Abstract
The invention relates to an anti-scouring high-temperature gate valve which comprises a valve body, a valve cover, a valve rod, a valve base, a plug board and a transmission device, wherein an anti-rotation mechanism is arranged between the valve rod and the valve body; the valve body is formed in a way that a left valve body and a right valve body are welded through a middle valve body; the plug board is arranged in a plug board frame consisting of a left guide plate and a right guide plate; the upper end face of the plug board and the lower end face of the valve rod are in coordination connection by adopting a slope dovetail groove; the lower end face of the plug board and a slope wedge base are in coordination connection via a slope; the slope dovetail groove between the valve rod and the plug board moves at the initial stage when the valve is opened, so that the plug board is separated from a sealing surface of the valve base; the slope dovetail groove between the valve rod and the plug board moves at the later stage when the valve is closed, so that a wedge plug board and the valve base are sealed. The anti-scouring high-temperature gate valve has the advantages of simple structure, reliable sealing property and the like, and is suitable for the valve with high-temperature and hard powdery particle medium conditions.
Description
Technical field
The present invention relates to valve field, particularly about a kind of push-pull valve.The present invention is applicable to high temperature, powdery hard particles medium operating mode.
Background technique
The structure of push-pull valve has two kinds of open type push-pull valve and slat belt push-pull valves basically, and its basic structure all comprises left and right sides valve body, gate frame and flashboard start-stop device, and the gate frame can move between the valve body of the left and right sides through the flashboard start-stop device.Left and right sides valve body is generally through power screw sub-control distance between the two, when power screw are secondary when clamping left and right sides valve body, and the connection that in the valve body of the left and right sides, is sealed and matched of gate frame; When power screw strutted left and right sides valve body, the gate frame can move in the valve body of the left and right sides, realized valve opening.Its shortcoming is that a slip joint need be established as Displacement system in valve body inboard, the left and right sides, and needs the clamping of the power screw sub-control left and right sides valve body that many group bolt and nuts form or strut, and complex structure, sealing reliability are poor.
Summary of the invention
The objective of the invention is shortcoming, a kind of simple in structure, the reliable high temperature antiscour of sealability push-pull valve is provided to the existing technology existence.
Technological scheme of the present invention comprises valve body, valve gap, valve rod, valve seat, plate, transmission device, is provided with anti-rotation mechanism between valve rod and the valve body, and valve body is welded to form through center valve body by left valve barrel, right valve barrel.Mainly be that plate is installed in the plate frame, this plate frame is made up of left guide plate and right guide plate, and right guide plate seals the passway that is installed in the right valve barrel inwall by screw, and right guide plate is shaped on the through hole concentric with the right valve barrel port hole; On the valve channel direction in left guide plate neutral position, be shaped on through hole; Both sides are fixedly mounted on the right guide plate through hex head bolt; Plate is installed in the middle slide that forms between left guide plate and the right guide plate; The pile-up welding hard alloy sealing surface is sealed and matched with the sealing surface of valve seat each other on the right plane of plate, and valve seat is made up of the hard alloy layer of right guide plate openings built-up welding on every side, fixedly mounts an inclined-plane wedging seat at the through hole downside of right guide plate; Plate upper-end surface and valve rod lower end surface are shaped on the inclined-plane that cooperatively interacts respectively, connect through dovetail groove between both inclined-planes; The plate lower end surface has the inclined-plane that cooperatively interacts with inclined-plane wedging seat; Fixed installation one positioning plate on the guide plate of a left side, this positioning plate has the surface of contact that cooperatively interacts with the valve rod periphery.
In above technological scheme, the angle between the inclined-plane of plate upper-end surface and the inclined-plane of lower end surface and the valve channel center line is 30 °～45 °.
The best is that the angle between the inclined-plane of plate upper-end surface and the inclined-plane of lower end surface and the valve channel center line is 40 °.
The best is that the inclined-plane on the inclined-plane of plate upper-end surface and the inclined-plane of lower end surface, the inclined-plane wedging seat, the inclined-plane of valve rod lower end surface be the pile-up welding hard alloy layer respectively.
Advantage of the present invention is that plate is installed in the plate frame of being made up of left guide plate and right guide plate; Adopt the inclined-plane dovetail groove to cooperatively interact between plate upper-end surface and the valve rod lower end surface and be connected, being cooperatively interacted by the inclined-plane between plate lower end surface and the inclined-plane wedging seat is connected, at the valve opening initial stage; Inclined-plane dovetail groove between valve rod and the plate moves each other; Make plate break away from sealing surface of seat, and in the valve closing later stage, the inclined-plane dovetail groove between valve rod and the plate move each other; Wedging plate and valve base sealing, it is simple in structure, sealability is reliable.
