Abstract
The utility model provides a soft sealed dusting valve with a self-locked connecting rod, which comprises a valve body and an upper-cover sealer fixed on top of the valve body. A valve plate is located at the bottom of the upper-cover sealer. A sealing ring cover is used to fix the sealing ring on the valve plate. The sealing ring and the lower hole of the upper-cover sealer constitute a sealing pair. The valve plate is connected with a hold-down arm. The other end of the hold-down arm is fixed on the valve rod. The valve body is supported on the valve pod. The utility model is characterized in that a four-bar self-locked linkage and a cylinder are provided at one end of the valve pod which stretches out of the valve body. The four-bar self-locked linkage comprises the cranks, the linkages and a self-locked positive stop. One end of the two cranks is hinged with the valve body and the valve pod while the other end is hinged with two ends of the linkage. The self-locked positive stop is fixed at the external wall of the valve body. The front end of the cylinder is hinged with the bar. The piston rod is hinged with the valve pod. The utility model makes the valve convenient for maintenance and replacement of sealing ring even in the pipe. The four-bar self-locked linkage is used to help the mechanism achieve the dead point when the valve plate is closed. Therefore, the sealing performance of the dust valve is not affected even some places inside the gas path or the cylinder are mal-functional.
Description
Technical field

Background technology
Blast furnace dry method dust is after blast furnace top pressure improves at present, and traditional Unloading ball valve is prone to leakage, causes the grit wearing and tearing of valve sealing ring and spheroid.As in use breaking down, then must from pipeline, pull down ball valve, not only make troubles, and hinder the ordinary production of blast furnace and dust collecting process to maintenance; And traditional pneumatic ash discharge clock valve, at compressed air pressure low or stop or situation that cylinder breaks down under, valve is subjected to can to open automatically under gas pressure and the action of gravity of dirt ash, causes gas leak.The patent No. is that the utility model of 03258959.X discloses a kind of auto-locking suspension spherical offset clock valve and adopted self-locking mechanism, and is provided with and repairs the mounting or dismounting hole; Its self-locking mechanism is made up of pusher dog assembly and lock hook assembly.
Summary of the invention
The purpose of this utility model is to provide a kind of connecting rod self-locking soft seal unloading valve, overcomes the weak point of present used Unloading ball valve, clock valve, and a kind of maintenance convenience, reliable sealing unloading valve are provided.
The technical scheme that solves the problems of the technologies described above is: this connecting rod self-locking soft seal unloading valve, its basic structure comprises: valve body, be fixed in the loam cake sealing member on valve body top, loam cake sealing member bottom is provided with valve plate, use sealing-ring gland fixed seal ring on the valve plate, interruption-forming sealing pair under sealing-ring and the loam cake sealing member, valve plate connects clamping arm, the clamping arm the other end is fixed on the valve rod, valve rod is supported on the valve body, it is characterized in that: valve rod stretches out the outer end of valve body four connecting rod self-locking mechanism and cylinders is set, four connecting rod self-locking mechanisms are by crank, connecting rod, the spacing composition of self-locking, two cranks, one end is hinged with valve body and valve rod respectively, and the other end is the articulated linkage two ends respectively, the spacing valve outer wall that is fixed in of self-locking, cylinder block front end and rod hinge connection, piston rod and valve rod are hinged.
The valve body of described connecting rod self-locking soft seal unloading valve is offered inspection manhole, and manhole plate is installed.
The valve plate bottom surface of described connecting rod self-locking soft seal unloading valve is provided with the otic placode of offering slotted hole, and slotted hole cooperates with steady brace on being fixed on clamping arm.
The spacing design of valve body self-locking of described connecting rod self-locking soft seal unloading valve comprises four connecting rod self-locking mechanisms and can adjust bolt.
The utility model is opened inspection manhole on valve body, thereby makes valve just can overhaul and change sealing-ring easily in pipeline; Adopt four connecting rod self-locking mechanisms, four connecting rod self-locking mechanisms arrive the dead point and form self-locking after valve plate is closed, even therefore break down in certains such as gas circuit, cylinders, also can not influence the sealing property of unloading valve, are particularly useful for the exhaust system of gas ash.

Embodiment
Fig. 1 is the sectional view of the utility model connecting rod self-locking soft seal unloading valve embodiment, the affixed loam cake sealing member 1 in valve body 10 tops, loam cake sealing member 1 bottom is provided with valve plate 5, use sealing-ring gland 3 fixed seal rings 4 on the valve plate, interruption-forming sealing pair under sealing-ring and the loam cake sealing member, valve plate 5 connects clamping arm 13, the clamping arm the other end is fixed on the valve rod 11, valve rod is supported on the valve body 10, valve rod stretches out the outer end of valve body four connecting rod self-locking mechanisms 7 and cylinder 8 is set, valve plate 5 bottom surfaces are provided with the otic placode of offering slotted hole, slotted hole cooperates with steady brace 14 on being fixed on clamping arm 13, valve body 10 is offered inspection manhole, and manhole plate 9 is installed.
Fig. 2, unloading valve door folding condition embodiment shown in Figure 3, four connecting rod self-locking mechanisms 7 of the present utility model are by crank 7-1,7-2, connecting rod 7-3, the spacing 7-4 of self-locking forms, and two crank 7-1,7-2 one end are hinged with valve body 10 and valve rod 11 respectively, the other end is articulated linkage 7-3 two ends respectively, the spacing 7-4 of self-locking is fixed in valve body 10 outer walls, cylinder 8 cylinder body front end and rod hinge connections, and piston rod and valve rod 11 are hinged,, the valve body self-locking is spacing to be comprised four connecting rod self-locking mechanisms and can adjust bolt 7-4.
The utility model adopts the soft seal valve plate, and the valve plate proximal most position that distance is opened on valve body is opened inspection manhole, thereby makes valve just can overhaul and change sealing-ring easily in pipeline; Adopt four connecting rod self-locking mechanisms, mechanism arrives the dead point and forms self-locking after valve plate is closed, even therefore break down in certains such as gas circuit, cylinders, also can not influence the sealing property of unloading valve.
