Abstract

PROBLEM TO BE SOLVED: To provide a thermal reaction type steam trap which can block perfectly even when a valve member seats on a valve seat member in an inclined condition. SOLUTION: A diaphragm 15 and a valve member 21 are communicated by a universal joint 20. Even though the valve member 21 is inclined when it seats on a valve seat member 8, the valve member 21 is contacted closely with the valve seat member 8 perfectly by the inclining of the valve member 21, and a leading-out passage 7 is blocked perfectly.

2. Description of the Related Art A thermally responsive steam trap using a temperature control element is disclosed, for example, in Japanese Patent Publication No. 60-46318. As can be understood from the publication, a temperature control element that forms an inlet, a valve chamber, and an outlet by casing, and includes a wall member, a diaphragm, an expansion medium enclosed between them, and a valve member connected to the diaphragm. Is disposed in the valve chamber, and the valve member is driven by the displacement of the diaphragm due to the expansion and contraction of the expansion medium to open and close the outlet passage formed at the opening end of the outlet on the valve chamber side.

When a high-temperature fluid having a temperature equal to or higher than a predetermined temperature flows into the valve chamber, the expansion medium expands, the diaphragm is displaced in the valve closing direction, and the valve member closes the outlet passage. This prevents the discharge of steam. When a low-temperature fluid having a temperature equal to or lower than a predetermined temperature flows, the expansion medium contracts, the diaphragm is displaced in the valve opening direction, and the valve member opens the outlet passage. As a result, condensate and air are discharged out of the system.

However, the heat-actuated steam trap of this type has a problem that the valve cannot be completely closed to cause vapor leakage. This is because when the diaphragm is displaced in the valve closing direction by the expansion of the expansion medium, the valve surface of the valve member may approach and seat in an inclined state that is not parallel to the valve seat surface of the outlet passage. This is because, when the seat is seated in a tilted state, it may not be possible to shift to a state parallel to the valve seat surface and complete contact may not be achieved with the valve seat surface.

The technical means of the present invention taken to solve the above technical problems is to form an inlet, a valve chamber and an outlet by casing, and to form a wall member, a diaphragm and both of them. A temperature control element composed of an expansion medium enclosed between the expansion medium and a valve member connected to the diaphragm is arranged in the valve chamber, and the valve member is driven by the displacement of the diaphragm due to the expansion and contraction of the expansion medium to open the valve chamber side opening end In the one for opening and closing the lead-out path formed in the above, there is a heat-actuated steam trap characterized in that the diaphragm and the valve member are connected by a universal joint.

The operation of the above technical means is as follows.
Since the valve member is connected to the diaphragm by a universal joint, even if the valve surface of the valve member is seated in an inclined state that is not parallel to the valve seat surface of the outlet passage, it is necessary to match the valve seat surface. In that case, the valve can be properly tilted and brought into intimate contact, and the valve can be completely closed.

The operation of this embodiment is as follows. When the fluid temperature in the valve chamber 3 becomes lower than a predetermined value due to heat dissipation, or when a low temperature fluid flows into the valve chamber 3 from the inlet 4,
The expansion medium 16 contracts, and the valve member 21 is also separated from the valve seat member 8 by applying the fluid pressure at the inlet 4 to open the outlet passage 7. Thereby, low-temperature condensate and air are discharged from the outlet 5.

When the temperature of the fluid flowing into the valve chamber 3 rises due to the discharge of the low temperature fluid, the expansion medium 16 expands, causing the valve member 21 to be displaced downward through the diaphragm 15 and 21 is seated on the valve seat member 8 to close the outlet passage 7 and prevent vapor from leaking. Even if the valve member 21 is tilted when it is seated on the valve seat member 8 due to the expansion of the expansion medium 16, the valve member 21 is connected to the diaphragm 15 by the universal joint 20, so it should be tilted in all directions. Thus, the valve is brought into close contact with the outlet path 7 and the valve is completely closed.
