Description

Technical Field

[0001] This utility model relates to the field of gas water heater performance testing technology, specifically a water heater linkage valve durability testing machine. Background Technology

[0002] The interlock valve is a core safety control component of a gas water heater. Its function is to synchronously control the gas supply and water flow regulation when the water heater is started, turned off, or when water / gas pressure fluctuates, ensuring safe use. The durability of the interlock valve directly affects the service life of the water heater and user safety; therefore, its reliability must be verified through repeated opening and closing tests.

[0003] Traditional methods rely on manual valve operation, resulting in low testing frequency, long testing cycles, and high labor costs. Manual operation makes it difficult to ensure that the pressure, flow rate, and opening and closing speed are completely consistent for each test, leading to large fluctuations in test data and an inability to accurately simulate actual usage scenarios. Therefore, we have proposed a water heater linkage valve durability testing machine to solve the above-mentioned problems. Utility Model Content

[0031] like Figure 1-3 As shown:

[0032] A durability testing machine for water heater linkage valves, including a test bench 101;

[0033] The main body 103 of the water heater linkage valve is set on the test bench 101. A placement rack 102 is fixedly installed on the upper surface of the test bench 101 near the position of the main body 103 of the water heater linkage valve. The main body 103 of the water heater linkage valve can be installed on the placement rack 102.

[0034] L-shaped plate 104 is set on test bench 101;

[0035] The first moving mechanism 2 is installed on the test bench 101 and drives the L-shaped plate 104 to move laterally. The first moving mechanism 2 includes an L-shaped base plate 201 fixed to the upper surface of the test bench 101 and slide rails 202 symmetrically arranged on the upper surface of the L-shaped base plate 201. A second telescopic cylinder 205 is fixedly installed on one side of the L-shaped base plate 201. An installation plate 204 is fixedly installed at the output end of the second telescopic cylinder 205. A movable seat 203 that can slide at the upper limit of the slide rails 202 is fixedly installed at the bottom of the installation plate 204. The bottom of the L-shaped plate 104 is fixedly installed on the upper surface of the installation plate 204.

[0036] Mounting base 105 is located above L-shaped plate 104, and a rotating cylinder 106 is rotatably mounted in the mounting base 105 via bearings. One end of the rotating cylinder 106 is provided with multiple sets of clamps 107 arranged in a ring at equal intervals, which correspond to the piezoelectric valve of the water heater linkage valve body 103.

[0037] The second moving mechanism 3 is mounted on the L-shaped plate 104 and is used to drive the mounting base 105 to move laterally. The second moving mechanism 3 includes a third telescopic cylinder 303 fixed to one side of the L-shaped plate 104. The output end of the third telescopic cylinder 303 is connected to the mounting base 105. A side plate is fixedly mounted on the upper surface of the L-shaped plate 104, and a second guide rod 301 arranged symmetrically is fixed between the side plate and the L-shaped plate 104. A sliding sleeve 302 that can slide on the second guide rod 301 is fixedly mounted on the lower surface of the mounting base 105.

[0038] Rotating mechanism 4, located between mounting base 105 and rotating cylinder 106, is used to drive rotating cylinder 106 to rotate. Rotating mechanism 4 includes a servo motor 401 fixedly mounted on a plate, a first gear 402 fixedly mounted on the output end of servo motor 401, a second gear 403 fixedly mounted on the outer surface of rotating cylinder 106, and a gear belt 404 meshing between the second gear 403 and the first gear 402.

[0039] A ring spring 108 is sleeved on one end of a set of grippers 107. A hinge seat is fixedly installed on the surface of the rotating cylinder 106 near the position of the set of grippers 107. The grippers 107 are hinged to the hinge seat through a hinge shaft. A rectangular opening adapted to the grippers 107 is opened on the surface of the rotating cylinder 106. A limiting groove adapted to the ring spring 108 is opened at one end of the grippers 107. The ring spring 108 is sleeved in the limiting groove opened in the grippers 107.

[0040] The connecting rod 109 is mounted on the L-shaped plate 104, and a tapered seat 110 is fixedly mounted on one end;

[0041] The pressing plate 111 is installed at one end of the rotating cylinder 106 and is located at the center of the multiple sets of grippers 107;

[0042] The first telescopic cylinder 113 is located on one side of the rotating cylinder 106, and a pressing head 114 corresponding to the piezoelectric igniter of the water heater linkage valve body 103 is fixedly installed at one end. A support plate 112 is fixedly installed on the upper surface of the test bench 101 near the position of the first telescopic cylinder 113, and the first telescopic cylinder 113 is fixedly installed on the support plate 112.

[0043] The end of the gripper 107 is fitted with a silicone sleeve 115, and an anti-detachment hook 116 is fixedly installed on the side of the gripper 107 near the silicone sleeve 115 by screws.

[0044] In this embodiment: When using the water heater linkage valve durability testing machine of the present invention, the water heater linkage valve body 103 can be firmly fixed on the placement frame 102 by means of screws or binding. During this installation process, the piezoelectric igniter on the water heater linkage valve body 103 corresponds to the output end pressing head 114 of the first telescopic cylinder 113, while the piezoelectric valve of the linkage valve corresponds to the clamp 107 and the pressing plate 111.

[0045] During testing, by activating the first telescopic cylinder 113 on the support plate 112, the pressing head 114 can be driven to move, thereby periodically pressing the piezoelectric igniter on the water heater linkage valve body 103.

