[0001] This utility model relates to the field of breather valve calibration technology, specifically a breather valve calibration device for storage tanks. Background Technology

[0002] In the manufacturing of breather valves for storage tanks, to prevent safety accidents caused by overpressure or vacuum conditions and to reduce media evaporation losses, a breather valve calibration device is often used to test the performance of the breather valve after it has been manufactured. This verifies whether the opening pressure of the breather valve under positive and negative pressure conditions meets national standards, thus ensuring the safety and sealing of the storage tank.

[0003] Before using existing tank breather valve calibration devices, the workpiece to be processed usually needs to be placed on the calibration table. However, in actual inspection, the connection between the breather valve and the calibration equipment is unstable. This problem can easily lead to air leakage at the connection, which is not conducive to the normal operation of the device. Therefore, a tank breather valve calibration device is proposed to address the above problems. Utility Model Content

A first spring and a second spring are fixedly connected to both sides of the limiting slider. An electric actuator is fixedly installed in a groove on the inner side of the limiting slider. A limiting pressure member is fixedly connected to the movable end of the electric actuator. A limiting column is fixedly connected to the bottom of the limiting slider. A sealing gasket is fixedly installed in an annular groove located on the upper inner side of the limiting support.

[0007] Preferably, an operating platform is fixedly connected to the top rear position of the sealed square tank, and a display panel is fixedly installed on the front right side of the operating platform, with the display panel tilted forward.

[0008] Preferably, an air pump is connected to the upper right front end of the sealed square tank, and an air pump is connected to the upper right rear end of the sealed square tank, with the air pump and the air pump arranged in a front-to-back arrangement.

[0009] Preferably, the connection between the limiting support and the sealed square can is provided with a solenoid valve that is configured to conduct, and a sealing joint is connected above the solenoid valve, the sealing joint extending and inserting into the interior of the breather valve body.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution:

[0019] A breather valve calibration device for a storage tank includes a sealed square tank 1. A limiting support 2 is fixedly connected to the top left of the sealed square tank 1. A breather valve body 3 is placed directly above the limiting support 2. A side guide rail 4 is fixedly connected to the outside of the limiting support 2. A vertical plate 5 is fixedly connected to the bottom of the side guide rail 4. A limiting slider 6 is slidably connected inside the side guide rail 4. A first spring 7 and a second spring 8 are fixedly connected to both sides of the limiting slider 6. An electric push rod 9 is fixedly installed in the groove inside the limiting slider 6. A limiting pressure member 10 is fixedly connected to the movable end of the electric push rod 9. A limiting column 11 is fixedly connected to the bottom of the limiting slider 6. A sealing gasket 18 is fixedly installed in the annular groove provided on the upper inner side of the limiting support 2.

[0020] An operating platform 14 is fixedly connected to the top rear of the sealed square tank 1. A display panel 15 is fixedly installed on the front right side of the operating platform 14. The display panel 15 is tilted forward, which helps the operator to see the verification data displayed on the display panel 15 more clearly. An air pump 16 is connected to the upper right front end of the sealed square tank 1, and an air pump 17 is connected to the upper right rear end of the sealed square tank 1. The air pump 17 and the air pump 16 are arranged in a front-to-back arrangement, which allows the device to complete the entire verification work by air filling and air emptying respectively. A solenoid valve 12 is provided at the connection between the limiting support 2 and the sealed square tank 1. A sealing connector 13 is connected to the upper part of 12. The sealing connector 13 extends and is inserted into the interior of the breathing valve body 3. The sealing connector 13 serves to assist in connecting the sealing square can 1 and the breathing valve body 3. Four limiting pressure members 10 are arranged in a ring array along the center point of the limiting support 2. The upper end surface of the limiting pressure member 10 is inclined. The limiting column 11 and the side guide rail 4 are slidably connected by a groove on the bottom surface. The limiting column 11 has an inverted "T" shape. The first spring 7 and the second spring 8 are fixedly connected to the inner side of the side guide rail 4. When the limiting slider 6 moves horizontally, the limiting column 11 plays a guiding and auxiliary limiting role.

[0021] Workflow: The electrical energy required for the start-up and operation of the device in this utility model comes from an external power source. During the manufacturing and processing of the tank breather valve, when using this calibration device to inspect the breather valve body 3, align the top surface of the limiting support 2 and place the breather valve body 3 from top to bottom. During this process, the breather valve body 3 will be centered along the inclined surfaces of multiple limiting pressure members 10. When it is placed at a certain height, the multiple limiting pressure members 10 are squeezed, causing them to unfold outward. The first spring 7 and the second spring 8 deform. After the bottom of the breather valve body 3 passes through the limiting space formed by the multiple limiting pressure members 10, the breather valve body 3 will fit against the top surface of the sealing gasket 18, and the sealing joint 13 will also fit into the breather valve body 3. At the same time, the first spring 7 and the second spring 8... 8. The reset and rebound mechanism begins. The limiting slider 6, along with the electric push rod 9 and the limiting pressure piece 10, moves towards the center position to achieve reset. Once in place, multiple electric push rods 9 are activated to pull downwards, and multiple limiting pressure pieces 10 then fix the lower base of the breathing valve body 3, ensuring a tight fit between the breathing valve body 3 and the sealing gasket 18. This increases the stability of the breathing valve body 3 after connection with the sealing joint 13. Then, the inflation pump 17 is activated to inflate the sealed container 1. The gas is then sent into the breathing valve body 3 through the sealing joint 13, and the pressure data under inflation conditions is obtained. Next, the vacuum pump 16 is activated to vacuum the valve, and the pressure data under vacuum conditions is obtained. This allows subsequent devices to compare the data differences to complete the inspection of a single breathing valve body 3.
