Swim up your condensation

The invention relates to a float-controlled condensate drain, especially for gas and steam pipes by making a combination between float drain and thermal arrester used.

With the previously known condensate drains and steam traps Different approaches are used for the derivation. Either with the help of a valve disc, which is through a arranged storage space is braked when opening and preferably a channel in the annular surface of the web is arranged radially. As a result, the valve disc cannot suck itself onto the storage chamber, but it occurs The effect is that the braking effect on the valve disk is changed and the interval time can thus be measured. Another variant is that a bi-metal bird is applied. This bi-metal handle is on both of them Slit in linden and attached to the valve stem above and below, γ / whether the Bi-Met all bracket is bent as a circle » There is also a thermally controlled float Arrester with which there is no mass savings despite the combination of two arrester systems in one arrester Downsizing of the surface is coming. Since the losses caused by the closing organs and the control system added, the economic efficiency of the arrester was very much called into question. Also the well-known float drains with their Ableitorj; anen only limited pressure

The disadvantages of all the arresters listed are: that the AbI: it or an au large volume and thus "a large i.Iasse bü ^ öbi ^ on, which in turn leads to great radiation losses leads, itei dor üouba; e der Ableibei · must through the to high weight from Bi c he ri Lei tu. also establish brackets

be attached. Maintenance of the arresters is very difficult and time-consuming. aside from that Most of the traps do not have automatic venting. All of these fairfcores drive to a relative high price of the well-known arresters,

The purpose of the invention is to create an arrester in which the listed deficiencies are eliminated, an economically justified consumption of material is achieved and operational reliability is increased.

The invention is based on the object of an arrester in which the surface and weight are achieved by saving material (Imported material) is radically reduced, thereby reducing the price. This arrester should be universally usable for steam and gas, while at the same time the highest possible Maintenance-free and higher operational safety is guaranteed. The arrester is constructed according to a modular system, since through standardization float and thermally controlled drainage organs in one Housing can be accommodated, resulting in an absolute improvement in the economics of the Arrester leads.

According to the invention this is achieved in that a through the float as a level regulator operated cone valve, the control room via the inlet opening and the Outlet chamber in one level with the valve disc, provided with a relief valve, with the condensate amiae Ir aum connects according to the amount of condensate or complete. The advantages of the steam trap lie in the fact that the agreements and daiidb connected the entire lateral area of the diverter is reduced to oin! minimum, and the arrester is over

The entire pressure range works without any special setting. This trap still works perfectly at counter pressures of 90 - 95% of the inlet pressure. In addition, the trap only opens or closes when condensate or steam accumulates. It can also be used for draining non-aggressive gases The radiation losses and losses through the closing element drop to a fraction of the previously known values.

In contrast to the well-known α float drains, the new condensate drain can save. approx. 30-50 ; l cast and approx. 70-90 % stainless steel sheet can be achieved. This also means that the arrester can be built according to the modular principle. This means that either a float valve or a thermal valve can be installed in one and the same housing. In contrast to float drains, the condensate drain works perfectly in the entire low pressure range 0-16 atm. The setting for the operating conditions required for thermal arresters and for stepped nozzle arresters is not required. The condensate drain can be installed self-supporting in the pipe system.

The invention is to be explained in more detail below using an exemplary embodiment.

The float 6 located in the condensate sainmelraum 10 controls the conical valve 13 firmly attached to the float 6, the conical seat 7 and the ball check valve 8 in the control chamber 9, so that when steam is present, the control chamber 9 * & it is connected to the condensate collection chamber 10, and the pressure is fully maintained in the control room 9 "In _{the event of condensation, the float cone 16 closes the passage from the condensate collection chamber 10 to the control room 9 f} whereby the pressure in the control room 9 is reduced through P through the outlet valve 15 in the valve disk 4" If the pressure reduction in the control room 9 has progressed sufficiently, so the valve plate 4 lifts from the valve seat 14 - and the connection drive channel 17 - outlet chamber 11 - outlet 18 is released. The outflowing condensate lowers the condensate level in the condensate collection space 10 * the float cone 16 releases the condensate collection space connection 10 and the control space 9 and the work cycle begins vco. new. When the float 6 is replaced with a RLJfe tall valve 5, the work cycles are the same, with the difference that the cone valve 13 which closes the condensate collection chamber 10 and the control chamber is thermally actuated by a double ball 12.
