Abstract
The utility model relates to a drainage device for a steam heating system, which comprises a drain valve and a stop valve communicated with the drain valve; a by-pass pipeline is connected in parallel with a pipeline communicating the drain valve and the stop valve; and the by-pass pipeline and the axial section of the drain valve are positioned at the same plane. The utility model mainly provides the drainage device for a steam heating system, which is capable of effectively speeding up the drainage of the steam heating system to prevent steam leakage and solves the technical problems of slow drainage of the drainage device in the steam heating system and easy leakage of steam from a bypass existing in the prior art.
Description
Technical field
The utility model relates to a kind of drainage means of steam-heating system.
Background technique
In the low pressure steam heating system, drainage means is absolutely necessary.And in drainage means, drain valve being installed all generally now, drain valve plays the effect of block steam and drain water do in steam-heating system, select suitable drain valve, can make steam-heating apparatus reach the highest working efficiency.Also have much about the patent of improving drain valve in the steam-heating system, as Chinese patent: " all pressing continuous drainage formula Automatic steam trap Trap (patent No. is 99221861.6) " etc., all be that the structure of drain valve inside is improved, thereby reach the purpose of increasing work efficiency with this.But in the drainage means of steam-heating system, whether the installation of drain valve also is relative.Now drain valve install normally bypass is installed in the same horizontal plane of drain valve pipeline on, after water has been arranged, drain valve can be closed automatically, steam will leak out from by-pass line, make the draining resistance vapour device of drain valve and by-pass line installation at grade exist draining untimely, to normally carrying out of producing with operate and brought certain influence.
Summary of the invention
The utility model has mainly provided a kind of drainage rate that can effectively accelerate steam-heating system, prevents the drainage means of the steam-heating system of steam leakage; The drainage means drainage rate that solves in the existing in prior technology steam-heating system is slow, the technical problem that steam leaks from bypass easily.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of drainage means of steam-heating system, comprise drain valve and the stop valve that is communicated with drain valve, be parallel with by-pass line on the pipeline of described drain valve and stop valve connection, the axial cross section of described by-pass line and described drain valve is in the same plane.The drain valve facade is installed, thereby in draining, the stop valve on the by-pass line can be opened big and together draining of drain valve, accelerate drainage rate.When water had been arranged, drain valve was closed automatically, and the water in the by-pass line has also played the effect of water seal to steam, had stoped the leakage of steam.Not only improve the drainage efficiency of steam-heating system so the facade of drain valve is installed, and prevented the leakage of steam.
As preferably, the two ends of described drain valve respectively are connected with a stop valve, and the described stop valve the other end is connecting drainage pipe.Be connected with stop valve, drain valve, stop valve on the drainage pipe in turn.By-pass line in parallel on drainage pipe.The design of stop valve can prevent well that steam from leaking so that after the drain valve draining, guarantees simultaneously sealing to make drain valve be in good working order, has guaranteed best energy-saving effect, has improved economic benefit.
As preferably, described by-pass line is provided with stop valve.The design of stop valve still can not accelerated drainage rate, and drain valve can temporarily substitute drain valve and use can't use the time.
Therefore, the drainage means of a kind of steam-heating system of the present utility model is installed drain valve and by-pass line facade, the stop valve on the by-pass line can be opened big and together draining of drain valve in draining, accelerates drainage rate.When water had been arranged, drain valve was closed automatically, and the water in the by-pass line has also played the effect of water seal to steam, had stoped the leakage of steam.Not only improve the drainage efficiency of steam-heating system so the facade of drain valve is installed, and prevented the leakage of steam.
Description of drawings:
Fig. 1 is the drainage means schematic representation of original steam-heating system.
Fig. 2 is the drainage means schematic representation of steam-heating system of the present utility model.
Embodiment:
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
As shown in Figure 2, a kind of drainage means of steam-heating system comprises drainage pipe 1, and stop valve 2, drain valve 3, stop valve 4 are installed on drainage pipe 1 successively.Drainage pipe 1 is connected an end of stop valve 2, and the other end of stop valve 2 is connected the import of drain valve 3, and the outlet of drain valve 3 is connecting an end of stop valve 4, and the other end of stop valve 4 is connecting drainage pipe 1.Be parallel with by-pass line 5 on drainage pipe 1, the axial end of the mounting plane of by-pass line 5 and drain valve 3 at grade.Be provided with stop valve 6 on by-pass line 5, an end of the stop valve 2 on an end of stop valve 6 and the drainage pipe 1 is communicated with, and the other end of the stop valve 4 on the other end of stop valve 6 and the drainage pipe 1 is communicated with.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Claims (3)
1. the drainage means of a steam-heating system, comprise drain valve and the stop valve that is communicated with drain valve, be parallel with by-pass line on the pipeline of described drain valve and stop valve connection, it is characterized in that: the axial cross section of described by-pass line and described drain valve is in the same plane.
2. the drainage means of steam-heating system according to claim 1, it is characterized in that: the two ends of described drain valve respectively are connected with a stop valve, and the described stop valve the other end is connecting drainage pipe.
