Abstract
The utility model relates to a multiple channel rotary valve of the cyclic operating valve of a machine. The multiple channel rotary valve is particularly suitable for the matching parts of horizontal and vertical pipeline conveying systems used for cleaning the ash of a heat-engine plant. A rotary valve core is supported on the bearing of a pipe body, and the valve core is sealed by a seal ring and high pressure water. Output channels are distributed under the drive of an oil motor and a driving sprocket, thus the possibility of conveying large granular ash (d <= 60 mm) is solved, and the multiple channel rotary valve is a necessary matching part. The multiple channel rotary valve can be also matched with other conveying systems, and the multiple channel rotary valve is worthy of popularization.
Description
The present invention relates to a kind of multichannel rotary valve of machine cycles operating valve class, be specially adapted to employed horizontal, riser feedway in the power station mixed ash and slag handling system, and supporting use in other pipeline transporters.
The lime-ash removing is an important and difficult problem in the thermal power plant now, and the grey quantity of slag is big, the particle inequality.No matter carry and want instant, otherwise consequence is serious, be second use or remote the stacking, all wants fast processing to go out the scene.Ash-slag delivery mechanical varied as removing conveying with oil pump, be at present still at the machinery that uses, but using effect is bad, and oil consumption is big, and carries particle d≤1 millimeter.Riser feedway, water are carried, and have saved oil consumption, but particle remains d≤1 millimeter.This machinery support uses kit many, and unreliable factor is many, safeguards complexity, and shortcoming is still a lot.Use the horizontal pipeline feedway, it is the direction that each state of the world today all uses in research, it can not adopt, and three big mixing remove jar in the riser feedway, remove but in pipeline, mix, and conveying particle d≤60 millimeters, distance can reach 50～60 kilometers, but key issue is to use rotary valve to realize.
Purpose of the present invention is exactly the rotary valve that a kind of new design will be provided.This valve is two paths, three paths, four-way road or multi-path, valve body is one, two, three or more valve body, can adapt by system requirements and be matched in horizontal or vertical hydraulic conveyor system, reach other transmission device systems, and can replace the multichannel rotary valve of the multiple kit in the vertical Hydraulic Transportation System.
Employing by rotary valve body, distribute the rotary valve of the various paths that spool, leakage protection device, transmission device, bearing device etc. form, can reach purpose of the present invention.
Accompanying drawing 1: be a kind of three path rotary valve sectional drawings of the present invention.
Accompanying drawing 2: be a kind of three path rotary valve A-A cut-away views of the present invention.
No. three revolving valves be multiple channel rotary valve one of them, be representative typical structure, the valve arrangement of other various paths and No. three revolving valve structures are similar, just path what change. At base (9) valve body (4), bearing (2) (8), supporting spool (7) are housed, the spool two ends seal with seal cage (6), the mixed slag slurry of filler (3) sealing is housed in it can not outflow, valve body (4) exit, wear ring (5) is housed, can comes the adjusting play by B place trimmer with a period of time.
When the mortar that is transferred advances spool from C, can need to be exported by the road to the mortar field by I, O, K three-way respectively by action, spool (7) is under the oil motor transmission, turn round respectively and aim at wherein a bite of I, O, K by the time, according to duct arrangement, outlet of every aligning has mortar to send, and carries the mortar purpose and reach.
The present invention can reach the requirement of system, respectively the rotary valve of configurable two paths, three paths, four-way road, five-way road, multi-path according to on-the-spot and design needs on structure.Each part generally all carries out the surface hardening processing in valve, valve port place pile-up welding hard alloy, and yet available low grade is not handled material, particularly can play under the lubrication condition at medium, supporting portion also can reach the load size according to the rotating speed size, adopt sliding bearing, or double, arrange rolling bearing more.Output shaft connects also available shaft coupling, is connected to other mechanical variable speed systems, drives to can be hydraulic pressure, electronic or manual.
Reach arrangement as required, rotary valve also can be designed to two valve bodies, three valve bodies or more a plurality of valve body and combine.
The present invention contrasts prior art following advantage:
1, thoroughly improved existing lime-ash transporting system.
2, can once carry particle d≤60 millimeter, reduce mill slag link, remarkable in economical benefits.
3, system's link greatly reduces, and reliability increases.
4, plant maintenance is simple.
The present invention can solve the conveying of power station lime-ash, also can be used on the particle in the other industry, the line transportation of the shape thing that looses, and as supporting uses of oarse-grained conveying such as ore, coal cinder powder, refuses, is a kind of product of worth employing.
