The dew-point measuring adapter comprises: a tube-shaped adapter body of which one end is connected with a gas cock of gas piping and the other end is detachably connected with a detection unit of a dew-point meter having a sensor projected, and which includes a hollow part where gas flowing in from the gas cock side can contact with the sensor; and an exhaust port provided on the downstream side of the adapter body and at a position for forming a channel that allows gas flowing in the hollow part from the gas cock side to be in contact with the sensor and lets the gas discharge to the outside.

Description

本発明は、主に民生用に用いられる都市ガスやＬＰガスなどのガス用露点計に用いられる露点測定用アダプタおよびそれを用いたガス用露点計に関するものである。   The present invention relates to a dew point measuring adapter used for a gas dew point meter such as city gas or LP gas mainly used for consumer use, and a gas dew point meter using the same.

都市ガスやＬＰガスなどの主に民生用のガス管理として、ガスの露点（ガス温度と相対湿度より算出）を計測しており、その測定器として露点計が用いられており、例えば、特開２００５−２８３５０７号の鏡面冷却式露点計や特開２００７−２８５８８５号の露点計などが知られている。
しかし、従来の露点計では、工場内等の配管内を流れるガスの流路にセンサを常時セットして露点を測定するために、接続部が頻繁な取り外しを想定していないネジ機構などになっており、センサ部に残留している空気を測定用に採取したガスに置換するための排出機構も有していないため、民生用ガスの露点測定のようなスポット的な露点の測定には適していなかった。
また、センサは水分による影響が大きいため、ガス中の水分だけでなく、露点計の装置内および接続配管内の水分の微小な付着や高露点ガスの残留によって測定値が安定しないという問題点もあった。 The gas dew point (calculated from the gas temperature and relative humidity) is measured mainly for consumer gas management such as city gas and LP gas, and a dew point meter is used as the measuring instrument. A mirror-cooled dew point meter of 2005-283507 and a dew point meter of Japanese Patent Application Laid-Open No. 2007-28585 are known.
However, the conventional dew point meter has a screw mechanism, etc., where the connection part is not supposed to be removed frequently because the dew point is measured by always setting the sensor in the gas flow path flowing in the piping such as the factory. It is suitable for spot dew point measurement, such as measuring the dew point of consumer gas, because it does not have a discharge mechanism to replace the air remaining in the sensor with the gas collected for measurement. It wasn't.
In addition, because the sensor is greatly affected by moisture, not only the moisture in the gas, but also the problem that the measured value is not stable due to the minute adhesion of moisture in the dew point meter device and the connection piping and the residual high dew point gas. there were.

請求項４の発明では、請求項１から３のいずれかに記載の露点測定用アダプタを有することを特徴とするガス用露点計であることを特徴とする。 In order to solve the above problems, the invention of claim 1
A dew point measuring adapter that discharges air and atmosphere in the measurement chamber with the flowing gas and measures the dew point of the gas with a sensor for dew point measurement,
A tubular pipe having one end connected to a gas plug of a gas pipe, the other end detachably connected to a detection unit of a dew point meter with a sensor protruding, and a gas flowing from the gas plug side capable of contacting the sensor Adapter body,
A discharge port provided at a position on the downstream side of the adapter main body to form a flow path for contacting the gas flowing into the hollow portion from the gas plug side with the sensor and discharging the gas to the outside of the adapter main body. And
In the invention of claim 2,
One end of the adapter body is provided with a quick coupling socket that can be connected to the gas plug with a single touch, and a flow rate adjusting valve is formed at the discharge port.

The invention of claim 4 is a gas dew point meter comprising the dew point measuring adapter according to any one of claims 1 to 3.

