Steam trap for discharging condensate water

Abstract

The present invention relates to a steam trap for discharging condensate water, which allows condensate water supplied through a supply hole to be supplied directly to a condensate water discharge flow path formed in the inner wall surface of a guide flow path, through a filter portion immediately before the steam supplied through the supply hole reaches the condensate water discharge flow path. Here, the condensate water located in the condensate water discharge flow path is pushed out by a steam pressure to be discharged through an orifice hole, and at the same time, the condensate water blocks the orifice so as to block the steam that is to be discharged through the orifice hole, and thus, the condensate water can be rapidly discharged through the condensate water discharge flow path and the orifice hole, by being pushed out by the steam pressure, while simultaneously preventing steam loss.

Description

Steam trap for condensate drainage

[0001] The present invention relates to a steam trap, and more particularly, to a steam trap for discharging condensate, which is connected diagonally between a guide channel and an orifice hole including the edge of the bottom surface of a cylinder and connected to a condensate discharge channel having an inclined surface corresponding to the inner wall surface of the guide channel, thereby shortening the time for condensate to reach the condensate discharge channel and simultaneously causing condensate to be pressed in the direction of the orifice hole by steam, so that condensate inside a steam pipe is discharged to the outside of the steam pipe through the condensate discharge channel and the orifice hole.

[0002] In general, steam generated from production facilities, heat exchangers, steam piping facilities, etc. that use steam is transported, and condensate is usually generated inside the piping due to the temperature difference between the inside and outside, so this generated condensate must be removed.

[0003] These condensates are transported along the steam path and are called steam exhausts.

[0004] It hits the inside of the pipe, which causes water hammer, which generates noise inside the steam pipe and reduces the durability of the steam pipe, and reduces the thermal efficiency of the entire steam system in which the steam pipe is installed. Accordingly, a device called a steam trap is installed in the pipe to remove the condensate.

[0005] Here, a steam trap is a device that removes condensate generated inside a steam pipe, and is classified into a disc type, a bimetal type, a bucket type, an orifice type, etc. depending on the method of discharging the condensate. Among them, an orifice type steam trap is designed to maintain the condensate occupying the orifice hole, thereby preventing steam from leaking outside the steam trap.

[0006] Patent Document 1 (KR 10-1891578 B1) shows a conventional steam trap, and with reference thereto, it is composed of a pipe connection part forming a supply path, a discharge part installed in a direction opposite to the pipe connection part and forming a discharge path for discharging condensate, a main part installed between the pipe connection part and the discharge part and forming a main path communicating with the supply path on the inside, and a main orifice hole formed between the main path and the discharge path and an auxiliary orifice hole formed at a relatively higher position than the main orifice hole, a filter part installed between the supply path and the main path to filter out foreign substances contained in condensate supplied to the main path through the supply path, an opening / closing part installed at the top of the main path and operated to rise and fall to open and close the auxiliary orifice hole, and a guide part fixedly installed at the top of the opening / closing part to guide the rising and falling movement of the opening / closing part.

[0007] Here, when condensate and steam are supplied through the supply passage, the condensate is supplied to the main passage through the filter section, and when the level of the condensate supplied to the main passage reaches the level of the main orifice hole, the condensate is discharged at a set pressure through the main orifice hole and the discharge passage due to the pressure of the steam supplied through the supply passage, thereby removing the condensate in the steam pipe.

[0008] Meanwhile, when the condensate rises above a set level in the main passage, the opening / closing part moves upward due to the condensate and steam pressure, and at this time, the auxiliary orifice hole sealed by the opening / closing part opens, and the condensate is discharged simultaneously through the main orifice hole and the auxiliary orifice hole.

[0009] However, in the above patent document 1, the area of ​​the main channel is formed large, so that it takes a long time for the condensate in the main channel to reach a set level, and before the condensate in the main channel reaches the set level, the steam sequentially supplied to the supply channel first reaches the main orifice hole, so that the steam is discharged through the main orifice hole, and the steam discharge through the main orifice hole is continuous, so that the steam loss in the steam pipe occurs, and the steam discharge pressure is formed in the main orifice hole by the pressure of the steam discharged through the main orifice hole, so that it is very difficult to cause the condensate in the main channel to flow into the main orifice hole, and there is a concern that the condensate may flow back in the direction of the steam pipe due to the rise in the condensate level in the main channel as the condensate remains in the main channel due to the steam discharge pressure in the main orifice hole, and when the conical disc that blocks the auxiliary orifice hole is opened in the event of overflow of condensate or high pressure, the disc may not be completely sealed again due to pressure or the like after opening, or foreign substances may be caught in the conical disc. As a result, when the sealing force of the conical disc is reduced, steam loss occurs through the auxiliary orifice hole, and accordingly, the steam loss and condensate discharge effect are insufficient, which causes a problem in that the reliability of the product is reduced.

[0010] The present invention is to solve the above-described problem, and the object of the present invention is to form a supply hole at one end and a discharge hole at the other end, form a guide passage between the supply hole and the discharge hole, form a condensate discharge passage that is sunken in the inner wall surface of the guide passage toward the discharge hole, but is connected diagonally so as to include the edge of the bottom surface of the cylinder, and forms a slope corresponding to the inner wall surface of the guide passage, and has a main body that forms an orifice hole between the condensate discharge passage and the discharge hole, thereby installing a filter part in the guide passage.

