[Industrial use]

The present invention relates to an operational type steam trap device for discharging a drain generated by connecting to a steam-using device or a steam piping system.

[Prior art]

The steam trap apparatus which connected the orifice trap to the electric outlet of Y type strainer with the inlet of a drain, the outlet of a drain, a branch, a cylindrical center which connected each end to the said inlet and a branch, etc. has already been said. The steam trap device filters the drain flowing from the inlet through a tubular filter to catch foreign substances such as iron and rust that block the orifice in the orifice trap with a filter, and only the drain is supplied to and discharged from the orifice trap through the outlet. Nevertheless, there is a foreign object that penetrates the tubular center, and the foreign material can cause the orifice trap to block the orifice. Therefore, an ejector is connected to the basin and an opening / closing valve downstream thereof. If the inlet side in front of the orifice is connected with a communication tube, and the orifice is clogged with foreign matter, open the valve to open the entire amount of the drain flowing from the inlet to the Y-strainer through the inside of the cylindrical filter, through the basin, and into the ejector. Negative pressure is generated by to remove foreign substances clogged with orifice.

[Problem to Solve Invention]

The conventional apparatus cannot determine whether or not the orifice of the orifice trap is clogged with foreign matter, so that the drain stays without draining and the water heater phenomenon occurs in the steam piping system, or the heat transfer rate is lowered in the steam using device. Realizing that the seal is clogged with foreign matter, the opening and closing valve opens and sucks and removes the foreign matter, which can only be a popular therapy.

[Means for solving the problem]

The present invention focuses on the fact that the foreign material is not captured by the cylindrical filter of the y-type strainer and passes through the filter because of the high pressure, and the internal pressure of the y-type strainer is made low so that the foreign material passes through the cylindrical filter. The problem of the conventional apparatus is solved, and a drain inlet, a drain outlet, a basin, the inlet and the outlet is characterized in that the orifice made of a small diameter hole. It is more effective to connect the orifice trap to the outlet of the y-strainer.

[Example]

1 is an embodiment of claim 1 of the present invention, and FIG. 2 is an embodiment of claim 2 of the present invention. FIG. 10 is a drawing of the inlet 11 of the drain, the outlet 12 of the drain, the branch 13, the inlet 11 and the branch of FIG. The y-type strainer is a cylindrical filter with ends connected to 13, and the cylindrical filter is, as you know, a plurality of small holes of cylindrical filter. Opening and closing valves 15, such as ball valves, are connected to the basin 13 and normally closed. Drain flows from the inlet 11 into the interior of the cylindrical filter 14, and foreign matters such as iron and rust that are mixed when the filter is removed from the filter hole in the cylindrical surface to the hollow portion in the y-type strainer are captured by the filter.

The drain from which the foreign material is removed in this way is discharged from the hollow part of the y-type strainer via the outlet part 13.

When the pressure of the drain flowing through the inlet 11 into the cylindrical center 14 is high, some foreign matter mixed in the drain exits the cylindrical center hole and exits the hollow part of the y-type strainer like the drain to discharge a certain amount of drain continuously. For this reason, when the orifice trap is connected to the outlet, the foreign material closes the orifice of the orifice trap.

The conventional y-type strainer inlet has a female screw socket for connecting the upstream pipe of the drain and the inlet is open to approximately the same diameter as the female screw of the socket. The outlet also has a screwed socket for connecting the downstream pipe to the drain and the orifice trap, and the outlet is open with the same diameter as the female screw.

About this part In the present invention, the inlet and outlet of the y-type strainer have sockets 16 and 17 made of female screws, respectively.

It is preferable that the diameter of the small diameter hole 21 of the inner orifice 23 of the inlet 11 is set to a minimum pore size, that is, 2.5-3 mm, in which foreign matter cannot be blocked. The diameter of the small diameter hole 22 of the orifice 24 in the outlet 12 is preferably 2.5-3 mm, which is the same as the small diameter hole of the inlet when the orifice trap is not connected to the outlet.

In this way, if the inlet 11 and outlet 12 of the y-strainer are made with O-reduce 24 consisting of small-diameter 21 and 23 and small-diameter 22, the drain flowing into the cylindrical orifice from the inlet 11 through the small-diameter 21 is the y-strainer. The pressure decreases due to adiabatic expansion in the interior and large space. Therefore, since the pressure of the drain passing through the cylindrical surface center hole of the cylindrical 14 is lowered, foreign matter mixed in the drain is trapped over all the centers, and cannot exit the outlet of the y-type strainer hollow.

12 Orifice trap 18 is connected to the outlet made from the orifice 24 of the small diameter hole 22 by Claim 2, and the other pressure reduction chamber 20 is formed between the small diameter hole of the outlet and Orifice 19 of the orifice trap. Therefore, the pressure of the drain that flows into the cylindrical orifice from the inlet 11 through the small diameter hole 21 and exits the small hole of the cylindrical surface of the cylindrical orifice filter is reduced again, so that the foreign matter contained in the drain is more effectively caught by the filter.

The ball valve 15 connected to the basin 13 is regularly opened to remove and discharge the foreign matter caught in the cylindrical surface of the tubular hole of the tubular filter by the drain flowing from the inlet to the barrel.

To make an orifice with small holes in the inlet 11 and outlet 12 of the y-strainer, you can either make a y-strainer into a cast unit and form a hole, or make an orifice plate in the y-trainer and screw it.

As described above, according to the steam trap device of the present invention, foreign matter mixed in the drain is reliably caught by the cylindrical filter of the y-type strainer and cannot be discharged from the outlet. Therefore, the water heater phenomenon in a steam piping system and the fall of the heat transfer rate of a steam use apparatus are prevented reliably.