本発明のガス露点計は、配管に設けられたガス栓に接続してそのまま露点の測定を行うことができる。
露点測定用アダプタには、センサの近くに排出口部を設け、該排出口部は流量調整弁を有しているので、アダプタ内の空間に残留するガスや雰囲気を置換することができ、アダプタは筒型で小容量なので、上記置換を短時間で行うことができる。
また、排出口部に流量調整弁を設けることで排出量を調整でき、様々な露点計で定められている測定流量にも対応することができる。また、流量調整弁は全開状態であってもガス栓側のプラグのヒューズ機構が作動しないように流量が調整されていることが好ましい。
ガス栓との接続には、迅速継手を用いることで、ガス栓側のプラグとアダプタ側のソケットとをワンタッチで着脱することができ、ガス栓と容易にアダプタを接続することが可能である。
前記アダプタは、筒体で容量が小さいので、内部への水分付着が少ないため、測定への影響が小さく、また高露点ガスを測定した後でも連続して安定した露点の測定が可能である。
また、排出されるガスの付臭成分は活性炭ユニットなどの脱臭装置によって吸着させることで無臭化することができる。 The gas dew point meter of the present invention can be connected to a gas stopper provided in a pipe and measure the dew point as it is.
The adapter for dew point measurement is provided with a discharge port near the sensor, and the discharge port has a flow adjustment valve, so that the gas and atmosphere remaining in the space in the adapter can be replaced. Since the cylinder has a small capacity, the above replacement can be performed in a short time.
In addition, the discharge amount can be adjusted by providing a flow rate adjusting valve at the discharge port, and the measurement flow rate determined by various dew point meters can be handled. Moreover, it is preferable that the flow rate is adjusted so that the fuse mechanism of the plug on the gas plug side does not operate even when the flow rate adjusting valve is fully opened.
By using a quick coupling for connection to the gas stopper, the plug on the gas stopper side and the socket on the adapter side can be attached and detached with one touch, and the adapter can be easily connected to the gas stopper.
Since the adapter has a cylindrical body and has a small capacity, moisture adhesion to the inside is small. Therefore, the influence on the measurement is small, and a stable dew point can be measured continuously even after high dew point gas is measured.
Further, the odorous component of the discharged gas can be made non-brominated by being adsorbed by a deodorizing device such as an activated carbon unit.

一端がガス配管のガス栓に接続され、他端がセンサを突出させた露点計の露点測定部に接続される管状のアダプタ本体と、該アダプタ本体の下流側でセンサ近傍に設けられてガス栓側から流入したガスをアダプタ本体の外部へ排出させる排出口とを設けたことを特徴とする。   A tubular adapter body connected at one end to the gas plug of the gas pipe and at the other end to the dew point measuring part of the dew point meter with the sensor protruding, and a gas plug provided near the sensor on the downstream side of the adapter body And a discharge port for discharging the gas flowing in from the side to the outside of the adapter body.

図１および図２に示す露点測定用アダプタ１は、測定対象となる配管（図示せず）からガス栓１０を介して流入したガスを、露点測定用のセンサＳに接触させ排出口部５から排出させる流路を形成した露点測定用アダプタである。
ここで、上記センサＳは、公知の露点計の露点測定用のセンサであって、露点測定部２０の筐体上に突出した形状からなっている。 The dew point measuring adapter 1 shown in FIG. 1 and FIG. 2 is configured so that the gas flowing in through a gas plug 10 from a pipe (not shown) to be measured is brought into contact with the sensor S for dew point measurement and is discharged from the outlet 5. It is a dew point measuring adapter having a flow path to be discharged.
Here, the sensor S is a sensor for measuring a dew point of a known dew point meter, and has a shape protruding on the housing of the dew point measuring unit 20.

上記センサＳの構造や、露点の測定方式については公知の構造や方式であればよく、この発明では特に限定されない。
なお、露点計に形成される露点測定部２０は、センサＳより下方にガスを流入させる空間を設けてはおらず、本実施例ではセンサＳの下部は塞がっている。 The structure of the sensor S and the dew point measurement method may be any known structure and method, and are not particularly limited in the present invention.
In addition, the dew point measurement part 20 formed in a dew point meter does not provide the space into which gas flows in below the sensor S, and the lower part of the sensor S is closed in the present Example.

