electrically connected to the flow meter 23 and the plugging components.

[0033] like Figure 1 As shown, the gas furnace valve body flow test device is suitable for performing flow test on the first valve body 10 and the second valve body 11 of the gas furnace, wherein the gas furnace comprises a bottom shell 15, and the bottom shell 15 is provided with an air inlet pipe 14, a first knob 12 and a second knob 13; the air inlet pipe 14 is connected to both the first valve body 10 and the second valve body 11. The first valve body 10 is connected with a first nozzle 100, and the first knob 12 is used to control the connection and disconnection between the first nozzle 100 and the air inlet pipe 14; the second valve body 11 is connected with a second nozzle 110, and the second knob 13 is used to control the connection and disconnection between the second nozzle 110 and the air inlet pipe 14.

[0034] like Figure 2In a specific embodiment of the gas furnace valve body flow test device shown, the gas furnace valve body flow test device also includes a switch assembly, an indicator light and a reset switch 42; wherein, the number of the blocking assemblies is two groups, and the two groups of blocking assemblies are respectively a first blocking assembly and a second blocking assembly.

[0035] It is understandable that the flow meter 23 is detachably connected to the air intake pipe 14 through a test tube. When the bottom shell 15 is placed on the test fixture, the first plugging assembly is located above the first nozzle 100, and the second plugging assembly is located above the second nozzle 110. Specifically, the first plugging assembly includes a first cylinder 20 and a first plugging head, and the first plugging head is arranged at the end of the piston rod of the first cylinder 20; the second plugging assembly includes a second cylinder 21 and a second plugging head, and the second plugging head is arranged at the end of the piston rod of the second cylinder 21. The controller is electrically connected to the first cylinder 20 and the second cylinder 21.

[0036] Specifically, when the first knob 12 and the second knob 13 are both fully opened, the controller can control the second cylinder 21 to move downward, the second blocking head blocks the second nozzle 110, and at the same time the controller can start the flow meter 23 to supply air to the intake pipe 14 to test the first state of the flow of the first valve body 10; the controller can also control the first cylinder 20 to move downward, the first blocking head blocks the first nozzle 100, control the second cylinder 21 to retract, open the second nozzle 110, and then start the flow meter 23 to supply air to the intake pipe 14 to test the second state of the flow of the second valve body 11.

[0037] Optionally, the flow meter 23 is provided with an I\O interface. During testing, the flow meter 23 sends a failed signal or a qualified signal to the controller through the I\O interface. It is suitable for sending a failed signal to the controller when the test flow fails. The controller can control the operation of the flow meter 23, the first cylinder 20 and the second cylinder 21 according to the failed signal or the qualified signal.

[0038] Specifically, the flow meter 23 can record flow data and output a qualified or unqualified signal; the output pressure range of the flow meter 23 is: 0.4MPa ~ 0.69MPa.

[0039] The switch assembly is provided with a first switch 40 and a second switch 41, and the first switch 40 and the second switch 41 are respectively connected to the controller; wherein, when the controller receives a signal that the first switch 40 and the second switch 41 are pressed simultaneously, the controller controls the flow meter 23 and the blocking assembly to start, thereby improving the safety of the operation.

[0040] The reset switch 42 is electrically connected to the controller; when the flow test fails and is paused, by pressing the reset switch 42, the controller controls the blocking component to reset and the flow meter 23 to close, so as to facilitate the removal of unqualified products.

[0041] Optionally, the indicator light is connected to a controller, and when the controller receives an unqualified signal, the indicator light of the controller lights up, and the indicator light may be a red indicator light. Specifically, the controller is an integrated circuit board or a programmable controller, and the controller may be arranged in a control cabinet 22. Further, the first switch 40, the second switch 41 and the reset switch 42 are all arranged on the same operation panel 43 for easy operation.

[0042] The test fixture is provided with a positioning assembly, and the positioning assembly is used to position the bottom shell 15. Optionally, the positioning assembly includes a first adjusting screw 310, a second adjusting screw 320 and a positioning block 30. Wherein, the test fixture includes: a bottom plate 34, a first vertical plate 31, a second vertical plate 32 and a top plate 33. The bottom plate 34 is suitable for placing the bottom shell 15. The first vertical plate 31 and the second vertical plate 32 are respectively located on the left and right sides of the bottom shell 15, and the bottom ends of the first vertical plate 31 and the second vertical plate 32 are both connected to the bottom plate 34; the first adjusting screw 310 is threadedly connected to the first vertical plate 31, and the second adjusting screw 320 is threadedly connected to the second vertical plate 32.