[0011] The present invention provides a steam trap for condensate discharge, which supplies condensate supplied to the supply hole to a condensate discharge passage directly connected to the inner wall of a guide passage through a filter unit immediately before the steam supplied to the supply hole reaches the condensate discharge passage, and at this time, pushes the condensate located in the condensate discharge passage to be discharged through an orifice hole by steam pressure, and at the same time, causes the condensate to block the orifice, thereby preventing steam loss and allowing the condensate to be quickly discharged by the steam pressure through the condensate discharge passage and the orifice hole.

[0012] In order to achieve the above object of the present invention, a steam trap for discharging condensate according to the present invention comprises: a main body having a supply hole formed at one end for receiving steam and condensate from a condensate pipe of a steam pipe, a discharge hole formed at the other end opposite to the supply hole for discharging condensate, a guide passage formed between the supply hole and the discharge hole and extending downwardly from the supply hole to guide condensate introduced into the supply hole to move in the direction of the discharge hole, a condensate discharge passage formed in a recessed manner in the direction of the discharge hole on a wall of the guide passage, and an orifice hole formed between the condensate discharge passage and the discharge hole to guide condensate supplied to the condensate discharge passage to be discharged at a predetermined pressure toward the discharge hole; In a steam trap for discharging condensate, which is installed in the above guide channel and comprises a filter unit for filtering out foreign substances contained in condensate supplied to the condensate discharge channel through the above guide channel, the condensate discharge channel is formed in a cylindrical shape so as to be perpendicular to the center of the inlet of the orifice hole, and is characterized in that it has a shape diagonally connected to include the edge of the bottom surface of the cylinder directly connected to the inlet of the orifice hole, and the diagonally connected inclined surface is formed to correspond to the inner wall surface of the guide channel.

[0013] A steam trap for discharging condensate according to the present invention comprises: a main body having a supply hole formed at one end for receiving steam and condensate from a condensate pipe of a steam pipe, a discharge hole formed at the other end opposite to the supply hole for discharging condensate, a guide channel formed to extend downwardly from the supply hole between the supply hole and the discharge hole to guide condensate introduced into the supply hole to move in the direction of the discharge hole, a condensate discharge channel formed to be sunken in the inner wall surface of the guide channel in the direction of the discharge hole to allow condensate in the guide channel to move in the direction of the discharge hole, and an orifice hole formed between the condensate discharge channel and the discharge hole to guide condensate supplied to the condensate discharge channel to be discharged at a predetermined pressure toward the discharge hole; It is composed of a filter unit installed in the above guide channel and filtering out foreign substances contained in condensate supplied to the condensate discharge channel through the above guide channel, and the orifice hole of the main body is formed in a multi-stage structure of four recesses so that the diameter thereof expands as it goes from the condensate discharge channel toward the discharge hole, and the lengths thereof are formed to have different lengths, so that the condensate supplied to the condensate discharge channel is guided to be discharged in the direction of the discharge hole.

[0014] In the steam trap for discharging condensate according to the present invention, the main body is characterized in that it has a bottom end of the guide channel that opens and forms a spiral on the inner surface thereof, the filter part is a hollow shape that is opened at the top and bottom, is inserted and coupled into the guide channel to form a plurality of condensate passage holes spaced at a set interval on the outer surface, and allows condensate to flow in through the top end, while discharging condensate purified of foreign substances through the condensate passage holes into the condensate discharge channel; and a closing lid that is connected to the bottom end of the guide channel in a spiral manner and closes the bottom end of the guide channel so that the filter is positioned within the guide channel.

[0015] In the steam trap for condensate discharge according to the present invention, the condensate discharge path of the main body is characterized in that the distance from the center of the inclined surface to the bottom surface of the cylinder connected to the orifice hole is formed to be 0.9 mm to 2.2 mm long.

[0016] In the steam trap for condensate discharge according to the present invention, the filter part is characterized in that the upper height of the filter, which is installed to be inclined downward to correspond to the shape of the guide passage, is formed relatively higher than the height of the condensate discharge passage, so that the condensate flowing into the supply hole of the main body is supplied to the condensate discharge passage via the filter.

[0017] In the steam trap for condensate discharge according to the present invention, the main body is characterized in that the bottom surface of the condensate discharge passage is connected in a right-angled structure at the center of the inlet of the orifice hole and is formed in a recessed shape of an inverted right triangle cylinder toward the orifice hole from the inclined surface so that steam moving horizontally in the direction of the condensate discharge passage through the supply hole strikes condensate located in the condensate discharge passage toward the orifice hole.

[0027] Hereinafter, embodiments of the present invention will be described in more detail with reference to the attached drawings.

[0028] [Example 1]

[0029] Referring to FIGS. 1 to 7, the main body (100) forms a supply hole (101) at one end for receiving steam and condensate from a condensate pipe (P1) of a steam pipe (P), forms a discharge hole (102) for discharging condensate at the other end opposite to the supply hole (101), forms a guide channel (103) between the supply hole (101) and the discharge hole (102) and extends downwardly from the supply hole (101) to guide the condensate flowing into the supply hole (101) to move toward the discharge hole (102), forms a condensate discharge channel (104) recessed in the direction of the discharge hole (102) on the wall of the guide channel, and forms the condensate discharge channel (104) between the condensate discharge channel (104) and the discharge hole (102) so that the condensate supplied to the condensate discharge channel (104) flows toward the discharge hole (102). An orifice hole (105) is formed to guide the discharge by pressure.

[0030] The above main body (100) receives condensate and steam flowing along the condensate pipe (P1) connected to the steam pipe (P) through the supply hole (101).

[0031] The above supply hole (101) receives steam and condensate and guides the condensate to be supplied to the guide path (103).

[0032] The above discharge hole (102) is installed at the opposite end to the supply hole (101) to guide the condensate to be discharged to the outside.

