Abstract
Description
本発明は、被制御流体で加熱冷却され、その温度に応じて変形する感温部材により弁口を開閉する温度応動弁に関する。本発明の温度応動弁は所定温度以上あるいは以下の流体を系外に排出したり、複数の流体を混合して所定温度の流体にしたりする場合に用いられ、特に所定温度以下の復水を自動的に排出する温調トラップとして用いる場合に好適なものである。 The present invention relates to a temperature-responsive valve that opens and closes a valve opening by a temperature-sensitive member that is heated and cooled by a controlled fluid and deforms according to the temperature. The temperature responsive valve of the present invention is used when discharging a fluid at or below a predetermined temperature out of the system or mixing a plurality of fluids into a fluid at a predetermined temperature. It is suitable when used as a temperature control trap that is discharged automatically.
従来の温度応動弁は、弁ケーシングで入口と弁室と出口を形成し、弁室と出口の間に弁室と出口を連通する弁口を設け、弁口を貫通して弁軸を配置し、弁口を出口側から開閉する弁体を弁軸に一体に設け、弁室内の弁軸の周りに感温部材を配置し、感温部材の変形作用で弁軸を軸方向に変位させて弁体で弁口を開閉するものである。 A conventional temperature responsive valve has an inlet, a valve chamber, and an outlet formed by a valve casing, a valve port that communicates between the valve chamber and the outlet is provided between the valve chamber and the outlet, and a valve shaft is disposed through the valve port. The valve body that opens and closes the valve port from the outlet side is provided integrally with the valve shaft, a temperature sensitive member is arranged around the valve shaft in the valve chamber, and the valve shaft is displaced in the axial direction by the deformation action of the temperature sensitive member. The valve opening is opened and closed by a valve body.
上記従来の温度応動弁においては、弁体が離着座して開閉する弁口のシール面に流体中のゴミやスケール等の異物が付着すると、弁体が弁口を完全シールする全閉位置に変位できず、弁口に次第に異物が堆積して弁口が次第に狭められて排出流量の減少、ひいては弁口が詰まってしまうという問題点があった。
解決しようとする課題は、弁口に異物が堆積しない温度応動弁を提供することである。 The problem to be solved is to provide a temperature responsive valve in which foreign matter does not accumulate in the valve port.
本発明は、弁ケーシングで入口と弁室と出口を形成し、弁室と出口の間に弁室と出口を連通する弁口を設け、弁口を貫通して弁軸を配置し、弁口を出口側から開閉する弁体を弁軸に一体に設け、弁室内の弁軸の周りに感温部材を配置し、感温部材の変形作用で弁軸を軸方向に変位させて弁体で弁口を開閉するものにおいて、弁体の弁口とは反対側に外部から弁体を弁口方向に押し付け可能な操作部材を設け、操作部材により弁体を弁口に押し付けて弁口に付着する異物を弁体で押し退けることを特徴とする。 In the present invention, an inlet, a valve chamber, and an outlet are formed by a valve casing, a valve port that communicates between the valve chamber and the outlet is provided between the valve chamber and the outlet, a valve shaft is disposed through the valve port, A valve body that opens and closes from the outlet side is provided integrally with the valve shaft, a temperature sensing member is disposed around the valve shaft in the valve chamber, and the valve shaft is displaced in the axial direction by the deformation action of the temperature sensing member. When opening and closing the valve port, an operating member is provided on the side opposite to the valve port of the valve body that can press the valve body from the outside in the direction of the valve port, and the valve body is pressed against the valve port by the operating member and attached to the valve port. It is characterized in that the foreign matter to be pushed is pushed away by the valve body.
本発明は、弁口に付着する異物を弁体で押し退けることにより、弁口に異物が堆積しないので、排出流量の減少や弁口が詰まってしまうことがないという優れた効果を生じる。 According to the present invention, the foreign matter adhering to the valve opening is pushed away by the valve body, so that the foreign matter does not accumulate on the valve opening, so that an excellent effect is obtained that the discharge flow rate is not reduced and the valve opening is not clogged.
本発明の温度応動弁は、弁体の弁口とは反対側に外部から弁体を弁口方向に押し付け可能な操作部材を設け、操作部材により弁体を弁口に押し付けて弁口に付着する異物を弁体で押し退けるものである。すなわち、大きな力で弁体を弁口に押し付けて弁口に付着する異物を弁体で押し退けることにより弁口に異物が堆積しない。 The temperature responsive valve of the present invention is provided with an operating member capable of pressing the valve body in the direction of the valve mouth from the outside on the side opposite to the valve mouth of the valve body, and presses the valve body against the valve mouth by the operating member and adheres to the valve mouth. The foreign object to be pushed away with the valve body. That is, foreign matter does not accumulate on the valve opening by pressing the valve body against the valve opening with a large force and pushing away the foreign matter adhering to the valve opening with the valve body.
上記の技術的手段の具体例を示す実施例を説明する(図1参照)。入口1と出口2を有する本体3に蓋4を締結して内部に弁室5を有する弁ケーシングを形成する。弁室5には入口1が通孔6を通して連通し、出口2が通孔7と弁口8と通孔9を通して連通する。通孔7と弁口8は本体3にねじ結合した弁座部材10に形成する。弁室5内に入口1から流入する流体の流れ方向を規制し、流体中の異物を捕捉するスクリーン11を配置する。弁口8を貫通して弁軸12を配置する。弁軸12の下端には弁口8を出口2側から開閉する円錐状の弁体13を一体に設ける。
An embodiment showing a specific example of the above technical means will be described (see FIG. 1). A
弁室5内の弁軸12の周りで、弁棒12の上部にねじ結合した座金15の下端面と弁座部材10の上端面の間に感温部材としてのバイメタル積層体16を配置する。バイメタル積層体16はバイメタルディスクを湾曲方向を変えて組み合わせた2枚で一対とし、それを複数対重ねたものである。本体3の下端に操作部材17をOリング18を介して進退調節可能に配置する。操作部材17を押し上げて操作部材17の上面を弁体13の下面に当接させ、更に操作部材17を押し上げて大きな力で弁体13を弁口8に押し付けて弁口8に付着する異物を弁体13で押し退ける。
Around the valve shaft 12 in the
流体は入口1から通孔6を通って弁室5に入り、バイメタル積層体16の周りを流れ、通孔7と弁口8から通孔9を通って出口2に流出する。バイメタル積層体16は周囲の流体の温度が上昇して高温に加熱されると、各バイメタルディスクが湾曲してその度合が大きくなり積層方向に伸張する。これに伴い、弁軸12が上方に変位し、次第に弁体13が弁口8に近づいて弁口8の開度が小さくなり、終わりには弁体13が弁口8を閉じる。弁室5の流体の温度が低下すれば、バイメタル積層体16は湾曲力が小さくなり積層方向に収縮する。これに伴い、弁軸12が下方に変位し、弁体13が弁口8から離れて弁口8が開けられ、弁室5の流体が出口2に排出される。
