本発明は蒸気配管系から蒸気は逃さず復水のみ
を自動的に排水するスチームトラツプに於けるス
チームロツキングを解消する構造に関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a structure for eliminating steam locking in a steam trap that automatically drains only condensate without allowing steam to escape from a steam piping system.

発生する復水を自動的に排出するものであるが、

ングが起こる。 A steam trap automatically discharges condensate generated in steam piping and equipment that uses steam.
If steam remains in front of the trap, so-called steam locking occurs, in which the valve cannot be opened even though condensate is generated in the piping system and equipment used.
シリンダ乾燥機から復水を排出する場合やスチ
ームトラツプの入口側配管が立上つている場合に
はスチームロツキングが起こりやすい。 Steam locking is likely to occur when condensate is discharged from a cylinder dryer or when the piping on the inlet side of a steam trap is upright.

い。 For example, when discharging condensate from a cylinder dryer, the condensate is led out from the condensate pool in the cylinder using a siphon pipe, and then discharged using a steam trap attached to the end of the siphon pipe. Since the siphon pipe passes through the steam supply path, the condensate is heated and re-evaporated there. Also, after the condensate is discharged, the siphon pipe is filled with steam, so that the condensate accumulates in the cylinder. However, due to this steam, the trap remains closed and condensate cannot be discharged.

This is designed to allow a very small amount of steam to escape from an exhaust valve installed in the steam trap at all times, thereby allowing steam in front of the steam trap to escape, allowing condensate to flow into the trap and being discharged.

のである。Means for Solving the Problems The technical means of the present invention taken to solve the above-mentioned technical problems is to form a steam supply passage in the upper part of the casing to supply steam to steam-using equipment; an ejector, a water reservoir chamber extending downward from the opening of the jet flow portion of the ejector, an annular partition provided above the water reservoir chamber, and an annular partition between the partition wall and the valve casing outside the water reservoir chamber; forming a space, the upper part of the annular space is connected to the inlet of the fluid from the steam-using equipment, the lower part is connected to the water sump chamber, and the water sump chamber is connected to the opening of the jet flow section through a hole inside the partition; A turning deflector is placed in an annular space, and a valve is provided to discharge water accumulated in a water storage chamber.
作 用 上記の技術的手段の作用は下記の通りである。Effect The operation of the above technical means is as follows.

復水を排出ことができる。 Steam is supplied to steam-using equipment via an ejector formed in the steam supply passage. Fluid from the steam-using equipment enters the annular space through the inlet and is drawn into the jet flow section of the ejector through holes inside the bulkhead. When the fluid passes through this annular space, it is swirled by the deflector. Centrifugal force acts on the swirling fluid, and condensate has a larger mass than steam, so it is blown out of the swirling flow, hits the surrounding wall of the water storage chamber, flows down along the wall, and is discharged from the system by the drain valve. be done. The steam is drawn into the jet flow section of the ejector through the holes inside the partition and is again supplied to the steam-using equipment. Therefore, steam does not remain in front of the steam trap, and condensate can be quickly discharged.
発明の効果 本発明は下記の特有の効果を生じる。Effect of the invention The present invention produces the following unique effects.
蒸気を漏らさずに復水を排出できるので省エネ
ルギーであると共に、復水をエゼクタで吸引する
ので素早く排出でき、蒸気使用機器の生産性が向
上する。 Since condensate can be discharged without leaking steam, it saves energy, and since the condensate is sucked in by an ejector, it can be discharged quickly, improving the productivity of steam-using equipment.
旋回デイフレクタは環状の小部品であるから、

び蒸気使用機器に流入することもない。 Since the turning deflector is a small annular part,
Can be installed in narrow annular spaces. Furthermore, since the swirling deflector has good separation efficiency, condensate water does not flow back into the steam-using equipment.
