Description
Technical field
The present invention relates to the two-bit triplet selector valve, a kind of two-bit triplet powder reversing valve that the switching of fluidisation dry coal powder between different pipe-line systems flowed that can be applied in the dry coal powder pressure gasifying process, realize of more specifically saying so.
Background technique
In the dry coal powder pressure gasifying process, coal dust must be all the time under the driving of carrier gas, in the mode of gas delivery at cycle cooling plating drum with enter by burner to switch between the throwing coal pipeline system of gasification oven combustion gasification and flow.Disclosed two-bit triplet powder reversing valve is unsatisfactory.Such as, two-bit triplet selector valve commonly used generally comprises valve body, valve seat, rotor and drive unit.Two outlets of an import are arranged on the valve body.The rotor of sphere or taper is set in the valve pocket, offers L shaped on the rotor or T shape passage.Rely on valve base sealing between rotor and the valve channel.Drive unit and rotor coaxial or eccentric the connection.When rotor is communicated with the valve body import with an outlet, then material flows into from the valve body import, and should outlet flow out from valve body; Do 90 ° or the more revolution of wide-angle when drive unit drives rotor, rotor is communicated with the valve body import with another outlet, and then material flows into from the valve body import, and flows out from another outlet of this valve body.Do 90 ° of (or more wide-angle) revolutions by rotor, the material that enters valve body can be flowed out from two different outlets.In this structural type, when rotor was made large-angle slewing, the mobile direction wide-angle of solid material changed, flow resistance is sharply strengthened, very easily cause material to stop up, and the wearing and tearing between rotor and the valve seat and frictional resistance are big, material snaps between rotor and the valve body easily, causes the bite of rotor.
Practice shows: the rotor bite of selector valve and the excessive powder that causes of commutation flowing angle variation harden in pipeline, build bridge and will influence the stable operation of powder feeding device, make to produce to be difficult to keep.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology deficiency, provide a kind of and be particularly suited for being applied in the dry coal powder pressure gasifying process, realize the two-bit triplet powder reversing valve that the switching of fluidisation dry coal powder between different pipe-line systems flowed, to avoid the bite in the commutation process, guarantee the stability that powder is reinforced, reduce component wear, increase the service life.
Technical solution problem of the present invention adopts following technological scheme:

Through hole is set on valve body, and in valve body and gap between rotor, feeds the little clean inert gas that is higher than pressure medium of pressure by through hole.
Be respectively arranged with the bonnet and the bottom flange in tape spool hole at the two ends up and down of valve body, the two ends rotating shaft of rotor is radially positioned in the axis hole of bonnet and bottom flange by the bearing that is sleeved in the rotating shaft respectively; Be provided for the thrust plate of rotor axial location in the end face between rotor and bonnet.
On bottom flange, fixedly install the adjustable elastic gland that is used for the rotating shaft of rotor is formed axial pushing tow.
Seal ring is set between rotor and valve body in pairs; Two ends of rotor rotating shaft and bonnet and and bottom flange between, dust-proof seal ring is set respectively.
Seal ring is the lip seal ring of the springs preload of inflation.
Rotor drive is set, and the output shaft of rotor drive is connected with the rotating shaft of rotor, and rotor drive drives rotor and back and forth rotates with acute angle a.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, rotor of the present invention only realizes promptly that with the reciprocal rotation of acute angle a the switching of fluidisation dry coal powder between different pipe-line systems is mobile, valve commutation angle is little, turn around time is fast, make the flow direction of coal dust that violent change not take place, greatly reduce the reversed flow dynamic resistance, reduced the wearing and tearing of rotor, thereby effectively avoided situations such as hardening appears in powder material, bridge formation in pipeline, improve the operational stability of powder feeding device, increase the service life.
2, the present invention is because the twin-channel setting of parallel reducing in the rotor, coal dust flows out from different rotor channels respectively during commutation, all the time there is a passage to keep being communicated with in the commutation process, coal dust flows and is not stopped during commutation, keep fluidized state always, greatly improved the system works reliability and stability.
3, the present invention since the last lower rotary shaft of two ends of rotor by the bearing radial location that is arranged on the bottom flange, rotor axial is by the thrust plate location that is provided with between rotor end-face and the bonnet end face, when therefore rotor commutates under big pressure reduction, rotor and valve body keep matching gap evenly, axially not have play, have prevented the eccentric wear and the bite of rotor effectively.
4, the present invention is owing to feed the little clean inert gas that is higher than pressure medium of pressure in the gap of valve body and rotor, and seal ring is set in pairs between rotor and valve body, between two ends of rotor rotating shaft and bonnet and bottom flange, dust-proof seal ring is set respectively, make coal dust be difficult to enter gap between rotor and other part of valve, greatly reduce the possibility of coal dust bite rotor.
