Abstract
The utility model discloses a steam pipeline draining device which comprises a water tank connected with a steam pipeline through a plurality of drain pipes. A first drain valve and a blowoff valve are arranged under the water tank, and a second drain valve is mounted above the water tank. The steam pipeline draining device has the advantages of avoiding waste of steam, prolonging the service life of drain valves, simultaneously reducing the number of used drain valves, and saving cost.
Description
Technical field
The utility model relates to a kind of draining apparatus for steam conduit.
Background technique
Because the steam in the steam line is met cold meeting condensation; Can produce water,, and have water that very big consumption can be arranged the steam in the pipeline in the pipeline because the temperature of steam and the temperature of hot water have very big difference; Can stop the direct motion of steam; So steam line in certain length, need be provided with a drain pipe, guarantees the consumption of the minimum of steam.Fig. 1 is provided with the schematic representation of drain pipe for steam line, and as shown in the figure, steam line 100 is provided with a drain pipe 1 at a distance from a segment distance, and every drain pipe 1 is provided with a drain valve 2, also is provided with blowdown valve 3 simultaneously.Drain valve 2 effects are that the water of condensation in the vapour system is discharged as early as possible, prevent the leakage of steam simultaneously to greatest extent automatically.
When adopting above-mentioned hydrophobic mode, the impurity in pipeline and the steam can deposit in drain pipe 1, and the blowdown valve 3 on the drain pipe 1 is arranged on the top of drain valve 2; Therefore drain valve 2 impurity when hydrophobic can be blocked drain pipe 1; Steam improves drain valve 2 pressure in the pipeline and cause, and causes steam to escape, and makes waste of steam; And impurity blocks drain valve 2, damages drain valve easily.In addition, adopting needs on every drain pipe of above-mentioned hydrophobic mode a drain valve is installed, and makes hydrophobic cost than higher.
The model utility content
For addressing the above problem, the utility model provides a kind of draining apparatus for steam conduit, avoids impurity to the influence of drain valve and cause waste of steam.
For realizing above-mentioned purpose, the draining apparatus for steam conduit of the utility model comprises the water tank that is connected with steam line through many drain pipes, and the bottom of said water tank is provided with first drain valve and blowdown valve, and top is provided with second drain valve.
Said water tank is provided with pressure gauge.
Said water tank is made up of casing and the end cap that is positioned at tank ends.
Adopt the draining apparatus for steam conduit of the utility model, overcome the influence of impurity, avoided waste of steam, prolonged the working life of drain valve, reduced the usage quantity of drain valve simultaneously, practiced thrift cost the proper functioning generation of drain valve.
Description of drawings
Fig. 1 is the schematic representation of the hydrophobic mode of existing steam line;
Fig. 2 is the schematic representation of the draining apparatus for steam conduit of the utility model.
Embodiment
Fig. 2 is the schematic representation of the draining apparatus for steam conduit of the utility model; As shown in the figure; The draining apparatus for steam conduit of the utility model comprises the water tank 10 that links to each other with steam line through drain pipe 1; The bottom of said water tank 10 is provided with first drain valve 11 and blowdown valve 13, and top is provided with second drain valve 12.
Said water tank 10 can be that casing constitutes with the end cap that is positioned at tank ends; Said first drain valve 11, second drain valve 12 and blowdown valve 13 all can be arranged on the end cap of water tank 10; Said water tank 10 direction as shown in the figure is when mounted installed; First drain valve 11 and blowdown valve 13 are arranged at the bottom of water tank 10, and second drain valve 12 is arranged at the top of water tank 10.Said blowdown valve 13 is preferably disposed on the bottom of water tank 10, and first drain valve 11 keeps a segment distance with the bottom, avoids impurity to block said first drain valve 11.This distance can be that water tank bottom is to 1/4 of top.
Steam line links to each other with water tank 10 through many drain pipes 1; When in the steam line condensed water being arranged, just can flow in the water tank 10 through drain pipe 1; Because the volume of water tank 10 is much larger than the volume that is original drain pipe 1, if any foreign material, foreign material can sink to the bottom of water tank 10.Can pass through blowdown valve 13 blowdowns when needing blowdown.During proper functioning, hydrophobic through first drain valve 11.Stop up if any unusual or more first drain valve 11 that makes of foreign material, the condensed water that water tank is 10 li will rise, and it is hydrophobic to arrive top second drain valve, 12 beginnings, at this moment just need clear up water tank 10.Can the end cap at two ends be opened, clear up the foreign material of water tank 10 or clean first drain valve 11 just passable.
For understanding the pressure in the water tank at any time, said water tank 10 is provided with pressure gauge 14, observes water tank 10 pressure inside and changes.
Many drain pipes of steam line can link to each other with the draining apparatus for steam conduit of the utility model, and the steam trap connection of the utility model need only be installed two drain valves, have solved because the steam that single drain valve causes is escaped.Need only regularly open blowdown to blowdown valve at ordinary times, just can guarantee permanently effective use.
Claims (3)
