Technical Field

[0001] The utility model relates to the technical field of safety valves, in particular to a safety valve inspection clamping mechanism. Background Art

[0002] A safety valve is a special valve whose opening and closing parts are in a normally closed state under the action of external force. When the medium pressure in the equipment or pipeline rises above the specified value, the medium is discharged to the outside of the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value. The safety valve is an automatic valve and is mainly used in boilers, pressure vessels and pipelines to control the pressure not to exceed the specified value. It plays an important protective role in personal safety and equipment operation. The safety valve must pass the pipeline safety valve inspection bench pressure test before it can be used.

[0003] When the existing pipeline safety valve inspection bench is idle, it is not easy to protect the instruments and electrical components on the surface. Instead, it is directly exposed to the air and is affected by dust and water vapor for a long time, which can easily cause corrosion and damage to the surface of the instruments and electrical components, shortening their service life. Therefore, a safety valve inspection clamping mechanism is proposed.

[0004] The cam is fixed on the upper end of the cam and is fixed with the guide rail, and the cam is fixed with the guide rail at the bottom end thereof.

[0005] Although the above patent has achieved the goal of pushing the push rod through the inspection door on the pipeline safety valve inspection platform through the arrangement of the upper cover plate, guide rod, impact plate, push rod, extension plate and clamping block, when in use, the push rod can drive the upper cover plate to move upward through the guide rod, so that the cover plate extends out to prevent it from hitting the head of the maintenance personnel and improve safety; however, the device is not easy to perform anti-pull treatment on the wiring port, and the wiring port is easily loosened by external force, affecting the normal use of the equipment.