[0043] It is understandable that the bottom shell 15 is placed on the bottom plate 34 , and by adjusting the first adjusting screw 310 and the second adjusting screw 320 , the first adjusting screw 310 and the second adjusting screw 320 are in contact with both sides of the bottom shell 15 to achieve positioning of the left and right sides of the bottom shell 15 .

[0044] The top plate 33 is connected to the top ends of the first vertical plate 31 and the second vertical plate 32. The positioning block 30 is arranged on the bottom plate 34 and is located on one side of the vertical plate adjacent to the top plate 33. Optionally, two groups of positioning blocks 30 are provided. The two groups of positioning blocks 30 are symmetrically arranged on the bottom plate 34. The positioning blocks 30 are detachably connected to the bottom plate 34 by locking screws. The shape of the positioning blocks 30 can be L-shaped. Furthermore, the positioning blocks 30 are provided with strip holes (not shown in the figure) extending in the front-to-back direction. The locking screws are passed through the strip holes to facilitate the adjustment of the front-to-back position of the positioning blocks 30. The rear side of the bottom shell 15 is positioned by the positioning blocks 30 contacting with the rear side of the bottom shell 15.

[0045] It can be understood that the bottom shell 15 is positioned by the first adjusting screw 310 , the second adjusting screw 320 and the positioning block 30 . When the bottom shell 15 is placed on the bottom plate 34 , it is convenient for the first cylinder 20 to align with the first nozzle 100 , and for the second cylinder 21 to align with the second nozzle 110 .

[0046] The use process of the gas furnace valve body flow testing device described in the present application is briefly described as follows.

[0047] S1. Preparation: electrically connect the controller to the first cylinder 20, the second cylinder 21, and the flow meter 23, debug the positioning assembly of the test fixture, debug the stroke of the first cylinder 20 and the second cylinder 21, and set the test parameters of the flow meter 23.

[0048] S2. Place and position the bottom shell 15: Place the bottom shell 15 into the test fixture. The left and right sides of the bottom shell 15 are respectively against the first adjustment screw 310 and the second adjustment screw 320. The rear side of the bottom shell 15 is close to the positioning block 30. The test tube is used to connect the air intake pipe 14 and the flow meter 23.

[0049] S3, test the first valve body 10: open the first knob 12 and the second knob 13 completely, and press the first switch 40 and the second switch 41 with both hands to trigger the controller synchronously. The controller controls the second cylinder 21 to press down, seal and block the second nozzle 110, and the first nozzle 100 remains open. The flow meter 23 starts and performs a flow test. After the test is completed, the flow meter 23 outputs a signal to the controller that the test flow is qualified or unqualified. When the controller receives a signal that the test flow is unqualified, the first cylinder 20, the second cylinder 21 and the flow meter 23 will stop running, and the indicator light will light red. At this time, the reset switch 42 can be manually pressed, and the first cylinder 20 and the second cylinder 21 can be retracted to remove the unqualified gas furnace. When the controller receives a signal that the test flow is qualified, it automatically jumps to the next step.

[0050] S4, test the second valve body 11: the controller automatically controls the second cylinder 21 to retract, the first cylinder 20 to press down, the first nozzle 100 to be sealed, the second nozzle 110 is in an open state, the flow meter 23 is started, and a flow test is performed. After the test is completed, the flow meter 23 outputs a signal that the test flow is qualified or unqualified. When the controller receives a signal that the test flow is unqualified, the first cylinder 20, the second cylinder 21 and the flow meter 23 will stop running, and the indicator light will light red. The reset switch 42 needs to be manually opened, and the first cylinder 20 and the second cylinder 21 are both retracted to remove the unqualified gas furnace. When the controller receives a signal that the test flow is qualified, the first cylinder 20 and the second cylinder 21 are both retracted.

[0051] S5. Take out the gas furnace: take out the gas furnace and then test the next gas furnace.

[0052] The technical solution of the present application uses a controller to associate the first cylinder 20, the second cylinder 21 and the flow meter 23. After the gas furnace to be tested is positioned, the operator only needs to start the first switch 40 and the second switch 41 once, and the first cylinder 20 and the second cylinder 21 automatically block the first nozzle 100 or the second nozzle 110, and start the test synchronously. After completing the flow test of the first valve body 10, it automatically switches to the flow test of the second valve body 11. After the test is qualified, the first cylinder 20 and the second cylinder 21 are automatically retracted, which improves the flow test efficiency of the gas furnace valve body. Since the test waiting time of employees is long after adopting the above technical solution, one person can consider multi-machine operation to further improve production efficiency.

[0053] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