[0033] The above guide path (103) guides the condensate introduced through the supply hole (101) to be supplied to the condensate discharge path (104) via the filter unit (200).

[0034] The above guide path (103) allows the filter unit (200) to be installed inside it.

[0035] The above guide path (103) is directly connected to the condensate discharge path (104), allowing condensate to be supplied to the condensate discharge path (104).

[0036] The above main body (100) opens the lower end of the guide path (103) and forms a spiral on its inner surface.

[0037] The above guide passage (103) allows the filter unit (200) to be inserted through the bottom, and the closing cap (202) of the filter unit (200) is fastened in a spiral manner so that the bottom is closed.

[0038] The above condensate discharge path (104) is formed directly connected to the inner wall surface of the guide path (103) to correspond to the height of the orifice hole (105), and allows condensate to be discharged in the direction of the orifice hole (105).

[0039] The above condensate discharge path (104) is formed over a short distance so that the condensate within the guide path (103) is quickly discharged toward the orifice hole (105).

[0040] The above condensate discharge path (104) is formed in a cylindrical shape so as to be perpendicular to the center of the inlet of the orifice hole (105), and is diagonally connected to include the edge of the cylindrical bottom surface (104a) directly connected to the inlet of the orifice hole (105), and the diagonally connected inclined surface (104b) is formed so as to correspond to the inner wall surface of the guide path (103).

[0041] The inclined surface (104b) of the above condensate discharge path (104) is formed to be inclined at a 45 degree angle to correspond to the inner wall surface of the above guide path (103).

[0042] The above condensate discharge path (104) is directly connected to the cylindrical guide path (103) in a short-distance diagonal shape with a radius equal to the distance from the center of the inlet of the orifice hole (105) based on the point where the lower edge of the bottom surface of the cylinder (104a) connects to the inner wall surface of the guide path (103) inclined at a 45-degree angle.

[0043] The above condensate discharge path (104) is formed so that the bottom surface of the cylinder (104a) is directly connected to the inlet of the orifice hole (105), and the inclined surface (104b) corresponds to the inner wall surface of the guide path (103) that is inclined at a 45 degree angle.

[0044]

[0045] The above condensate discharge channel (104) is directly connected to the inner wall surface of the above guide channel (103) in a diagonal shape and is formed in a cylindrical shape with a cross-section that forms a right triangle in the reverse direction, thereby supplying condensate.

[0046] The above cylindrical bottom surface (104a) is blocked by condensate, and causes a collision of steam, so that the condensate is discharged toward the orifice hole (105) by the pressure of the steam.

[0047] The above-mentioned inclined surface (104b) is connected diagonally so as to be directly connected to the inner wall surface of the guide channel (103), thereby allowing condensate to flow into the condensate discharge channel (104).

[0048] The condensate discharge path (104) of the above main body (100) is formed by recessing the distance from the center of the inclined surface (104b) to the cylindrical bottom surface (104a) connected to the orifice hole (105) to a length of 0.9 mm to 2.2 mm.

[0049] The above condensate discharge path (104) was manufactured as a short-distance shape having a cylindrical shape of an inverted right triangle by collecting data on lengths of 0.9 mm to 2.2 mm through repeated experiments, and accordingly, the condensate has the effect of arriving earlier than steam, thereby providing an effect suitable for preventing steam loss due to steam discharge due to the phenomenon of the entrance of the orifice hole (105) being blocked.

[0050] In the case where the main body is 1 / 2 inch, the diameter of the cylindrical bottom surface (104a) and the length of the upper end of the condensate discharge channel (104) are each formed to have the same size of 1.8 mm. In the case where the main body is 3 / 4 inch, the diameter of the cylindrical bottom surface (104a) and the length of the upper end of the condensate discharge channel (104) are each formed to have the same size of 3.1 mm. In the case where the main body is 1 inch, the diameter of the cylindrical bottom surface (104a) and the length of the upper end of the condensate discharge channel (104) are each formed to have the same size of 4.4 mm.

[0051] Data on the length of the cylindrical bottom surface (104a) and the upper part of the above condensate discharge path (104) are as shown in Table 1 below.

[0052] Classification 1 / 2 inch (15A) 3 / 4 inch (20A) 1 inch (25A) Note Diameter of the bottom of the cylinder (D) mm 1.8 3.14.4 D = L Length of the top of the condensate discharge path (L) mm 1.8 3.14.4 Length of the bottom of the cylinder to the center of the inclined surface (L1) mm 0.9 1.5 5 2.2 L1 = L / 2

[0053] The condensate discharge channel (104) is formed so that the length from the center of the cylindrical bottom surface (104a) to the slanted surface (104b) is less than 0.9 mm, based on the center of the slanted surface (104b), and when the cylindrical bottom surface (104a) is formed close to the slanted surface direction, the cylindrical bottom surface (104a) enters deeper in the inner wall surface of the guide channel (103), so that a step projection proportional to the exposure distance of the cylindrical bottom surface (104a) is formed on the inner wall surface of the guide channel (103), so that the condensate is blocked by the step projection, and accordingly, the supply of condensate is not smooth, and the time for condensate to be supplied to the condensate discharge channel (104) is delayed. The condensate discharge channel (104) is formed so that the length from the center of the cylindrical bottom surface (104a) to the slanted surface (104b) is less than 0.9 mm, based on the center of the slanted surface (104b), and when the cylindrical bottom surface (104a) is formed close to the slanted surface direction, the cylindrical bottom surface (104a) enters deeper in the inner wall surface of the guide channel (103), so that the condensate is blocked by the step projection, and accordingly, the supply of condensate is not smooth, and the time for condensate to be supplied to the condensate discharge channel (104) is delayed. In the case where the length to the inclined surface (104b) is formed to exceed 2.2 mm, the cylindrical bottom surface (104a) is spaced from the inclined surface (104b) to exceed 2.2 mm, and the depth of the depression from the inclined surface (104b) to the cylindrical bottom surface (104a) gradually deepens in proportion to the distance of the cylindrical bottom surface (104a), thereby delaying the time for condensate to reach the cylindrical bottom surface (104a). Accordingly, in a state where the cylindrical bottom surface (104a) is not sealed by the condensate, steam is discharged through the orifice hole (105), resulting in steam loss.

