Description
United States Patent 0 3,2iiiL834 DHS CHARGER FUR CGNDENSATIUN WATER Hans-Martin Papa, Bremen-Horn, Germany, assignor to Gustav F. Gerdts KG, Bremen, Germany, a corporation of Germany Filed Apr. 16, 1962, 'Ser. No. 137,517 Claims priority, application Germany, Apr. 29, 1961,

2. Claims. (Eli. 137--13) This invention relates to a discharger for condensation Water and refers more particularly to a discharger the inner chamber of which is divided by a freely movable valve plate cooperating with a sealing surface provided with escape passages into a pressure chamber and an outflow chamber, whereby when pressure in the pressure chamber is increased, the valve plate in cooperation with the sealing surface closes the inlet channel, while the outflow chamber having the shape of an annular recess formed in the sealing surfaces cooperates with the mouth or months of the outflow channel or channels.
Prior art dischargers of this type have the drawback that the opening and closing movements of the valve plate resulting from continuously repeating increases and drops in pressure caused by steam, take place during very short time periods, so that there is a great loss in steam, as well as substantial Wear of the sealing surfaces and the valve plate; furthermore, the escape passages which are often hair thin are very quickly clogged up by dirt, so that air discharge intended by the escape passages is stopped. When the apparatus is started again, for example, after stoppage or as the result of a larger supply of air, this air as well as the subsequently precipitated condensate can not be withdrawn any more due to continuing clogging. Thus the escape passages, the purpose of which is to provide for a better removal of air by rapid escape thereof during the stoppage period can not be effective any more.
An object of the present invention is to improve discharges of this type and their operation.
Another object is to improve the air removing capacity of such dischargers.
Other objects of the present invention will become apparent in the course of the following specification.
in accomplishing the objects of the present invention it was found desirable to provide a construction wherein the space constituting the pressure chamber is located below the casing block and is made overly large, its size being the greatest possible multiple but at least the double of the stroke space of the valve plate, the usual escape passages which in prior art were adapted to the small volume of the pressure chamber, being also made overly large corresponding to the increase in volume of the pressure chamber.
Due to this feature of the present invention the closing time periods of the valve plate become considerably longer, as long as steam remains. Since there is always a large supply of condensation water (water sack) in the pressure chamber of large volume located below the casing block, this water will be repeatedly changed to steam due to pressure decreases, so that a steam cushion will remain in the pressure chamber and thus closing pressure will continue to be exerted upon the valve plate so long as this evaporation is continuing and until it is terminated. This will prolong to a substantial extent the duration of the closing pressure, so that, so long as steam remains, the opening movements will be substantially decreased, resulting in a diminution of steam losses and in less Wear and tear.
An increase in the volume of the pressure chamber is also necessary in order to provide a quicker and better air removal, resulting in a further improvement of the functions of the discharger. Namely, the change in volume makes it possible to substantially increase the size of the escape passages, so that during the closing period and while steam remains, a considerably better removal of air is attained, since air can escape faster and in larger amounts through the larger passages. Furthermore, the danger that the passages may be reduced and clogged up by dirt particles is eliminated to the greatest extent, so that a considerably more reliable removal of air is attained, thereby eliminating lengthy interruptions and thus avoiding undesirable excessive cooling. The escape passages which heretofore generally had the width of so-called hair splits, can be increased with safety and without running the risk that thereby the known high opening frequencies will be again produced in the steam, which would cancel the advantages attained by an increase in volume. On the contrary, despite the increase in the size of escape passages, the desired further increase in the duration of closing periods, while steam remains, is made possible.
It was found by actual experimentation that the sizes of the escape passages can amount to at least 1.5 of their normal size, if the value 1 be used to designate the size of such passages in known thermodynamic dischargers of the usual type having pressure chambers of small volume. It was found particularly advantageous in the case of a small nominal width of inch to provide escape passages the crosssectional area of which is not less than mm.
