Abstract
The utility model relates to an anti gas leakage device of a gas pipe drainer, which comprises a water seal pipe of the drainer and a drain pipe of the water seal pipe outlet. A float tank is arranged in the water seal pipe; a center of the float tank has a core tank; an upper end of the core tank has water outlet holes communicated with the drain pipe; while a bottom of the core tank has hinge valve plates. The utility model has advantage of effectively preventing the gas leakage from the drainer, safe and reliable use, convenient operation and maintenance.
Description
The utility model relates to a kind of built on stilts drainage equipment that lays gas pipe line, the gas pipeline drainer gas leakage preventing device of particularly a kind of effective sealing and draining.
In the prior art, the built on stilts gas pipe line that lays is equipped with hydathode.It is that the gas pipe line below is communicated with a vertical intubate and is communicated with a hydathode, and the vertically arranged water sealing (sealing water) pipe that makes progress is arranged on the hydathode, and the outlet of water sealing (sealing water) pipe upper end is communicated with a waste pipe.Height difference between its vertical intubate lower end mouth and the water sealing (sealing water) pipe outlet constitutes the water seal effective height, design this water seal effective height according to the gas pressure that transmits in the gas pipe line, water filling in the hydathode, just can prevent that coal gas from releasing through hydathode, and the water of condensation in the gas pipe line can be discharged through hydathode.But there is following shortcoming in existing hydathode: because the gas pressure in the gas pipe line changes, the water sealing (sealing water) pipe water level of hydathode is reduced, the proper functioning up to destroying hydathode leaks a large amount of coal gas, causes accident to leak the coal gas.Because water level just is difficult to observation in the hydathode water sealing (sealing water) pipe, causes difficulty to operation maintenance.
The purpose of this utility model is to provide a kind of gas pipeline drainer gas leakage preventing device, can effectively prevent from the hydathode leakage gas, and is safe and reliable, and operation maintenance is convenient.
For achieving the above object, the utility model adopts following technical proposals:
A kind of gas pipeline drainer leakage preventer, comprise the water sealing (sealing water) pipe of hydathode and the waste pipe of water sealing (sealing water) pipe outlet, it is characterized in that settling a floating drum in the water sealing (sealing water) pipe that there is a core tube at the floating drum center, there is osculum communicated drainage pipe the upper end portion of core tube, and there is the hinge type valve plate core tube bottom surface.
Water sealing (sealing water) pipe outlet port inner chamber has back-up ring, between back-up ring and the floating drum end face seal ring is arranged, and on the hinge type valve plate seal ring is arranged.
Fix a hinge type valve plate positioning block below the floating drum.
Core tube end face connects a floating drum mark post, and the ring endoporus cunning that floating drum mark post and water sealing (sealing water) pipe top floor support is joined, and positioning ring is arranged at floating drum mark post top.
The floating drum mark post is a hollow tubule, valve plate mark post of configuration in it, and end in contact hinge type valve plate under the valve rod mark post, there is positioning head the upper end.
Water sealing (sealing water) pipe top settles the pipeline section of floating drum to separate with lower tubular section and be connected with flange.
The utility model compared with prior art, have following conspicuous characteristics and advantage: in the utility model, settle a floating drum in the water sealing (sealing water) pipe, there is the hinge type valve plate floating drum core tube bottom surface, when destroying effective water seal of hydathode when the increase suddenly of gas pressure in the pipeline, under the effect of coal gas impact force, make the closed core tube import that makes progress of hinge type valve plate, thereby stop coal gas outwards to release.Be provided with the floating drum mark post in the utility model, then can observe the position of floating drum at any time, also promptly can observe water level in the water sealing (sealing water) pipe, can in water sealing (sealing water) pipe, inject water in case of necessity, to guarantee effective water seal water level.The valve plate mark post is arranged in the floating drum mark post, can observe valve plate and open and close state.Water sealing (sealing water) pipe top settles the pipeline section of floating drum to separate with lower tubular section and be connected with flange, is convenient to dismantle maintenance.The utility model can prevent effectively that from the hydathode leakage gas safe and reliable, operation maintenance is convenient.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the mounting structure schematic representation of the gas pipeline drainer of prior art.
Fig. 2 is an embodiment's of the utility model a mounting structure schematic representation.
Fig. 3 is an embodiment's of the utility model a structural representation (A place partial enlarged drawing among Fig. 2).
Fig. 1 illustrates the mounting structure of the gas pipeline drainer of prior art, gas pipe line 1 below is communicated with a vertical intubate 3 and is communicated with a hydathode 6, on the vertical intubate 3 two gate valves 2,7 are arranged, the vertical water sealing (sealing water) pipe 5 that makes progress is arranged on the hydathode 6, and the outlet of water sealing (sealing water) pipe 5 upper ends is communicated with a waste pipe 4.Height difference H between vertical tube 3 lower end mouth and water sealing (sealing water) pipe 5 outlets constitutes the water seal effective height.
An optimum implementation of the present utility model is: referring to Fig. 2 and Fig. 8, this gas pipeline drainer gas leakage preventing device includes the water sealing (sealing water) pipe 5 of hydathode 6 and the waste pipe 4 of water sealing (sealing water) pipe 5 outlets, settle a floating drum 17 in the water sealing (sealing water) pipe 5, there is a core tube 18 at floating drum 17 centers, there are osculum 14 communicated drainage pipes 4 upper end portion of core tube 18, and there is hinge type valve plate 21 core tube 18 bottom surfaces.Water sealing (sealing water) pipe 5 outlet port inner chambers have back-up ring 15, between back-up ring 15 and floating drum 17 end faces seal ring 16 are arranged, and seal ring 20 is arranged on the hinge type valve plate 21.Fix a hinge type valve plate positioning block 22 below the floating drum 17.Core tube 18 end faces connect a floating drum mark post 11, and floating drum mark post 11 is joined with the ring 12 endoporus cunnings that water sealing (sealing water) pipe 5 top floors 13 support, and floating drum mark post 11 tip portion have positioning ring 9.Floating drum mark post 11 is a hollow tubule, valve plate mark post 10 of configuration in it, and 10 times end in contact hinge types of valve plate mark post valve plate 21, there is positioning head 8 upper end.Water sealing (sealing water) pipe 5 tops settle the pipeline section of floating drum 17 to separate with lower tubular section and be connected with flange 19.
