Abstract
The novel utility model relates to a coke oven gas negative pressure changeover cock of the refining cock oven gas-heating pipeline, consisting of a shell 1, a Core body 2, a Bolt 3, a spring 4, a Gland 5, a Oil Cup 6, an oil passageway 7, a Trench 8, an exchange lever 9, a hole for de-carbonization 10, an entrance for air 11, a leading hole 12, a thread eye 13, a pipe joint 14, and a Gasket 15. The utility model has the advantages that the novel coke oven gas negative pressure changeover cock is engaged with the novel coke oven gas negative pressure regulating cock to achieve the negative pressure operation for both of them so that the system of the refining cock oven gas-heating pipeline does not leak out gas and thus does not pollute the environment; the utility is safe and reliable to operate so as to improve the rate of the energy use and is able to save the investment and to reduce the costs, greatly enhancing the economic efficiency.
Description
Technical field
The utility model relates to a kind of valve, especially a kind of novel coke oven gas negative pressure exchange rotary plug of pit kiln heating gas line.
Technical background
The patented technology that the inventor is original: " coke-oven gas negative pressure exchange rotary plug " utilizes the heat buoyancy that produces under the coke oven normal operating condition to realize negative-pressure operation, add three way type shell that has the de-carbon hole and the structure that has the two general formula core bodys of leading back hole, air intake opening and groove, make it solve the problem of gas leak, with the coal-gas recovering of leaking, free from environmental pollution, the detonation phenomenon that has caused because of remaining coal gas when having prevented the valve commutation, operational safety is reliable, also improve the utilization ratio of heat energy, saved the energy.Simultaneously, because the improvement of structure, when having changed original use through type valve body, each combustion chamber needs two cover exchange rotary plug, regulating cock and orifice plate boxes, then need 132 cover exchange rotary plug, regulating cock and orifice plate boxes for 65 hole coke ovens, consumption is too big, and is very uneconomical, installs and the equal inconvenience of operation; Use coke-oven gas negative pressure exchange rotary plug to make 65 hole coke ovens only need 66 cover exchange rotary plugs, regulating cock and orifice plate box to get final product, saved half, each combustion chamber only needs cover exchange rotary plug, regulating cock and an orifice plate box, has obtained tangible economic benefit.Coke-oven gas negative pressure exchange rotary plug has solved the problem of gas leak, but matching used with it coke-oven gas regulating cock also do not have head it off, and same contaminate environment is operated dangerously, wastes energy; Therefore when improving coke-oven gas regulating cock structure, also to improve accordingly the structure of coke-oven gas negative pressure exchange rotary plug.
Summary of the invention
In view of the problems referred to above that exist, the purpose of this utility model be development a kind of can with the matching used novel coke oven gas negative pressure of coke-oven gas regulating cock exchange rotary plug, make not leakage gas of whole pit kiln water back system, free from environmental pollution, save energy, operational safety is reliable.
In order to realize the purpose of this utility model, the technical measures of taking are a kind of novel coke oven gas negative pressure exchange rotary plugs of design, comprise housing 1, core body 2, bolt 3, spring 4, gland 5, lubricating cup 6, oil duct 7, groove 8, exchange moving rod 9, de-carbon hole 10, air intake opening 11 and lead go back to hole 12, it is characterized in that also forming by silk hole 13, tube stub 14 and packing ring 15; Communicate with relative groove 8 respectively in two silk holes 13 that a side of housing 1 is opened, and will with the silk hole homonymy of Novel coke furnace gas negative pressure regulating cock; Tube stub 14 is a hollow, and intermediate is a hex-nut shape, and a headband has externally threaded pipe, is screwed in the hole 11 fasteningly, is lined with packing ring 15 between intermediate and the housing 1, and the other end is the taper sharp nozzle tube.
The advantage of novel coke oven gas negative pressure exchange rotary plug is: itself and coke-oven gas negative pressure regulating cock are used, not only make and itself realize negative-pressure operation, make Novel coke furnace gas negative pressure regulating cock also realize negative-pressure operation simultaneously, whole like this pit kiln heating gas line system is leakage gas not all, free from environmental pollution, workman's operational safety is reliable, has improved the heat energy utilization rate simultaneously, has saved the energy; Because of design simplification, the coke-oven gas negative pressure exchange rotary plug of use, coke-oven gas negative pressure regulating cock, orifice plate box reduce half, and simple to operate, construction install convenience has been saved investment, has reduced cost, has improved economic benefit widely.
Description of drawings
Fig. 1 analyses and observe the one-piece construction synoptic diagram for novel coke oven gas negative pressure exchange rotary plug.
Fig. 2 is the A-A sectional view among Fig. 1.
As depicted in figs. 1 and 2, this novel coke oven gas negative pressure exchange rotary plug is housing 1, core body 2, bolt 3, spring 4, gland 5, lubricating cup 6, oil duct 7, groove 8, exchange moving rod 9, de-carbon hole 10, air intake opening 11, leads go back to hole 12, and silk hole 13, tube stub 14 and packing ring 15 are formed.
Embodiment
Introduce detailed technology content and the principle of operation and the process of novel coke oven gas negative pressure exchange rotary plug in conjunction with the accompanying drawings and embodiments: housing 1 is for three way type, core body 2 is two general formulas, moving exchange moving rod 9 can switch novel coke oven gas negative pressure exchange rotary plug, and it utilizes the heat buoyancy formation negative-pressure operation condition that produces the coke oven normal operating condition under.Side at housing 1 has two silk holes 13, communicate with relative groove 8 respectively, and will with the silk hole homonymy of Novel coke furnace gas negative pressure regulating cock, being convenient to both connects, tube stub 14 is a hollow, and intermediate is a hex-nut shape, is convenient to tighten, one headband has externally threaded pipe, be screwed in the hole 13 fasteningly, be lined with packing ring 15 between intermediate and the housing 1, make it sealing, the other end is the taper sharp nozzle tube, is convenient to be seated pipe connecting.After with the tube stub connection of flexible pipe with novel coke oven gas negative pressure exchange rotary plug and Novel coke furnace gas negative pressure regulating cock, Novel coke furnace gas negative pressure regulating cock has also been realized negative-pressure operation, make not leakage gas of whole pit kiln water back system like this, free from environmental pollution, save energy, operational safety is reliable.
