Description

A steam condensate drainer < RTI ID = 0.0 >

The present invention relates to a steam condensate drain.

If heat is transported away from the vapor along with the vapor pipe, condensate will be generated from the vapor. Accumulated condensate in the pipe significantly degrades system performance. Thus, the condensate must be removed from the vapor as it is produced. In a steam piping system, when the accumulated condensate is drained from the steam line, it is typically returned to the steam boiler through the condensate-return line. The condensate return line generally includes a debris strainer device that filters particulate debris. In the prior art, the condensate is discharged from the low point to the condensate return system by a mechanical vapor trap that is open when the condensate is present and closed when in the presence of steam. These traps should be regularly replaced or monitored to avoid manufacturing problems or energy losses.

Steam traps are devices that are used to discharge condensate and non-condensation gases and not to allow leakage of live steam. The earliest and simplest form of steam trap is the orifice trap. It is installed at the lowest point of the facility and thus consists of a disk with a simple drilled small hole or a short solid pipe nipple, which is known as a nozzle. The vapor condensate will be collected at the bottom, and because these hot liquids are about 1200 times smaller in volume and denser than the live vapor, the condensate is effectively removed and the vapor is blocked.

Most condensate removal devices lack means for inspecting the nozzles during operation. Inspections generally require downtime of the entire system, which results in time consumption and cost loss.

Another device for draining the vapor condensate that accumulates on the steam line as heat is lost from the steam is disclosed in U.S. Patent No. 4,171,209, wherein the condensate removal device includes a condensate removal device within a fitting body And is characterized by an orifice plate which is integrally formed and preferably located downstream from the conventional Y-strainer. The small orifice in the plate needs to be drilled to a fixed length and diameter. British Patent No. 2,088,246 discloses a filter element within a body, which is a replaceable tubular nozzle structure to allow variation of the orifice size within the standard body. However, condensate loads or pressures used for sizing have proven to be inaccurate, and replacing either the entire body or the nozzle insert of such a device requires complete removal of the section of the pipe work. The space in which the trap is installed is often limited, so the provision of a union fitting for easy removal of the trap may not be practical. Also, the cost and inconvenience of union installation means that they are not always fitted.

Thus, the present invention provides a vapor condensate drain, wherein the steam condensate drain is formed by a third cavity protruding substantially perpendicular to the inlet cavity at one end, the outlet cavity at the other end, and the axis of the inlet cavity A housing in which a fluid conduit is formed to pass through a nozzle hole between the inlet cavity and the third cavity and through a drain hole between the third cavity and the outlet cavity, a nozzle removably inserted in the nozzle hole, A nozzle having a passage, and a removable cap attached to the third cavity and spaced apart from the nozzle hole and the drain hole to seal the third cavity.

The foregoing summary is provided to provide a selection of concepts in a simplified form which will be described in more detail in the detailed description of a preferred embodiment of the present invention below. The summary is not intended to distinguish between the essential features or essential features of the claimed subject matter and is not intended to be used to determine the scope of the claimed subject matter.

These drawings depict only illustrative embodiments of the present invention and are therefore not to be considered limiting of its scope. BRIEF DESCRIPTION OF THE DRAWINGS The present invention will be further described and illustrated with additional specificity and detail through the use of the accompanying drawings in which:
1 is a plan view of an embodiment of the present invention;
2 is a front cross-sectional view of an embodiment of the present invention;
3 is a rear view of an embodiment of the present invention; And
4 is a side view of an embodiment of the present invention.

The present invention relates to a steam condensate drain. It should be noted that the following description refers to a steam condensate drain, but is not limited to any particular size or shape of the drain and is substantially capable of many sizes and shapes within the general scope of the description below. Now, reference numerals are used as numerals, and like reference numerals will be provided for like structures. It should be understood that the drawings are schematic and illustrative of certain embodiments of the present invention and that scale changes may be made as needed without limiting the present invention.

In a preferred embodiment of the present invention, the present invention relates to a vapor condensate drain. The muffler includes a housing, the housing being formed by an inlet cavity at one end of the housing and an outlet cavity at the other end, and a third cavity extending from the side of the housing vertically from the main shaft of the housing. The inlet cavity is connected to the third cavity through the nozzle hole. In addition, the third cavity is connected to the exit cavity through a drain hole. A nozzle having a narrow nozzle passage allowing fluid to flow therethrough is inserted into the nozzle hole. The diameter of the passageway is formed smaller than the diameter of the nozzle hole to allow condensate to pass through the nozzle. Next, the cap is screwed into the third cavity, and is tightened and sealed away from the nozzle hole and the drain hole to seal it. During operation, the mixture of steam and condensate under high pressure is directed from the inlet pipe to the inside of the inlet cavity. The filter chambers may be integrated and connected at an angle to the housing. The filter chamber includes a wire mesh screen filter, which is mounted cylindrically inside the filter chamber. The filter chamber is located between the inlet cavity and the nozzle orifice. The vapor condensate passes through the nozzle passage into the third cavity, through the next drain hole, and out into the exit cavity. Condensate can be directed to the steam boiler.

