Abstract
The utility model relates to a drainage leak stoppage gas valve. The drainage leak stoppage gas valve comprises a cylinder, a jet pipe, a floating ball, an overflow opening baffle, a valve rod and an overflow tube, one end of the jet pipe stretches into the cylinder, the floating ball is arranged in the cylinder, one end of the valve rod is fixed to the floating ball, the other end of the valve rod is fixedly connected with a counterweight, the overflow opening baffle is fixed onto the middle portion of the cylinder, a sealing ring is fixed onto the valve rod and matches with an overflow opening of the overflow opening baffle in a sealing mode, the cylinder is connected with the overflow tube through a communication pipe arranged on the lower portion of the cylinder, and the pipe wall of the jet pipe, which stretches into the cylinder, is provided with a jet hole. The drainage leak stoppage gas valve has the advantage of achieving the safe and reliable operation of a gas pipeline due to the fact that condensate water in toxic gas can be discharged as well as obtaining sensitive and reliable opening and closing of the sealing ring so as to effectively improve the security of the operation of the pipeline and greatly protect lives and property safety of people.
Description
Technical field
The utility model relates to a kind of gas leakage device that prevents, relates in particular to a kind of draining leak-stopping gas valve.
Background technique
At present, iron and steel enterprise, in steel-making, ironmaking, coking production process, pays the most of wet dedusting technique that adopts of dust removal process of the coal gas of converter, blast furnace gas and the coke-stove gas that produce.Contain water vapour in saturated coal gas after the employing wet scrubbing, in course of conveying, water vapour can form condensed water, by being located at seal tank in gas pipe line, discharges these condensed waters.The seal tank design principle is that the water seal height produced by the dividing plate in groove is greater than gas pressure, and then reaches continuous drainage and can seal the safety installations of gas leakage again.After operation for many years, the dividing plate corrosion-vulnerable of seal tank or puncture, coal gas easily runs and leaks coal gas and cause security incident by the aperture after puncturing.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of water that can get rid of in coal gas, can seal again the safe and reliable draining leak-stopping gas valve of gas leakage.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of draining leak-stopping gas valve, comprise that cylindrical shell, an end stretch into jet pipe, ball float, overflow hole baffle plate, valve rod, the overflow cylinder in cylindrical shell, be provided with ball float in cylindrical shell, valve rod one end and ball float are fixed, the other end is fixedly connected with counterweight, the overflow hole plate washer is fixed on the cylindrical shell middle part, seal ring is fixed on valve rod, the overflow hole of seal ring and overflow hole plate washer is for being sealed and matched, cylindrical shell is connected by the connecting tube that is arranged on the cylindrical shell bottom with overflow cylinder, and the described jet pipe tube wall stretched in cylindrical shell is provided with jet hole.
Described valve rod is spacing by the locating stud be fixed in cylindrical shell.
Described overflow hole, seal ring, ball float, valve rod coaxially arrange.
Compared with prior art, the beneficial effects of the utility model are:
Realize gas pipe line safety, reliable operation, can get rid of the condensed water in toxic gas; Seal ring opens and closes and to be active in one's movements reliably, and the Security that effectively improves pipe network operation, greatly protect the people's life and property safety.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-cylindrical shell 2-jet pipe 3-ball float 4-counterweight 5-valve rod 6-seal ring 7-overflow hole baffle plate 8-locating stud 9-overflow cylinder 10-connecting tube.
Embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following mode of execution.
See Fig. 1, a kind of draining leak-stopping gas valve, comprise that cylindrical shell 1, an end stretch into jet pipe 2, ball float 3, overflow hole baffle plate 7, valve rod 5, the overflow cylinder 9 in cylindrical shell 1, be provided with ball float 3 in cylindrical shell 1, valve rod 5 one ends and ball float 3 are fixing, the other end is fixedly connected with counterweight 4, overflow hole plate washer 7 is fixed on cylindrical shell 1 middle part, seal ring 6 is fixed on valve rod 5, the overflow hole of seal ring 6 and overflow hole plate washer 7 is for being sealed and matched, cylindrical shell 1 is connected by the connecting tube 10 that is arranged on cylindrical shell 1 bottom with overflow cylinder 9, and described jet pipe 2 tube walls that stretch in cylindrical shell 1 are provided with jet hole.
Described valve rod 5 is spacing by the locating stud 8 be fixed in cylindrical shell 1.
Described overflow hole, seal ring 6, ball float 3, valve rod 5 coaxially arrange.
Between described ball float 3, valve rod 5, seal ring 6 and overflow hole baffle plate 7 for movingly.Between seal ring 6 and overflow hole baffle plate 7 for being sealed and matched.Valve rod 5 end establishings weigh 4.
During use, draining leak-stopping gas valve is arranged on to the outlet port of seal tank, jet pipe 2 is connected with the outer pipe of seal tank.Condensed water in coal gas or toxic gas sprays into cylindrical shell 1 when interior by jet pipe 2, and the ball float 3 in cylindrical shell 1 upwards promotes and hold up valve rod 5 and seal ring 6 under the effect of buoyancy, and now, overflow hole is unlocked, and condensed water is discharged by overflow hole; While in coal gas or toxic gas pipeline, there is no condensed water, ball float 3, valve rod 5 and seal ring 6 are under Action of Gravity Field, downward along locating stud 8, make the sealing that closely cooperates of seal ring on valve rod 56 and overflow hole baffle plate 7, to reach the purpose of sealing coal gas or toxic gas leakage.
The utility model, based on the law of buoyancy principle, utilizes the different specific weight of aqueous vapor and the kinetic characteristic of ball float 3 to design and produce, simple in structure, without safe, reliable, quick a kind of draining leak-stopping gas valve of external motivational drive valve open/close.The buoyancy be subject to along with the increase ball float 3 of water displacement is just larger, band ovable valve stem 5 upwards after, the water displacement of overflow hole is also large; Otherwise the buoyancy be subject to along with the minimizing ball float 3 of water displacement is just little, band ovable valve stem 5 downwards after, the sealed speed of overflow hole is accelerated, the harmful gas that may reveal is by effective sealing.Toxic gas is leaked in the draining blocking-up that is applied to the industries such as iron and steel, petrochemical industry, town gas.
The utility model has been realized gas pipe line safety, reliable operation, can get rid of the condensed water in toxic gas; Seal ring opens and closes and to be active in one's movements reliably, and the Security that effectively improves pipe network operation, greatly protect the people's life and property safety.
