Abstract
The utility model discloses a gate valve for a dust collecting pipeline, which comprises a left valve plate, a right valve plate, an insertion plate and a cylinder, wherein the left valve plate and the right valve plate are the same in size. The insertion plate is arranged between the two valve plates, the valve plates and the insertion plate are in pressure welding through sealing rings, the insertion plate is capable of vertically sliding between the two valve plates, the insertion plate is provided with a round hole as same as the pipeline in inner diameter, one end of the cylinder is fixed, and the other end of the cylinder is connected with the top of the insertion plate. When in operation, the gate valve is closed, a piston of the cylinder drives the insertion plate to move downwardly, and connecting pipes of the two valves are obstructed to be non-communicated, while the gate valve is opened, the piston of the cylinder drives the insertion plate to move upwardly to a position leading the round hole on the insertion plate to be aligned to the connecting pipes on the valves, and the connecting pipes on the two valve plates are communicated with the round hole on the insertion plate. The gate valve for the dust collecting pipeline is simple in structure, convenient in operation, reliable in operation, tight when closed and not easy to accumulate dust, and can be widely applied to industrial production.
Description
Technical field
The utility model relates to a kind of valve on the dust sucting pipeline, specifically refers to a kind of dust sucting pipeline gate valve.
Background technique
All be through the negative pressure dust sucting pipeline ash-laden gas to be transported to deduster to remove flue dust at most flue gas dust collecting system at present; The dust pelletizing system that has requires the negative pressure dust sucting pipeline is carried out segmentation control; Just require pipe laying valve in pipe-line system this moment, to being opened and closed control by control valve road part.Because dust sucting pipeline is in negative pressure state, so valve needs sealing, and external leaks can not be arranged; And because the gas in the negative pressure dust sucting pipeline contains dust, easy dust stratification causes valve closing sternly and to sealing configuration not cause wearing and tearing in the pipeline valve, influences valve operational safety and working life.There is limited evidence currently of has and is fit to this control and contains the valve of the flue gas of dust, if general valve is installed, will cause being not closed completely and phenomenon that valve is easy to wear.
The model utility content
The purpose of the utility model be to provide a kind of valve closing tight, be difficult for dust stratification, valve opening, close dust sucting pipeline gate valve easily.
The utility model adopts following technological scheme, and a kind of dust sucting pipeline gate valve includes size identical left valve plate, right valve plate and plate and cylinder; Left side valve plate and the stack of right valve plate are fixing, and said plate is arranged between two valve plates; Be provided with the hole measure-alike at said left valve plate and right valve plate top with dust sucting pipeline; Be provided with same hole in corresponding position, said plate bottom; The hole of passing on said left valve plate and the right valve plate is set with adapter respectively; Hole on left and right valve plate is provided with groove, in said groove, is provided with seal ring; Said cylinder one end is fixed, and the other end is connected with the plate upper end.
Said left valve plate and right valve plate both sides are provided with flanging in the opposite direction, and said left valve plate and right valve plate adopt bolt to be connected the stack setting through the flanging on both sides.
Said plate top is provided with flanging in the opposite direction.
Said cylinder is two, and said two cylinder one ends are fixedly set in respectively on the side flanging of left valve plate and right valve plate, and the other end is fixedly connected the top margin flanging of plate respectively.
Big 0.1 ~ the 0.5mm of thickness of the gap ratio plate between the adapter opposing end surface on said left valve plate and the right valve plate.
In the utility model; Be weldingly fixed on the left and right valve plate two and take over ends and be connected with dust sucting pipeline through pipe jointer, the other end passes two eyelet weldings on the valve plate and connects fixingly, is provided with plate between two valve plates; Required distance between the adapter end face on the left and right valve plate is than the big 0.1 ~ 0.5mm of thickness of plate; Plate can slide up and down between two valve plates, and through being arranged on the seal ring sealing on a left side, the valve plate, the groove on internal diameter of the seal ring and end requirement and the left and right valve plate has 10% to 20% pre compressed magnitude between plate, valve plate and the adapter; The flanging of left and right valve plate dual-side is fitted; Connect left and right valve plate fixed connection through bolt, the cylinder body of two cylinders is fixedly set in two side edgefolds of left and right valve plate respectively, and cylinder piston rod is connected with the flanging at plate top.
When gate valve was closed, cylinder piston drove plate downwards and moves down, and staggered in the adapter position on hole of offering on the plate and the left and right valve plate, caused taking over by plate cutting off and not communicating; When gate valve was opened, cylinder piston upwards drove hole and the adapter position on the valve plate that plate is moved upward on the plate and aligns, and then the adapter on two valve plates communicates through the circular hole on the plate.There is pre compressed magnitude the internal diameter and the end of two seal rings, make this gate valve be in sealing state all the time.
From the above mentioned, that the related a kind of dust sucting pipeline gate valve of the utility model has is simple in structure, easy to operate, it is tight to close, be difficult for advantages such as dust stratification, reliable operation, can be widely used in the commercial production.
