Abstract

PROBLEM TO BE SOLVED: To provide a solenoid valve preventing drain from occurring even in a case of not using low-dew-point air accompanied with energy consumption, and also having no new energy consumption.SOLUTION: Since compressed air is fed to an air inlet of a solenoid valve 1 assembled with a moisture separation film module 2, air pressure is always kept to high pressure, and the outside of a moisture separation film 3 is connected to an air outlet, atmospheric pressure is opened. Every time the solenoid valve 1 is changed over, since exhausted air from an air cylinder 4 flows outside the moisture separation film 3 at low pressure, and compressed air flows in the hollow of the moisture separation film 3, moisture permeation from the compressed air to the exhausted air occurs through the moisture separation film 3, and then dried air is fed to the air cylinder 4. Since the solenoid valve 1 has a moisture separation film type air dryer function using the exhausted air for dehumidification purge, a drive circuit of the air cylinder 4 can be constructed, the drive circuit dispensing with low-dew-point air accompanied with large amount of energy consumption and having no new energy consumption at all.SELECTED DRAWING: Figure 1

Description

本発明は、エアーシリンダー駆動用の電磁弁に関する。  The present invention relates to an electromagnetic valve for driving an air cylinder.

圧縮エアーでエアーシリンダーを駆動する際に、排気側では圧縮エアーの断熱膨張による温度低下が起こり、圧縮エアー中の水分が結露してドレン化する。  When the air cylinder is driven by compressed air, a temperature drop occurs due to adiabatic expansion of the compressed air on the exhaust side, and moisture in the compressed air is condensed and drained.

この発生ドレンによるエアーシリンダーや電磁弁の作動不良を防止するため、駆動エアー源にエアードライヤーを設置して供給するライン構成が一般的であるが、エアードライヤーでの多大なエネルギー消費が問題となる。  In order to prevent malfunction of the air cylinder and solenoid valve due to this generated drain, a line configuration in which an air dryer is installed and supplied to the drive air source is common, but enormous energy consumption in the air dryer becomes a problem. .

そこで本発明では、エネルギー消費を伴う低露点エアーでなくてもドレン発生が起こらず、且つ新たなエネルギー消費も必要のない電磁弁を提供することを課題とする。  Accordingly, an object of the present invention is to provide a solenoid valve that does not generate drainage and does not require new energy consumption even if it is not low dew point air that involves energy consumption.

課題の解決のための本発明は、圧縮エアー給気流路に水分分離膜モジュール２を組み込んだ構造を特徴とする電磁弁１である。  The present invention for solving the problem is an electromagnetic valve 1 characterized by a structure in which a moisture separation membrane module 2 is incorporated in a compressed air supply passage.

電磁弁１の給気口には圧縮エアーが送られエアー圧力は常に高圧下に保たれ、水分分離膜３の外側は排気口に接続されているので大気圧開放状態となる。  Compressed air is sent to the air supply port of the solenoid valve 1 so that the air pressure is always kept at a high pressure. Since the outside of the moisture separation membrane 3 is connected to the exhaust port, the atmospheric pressure is released.

電磁弁１が切り替わるたびに、エアーシリンダー４からの排気エアーが水分分離膜３の外側を低圧で流れ、水分分離膜３の中空内を圧縮エアーが流れるので、圧縮エアーから排気エアーへ水分分離膜３を通じて水分の透過が起こりエアーシリンダー４にドライエアーが送られる。  Every time the solenoid valve 1 is switched, the exhaust air from the air cylinder 4 flows outside the moisture separation membrane 3 at a low pressure, and the compressed air flows inside the hollow of the moisture separation membrane 3, so that the moisture separation membrane from the compressed air to the exhaust air. Through 3, moisture permeates and dry air is sent to the air cylinder 4.

上記のように、電磁弁１自体が排気エアーを除湿パージに利用する水分分離膜式エアードラーヤー機能を持つため、多大なエネルギーの消費を伴う低露点エアーを必要とせず、且つ新たなエネルギー消費を全く伴わないエアーシリンダー４の駆動回路が構築できる。  As described above, the solenoid valve 1 itself has a moisture separation membrane type air dryer function that uses exhaust air for dehumidification purge, so it does not require low dew point air that consumes a large amount of energy, and new energy consumption. It is possible to construct a drive circuit for the air cylinder 4 that is not accompanied at all.

以下、本発明の実施の形態を図１に基づいて説明する。  Hereinafter, an embodiment of the present invention will be described with reference to FIG.

電磁弁１の給気ポートに、水分分離膜モジュール２を組み込むだけの簡単な構造である。  This is a simple structure in which the moisture separation membrane module 2 is incorporated into the air supply port of the electromagnetic valve 1.

エアーシリンダー４が動作する場合は必ず、エアーシリンダー４からの排気が起こるがその排気エアーが水分分離膜３の外側を流れるようにする。
電磁弁が切り替ると圧縮エアーは水分分離膜３の中空内を通ってエアーシリンダー４へ流れる。When the air cylinder 4 is operated, exhaust from the air cylinder 4 occurs, but the exhaust air is allowed to flow outside the moisture separation membrane 3.
When the solenoid valve is switched, the compressed air flows into the air cylinder 4 through the inside of the moisture separation membrane 3.

このとき、水分分離膜３の外側にはエアーシリンダー４からの排気エアーが低圧で流れるので、水蒸気圧の高い圧縮エアーから水蒸気圧の低い排気エアーへ水分分離膜３を通じた水分透過がおこる。  At this time, since the exhaust air from the air cylinder 4 flows at a low pressure outside the moisture separation membrane 3, moisture permeation through the moisture separation membrane 3 occurs from the compressed air having a high water vapor pressure to the exhaust air having a low water vapor pressure.

この除湿作用の結果、エアーシリンダー４へ送られる圧縮エアーは常にドライエアーとなり、次の排気時に断熱膨張による温度低下が起こっても水分の結露は起こらないので、結露ドレンによる作動不良の無いエアーシリンダーの駆動回路が構築でき、且つ新たなエネルギーの消費も必要としない。  As a result of this dehumidifying action, the compressed air sent to the air cylinder 4 is always dry air, and no moisture condensation occurs even if the temperature drops due to adiabatic expansion during the next exhaust, so there is no malfunction due to condensation drainage. The drive circuit can be constructed, and new energy consumption is not required.
