Description
Technical field
The utility model relates to mechanical design field, specifically a kind of anti-gas-leak draining duplicate protection device.
Background technique
Coal gas is one of main energy sources in people's daily life, coal gas is by line transportation, in pipe conveying procedure, gas temperature can reduce, the water that mixes in the coal gas just can get off by separating and condensing, and these condensed waters must in time discharge by hydathode is set on pipeline, otherwise the too much words meeting blocking pipe of ponding, increase the resistance that coal gas is carried, influence the normal conveying of coal gas.Run into gas pressure in addition and the breakdown phenomenon of hydathode can take place when too high, and the security incident problem that causes gas pipe line to be revealed.Therefore, occurred various coal gas anti-leak products on the market, normally adopted law of buoyancy to realize the draining leakproof at the coal gas drainer design.The structure of this coal gas drainer generally comprises housing, floating drum, housing bottom is provided with drain opening, and floating drum is positioned at the top of housing internal drainage mouth, and housing is provided with the suction port that links to each other with gas pipe line, when coming the water yield big, the buoyancy that floating drum is subjected to floats greatly, and the floating drum bottom is bigger with the space that drain opening forms, and water displacement is also bigger, and when coming tolerance big, the gas pressure that floating drum is subjected to is bigger than the buoyancy that is subjected to, and floating drum and drain opening form sealing state, but shutoff coal gas.The major defect that this structure exists is: the unsteady slip space that is produced of floating drum is bigger, and the sealing of floating drum is relatively poor to neutrality, if having bigger vibration will influence sealing on every side, produces seepage and causes seal failure.Secondly, in order to improve the design air pressure range that hydathode can bear, it is bigger that ground can be designed usually in the enclosure interior space of hydathode, therefore strengthened the volume of whole hydathode, comparatively heavy, and cost of production is higher.
The model utility content
The purpose of this utility model provides a kind of anti-gas-leak draining duplicate protection device; can not be subjected to ambient vibration and influence the effect of its draining, anti-gas-leak, safe, and also volume is less; cost of production is lower, applicable to gas pipe line and other inflammable harmful gas piping facilities.
For achieving the above object, the technical solution of the utility model is:
A kind of anti-gas-leak draining duplicate protection device comprises housing, and a side of housing is provided with the suction port that links to each other with gas pipe line, is provided with floating drum in the housing, and the bottom of housing is provided with drain opening, and the bottom of floating drum is provided with sealing plug, it is characterized in that:
The top of described floating drum is provided with outlet pipe,
The top of described housing is provided with the outlet valve that is used to adjust the housing internal air pressure,
The outside of described housing bottom is provided with antivibrator, and described antivibrator is connected with drain opening,
The outside of described antivibrator is provided with protective housing, and described protective housing links to each other with housing, and the bottom of described protective housing is provided with waste pipe.
When coming water, to come-up, it is big that the space between sealing plug and the drain opening becomes together with sealing plug for floating drum, and the water in the housing flows in the antivibrator, can flow out through protective housing, waste pipe when water overflows antivibrator, antivibrator and protective housing can be kept apart floating drum and surrounding environment; When coming the water yield big, original gas pressure raises in the housing, and portion gas can enter floating drum by outlet pipe, reduces the air pressure that housing bore; When coal gas through out-of-date, the negative pressuren zone in the housing is destroyed, slides to housing bottom under the floating drum disequilibrium, sealing plug contacts with drain opening, can realize the sealing to coal gas.
As a kind of preferred construction, also be provided with guiding device in the housing described in the utility model, described guiding device is fixedlyed connected with housing, and described floating drum can move up and down along guiding device.
As improvement, also be provided with balancing weight in the housing described in the utility model, described balancing weight is connected with floating drum.
Therefore compared with prior art, the utility model has following beneficial effect:
(1) antivibrator in the utility model and protective housing can be kept apart floating drum and surrounding environment effectively, therefore how to vibrate around and can not influence the draining leak preventing effect, Security is higher, and is applicable to gas pipe line and other inflammable harmful gas piping facilities, of many uses;
(2) outlet pipe at floating drum and top thereof in the utility model, can share the interior pressure of part because of coming the excessive housing that causes of water to increase, and outlet valve also can be adjusted the air pressure in the housing, therefore can be issued to the effect that promotes negative pressure in the situation that does not increase housing boundary dimension, can make the volume of housing do very for a short time, and weight is lighter, and cost of production is lower.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute to improper qualification of the present utility model, in the accompanying drawings:
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to qualification of the present utility model.
Be illustrated in figure 1 as the embodiment of a kind of anti-gas-leak draining duplicate protection device described in the utility model; comprise housing 1; one side of housing 1 is provided with the suction port 2 that links to each other with gas pipe line; be provided with floating drum 3 in the housing 1; the bottom of housing 3 is provided with drain opening; the bottom of floating drum 3 is provided with sealing plug 4; the top of floating drum 3 is provided with outlet pipe 31; the top of housing 1 is provided with the outlet valve 11 that is used to adjust housing 1 internal air pressure; the outside of the bottom of housing 1 is provided with antivibrator 5, and antivibrator 5 is connected with drain opening, and the outside of antivibrator 5 is provided with protective housing 6; protective housing links to each other with housing 1, and the bottom of protective housing 6 is provided with waste pipe 61.
