Description
Technical field
The present invention relates to a kind of valve, particularly relate to a kind of multi-step pressure reduction valve.
Background technique
Reduction valve is by regulating, inlet pressure being reduced to the outlet pressure of a certain needs, to provide certain pressure lower than inlet side hydrodynamic pressure.At present, in fluid delivery system, decompression method adopts one-level throttling usually, utilize the relative position between taper valve and circular orifice to change orifice size, flow velocity and fluid dynamic energy are changed, causes the different pressure losses, thus reach the object of decompression.The reduction valve of one-level throttling is adopted not to be suitable for high-pressure situations, and the valve core structure that the taper valve of this kind of reduction valve and circular orifice match, lateral force is uneven, and throttling stability is bad, easily produces cavitation under high pressure, makes trim premature breakdown.
Summary of the invention
In order to overcome the above-mentioned shortcoming of existing reduction valve, the invention provides a kind of good stability, not easily producing flash distillation and cavitation, and can according to the multi-step pressure reduction valve of the pressure reduction design n level decompression sleeve of process system.
The technical solution adopted for the present invention to solve the technical problems is a kind of multi-step pressure reduction valve, comprise left valve barrel, right valve barrel, valve rod, guide shell, guide shell is fixedly connected with left valve barrel by axle bed, valve rod radial direction runs through guide shell and is fixed in axle bed, valve rod is positioned at guide shell inner chamber section and connects a shift fork, guide shell port is fixedly connected with a multi-stage sleeve, in multi-stage sleeve and guide shell inner chamber, a piston cylinder is set, piston cylinder and multi-stage sleeve and guide shell are positioned at same axis, piston cylinder axial location is fixedly connected with a piston rod, piston rod leading portion is fixedly connected with a bearing pin, bearing pin and shift fork are connected.
Multi-stage sleeve has several taper hole of falling loudspeaker.
Beneficial effect of the present invention is as follows:
1, can realize multistage throttle, thus well can reduce pressure under high-pressure situations, avoid the generation of cavitation, noise is low.
2, piston cylinder and guide shell and multi-stage sleeve are positioned at same axis, and are led by piston cylinder periphery, make guiding steadily, long service life, rational in infrastructure.
3, multi-stage sleeve has multiple taper hole of falling loudspeaker, after making gas medium step-down volumetric expansion, flow velocity at the uniform velocity promotes.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the plan view of the present embodiment;
Fig. 2 is the plan view of the present embodiment.
In Fig. 1,2: 1. guide shell; 2. left valve barrel; 3. axle bed; 4. valve rod; 5. piston rod; 6. multi-stage sleeve; 7. piston cylinder; 8. right valve barrel; 9. shift fork; 10. bearing pin; 11. taper holes.
Embodiment
As Fig. 1, shown in 2, a kind of multi-step pressure reduction valve, comprise left valve barrel 2, right valve barrel 8, valve rod 4, guide shell 1, guide shell 1 is fixedly connected with left valve barrel 2 by axle bed 3, valve rod 4 radial direction runs through guide shell 1 and is fixed in axle bed 3, valve rod 4 is positioned at guide shell 1 inner chamber section and connects a shift fork 9, guide shell 1 port is fixedly connected with a multi-stage sleeve 6, multi-stage sleeve 6 has multiple taper hole 11, in multi-stage sleeve 6 and guide shell 1 inner chamber, a piston cylinder 7 is set, piston cylinder 7 is positioned at same axis with multi-stage sleeve 6 and guide shell 1, piston cylinder 7 axial location is fixedly connected with a piston rod 5, piston rod 5 leading portion is fixedly connected with a bearing pin 10, bearing pin 10 and shift fork 9 are connected.
During work, actuate valve stem 4 rotates, and coordinating namely by shift fork 9 and bearing pin 10, makes piston rod 5 drive piston cylinder 7 to move linearly along the axis of guide shell 1 and multi-stage sleeve 6, so can realize the object reduced pressure.According to the pressure reduction of process system, the multi-stage sleeve 6 of different progression can be designed, realize different decompression objects.
