Description
Technical field
The utility model relates to a kind of natural valve station pipeline heating mechanisms.
Background technique
Due to needing layering to be depressured during natural gas supply, need to absorb a large amount of thermal energy in the process.Therefore, in this process
Middle pipe surface produces serious frost, because of demand of absorbing heat to eliminate this hidden danger.Pass through station internally heated oven pair at present
The mode that cryogenic gas carries out indirect heating in pipeline is alleviated, and effect is more obvious；However, due to the natural gas in pipeline
What flow was not constant between, when flow is larger, it is desirable to provide heat it is more, when flow is smaller, it is desirable to provide heat
Measure smaller, and the supply of prior art thermal medium is invariable, therefore while lead to natural pressure fluctuation in pipeline
Partial heat is caused to waste.
Summary of the invention
The utility model aim is to solve the above problems, and provides a kind of natural valve station pipeline heating mechanism, specifically by
Following technical scheme is realized:
A kind of natural valve station pipeline heating mechanism, including heater box, a pair of of hot water cover and runoff investigation unit, it is described
Heater box is serially connected in gas pipeline, and a pair of of hot water cover fixation covers on the upside two sides of the heater box, thus plus
Hot hydroecium is formed between the upside two sides outer wall of hot tank and the inner wall of corresponding hot water cover, the side of the hot water cover is provided with and institute
The water inlet pipe of hot hydroecium's connection is stated, the other side of hot water cover is provided with the outlet pipe being connected to the hot hydroecium, the water tune
Section unit is connect with the outlet pipe.
The natural valve station pipeline heating mechanism, further design is that the outer wall of the heater box is equidistant
Several first fins are fixedly connected with, the hot water cover is provided with several second fins, and the first fin, the second fin are mutual
It is interspersed.
The natural valve station pipeline heating mechanism, further design is, the runoff investigation unit includes one
Hollow ball and a spherical envelope, the outer diameter of the spherical envelope are less than the internal diameter of the hollow ball, and the spherical envelope is set
In in the hollow ball；When the water flowed out from hot water cover enters hollow ball, if temperature is higher than spherical envelope internal gas
Temperature, then the gas heat absorption expansion in spherical envelope, thus reduce the clearance space between hollow ball and spherical envelope, thus
Increase water resistance, reduces water flow.
The natural valve station pipeline heating mechanism, further design is that the hollow ball is by two hemisphere
The shell of shape docks.
The natural valve station pipeline heating mechanism, further design is, the heater box is that thickness is less than day
The flat structure of right air pipe.
The utility model has the beneficial effects that:
It is heated using the natural gas after the decompression in the heated case of hot water cover convection current, thus after preventing natural gas from entering
Make pipeline since the frosting even deformation that is cooled leads to pipeline leakage when continuous pipeline, has the characteristics that heating efficiency is high；Passing through will
Heater box is set as flat structure, and by the first fin of setting and the second fin, improves rate of heat exchange；By the way that water is arranged
Amount adjusts unit, when the hot water residual temperature for participating in heat exchange remains unchanged higher, increases the water resistance of hot water line, reduces hot water supply
Amount, it is ensured that be layered the stability of decompression, and more energy saving.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Fig. 2 is the side view schematic diagram of heater box.
Specific embodiment
The utility model is further described below in conjunction with Figure of description and embodiment:
A kind of natural valve station pipeline heating mechanism as shown in the figure, including heater box 1, a pair of of hot water cover 2 and water
Unit 3 is adjusted, the heater box is serially connected in gas pipeline, the fixed upside two for covering at the heater box of a pair of of hot water cover
On side, so that hot hydroecium is formed between the upside two sides outer wall of heater box and the inner wall of corresponding hot water cover, the hot water cover
Side is provided with the water inlet pipe being connected to the hot hydroecium, and the other side of hot water cover is provided with the water outlet being connected to the hot hydroecium
Pipe, the runoff investigation unit are connect with the outlet pipe.
It is heated using the natural gas after the decompression in the heated case of hot water cover convection current, thus after preventing natural gas from entering
Make pipeline since the frosting even deformation that is cooled leads to pipeline leakage when continuous pipeline, has the characteristics that heating efficiency is high.
The outer wall of the heater box is equidistant to be fixedly connected with several first fins 11, and the hot water cover is provided with several
Two fins 21, and the first fin, the second fin intermesh distribution.
The runoff investigation unit 3 includes that a hollow ball 31 and a spherical envelope 32, the outer diameter of the spherical envelope are small
In the internal diameter of the hollow ball, the spherical envelope is placed in the hollow ball；The water flowed out from hot water cover enters hollow
When sphere, if temperature is higher than the temperature of spherical envelope internal gas, the gas heat absorption in spherical envelope expands, to reduce sky
Clearance space between bulbus cordis body and spherical envelope reduces water flow to increase water resistance.
Specifically, the hollow ball is docked by two hemispheric shells.In addition, as shown in Fig. 2, described add
Hot tank is the flat structure that thickness is less than gas pipeline.By setting flat structure for heater box, and by setting
The first fin and the second fin are set, rate of heat exchange is improved；By the way that runoff investigation unit is arranged, more than the hot water for participating in heat exchange
When temperature is still higher, increase the water resistance of hot water line, reduces hot water supply, it is ensured that be layered the stability of decompression, and more
Energy conservation.
