Description

Technical Field

[0001] This utility model relates to the field of impact testing machine technology, and in particular to a pendulum impact testing machine for valves. Background Technology

[0002] A pendulum impact testing machine for valves is a device used to test the impact resistance of valves, designed to simulate sudden impacts or pressure fluctuations that valves may encounter in actual operation. Valves are widely used in industries such as petroleum, natural gas, and power, and their performance directly affects the safety of the system. Because valves often face complex environments such as high pressure, temperature changes, and external impacts, impact forces can lead to valve seal failure or structural damage. Therefore, evaluating the impact resistance of valves is crucial. This testing machine applies impact energy of a specific intensity to test the structural strength and sealing performance of the valve, ensuring its stable operation even under extreme conditions.

[0003] However, when using a pendulum impact testing machine for valves, there are sometimes situations where it is inconvenient to replace the hammer head when it is necessary to change to a different model to obtain more accurate measurement data. This results in more time being spent on disassembling and assembling the hammer head, which in turn affects the use of subsequent devices. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a pendulum impact testing machine for valves.

[0005] This utility model is achieved by the following technical solution: a pendulum impact testing machine for valves, comprising a connecting mechanism, a fixing mechanism and a supporting mechanism, wherein the connecting mechanism is located at the upper end of the fixing mechanism and the fixing mechanism is located at the upper end of the supporting mechanism;

[0006] The connecting mechanism includes a connecting frame, a sliding frame slidably connected to the inner wall of the connecting frame, a pressure block fixedly connected to the front end of the sliding frame, a snap-fit ​​shaft fixedly connected to the inner wall of the sliding frame, a limit rod fixedly connected to the rear end of the sliding frame, a spring sleeved on the surface of the limit rod, a support plate fixedly connected to the inner wall of the connecting frame, a connecting plate snapped onto the surface of the snap-fit ​​shaft, an impact hammer fixedly connected to the right end of the connecting plate, a pressure block slidably connected to the inner wall of the connecting frame, a limit rod slidably connected to the inner wall of the support plate, a spring located between the sliding frame and the support plate, a left end of the connecting frame fixedly connected to the right end of the rotating arm, and a connecting plate slidably connected to the inner wall of the connecting frame.

[0007] The above technical solution uses a fixed connecting plate on the surface of the impact hammer and a sliding bracket to control the locking shaft to limit the connection plate, which makes it easier to replace the impact hammer and further improves the overall practicality of the device.

[0008] As a further improvement to the above solution, the fixing mechanism includes a fixing frame, a bidirectional screw is rotatably connected to the inner wall of the fixing frame, a knob is fixedly connected to the front end of the bidirectional screw, a sliding plate is threadedly connected to the surface of the bidirectional screw, a clamping frame is fixedly connected to the upper end of the sliding plate, the surface of the sliding plate is slidably connected to the inner wall of the fixing frame, and the knob is located at the front end of the fixing frame.

[0009] The above technical solution uses a rotating bidirectional screw to drive the clamping frames on both sides to clamp the valve in the middle, which achieves the purpose of conveniently adapting to and clamping valves of different sizes, making subsequent testing work more convenient.

[0010] As a further improvement to the above solution, the support mechanism includes a support base, a support frame fixedly connected to the upper end of the support base, a dial fixedly connected to the upper end of the support frame, a rotating arm rotatably connected to the front end of the dial, a limit plate slidably connected to the inner wall of the dial, the upper end of the limit plate contacting the lower end of the rotating arm, and the upper end of the support base being fixedly connected to the lower end of the fixed frame.

[0011] The above technical solution provides a stable connection and support for the overall device, making the use of subsequent devices more convenient.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model, through the setting of a connecting mechanism, specifically: when it is necessary to change the model of the impact hammer to obtain more comprehensive test data, the pressure block is first pressed, thereby driving the sliding frame and the locking shaft to slide backward, thus separating the locking shaft from the connecting plate, thereby releasing the limitation on the connecting plate. At this time, the connecting plate and the impact hammer can be removed together. Then, the impact hammer to be replaced, along with the new connecting plate, is inserted back in. Then, the pressure block is released, and the sliding frame, freed from its limitation, is driven back by the action of the rear spring, thereby driving the locking shaft to re-insert into the inner wall of the connecting plate and limit it, so as to facilitate subsequent testing. The design of using the connecting plate fixed on the surface of the impact hammer and using the sliding of the sliding frame to control the locking shaft to limit the connecting plate achieves the purpose of making it more convenient when the impact hammer needs to be replaced, thereby further improving the overall practicality of the device.

[0014] This utility model employs a fixing mechanism: the valve to be tested is placed between two clamping frames, and then a knob is rotated to drive a bidirectional screw to rotate. Simultaneously, a sliding plate on the surface of the bidirectional screw slides on the surface of the fixing frame under its constraint, thereby driving the upper clamping frame to clamp and fix the valve in the middle, preventing the valve from loosening during subsequent testing. The design of using the rotating bidirectional screw to drive the two clamping frames to clamp the valve in the middle achieves the purpose of conveniently adapting to and clamping valves of different sizes, making subsequent testing work more convenient.

