Abstract
The utility model relates to a steam blast anti-scaling gas gate valve and solves the problem that tar is accumulated inside the valve to influence the successful closing of a wedge disc. The steam blast anti-scaling gas gate valve is characterized in that a gas gate valve 1 is arranged on a system pipeline; a blast side cover 2 is arranged on the lateral surface of the bottom of the valve; two steam blast pipes 3 are arranged at the lower part of the valve; a spray nozzle is aligned with a lower cavity of the valve; a check valve 4 is connected on a blast pipe flange; a blast branch pipe 5 is arranged between a blast pipe 3 and a dirt storage box 7; a check valve 6 is arranged at the middle part of the blast branch pipe 5; a ball valve 8 is arranged between the blast side cover 2 and the dirt storage box 7; a screw conveying mechanism 9 is arranged at an outlet at the lower part of the dirt storage box 7; and a ball valve 10 is arranged at an outlet of the screw conveying mechanism 9. The steam blast anti-scaling gas gate valve has the advantages of convenience in blowdown and no gas leakage and is suitable to use as a start and stop device on a tar-containing gas pipeline.
Description
Technical field:
The invention belongs to the technical field that Double-shutter gas gate valve is made, be specifically related to a kind of steam blast good antiscale property shape coal-gas gate valve.Be applicable to contain on the pitch coal air pipe and use as start-stop device.Be widely used in industries such as controlling gold, coking.The present invention can effectively eliminate the adverse effect that the depressed dirt of pitch coal produces valve closing.
Background technique:
Existing pair of its sealed nature of plate gas gate valve belongs to forced seal, and required sealing force is large.But existing industrial coal air lock valve is applied on the coking project mostly, and its medium that passes through is for containing tar coal gas.Tar is that coal produces in coking, and its output accounts for 3%～4% of shove charge coal, and its product is black viscous fluid shape at normal temperatures and pressures, has special stink.Because the existence of this coal tar oil, long-term accumulation is in the groove bottom of industrial coal air lock valve.Especially for the valve that is in long-term opening state, this coal tar oil occupies large quantity space in the long-term accumulation of valve cavity of resorption, and then affects closing smoothly of gas gate valve flashboard, sometimes even can't close.This invention proposes for head it off just.
Summary of the invention:
Purpose of the present invention is exactly in order to overcome above deficiency, and a kind of valve cavity of resorption accumulation coal tar oil of can removing at any time is provided, and guarantees under the smooth lock of gas gate valve flashboard the steam blast good antiscale property shape coal-gas gate valve of safety shutdown.
Technological scheme of the present invention is to realize like this, described steam blast good antiscale property shape coal-gas gate valve, by gas gate valve 1, winding-up side cover 2, steam blast pipe 3 (2 cover), stop valve 4, winding-up arm 5, stop valve 6, dirt storage box 7, ball valve 8, spiral conveying mechanism 9, ball valve 10 forms, it is characterized in that gas gate valve 1 is installed on the system pipeline, winding-up side cover 2 is installed in the valve bottom sides, two steam blast pipes 3 are installed in the valve bottom, nozzle alignment valve cavity of resorption, stop valve 4 is connected on the injection tube flange, winding-up arm 5 is installed between injection tube 3 and the dirt storage box 7, stop valve 6 is installed at winding-up arm 5 middle parts, and ball valve 8 is installed between winding-up side cover 2 and the dirt storage box 7.Dirt storage box 7 lower exits are installed spiral conveying mechanism 9, ball valve 10 is installed in the outlet port of spiral conveying mechanism 9, its working principle is, when the gas gate valve on being installed in pipeline is in opening state, in the pipeline in the coal gas contained tar accumulate gradually at the valve cavity of resorption and when piling up a large amount of tar dirt, opening stop valve 4, adding the nozzle of steam by steam blast pipe 3 blows to coal tar oil that the valve body cavity of resorption piles up and it is dissolved be flowable liquid state, open simultaneously the ball valve 8 of installing on the winding-up side cover, make the tar that dissolves flow into (being blown into) dirt storage box, stay for some time, start spiral conveying mechanism 9, close ball valve 8, close two stop valves 4, opening stop valve 6, open ball valve 10, make high-temperature steam be blown into dirt storage box, tar liquid is through spiral conveying mechanism 9 in the dirt storage box, ball valve 10 flows into on-the-spot pollution discharge pond behind the external on-the-spot pipeline.Above-mentioned working procedure can regularly be carried out once.So can make in the valve, especially the valve cavity of resorption no longer includes the coal tar oil deposit, and it is normal to guarantee that the gas gate valve complete machine opens and closes.
Steam blast good antiscale property shape coal-gas gate valve of the present utility model, main feature is regularly successively several valves and spiral conveying mechanism in the operating device, can make the tar deposit of original easily fouling place of gas valve be become liquid by high temperature band pressure steam heating, and open and close successively two ball valves and spiral conveying mechanism, can make valve internal pile up tar is discharged to outside the valve body, simultaneously, coal gas can not leak in the atmosphere in the body cavity (or main line).Guarantee that coal gas can not leak outside.
Steam blast good antiscale property shape coal-gas gate valve of the present utility model is compared with traditional gas gate valve, and the present invention mainly contains following useful effect.
The effect of bringing mainly contains the dirt eliminating function that (1) has increased valve, makes valve opening and closing more flexible.(2) mechanism operation is easy, realizes easily automation.
Steam blast good antiscale property shape coal-gas gate valve of the present utility model has conveniently than the Double-shutter gas gate valve blowdown, and in the blowdown process, does not have the advantage of the leakage of coal gas.