The present invention also relates to a housing formed by an inlet cavity at one end, an outlet cavity at the other end, and a third cavity protruding substantially perpendicular to the axis of the inlet cavity, wherein the fluid conduit is between the inlet cavity and the third cavity And through a drain hole between the third cavity and the exit cavity; A nozzle having a nozzle passage removably inserted in the nozzle hole; And a removable cap attached to the third cavity and spaced from the nozzle hole and the drain hole to seal the third cavity. A filter chamber comprising a stainless steel wire mesh filter can be positioned between the inlet cavity and the nozzle aperture such that the flow of vapor condensate from the inlet cavity to the nozzle aperture flows through the filter to filter any debris.

Inspection can be performed during operation with minimal impact on manufacturing. If the cap is open and a sharp whistling sound is heard, this means that the nozzle passage is too large to allow too much steam to pass through the exit cavity. Another recognition result is that the temperature of the branch cavity is higher than the inlet cavity, which means that the nozzle is blocked for some reason or because it is too narrow. In the present invention, clogged nozzles can be easily replaced.

Referring to Figures 1 and 2, there is shown a vapor condensate drain 10 of the present invention, which is typically connected to a steam pipe system. The steam condensate water drain 10 has a main housing 12 which is formed by an inlet cavity 20 at one end and an outlet cavity 30 at the other end and has a substantially straight cylindrical shape. The inlet cavity 20 bends and extends beyond the main housing 12 within the filter chamber 70. The filter 72 is positioned within the filter chamber 70 and is configured to limit particles and debris flowing from the inlet cavity 20. This filter chamber 70 is enclosed in a removable filter cap 80, allowing for easy replacement of the filter 72. Next, the filter chamber 70 is connected to the nozzle hole 42, and the nozzle hole 42 reaches the inside of the third cavity 40 to connect the inlet cavity 20 to the outlet cavity 30. This third cavity (40) projects vertically from the axis of the main housing (12). The nozzle 50 having the narrow nozzle passage 52 is fitted inside the nozzle hole 42. [ The third cavity 40 is further connected to the exit cavity 30 through a drain hole 46. The removable cap 60 is screwed into the third cavity 40 to seal the third cavity 40 away from the nozzle hole 42 and the drain hole 46. A thread is formed in the wall of the third cavity 40 to receive the removable cap 60 with the corresponding threaded wall 62 and to form an enclosed cavity. The cap 60 is nut shaped with a flange 64 at the top to seal the branch cavity 40.

Referring to Figs. 3 and 4, there is shown a vapor condensate drain 10 having a housing 12 at one end, including an inlet cavity 20. Fig. Inside the housing 12, this inlet cavity 20 is connected to the branching filter chamber 70 to be positioned at an angle from the inlet cavity 20. The filter chamber has a removable filter cap (80) during normal operation. The filter chamber 70 passes through the nozzle bore (not shown in any figures) to the third cavity 40. This third cavity 40 has a removable cap 60 and seals the third cavity through the threaded screw 62 during normal operation of the vapor condensate drain 10. Next, the third cavity 40 reaches the exit cavity 30 through the drain hole 46.

Referring to either of FIGS. 1, 2, 3 and 4, the operation of the vapor condensate drainer 10 will be described. The mixture of steam and condensate under pressure is introduced into the inlet cavity (20). This mixture then follows a curved surface inside the filter chamber 70 and then flows through the wire mesh filter 72, which traps the debris. This filter is an integrated strainer with a unique design of 40 x 40 mesh 0.010 inch (0.010 inch) diameter stainless steel wire mesh. The mixture of filtered vapor and condensate then meets the nozzle 50 through the narrow nozzle passage 52. The nozzle passageway (52) allows most of the liquid or vapor condensate to flow from the inlet cavity (20) to the third cavity (40). Next, the condensate enters the third cavity (40) and flows out through the drain hole (46) to the outlet cavity (30). The condensate is then conveyed to the steam boiler (not shown in any figures).

The cap 60 can be easily removed to observe the function of the nozzle 50. [ The nozzles 50 should be checked regularly and ensured to be performed at maximum efficiency. The discharge is monitored to ensure that the installed nozzles 50 perform the proper function by removing all of the complete and immediate condensate. Batch tracing also ensures that all condensate is removed.

Inspection can be performed during operation with minimal impact on manufacturing. If the cap 60 is open and a sharp whistling sound is heard, this means that the nozzle passageway 52 is too large to allow too much vapor to pass through the exit cavity 30. Another recognition result is that the temperature of the third cavity 40 is higher than the inlet cavity 20, which means that the nozzle 50 is blocked for some reason or too narrow. In the present invention, clogged nozzles can be easily replaced.

In a preferred embodiment, the steam condensate drainer 10 is made of a non-magnetic and rigid stainless steel casting. The boundary between the cap and the main housing 12 is protected by two stainless steel gaskets and coated with graphite and a high temperature oil mixture for sealing and lubrication.

In another embodiment of the present invention, the inlet 20 and outlet 30 ends are flanged and configured to be bolted to the inlet and outlet ends of the corresponding flanged steam pipes.

While certain preferred embodiments of the present invention have been described and illustrated, it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit of the invention. Accordingly, the appended claims are intended to cover such variations, modifications, and adaptations as are within the scope of the appended claims.
