[0022] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely examples. The electric water valve durability testing machine involved in the present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] The utility model provides an electric water valve durability testing machine, comprising a base 1, a water tank 2 and a water pump 3 are slidably mounted on the top of the base 1, a support frame 4 is fixedly connected to the top of the base 1, a positioning mechanism 5 is mounted on the top of the support frame 4, a connecting pipe 21 is fixedly connected to the top of the water tank 2, and a guide pipe 31 is fixedly connected to the output end of the water pump 3.

[0024] The positioning mechanism 5 includes a fixing frame 51, a clamping assembly 52 and a rotating rod 53. The fixing frame 51 is fixedly connected to the top of the support frame 4. Two clamping assemblies 52 are symmetrically arranged. The clamping assembly 52 includes a first arc strip 521, a second arc strip 522 and a built-in groove 523.

[0025] Furthermore, the connecting pipe 21 is connected to the inside of the water tank 2, and the connecting pipe 21 is fixedly connected to the first flange 22 at one end away from the water tank 2, and the guide pipe 31 is fixedly connected to the second flange 32 at one end away from the water pump 3. A pressure gauge 33 is fixedly installed on the top of the guide pipe 31, and the pressure gauge 33 is used to monitor the water pressure before entering the electric water valve. The first flange 22 is used to be connected to the output end flange of the electric water valve, and the second flange 32 is used to be connected to the input end flange of the electric water valve.

[0026] Furthermore, a handle 23 is fixedly connected to one side of the water tank 2, and the water tank 2 and the input end of the water pump 3 are fixedly connected via a hose 34. A guide bar 11 is fixedly connected to the top of the base 1, and a group of guide bars 11 are provided. Guide grooves are provided at the bottom of the water tank 2 and the bottom of the water pump 3. The guide bars 11 and the guide grooves form a sliding guide cooperation. The staff can push and pull the water tank 2 to slide along the guide bar 11 through the handle 23, and can also push and pull the water pump 3 to slide along the guide bar 11, thereby realizing the movement of the position of the first flange 22 and the second flange 32, which is simple and convenient to operate.

[0027] Furthermore, an avoidance hole 41 is opened through the support frame 4, and there are two avoidance holes 41. A control panel 42 is also fixedly installed on the support frame 4. The control panel 42 is electrically connected to the water pump 3 through an electric wire 43. The avoidance hole 41 is used to pass through the connecting pipe 21 and the guide pipe 31. The staff can send instructions to the water pump 3 through the control panel 42 to realize the start of the water pump 3 and the change of power.

[0028] Furthermore, the first curved bar 521 is fixedly connected to the top of the fixing frame 51, and the bottom of the second curved bar 522 is fixedly connected to a moving block 525. The built-in groove 523 is opened at the top of the fixing frame 51, and the moving block 525 is located in the built-in groove 523, and the surface of the moving block 525 is slidably connected to the groove wall of the built-in groove 523. A threaded rod 524 is rotatably installed in the built-in groove 523, and one end of the threaded rod 524 passes through the groove wall of the built-in groove 523 and extends outward. The interior of the moving block 525 is threadedly connected to the surface of the threaded rod 524, and one end of the threaded rod 524 is fixedly connected to the second bevel gear 526. A first bevel gear 531 is fixedly connected to each end of the rotating rod 53, and the first bevel gear 531 is meshed with the second bevel gear 526. Then, a rotating handle 54 is fixedly connected to the center of the surface of the rotating rod 53, and a supporting frame 55 is fixedly connected to the fixed frame 51. The rotating rod 53 and the supporting frame 55 are rotatably connected, and the supporting frame 55 is used to support the rotating rod 53. The staff can pull the rotating rod 53 to rotate around its own axis by manually twisting the rotating handle 54. The first bevel gear 531 and the second bevel gear 526 cooperate with each other to convert the rotational force of the rotating rod 53 into the rotational force of the threaded rod 524. When the threaded rod 524 rotates, it can pull the second arc bar 522 to move in the direction close to the first arc bar 521. If the staff twists the rotating handle 54 in the opposite direction, similarly, the second arc bar 522 moves in the direction away from the first arc bar 521.

[0029] The working principle of the present utility model is as follows: during actual work, the staff places the electric water valve on the top of the fixing frame 51, and fits the electric water valve with the first curved bar 521, and then manually screws the rotating handle 54 to rotate the rotating rod 53 around its own axis. The rotating rod 53 rotates and drives the two threaded rods 524 to rotate synchronously around their own axes through the first bevel gear 531 and the second bevel gear 526. The threaded rod 524 rotates and drives the moving block 525 to slide synchronously along the built-in groove 523. The second curved bar 522 gradually moves toward the direction close to the first curved bar 521, and the electric water valve is clamped and positioned between the first curved bar 521 and the second curved bar 522.

[0030] The staff pushes the water tank 2 to slide along the guide strip 11 through the handle 23. When the water tank 2 moves, the connecting pipe 21 and the first flange 22 move synchronously. When the first flange 22 conflicts with the output end flange of the electric water valve, the staff fixes the two with bolts. The staff then pushes the water pump 3 to slide along the guide strip 11. When the water pump 3 moves, the guide pipe 31 and the second flange 32 move synchronously. When the second flange 32 conflicts with the input end flange of the electric water valve, the staff fixes the two with bolts. At this time, the installation of the electric water valve is completed.

[0031] The staff controls the water pump 3 to start through the control panel 42. The water in the water tank 2 passes through the hose 34 and the guide pipe 31 in turn and enters the electric water valve. The water then returns to the water tank 2 through the connecting pipe 21. During this process, the pressure gauge 33 monitors the water pressure in real time. If the test water pressure needs to be increased, the staff increases the output power of the water pump 3 through the control panel 42 to increase the water pressure. The staff observes whether the electric water valve leaks under different water pressures to determine the durability of the electric water valve.
