Description

Multi-Stage Orifice Steam Trap {SERIES MULTISTAGE ORIFICE STEAM TRAP}

The present invention relates to a multi-stage orifice steam trap, and more particularly, it relates to a multi-stage orifice steam trap having a plurality of steam traps each having an orifice outlet of the same orifice without reducing the diameter of the orifice outlet, And a multistage orifice steam trap that can be applied under any conditions.

Generally, a steam trap for discharging a drain generated by the influence of a low temperature external temperature of steam in a pipe supplied by a constant pressure is installed in a steam using appliance, a steam pipe, and the like. On the other hand, the orifice steam trap maintains the drain hole occupying the orifice hole and prevents leakage of steam.

The orifice steam trap is economically advantageous because it minimizes steam leakage, does not require an operating port, has a small heat generating area, and has an improved heat transfer coefficient with respect to the heating body. However, in the conventional orifice steam traps, fine particles such as scale existing in the drain accumulate in the periphery of the orifice hole or the drain discharge passage, so that the orifice hole is clogged or the flow path is narrowed, and the drain is not smoothly discharged.

In other words, conventionally, since the orifice hole is formed from the flat portion toward the flow path, the fine particles accumulate on the flat portion around the hole to form a mountain during the passage of the drain through the orifice hole, This is a clogging problem.

Further, since the fine particles are accumulated on the wall surface of the drain discharge flow passage, the flow passage is narrowed, that is, the diameter of the flow passage is narrowed, and drain discharge is prevented. To solve such a problem, there is a technique of Patent Document 1 which was developed and patented by the present applicant.

This is characterized in that the drained drain keeps the orifice outlet occupied and prevents leakage of steam. Such an orifice steam trap should be able to determine the pressure of the steam and the condensate volume of the generated drain and select the orifice outlet of the caliber corresponding to it.

However, there is a difficulty in selecting a suitable steam trap for the orifice outlet at a constant pressure, where the amount of the drain condensate often changes, and in some cases, it is not possible to apply the steam trap at an extreme.

In the case of an appropriate orifice outlet, the resulting drain condensate serves as a sealing material to prevent leakage of the vapor through the orifice outlet and is connected to the discharge of a smooth condensate, but under such conditions, the condensate remains or the vapor leaks This is because they are concerned. Among these drawbacks, when the amount of the drain condensate is larger than expected, the condensate remains.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same components are denoted by the same reference symbols whenever possible. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

As shown in FIG. 19, the orifice steam trap according to the present invention is installed on the steam transportation pipe 1 or the like, and drains generated from steam by the ambient temperature of low temperature. At this time, the steam should be shut off and not leak. That is, as shown in the drawing, the orifice steam trap of the present invention is installed in a branch pipe 2 branching from a steam pipe 1 or the like, and can receive steam and drain only, thereby enhancing energy efficiency.

As shown, the multi-stage orifice steam trap of the present invention can be configured in two types. That is, as shown in FIGS. 1 to 9, the first orifice steam trap means 10 is provided with a separate body as shown in FIGS. 10 to 15 .

First, the operation of the first orifice steam trap means 10 as a body will be described in detail.

In the multi-stage orifice steam trap according to the present invention, the first orifice steam trap means 10 serves as one steam trap, and at least one steam trap is provided.

That is, as shown in the drawing, the first orifice steam trap means 10 has a rod shape and an insertion groove 10g is formed through the center in the longitudinal direction, and a first orifice outlet 10i is formed at one end have.

The end of the first orifice steam trap means 10 on which the first orifice outlet 10i is formed further includes a first conical protrusion 10p formed outwardly protruding from the center of the first conical protrusion 10p, So that the first orifice outlet 10i is formed.

One or more second orifice steam trap means 20 and at least four third orifice steam trap means 30 are inserted into the insertion groove 10g formed in the first orifice steam trap means 10. [

The other end of the first orifice steam trap means 10 is provided with a stop means 40 for securing the second and third orifice steam trap means 20, And the stopper means 40 and 40 are formed at the center of the stopper means 40 so that the threaded portions formed on one end of the inner wall of the insertion groove 10g are screwed And tightened.

The second orifice steam trap means 20 is inserted at a distance from the bottom 10b of the insertion groove 10g of the first orifice steam trap means 10 so that the bottom 10b of the insertion groove 10g, An orifice hole 10h is formed.

The grooves 20g and 30g are formed at one end of the second orifice steam trap means 20 and at one end of the third orifice steam trap means 30, And the grooves 20g and 30g are closed by the other end of the third orifice steam trap means 30 and the stopper means 40 to form an orifice hole having the same function as the orifice hole 10h do.

