Abstract

The invention relates to a safety valve gripping device. Through the gravity of the gripping device and the effect of a connecting rod mechanism, a safety valve is automatically clasped, and the safety valve is locked after being clasped; in cooperation with a hoisting device, the work of gripping the safety valve is easily completed; the safety valve is manually unlocked to be loosened after being placed at a specified station; and one gripping action can be completed within 10 seconds. The safety valve is automatically clasped through the gravity of the device and the movement effect of theconnecting rod mechanism without depending on applied driving force, the safety valve is locked through the mutual effect of a locking nut, a guide rod and a lifting rod and cannot be automatically unlocked, and thus it is avoided that the safety valve falls off due to vibration in the hoisting process. The safety valve gripping device is high in universality, and safety valves of different specifications can be gripped only by adjusting the connection positions of supporting rods, clasping arms and connecting rods. When the safety valve is taken down from equipment using the safety valve through the gripping device, personnel can keep away from the safety valve, and it is avoided that diffusion of residual media at the bottom of the safety valve does harm to the health of the personnel.

Description

technical field [0001] The invention belongs to an auxiliary tooling, in particular to a grabbing device for a safety valve. Background technique [0002] The safety valve is an automatic valve installed on the pressure-bearing equipment. When the pressure of the medium in the equipment rises above the specified value, the safety valve opens and the medium is discharged to the outside, so as to prevent the occurrence of safety accidents caused by the pressure of the medium in the equipment exceeding the specified value. . Widely used in boilers, pressure vessels and pressure pipelines in petroleum, power station, metallurgy, machinery, electronics, mining, chemical industry, building materials, electric power, energy and other industries, the control pressure does not exceed the specified value, which plays an important role in the protection of personal safety and equipment operation effect.
