Abstract
Description
Technical Field
[0001] The utility model relates to the field of protective covers, in particular to a rotary lead screw protective cover. Background Technique
[0002] Rotary lead screws in outdoor open environments are often soaked by rain, dew, and falling snow, and will rust when not maintained for a long time. Maintenance requires applying protective lubricating grease on the lead screw. However, since the grease is prone to adsorbing dust, an oil sludge is formed on the surface of the rotary lead screw. Therefore, during equipment maintenance, the lead screw must be wiped and cleaned regularly and the grease must be reapplied.
[0003] However, in order to reduce the number of equipment maintenance times and the labor intensity of equipment maintenance personnel during use, lead screw protective covers are widely used in outdoor open valves, sleeved outside the valve lead screw to protect the lead screw from rain and snow erosion. Currently, the widely used lead screw protective covers mainly include stainless steel protective covers, nylon sheaths, and plastic sheaths. However, the existing lead screw protective covers are all closed structures, and the thermal expansion and contraction of gas easily cause water vapor condensation in the closed space, which instead accelerates the rusting and corrosion of the valve lead screw. At the same time, the stainless steel protective cover cannot change its own length, and different protective covers are required for different lead screws. The nylon sheath and the plastic sheath are fixed to the lead screw through ropes. When used for a long time, the ropes are prone to weathering and breaking.
[0004] Therefore, the utility model provides a rotary lead screw protective cover to solve the problems raised in the above background technique. Content of the Utility Model
