[0030] In the embodiment, a first inclined surface 111 for contacting the ceramic ball 9 is arranged on the inner side edge of the lower part of the gland 11, and a second inclined surface 212 for contacting the ceramic ball 9 is arranged on the inner side edge of the upper part of the rotating seat 2. After the valve island 3 is inserted into the rotating seat 2 and the gland 11 is fixedly installed on the rotating seat 2, the valve island 3 is in contact with the first inclined surface 111 of the gland 11 and the second inclined surface 212 of the rotating seat 2 through the ceramic ball 9. Since the first inclined surface 111 of the gland 11 contacts the ceramic ball 9 during assembly, the valve island 3 is stably and rollingly contacted with the rotating seat 2 and the gland 10 through the ceramic ball 9. Since the first inclined surface 111 of the gland 11 always contacts the ceramic ball 9 during operation, the valve island 3 is limited when the first inclined surface 111 of the gland 11 contacts the ceramic ball 9, so that the valve island 3 is prevented from being separated upward from the rotating seat 2 during operation, and the overall operation stability of the equipment is improved.

[0031] In the embodiment, the gland 11 is locked and fixed on the rotating seat 2 by the first locking screw 13, and the rotating seat 2 is fixed on the top mounting port of the liquid cylinder 1 by the second locking screw 14.

[0033] Then the valve island 3, the ball mounting ring 7 and the support adjusting ring 8 are inserted into the central hole of the rotating seat 2 downwards until the first step face 311 of the valve island 3 is pressed and supported on the upper guide ring 4 of the support sealing piece, so that the support sealing piece supports the valve island 3 and seals the gap between the valve island 3 and the rotating seat 2; then the gland 11 is sleeved on the outside of the valve island 3 and is fixed and installed on the rotating seat 2 through the first locking bolt 13, at this time, the valve island 3 is in contact with the first inclined surface 111 of the gland 11 and the second inclined surface 212 of the rotating seat 2 through each ceramic ball 9; in this way, during rotation of the rotating seat 2 and the gland 11 with the liquid cylinder 1, the valve island 3 is in rolling friction contact with the rotating seat 2 and the gland 10 through each ceramic ball 9, so as to ensure stable and smooth movement of the equipment, and the valve island is very convenient to install;

[0034] During disassembly, first, the first locking bolt 13 is loosened and removed, then the gland 11 is removed, at this time, the valve island 3, the ball mounting ring 7, each ceramic ball 9 and the support adjusting ring 8 can be taken out of the rotating seat 2; the valve island is very convenient to disassemble;

[0035] When the ceramic ball 9 needs to be replaced, the support adjusting ring 8 is only rotated downwards until the support adjusting ring 8 moves downwards to a position where the ball mounting ring 7 does not limit the ceramic ball 9, at this time, the ceramic ball 9 can be taken out and replaced, after the ceramic ball 9 is replaced, the support adjusting ring 8 is re-rotated upwards to a position where the ball mounting ring 7 can limit the ceramic ball 9 again; the ceramic ball 9 is very convenient to install and replace.

[0036] The valve island of the utility model has the advantages that: (1) the valve island can be conveniently disassembled and maintained, the disassembly process saves time and effort, and the assembly and maintenance efficiency is improved; (2) no lubricating oil can be added, the liquid cylinder is not polluted by materials during operation, and the device is safe and sanitary, and cleaning is not needed; (3) the cost is relatively low, and the use cost of enterprises is reduced.

[0037] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application in any other form, and any modification or equivalent change made according to the technical essence of the present application still falls within the scope of the present application.