次に、露点測定用アダプタ１は、管状のアダプタ本体２と、該アダプタ本体２の一端側に連結されて配管のガス栓１０に設けられたプラグ１１に対応しワンタッチで接続されるソケット状の迅速継手３と、アダプタ本体２の他端側に形成されて露点計のセンサＳが設けられた露点測定部２０に連結される連結部４と、該アダプタ本体２の他端側で外向きに設けられた排出口部５とから構成されている。
本実施例では、アダプタ本体２は、迅速継手３を先端に連結した可撓性を有するガス用のゴム管を用いているが、管であればよい。 Next, the dew point measuring adapter 1 is a socket-shaped adapter body 2 that is connected to one end side of the adapter body 2 and is connected to the plug 11 provided on the gas plug 10 of the pipe with a one-touch connection. A quick coupling 3, a connecting part 4 formed on the other end side of the adapter body 2 and connected to a dew point measuring part 20 provided with a sensor S of a dew point meter, and outwardly on the other end side of the adapter body 2 It comprises a discharge port portion 5 provided.
In the present embodiment, the adapter main body 2 uses a flexible rubber tube for gas having a quick joint 3 connected to the tip, but may be any tube.

連結部４はＴ字状の継手（チーズ）のような形状からなっており、中央にセンサＳを収納して上下に貫通する中空を備えた収納部４１を有している（図３参照）。
該収納部４１の上部には、該収納部４１の中空と連通する中空を備え、前記ガス用の管からなるアダプタ本体２の他端と接続して、アダプタ本体２に流入したガスを収納部４１の中空内に導入する導入口部４２が形成されている。 The connecting portion 4 has a shape like a T-shaped joint (cheese), and has a storage portion 41 having a hollow that penetrates the sensor S at the center and penetrates up and down (see FIG. 3). .
The upper portion of the storage portion 41 is provided with a hollow communicating with the hollow of the storage portion 41, and is connected to the other end of the adapter main body 2 formed of the gas pipe so that the gas flowing into the adapter main body 2 is stored in the storage portion. An inlet port 42 is formed for introduction into the hollow of 41.

該収納部４１の側部には、収納部４１の中空と連通する中空を備え、収納部４１の中空内に導入されたガスをアダプタ本体２の外部へ排出する排気口部５が形成されている。   A side portion of the storage portion 41 is provided with a hollow communicating with the hollow of the storage portion 41, and an exhaust port portion 5 for discharging the gas introduced into the hollow of the storage portion 41 to the outside of the adapter body 2 is formed. Yes.

前記収納部４１の下部には、前記センサＳが設けられた露点測定部２０に連結するための露点計連結部４４が設けられている。
本実施例では、前記露点計連結部４４は、露点測定部２０の外周に刻設されたネジ部に螺合するネジ部が内周に刻設された筒部からなっており、露点測定部２０のネジに螺合して連結され、露点測定部２０によって露点計連結部４４の底面が閉塞されている。 A dew point meter connecting portion 44 for connecting to the dew point measuring portion 20 provided with the sensor S is provided below the storage portion 41.
In the present embodiment, the dew point meter connecting portion 44 is composed of a cylindrical portion in which a screw portion screwed into a screw portion engraved on the outer periphery of the dew point measuring portion 20 is engraved on the inner periphery, and the dew point measuring portion The dew point measuring unit 20 closes the bottom surface of the dew point meter connecting unit 44.

この実施例では、前記露点計連結部４４は露点測定部２０に気密的に連結することができればよく、螺合に限らず係合や掛止構造など公知構造を用いることができる。
従って、連結部４は、アダプタ本体２に流入したガスをセンサＳが配置される収納部４１の中空内に導入し、排出口部５から排出させるエルボ状の流路機能を有している。 In this embodiment, it is sufficient that the dew point meter connecting portion 44 can be airtightly connected to the dew point measuring portion 20, and not only screwing but also a known structure such as an engagement or a latching structure can be used.
Therefore, the connecting part 4 has an elbow-like flow path function that introduces the gas flowing into the adapter body 2 into the hollow of the storage part 41 in which the sensor S is arranged and discharges it from the discharge port part 5.