[0054] The above body (100) is formed in a cylindrical shape of an inverted right triangle, with the condensate discharge path (104) diagonally connected to the inner wall surface of the guide path (103), so that steam moving horizontally in the direction of the condensate discharge path (104) through the supply hole (101) strikes the condensate located in the condensate discharge path (104) toward the orifice hole (105), and the bottom surface of the cylinder (104a) is formed recessed to form a right-angled groove in the direction of the orifice (105) at a right angle to the center of the inlet of the orifice hole (105).

[0055] The above condensate discharge path (104) is formed in a right-angled structure so as to be perpendicular to the steam supply direction that flows in through the supply hole (101) and moves horizontally in the direction of the above condensate discharge path (104), so that steam collides with the cylindrical bottom surface (104a).

[0056] The height of the above condensate discharge path (104) is formed at a position relatively lower than the height of the upper part of the filter (201) of the above filter unit (200), thereby preventing the condensate flowing into the supply hole (101) from passing directly through.

[0057] The above orifice hole (105) allows the condensate to be sprayed at a set pressure toward the discharge hole (102).

[0058] The above orifice hole (105) sprays and discharges condensate at different pressures depending on its diameter and length.

[0059] The filter unit (200) is installed in the guide channel (103) to filter out foreign substances contained in the condensate supplied to the condensate discharge channel (104) through the guide channel (103).

[0060] The above filter unit (200) catches foreign substances contained in the condensate supplied into the guide channel (103) on the inside, and discharges the condensate purified of foreign substances toward the inner wall surface of the guide channel (103), so that the condensate is supplied to the condensate discharge channel (104).

[0061] The above filter unit (200) is a hollow shape with the upper and lower ends open, and is inserted and coupled within the guide channel (103) to form a plurality of condensate passage holes (201a) spaced at a set interval on the outer surface, and further includes a filter (201) that allows condensate to flow in through the upper end and discharges condensate purified of foreign substances through the condensate passage holes (201a) to the condensate discharge channel (104), and a closing cap (202) that is connected to the lower end of the guide channel (103) in a spiral manner and closes the lower end of the guide channel (103) so that the filter (201) is positioned within the guide channel (103).

[0062] The diameter of the filter (201) is formed relatively smaller than the diameter of the guide channel (103), so that the condensed water purified of foreign substances is discharged into the space between the filter (201) and the inner wall surface of the guide channel (103).

[0063] It is preferable that the above filter (201) be formed in a cylindrical shape so that foreign substances are caught inside.

[0064] The above filter (201) is adhered to the inner wall surface to further form a mesh filter net (201a-1) that filters out fine foreign substances contained in the condensate discharged through the condensate passage hole (201a).

[0065] The above mesh filter net (201a-1) is an integral part connected to the filter (201), and is formed of a fine stainless steel wire mesh to filter out fine foreign substances contained in the condensate.

[0066] The above mesh filter net (201a-1) is formed with a thickness of 0.114 mm, and the spacing between the wire meshes is formed with a spacing of 0.14 mm X 0.14 mm.

[0067] The above closing lid (202) seals the bottom of the guide channel (103) to prevent condensate from leaking through the bottom of the guide channel (103).

[0068] It is preferable that the above closing lid (202) be formed with a sealing packing (202a) on the outer edge and be connected in a spiral manner to the lower end of the guide channel (103).

[0069] The above-mentioned sealing packing (202a) is compressed between the lower edge of the guide channel (103) and the closing lid (202), thereby sealing the space between the closing lid (202) and the lower edge of the guide channel (103).

[0070] The filter section (200) is installed with a downward slope corresponding to the shape of the guide channel (103) so that the upper height of the filter (201) is formed relatively higher than the height of the condensate discharge channel (104), so that the condensate flowing into the supply hole (101) of the main body (100) is supplied to the condensate discharge channel (104) via the filter (201).

[0071] The above filter (201) allows the condensate flowing into the supply hole (101) to pass through, filters out foreign substances contained in the condensate, and then discharges the condensate purified of foreign substances through the condensate discharge path (104).

[0074] [Description of the first embodiment]

[0075] The steam trap for condensate discharge according to the first embodiment of the present invention configured as described above is used as follows.

[0076] Below, an example is described in which a condensate drain pipe (P1) for draining condensate is formed in a steam pipe (P).

[0077] First, the supply hole (101) of the main body (100) is connected to the condensate drain pipe (P1) connected to the steam pipe (P), so that the main body (100) is fastened to the condensate drain pipe (P1), and in that state, the filter unit (200) is introduced into the guide passage (103) through the lower end of the guide passage (103).

[0078] At this time, the filter (201) of the filter unit (200) is inserted into the guide channel (103), and its upper end is in close contact with the inner upper end of the guide channel (103), so that the filter (201) is positioned at a relatively higher position than the condensate discharge channel (104).

[0079] Then, by inserting the closing cap (202) of the filter unit (200) into the lower part of the guide channel (103), and fastening the closing cap (202) in a spiral manner to the inner surface of the lower part of the guide channel (103), the lower part of the guide channel (103) is sealed.

[0080] At this time, a sealing packing (202a) is provided between the closing lid (202) and the lower edge of the guide channel (103), and is pressed tightly against the lower edge of the guide channel (103) by the closing lid (202), so that the space between the closing lid (202) and the lower edge of the guide channel (103) is sealed, and accordingly, leakage of condensate through the gap between the closing lid (202) and the lower edge of the guide channel (103) is prevented.

[0081] Thereafter, when steam is supplied through the steam pipe (P), the steam moves through the steam pipe (P) and heats the steam pipe (P) through heat exchange, and at this time, the heated steam pipe (P) undergoes heat exchange with the outside air around the steam pipe (P), and condensation is generated in the form of water droplets on the inner wall surface of the steam pipe (P).

[0082] And, the condensate generated within the steam pipe (P) falls and moves through the condensate drain pipe (P1), and at this time, condensate and steam are supplied to the condensate drain pipe (P1).

[0083] Thereafter, when condensate reaches the supply hole (101) of the main body (100) through the condensate drain pipe (P1) due to steam pressure, the condensate is supplied to the guide channel (103) connected to the supply hole (101), and at this time, the condensate flows into the filter (201) through the upper part of the filter (201) in the guide channel (103).

[0084] Here, the condensate that has flowed into the inside of the filter (201) through the opened top of the filter (201) is discharged into the space between the guide channel (103) and the filter (201) through the condensate passage hole (201a) of the filter (201), and then supplied to the condensate discharge channel (104) that is directly connected to the guide channel (103).

[0085] That is, the above guide channel (103) supplies condensate into the condensate discharge channel (104) through the inclined surface (104b), while causing the bottom surface of the cylinder (104a) to be blocked by the condensate.

[0086] At this time, a stainless steel mesh filter net (201a-1) is installed on the inner wall surface of the filter (201), and by discharging the condensate through the mesh filter net (201a-1) toward the condensate passage hole (201a), fine foreign substances contained in the condensate are filtered out.

[0087] At this time, the condensate is discharged through the condensate passage hole (201a) of the filter (201), and foreign substances contained in the condensate are filtered out and remain inside the filter (201).

[0088] And, the condensate discharge path (104) is formed in a cylindrical shape recessed into an inverted right triangle shape so as to be directly connected to the inner wall surface of the guide path (103), so that the condensate that has passed through the filter (201) is directly supplied, so that the condensate that is pushed in by the steam pressure through the supply hole (101) first reaches the condensate discharge path (104) just before the steam reaches it.

[0089] At this time, the condensate flowing in through the inclined surface (104b) of the condensate discharge channel (104) reaches the bottom surface (104a) of the cylinder within the condensate discharge channel (104), thereby sealing and blocking the orifice hole (105) connected to the bottom surface (104a) of the cylinder.

[0090] In addition, the condensate discharge path (104) is formed relatively lower than the upper height of the filter (201), so that condensate purified of foreign substances is supplied while passing through the filter (201).

[0091] Thereafter, the condensate that has reached the condensate discharge path (104) is forced into the orifice hole (105) by the steam pressure that collides with the bottom surface (104a) of the cylinder through the inclined surface (104b) of the condensate discharge path (104) via the supply hole (101), and at this time, is discharged through the orifice hole (105) to the discharge hole (102).

[0092] Here, the condensate discharge channel (104) is formed to have a length of 0.9 mm to 2.2 mm, so that the condensate supplied to the condensate discharge channel (104) is directly supplied to the orifice hole (105) by steam pressure, thereby preventing the condensate from remaining in the condensate discharge channel (104).

[0093] In particular, the cylindrical bottom surface (104a) of the condensate discharge passage (104) has a structure perpendicular to the center of the inlet of the orifice hole (105), and is formed to be directly connected to the inlet of the orifice hole (105) and is blocked by condensate, but when steam collides with the cylindrical bottom surface (104a) of the condensate discharge passage (104) connected to the orifice hole (105), the condensate is pressed toward the orifice hole (105).

[0094] That is, the condensate discharge path (104) is formed as a short-distance structure so as to be directly connected to the 45-degree inclined inner wall surface of the guide path (103), so that as soon as the condensate reaches it, it is pushed by the steam pressure and is guided to be directly supplied to the orifice hole (105), thereby preventing the condensate from remaining in the condensate discharge path (104).

[0095] Thereafter, the condensate flowing into the orifice hole (105) spreads radially toward the discharge hole (102) and is discharged to the outside through the discharge hole (102).

[0096] That is, the diameter of the orifice hole (105) is gradually expanded so that the condensate is gradually expanded and sprayed in the direction of the discharge hole (102), thereby spraying and discharging the condensate through the discharge hole (102).

[0097] And, while continuously supplying condensate and steam through the supply hole (101) as described above, the condensate that has reached the condensate discharge path (104) is forcibly injected into the orifice hole (105) through steam pressure, thereby discharging the condensate generated within the steam pipe (P) to the outside, while allowing steam to remain within the steam pipe (P).

[0099] [Example 2]

[0100] Referring to Figures 1 to 6, the main body (100) is

[0101] The main body (100) forms a supply hole (101) at one end for receiving steam and condensate from a condensate pipe (P1) of a steam pipe (P), and forms a discharge hole (102) for discharging condensate at the other end opposite to the supply hole (101), and forms a guide channel (103) between the supply hole (101) and the discharge hole (102) and extends downwardly from the supply hole (101) to guide the condensate flowing into the supply hole (101) to move toward the discharge hole (102), and forms a condensate discharge channel (104) that is recessed in the inner wall surface of the guide channel (103) toward the discharge hole (102) and allows the condensate in the guide channel (103) to move toward the discharge hole (102), and forms the condensate discharge channel (104) between the condensate discharge channel (104) and the discharge hole (102). An orifice hole (105) is formed to guide the condensate supplied to the condensate discharge path (104) to be discharged at a set pressure toward the discharge hole (102).

[0102] The above main body (100) receives condensate and steam flowing along the condensate pipe (P1) through the supply hole (101).

[0103] The above supply hole (101) receives steam and condensate and guides the condensate to be supplied to the guide path (103).

[0104] The above discharge hole (102) is installed at the opposite end to the supply hole (101) to guide the condensate to be discharged to the outside.

[0105] The above guide path (103) guides the condensate introduced through the supply hole (101) to be supplied to the condensate discharge path (104) via the filter unit (200).

[0106] The above guide path (103) allows the filter unit (200) to be installed inside it.

[0107] The above guide path (103) is directly connected to the condensate discharge path (104), allowing condensate to be supplied to the condensate discharge path (104).

[0108] The above main body (100) opens the lower end of the guide path (103) and forms a spiral on its inner surface.

[0109] The above guide passage (103) allows the filter unit (200) to be inserted through the bottom, and the closing cap (202) of the filter unit (200) is fastened in a spiral manner so that the bottom is closed.

[0110] The above condensate discharge path (104) is formed on the inner wall surface of the guide path (103) to correspond to the height of the orifice hole (105), so that condensate is discharged in the direction of the orifice hole (105).

[0111] It is preferable that the above condensate discharge path (104) be formed over a short distance so that the condensate within the guide path (103) is quickly discharged toward the orifice hole (105).

[0112] The above body (100) forms the condensate discharge path (104) in a recessed structure perpendicular to the center line of the orifice hole (105) so that steam moving horizontally in the direction of the condensate discharge path (104) through the supply hole (101) strikes the condensate located in the condensate discharge path (104) toward the orifice hole (105).

[0113] The above condensate discharge path (104) is formed in a right-angled structure so as to be perpendicular to the steam supply direction that flows in through the supply hole (101) and moves horizontally in the direction of the condensate discharge path (104), thereby causing the steam to collide.

[0114] The height of the above condensate discharge path (104) is formed at a position relatively lower than the height of the upper part of the filter (201) of the above filter unit (200), thereby preventing the condensate flowing into the supply hole (101) from passing directly through.

[0115] The orifice hole (105) of the main body (100) is formed in a four-stage structure so that its diameter expands as it goes from the condensate discharge path (104) toward the discharge hole (102), and its length is formed to have different lengths, thereby guiding the condensate supplied to the condensate discharge path (104) to be discharged toward the discharge hole (102).

[0116] The above orifice hole (105) allows the condensate to be sprayed at a set pressure toward the discharge hole (102).

[0117] The above orifice hole (105) sprays and discharges condensate at different pressures depending on its diameter and length.

[0118] The above orifice hole (105) is preferably formed with a first hole (105a) that is formed to have a length of 1 mm and a diameter of 0.6 mm to 0.8 mm and is connected to the condensate discharge path (104), a second hole (105b) that is formed to have a length of 3.4 mm and a diameter of 1.3 mm and is connected to the first hole (105a), a third hole (105c) that is formed to have a length of 12.6 mm and a diameter of 4.4 mm and is connected to the second hole (105b), and a fourth hole (105d) that is formed to have a length of 8.1 mm and a diameter of 8 mm and is connected between the third hole (105c) and the discharge hole (102).

[0119] It is preferable that the diameter of the first hole (105a) be formed to be 0.6 mm to 0.8 mm depending on the diameter of the supply hole (101) and discharge hole (102) of the main body (100).

[0120] As described in Table 1, when the body (100) is 1 / 2 inch, the diameter of the first hole (105a) is formed to be 0.6 mm, when the body (100) is 3 / 4 inch, the diameter of the first hole (105a) is formed to be 0.7 mm, and when the body (100) is 1 inch, the diameter of the first hole (105a) is formed to be 0.8 mm. However, it is preferable that the length of the first hole (105a), the lengths and diameters of the second hole (105b), the third hole (105c), and the fourth hole (105d) be formed to be the same.

[0121] The lengths of the second hole (105b), the third hole (105c), and the fourth hole (105d) of the above orifice hole (105) include the lengths of the expansion slope (105') that gradually expands the space between the second hole (105b) and the third hole (105c), the third hole (105c) and the fourth hole (105d), and the fourth hole (105d) and the discharge hole (102).

[0122] As a result of the experiment under the above conditions, when 4 bar of steam pressure was supplied into the main body (100), 0.5% occurred when the steam loss range was 1 / 2 inch, 2.1% occurred when it was 3 / 4 inch, and 1.7% occurred when it was 1 inch, thereby obtaining the desired result.

[0124] In addition, when 20 bar of steam pressure is supplied into the main body (100), as shown in Table 2, 5.5% occurs when the steam loss range is 1 / 2 inch, 11.8% occurs when it is 3 / 4 inch, and 9.8% occurs when it is 1 inch, thereby obtaining the desired result.

[0126] The second hole (105b) and the third hole (105c) of the above orifice hole (105), the third hole (105c) and the fourth hole (105d), and the fourth hole (105d) and the discharge hole (102) are connected by an expansion slope (105') that gradually expands the space between them. The expansion slope (105') is formed to be inclined at a predetermined angle, thereby guiding the expansion and spraying from the second hole (105b) toward the third hole (105c) and from the third hole (105c) toward the fourth hole (105d).

[0127] The filter unit (200) is installed in the guide channel (103) to filter out foreign substances contained in the condensate supplied to the condensate discharge channel (104) through the guide channel (103).

[0128] The above filter unit (200) catches foreign substances contained in the condensate supplied into the guide channel (103) on the inside, and discharges the condensate purified of foreign substances toward the inner wall surface of the guide channel (103), so that the condensate is supplied to the condensate discharge channel (104).

[0129] The above filter unit (200) is a hollow shape with the upper and lower ends open, and is inserted and coupled within the guide channel (103) to form a plurality of condensate passage holes (201a) spaced at a set interval on the outer surface, and further includes a filter (201) that allows condensate to flow in through the upper end and discharges condensate purified of foreign substances through the condensate passage holes (201a) to the condensate discharge channel (104), and a closing cap (202) that is connected to the lower end of the guide channel (103) in a spiral manner and closes the lower end of the guide channel (103) so that the filter (201) is positioned within the guide channel (103).

[0130] The diameter of the filter (201) is formed relatively smaller than the diameter of the guide channel (103), so that the condensed water purified of foreign substances is discharged into the space between the filter (201) and the inner wall surface of the guide channel (103).

[0131] It is preferable that the above filter (201) be formed in a cylindrical shape so that foreign substances are caught inside.

[0132] The above filter (201) is adhered to the inner wall surface to further form a mesh filter net (201a-1) that filters out fine foreign substances contained in the condensate discharged through the condensate passage hole (201a).

[0133] The above mesh filter net (201a-1) is an integral part connected to the filter (201), and is formed of a fine wire mesh made of stainless steel, and filters out fine foreign substances contained in condensate.

[0134] The above mesh filter net (201a-1) is formed with a thickness of 0.114 mm, and the spacing between the wire meshes is formed with a spacing of 0.14 mm X 0.14 mm.

[0135] The above closing lid (202) seals the bottom of the guide channel (103) to prevent condensate from leaking through the bottom of the guide channel (103).

[0136] It is preferable that the above closing lid (202) be formed with a sealing packing (202a) on the outer edge and be connected in a spiral manner to the lower end of the guide channel (103).

[0137] The above-mentioned sealing packing (202a) is compressed between the lower edge of the guide channel (103) and the closing lid (202), thereby sealing the space between the closing lid (202) and the lower edge of the guide channel (103).

[0138] The filter section (200) is installed with a downward slope corresponding to the shape of the guide channel (103) so that the upper height of the filter (201) is formed relatively higher than the height of the condensate discharge channel (104), so that the condensate flowing into the supply hole (101) of the main body (100) is supplied to the condensate discharge channel (104) via the filter (201).

[0139] The above filter (201) allows the condensate flowing into the supply hole (101) to pass through, filters out foreign substances contained in the condensate, and then discharges the condensate purified of foreign substances through the condensate discharge path (104).

[0142] [Description of the second embodiment]

[0143] The steam trap for condensate discharge according to the second embodiment of the present invention configured as described above is used as follows.

[0144] Below, an example is described in which a condensate drain pipe (P1) for draining condensate is formed in a steam pipe (P).

[0145] First, the supply hole (101) of the main body (100) is connected to the condensate drain pipe (P1) connected to the steam pipe (P), so that the main body (100) is fastened to the condensate drain pipe (P1), and in that state, the filter unit (200) is introduced into the guide passage (103) through the lower end of the guide passage (103).

[0146] At this time, the filter (201) of the filter unit (200) is inserted into the guide channel (103), and its upper end is in close contact with the inner upper end of the guide channel (103), so that the filter (201) is positioned at a relatively higher position than the condensate discharge channel (104).

[0147] Then, by inserting the closing cap (202) of the filter unit (200) into the lower part of the guide channel (103), and fastening the closing cap (202) in a spiral manner to the inner surface of the lower part of the guide channel (103), the lower part of the guide channel (103) is sealed.

[0148] At this time, a sealing packing (202a) is provided between the closing lid (202) and the lower edge of the guide channel (103), and is pressed tightly against the lower edge of the guide channel (103) by the closing lid (202), so that the space between the closing lid (202) and the lower edge of the guide channel (103) is sealed, and accordingly, leakage of condensate through the gap between the closing lid (202) and the lower edge of the guide channel (103) is prevented.

[0149] Thereafter, when steam is supplied through the steam pipe (P), the steam moves through the steam pipe (P) and heats the steam pipe (P) through heat exchange, and at this time, the heated steam pipe (P) undergoes heat exchange with the outside air around the steam pipe (P), and condensation is generated in the form of water droplets on the inner wall surface of the steam pipe (P).

[0150] And, the condensate generated within the steam pipe (P) falls and moves through the condensate drain pipe (P1), and at this time, condensate and steam are supplied to the condensate drain pipe (P1).

[0151] Thereafter, when condensate reaches the supply hole (101) of the main body (100) through the condensate drain pipe (P1) due to steam pressure, the condensate is supplied to the guide channel (103) connected to the supply hole (101), and at this time, the condensate flows into the filter (201) through the upper part of the filter (201) in the guide channel (103).

[0152] Here, the condensate that has flowed into the inside of the filter (201) through the opened top of the filter (201) is discharged into the space between the guide channel (103) and the filter (201) through the condensate passage hole (201a) of the filter (201), and then supplied to the condensate discharge channel (104) that is directly connected to the guide channel (103).

[0153] At this time, a stainless steel mesh filter net (201a-1) is installed on the inner wall surface of the filter (201), and by discharging the condensate through the mesh filter net (201a-1) toward the condensate passage hole (201a), fine foreign substances contained in the condensate are filtered out.

[0154] At this time, the condensate is discharged through the condensate passage hole (201a) of the filter (201), and foreign substances contained in the condensate are filtered out and remain inside the filter (201).

[0155] And, the condensate discharge path (104) is formed by being sunken into the inner wall surface of the guide path (103), and after receiving the condensate that has passed through the filter (201), steam is supplied, and the condensate is forced by the steam pressure and injected into the orifice hole (105), and at this time, it is discharged through the orifice hole (105) to the discharge hole (102).

[0156] In particular, the condensate discharge path (104) is formed relatively lower than the upper height of the filter (201), so that condensate purified of foreign substances is supplied while passing through the filter (201).

[0157] Here, the condensate supplied to the condensate discharge channel (104) is continuously supplied to the orifice hole (105) by steam pressure, thereby preventing the condensate from remaining in the condensate discharge channel (104).

[0158] In particular, the condensate discharge passage (104) is formed in a sunken state to have a right-angled structure at the center of the inlet of the orifice hole (105) so as to receive the condensate, so that the steam collides with the wall of the condensate discharge passage (104) connected to the orifice hole (105) and pressurizes the condensate toward the orifice hole (105).

[0159] That is, as soon as the condensate reaches the condensate discharge path (104), it is guided so that the condensate is supplied directly to the orifice hole (105) by the steam pressure.

[0160] Thereafter, the condensate flowing into the orifice hole (105) is discharged to the discharge hole (102) through the first hole (105a), second hole (105b), third hole (105c), and fourth hole (105d).

[0161] Here, the length of the first hole (105a) is 1 mm, but the diameter is formed to be 0.6 mm to 0.8 mm, so that condensate is quickly discharged to the second hole (105b).

[0162] In addition, the second hole (105b) that receives condensate from the first hole (105a) is formed to have a length of 3.4 mm and a diameter of 1.3 mm, thereby delaying the movement of condensate relatively compared to the first hole (105a) and guiding the condensate to be sprayed in an expanded manner relatively compared to the first hole (105a).

[0163] In addition, the third hole (105c) that receives condensate from the second hole (105b) is formed to have a length of 12.6 mm and a diameter of 4.4 mm, thereby delaying the movement of condensate relatively compared to the second hole (105b) and guiding the condensate to be sprayed in a relatively more expanded manner compared to the second hole (105b).

[0164] In addition, the fourth hole (105d) that receives condensate from the third hole (105c) is formed to have a length of 8.1 mm and a diameter of 8 mm, so that the condensate moves relatively quickly compared to the third hole (105c), while guiding the condensate to be sprayed in a relatively more expanded manner compared to the third hole (150c).

[0165] That is, the diameters of the first, second, third, and fourth holes (105a, 105b, 105c, 105d) of the orifice hole (105) are gradually expanded, but their lengths are formed differently, so that the condensate is gradually expanded and sprayed in the direction of the discharge hole (102), thereby discharging the condensate through the discharge hole (102).

[0166] At this time, depending on the diameter and length of the first, second, third and fourth holes (105a, 105b, 105c, 105d), the injection pressure and injection speed of the condensate injected through the orifice hole (105) are changed, and at this time, most preferably, by manufacturing it with the above length and diameter, the injection pressure and injection speed of the condensate are improved, thereby preventing temperature and pressure changes in the steam pipe (P) due to steam loss and simultaneously quickly discharging the condensate.

[0167] For example, by supplying 4 bar of steam pressure to each of the 1 / 2 inch body (100), 3 / 4 inch body (100), and 1 inch body (100), the desired result of generating steam loss rates of 0.5%, 2.1%, and 1.7%, respectively, when pushing out condensate was obtained.

[0168] And, when supplying steam pressure of 20 bar to push out condensate, the desired results of generating steam loss rates of 5.5%, 11.8%, and 9.8%, respectively, were obtained.

[0169] In particular, the second, third, and fourth holes (105b, 105c, 105d) of the orifice hole (105) are connected by an expansion slope (105') between them, so that the condensate is guided to the expansion slope (105') while passing through each of the second, third, and fourth holes (105b, 105c, 105d) and is sprayed radially to expand.

[0170] And, while continuously supplying condensate and steam through the supply hole (101) as described above, the condensate that has reached the condensate discharge path (104) is forcibly injected into the orifice hole (105) through steam pressure, thereby discharging the condensate generated within the steam pipe (P) to the outside, while allowing steam to remain within the steam pipe (P).

[0171] As described above, the structure in which the condensate discharge path (104) is formed to be directly connected to the inner wall of the guide path (103), so that the condensate reaches the condensate discharge path (104) before the steam introduced through the supply hole (101) reaches the condensate discharge path (104) is formed by forming a short-distance condensate discharge path (104) directly connected to the inner wall of the guide path (103), so that the condensate supplied to the guide path (103) is directly supplied to the condensate discharge path (104), and the condensate is located in the condensate discharge path (104) just before the steam reaches the condensate discharge path (104), and the condensate located in the condensate discharge path (104) is pushed out by the steam pressure, so that the condensate is discharged to the discharge hole (102) through the orifice hole (105). Thus, condensate can be easily discharged.

[0172] The steam trap for condensate discharge according to the present invention described above is not limited to the above-described embodiment, and has the technical spirit to the extent that anyone with ordinary knowledge in the field to which the present invention pertains can make various modifications and implement the present invention without departing from the gist of the present invention claimed in the claims below.
