(イ) 産業上の利用分野
この考案は、入力あるいは出力に空気圧が使用
される工業用計測機器等で用いられる。固定絞り
に関する。[Detailed explanation of the invention] (a) Industrial application field This invention is used in industrial measuring instruments that use air pressure for input or output. Regarding fixed aperture.
(ロ) 従来の技術
一般的に、従来よりよく知られた固定絞りに
は、切削性の良い金属にドリル加工を施して穴を
開けたもの、金属細管あるいは金属細管内に焼結
金属等を含浸させたものがある。(b) Conventional technology In general, conventionally well-known fixed orifices include those made by drilling a hole in metal with good machinability, metal capillary tubes, or sintered metal etc. inside metal capillary tubes. Some are impregnated.
(ハ) 考案が解決しようとする問題点
上記した固定絞りの中、ドリル加工のものでは
穴径が最小でも0.1mmで、加工深さ0.5mmが限界と
され、さらに、それ以上の微小流量を調整するこ
とが出来なかつた。また、金属細管を使用するも
ので、微小流量を制御するとなると非常に長い距
離を必要とする問題があつた。(c) Problems that the invention aims to solve Among the above-mentioned fixed orifices, drilled ones have a minimum hole diameter of 0.1 mm and a machining depth of 0.5 mm. I couldn't adjust it. Furthermore, since the method uses a metal thin tube, there is a problem in that a very long distance is required to control a minute flow rate.
この考案は、上記に鑑み、小型で微小流量の調
整が可能な固定絞りを提供することを目的として
いる。 In view of the above, the purpose of this invention is to provide a fixed throttle that is small and capable of adjusting minute flow rates.
(ニ) 問題点を解決するための手段及び作用
この考案の固定絞りは、絶縁チユーブ内に、多
数本の金属細線よりなる縒り線を挿設するととも
に、前記絶縁チユーブ縒り線入り絶縁チユーブの
両端に継手を設けて構成されている。(d) Means and operation for solving the problem The fixed diaphragm of this invention has a stranded wire made of a large number of thin metal wires inserted into an insulating tube, and both ends of the stranded insulating tube containing the stranded wire. It is constructed by providing a joint on the.
この固定絞りは、継手が空気圧流体系の結合部
に接続されると、空気圧は多数の金属細線よりな
る縒り線のギヤツプ間を流れることになり、微小
流量の調整が可能となる。 With this fixed throttle, when the joint is connected to a joint of a pneumatic fluid system, air pressure flows between the gaps of the twisted wire made of a large number of thin metal wires, making it possible to adjust the minute flow rate.
(ホ) 実施例
以下実施例により、この考案を具体的に説明す
る。(E) Examples This invention will be specifically explained below using examples.
第１図は、この考案の一実施例を示す固定絞り

である。 FIG. 1 is an external perspective view of a fixed diaphragm showing an embodiment of this invention, and FIG. 2 is a partial sectional view of the same fixed diaphragm.
この固定絞り１は、絶縁チユーブ２と、多数本
の金属細線よりなり絶縁チユーブ２で被覆される
縒り線３と、この縒り線３入りの絶縁チユーブ２
の両端に設けられる円筒状の継手４，４とから構
成されている。 This fixed aperture 1 includes an insulating tube 2, a stranded wire 3 made of a large number of thin metal wires and covered with the insulating tube 2, and an insulating tube 2 containing the stranded wire 3.
It consists of cylindrical joints 4, 4 provided at both ends of the cylindrical joint.
縒り線３入りの絶縁チユーブ２は、専用のもの
を準備してもよいが、いわゆる電気信号の伝送に
使用するリード線を用いてもよい。この電気信号
伝送用のリード線の外覆チユーブは腐食性に優
れ、経年的にも十分な強度がある。 A dedicated insulating tube 2 containing the twisted wire 3 may be prepared, but a lead wire used for so-called electric signal transmission may also be used. The outer tube of the lead wire for electrical signal transmission has excellent corrosion resistance and has sufficient strength over time.
この実施例固定絞り１の全長は50mm、絶縁チユ
ーブ２の径が２mm程度である。 The total length of the fixed diaphragm 1 in this embodiment is 50 mm, and the diameter of the insulating tube 2 is about 2 mm.
絶縁チユーブ２の細管内に挿入された金属細線
３ａ（第３図参照）は隣接する金属細線３ａとの
間に極めて小さなギヤツプ３ｂが形成され、しか
も縒り線３であるため、その流路の長さが比較的
大となり、空気流体の絞りとしての、大なる固定
抵抗となる。 The thin metal wire 3a (see Fig. 3) inserted into the thin tube of the insulating tube 2 has an extremely small gap 3b between it and the adjacent thin metal wire 3a, and since it is a twisted wire 3, the length of the flow path is small. is relatively large, resulting in a large fixed resistance as a restriction for air fluid.
この固定絞り１を、流体系に組込む場合には、
継手４，４を流路に接続することになるが、設置
環境に応じて、絶縁チユーブ２の部分を自由に曲
げることができる。 When incorporating this fixed throttle 1 into a fluid system,
Although the joints 4, 4 are connected to the flow path, the portion of the insulating tube 2 can be bent freely depending on the installation environment.
(ヘ) 考案の効果

線入りの絶縁チユーブは柔らかいので、形状が容
易に変形するから、場所的な面での制約を受けず
に設置できるという利点がある。(f) Effects of the invention According to this invention, since an insulating tube into which twisted metal wires are inserted is used, the gap between the twisted wires is small and the flow path is long, making it possible to adjust minute flow rates. becomes. In particular, since the lead wire for electrical signal transmission can be used as a component as it is, an inexpensive fixed diaphragm can be obtained. In addition, since the insulating tube with twisted wires is soft, its shape can be easily deformed, so it has the advantage that it can be installed without being restricted by space.
