Specific implementation mode
The embodiment of the present invention is described further below in conjunction with the accompanying drawings：
As depicted in figs. 1 and 2, the special coal valve of high-air-tightness coal gasifier includes the valve body 4 of cylindrical structure, in valve body 4
Equipped with spool, spool is fixed on valve core shaft 6 by link mechanism 7 by two symmetrical cambered surface valve plates 3 and is formed, cambered surface valve plate
3 are in close contact with 4 inner wall of valve body, and link mechanism 7 is closed loop configuration made of being hinged by several linking arms, 7 both ends of link mechanism
The linking arm being connected with cambered surface valve plate 3 is equipped with tensioning spring 8, and 8 one end of tensioning spring connects valve core shaft 6, valve by connecting rod
The connection rotation of core shaft 6 drives, and multiple grease pump 1 is connected on 4 wall of valve body.
Rotation driving includes drive cylinder 2 and actuating arm 5, and the push rod of drive cylinder 2 and 5 one end of actuating arm are hinged, driving
5 other end of arm is fixedly connected with valve core shaft 6.
Drive cylinder 2 and multiple grease pump 1 share a set of hydraulic system 9.
As shown in figure 3, multiple grease pump 1 includes drier oil pumping element and fuel reserve tank 12, drier oil pumping element is by one or more
Dry oil pump structural base member forms, and dry oil pump structural base member includes fuel-displaced nozzle assembly 10 and driving plunger assembly 13, is gone out
Nozzle component 10 is located at the end of driving plunger assembly 13, and fuel-displaced nozzle assembly 10 connects fuel reserve tank 12 by hydraulic oil pipeline, drives
Dynamic plunger assembly 13 connects hydraulic system 9 by hydraulic oil pipeline, drives plunger and fuel-displaced nozzle assembly 10 in plunger assembly 13
In plunger linkage.
By adjusting set 11 in drier oil pump mount base, adjusting sleeve 11 can adjust fuel-displaced nozzle assembly 10 and exist fuel-displaced nozzle assembly 10
Fitting depth in drier oil pump mount base adjusts the effective travel of plunger in fuel-displaced nozzle assembly 10, plunger by adjusting fitting depth
Effective travel determine the effective discharge of plunger, to realize the variable of dry oil pump.
According to practical working situation, the oiling point of multiple grease pump 1 is distributed in what valve body 4 was in close contact with cambered surface valve plate 3
Multiple location points.
The linking arm that 7 both ends of link mechanism are connected with cambered surface valve plate 3 is U-shaped, and the U-shaped linking arm at both ends passes through hinged company
It is hinged to connect arm, the hinge joint for the arm that is articulated and connected is connect by connecting rod with valve core shaft 6.
Cambered surface valve plate 3 is in close contact under the action of tensioning spring 8 with 4 inner wall of valve body, realizes zero clearance, the course of work
In, when valve opening, drive cylinder 2 pushes actuating arm 5, actuating arm 5 that valve core shaft 6 is driven to rotate, while valve core shaft 6 acts on
In link mechanism 7, link mechanism 7 is so that cambered surface valve plate 3 generates a reaction force, such 3 He of cambered surface valve plate to tensioning spring 8
Pressure reduces between 4 inner wall of valve body, has the tendency that forming gap, meanwhile, 1 priority task of multiple grease pump, in opening direction
Best filling-up area fills a butter, contributes to valve core rotation；When valve is closed, drive cylinder 2 pulls actuating arm 5, actuating arm 5
