Embodiment
[0016] Example: Figure 1-3 As shown, a circle of high-temperature-resistant silicone rubber gasket 7 is added between the upper arc surface of the oil-proof cover 1 of the present invention and the flange outer ring of the lower part of the driving mechanism, and is tightened by the connecting bolts 5 of the cover during installation. , the above-mentioned contact surface forms a sealing structure, and when the actuator oil leaks, it will flow down along the outer wall of the oil-proof cover 1 .
[0017] The lower part of the oil-proof cover 1 of the present invention is provided with an annular liquid storage tank 6, which can collect the oil leakage of the actuator, so that the staff can find the valve device of the oil leakage in time and handle it.
[0018] The oil-proof cover 1 of the present invention is provided with an observation window 3 at the corresponding opening of the upper bracket of the valve, so that abnormalities in the transmission screw or other component...

An oil leakage preventing device for supporting a valve driving device mainly comprises an oil shield and a heat insulation layer, wherein the oil shield is an annular sleeve which is formed by splicing two or a plurality of HALF structures and fits a support at the lower part of the valve driving device by structure shape; splicing ports of the two or a plurality of HALF structures are abutted through flange plates and are fixedly connected through bolts; a high-temperature-resistant silicone rubber sealing gasket, which is in contact with an outer circle of a flange at the lower part of thevalve driving device and forms a seal, is arranged at the inner side of an arc surface at the upper end of the oil shield; the high-temperature-resistant silicone rubber sealing gasket is fastened through a connecting bolt of the oil shield during being mounted; the heat insulation layer is attached to the inner side surface of the oil shield; an annular outward convex liquid storing groove whichis mainly used for collecting oil leaking from the valve driving device is arranged at the lower part of the oil shield; and an observing window, which is used for daily inspection and is manufacturedthrough transparent Teflon material, is arranged at an opening, corresponding to the support on the valve driving device, of the oil shield.
Description
technical field [0001] The invention relates to an oil leakage prevention device matched with a valve driving device, which prevents the safety risk of oil leakage and burning in the driving device of a high temperature valve of industrial equipment, and belongs to the technical field of heat preservation. Background technique [0002] The gearbox of the valve driving mechanism is equipped with a large amount of lubricating oil to help the driving mechanism work smoothly. The valves in the high-temperature pipeline system in the industrial plant operate in a high-temperature environment all the year round, but after many years of operation, the driving mechanism of some valves has oil leakage. Phenomenon, the oil at the leak may cause the risk of burning. In the existing high-temperature pipeline system, no insulation measures are installed at the upper end bracket of the valve, resulting in the high temperature of the driving mechanism reaching about 200 ° C. The electrical ...
