Device capable of stably clamping safety valve

Abstract

The invention discloses a device capable of stably clamping a safety valve. The device comprises a lifting platform and a safety valve clamp. The lifting platform comprises a bottom used for being mounted onto the ground and a top opposite to the bottom. The safety valve clamp is mounted on the top of the lifting platform. The safety valve clamp is used for clamping and fixing the safety valve. The safety valve clamp comprises a horizontal mounting disc and three clamping components mounted on the mounting disc and vertically arranged. The three clamping components are evenly distributed in the peripheral direction of the mounting disc. The included angle of each clamping component and the other adjacent clamping component which are connected with the center of circle of the mounting disc is 120 degrees. Each clamping component comprises a push claw capable of moving in the radius direction. Each clamping component further comprises a pressing claw for pressing the safety valve in the up-down direction. The safety valve clamp achieves clamping in multiple directions, so that clamping is more stable.

Description

technical field [0001] The invention relates to a device capable of stably clamping a safety valve, in particular to a safety valve maintenance platform with high degree of automation and multi-function integration. Background technique [0002] The safety valve is an automatic valve that uses the force of the medium itself to discharge a rated amount of fluid without any external force, so as to prevent the pressure in the system from exceeding the predetermined safety value. When the pressure returns to normal, the valve closes again and prevents the medium from continuing to flow out. Safety valves are used in pressure vessels, pressure pipes, fired boilers and other devices. They are used for explosion and damage of protected devices due to system overpressure, and play an important role in protecting equipment operation and personnel safety. [0003] After the safety valve has been used for a period of time, the sealing surface of the safety valve will be damaged to va...

AI Technical Summary

Problems solved by technology

[0007] 2. The grinding method of the sealing surface of the safety valve is manual grinding with a grinding plate, which is inefficient and labor-intensive;

[0008] For example, for a safety valve with a caliber of DN200 and serious damage to the seat sealing surface, it often takes more than 4 hours to manually grind the valve core and seat sealing surface, and an operator can only repair 2 to 3 safety valves per day at most.

[0009] 3. The quality of safety valve maintenance is often related to the proficiency of the operator, and the "one-time pass rate" of safety valve maintenance cannot be effectively improved, resulting in batch rework and seriously affecting the maintenance progress

[0010] 4. If there are large defects in the safety valve seat, special machine tools are required for machining, and special fixtures must be made to fix the valve. This method is expensive and has a long maintenance period.
