Description
Technical field
The utility model relates to the fluid control technology field of High Pressure Difference, particularly a kind of maze-type structure for modulating valve.
Background technique
Maze-type structure is mainly used in high pressure occasion, and medium, after the modulating valve of flowing through, by the decompression of labyrinth core bag, is eliminated cavitation phenomenon, reduces the noise of pipeline when valve working, extends valve working life.
The current maze-type structure for modulating valve, mostly be to adopt the stacked structure of labyrinth disc, there is the disc of complexity, special construction, utilize and on multiple discs, there are multistage 90 degree bending runners, improve the resistance coefficient of throttling element, reduce flow velocity, play certain throttling action, but this technical disadvantages is: because multistage radial flow path is 90 degree bendings, easily blocked by dirty at right-angle turning place, thereby affect the negotiability of valve, complicated runner operation simultaneously, the difficulty that has increased greatly processing, manufacturing efficiency is low, and cost is high.
Model utility content
In order to solve the deficiency of above technology, the utility model provides a kind of maze-type structure for modulating valve.
The utility model provides: a kind of maze-type structure for modulating valve, it comprises valve body, valve seat, valve gap, labyrinth core bag and mangetic core assembly, described valve seat is positioned at valve body, described valve seat is provided with labyrinth core bag, described valve gap is fixed on labyrinth core bag on valve seat by gland, and described mangetic core assembly is positioned at core bag inside, labyrinth, and described labyrinth core bag is made up of the stack of multi-disc labyrinth sheet, sheet symmetrical two ends in described labyrinth have runner, and described runner is staggered and forms by arrange cylinder boss more.
The cylinder boss diameter of described runner inner side is less than the diameter of outside cylinder boss.
N row's a cylinder boss is all positioned at the neutral position of two cylinder boss of n+1 row.
Between described gland and labyrinth core bag, be provided with balanced seal ring.
The beneficial effects of the utility model are: the runner that utilizes the cylinder boss on the sheet of labyrinth to form, realize step-down, and eliminate local cavitation phenomenon, runner does not have right-angle bending simultaneously, and particle is not easy deposition.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of labyrinth core bag.
Fig. 3 is the stereogram of labyrinth sheet.
Fig. 4 is the planimetric map of labyrinth sheet.
In figure, 1. valve body, 2. valve seat pad, 3. valve seat, 4. labyrinth core bag, 5. balanced seal ring, 6. gland, 7. bonnet gasket, 8. mangetic core assembly, 9. valve gap, 10. double-screw bolt, 11. nuts, 12. fillers.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, a kind of maze-type structure for modulating valve, it comprises valve body 1, valve seat 3, valve gap 9, labyrinth core bag 4 and mangetic core assembly 8, described valve seat 3 is positioned at valve body 1, described valve seat 3 is provided with labyrinth core bag 4, described valve gap 9 is fixed on labyrinth core bag 4 on valve seat 3 by gland 6, described mangetic core assembly 8 is positioned at core bag 4 inside, labyrinth, the valve rod that described mangetic core assembly 8 comprises spool and is connected with spool, between described valve rod and valve gap, be provided with filler 12, carry out encapsulation process by filler 12, valve gap is fixedly connected with nut 11 by double-screw bolt 10 with valve body.
Described labyrinth core bag 4 is made up of multi-disc labyrinth sheet stack, and sheet symmetrical two ends in described labyrinth have runner, and described runner is staggered and forms by arrange cylinder boss more.
The cylinder boss diameter of described runner inner side is less than the diameter of outside cylinder boss.
N row's a cylinder boss is all positioned at the neutral position of two cylinder boss of n+1 row.
There is the labyrinth sheet of some cylinder boss by multi-disc surface Machining, the labyrinth core bag that stack forms a whole, high-pressure liquid is when by labyrinth core bag, the runner being formed by multiple cylinder boss, increase the mobile damping of fluid, reduce the flow velocity of media flow, thereby reduced the pressure of medium.And on the sheet of labyrinth cylinder boss quantity and size can according to the step-down progression of actual conditions and need flow design.
The runner that utilizes the cylinder boss on the sheet of labyrinth to form, realizes step-down, eliminates local cavitation phenomenon, and runner does not have right-angle bending simultaneously, and particle is not easy deposition.
Between described gland 6 and labyrinth core bag 4, be provided with balanced seal ring 5, the design of balanced seal ring has improved the sealing between gland and labyrinth core bag, and meanwhile, balanced seal ring and mangetic core assembly formation are sealed and matched.
Between described valve gap 9 and gland 6, be provided with bonnet gasket 7, and between valve seat 3 and valve body 1, be provided with valve seat pad 2, ensure overall sealing.
Embodiment should not be considered as restriction of the present utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection domain of the present utility model.
