Description

Sliding valve lifting appliance

Technical Field

The utility model relates to the technical field of slide valve hoisting, in particular to a slide valve hoisting tool.

Background

A lifting appliance refers to a device for lifting a heavy object in a lifting machine. The most common lifting devices for lifting finished articles are lifting hooks, lifting straps, lifting rings, lifting suction cups, clamps, forks and the like. Is widely applied to the hoisting industry. The slide valve is a flow dividing valve which utilizes a valve core (plunger piston and valve clack) to slide on a sealing surface and changes the positions of fluid inlet and outlet channels to control the flow direction of fluid. Slide valves are commonly used in steam engines, hydraulic and pneumatic devices, to allow the movement mechanism to achieve a predetermined direction and stroke of motion or to achieve automatic continuous operation. The slide valve needs to be hoisted on the die holder, but the conventional hoisting is mostly carried out by using a sling hoisting and binding method, so that the problem of complex operation is solved, and the slide valve is easily polluted after the sling rubs with the slide valve; in addition, the sling-type lifting method uses hooks that may rub against the surface of the slide valve, damaging the roughness of the slide valve surface. Moreover, the sling hoisting method cannot ensure the stability of the materials in the hoisting process, and may bring danger to field operators. Based on this, many patents have improved the hoisting method.
