本考案は、液相プロパン等の圧力調整器に関
し、その異音発生を確実に防止することを目的と
する。[Detailed Description of the Invention] The present invention relates to a pressure regulator for liquid phase propane, etc., and aims to reliably prevent the generation of abnormal noise.
第１図は、従来の圧力調整器の一例を示す。そ
の概要を説明すると、減圧室１内の圧力変化に応
動するベロー型のダイヤフラム２により弁体３を
その弁棒４および弁棒押え５を介して昇降させて
ノズル部材６のノズル７を開閉して圧力調整をお
こなうようにしている。 FIG. 1 shows an example of a conventional pressure regulator. Briefly, a bellows-shaped diaphragm 2 that responds to pressure changes in the decompression chamber 1 moves the valve body 3 up and down via its valve stem 4 and valve stem retainer 5 to open and close the nozzle 7 of the nozzle member 6. The pressure is adjusted accordingly.

て摺動自在に支持されている。 Conventionally, the above-mentioned valve stem retainer 5 is fixed to the side surface of the decompression chamber of the diaphragm 2, and is extended toward the atmospheric pressure chamber 8 side, and the adjustment spring 9
It is slidably supported via an O-ring 11 by an adjustment member 10 for.

調整部材１０との間に介装したＯリング１１によ
り吸収して異音発生を防止しているものである。 These O-rings 11 are provided to prevent the pressure regulator from generating abnormal noise. In other words, the abnormal noise of a pressure regulator refers to the phenomenon in which the pressure regulator generates sound due to the vibration of the pressure receiving part, especially the valve body 3 and the valve stem 4, during high flow operation. Vibration of the valve body 3 and valve stem 4 is absorbed by an O-ring 11 interposed between a valve stem presser 5 and an adjustment member 10 that slidably supports the valve stem presser to prevent abnormal noise. It is something that exists.
しかしながら、従来は、これらＯリング１１を
前述したように大気圧室８側に設け、弁体３等の
異音発生源から遠いところで弁体等の振動を吸収
しているので、振動吸収が不十分で異音発生を確
実に防止することができなかつた。 However, in the past, these O-rings 11 were provided on the atmospheric pressure chamber 8 side as described above, and the vibrations of the valve body etc. were absorbed in a place far from the source of abnormal noise such as the valve body 3, so vibration absorption was insufficient. However, it was not possible to reliably prevent the occurrence of abnormal noise.
本考案は、このような従来の不都合を解消する
ためになされたもので、異音発生防止のためのＯ
リングを減圧室側に設けて弁体等の振動を十分に

るようにしたものである。 The present invention was made in order to eliminate such conventional inconveniences.
A ring is provided on the side of the decompression chamber to sufficiently absorb vibrations of the valve body, etc., thereby reliably preventing abnormal noise from occurring.
以下図面を参照して本考案の一実施例について
詳述する。 An embodiment of the present invention will be described in detail below with reference to the drawings.

されている。 In FIG. 2, a bellows-shaped diaphragm 22 that responds to pressure changes in the decompression chamber 21
3 and a valve stem presser 25 for raising and lowering the valve stem 24 are fixed to the side surface of the decompression chamber of the diaphragm 22 as in the conventional case.

介して摺動自在に支持されている。 According to the present invention, the valve stem retainer 25 is also slidably supported by the hollow extension 26a of the nozzle member 26 disposed on the decompression chamber 21 side via the O-ring 31.

とされている。 Note that the nozzle member 26 is connected to the valve body 23 as in the conventional case.
The adjustment member 30 for the adjustment spring 29, which is disposed on the atmospheric pressure chamber 28 side, has a nozzle 27 that can be opened and closed by the valve stem. It is said that it can be suppressed.

できる。 As described above, according to the present invention, the O-ring 31 is provided on the decompression chamber 21 side and is located close to the valve body 23 and the valve stem 24, so that the O-ring 31 is sufficiently damped from the vibrations of these valve bodies, etc. Therefore, generation of abnormal noise due to these vibrations can be reliably prevented.
