Device for the automatic drainage of liquids _9, in particular condensation water from steam lines

The invention relates to a device for the automatic drainage of liquids which are in "pressurized, Collect pipelines and other cavities ^ especially for draining condensation water from steam lines «

The most well-known devices for the automatic drainage of liquids include condensate _{drains. These differ essentially in the type of drainage system and} the most common types. They are arresters with a rigid nozzle as a discharge system; with a freely movable disc as _{the closing organ s} with compulsory control of the closure organ by a float and a drain with inevitable restraint of the closure organ by a temperature-dependent pear-shaped pillar

Arrester with rigid nozzle have known no shut = organ by the leakage of steam can be completely prevented ₀ for is their isolating properties to steam condition ,, that always a minimum amount of condensation water must be present _o Its scope is therefore he "limited to Dampfaniagen where ever condensate anfällto For dl © using dei ° arrester with free "mobile disk as blocking plate must be met werö © n ₈ élass Oer pressure in the condensate line in relation stm operating pressure is not too high and ₀ that the operating pressure, a minimum height 'conditions have must avoid steam loss © wi @ rme ± den _o As a result, the area of application for this © arrester is severely restricted _{o As experience has shown that in practice "the conditions described above for the application of the b © idea P} " apply in many of the arrester types cases are not sufficiently taken into account ₅ are steam losses due to this © Ableiter di © Folg @ _o

The control element can consist of a float that adjusts to the height of the liquid level in the steam line or in another cavity, by means of which the inflow of part of the liquid to be diverted to the bellows is regulated by, for example, a cone on the float opening the inlet opening of the supply line to the The bellows consequently opens or closes in such a way that after the liquid to be diverted has drained, the inlet opening of the feed line through the cone on the float is closed when the float sinks, for example for the steam flowing in. The float may be housed in a separate float housing which a plant such as a condensate trap, this is against rotatably connected to the liquid containing portion to be derived, and * has an opening for supplying the liquid ness. Between the float housing and the float, an externally adjustable, temperature-sensitive organ, e.g.

The control element can also be an externally adjustable, temperature-sensitive element, for example a bimetallic system, which is arranged within the part of a system containing the liquid to be diverted, or outside it in a separate housing, at a suitable height to the liquid level and through the example, the Eintrlttsöffmmg the supply line is closed to the bellows by means of a cone on reaching the predetermined by the setting of the bimetal (systems the temperature of the liquid.

To avoid malfunctions on the control unit due to contamination, in the supply line to the float housing or A dirt trap is arranged in front of the bi-metal system. To the An adjustable stop is provided to limit the stroke of the shut-off valve cone and thus the flow rate. In the event that the closing of the valve cone of the shut-off valve is contrary to the direction of flow to be diverted Liquid occurs, an exchangeable spring is provided in front of or behind the valve cone through which the valve cone is preloaded «To lessen the need for opening

Closing the shut-off valve can be at any distance be arranged from each other. This makes it possible to close the shut-off valve early, i.e. before e.g. the steam has reached this

The technical progress made by the device according to the invention compared to the known devices consists in that through the indirect control of the closure organ over the control unit e.g. a condensate drain for the

ψ The largest amount of condensate to be drained and the highest operating pressure can be designed for which only a suitable size of the bellows has to be selected. The stop for limiting the stroke of the shut-off valve cone allows the trap to be adjusted to any amount of condensation water to be discharged, so that several trap sizes are not required. The shut-off valve is always completely closed by the bellows, so there is no loss of steam. Since only part of the liquid to be diverted is necessary to control the shut-off valve, the float and thus the entire diverter housing can be relatively small, so that only slight heat losses can occur due to radiation. Of course, the effective

The ability of the swimmer is reinforced by leverage will. The weight of the arrester can be so small that supports are not required. In the inventive Arrangement of a bimetal system as a control element can inadmissibly large accumulations of condensate in the steam line do not occur because the bimetal system can be arranged at a suitable height to the liquid level.

The invention is to be explained in more detail below using a few exemplary embodiments. In the accompanying drawing demonstrate:
