Abstract
The utility model provides a device of a pipeline inserting valve. The device is characterized by comprising a flange plate and a flange blind plate which are fixedly connected to a pipe plate, wherein the pipe plate and a rod inserting rack for accommodating an inserting rod are fixed on a coal breakage pipeline; and sealing gaskets are respectively arranged between the flange plate and the flange blind plate as well as between the flange plate and the pipe plate. The device is arranged on the coal breakage pipeline on an inlet of a coal feeder and has the advantages of simple structure, bidirectionality and sealing function and is convenient to use; and meanwhile, the device has a certain dredging function on raw coal blocked in the pipeline at the inlet of the coal feeder.
Description
Technical field
The utility model relate to a kind of coal-feeding conveyer on the pipeline intubate control valve unit that falls, be used for run coal bin and export to pipeline between the coal-feeding conveyer import, belong to the raw coal technical field of conveying machinery.
Background technique
Coal-feeding conveyer is extensively applied in the coal-grinding pulverizing system of thermal power generation unit.To be that the body that enters coal-feeding conveyer through the last fuel dropping pipe and the coal gate of coal-feeding conveyer by run coal bin is defeated expect on the belt raw coal that coal-feeding conveyer is carried.In order to guarantee the normal operation of unit, require between run coal bin outlet and the coal-feeding conveyer import pipeline unimpeded, on the pipeline amount of flow that the coal valving is controlled coal must be set.Existing intubate door sealing is bad, and the direction of insertion is an one-way.If run into pipeline location when higher, there is very big inconvenience in the placement of intubate part.The switch of each intubate door takes time and effort, and is extremely inconvenient.
Summary of the invention
The purpose of this utility model provides a kind of direction of insertion and has the amphicheirality, has seal action, and the intubate part is placed convenient, can conveniently control the switch gear of ature of coal amount of flow.
In order to achieve the above object, the technical solution of the utility model has provided a kind of device of pipeline intubate valve, it is characterized in that: comprise flanged plate and blank flange, interchangeable must the connection of flanged plate and blank flange is fixed on the tube sheet, the inserted link frame that tube sheet and being used to is placed inserted link is fixed on the coal breakage pipeline, is respectively equipped with sealing gasket between flanged plate and blank flange and tube sheet.
Further, described flanged plate and blank flange are fixed on the described tube sheet by bolt, spring washer and nut connection.
The utility model is installed in the coal-feeding conveyer import on the coal breakage pipeline, and advantage is simple in structure, and is easy to use, has amphicheirality and seal action, also makes simultaneously to stop up raw coal in the coal-feeding conveyer inlet pipeline certain mediation effect is arranged.

Fig. 3 inserts schematic representation in the pipeline for inserted link;
Fig. 4 places schematic representation for inserted link.
Embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figures 1 and 2, the device of a kind of pipeline intubate valve that provides for the utility model, comprise flanged plate 2 and blank flange 5, flanged plate 2 and blank flange 5 are fixed on the tube sheet 10 by bolt 6, spring washer 7 and nut 8 connections, flanged plate 2 and blank flange 5 can exchange installation, thereby guarantee the amphicheirality of direction of insertion.Tube sheet 10 and inserted link frame 9 all are welded on coal breakage pipeline 4, and inserted link 1 is placed on the inserted link frame 9 usually.Sealing gasket 3 is placed between tube sheet 10 and flanged plate 2, the blank flange 5, has guaranteed the sealing of pipeline intubate valve.
As shown in Figures 3 and 4, for inserted link inserts in the pipeline and the schematic representation of placing, inserted link 1 passes through tube sheet 10 insertions of flanged plate 2 and homonymy and extracts the coal breakage pipeline out, plays the effect of switch coal stream.Usual inserted link 1 is placed on the inserted link frame 9, and inserted link 1 also can play the effect of mediation coal cinder simultaneously.