Of course, second and third orifice outlets 20i and 30i are formed at the other end of the second orifice steam trap means 20 and the third orifice steam trap means 30, respectively, The orifice hole 10h formed by the insertion groove 10g of the steam trap means 10 and the second orifice steam trap means 20 and the groove 20g of the second and third orifice steam trap means 20, And 30 are communicated with each other.

The second orifice steam trap means 20 and the third orifice steam trap means 30 have the same structure as shown in FIG. 1 to FIG. 10. Hereinafter, the second orifice steam trap means 20, The description of the third orifice steam trap means 30 will be omitted.

The second orifice steam trap means 20 has a rod shape and is inserted into the insertion groove 10g of the first orifice steam trap means 10 so as to be connected to the second orifice steam trap means 20, Four or more third orifice steam trapping means 30 are arranged in a row at the top.

As shown in the drawing, the second orifice steam trap means 20 has a second orifice outlet 20i formed at one end thereof and an open end at the other end thereof. The end portion of the second orifice outlet 20i is protruded toward the outside A second conical protrusion 20p is formed.

The second orifice outlet 20i extends through the second conical protrusion 20p and is formed into a trumpet shape having a groove 20g and a gradually enlarged inner diameter as shown in the figure.

The second orifice steam trap means 20 is provided on the wall surface of the insertion groove 10g of the first orifice steam trap means 10 opposed to the one end of the second orifice steam trap means 20, A step 10k is formed to form a step 10h. That is, the step 10k supports the one end of the second orifice steam trap means 20 and the other end of the second orifice steam trap means 20 between the bottom 10b of the first orifice steam trap means 10 and the one end of the second orifice steam trap means 20. [ So that the orifice hole 10h is formed.

A spacer 10r is provided between the step 10k formed in the first orifice steam trap means 10 and the other end of the second orifice steam trap means 20 so that the first orifice steam trap means 10, The orifice hole 10h is enlarged to a portion where the second orifice steam trap means 20 is coupled and leakage of steam or condensate is prevented.

The spaces 20r and 30r are provided not only between the second orifice steam trap means 20 and the third orifice steam trap means 30 but also between the adjacent third orifice steam trap means 30 .

As shown in Fig. 3, the bottom 10b of the insertion groove 10g formed in the first orifice steam trap means 10 according to the present invention having the above-described structure is formed by forming the bent portion 10m in the middle desirable. That is, the bent portion 10m has a shape in which the diameter gradually increases toward the inside of the insertion groove 10g, and the diameter of the first orifice outlet 10i is suddenly enlarged. When the first orifice outlet 10i is suddenly enlarged, the flow rate of the drain passing through the first orifice outlet 10i is further increased, so that the discharge ability of the drain is further improved and the accumulation of fine particles on the wall surface of the orifice hole 10h can be prevented will be. That is, the outlet of the first orifice outlet 10i is widened and the angle of spray is further enlarged, so that the accumulation of the particulates can be more effectively prevented.

The bent portion 10m may be formed in two or more stages as shown in Fig. The bent portion 10m is formed in two or more steps so that the diameter gradually increases. That is, since the diameter of the first orifice outlet 10i is suddenly enlarged and the flow rate of the drain passing through the first orifice outlet 10i is increased more and more, the discharge ability of the drain is further improved and the fine particles are accumulated on the wall surface of the orifice hole 10h . That is, the outlet of the nozzle 1 outlet 10i is widened to further expand the angle of spray, thereby more effectively preventing the accumulation of fine particles.

Further, as shown in Fig. 5, the bottom 10b of the first orifice outlet 10i may be inclined. In other words, by forming the bottom 10b obliquely, the holes formed by the bottom are enlarged toward the orifice hole 10h to form a funnel shape and coincide with or coincide with the spray angle of the orifice hole 10h, The accumulation is more effectively prevented and the corner portion 10c formed by the wall surface and the inner surface of the orifice hole 10h is not large and falls within the spraying force range of the drain.

6, the inner wall of the insertion groove 10g of the first orifice steam trap means 10 may be inclined inwardly from the bottom 10b. That is, the diameter of the orifice hole 10h may be increased toward the second orifice steam trap means 20. [ When the insertion groove 10g is inclined in this way, the same effect as that of the tapered first orifice outlet 10i is produced in the tapered orifice hole 10h, so that the flow rate of the drain passing through the orifice hole 10h becomes faster Drain discharge capability is greatly improved, and accumulation of fine particles on the wall surface of the orifice hole 10h is greatly prevented. In addition, since the corner portion 10c is adjacent to the outlet of the orifice hole 10h and a rapid eddy current is generated, accumulation of fine particles on the inner surface of the corner portion 10c and the orifice hole 10h can be largely prevented.