The invention will appear more clearly from the following detailed description when taken in connection with the accompanying drawings showing, by way of example, preferred embodiments of the inventive idea.
In the drawings:
FIGURE 1 is a section through an apparatus constructed in accordance with the principles of the present invention.
FIGURE 2 is a section through a somewhat differently constructed apparatus of the present invention.
Similar parts are designated by the same numerals throu hout the various figures.
FIGURE 1 shows an apparatus having a central support or casing block 17 which carries all the other parts of the apparatus and which is provided with an inlet opening 118 and an outflow opening 19. An inlet channel 2d is connected with the inlet opening i8 through a connecting channel 23 while an outlet channel 21 is connected with the outflow opening 19 through a connecting channel 22. A hollow chamber 24 is provided above the inlet channel 20 and serves as a decanting channel which is covered from the outside by a cover 25 mounted upon the support 17.
The casing 23 containing the pressure chamber 253 is pot-like in shape and its longitudinal axis preferably coincides with the stroke axis of the valve plate.
Obviously, the pressure chamber may be made of a different form.
The cover 25 and the casing 28 which is preferably provided with flanges 39, are located opposite each other and are interconnected by clamping members or iron ties 31 which also clamp the central support 17 located between them.
The casing 28 is enclosed by a cover 32 which protects it against external temperature effects. The cover 32 is spaced from the casing 28 andthe intermediate space 33 can be filled with a suitable insulating material. The protecting cover 32 may be made of a plastic material,
sheet metal or the like, and is preferably mounted at its bottom upon a bolt 34 of the casing 23, the cover 32 being removably held by a screw .35.
To prevent as much as possible the penetration of foreign matter to the sealing surfaces 26 serving as a valve seat, and also to the escape passages, a sieve 36 is mounted in the by-pass channel 24 to serve as a dirt collector.
In accordance with the construction shown in FIGURE 2, the dirt collector 36 is located side by side with the casing 23 of the pressure chamber 29 and is approximately of the same size, thus making possible the provision of a particularly large sieve surface. The sieve 36 serving as the dirt collector is located in a pot-shaped casing 37 which is removably connected with the central support 17. A screw 38 which is introduced from the top of the central support and which is screwed into the bottom of the casing 37, is used for the attachment of the dirt collector.
Obviously, the centrally mounted screw .38 may be replaced by suitable clamping members or iron ties located outside the casing. This arrangement makes it possible to provide at the bottom of the casing 337 a blow-off valve (not shown), thus making it possible to clean from time to time the dirt collector which is subjected to operational pressure, by opening this valve. 7
The construction of FIGURE 2 provides a further simplification in manufacture, particularly as far as the play required between the parts and the possibility of exchanging the parts are concerned, in that the inflow and outflow channels 20' and 21' are located in a conically formed insert piece 39 which is mounted in a correspondincly shaped conical bore 40 of the central support. The insert piece is loosely inserted into the central support and is held in place by the casing 223' of the pressure chamber, the casing 28' pressing against the insert piece. This is accomplished by locating the cover 25 and the casing 28 directly opposite each other and by interconnecting them by clamping members or iron ties 31 in such manner that the central support is clamped between'the clamping members and that the latter press the insert piece into the conical bore. The two outlet channels 21' of the insert piece are interconnected by an annular channel 21a which communicates with the outflow opening 19 through the connecting channel 22.. 7
Obviously, it is also possible to replace the cover 25' by the dirt collector so that it will lie directly opposite the casing of the pressure chamber. In a construction of this type it is necessary to make certain that the sieve is also attached to the casing in a hanging manner and that the open inlet into the sieve is located on top, while the bottom of the sieve should be located at the lower end.
The central support is preferably rectangular in crosssection.
Otherwise, the construction and operation of this apparatus are the same as that previously described.
It is apparent that the above-described examples have been given solely by way of illustration and not by way of limitation and that they are subject to many variations and modifications Within the scope of the present invention. All such variations and modifications are to be included within the scope of the present invention.