[0023] Example:

[0024] Please combine Figure 1-5 The present embodiment of a pendulum impact testing machine for valves includes a connecting mechanism 1, a fixing mechanism 2 and a supporting mechanism 3. The connecting mechanism 1 is located at the upper end of the fixing mechanism 2, and the fixing mechanism 2 is located at the upper end of the supporting mechanism 3.

[0025] The connecting mechanism 1 includes a connecting frame 101, a sliding frame 102 slidably connected to the inner wall of the connecting frame 101, a pressure block 103 fixedly connected to the front end of the sliding frame 102, a snap-fit ​​shaft 104 fixedly connected to the inner wall of the sliding frame 102, a limit rod 105 fixedly connected to the rear end of the sliding frame 102, a spring 106 sleeved on the surface of the limit rod 105, a support plate 107 fixedly connected to the inner wall of the connecting frame 101, a connecting plate 108 snapped onto the surface of the snap-fit ​​shaft 104, and an impact hammer 109 fixedly connected to the right end of the connecting plate 108. The design of using the fixed connecting plate 108 on the surface of the impact hammer 109 and the sliding of the sliding frame 102 to control the snap-fit ​​shaft 104 to limit the connecting plate 108 is designed to make it more convenient to replace the impact hammer 109, thereby further improving the overall practicality of the device.

[0026] The surface of the pressure block 103 is slidably connected to the inner wall of the connecting frame 101, the surface of the limiting rod 105 is slidably connected to the inner wall of the support plate 107, and the spring 106 is located between the sliding frame 102 and the support plate 107.

[0027] The fixing mechanism 2 includes a fixing frame 201. A bidirectional screw 202 is rotatably connected to the inner wall of the fixing frame 201. A knob 203 is fixedly connected to the front end of the bidirectional screw 202. A sliding plate 204 is threadedly connected to the surface of the bidirectional screw 202. A clamping frame 205 is fixedly connected to the upper end of the sliding plate 204. The design of using the rotation of the bidirectional screw 202 to drive the clamping frames 205 on both sides to clamp the middle valve achieves the purpose of conveniently adapting to and clamping valves of different sizes, making subsequent testing work more convenient.

[0028] The surface of the sliding plate 204 is slidably connected to the inner wall of the fixed frame 201, and the knob 203 is located at the front end of the fixed frame 201.

[0029] The support mechanism 3 includes a support base 301, a support frame 302 is fixedly connected to the upper end of the support base 301, a dial 303 is fixedly connected to the upper end of the support frame 302, a rotating arm 304 is rotatably connected to the front end of the dial 303, and a limit plate 305 is slidably connected to the inner wall of the dial 303.

[0030] The upper end of the limiting plate 305 contacts the lower end of the rotating arm 304, and the upper end of the support base 301 is fixedly connected to the lower end of the fixing frame 201.

[0031] The left end of the connecting frame 101 is fixedly connected to the right end of the rotating arm 304, and the surface of the connecting plate 108 is slidably connected to the inner wall of the connecting frame 101.

[0032] The implementation principle of a pendulum impact testing machine for valves in this embodiment is as follows: When using the device, the valve to be tested is first placed between the two clamping frames 205. Then, the knob 203 is rotated to drive the bidirectional screw 202 to rotate. At the same time, the sliding plate 204 on the surface of the bidirectional screw 202 slides on the surface of the fixed frame 201 under the restriction of the fixed frame 201, thereby driving the upper clamping frame 205 to clamp and fix the valve in the middle to prevent the valve from loosening during subsequent testing. The design of using the rotation of the bidirectional screw 202 to drive the two clamping frames 205 to clamp the valve in the middle achieves the purpose of conveniently adapting to and clamping valves of different sizes, making subsequent testing work more convenient. After the valve is fixed, the limiting plate 305 is pulled back to separate it from the rotating arm 304. At this time, the rotating arm 304, supported by the limiting plate 305, drives the impact hammer 109 to swing downward in a circular motion under the action of gravity, thereby performing an impact test on the lower valve. When replacing model 109 to obtain more comprehensive test data, first press down on pressure block 103 to drive sliding bracket 102 and locking shaft 104 backward, thereby separating locking shaft 104 from connecting plate 108 and releasing the limiting effect on connecting plate 108. At this point, connecting plate 108 and impact hammer 109 can be removed together. Then, insert the replacement impact hammer 109 and the new connecting plate 108 back in, and then release the pressure block 103. At this point, sliding bracket 109... 2. After losing its restraint, the spring 106 at the rear end causes it to spring back again, thereby driving the snap-fit ​​shaft 104 to re-insert into the inner wall of the connecting plate 108 and limit it, so as to facilitate subsequent testing. The design of using the connecting plate 108 fixed on the surface of the impact hammer 109 and the sliding of the sliding bracket 102 to control the snap-fit ​​shaft 104 to limit the connecting plate 108 achieves the purpose of making it more convenient to replace the impact hammer 109, thereby further improving the overall practicality of the device.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
