In the vaporizer known from Japanese Patent Application Laid-Open No. 53-117133,
When installing a member with an orifice in a conventional negative pressure introduction piping passage, etc., the orifice part is integrally formed on the nipple into which the rubber pipe for piping is inserted, or the member with an orifice is installed in the rubber pipe or other air passage. A method of inserting and fixing is known.

According to the present invention configured as described above, when connecting a rubber pipe as a piping member to a connecting nipple, the rubber pipe is inserted while pressing the member having the orifice against the tip of the connecting nipple by the insertion force of the rubber pipe. This eliminates the need for any special work for installing the orifice, and furthermore, after the rubber pipe is connected to the nipple, the member is firmly fixed to the tip of the nipple by the contraction force of the rubber pipe and will not come off.
以下本発明の実施例を第１，２図に基づき詳説

Embodiments of the present invention will be explained in detail below with reference to FIGS. 1 and 2.
通路５を形成するため配管部材（ゴムパイプ）
１２をパイプ８に挿入する作業は必らず必要であ

入、図１の如くゴムパイプ１２の弾性を利用して
オリフイス１３を固定、設置するようにしたもの
である。 Piping members (rubber pipes) to form passage 5
12 into the pipe 8 is always necessary. During this insertion work, the inner and outer diameters of the pipe 8 and the shape and dimensions of the orifice 13 are adjusted to φd 1 as shown in FIG.
The orifice 13 is inserted into the pipe 8 by configuring the relationships such as ≧φd 2 , φD 1 ≧φD 2 , and φd 1 <φD 2 , and the orifice 13 is fixed and installed using the elasticity of the rubber pipe 12 as shown in FIG. This is how it was done.
本実施例によれば、パイプ８の形状も簡単とな
り管材が利用でき、オリフイス１０の圧入作業、
穴１１のリーマ加工の廃止、またゴムパイプ１２
の弾性にさからつてオリフイス１０を圧入する作
業がいらないなど非常に安価にオリフイスを設置
することができる。一方オリフイス１３の内径を
数種準備しておけば、他の形状を統一することが
でき、共通性も高く、さらにコストダウンを図る
ことができる。 According to this embodiment, the shape of the pipe 8 is simple, and pipe material can be used.
Abolition of reaming of hole 11, and rubber pipe 12
The orifice 10 can be installed at a very low cost since there is no need to press-fit the orifice 10 against its elasticity. On the other hand, if several types of inner diameters of the orifice 13 are prepared, other shapes can be unified, commonality is high, and costs can be further reduced.
以上説明したように本発明によればオリフイス
部材を特別な取り付け作業なしに配管通路内に設
置できるという極めて実用的な効果が得られる。
As explained above, according to the present invention, an extremely practical effect can be obtained in that the orifice member can be installed in the piping passage without any special installation work.
