Description
本発明は、感温部材の周囲を流下する流体の温度に応じて、感温部材が変形することで弁口を開閉弁することのできる温度応動弁に関する。 The present invention relates to a temperature responsive valve capable of opening and closing a valve port by deforming a temperature sensitive member according to the temperature of a fluid flowing down around the temperature sensitive member.
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口を設けて、当該弁口に対向する位置に弁体を取り付け、当該弁体部分に刃物を設けると共に、弁体を感温部材と連設することで、刃物を回転させることにより、弁口部分に付着堆積したゴミや錆などの異物を削除して、弁口の詰まりを防止することができるものである。 A conventional temperature responsive valve has an inlet, a valve chamber, and an outlet formed by a valve casing, a valve port is provided between the valve chamber and the outlet, and a valve body is attached at a position facing the valve port. In addition to providing a blade to the valve body and connecting the valve body to the temperature sensing member, rotating the blade removes foreign matter such as dust and rust that has accumulated on the valve mouth and prevents clogging of the valve mouth. Is something that can be done.
上記従来の温度応動弁では、弁口部分に異物が付着堆積した場合に、刃物を回転させてその異物を削除することはできるが、操作員が刃物を回転しない限り、異物は付着したままの状態であり、異物による弁口の詰まり状態が維持されてしまう問題があった。重要な箇所に取り付けられる温度応動弁は、弁口が詰まってしまうと、温度応動弁の取り付けられた各種装置や配管、ひいてはプラント全体にも多大の悪影響を及ぼす。 In the above conventional temperature responsive valve, when foreign matter adheres and accumulates on the valve mouth, the blade can be rotated to delete the foreign matter, but the foreign matter remains attached unless the operator rotates the blade. There is a problem that the clogged state of the valve opening due to foreign matter is maintained. When the valve is clogged, the temperature responsive valve attached to an important part has a great adverse effect on various devices and piping to which the temperature responsive valve is attached, and thus on the entire plant.
解決しようとする問題点は、操作員が必要な操作を行わなくとも、弁口の詰まりの悪影響を最少限に抑えることのできる温度応動弁を得ることである。 The problem to be solved is to obtain a temperature responsive valve that can minimize the adverse effects of clogging of the valve opening, without requiring the operator to perform the necessary operations.
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口を設けて、当該弁口に対向する位置に弁体を取り付け、当該弁体を感温部材と連設して、当該感温部材の温度に応じた変形作用によって弁体が弁口を開閉弁する感温弁において、感温弁と入口を共通とする復水排出弁を並列状態で配置すると共に、復水排出弁の出口と、感温弁の出口とを別々に形成して、感温弁の出口を大気中へ開放したものである。 The present invention forms an inlet, a valve chamber, and an outlet with a valve casing, provides a valve port between the valve chamber and the outlet, attaches the valve body to a position facing the valve port, and attaches the valve body to the temperature sensing member. Condensate discharge valves that share the temperature sensing valve and the inlet are arranged in parallel in a temperature sensing valve that opens and closes the valve port by a deforming action according to the temperature of the temperature sensing member. In addition, the outlet of the condensate discharge valve and the outlet of the temperature sensing valve are formed separately, and the outlet of the temperature sensing valve is opened to the atmosphere.
本発明は、感温部材と連設した弁体と対向する位置の弁口に異物が付着して詰まってしまった場合に、並列状態に配置した復水排出弁から復水を排出することができ、操作員がなんらの操作を行うことなく、弁口の詰まりの悪影響を防止することができるという利点がある。 The present invention allows condensate to be discharged from a condensate discharge valve arranged in a parallel state when a foreign object adheres to the valve opening at a position facing the valve body connected to the temperature sensing member and becomes clogged. There is an advantage that the adverse effect of clogging of the valve opening can be prevented without any operation by the operator.
本発明は、入口を共通とする復水排出弁を配置するものであるが、復水排出弁としては、蒸気と復水の温度差に応じて開閉弁する温度応動弁に限らず、復水による浮力を利用して開閉弁するものや、蒸気と復水の熱力学的特性差に基づくいわゆるディスク式の復水排出弁など、従来周知のものを用いることができる。 The present invention arranges a condensate discharge valve having a common inlet, but the condensate discharge valve is not limited to a temperature-responsive valve that opens and closes according to the temperature difference between steam and condensate, Conventionally well-known ones such as a valve that opens and closes using buoyancy caused by the above, and a so-called disk-type condensate discharge valve based on a difference in thermodynamic characteristics between steam and condensate can be used.
図１において、弁ケーシングに形成した入口１と弁室２と出口３と、弁ケーシングの上部に配置した感温部材を内蔵した感温弁４、及び、弁ケーシングの下部に配置した復水排出弁５とで温度応動弁を構成する。 In FIG. 1, an inlet 1, a valve chamber 2, an outlet 3 formed in a valve casing, a temperature sensing valve 4 having a temperature sensing member disposed in the upper part of the valve casing, and a condensate discharge disposed in the lower part of the valve casing. The valve 5 forms a temperature responsive valve.
