Abstract
The utility model relates to a furnace gas regulation turncock for coke oven, which comprises a shell body, a core, a spring, a spring gland, a holding down bolt, a clearing plate, a gasket, an oil groove, a gas inlet, a gas outlet and especially a radial groove outside the oil groove and a hose coupler set in the shell body and is corresponding to the groove. This utility model is able to prevent the fire and explosion caused by gas leakage, thus protecting the personnel and equipments from hurt and damage.
Description
Technical field
The utility model relates to a kind of valve, particularly the regulating cock in the coke oven heating gas pipe line.
Background technique
At present, the coal gas of coke oven heating use mostly is blast furnace gas or producer gas.The regulating cock that uses in coke oven heating gas pipe line, its structure is to be formed by combining by shell, fuse, spring flap, spring, hold-down bolt, clean-out hatch flap.When this cock coking time in the heating process of coke oven changes greatly, can regulate the flow of coal gas, to adapt to the needs that coke oven is produced.But gas leakage easily takes place in this cock in operating process, befouling environment, and the explosion of fire damp accident even can take place in harm operator's physical and mental health, breaking-up equipment and causing casualties.
Summary of the invention
In order to remedy existing these defectives of regulating cock, the utility model designs a kind of novel regulating cock of coke oven blast furnace gas.This cock is to it is characterized in that by shell, fuse, spring capping, oil the core body oil duct outside of regulating cock is provided with groove, and be provided with the software pipe joint in the housing outside of itself and groove corresponding position, it can be connected with negative-pressure pipeline with flexible pipe, is forbidden to scribble drier oil in its groove.
This regulating cock advantage is to prevent gas leakage and generation on fire from explosion, avoids casualties and device damage.
Description of drawings
Accompanying drawing 1 is the regulating cock front view.
Wherein 1 for the cock shell, 2 for the fuse of cock, 3 be spring, 4 for spring capping, 5 for hold-down bolt, 6 for clean out cover, 9 for oil duct, 10 be gas exit for groove, 11 is gas entry, 12.
Fig. 2 is the side view of regulating cock.
Wherein 7 is that software pipe joint, 8 is pad.
Embodiment
On the coke oven heating pipe, install have shell 1, the regulating cock of fuse 2, spring 3, spring capping 4, hold-down bolt 5, clean out cover 6, software pipe joint 7, pad 8, oil duct 9, groove 10.Because the regulating cock two ends are to be connected by flange, coal gas is easily revealed.But because regulating cock internal channel 10 links to each other with hose coupling 7, hose coupling 7 is connected with negative-pressure pipeline under the coke oven conditions of manufacture by flexible pipe.At this moment the coal gas of Guo Luing imports the coal gas upward flow voluntarily by change-over cock again and goes into the stove burning through regenerator because negative pressure just enters negative-pressure pipeline by groove 10 by hose coupling 7.