また、排出口部５には、排出量を調整するための流量調整弁６およびその操作レバーが設けられている。
流量調整弁６を設けることで排出量を調整できるので、様々な露点計で定められている測定流量に調整することができ、露点測定用アダプタ１を各種の露点計に対応させて取付けることができる。
本実施例で、上記流量調整弁６は、全開状態であってもガス栓側のプラグのヒューズ機構が作動しないように流量が調整される。
上記排出口部５は、後述の脱臭装置７（例えば活性炭ユニットなど）に接続して、脱臭して無臭化したガスを外気に放出してもよい。
あるいは、排出口部５に、長尺のゴム管を接続し、該ゴム管を経由して離間した安全な場所に、ガスを放出してもよい。 Further, the discharge port portion 5 is provided with a flow rate adjusting valve 6 for adjusting the discharge amount and its operation lever.
Since the discharge amount can be adjusted by providing the flow rate adjusting valve 6, it can be adjusted to the measurement flow rate determined by various dew point meters, and the dew point measuring adapter 1 can be attached corresponding to various dew point meters. it can.
In the present embodiment, the flow rate of the flow rate adjusting valve 6 is adjusted so that the fuse mechanism of the plug on the gas plug side does not operate even in the fully opened state.
The discharge port 5 may be connected to a deodorizing device 7 (for example, an activated carbon unit or the like), which will be described later, to release deodorized and non-brominated gas to the outside air.
Alternatively, a long rubber tube may be connected to the discharge port portion 5, and the gas may be discharged to a safe place separated via the rubber tube.

これによりガス栓１０のプラグ１１に、前記迅速継手３をワンタッチで接続し、ガス栓１０を開くと、配管内のガスがアダプタ本体２の内部に流入される。
流入したガスは、アダプタ本体２を通り、連結部４の中空を通って排出口部５まで続く流路Ｆを通って、排出される。 As a result, when the quick joint 3 is connected to the plug 11 of the gas plug 10 with one touch and the gas plug 10 is opened, the gas in the pipe flows into the adapter body 2.
The gas that has flowed in passes through the adapter main body 2, passes through the hollow of the connecting portion 4, passes through the flow path F that continues to the discharge port portion 5, and is discharged.

ここで、アダプタ本体２は管状からなっており、センサＳとの距離も長くする必要はないので、前記流路Ｆを比較的短く形成することができ、測定前にアダプタ本体２や連結部４の中空内に留まっている空気や雰囲気は、ガスの流入により排出され、流入したガスによって迅速に置き替えることができ、センサＳによる露点の計測を速やかに行うことができ、サンプリングするガスの量も少量ですむ。
また、ガス栓から導入したガスの放出は、無臭化したり、測定場所と離れた安全な場所に排出することもできる。 Here, since the adapter main body 2 is formed in a tubular shape and it is not necessary to increase the distance from the sensor S, the flow path F can be formed relatively short, and the adapter main body 2 and the connecting portion 4 can be formed before measurement. The air or atmosphere remaining in the hollow of the gas is exhausted by the inflow of gas, can be quickly replaced by the inflowed gas, can quickly measure the dew point by the sensor S, and the amount of gas to be sampled Even a small amount is enough.
Moreover, the release of the gas introduced from the gas stopper can be made non-brominated or discharged to a safe place away from the measurement place.

図４に示す実施例２の露点測定用アダプタ１は、迅速継手３を省略し、アダプタ本体２となるガス用の可撓性を有する管を直接にガス栓１０に接続した構成からなっている。
図中、２１は露点測定部２０を有する露点計の概略を示すが、特にこの発明の露点計の形状や構成を限定するものではない。
この実施例では、迅速継手３を利用しないためガス栓１０との着脱の点で前記実施例とは異なるが、その他の構成は同様であるので、この場合も本発明の範囲に含まれる。 The dew point measurement adapter 1 of Example 2 shown in FIG. 4 has a configuration in which the quick joint 3 is omitted and a flexible tube for gas that becomes the adapter body 2 is directly connected to the gas plug 10. .
In the figure, reference numeral 21 denotes an outline of a dew point meter having the dew point measuring unit 20, but the shape and configuration of the dew point meter of the present invention are not particularly limited.
In this embodiment, since the quick joint 3 is not used, it differs from the above embodiment in terms of attachment and detachment with the gas stopper 10, but other configurations are the same, and this case is also included in the scope of the present invention.

