Embodiment Construction

[0008] Such as figure 1 As shown, the present invention is a duplex fuel filter, which is composed of a switching valve core 3 and two left and right chambers. The switching valve core 3 is located between the two chambers. The switching valve core 3 is divided into upper and lower chambers. Two flow passages, the two flow passages are T-shaped flow passages in the same direction, and an operating handle 12 is arranged on the top of the switching valve core 3, through which the switching valve core 3 is switched to communicate with the two chambers; Each chamber is provided with a filter body 1 and a filter cartridge 2, the filter cartridge 2 is set in the filter body 1, and the filter body 1 is respectively provided with openings corresponding to the upper and lower flow channels of the switching valve core 3; A gland 6 is provided on the upper end of the filter body 1, and a compression bar 8 is installed on the gland 6. One end of the compression bar 8 is pressed against th...

Abstract

The invention discloses a duplex fuel oil filter which consists of a change-over valve core (3), a left cavity and a right cavity, wherein an operating handle (12) is arranged on the top of the change-over valve core (3); a filter body (1) and a filter cartridge (2) are arranged in each cavity; each filter cartridge (2) is sleeved with the corresponding filter body (1); a gland (6) is arranged at the upper end of each filter body (1); a pressing crossbar (8) is arranged on each gland (6); a compressed spring (4) is arranged in each filter body (1); the top end of each compressed spring (4) is fixed with the corresponding gland (6); each filter cartridge (2) is pressed on the corresponding filter body (1) through the bottom of the corresponding compressed spring. According to the duplex fuel oil filter provided by the invention, when one group of filters cannot work due to blockage, the other group of filters can be switched to work, so that the machine is not influenced by blockage of the filters, and the filters can be cleaned or replaced under the non-stop condition.

Description

technical field [0001] The invention relates to a duplex fuel filter. Background technique [0002] Due to the continuous extension of the ship's route, the endurance of the ship must be greater and greater, and it is bound to require the ship to store enough fuel oil. After the increase in fuel oil demand, the shipowner controls the cost and the supplier in order to obtain greater economic benefits. The quality is greatly reduced, and the impurity content in it is inevitably increased, which forces to add a filter on the oil circuit; after the filter works for a long time, it is bound to easily cause blockage with the continuous increase of impurities. In this case, due to insufficient oil supply If it affects the normal operation of the machine, a filter that can be cleaned or replaced without stopping the machine is required. If a set of filters are connected in parallel in the pipeline system, this requirement can also be achieved, but it will increase the shipbuilding c...
