Plate, the valve plate shape match with material channel, rotate handwheel, and valve plate moves along roller-way and closes material channel, valve plate edge
When roller-way is mobile, end face and pass limit plate or are reached a limit plate and are fitted closely in place thereon.
By using above-mentioned technical proposal, when rotating handwheel, valve plate is slided along roller-way, is avoided valve plate from getting stuck deformation, is rubbed
The small switch motion of power is more convenient, and while moving is closed limit plate in place respectively and reaches a limit plate and abutted, by valve plate and roller
Road pushes against, its tilting is avoided to lead to be bonded not sternly influence leakproofness with cylinder inboard wall；Valve plate is mounted in side box body, valve plate closes
When closing, sealing space is both formed between side box body and cylinder, eliminate causes leakproofness insufficient due to opening up opening on cylinder
The problem of；It scrapes, keeps away even if valve plate upper surface bonding by material, limit plate in place can be closed in sliding and reaches a limit plate
Exempt to lead to clamping stagnation, obstruction, closes valve plate tight.
As preferred embodiment, the cylinder both ends are equipped with equipped with ring flange, convenient for docking gate valve with other equipment.
As preferred embodiment, the cylinder is cylinder, and the material channel is cylindrical channel.
As preferred embodiment, the side box body is formed by a top plate, both side plate, a bottom plate, connecting plate sealing fixation, bottom
Plate is from closing on to far from ramping up at the cylinder at the cylinder, and the screw rod is spirally connected with the connecting plate, and bottom plate is to incline
Ramp up state, when conveying can make the material fallen into side box body fall automatically.
It further include casing as preferred embodiment, described sleeve pipe covers on the screw rod for stretching out the side box body, avoids silk
Bar gets rusty or is infected with impurity.
As preferred embodiment, limit plate is Circular Plate in place for the pass, and limit plate is on the one hand by valve plate clamping in place for pass, separately
On the one hand it forms one layer of sealing structure again between valve plate top surface and cylinder inboard wall, further increases sealing effect when closing.
As preferred embodiment, roller-way is additionally provided on the cylinder inboard wall, roller-way is located at pass limit plate lower section in place, roller
Road closes limit plate in place valve plate clamping is prevented its loosening.
The beneficial effects of the utility model are: valve plate is slided along roller-way, and the small switch motion of frictional force is more when rotation handwheel
Conveniently, and when moving limit plate in place is closed respectively and reaches a limit plate and is abutted, and valve plate and roller-way are pushed against, its tilting is avoided
Causing to be bonded with cylinder inboard wall does not influence leakproofness sternly；Valve plate is mounted in side box body, when valve plate is closed, side box body and cylinder
Between both form sealing space, eliminating leads to the problem of leakproofness deficiency due to opening up opening on cylinder；Even if on valve plate
Surface bonding can be closed limit plate in place in sliding and reach a limit plate and scraped by material, and clamping stagnation, obstruction are avoided result in,
Close valve plate tight；It is driven using handwheel, screw rod, easy switching, rapidly, and meets ash bucket and used in the abnormal maintenance of conveying.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
