Abstract
The utility model relates to a device for ensuring the sealing of a gas cock for a coke oven, which comprises a cock valve, a grease distributor, a grease supply main pipe and a grease distributing pipe, wherein the inlet end of the grease distributor is connected with the grease supply main pipe, the outlet end of the grease distributor is connected with the grease distributing pipe, the peripheries of two ends of a conical valve core of the cock valve are respectively provided with an annular sealing groove, a grease through hole is arranged on a shell of the cock valve and respectively corresponds to the two annular sealing grooves, the grease distributing pipe is connected with the grease through hole through a pipe joint, and grease is introduced into the annular sealing grooves. The utility model seals the gas in the plug valve, avoids the leakage of the coke oven basement gas plug valve and avoids the occurrence of safety accidents.
Description
Technical Field
The utility model relates to the field of coke oven coking production, in particular to a device for ensuring the sealing of a gas cock for a coke oven.
Background
The gas leakage of the basement of the coke oven is caused by the non-tight sealing of a cock valve of a coke oven heating system, or accidents such as the grinding of the cock, the removal of a cock handle, the jacking of an exchange brace, the influence on heating, even the occurrence of fire and the like occur in the coke oven because the oil supply of individual heating cocks is not smooth.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a device for ensuring the sealing of a gas plug for a coke oven, and avoiding safety accidents caused by gas leakage of the gas plug.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a guarantee sealed device of coal gas cock for coke oven, includes plug valve, grease distributor, grease supply house steward, grease distributing pipe, the grease distributing pipe is connected to the entry end of grease distributor, the grease distributing pipe is connected to the exit end of grease distributor, the periphery at the both ends of the toper case of plug valve is equipped with annular seal groove respectively, be equipped with on the casing of cock valve and lead to the fat hole and correspond with two annular seal grooves respectively, the grease distributing pipe passes through the coupling and leads to the fat jogged joint, lets in the grease in the annular seal groove.
The width of the annular sealing groove is 1 cm-3 cm.
The grease pressure of the grease distribution pipe is not lower than 3 MPa.
Compared with the prior art, the utility model has the beneficial effects that:
the utility model seals the gas in the plug valve, avoids the leakage of the coke oven basement gas plug valve and avoids the occurrence of safety accidents.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural diagram of the plug valve.
In the figure: the oil-fat distribution valve comprises a plug valve 1, a fat distributor 2, an oil supply fat main pipe 3, a fat distribution pipe 4, a conical valve core 5, an annular sealing groove 6, a shell 7, a fat through hole 8 and a pipe joint 9.
Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings:
referring to fig. 1-2, a device for ensuring sealing of a coke oven gas cock comprises a cock 1, a grease distributor 2, a grease supply main pipe 3 and a grease distribution pipe 4, wherein an inlet end of the grease distributor 2 is connected with the grease supply main pipe 3, an outlet end of the grease distributor 2 is connected with the grease distribution pipe 4, the peripheries of two ends of a conical valve core 5 of the cock 1 are respectively provided with an annular sealing groove 6, a shell 7 of the cock 1 is provided with a grease through hole 8 which respectively corresponds to the two annular sealing grooves 6, and the grease distribution pipe 4 is connected with the grease through hole 8 through a pipe joint 9.
The width of the annular sealing groove 6 is 1 cm-3 cm.
The pressure of the grease in the grease distribution pipe 4 is not lower than 3 MPa.
When the cock valve is opened, the valve core of the cock valve conducts gas, when the cock valve is closed, the valve core of the cock valve cuts off the gas, part of the gas is diffused to the cavity of the cock valve, at the moment, grease in the upper-shaped sealing groove of the valve core of the cock valve forms sealing with the shell of the cock valve, the diffused gas is controlled in the cavity of the cock valve, and gas leakage of the cock valve is avoided. The safety of a coal gas operation area is ensured; the problems that the normal heating of the coke oven is influenced by the dead grinding of the cock, the removal of the cock handle and the jacking of the exchange brace are avoided.
In the above embodiments, it is obvious to those skilled in the art that the present invention can be modified and modified without departing from the principle of the present invention, and the modified and modified embodiments also fall within the protection scope of the appended claims. The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and their concepts should be equivalent or changed within the technical scope of the present invention.
