Abstract
The utility model discloses an automatic coke shoveling structure of an adjusting valve, comprising a guide sleeve arranged in the valve body, and a valve core handle that can move along the guide sleeve, wherein a plurality of annular slots are arranged on the valve core handle; a notch of each annular slot is a shovel; cokes on the wall can be shoveled when the shovel slides on the internal wall of the guide sleeve; the guide sleeve is internally provided with an axial deslagging slot; internal holes of the upper end and the lower end of the guide sleeve are sharp edges; and when the valve core handle moves up and down, the sharp edges can shoveled the cokes on the valve core handle. The automatic coke shoveling structure for the adjusting valve has a good coke shoveling effect, avoids the inconvenience of shoveling the cokes for cleaning periodically, and avoiding the jamming accident owning to coking.
Description
Technical field
The utility model relates to a kind of industrial process control valve, relates to a kind of modulating valve specifically and shovels the close-burning structure automatically.
Background technique
After striding into the new century, the industry of China enters structural adjustment period, and the chemical industry energy policy has been done great adjustment, is main turning to based on coal from oil.First procedure of Coal Chemical Industry is that coal is changed into synthetic gas, the low befouling environment again of the gas producing furnace efficient of former usefulness, and country makes a decision superseded; Adopt advanced in the world coal water slurry gasification furnace apparatus (hereinafter to be referred as gasification oven), gasification oven is listed country " 863 " plan in for this reason, tackles key problems successfully in 2005; Built first homemade gasification oven in Shandong Yankuangguotai Chemical Co., Ltd, day 1150 tons of coals of processing; Built up and produced 240000 tons of methyl alcohol demonstration projects per year.
Enter the water coal slurry (being commonly called as Heisui River) of gasification oven burning, existing very strong chemical corrosivity; After throttling, extremely strong erosion attack is arranged again; Also form coking in the gap of spool handle and guide pin bushing, valve rod is stuck.The main product of domestic modulating valve was the product of introducing from states such as the U.S. and Britain's moral days after the eighties at that time, was used to control general liquid state or gaseous medium, did not have specific functions such as erosion resistance, anti-plugging, shovel coking, therefore can't use.The gasification oven dedicated regulation valve was domestic gap product at that time, entirely by import, and the price sky-high price of saying so, working life is not long yet.
To shovel burnt function is example, and one of major defect that existing imported product exists is coking, and the guide pin bushing 3 ' of the dihedral modulating valve of import directly embeds bonnet 4 ', has designed a seal ring 2 ' at the end opening of guide pin bushing 3 ', and purpose is to block coal dust, sees Fig. 1.But guide pin bushing 3 ' is exposed in the torrent, and the permeability of water coal slurry is very strong again, can pass seal ring 2 ' through Gland 6 ' (5 ' is filler), forms coking in the same old way, and frequent stuck valve rod 1 ' is spent one or two months and taken apart once, manually roots out coking, the special cleaning.
The model utility content
The technical problems to be solved in the utility model provides a kind of modulating valve and shovels the close-burning structure automatically, and shovel is burnt effective, to overcome the defective that exists in the prior art.
The utility model is by the following technical solutions:
A kind of modulating valve shovels the close-burning structure automatically, comprises the guide pin bushing of being located in the valve body, with the spool handle that moves along guide pin bushing, described spool handle is provided with several annular grooves, the notch of annular groove is a perching knife, roots out coking on the wall when sliding between perching knife and the guide pin bushing inwall, is provided with axial dump tank in the guide pin bushing.
Preferably, described dump tank has several, and arranges along branches such as guide pin bushing circumference.
Preferably, described dump tank is shaped as semicircle.
Preferably, described perching knife is provided with the cutting edge of a knife or a sword mouth.
Preferably, two of described guide pin bushing ports are provided with the cutting edge of a knife or a sword mouth.
Preferably, the annular groove notch is welded with cemented carbide on the described spool handle.
The modulating valve that the utility model relates to shovels the close-burning structure automatically, and to shovel burnt effect fine, exempted the burnt worry of cleaning of regular shovel, do not take place because of the stuck accident of coking.
Description of drawings
Fig. 1 is the structural representation of modulating valve and guide pin bushing in the prior art.
Modulating valve and the automatic plan view that shovels the close-burning structure that Fig. 2 relates to for the utility model.
The modulating valve that Fig. 3 relates to for the utility model shovels the plan view of the spool handle in the close-burning structure automatically.
The modulating valve that Fig. 4 relates to for the utility model shovels the plan view of the guide pin bushing in the close-burning structure automatically.
Embodiment
Modulating valve and automatic shovel close-burning structure that Fig. 2 relates to for the utility model.In valve body 5, guide pin bushing 4 is located at, following two valve pockets 7, on the interlayer 9 between 8, be connected by spool handle 2 between valve core head 1 and the valve rod 6, spool handle 2 moves along guide pin bushing 4, spool handle 2 is provided with several annular grooves 3, the notch of annular groove 3 is perching knife 11 (see figure 3)s, the notch pile-up welding hard alloy, processing annular groove 3 backs stay the cutting edge of a knife or a sword mouth on perching knife 11, root out coking on the wall when sliding between perching knife 11 and guide pin bushing 4 inwalls, be provided with axial dump tank 10 in the guide pin bushing 4, this dump tank 10 is semicircular through slot, and several are arranged, and arranges along branches such as guide pin bushing 4 circumference, see Fig. 4, two port processing of guide pin bushing 4 also leave the cutting edge of a knife or a sword mouth.When valve rod 6 moved up and down, the coking of guide pin bushing 4 inwalls down of annular groove 3 shovels was discharged by dump tank 10 on the spool handle 2; The coking of the cylindrical of guide pin bushing mouth shovel lower valve core handle 2, shovel is burnt mutually for the two, and removes automatically.Spool handle 2 must be thick, and the piston actuator of assembly high thrust can have enough thrust shovels burnt like this.
The endoporus of guide pin bushing 4 by the five equilibrium angle, mill the dump tank 10 that processes semicircle up/down perforation, upper and lower port stays the cutting edge of a knife or a sword mouth, guide pin bushing 4 is pressed in the center hole of valve body 5 intermediate interlayers 9.The cylindrical of spool handle 2 has several annular grooves 3, and notch stays the cutting edge of a knife or a sword mouth; Heating spool handle 2 is pressed into the tailing axle of valve core head 1 in the taper hole of spool handle 2 during assembling, finishes hot jacket and connects; The following head thread of valve rod 6 is screwed in the spool handle 2, and valve core head 1, spool handle 2, valve rod 6 are formed a mangetic core assembly like this.Valve rod 6 upwards inserts the mounting hole of guide pin bushing 4 from the end opening of valve body 5.
After implementing the utility model scheme, the burnt effect of the automatic shovel of modulating valve is fine, has exempted the burnt worry of cleaning of regular shovel, does not take place because of the stuck accident of coking.
