Abstract

A steam pipeline drainage device is used for connecting with a steam pipeline and draining condensate of the steam pipeline; the steam pipeline drainage device comprises a casing and a plug part, wherein the casing is provided with a first end part, a second end part and a perforation penetrating the first end part and the second end part; the diameter of the perforation gradually reduces from the first end part to the second end part, and the first end part is used for connecting with a steam pipeline; the plug part is arranged in the perforation and comprises a plug part body and a passageway formed in the plug part body, and the two ends of the passageway are communicated with the perforation; and the space between the two ends of the passageway extends in a linear manner or a nonlinear manner. With the passageway design of the plug part, on one hand, the condensate from the steam pipeline can be smoothly drained, and on the other hand, the steam leakage of the steam pipeline can be reduced.

Description

The steam pipework drainage means

Technical field

The utility model relates to a kind of steam pipework drainage means, particularly relates to a kind of drainage means that the condensed water discharge of steam pipework is provided.

Background technique

General steam generated within the pipeline system in order to avoid accumulation of condensed water damage caused by water hammer phenomenon pipeline component or affect system operation, will set the steam piping drainage (or called eradicates water heater / valve) for vapor lines condensed water discharge, however, due to condensation of water in the discharge process, the steam from the steam line may result with the steam discharged together with the waste outside, therefore, as China Taiwan Model Publication No. 517819 that disclosed "continuous steam condensate exclusion devices improved "for the aforementioned steam condensate escape easily with the issues raised a workaround by setting the flow through the case hole plug and outlet plugs to reach the condensation water can be properly discharged but can reduce the effect of steam leaks .

The model utility content

The purpose of the utility model provides a kind of further steam pipework drainage means of improvement.The utility model steam pipework drainage means is used to be connected in a steam pipework, provides the condensed water of this steam pipework to discharge, and this steam pipework drainage means comprises a housing and a plug part.This housing has the perforation that a first end, a second end, run through this first end and this second end, and this piercing aperture by this first end toward this second end direction convergent, this first end is used to connect this steam pipework.This plug spare is arranged in this perforation, and this plug spare comprises that a body, is formed at the runner of this body and two ends this perforation of connection.

Further, extend for non-rectilinear between these runner two ends.

Further, be straight-line extension between these plug part runner two ends.

Further, the body of this plug spare is column and has an outer circumferential face, and this runner is recessed to form in this outer circumferential face.

Further, this runner shape extension in the shape of a spiral.

Further, the perforation of this housing is a withdrawing pattern taper hole.

The beneficial effect of the utility model is: the perforation by housing is the design of taper hole; The assembly and disassembly of convenient plug part; And fill in the structural design of part runner, not only reach the effect of condensed water draining, the steam that also can reduce steam pipework releases; Thereby avoid waste of steam, and the molding mode easy processing of helical runner.

Description of drawings

Fig. 1 is the schematic side view that a preferred embodiment of the utility model steam pipework drainage means is assembled in a steam pipework;

Fig. 2 is the sectional view of this preferred embodiment, explains that a plug part is incorporated in the housing; And

Fig. 3 is the sectional view of a kind of variation in this housing of the plug spare of this preferred embodiment, and wherein, this plug spare is formed with line flowing channel in addition.

Embodiment

Below in conjunction with accompanying drawing and an embodiment the utility model is elaborated:

Consult Fig. 1 and Fig. 2; The preferred embodiment of the utility model steam pipework drainage means 100 comprises a housing 1 and a plug part 2; In the present embodiment, housing 1 roughly is straight tube-like and has the perforation 13 that a first end 11, a second end 12 and run through first end 11 and the

second end

12, and 13 the aperture of boring a hole is by the direction convergent of first end 11 toward the second ends 12; In other words; The aperture 111 of housing 1 first end 11 is greater than the aperture 121 of the second end 12, and more particularly, the perforation 13 here is a withdrawing pattern taper hole.

In addition; The outer surface that housing 1 is positioned at first end 11 and the second end 12 is respectively equipped with external thread structure; Housing 1 is that the external thread structure through its first end 11 outer surfaces is bolted in a steam pipework 3; Make the perforation 13 of housing 1 be connected with steam pipework 3, the second end 12 of housing 1 then is to be communicated with the external world.

Plug part 2 comprises that a body 21 and is formed at the runner 22 of body 21; Plug part 2 is to clog in the perforation 13 of housing 1 with its body 21; Its runner 22 is connected with perforation 13; Additional disclosure be because the perforation 13 of housing 1 is a withdrawing pattern taper hole and its aperture by the direction of the first end 11 direction convergent toward the second end 12, therefore; Body 21 is to be inserted in the perforation 13 of housing 1 by first end 11, leans on owing to perforation 13 aperture convergent can't continue to move up to body 21 to be butted on internal face that housing 1 defines perforation 13 and to be in the state of clogging in boring a hole in 13.Opposite, when needs will be filled in part 2 by housing 1 separation, plug part 2 is withdrawed from toward the direction of first ends 11 by housing 1 the second end 12 application of forces.

In the present embodiment, body 21 is column and has an outer circumferential face 211, and runner 22 is that shape is recessed to form the outer circumferential face 211 in body 21 in the shape of a spiral, and particularly, runner 22 can form through the technology of similar tapping.

When plug part 2 was clogged in the perforation 13 of housing 1, plug part 2 runners 22 two ends communication bores 13 made perforation 13 interior fluids only can pass the body 21 of plug part 2 through runner 22.

When the vapor condensation in the steam pipework 3; Condensed water can push and move and discharge via the direction of the runner of filling in part 2 22 toward the second end 12 of housings 1 by the vapor pressure in the steam pipework 3; And when condensed water is positioned at the runner 22 of body 21, owing to can take the space of runner 22, so; Also can stop the steam in more a large amount of steam pipework 3 to flow out the second end 12 via runner 22; In addition, spiral helicine runner 22 designs, the steam that also helps to stop steam pipework 3 is discharged by the second end 12 of housing 1.

What remark additionally is; The plug spare of Fig. 22 bodies 21 also can be formed with line flowing channel as shown in Figure 3 23 (the for example structure of similar Venturi tube) in addition again and cooperate this non-directional runner 22; Perhaps; The runner 22 of the plug spare of Fig. 22 does not exceed with helical, also can be as being non-directional stream between the line flowing channel 23 of Fig. 3 or other two ends.

In sum, the utility model is the design of taper hole by the perforation 13 of housing 1, the assembly and disassembly of convenient plug part 2; And the structural design of plug part 2 runners 22; Not only reach the effect of condensed water draining, the steam that also can reduce steam pipework 3 releases, thereby avoids waste of steam; So can reach the purpose of the utility model really, and molding mode easy processing of helical runner 22.

The above; Be merely the preferred embodiment of the utility model; Can not limit the scope that the utility model is implemented with this; Be that every simple equivalent of being done according to the utility model application right claimed range and model utility description changes and modifies, all still belong in the utility model claims institute restricted portion.