[0046] Activating the second telescopic cylinder 205 will cause the mounting plate 204 to slide on the slide rail 202 via the movable seat 203. As the mounting plate 204 moves, the L-shaped plate 104, mounting seat 105, rotating cylinder 106, and pressing plate 111 will move synchronously. During this process, the ring spring 108 is in an elastic tension state, applying downward pressure to one end of the gripper 107, causing the gripper 107 to fold around the hinge axis at an angle, thus entering the open state. The opening diameter of the gripper 107 is larger than the diameter of the piezoelectric valve of the water heater linkage valve body 103. At this time, the pressing plate 111 contacts the piezoelectric valve, and the pressing test of the piezoelectric valve is achieved by the action of the pressing plate 111.

[0047] After the pressing operation is completed, the second telescopic cylinder 205 drives the mounting plate 204 and other components to reset. At the same time, the third telescopic cylinder 303 starts, driving the mounting base 105 to move. The mounting base 105 slides in the sliding sleeve 302 on the second guide rod 301, and at the same time drives the rotating cylinder 106 and pressing plate 111 and other components to move laterally. During the movement of the rotating cylinder 106, the gripper 107 also moves synchronously. The rotating cylinder 106 is provided with a conical seat 110. The gripper 107 is blocked by the conical seat 110, generating a relative squeezing force, which causes the gripper 107 to be folded at an angle through the hinge shaft. One end of the three sets of grippers 107 folds inward, thereby clamping the piezoelectric valve on the water heater linkage valve body 103.

[0048] During continued operation, the servo motor 401 is started, driving the first gear 402 to rotate. The first gear 402 meshes with the second gear 403 through the gear belt 404, thereby driving the second gear 403 to rotate. The rotation of the second gear 403 causes the rotating cylinder 106 to rotate on the mounting base 105, and at the same time drives multiple sets of grippers 107 to rotate synchronously, thereby performing a counterclockwise rotation test on the piezoelectric valve on the water heater linkage valve body 103. By reversing the servo motor 401, the piezoelectric valve can be rotated clockwise to the starting point, thus realizing flexible vertical installation and rotation test in both directions.

[0049] The clamping end of the gripper 107 is fitted with a silicone sleeve 115. The silicone sleeve 115 can effectively prevent damage when clamping and turning the pressure valve of the water heater linkage valve body 103, and further improve the durability of the structure.

[0050] In addition, the clamping end of the gripper 107 is equipped with an anti-disengagement hook 116. While clamping, the inner wall of the anti-disengagement hook 116 contacts the outer side of the pressure valve to form a physical lock, reducing the possibility of slippage or disengagement, thereby improving the stability of screwing.

[0051] This solution achieves high-frequency testing through mechanically driven grippers 107 and actuators. Compared with manual operation, it significantly shortens the testing cycle. The fully automatic operation mode requires no manual supervision and can conduct continuous testing. The automatic control drive system ensures the consistency of each test, reduces the volatility of test data, helps to more accurately simulate actual use scenarios, and improves the reliability of test results.

[0052] It should be noted that: This product has a touch screen installed on the rod, which can display test data in real time. All the contents of this structure that are not described in detail are existing technologies known to those skilled in the art.

[0053] Meanwhile, all the electrical equipment involved is powered by an external power source. The solution also includes a controller, which is installed on the test bench 101. During use, each piece of electrical equipment can be started and operated separately through the electrical control cabinet. The power connection method of each piece of electrical equipment is an existing mature technology and is well known to those in the field, so it will not be elaborated further here.

[0054] The working principle and usage process of this utility model are as follows: When using the water heater linkage valve durability testing machine of this invention, the water heater linkage valve body 103 is fixed to the placement frame 102 by screws or binding. The piezoelectric igniter on the water heater linkage valve body 103 corresponds to the pressing head 114 of the first telescopic cylinder 113. The piezoelectric valve corresponds to the gripper 107 and the pressing plate 111. The first telescopic cylinder 113 is activated, driving the pressing head 114 to move and periodically pressing the piezoelectric igniter on the water heater linkage valve body 103. The second telescopic cylinder 205 is activated, driving the installed... Plate 204 slides on slide rail 202, causing L-shaped plate 104, mounting base 105, rotating cylinder 106, and pressing plate 111 to move synchronously. Ring spring 108 applies pressure to gripper 107, causing it to open. The opening diameter of gripper 107 is larger than the diameter of the piezoelectric valve in the water heater linkage valve body 103. At this time, pressing plate 111 contacts the piezoelectric valve, and the pressing operation of pressing plate 111 performs a pressing test on the piezoelectric valve. After the pressing operation is completed, second telescopic cylinder 205 drives mounting plate 204 and other components to reset. Simultaneously, third telescopic cylinder 303 starts, driving mounting base 105 to move. When the mounting base 105 slides within the sliding sleeve 302 on the second guide rod 301, it simultaneously drives the rotating cylinder 106 and pressing plate 111 to move laterally. During the movement of the rotating cylinder 106, the grippers 107 also move synchronously. The rotating cylinder 106 has a conical seat 110 inside, and the grippers 107 are blocked by the conical seat 110, generating a relative squeezing force. This causes the grippers 107 to fold at an angle via the hinge shaft, with one end of the three sets of grippers 107 folding inward, thereby clamping the piezoelectric valve on the water heater linkage valve body 103. During continued operation, the servo motor is activated. The servo motor 401 drives the first gear 402 to rotate. The first gear 402 meshes with the second gear 403 through the gear belt 404, thereby driving the second gear 403 to rotate. The rotation of the second gear 403 causes the rotating cylinder 106 to rotate on the mounting base 105, and at the same time drives multiple sets of grippers 107 to rotate synchronously, thereby performing a counterclockwise 60-degree rotation test on the piezoelectric valve on the water heater linkage valve body 103. By reversing the servo motor 401, the piezoelectric valve can be rotated clockwise to the starting point, thereby realizing flexible vertical installation and rotation test in both directions.

[0055] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
