Description

Technical Field:

[0001] The utility model relates to a switching tool, in particular to a tool for realizing online disturbance-free switching of a duplex oil filter, belonging to the technical field of duplex oil filters. Background Technique:

[0002] A duplex oil filter is a mechanical device used for filtering fuel and lubricating oil. Its main function is to filter out dirt insoluble in oil to keep the oil clean. The duplex oil filter adopts a double-barrel structure, namely a working barrel and a spare barrel. Under normal working conditions, when the pressure drop of the working filter element exceeds the specified value, it is necessary to rotate the switching valve to switch the working filter element to the spare filter element and check and clean the original filter element cavity to ensure the continuous normal operation of the oil filter. This design enables the replacement and cleaning of the filter element without shutting down the equipment, improving the operation efficiency of the equipment.

[0003] During the use of the duplex oil filter, due to the compact installation position of the equipment facilities, the switching handle of the oil filter is designed to be short, and the moving space is limited. It is difficult for the operator to operate, and the operator is easily bumped or scratched during the operation, affecting the online switching operation of the modified oil filter. At the same time, the unsmooth operation process may also cause an instantaneous decrease in oil pressure, which may further trigger the interlock shutdown of the unit. Therefore, a tool for realizing online disturbance-free switching of a duplex oil filter is proposed. Content of the Utility Model:

[0004] The purpose of the utility model is to provide a tool for realizing online disturbance-free switching of a duplex oil filter to solve one of the problems raised in the above background technique.

The oil filter assembly includes a tee and a handwheel; a switching valve is installed inside the tee, and the top of the switching valve is rotatably connected to the handwheel;

[0006] A switching assembly is arranged at the top of the oil filter assembly. The switching assembly includes a sleeve, a magnet, a card slot, a connecting rod, and an operating handle; a card slot is opened at the bottom of the sleeve, a magnet is fixedly connected to the inner side wall of the card slot, a connecting rod is fixedly connected to the top of the sleeve, an operating handle is fixedly connected to the top of the connecting rod, and the handwheel is arranged inside the card slot. After the oil passes through the tee, under the action of the switching valve inside the tee, it flows into the first housing or the second housing. After being filtered by the filter element inside the housing, the oil is sent out through the return oil pipe. When it is necessary to switch the oil flow direction, the handwheel of the original switching valve is connected through the sleeve and the magnet, and the operator rotates the operating handle. The torque is transmitted through the connecting rod and the operating handle to make the switching valve complete the switching action.