図５に示す実施例３の露点測定用アダプタ１および露点計２１は、アダプタ本体２をガス用の管に替えて、樹脂製または金属製の筒体を用いた構成からなっている。
このアダプタ本体２には、実施例１と同様に先端に迅速継手３が取り付けられている。
また、アダプタ本体２の下部は連結部４となっており、その下端で略同径の筒体からなる露点測定部２０の上端とネジにより螺合している。 The dew point measuring adapter 1 and the dew point meter 21 of Example 3 shown in FIG. 5 have a configuration using a resin or metal cylinder instead of the adapter main body 2 with a gas pipe.
The adapter body 2 is provided with a quick joint 3 at the tip as in the first embodiment.
Moreover, the lower part of the adapter main body 2 is the connection part 4, and is screwing together with the upper end of the dew point measurement part 20 which consists of a cylindrical body of substantially the same diameter at the lower end.

また、アダプタ本体２の下方はエルボー状に形成されて外方へ突出する排出口部５が形成されている。
なお、図中、符号６は流量調整弁６の操作レバー、７は脱臭装置である。 Further, a discharge port portion 5 that is formed in an elbow shape and protrudes outward is formed below the adapter body 2.
In the figure, reference numeral 6 denotes an operation lever of the flow rate adjusting valve 6, and 7 denotes a deodorizing device.

本実施例では、前記実施例と同様に迅速継手３をガス栓１０のプラグ１１に接続し、ガス栓１０を開いて、ガスをアダプタ本体２内に導入する。
アダプタ本体２の下流側に排出口部５が設けられているので、迅速継手３を介してアダプタ本体２内に導入されたガスは、該アダプタ本体２の下流側で前記排出口部５より僅かに上流側ないしは同一レベルに配置されたセンサＳを経由して排出口部５へと流れて行く。 In the present embodiment, the quick joint 3 is connected to the plug 11 of the gas plug 10 as in the above embodiment, the gas plug 10 is opened, and the gas is introduced into the adapter body 2.
Since the discharge port 5 is provided on the downstream side of the adapter main body 2, the gas introduced into the adapter main body 2 through the quick joint 3 is slightly less than the discharge port 5 on the downstream side of the adapter main body 2. Then, it flows to the discharge port 5 via the sensor S arranged upstream or at the same level.

また、前記センサＳで検知された検知信号は、携帯型の露点計によって演算され露点の数値を表示することができる。
これにより、本実施例でも前記実施例と同様に、簡単かつ正確に配管内のガスの露点を測定することができる。 The detection signal detected by the sensor S can be calculated by a portable dew point meter to display the dew point value.
Thereby, also in the present embodiment, the dew point of the gas in the pipe can be measured easily and accurately as in the above embodiment.

上記実施例では、アダプタ本体の下端に連結部を設けて、露点計の露点測定部と着脱可能に連結した構成を示したが、アダプタ本体は露点測定部と一体に形成されるものでもよい。
要するに、アダプタ本体内に、流入したガスがセンサと接触してから排出口部へ流れる流路Ｆが形成されればよい。 In the above-described embodiment, a configuration in which a connecting portion is provided at the lower end of the adapter main body and is detachably connected to the dew point measuring portion of the dew point meter is shown, but the adapter main body may be formed integrally with the dew point measuring portion.
In short, it is only necessary to form a flow path F that flows to the discharge port after the gas that has flowed in contact with the sensor in the adapter body.

また、上記実施例で露点を測定する対象となるガスは、都市ガスでもＬＰガスであってもよい。
また、上記ガスは民生用に用いるガスに限定されず、産業用に用いるものであってもよく、配管中にガス栓を有するものであればよい。
その他、この発明は上記実施例に限定されるものではなく、要するにこの発明の要旨を変更しない範囲で種々設計変更しうるものである。 In addition, the gas whose dew point is measured in the above embodiment may be city gas or LP gas.
Moreover, the said gas is not limited to the gas used for civilian use, Industrial use may be used, and what is necessary is just to have a gas stopper in piping.
In addition, the present invention is not limited to the above-described embodiments, and various design changes can be made without departing from the scope of the present invention.