A part of the inner wall of the insertion groove 10g of the first orifice steam trap means 10 may be formed as an annular groove as shown in Fig. That is, if an annular groove is formed in the wall surface of the orifice hole 10h, the momentum is changed by changing the flow of the drain to induce the turbulence, to induce the impulsive force, or to induce the flow of the drain. Thus, accumulation of fine particles on the wall surface of the flow path 113 can be effectively prevented.

As shown in the figure, one annular groove may be formed and a curve may be formed by giving a curve to the corner. Such an annular groove induces an egg movement from the inside, and an impact force at a corner portion adjacent to the bottom 10b Thereby effectively preventing the accumulation of fine particles on the wall surface of the orifice hole 10h.

As shown in Fig. 8, the annular grooves may be formed in succession. By forming the two annular grooves in this way, it is possible to more effectively prevent the accumulation of fine particles on the wall surface of the orifice hole 10h by generating turbulence and impact force continuously, as compared with the case where only one annular groove is formed. At least three of the annular grooves may be formed.

Further, as shown in FIG. 9, a part of the inner wall of the insertion groove 10g of the first orifice steam trap means 10 can be formed into a plurality of annular grooves densely. The annular groove forms a curved shape by forming a semicircle or arcuate shape. The annular groove generates turbulence and an impact force in the orifice hole 10h, thereby accumulating fine particles on the wall surface of the orifice hole 10h In a very effective manner.

The annular groove may be formed in a spiral shape (not shown).

As shown in FIGS. 10 and 11, the first orifice steam trap means 10 is formed by forming a plurality of flat surfaces 11 on which a tool such as a monkey spanner or a pie french is threaded, . The plane 11 may be formed by cutting or grinding the outer periphery of the circular first orifice steam trap means 10, and may be formed in a plurality of lengths along the length of the first orifice steam trap means 10 so as to intersect with each other, 1 orifice steam trap means 10 can be loosened or tightened to greatly improve workability.

The present invention is directed to a series of multi-stage orifice steam traps for the purpose of reducing the pressure, and as a result, there is a certain reduction in pressure per one orifice steam trap means (10), (20) and (30). This phenomenon is a depressurization phenomenon caused by a labyrinth effect (maze).

This is because, when the drain condensate generated under a certain pressure is discharged to a lower pressure, the liquid condensate is re-evaporated and vaporized, and this is called a re-evaporated steam.

However, in the course of changing from liquid to gas, there is an instantaneous increase in volume, which increases the volume of the condensate to about 1000 times the volume of the drain condensate. The re-evaporated vapor, whose volume is momentarily enlarged in the limited orifice hole 10h after passing through the orifice outlet 10i, is inevitably discharged to the orifice outlet 20i (30i) having the same orifice at the lower end, which is the only passage, The effect of decompression is due to the stagnation phenomenon that occurs during the process.

When the drain condensate reaching the lowermost groove 30g that performs the function of the orifice hole 10h while the process is progressing in multiple stages is in a state where the ability of the re-evaporation steam is almost lost or absent, the amount of the generated condensate is calculated If more than a certain diameter, ie more than the expected amount of condensate generated in the design, will fill all the orifice holes in the multi-stage with condensate. That is, the orifice hole 10h and the grooves 20g and 30g are filled with the drain condensate.

In this case, the depressurizing effect due to the labyrinth effect of the multi-stage and the stress of the capillary phenomenon are lost, so that the condensed water is discharged to the one end of the orifice, that is, the amount of condensate discharged by the orifice steam trap means 10, It does not. On the other hand, when the discharge of the condensate proceeds smoothly and the condensate amount of the design condition becomes, the labyrinth effect by the original multi-stage and the stress of the capillary phenomenon are revived and the decompression function is normally restored.

Therefore, according to the present invention, when the diameter of the orifice outlets 10i, 20i, 30i is selected on the basis of the minimum condensed liquid amount, it is possible to discharge up to the discharge amount of the single orifice outlet 10i so that the amount of drain condensate is constant The most serious disadvantage of conventional orifice steam traps is that it is difficult to discharge the condensate properly. For this reason, the present invention can be applied under any conditions.

As described above, the multi-stage orifice steam trap according to another aspect of the present invention includes a separate body 100, and is configured as shown in FIGS. 11 to 17.

The body 100 has a rod shape as shown in the drawing, and an insertion groove 100g is formed at one end.

The workability can be greatly improved by allowing the body 100 to be loosened or tightened at any angle.

As shown in the figure, one end of the body 100 is provided with a jaw-like bottom 100b. At the other end of the insertion groove 100g, a stopper means 400 for closing a mouth of the end of the insertion groove 100g is installed Respectively.
