ない。Problems that the invention aims to solve: The disc type steam trap reduces the heat supply from the steam that has accumulated in the variable pressure chamber above the disk valve, causing the pressure in the variable pressure chamber to drop, and the valve opens due to the pressure difference that occurs above and below the disk valve. leading to. After that, the condensate is discharged, and sufficiently high-temperature condensate or steam passes through the lower part of the disc valve at high speed, creating a pressure difference between the top and bottom of the disc valve, leading to the valve closing. As is clear from this operating principle, high-temperature, high-velocity condensate flows into the disk valve outlet side, and the force is tremendous, especially if it is a high-pressure disk type steam trap. Furthermore, since a sudden pressure difference occurs in the condensate discharged to the outlet side, the condensate re-evaporates all at once, producing a very loud impact sound. However, Jikko 57-
If the method of providing a sound absorber in the cavity as disclosed in No. 24578 is adopted, a sound absorption effect can be expected, but the flow resistance of the fluid will increase, especially if it is a high-pressure disk type steam trap. This may cause irregular operation or valve closing failure.

The inside thereof communicates with an inlet 3 and an outlet 4 provided in the body 1. The valve body unit 5 screwed into the hole communicating with the outlet 4 of the body 1 is common to the inner ring seat 7 that limits the inner edge of the inlet hole 6 communicating with the inlet 3 and the outer ring seat 8 surrounding the inner ring seat 7. A variable pressure chamber 1 houses a disc valve 9 mounted on the disc valve 9 and controls the movement of the disc valve 9 into and out of the seat.
0 to the outlet 4 of the body 1.
It is formed by screwing into a valve seat 13 provided with an outflow hole 12 communicating with the valve seat 13.

りボデイ１への侵食は阻止できる。Action: Flows in from the inlet 3 and connects the cover 2 and the valve body unit 5.
When the internal pressure of the variable pressure chamber 10 decreases and the disc valve 9 is overcome by the internal pressure of the inlet hole 6 and opens, the accumulated condensate passes from the inlet hole 6 to the outlet hole 12. The inflowing condensate flowing into the expansion chamber 14 has a considerable inflow velocity and violently collides with the bottom 17 of the member 15, but in this embodiment, since it is not flat but has an angle, the force is dispersed and the bottom 1
The erosion of the member 7 is reduced, and the pin 18 prevents the member 15 from rotating due to vibration. Also, member 1
Since the parts 5 are loosely locked, even if erosion occurs, the erosion to the body 1 can be prevented by periodically replacing the member 15.

出孔１２の径よりも大きくする必要がある。 Furthermore, an orifice 16 is provided on the side wall of the member 15, and the condensate that has once re-evaporated when flowing into the expansion chamber 14 from the outflow hole 12 flows once again through the orifice 16.
This two-stage throttling system effectively reduces the sound of condensate discharge without significantly increasing flow resistance, and also reduces the flow velocity in two stages to prevent erosion. can. Note that the orifice 16 needs to be larger in diameter than the outflow hole 12 in order not to increase flow resistance.
