Abstract

PROBLEM TO BE SOLVED: To provide a downward bucket type steam trap which may not cause valve leakage by increasing valve closing force. SOLUTION: A valve casing is formed by a body 1 and a cover 3, and an inlet 5, a valve chamber 4 and an outlet 14 are formed in the valve casing. A valve port 15 communicating the valve chamber 4 with the outlet 14 is formed in the upper part of the valve chamber 4. A downward bucket 9 having an introducing opening 11 in its lower part and an air releasing hole 10 in its upper part is stored in the inside of the valve chamber 4. The valve port 15 is opened/closed by a valve element 18 connected to the downward bucket 9 through a lever 17. When the valve element 18 closes the valve port 15, the upper surface of the downward bucket 9 abuts on the lower end of the valve element 18 so as to push the valve element 18 to the valve port 15, and the buoyancy of the downward bucket 9 acts as valve closing force on the valve element 18.

This forms an inlet, a valve chamber, and an outlet in the valve casing, and forms a valve port communicating with the valve chamber and the outlet in the upper part of the valve chamber,
A downward bucket having an inlet opening at a lower portion and a vent hole at an upper portion is accommodated in a valve chamber, and a valve port is opened and closed by a valve body connected to the downward bucket via a lever.

When condensate flows into the inlet and the supply of steam into the downward bucket stops, the steam in the downward bucket decreases due to cooling and condensation and escape from the vent holes, and the downward bucket loses buoyancy. The valve body opens the valve port via the lever, and the condensate in the valve chamber is discharged from the valve port to the outlet. When steam flows into the downward bucket due to the discharge of the condensate water, the downward bucket floats again, and the valve element 18 closes the valve port 15 via the lever 17.
Such an operation is repeatedly performed.

スチームトラップを提供することである。However, in the above-mentioned conventional apparatus, when the valve body is in the closed state in which the valve port is closed,
Since the valve closing force acting on the valve body is only the fluid pressure on the inlet side, there is a problem that the valve closing force is relatively weak and valve leakage is likely to occur. Therefore, a technical problem of the present invention is to provide a downward bucket type steam trap which does not cause valve leakage by increasing the valve closing force.

作動を繰り返して行う。The operation of the downward bucket type steam trap of the above embodiment is as follows. FIG.
Flows into the downward bucket 9 through the introduction hole 8, the downward bucket 9 rises by receiving buoyancy, and the valve element 18 closes the valve port 15 via the lever 17. In this state, the upper surface of the downward bucket 9 abuts against the lower end of the valve element 18 to press the valve element 18 against the valve port 15, and the buoyancy of the downward bucket 9 acts as a valve closing force on the valve element 18. . Then, when the condensate flows into the inlet 5 and the supply of steam into the downward bucket 9 stops, the steam in the downward bucket 9 decreases due to cooling and condensation and escape from the vent hole 10, and the downward bucket 9 9 loses buoyancy and descends, the valve element 18 opens the valve port 15 via the lever 17, and the condensate in the valve chamber 4 is discharged from the valve port 15 to the outlet 14. When steam flows into the downward bucket 9 due to the discharge of the condensate, the downward bucket 9 floats again, and the valve element 18 closes the valve port 15 via the lever 17. Such an operation is repeatedly performed.
