【考案の詳細な説明】
本考案は、血圧計などに用いる簡易圧力制御弁
に関するものである。[Detailed Description of the Invention] The present invention relates to a simple pressure control valve used in blood pressure monitors and the like.
例えば、空気配管内の圧力が設定値以上になる
と、内部空気を放出して圧力を設定値以下に保つ
ものとして圧力制御弁（リリーフバルブ）があ
る。 For example, there is a pressure control valve (relief valve) that releases internal air when the pressure in an air pipe exceeds a set value to keep the pressure below the set value.
この種の圧力制御弁は、一般に第１図、第２図
に示すように空気配管との接続口１と空気排出口
２の間に弁３を設け、圧力をこの弁３に連結した
ダイアフム４で受けるか（第１図）、弁３に直接
受け（第２図）、その圧力がスプリング５の力に
打ち勝つたとき弁３が開く構造になつている。 This type of pressure control valve generally includes a valve 3 between a connection port 1 to an air pipe and an air discharge port 2, as shown in FIGS. 1 and 2, and a diaphragm 4 connected to the valve 3. The pressure is received by the valve 3 (Fig. 1) or directly by the valve 3 (Fig. 2), and when the pressure overcomes the force of the spring 5, the valve 3 opens.
つまり、空気配管内の圧力がスプリング５の力
より大きくなれば弁３は開き、空気配管内の空気
がスプリング５の力と同じになるまで排出される
ことによつて、空気配管の圧力制御が行われる。
この場合、設定圧力はスプリング５の調整により
変更可能である。 In other words, when the pressure inside the air piping becomes greater than the force of the spring 5, the valve 3 opens and the air inside the air piping is discharged until the force becomes equal to the force of the spring 5, thereby controlling the pressure of the air piping. It will be done.
In this case, the set pressure can be changed by adjusting the spring 5.
しかし、このような構造では、小形化・軽量化
が難しく、１Kg／cm2以下の圧力を制御する血圧計
などに用いた場合には全体的に大形となる。ま
た、各部品に高い加工精度を要求され、高価とな
るといつた問題点がある。 However, with such a structure, it is difficult to reduce the size and weight, and when used in a blood pressure monitor that controls a pressure of 1 kg/cm 2 or less, the overall size becomes large. In addition, each part requires high processing precision, making it expensive.
本考案は上記事情に鑑みてなされたもので、小
形化・軽量化が図れる簡易圧力制御弁を提供する
ことを目的とする。 The present invention was devised in view of the above circumstances, and an object of the present invention is to provide a simple pressure control valve that can be made smaller and lighter.
本考案に係る簡易圧力制御弁は、一端を閉じ、
他端の開口を空気配管などとの接続口とする管体
の側面に排気孔を設け、この管体に排気孔を覆う
如くラバーチユーブを密着させ、その規制位置に
よつて圧力設定を行うようにしている。 The simple pressure control valve according to the present invention has one end closed,
An exhaust hole is provided on the side of the tube, with the opening at the other end serving as a connection port for air piping, etc., and a rubber tube is tightly attached to the tube so as to cover the exhaust hole, and the pressure is set by the regulating position of the tube. I have to.
以下、本考案を図示の実施例に基づいて詳細に
説明する。 Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

１Ｂを覆う如く管体１１に密着させたラバーチユ
ーブ１４の位置規制を行つている。 Figures 3 to 6 show an embodiment of the present invention, in which an opening at the other end of a tube body 11 with one end closed is used as a connection port 11A for connecting to an air pipe, etc., and an exhaust hole 11B is formed on the side surface. are doing. Threaded portions 11C and 11C' are formed on both sides of the exhaust hole 11B in the axial direction, and nuts 12 and 13 are screwed into the screw portions 11C and 11C'.
The position of the rubber tube 14, which is brought into close contact with the tube body 11 so as to cover the tube 1B, is regulated.
例えば、圧力設定値を最大とする場合には第３
図のように排気孔１１Ｂの中心にラバーチユーブ
１４の中心が一致する位置とし、設定値を下げる
にはラバーチユーブ１４の位置をずらせて排気孔
１１Ｂの中心とチユーブ１４の端縁の間の距離を
第３図の場合のl1より短いl2とする。 For example, if the pressure setting value is to be the maximum, the third
As shown in the figure, the center of the rubber tube 14 is aligned with the center of the exhaust hole 11B, and to lower the set value, the position of the rubber tube 14 is shifted so that the distance between the center of the exhaust hole 11B and the edge of the tube 14 is Let l 2 be shorter than l 1 in the case of Fig. 3.

ラバーチユーブ１４が変形し、隙間から内部空気
設定値以下になるまで放出される。 With such a configuration, when the internal pressure of the air piping becomes higher than the set value determined according to the elastic force of the rubber tube 14 and the regulation position, the rubber tube 14 deforms as shown in FIG. 6, and the internal air setting is removed from the gap. will be emitted until the value falls below the value.
この圧力制御弁は１Kg／cm2程度以下の比較的低
圧の圧力制御に適している。 This pressure control valve is suitable for relatively low pressure control of about 1 kg/cm 2 or less.
なお、ラバーチユーブ１４の位置規制は、ナツ
