Abstract
The utility model discloses a kind of pipeline valve bidirection press protective gear; this device connects in certain sequence primarily of pipeline trunk line, valve, bypass duct, rupture disk, No. two rupture disks; valve installation is on pipeline trunk line; bypass duct and valve in parallel are arranged on pipeline trunk line, and a rupture disk and No. two rupture disks are arranged on bypass duct successively.By arranging a two rupture disk bypass with valve in parallel, when valve is surprisingly closed by mistake, no matter there is water attack in the side, direction of starching of valve, or there is water attack in the slurry side, direction of going of valve, having rupture disk to protect valve; Penetrate into pipeline trunk line by bypass duct, there is rupture disk is released after water attack coal slurry and to release the opposite side of pipeline trunk line in certain side, effectively prevent coal slurry and release in pipe-line system external environmemt, avoid befouling environment.This apparatus structure simply, safely, reliably.
Description
Technical field
The utility model relates to a kind of pipeline valve bidirection press protective gear, can be widely used in long-distance transportation through pipeline system, belongs to coal slurry pipeline process technology equipment field.
Background technique
In long-distance transportation through pipeline coal slurry engineering, general freight volume is large, haul distance is long, caliber is large, pressure is high, and requires to ensure in pipe conveying procedure to run continuously as far as possible.Because pressure rating is high, caliber is large, and the valve being installed on pipeline trunk line is expensive, and if once occur that valve is surprisingly closed by mistake, gently then cause and run time-out completely, heavy then may cause booster leakage accident, consequence is hardly imaginable.Therefore, must take measures to tackle valve surprisingly to close by mistake.At present, in long-distance transportation through pipeline coal slurry engineering, generally take to starch at valve the mode that rupture disk is set up in side, direction, by rupture disk explosion coal slurry released and to pipe-line system external environmemt, reduce pipe-line system internal pressure protect valve.Although which can prevent valve because damaging valve or pipe explosion accident at the surge pressure starching side, direction after unexpected closedown by mistake, this mode reveals the problem that coal slurry causes environmental pollution after still not solving rupture disk explosion; And after valve is surprisingly closed, the slurry side, direction of going of valve often produces violent reverse water hammer by mistake, huge surge pressure may cause valve to damage or pipe explosion accident going slurry side, direction equally, and which can not be solved.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of pipeline valve bidirection press protective gear, and by arranging a two rupture disk bypass with valve in parallel, protect surge pressure two-way after valve closing, this apparatus structure simply, safely, reliably.
The technical scheme in the invention for solving the above technical problem is: a kind of pipeline valve bidirection press protective gear connects in certain sequence primarily of pipeline trunk line, valve, bypass duct, rupture disk, No. two rupture disks; described valve installation is on described pipeline trunk line; described bypass duct and described valve in parallel are arranged on described pipeline trunk line, and a described rupture disk and described No. two rupture disks are arranged on described bypass duct successively.
Further, the installation direction of a described rupture disk be the direction of releasing of a described rupture disk with to starch direction identical, the installation direction of described No. two rupture disks is that the direction of releasing of described No. two rupture disks is with to starch direction contrary.
Further, the caliber of described bypass duct is identical with the design pressure of described pipeline trunk line.
Further, the setting pressure of a described rupture disk and described No. two rupture disks equals the design pressure of described valve.
The beneficial effect of this pipeline valve bidirection press protective gear: by arranging a two rupture disk bypass with valve in parallel, when valve is surprisingly closed by mistake, no matter there is water attack in the side, direction of starching of valve, or there is water attack in the slurry side, direction of going of valve, have rupture disk to protect valve; Penetrate into pipeline trunk line by bypass duct, there is rupture disk is released after water attack coal slurry and to release the opposite side of pipeline trunk line in certain side, effectively prevent coal slurry and release in pipe-line system external environmemt, avoid befouling environment.This apparatus structure simply, safely, reliably.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the structural representation of a kind of pipeline valve bidirection press of the utility model protective gear.
Above-mentioned number in the figure is described as follows:
1, pipeline trunk line 2, valve 3, bypass duct 4, rupture disk
5, No. two rupture disks
Embodiment
In FIG; a kind of pipeline valve bidirection press protective gear that the utility model provides connects in certain sequence primarily of pipeline trunk line (1), valve (2), bypass duct (3), rupture disk (4), No. two rupture disks (5); described valve (2) is arranged on described pipeline trunk line (1); described bypass duct (3) and described valve (2) are installed in parallel on described pipeline trunk line (1), and a described rupture disk (4) and described No. two rupture disks (5) are arranged on described bypass duct (3) successively.The installation direction of a described rupture disk (4) be the direction of releasing of a described rupture disk (4) with to starch direction identical, the installation direction of described No. two rupture disks (5) is that the direction of releasing of described No. two rupture disks (5) is with to starch direction contrary.The caliber of described bypass duct (3) is identical with the design pressure of described pipeline trunk line (1).The setting pressure of a described rupture disk (4) and described No. two rupture disks (5) equals the design pressure of described valve (2).
