Abstract
A kind of epithelium table non-return device, comprise epithelium table body and check film, it is characterized in that: described epithelium table body arranges air intake opening and gas outlet, and described air intake opening bottom arranges draft tube, described check film is arranged at draft tube end, enters gas pipeline for anti-sealing from epithelium table draft tube.A kind of epithelium table non-return device structure of the present utility model is simple, and use safety, convenience, come in from epithelium table gas outlet when there being water, when entering gas pipeline by air intake opening, check film can be withstood closedown by water, and water is not gone out by air intake opening, can effectively avoid water to enter gas pipeline; The material of film is pvc material, and be that crushing is very little when just commonly using gas, do not affect the metering of epithelium gauge pressure, and ageing resistance is comparatively strong, life cycle is long.
Description
Technical field
The utility model relates to gas combustion apparatus field, is specifically related to a kind of epithelium table non-return device.
Background technology
We are in real life, when domestic gas-fired water heater is installed, due to water heater, erector installs error, the phenomenon accidentally water pipe being linked into gas meter, flow meter gas outlet happens occasionally, water in water pipe enters in gas pipeline by the gas outlet of combustion gas epithelium table, and then flow back to main pipeline by epithelium table, cause the water stemming of combustion gas main pipeline, bring inconvenience to safe gas.Get rid of this obstruction accident usually to need main combustible pipe road to close, drain the water in gas pipeline, use of can ventilating.The usual like this large area that needs is stopped the supple of gas or steam repairing for a long time, and not only maintenance cost is high but also bring inconvenience to community resident life.
Utility model content
Not enough for prior art, the utility model provides a kind of epithelium table non-return device, adopts during the use combustion gas of this device and can effectively avoid water to enter gas pipeline, for resident brings convenience with gas safely.
The technical scheme in the invention for solving the above technical problem is: a kind of epithelium table non-return device, comprise epithelium table body and check film, described epithelium table body arranges air intake opening and gas outlet, described air intake opening bottom arranges draft tube, described check film is arranged at draft tube end, enters gas pipeline for anti-sealing from epithelium table draft tube.
Further, the pipeline of described epithelium table draft tube end is for being horizontally disposed with.
Further, described check costal fold directly hangs on epithelium table draft tube end, can open, then close against inlet charge direction along inlet charge direction.
Further, described check film is lightweight PVC material, does not affect inlet charge.
Further, the size of described check film is greater than the size of epithelium table draft tube end air intake opening.
The advantage that the utility model possesses: a kind of epithelium table non-return device structure that the utility model provides is simple, use safety, convenience, come in from epithelium table gas outlet when there being water, when wanting to enter gas pipeline from air intake opening, check film can be withstood closedown by water, water is not gone out by air intake opening, can effectively avoid water to enter gas pipeline; The material of film is pvc material, and be that crushing is very little when just commonly using gas, do not affect the metering of epithelium gauge pressure, and ageing resistance is comparatively strong, life cycle is long.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further, as shown in Figure 1, a kind of epithelium table non-return device, comprise epithelium table body 1 and check film 2, described epithelium table body 1 arranges air intake opening 3 and gas outlet 4, described air intake opening 3 bottom arranges draft tube 5, and described check film 2 is arranged at draft tube 5 end, by draft tube 5 enters gas pipeline after entering epithelium table for anti-sealing from epithelium table gas outlet 4.
The pipeline of described epithelium table draft tube 5 end is for being horizontally disposed with; Described check film 2 vertical hanging, in epithelium table draft tube 5 end, can be opened along inlet charge direction, then close against inlet charge direction; Described check film 2 is lightweight PVC material, does not affect air intake opening 3 air inlet; The size of described check film 2 is greater than the size of epithelium table draft tube 5 end air intake opening.
Claims (5)
