Abstract
The utility model relates to a low pressure cut-off control energy conservation valve. The low pressure cut-off control energy conservation valve comprises a valve body, wherein a large flow passage and a small flow passage are arranged in the valve body, a valve core is arranged on the large flow passage, a valve spring is connected with the valve core, and a positioning screw plug is connected with the valve spring. The low pressure cut-off control energy conservation valve can reduce flow passage pressure loss under high pressure status by increasing the size of an overflowing section, and has an energy conservation function.
Description
Technical field
The utility model relates to a kind of low pressure control energy-saving valve that dams.
Background technique
Throttle valve is by changing throttling cross section or chock length to control the valve of fluid flow.Conventional valve all only has a runner at present, and when highly pressurised liquid flows through, flowpath pressure loss is very large, extremely wastes energy.
Summary of the invention
The utility model is not enough for prior art, and a kind of low pressure control energy-saving valve that dams is provided, and it reduces flowpath pressure loss by increasing overflow section under high pressure conditions, has energy-conserving action.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of low pressure control energy-saving valve that dams, comprise valve body, in described valve body, be provided with large runner and small flow channels, on described large runner, be provided with spool, described spool is connected with valve spring, and described valve spring is connected with location plug screw.In use, small flow channels is in normally open, and when fluid pressure is little, spool is closed automatically, and liquid only passes through from small flow channels; When fluid pressure is large, spool is opened automatically, and liquid is respectively from large runner and small flow channels shunting process.
In technique scheme, described spool end is provided with round platform.Round platform is set and can be used to prevent that spool transition from moving down and blocking small flow channels.
In technique scheme, on described spool, be provided with groove, in described groove, be provided with Sealing.Prevent that highly pressurised liquid from leaking.
The utility model compared with prior art, has following beneficial effect: the utility model, under high pressure conditions, reduces flowpath pressure loss by increasing overflow section, has energy-conserving action.Round platform is set and can be used to prevent that spool transition from moving down and blocking small flow channels.Sealing can prevent that highly pressurised liquid from leaking.
Accompanying drawing explanation
Fig. 1 is the utility model schematic cross-section.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: referring to Fig. 1, a kind of low pressure control energy-saving valve that dams, comprise valve body 1, in described valve body 1, be provided with large runner 11 and small flow channels 12, on described large runner 11, be provided with spool 3, spool 3 can be arranged to the direction vertical with large runner 11.Described spool 3 is connected with valve spring 4, and described valve spring 4 is connected with location plug screw 5, makes valve spring 4 have certain compressive force, and valve spring 4 and hydraulic pressure are adapted to the effect in spool 3 cross sections.
Described spool 3 ends are provided with round platform 6, valve spring 4 can be arranged in a body, spool 3 ends enter in this body, round platform 6 is positioned at this body equally, this body plays one to round platform 6 to be stopped, thereby round platform 6 is set and can be used to prevent that spool 3 transition from moving down, transition moves down can break small flow channels, and block small flow channels.
On described spool 3, be provided with groove 7, in described groove 7, be provided with Sealing 8.Prevent that highly pressurised liquid from leaking.
In use, small flow channels 12 is in normally open, and when fluid pressure is little, spool 3 is closed automatically, and liquid is only from small flow channels 12 processes; When fluid pressure is large, spool 3 is opened automatically, and liquid is respectively from large runner 11 and small flow channels 12 shunting processes.Consider spool 3 stressing conditions: spool 3 is subject to active force T and the Water Pressure power F of valve spring 4.F=PXS, P is hydraulic pressure, S is spool 3 section area.When F < T is PXS < T, spool 3 is closed automatically; When F > T is PXS > T, spool 3 is opened automatically.
Claims (3)
1. the low pressure control energy-saving valve that dams, comprise valve body (1), it is characterized in that: in described valve body (1), be provided with large runner (11) and small flow channels (12), on described large runner (11), be provided with spool (3), described spool (3) is connected with valve spring (4), and described valve spring (4) is connected with location plug screw (5).
