Technical Field

[0001] The utility model relates to the technical field of sealing valve detection, and more specifically to a sealing performance detection device for an active sealing valve. Background Art

[0002] A sealing valve is a device used to control the flow of fluids (such as water, gas, oil, etc.) through pipelines. It can adjust and control parameters such as flow, pressure, and temperature. After the sealing valve is produced, it is necessary to use a detection device to detect the sealing performance of the sealing valve to ensure that the sealing performance of the sealing valve meets the use requirements.

[0003] Based on the above, the inventors found that when the existing detection device is in use, it needs to be fixed by bolts passing through the flanges at both ends of the valve body. The operation is relatively cumbersome, which affects the detection efficiency of the sealing valve. Therefore, in view of this, the existing structure is studied and improved to provide a sealing performance detection device for an active sealing valve, in order to achieve a more practical purpose.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] Example:

[0027] See also Figure 1-4 A sealing performance testing device for an active sealing valve includes an air pump 1 and a base 2. A limit sleeve 4 is provided on both ends of the top surface of the base 2, and a driving motor 3 is fixedly connected to one end of the base 2. A valve body 5 is centrally provided on the opposite surfaces of the two limit sleeves 4. A set of flange grooves 6 are provided at both ends of the valve body 5. A bidirectional screw rod 7 is fixedly connected to the output end of the driving motor 3. A pair of ball sliders 8 are provided on the outer side of the bidirectional screw rod 7. A reinforcement mechanism 9 is provided on the outer side of the ball slider 8.

[0028] The reinforcement mechanism 9 includes a driven rod 11, the upper end of which is fixedly connected to a pair of reinforcement blocks 12, and an active rod 13 is symmetrically arranged on the inner side of the driven rod 11, and the inner side of the driven rod 11 and the inner side of the active rod 13 are fixedly connected to a tooth plate 14, and the opposite surfaces of the two tooth plates 14 are centrally meshed and connected with a tooth ring 15. In order to improve the stability of the valve body 5 and ensure the smooth progress of the detection work, a reinforcement mechanism 9 is provided.

[0029] See Figure 1 The air pump 1 is located on one side of the base 2, and the output end of the air pump 1 is fixedly connected to the limiting sleeve 4 of the two limiting sleeves 4 close to the air pump 1. Start the air pump 1 to deliver air to the corresponding limiting sleeve 4, and the air impacts the valve body 5.

[0030] See Figure 3The bidirectional screw rod 7 and the ball slider 8 are both located in the center of the base 2, and the bidirectional screw rod 7 is movably connected to the base 2, and the ball slider 8 is slidably connected to the base 2. The valve body 5 is placed between the two limit sleeves 4, and the drive motor 3 is started to drive the bidirectional screw rod 7 to rotate. The bidirectional screw rod 7 cooperates with the two ball sliders 8 to make the two limit sleeves 4 slide synchronously in opposite directions. The two limit sleeves 4 are respectively engaged with the two ends of the valve body 5 to limit and fix the valve body 5.

[0031] See Figure 3 The top of the ball slider 8 passes through the base 2 and is fixedly connected to the limit sleeve 4. The outer side of the limit sleeve 4 away from the air pump 1 of the two limit sleeves 4 is fixedly connected with a pressure gauge 10. If a leakage problem occurs, the air flow passes through the valve body 5 and enters the interior of the limit sleeve 4 away from the air pump 1, and the value of the pressure gauge 10 changes. On the contrary, if the sealing of the valve body 5 meets the use requirements, the value of the pressure gauge 10 does not change.

[0032] See Figure 4 The active rod 13 and the driven rod 11 are both slidably connected to the base 2, and the top of the active rod 13 is fixedly connected to the outer side of the limiting sleeve 4. When the limiting sleeve 4 limits the valve body 5, it drives the active rod 13 to move synchronously.

[0033] See Figure 4 The toothed plate 14 on the inside of the active rod 13 penetrates the driven rod 11, and the toothed plate 14 on the inside of the driven rod 11 penetrates the active rod 13. Then, the two oppositely arranged toothed plates 14 cooperate with the gear ring 15 to make the driven rod 11 move in the opposite direction synchronously.

[0034] See Figure 4 The gear ring 15 is movably connected to the base 2, the reinforcement block 12 is clamped with the flange groove 6, and the driven rod 11 drives the reinforcement block 12 to move and clamp with the flange groove 6 on the valve body 5 to reinforce the valve body 5.

[0035] When the valve body 5 is limited, the active rod 13 is driven to move synchronously, and then the two oppositely arranged tooth plates 14 cooperate with the tooth ring 15 to make the driven rod 11 move synchronously in the opposite direction. The driven rod 11 drives the reinforcement block 12 to move and engage with the flange groove 6 on the valve body 5 to reinforce the valve body 5. Then, the air pump 1 is started to supply air to the corresponding limit sleeve 4. The air impacts the valve body 5. If a leakage problem occurs, the air flow passes through the valve body 5 and enters the inside of the limit sleeve 4 away from the air pump 1, and the pressure gauge 10 changes value. On the contrary, if the sealing of the valve body 5 meets the use requirements, the pressure gauge 10 does not change value, and the sealing performance test of the valve body 5 is completed.
