[0002] Valve is a kind of mechanical equipment widely used in oil and gas transportation. It is mainly used to control and adjust the flow of fluid in various pipelines and equipment. Commonly used valve types include gate valve, globe valve, butterfly valve, ball valve, etc.; among them, gate valve, globe valve When the valve is in use, it is usually possible to turn the valve handwheel to drive the valve stem (screw) to rotate, and then drive the valve core to move relative to the valve seat, and finally realize the opening or closing of the valve. In the process of oil and gas transportation, it is often accompanied by high pressure , when the valve is opened, due to the excessive fluid pressure, the force of the fluid on the valve plate (stem) is greater than the pressing force of the packing on the valve stem, causing the valve stem (screw) to escape, resulting in a safety accident

Embodiment Construction
[0016] figure 1 It is an axonometric drawing of the present invention, as shown in the figure, the high-pressure pipeline valve protection device of this embodiment includes a protection wheel that can be coaxially connected to the outer end of the valve handwheel and can drive the valve handwheel to rotate synchronously; the protection wheel The center of the circle is fixed with a protective shell 4 used to prevent the valve screw from popping up; the protective wheel can be coaxially connected to the outside of the valve hand wheel. When the valve needs to be opened, the operator manually turns the protective wheel or turns the protective wheel with a common valve wrench, and the protective wheel drives The hand wheel of the valve rotates synchronously with it to open the valve. When the valve rod (screw rod) in the valve pops up under the pressure of the high-pressure medium, it will be blocked by the protective shell 4 at the center of the protective wheel to prevent it fr...

The invention discloses a protective device for high-pressure pipeline valves. The protective device comprises a protective wheel. The protective wheel can be coaxially connected to the outer ends of hand wheels of the valves and can drive the hand wheels of the valves to synchronously rotate; a protective shell for stopping lead screws of the valves from being popped out is fixed to the circle center of the protective wheel. The protective device has the advantages that the lead screws of the valves can be effectively prevented from being popped out in starting procedures, and accordingly the personal safety of operators can be protected.
