Abstract
The utility model relates to a new-type coke oven gas negative pressure regulation turncock for the heating gas pipeline of coke oven comprising a shell body 1, a core body 2, a nut 3, a gland 4, an oil cup 5, an oil groove 6, a core hole 7, a squarehead switch 8, a slot 9, a screw hole 10, a pipe joint 11 and a gasket 12. This utility model has the advantages of being applied in coordination with the coke oven gas negative pressure regulation turncock to realize operation under negative pressure, and; the leaked gas can be led automatically into the for combustion, which would not only enhance the utilization rate of heat energy, save energy but also ensure safe and reliable manual operation without environmental pollution; simplified design; simple operation; convenient installation; saving of investment, and; low cost.
Description
Technical field
The utility model relates to a kind of valve, especially a kind of Novel coke furnace gas negative pressure regulating cock that is used for coke oven heating gas pipe line.
Background technique
Originally the coke-stove gas regulating cock that uses at coke oven heating gas pipe line is a positive pressure operation, and its axial two ends are to the operating environment leakage gas, and befouling environment causes personal injury simultaneously easily, the lighter's gas poisoning, and the explosion of fire damp accident takes place in weight person; And waste energy.
Summary of the invention
In view of the problems referred to above that exist, the purpose of this utility model is a kind of Novel coke furnace gas negative pressure regulating cock of development, improvement by structure, be used with coke-stove gas negative pressure exchange rotary plug, realize negative-pressure operation, not only improve the heat energy utilization rate, save the energy, and guaranteed workman's handling safety, free from environmental pollution.
In order to realize the purpose of this utility model, the technical measures of taking are a kind of Novel coke furnace gas negative pressure regulating cocks of design, comprise housing 1, core body 2, nut 3, gland 4, lubricating cup 5, oil duct 6, core hole 7 and square toes switch 8, it is characterized in that also forming by groove 9, silk hole 10, pipe joint 11 and packing ring 12; Two annular grooves 9 opening on the core body 2 lay respectively at housing 1 and core for 2 on the outside of two annular oil ducts 6; Communicate with relative groove 9 respectively in two silk holes 10 that a side of housing 1 is opened, and will with the silk hole homonymy of novel coke oven gas negative pressure exchange rotary plug; Pipe joint 11 is a hollow, and intermediate is a hexagon nut shape, and one is to have externally threaded pipe, is screwed in the hole fasteningly, is lined with packing ring 12 between intermediate and the housing 1, and the other end is the pipe of conical points mouth.
The advantage of Novel coke furnace gas negative pressure regulating cock is: itself and novel coke oven gas negative pressure exchange rotary plug are used, and realize negative-pressure operation, and the coal gas that leaks can import the stove internal combustion voluntarily, not only improve the heat energy utilization rate, save the energy, and workman's handling safety is reliable, free from environmental pollution; Its design simplification, simple to operate, construction install convenience; Reduce investment outlay, cost is low.
Description of drawings
Fig. 1 analyses and observe the overall structure schematic representation for Novel coke furnace gas negative pressure regulating cock.
Fig. 2 is the right side view of Fig. 1.
As depicted in figs. 1 and 2, Novel coke furnace gas negative pressure regulating cock is made up of housing 1, core body 2, nut 3, gland 4, lubricating cup 5, oil duct 6, core hole 7, square toes switch 8, groove 9, silk hole 10, pipe joint 11 and packing ring 12.
Embodiment
Introduce detailed technology content and the operating principle and the process of Novel coke furnace gas negative pressure regulating cock in conjunction with the accompanying drawings and embodiments: housing 1 and core body 2 are two general formulas, rotation square toes switch 8 can make core hole 7 turn to, thus the coal gas of switch coke oven heating gas pipe line.On core body 2, open two annular grooves 9, lay respectively at the outside of two annular oil ducts 6 on housing 1 and the core body 2, can avoid oil in the oil duct 6 to flow into 9 li of grooves and it is sealed, be used for reclaiming the coal gas that valve body leaks; Side at housing 1 has two silk holes 10, communicate with relative groove 9 respectively, and will with the silk hole homonymy of novel coke oven gas negative pressure exchange rotary plug, be convenient to connect, achieve negative-pressure operation; Pipe joint 11 is a hollow, and intermediate is a hexagon nut shape, is convenient to tighten, and a headband has externally threaded pipe, is screwed in the hole 10 fasteningly, is lined with packing ring 12 between intermediate and the housing 1, makes it sealing, and the other end is the taper sharp nozzle tube, is convenient to be seated connecting tube.
In coke oven heating gas pipe line system, be screwed on the Novel coke furnace gas negative pressure regulating cock between the pipe joint that is screwed on the pipe joint 11 in a hole 10 and the coke-stove gas negative pressure exchange rotary plug in the hole and connect, make Novel coke furnace gas negative pressure regulating cock also realize negative-pressure operation with flexible pipe.When Novel coke furnace gas negative pressure regulating cock during leakage gas, because suction function can make the leakage gas that collects in the groove 9 enter coke-stove gas negative pressure exchange rotary plug by silk hole 10, pipe joint 11 and flexible pipe, enters the coke oven burning again in operating process.Like this, not only improved the utilization ratio of heat energy, and free from environmental pollution, guaranteed operator's personal safety.
