Description

Technical Field

[0001] The utility model relates to the technical field of safety valve detection, in particular to a device for checking the flatness of a safety valve flap. Background Art

[0002] A safety valve is a closing member that is normally closed under the action of an external force. When the pressure of the medium in a device or pipeline rises above a specified value, it is a special valve that prevents the medium pressure in the pipeline or device from exceeding the specified value by discharging the medium to the outside of the system. It is mainly used on boilers, pressure vessels and pipelines to control the pressure not to exceed the specified value. If the sealing surface is uneven or bent, etc., it will cause uneven sealing pressure around, resulting in leakage. Therefore, the stability and reliability of its performance are crucial for protecting the safety of equipment and personnel. The inspection of flatness, as part of the safety valve inspection, aims to ensure that the performance of the safety valve meets the design and use requirements. Through flatness measurement, problems with the material can be detected in a timely manner, and corresponding measures can be taken to ensure the quality of the product.

[0003] Patent Publication No.: CN209978842U provides a device for detecting the flatness of the surface of a valve, including a support base, four support rods and an installation box. The support rods are fixedly connected to the top of the support base, and the installation box is fixedly connected to the four support rods. The installation box is provided with an installation frame, a bidirectional threaded rod and a supplementary light. The bidirectional threaded rod is provided with a connecting rod and a first rotating handle. The installation frame is provided with a second rotating handle. A push rod motor is arranged on the support base. The safety valve is clamped through the cooperation of the push rod motor and the bidirectional threaded rod, and the surface of the safety valve is illuminated by the supplementary light, and then manually inspected. However, when the above patent is used, personnel need to use the rotating handle to rotate the clamped safety valve. When the personnel rotate the safety valve, their eyes have to constantly observe the surface of the safety valve. During the operation, it is necessary to check the safety valve and rotate the safety valve at the same time, which is inconvenient.

[0004] To solve the above problems, Patent Publication No.: CN219178544U provides a flatness detection device, including a support box body. The support box body is provided with a protective cover, a placement tray and two support brackets. The middle parts of the upper ends of the two support brackets are arc-shaped. There is a worm wheel shaft, a worm and a second motor in the support box body. The height of the safety valve is placed and adjusted through the placement tray until the two ends of the safety valve are supported by the support brackets. Finally, the safety valve is clamped and rotated through the clamping plate, and personnel can detect the flatness of the surface of the rotating safety valve. When the above patent is inspected, it is only inspected by the naked eye of personnel, and there is a problem of inaccurate inspection. Summary of the Utility Model
