Description
Technical field:
The utility model relates to mechanical field, relates in particular to the valve for fluid control, particularly a kind of mazy type dropping valve.
Background technique:
In prior art, in industrial fluids pilot line, various valves are widely used.Due to the pressure of fluid circuit distinct device need not, therefore, conventionally need to adopt voltage drop method fluid pressure to be regulated at the pipeline place that need to regulate pressure.In industrial fluids, conventionally contain particulate matter impurity, the spool of dropping valve is caused to wearing and tearing, reduce working life; Meanwhile, the step-down grade of existing dropping valve is few, and the regulating effect of fluid pressure is poor.
Summary of the invention:
The purpose of this utility model is to provide a kind of mazy type dropping valve, and described this mazy type dropping valve will solve that dropping valve fluid pressure in prior art regulates that grade is few, granule foreign causes the technical problem that valve reduces working life in fluid.
This mazy type dropping valve of the present utility model, comprise valve body, valve seat, spool, valve rod and valve gap, in described valve body, be provided with choke manifold, described valve seat is arranged in valve body, described spool is arranged on valve seat, spool is connected with valve rod lower end, described valve gap is connected with valve body, and by seal spool, wherein, in described valve body, the axis that is positioned at the choke manifold of spool both sides becomes Z-shaped structure, spool is arranged with sleeve outward, between spool and sleeve, be provided with the pair that slides axially, stretch out from valve gap top valve rod upper end, between valve gap and the periphery of valve rod, be provided with filler, between the lower end of described filler and valve gap, be provided with lower liner, filler upper end is provided with filler pressing sleeve, the upper end of described filler pressing sleeve is provided with gland, described gland and valve gap are bolted.
Further, filler is along the axial stacked setting of valve rod.
Further, described filler is graphite packing.
Further, the lower end of described valve rod is connected with spool by bolt.
The utility model and prior art are compared, and its effect is actively with obvious.The utility model adopts mazy type choke manifold in dropping valve, can increase the flow resistance of fluid in throttle valve, increases restriction effect, can reach at most 32 grades of step-downs, differential pressure can reach 42MPa emptying, against corrosion, wear-resistant, low noise, more than overall internals hardness can reach HRC73.
Brief description of the drawings:
Fig. 1 is the structural representation of mazy type dropping valve of the present utility model.
Embodiment:
Embodiment 1:
