Definitions
- the present invention relates to an orifice type disk steam trap, and more particularly, to combine the advantages of the conventional disk type and the orifice type to minimize the discharge of steam and facilitate the discharge of condensate, maintenance of the steam trap
- An orifice type disk steam trap that can be easily used for a long time.
- Pipes that transfer steam in production facilities, heat exchangers, and steam piping facilities that use steam (steam) have a large temperature difference between the inside and the outside of the transfer pipe due to high temperature and high pressure steam. It is very common to produce condensation water or condensed water in the conveying pipe due to the temperature difference.
- the condensed water may cause a water hammer that hits the steam transport pipe and generates a lot of noise in the steam transport pipe.
- a steam keeper or steam trap can be installed on the steam pipe to remove condensate.
- the steam trap automatically discharges the condensed water from the steam transport pipe to the outside of the steam transport pipe.
- Ball trap method, disk method, bimetal method, bucket method, orifice method and various technologies are introduced and used.
- the ball float steam trap is a method of automatically discharging condensate to the outside of the steam transport pipe by using the density difference between steam and condensate, and is not affected by sudden fluctuations in pressure and flow rate, but damages caused by freezing are caused. There is.
- the bimetallic steam trap bimetal is formed by attaching two kinds of metals having different thermal expansion rates, and bends due to temperature change.
- Bucket type steam trap is a method in which the bucket floats and closes the drain valve (closes) .
- the drain bucket sinks and the drain valve directly connected to the bucket is opened by the steam pressure. It operates by discharging condensate in the bucket to the outside through the drain.
- the orifice type steam trap minimizes leakage of steam, does not need to be operated, and has a large economic effect due to advantages such as a small heating area and improved heat transfer rate to the heating element.
- the nozzle can be cleaned and replaced only by disassembling the entire steam trap when the nozzle hole provided therein is in contact with foreign matter or damage. There is a problem that is not easy.
- the disk type steam trap operates by discharging the condensate to the outside as the disc is lifted because the internal temperature of the steam trap decreases when the condensate accumulates in the steam trap.
- a typical disk type steam trap has an inlet (2) for entering condensate into the body (1) and an outlet (3) to the outside as shown in FIG. 1, and a passage (4) is formed between the inlet and the outlet.
- a disk 5 is provided to open and close this passage, and a transformer 6 is provided in which the disk can be moved up and down.
- the disk type steam trap having such a configuration flows condensate from the inlet 2 side and is stacked below the disk 5, and when the condensed water is stacked, the pressure of the stacked condensate gradually rises.
- the force for raising (5) acts, and at the same time, the temperature of the disk 5 in contact with the condensate drops to the same temperature as the condensate.
- the volume of the force decreases, which acts to raise the disk.
- the disk 5 closes the passage 4 while descending as shown in Fig. 1 (a), thereby preventing the outflow of steam.
- Disc type steam traps are designed to discharge condensate automatically as this process is repeated. In order to improve thermal efficiency, steam traps need to be designed to automatically discharge and remove only condensate without steam.
- the present invention is to solve the conventional problems, by combining the advantages of the conventional disk method and the orifice method to minimize the discharge of steam and facilitate the discharge of condensate, easy to maintain the steam trap for a long time It is an object to provide an orifice type disk steam trap.
- the orifice type disk steam trap there is an inlet and an outlet discharged to the outside and the condensate is introduced into the inside, the body between the inlet and the outlet vertically formed; A disk adapted to open and close the passage; A transformer chamber in which the disk is movable up and down; A disk discharge hole connected to an outlet of the transformer chamber to discharge condensed water when the disk is elevated; And an orifice portion between the passage and the outlet.
- the orifice portion it is preferable that the orifice-type nozzle inserted into the connection hole passing through the passage and the outlet is fixed to the connection hole by screwing.
- the orifice-type nozzle is provided in a cylindrical shape or at least a triangular polygon or more, the center is provided with a minimum discharge hole for discharging the condensate is preferably provided to discharge only the condensate.
- the discharge hole is formed in the form of a multi-stage hole whose diameter is gradually reduced in size so that the decompression is gradually made when the condensate flows in, the rear is the diameter so that the pressure of the condensate gradually increases during discharge It is preferable to be configured in the form of a multi-stage hole that is expanded in stages.
- the orifice nozzle provided in the orifice portion is preferably provided with a nozzle body screwed to the connection hole and an orifice nozzle inserted into the coupling hole penetrated through the nozzle body.
- the orifice type disk steam trap according to the present invention combines the advantages of the conventional disk type and the orifice type to minimize the discharge of steam and facilitate the discharge of condensate, and the maintenance of the steam trap can be easily used for a long time. Excellent effect
- the orifice-type orifice-type nozzle can always discharge even a small amount of condensate, there is an excellent effect that can prevent the breakage of the disk by preventing frequent operation of the disk for a small amount of discharge.
- the existing orifice nozzle is easily installed, it is possible to easily replace and use the existing orifice nozzle without having to manufacture a separate dedicated orifice nozzle, thereby providing excellent compatibility.
