Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
As shown in fig. 1, 2 and 3, the utility model discloses a base 1 for connecting the servo valve is equipped with filter core mount pad hole on the base 1, is the filter core mount pad hole of the lower extreme threaded connection base 1 of circular cupped block 2 to be equipped with O type sealing washer 7 between the inner wall in block 2 and filter core mount pad hole, thereby make the inner chamber that block 2 and base 1 constitute keep sealed. The central authorities in base 1's filter core mount pad hole are equipped with the counter bore, and the lower extreme sealing connection counter bore of adapter sleeve 5, in this embodiment, the lower extreme symmetry of adapter sleeve 5 is provided with a plurality of axial short flute 51, and the lower extreme inner wall of the hole of adapter sleeve 5 is equipped with big end down's tapering, and the expansion ring 6 is the ring form, and the expansion ring 6 compresses tightly in the hole of adapter sleeve 5 and rises tightly the lower extreme of adapter sleeve 5 in the counter bore of base 1 to ensure adapter sleeve 5 and counter bore firm in connection and keep sealed. When the connecting sleeve 5 is assembled, the connecting sleeve 5 is only required to be inserted into the counter bore, the expansion ring 6 is placed into the inner bore of the connecting sleeve 5, the expansion ring 6 is knocked downwards, and the lower end of the connecting sleeve 5 is expanded outwards and is tensioned in the counter bore due to the taper of the inner wall of the lower end of the inner bore of the connecting sleeve 5, so that the assembling is convenient and fast, and the efficiency is high. The filter element 4 arranged in the cap 2 is connected with the connecting sleeve 5 in a sealing way (an O-shaped sealing ring is arranged in the connecting hole of the filter element 4), the inner cavity of the cap 2 is divided into an outer oil cavity 23 and a clean oil cavity 24 by the filter element 4, and an oil inlet hole 11 communicated with the outer oil cavity 23 and an oil outlet hole 12 communicated with the clean oil cavity 24 are arranged on the base 1. The welding of the top of block 2 has outer hexagon head 21, is equipped with the oil drain hole 22 of the inner chamber of intercommunication block 2 on the outer hexagon head 21, and plug screw 3 sealing connection oil drain hole 22.