感温弁４には、復水排出弁５の出口３とは別に、感温弁４用出口９を接続して、その端部１０を大気中に開放する。なお、感温弁４は、従来技術と同様のもので、詳細は図示しないが、弁体に連設した感温部材や、感温弁４用の弁体や弁口を内蔵したものであり、入口１から流入してくる蒸気と復水の混合流体の温度が所定値以下に低下すると、感温部材が収縮して感温弁４用の弁口を開弁して、出口９から低温液体を大気中へ排出し、混合流体の温度が所定値以上になると、感温部材が膨張して感温弁４用の弁口を閉弁して、高温流体の大気中への排出を防止するものである。 In addition to the outlet 3 of the condensate discharge valve 5, an outlet 9 for the temperature sensitive valve 4 is connected to the temperature sensitive valve 4, and its end 10 is opened to the atmosphere. The temperature sensing valve 4 is the same as the prior art, and although not shown in detail, the temperature sensing valve 4 incorporates a temperature sensing member connected to the valve body, and a valve body and valve opening for the temperature sensing valve 4. When the temperature of the mixed fluid of steam and condensate flowing in from the inlet 1 falls below a predetermined value, the temperature sensing member contracts to open the valve port for the temperature sensing valve 4, and the temperature from the outlet 9 becomes low. When the liquid is discharged into the atmosphere and the temperature of the mixed fluid exceeds the predetermined value, the temperature sensing member expands and the valve opening for the temperature sensing valve 4 is closed to prevent the discharge of the high temperature fluid into the atmosphere. To do.
感温弁４の上端部に回転ねじ６を取り付けて、弁室２内の回転ねじ６の下端に感温弁４用の弁体を設けると共に、この弁体に対向する更に下方に、感温弁４用の弁口を配置したものである。 A rotary screw 6 is attached to the upper end portion of the temperature sensing valve 4, and a valve body for the temperature sensing valve 4 is provided at the lower end of the rotation screw 6 in the valve chamber 2. A valve port for the valve 4 is arranged.
回転ねじ６を締めこんだり、反対に、ゆるめたりすることによって、感温弁４用の弁口から排出される流体の温度を高くしたり、低くすることができるものである。 The temperature of the fluid discharged from the valve opening for the temperature sensing valve 4 can be increased or decreased by tightening the rotating screw 6 or loosening it.
復水排出弁５は、本実施例においては従来技術と同様のもので、弁室２内部に中空球状のフロートを自由状態で配置して、右側方部の弁座部材７の内部に取り付けた弁口を貫通した弁座を、中空フロートの外表面で直接に開閉弁することにより、入口１から弁室２内へ流入する蒸気と復水の混合流体の内、復水だけを出口３から外部へ排出し、蒸気は排出することのないものである。 The condensate discharge valve 5 is the same as that of the prior art in this embodiment, and a hollow spherical float is disposed in the valve chamber 2 in a free state and attached to the right side valve seat member 7. By directly opening and closing the valve seat penetrating the valve port at the outer surface of the hollow float, only the condensate of the mixed fluid of steam and condensate flowing into the valve chamber 2 from the inlet 1 is discharged from the outlet 3. It is discharged to the outside and steam is not discharged.
弁座部材７の中心部に復水排出弁５用の回転ねじ８を取り付けて、弁座部材７内部の弁座の弁口部分に付着堆積した異物を、回転ねじ８を回転することによって取り剥がすことで、弁口の詰まりを防止することができるものである。 A rotary screw 8 for the condensate discharge valve 5 is attached to the central portion of the valve seat member 7, and foreign matter adhering to the valve mouth portion of the valve seat inside the valve seat member 7 is removed by rotating the rotary screw 8. By peeling off, clogging of the valve opening can be prevented.
入口１から弁室２内へ流入した蒸気と復水の混合流体の内、復水だけが復水排出弁５の弁座部材７と出口３を通って外部へ排出される。この場合、感温弁４部には高温状態の蒸気が溜まっているために、感温弁４は閉弁を維持する。 Of the mixed fluid of steam and condensate flowing into the valve chamber 2 from the inlet 1, only condensate is discharged to the outside through the valve seat member 7 and the outlet 3 of the condensate discharge valve 5. In this case, since the high temperature steam is accumulated in the temperature sensing valve 4 part, the temperature sensing valve 4 is kept closed.
復水排出弁５の弁座部材７内の弁口が詰まってしまった場合、出口３へ復水が排出されなくなり、弁室２内に低温復水が溜まってくると、感温弁４が自動的に開弁することによって、弁室２内の復水を出口９から大気中へ排出することができる。 When the valve opening in the valve seat member 7 of the condensate discharge valve 5 is clogged, the condensate is not discharged to the outlet 3, and when the low temperature condensate accumulates in the valve chamber 2, the temperature sensing valve 4 By automatically opening the valve, the condensate in the valve chamber 2 can be discharged from the outlet 9 into the atmosphere.
出口９から大気中へ復水が排出されていることによって、感温弁４が作動していることを確認した操作員は、復水排出弁５用の回転ねじ８を回転することによって、弁座部材７内の弁口に付着堆積した異物を取り剥がして、弁口の詰まりを解消することができる。 An operator who has confirmed that the temperature sensing valve 4 is operating by discharging condensate from the outlet 9 to the atmosphere rotates the rotary screw 8 for the condensate discharge valve 5 to rotate the valve. It is possible to remove clogging of the valve port by removing the foreign matter adhering to and deposited on the valve port in the seat member 7.
粘性物質が流下する本配管を保温するために、本配管の外周に径の小さなトレースパイプを巻きつけて、トレースパイプの中に蒸気と復水の混合流体を流下させる場合に、このトレースパイプが所定温度以下とならないようにする温度応動弁として適用できる。 In order to keep the main pipe where the viscous material flows down, a trace pipe with a small diameter is wound around the outer circumference of the main pipe, and when the mixed fluid of steam and condensate flows down in the trace pipe, It can be applied as a temperature responsive valve that keeps it below a predetermined temperature.
