[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trap device for discharging condensate generated in a steam piping system, and more particularly to a means for using a disk type steam trap as a trap to blow a primary fluid. A disc-type steam trap is used to discharge only the condensate without escaping the steam from the steam system.However, since a large amount of air and low-temperature condensate and steam are generated at the beginning of air supply, equipment that uses steam It is necessary to blow in a short time in order to shorten the start-up time. However, there is a problem that it takes a long time to blow since the valve closes when low-temperature steam flows in and does not open again unless water condenses.

[0002]

Therefore, conventionally, a bypass passage is formed by connecting the upstream side and the downstream side of a disk type steam trap, and an upstream valve is arranged on the upstream side, a downstream valve is arranged on the downstream side, and a bypass valve is arranged on the bypass passage. I was In normal times, open the upstream and downstream valves, close the bypass valve, and automatically discharge only the condensate water with the disc-type steam trap. If a large amount of low-temperature steam, such as the start of air supply, is generated, the bypass valve Open and blow quickly.

[0003]

[Problem to be solved by the invention] With the above structure,
Since it is necessary to form a bypass passage and arrange a bypass valve and the like, there is a problem that equipment costs increase. The technical problem of the present invention is, therefore, to be able to blow in a short time without forming a bypass passage.

[0004]

Means for Solving the Problems The technical means of the present invention taken to solve the above technical problem is to form a valve chamber in which an inlet and an outlet communicate with each other by a casing, and open a flow hole in the valve chamber. The valve ball is arranged, and the valve ball can be rotated 180 degrees by the valve shaft so that the inlet and the outlet communicate or block.
Together to allow disconnection, the valve ball and integrally into the flow hole
In this embodiment, a rotating disk-type steam trap is disposed, and the inlet of the disk-type steam trap is connected to one port of the circulation hole, and the outlet is connected to the other port.

[0005]

The operation of the above technical means is as follows.
In normal times, the valve shaft is rotated, and the inlet and outlet are in communication with each other through the flow hole of the valve ball.The inlet and the inlet of the disc-type steam trap communicate with each other, and the outlet of the disc-type steam trap communicates with the outlet. Use at a location where the outlets communicate. In this case, the fluid from the inlet is discharged by the well-known operation of the disk-type steam trap and only the condensate is discharged to the outlet. If a large amount of low-temperature steam or condensate is generated at the start of air supply, etc., rotate the valve ball 180 degrees so that the inlet and the outlet of the disk type steam trap communicate with each other, and the flow of the disk type steam trap flows. Make sure that the entrance and exit are in communication. In this case, since the fluid from the inlet flows in from the outlet of the disc-shaped steam trap, the disc-shaped steam trap always keeps the valve open and blows the fluid from the inlet to the outlet in a short time. If the valve is rotated 90 degrees from the position of the valve ball, the inlet and outlet are shut off.

[0006]

An embodiment showing a specific example of the above technical means will be described (see FIG. 1 ). An end member 2 is attached to the main body 1 with bolts 3 to form a casing. An inlet 4 is formed in the main body 1, an outlet 5 is formed in the end member 2, and a valve chamber 6 communicating the inlet 4 and the outlet 5 is formed inside the casing.

[0007] A valve ball 8 having a flow hole 7 formed therein is disposed in the valve chamber 6. Annular valve seats 9 and 10 are arranged on the inlet 4 side and the outlet 5 side of the valve ball 8, respectively. Key groove 11 on valve ball 8
And a key portion 1 at the lower end of the valve shaft 12 penetrating the main body 1.
3 is engaged. A handle (not shown) is attached to the valve shaft 12 so that the valve ball 8 can rotate. Reference number 1
Reference numeral 4 denotes a gasket for maintaining airtightness between the main body 1 and the valve shaft 12.

[0008] A disk type steam trap 15 is disposed in the flow hole 7. The disk type steam trap 15 is fixed to a wall member 16 formed in the flow hole 7 with a bolt 17.
A through hole 26 is formed in the wall member 16. The casing of the disc type steam trap 15 is composed of the valve seat body 18 and the valve seat body 1.
8 and a lid 19 screwed to the transformer chamber 2 between the two.
0 is formed. The valve seat body 18 has an inlet 21 penetrating from the lower part to the center of the variable pressure chamber 20 and an outlet 22 opening around the inlet 21. An annular inner ring valve seat 23 is formed between the inlet 21 and the outlet 22, and an annular outer ring valve seat 24 is formed outside the outlet 22. Valve disk 2 in the transformation chamber 20
Accommodates 5

The operation of the above embodiment is as follows. Normal time is used in the state shown in FIG. That is, circulation holes 7 of the valve ball 8 in communication with the inlet 4 and outlet 5, through the inlet port 21 communicates the inlet 4 and the disc type steam trap 15, is the outlet 2 2 and the outlet 5 of the disc type steam trap 15 Communicating. Therefore, in this case, the fluid from the inlet 4 is discharged by the well-known operation of the disc-type steam trap 15 to the outlet 5 with only the condensate being discharged. When a large amount of low-temperature steam or condensed water is generated at the start of air supply or the like, the valve ball 8 is rotated 180 degrees from the state shown in the drawing, so that the inlet 4 communicates with the outlet 22 of the disc-type steam trap 15 and the disc-type steam trap 15 communicates. The steam trap 15 is set at a position where the inlet 21 and the outlet 5 communicate with each other. In this case, since the fluid from the inlet 4 flows in from the outlet 22 of the disc-type steam trap 15, the disc-type steam trap 15 always keeps the valve open, and the fluid from the inlet 4 is blown to the outlet 5 in a short time. I do. When the valve ball 8 is rotated 90 degrees from the state shown in the figure, the inlet 4 and the outlet 5 are shut off.

[Effects of the Invention] The present invention has the following specific effects. In the present invention, there is no need to attach a bypass passage or a valve attached thereto, so that equipment costs can be significantly reduced and piping space can be reduced. In the related art, the operation of the upstream valve, the downstream valve, and the bypass valve is required according to the purpose, but in the present invention, only one valve ball needs to be operated, and the opening and closing operation is simplified. Since the disc-type steam trap is arranged in the flow hole of the valve ball, while the inlet side is filled with steam, the heat can prevent condensation of steam in the transformer chamber of the disc-type steam trap. Therefore, there is no possibility that the valve is opened prematurely before the condensed water is generated on the inlet side. Disc type steam
If the trap cannot be closed, rotate the valve ball.
To prevent steam leakage by shutting off the inlet and outlet.
Can stop and waste expensive energy
