Abstract
The utility model discloses a leakage prevention gas pipeline water drainer, which comprises a cylinder body, a water drainage pipe arranged on the cylinder body, a top cover and an insertion pipe being inserted into the cylinder body. A temperature control device is arranged on a cylinder cover, a heating belt is twisted on the outer side of the cylinder body from the top to the bottom, and the heating belt is electrically connected with the temperature control device. The leakage prevention gas pipeline water drainer is characterized in that a regulation valve is arranged on the insertion pipe, a gas tester is positioned on the cylinder body, and the gas tester is connected with the regulation valve through a regulator. The leakage prevention gas pipeline water drainer has the advantages of being reasonable in structure, strong in practicability and capable of avoiding gas leakage caused by change of gas pressure.
Description
Technical field
The utility model relates to a kind of hydathode, relates in particular to a kind of anti-leak gas pipeline hydathode.
Background technique
The existing built on stilts gas pipeline that lays is equipped with hydathode.Be provided with drain opening on hydathode cylindrical shell top; Through this drain opening unnecessary condensed water in extraneous expelling tube body; Also can pass through the water filling in cylindrical shell of this drain opening; To guarantee forming effective water seal height in the cylindrical shell, the effective height according to this water seal of gas pressure design of transmitting in the gas pipeline prevents that gas from gushing through hydathode.But there is following shortcoming in existing hydathode: if the gas pressure in the pipeline continues to increase, the water seal height of hydathode is reduced, and can cause gas leakage accidents.Therefore, should provide a kind of new technological scheme to address the above problem.
The model utility content
The purpose of the utility model is: to above-mentioned deficiency, a kind of gas pipeline hydathode that can prevent to cause because of the pipeline gas variation in pressure gas leakage is provided.
For realizing above-mentioned purpose, the technological scheme that the utility model adopts is: anti-leak gas pipeline hydathode comprises cylindrical shell, is arranged at the waste pipe on the cylindrical shell; Top cover and be inserted into the intubate in the cylindrical shell, said top cover is provided with temperature controlling device, and the said cylindrical shell outside is wound with the heating tape from top to bottom; Said heating tape is electrically connected with temperature controlling device; Said intubate is provided with modulating valve, and said cylindrical shell is provided with gas detecting instrument, and this gas detecting instrument is connected with modulating valve through regulator.
The Detecting element of said detector is located in cylinder lumen top and the waste pipe.
Said modulating valve is a repid cut-off valve.
Said regulator also is provided with warning device.
The cable of said gas detecting instrument passes top cover, is fixed on top cover and the waste pipe through fixed base and clamping sleeve.
The anti-leak gas pipeline hydathode of the utility model, owing to adopt gas detecting instrument that the gas in the pipeline is monitored, if leak; Gas detecting instrument will transmit signal to regulator; Closing of regulator regulating and controlling valve avoided ducted gas leak, and manufacturing is simple, safety reliability is high; Volume is little, and the using gases pressure range is big.
The utility model has the advantages that: rational in infrastructure, practical, can prevent to cause the gas pipeline hydathode of gas leakage because of the pipeline gas variation in pressure.
