The leakage-free coal gas drainer has a simple structure and high pressure resistance and saves water.
Description
Technical field
The utility model relates to a kind of hydathode, is particularly suitable for converter, blast furnace, coke oven gas pipe, in getting rid of coal gas, in the contained humidity, avoids gas leakage to cause the accident.
Background technique
Coal gas drainer is widely used in converter, blast furnace and coke oven gas pipe, when the pressure that traditional coal gas drainer mainly adopts the water level height to be produced guarantees to discharge moisture in the coal gas, avoids the leakage of coal gas; On the one hand; Because the making of water seal relation, highly impossible making is too high, and the pressure that liquid level produced also has very big restriction; The unusual coal gas high pressure that produces of pipeline might cause the puncture of hydathode, seriously jeopardizes personal safety in the surrounding environment.Simultaneously, traditional hydathode has enough water yields in order to guarantee in the water seal, must have continuously new water mend into, water resource waste is serious.
Summary of the invention
In order to overcome the shortcoming of existing technology, the utility model provides a kind of no leakage gas drainage device, and it is simple in structure, withstand voltage height, water saving.
The technological scheme that its technical problem of the utility model solution is taked is: the two ends up and down of cylindrical shell are sealing and fixing top cover and base plate respectively, the fixing coal gas drain inlet that communicates with cylinder lumen on the top cover; Sealing and fixing dividing plate in the cylindrical shell, dividing plate is divided into draining storehouse and water storage with the inner chamber of cylindrical shell, and the discharge orifice of communicated drainage storehouse and water storage is arranged at the bottom of dividing plate; The movable sealing plug is arranged in water storage on the discharge orifice, and sealing plug is fixed on the controlling rod, and the upper end of controlling rod and described dividing plate are hinged; The lower end of controlling rod can be movable along the guiding device that is fixed on the dividing plate; The middle part of controlling rod is connected with connecting rod on being hinged on cylindrical shell, and the upper end of connecting rod and the lower end of ball lever are hinged, and the upper end of ball lever is ball float fixedly; Ball lever is fixed on the cylindrical shell through slide, and ball lever can slide by easy on and off in slide; Drain opening is arranged at the top of said cylindrical shell, a little higher than ball float in vertical position of drain opening the most the next.
1), pressure resistance is high the utlity model has advantage:: when the water storage water level was lower than ball float, ball float sank to stopping up draining storehouse and water storage passage, and gas pressure is big more; Stop up tight more; Make properly, withstand voltage can reaching more than the 0.5MPa avoids coal gas to leak fully.2), practice thrift new water: this hydathode utilizes the moisture purpose that just can reach sealing coal gas in the coal gas fully, therefore, need not external new waterpipe.3), applied widely: this hydathode can be widely used in the draining of various moisture gas pipelines to be used.Different according to Environmental Conditions, can be suitable in various zones, for fear of in the freezing damage of north cold area, hydathode inside can install independently steam-heated pipe line additional.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Accompanying drawing is the utility model structural representation.
Embodiment
Shown in accompanying drawing, the two ends up and down of cylindrical shell 7 are sealing and fixing top cover 10 and base plate 1 respectively, the fixing coal gas drain inlet 12 that communicates with cylindrical shell 7 inner chambers on the top cover 10; Steam inlet 11 fixing on the top cover 10 links to each other with independently antifreeze heating pipe in cylindrical shell according to actual use condition; Cylindrical shell 7 sealing and fixing dividing plates 6, dividing plate 6 is divided into draining storehouse 9 and water storage 13 with the inner chamber of cylindrical shell 7, and the discharge orifice of communicated drainage storehouse 9 and water storage 13 is arranged at the bottom of dividing plate 6; Sealing plug 4 is arranged in water storage 13 on the discharge orifice, and sealing plug 4 is fixed on the controlling rod 5, and the upper end of controlling rod 5 and described dividing plate 6 are hinged; The lower end of the lower end of controlling rod 5 and connecting rod 17 is hinged; The middle part of connecting rod 17 is hinged with the support 18 that is fixed on the cylindrical shell 7, and the lower end of the upper end of connecting rod 17 and ball lever 15 is hinged, and the upper end of ball lever 15 is ball float 14 fixedly; Ball lever 15 is fixed on the cylindrical shell 7 through slide 16, and ball lever 15 can slide by easy on and off in slide 16; Drain opening 8 is arranged at the top of said cylindrical shell 7, a little higher than ball float 14 in the vertical position of drain opening 8 the most the next.
For improving reliability, said ball float 14 is the light solid ball of larger volume, increases gravity on the one hand, improves the impacting force of sealing plug 4.Avoid on the other hand losing the ball float effect because spheroid damages water inlet,
For improving the impacting force of sealing plug 4, fixedly extension spring 20 between said controlling rod 5 and the dividing plate 6.
Coal gas drain inlet 12 is received the gas pipe line below, and the water in the gas pipe line will continually flow down, when water storage 13 water levels are lower than ball float 14; Ball float 14 sinks to stopping up draining storehouse and water storage passage; When the water yield was higher than ball float in water storage, the ball float come-up was opened water storage and draining storehouse passage; According to law of connected vessels, unnecessary water can flow out from drain opening.
