Abstract
The invention relates to a gas valve protection device, particularly discloses a gas regulating valve for a hot-blast stove in the ferrous metallurgy industry, and specifically relates to a leak-proof device for a gas pipeline regulating valve. The device comprises a regulating valve arranged on a gas pipeline, wherein an opening of the regulating valve is regulated by a transmission shaft driven by an external motor; the transmission shaft is fixed on a shaft sleeve base through a shaft sleeve; a shaft sleeve sealing box is arranged outside the shaft sleeve, and comprises the shaft sleeve base, a shaft sleeve frame, a bearing block and a shaft sleeve box sealing cover; an oil delivery pipe and an oil delivery valve are arranged on the shaft sleeve box sealing cover; the shaft sleeve sealing box is filled with sealing oil. According to the device, the gas leakage is prevented to ensure the environmental safety, and a good equipment lubricating function is realized to effectively prolong the service life of the regulating valve.
Description
Technical field
The present invention relates to a kind of gas valve protective gear, the gas regulator door on especially a kind of iron and steel metallurgical industry hot blast stove, specifically a kind of gas pipe line modulating valve leakage preventer.
Background technique
Iron and steel metallurgical industry provides the hot blast stove of wind-warm syndrome for blast furnace, for guaranteeing that blast furnace is used wind-warm syndrome level, during hot blast stove burning, use automatic optimizating system, fixed-amount-of-air, by regulating gas regulator aperture, control the size of coal gas amount, burn stove process need and uninterruptedly by gas regulator, regulate coal gas amount, hot-blast furnace temperature is grown steadily, cause gas regulator operation frequency too high, when burning stove almost always in switch running state, between modulating valve axle sleeve and sealed packing, will soon there is gap, coal gas will leak out from gap, cause environment gas concentration to raise, jeopardize worker's personal safety.
Summary of the invention
Object of the present invention, it is exactly the problem existing for solving prior art, and designed a kind of gas pipe line modulating valve leakage preventer, by switch valve by yellow glycerine indentation sealing space, in seal space, be full of yellow glycerine, utilize the yellow glycerine in seal space to come gap between sealed-regulating valve axle sleeve and sealed packing, reach the object that prevents gas leakage.
Technological scheme of the present invention is: a kind of leakage preventer of gas pipe line modulating valve, comprise the modulating valve being arranged on gas pipe line, modulating valve drives the aperture of transmission shaft regulating valve by external motor, described transmission shaft is fixed on axle sleeve base by axle sleeve, and the outside of described axle sleeve is provided with sleeve sealing case; Described sealed case comprises axle sleeve base, axle sleeve frame, bearing support and axle sleeve case sealing cover; Described axle sleeve case sealing cover is provided with transport pipe and fuel delivery valve; In described sleeve sealing case, be full of sealing oil.
As preferably, described axle sleeve case sealing cover is connected with axle sleeve base, axle sleeve frame, bearing support by welding, axle sleeve base, axle sleeve frame, bearing support and axle sleeve case sealing cover formation sleeve sealing case.
As preferably, described fuel delivery valve is connected with transport pipe by Luo line.
As preferably, described transport pipe is connected with axle sleeve case sealing cover by welding.
As preferably, described sleeve sealing case is square.
As preferably, described axle sleeve base, axle sleeve frame, bearing support and axle sleeve case sealing cover are the steel plate that 0.5mm is thick.
Described transport pipe is outer Luo line, and fuel delivery valve is inner thread, and both interconnect by screw thread.
As preferably, described sealing oil is yellow glycerine.
Beneficial effect of the present invention can draw by such scheme: because an axle sleeve case sealing cover is respectively welded in the space surrounding at axle sleeve base, bearing support and axle sleeve frame up and down, original cavity is formed to a seal space, again by yellow glycerine by fuel delivery valve in oil transport pipeline indentation sealing space, in space, be full of like this after yellow glycerine, just can be by gap closing between modulating valve axle sleeve and sealed packing, not only stop the leakage of coal gas, guaranteed the Security of environment, and equipment is played to good lubrication, effectively extended the working life of modulating valve.
As can be seen here, the present invention compared with prior art has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
Wherein, 1, axle sleeve base, 2, axle sleeve frame, 3, bearing support, 4, transmission shaft, 5, axle sleeve, 6, differential, 7, axle sleeve case sealing cover, 8, transport pipe, 9, fuel delivery valve, 10, yellow glycerine.
embodiment:
In order to understand better the present invention, below in conjunction with accompanying drawing, explain in detail embodiments of the present invention.
Embodiment: as shown in Figure 1, a kind of gas pipe line modulating valve leakage preventer, comprises the modulating valve being arranged on gas pipe line, and modulating valve drives transmission shaft 4 to carry out the aperture of regulating and controlling valve by external motor.Transmission shaft 4 is fixed on axle sleeve base 1 by axle sleeve 5, and axle sleeve 5 is provided with differential 6, and the outside of described axle sleeve 5 is provided with sleeve sealing case; Described sealed case comprises axle sleeve base 1, axle sleeve frame 2, bearing support 3 and axle sleeve case sealing cover 7; Above sleeve sealing lid 7, weld one section of transport pipe 8, a switch fuel delivery valve 9 is installed above transport pipe 8, yellow glycerine 10 is passed through to fuel delivery valve 9 in transport pipe 8 indentation sealing spaces.
Above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement, also should belong to protection scope of the present invention.
