【考案の詳細な説明】
本案は一次流体を減圧して使用先へ供給する装置に於て
二次流体流出室と一次流体流入室の間に大小二種の弁を
設置し、二次流体の需要の少ない場合は小径弁を、又、
需要が大又は急激に増加した場合は大径弁を開くことに
より常に二次流体の供給を円滑としハンマーリングを防
止すべく案出された流体自動圧力調整装置に関す。[Detailed description of the invention] This invention is a device that reduces the pressure of the primary fluid and supplies it to the user. Two types of valves, large and small, are installed between the secondary fluid outflow chamber and the primary fluid inflow chamber. If demand is low, use small diameter valves, or
The present invention relates to an automatic fluid pressure regulating device devised to always ensure a smooth supply of secondary fluid and prevent hammering by opening a large-diameter valve when demand increases significantly or rapidly.
今、図面に就で本案装置の構成を説明すると、弁体1内
部を横の隔壁2を以て一次流体流入室Aと二次流体流出
室Bに分割し、一次流体流入室Aの上部に底部に開孔3
を備えた皿形シリンダー4を嵌着し、その中にチェック
弁5を備えたピストン6を収容し、隔壁2に穿設した大
径孔7に大径弁8を接触させると共に大径弁8に穿設し
た小径孔9に接触し且大径孔8内で軸方向に摺動可能な
小径弁10をピストンロッド11下端に取り付け、更に
外方に於てシリンダー上部と二次流体流出室Bを連結す
るバイパス管12に減圧弁13を挿入する。Now, to explain the configuration of the present device with reference to the drawings, the inside of the valve body 1 is divided into a primary fluid inflow chamber A and a secondary fluid outflow chamber B by a horizontal partition wall 2. Opening hole 3
A piston 6 equipped with a check valve 5 is fitted therein, and a large diameter valve 8 is brought into contact with a large diameter hole 7 formed in the partition wall 2. A small-diameter valve 10 that contacts the small-diameter hole 9 drilled in the hole 9 and is slidable in the axial direction within the large-diameter hole 8 is attached to the lower end of the piston rod 11, and further outwardly connects the upper part of the cylinder and the secondary fluid outflow chamber B. A pressure reducing valve 13 is inserted into the bypass pipe 12 connecting the two.
図中Pは圧力計を示す。使用に際し一次流体を流入室A
→開孔3→チェック弁5→減圧弁13へ送り、圧力計P
を見て適当に減圧した二次流体を流出室Bを経て各需要
先の配給管に充填する。In the figure, P indicates a pressure gauge. During use, the primary fluid is transferred to the inlet chamber A.
→ Opening hole 3 → Check valve 5 → Send to pressure reducing valve 13, pressure gauge P
The secondary fluid, which has been appropriately depressurized based on the above, is filled into the distribution pipes of each demand destination via the outflow chamber B.
そして需要者側で開栓して二次流体を使用するのである
が、使用量に応じピストン6上の流体が減少するのでこ
れを補うべく、流入室A内の流体は開孔3及びチェック
弁5を介しピストン6上に補給され、使用量が少なる間
はピストン6の上昇量が低いため小径弁10のみが開く
。The consumer opens the valve and uses the secondary fluid, but the fluid on the piston 6 decreases depending on the amount used, so in order to compensate for this, the fluid in the inlet chamber A is transferred to the opening 3 5 onto the piston 6, and when the amount used is low, only the small diameter valve 10 opens because the amount of rise of the piston 6 is low.
然し使用量が急に増加し或いは徐々に増加しピストン6
上の流体量が減少しピストン6の上昇が大となると小径
弁10は大径弁8を伴って上昇するので大径孔7が開き
多量の流体が流出室Bへ支給されることとなるので、本
案によると大径弁8と小径弁10の使い分けにより常に
需要量に応じ円滑に流体を支給することができハンマー
リングは起きない効果がある。However, if the amount used increases suddenly or gradually, the piston 6
When the amount of fluid above decreases and the piston 6 rises greatly, the small diameter valve 10 rises together with the large diameter valve 8, so the large diameter hole 7 opens and a large amount of fluid is supplied to the outflow chamber B. According to the present invention, by using the large-diameter valve 8 and the small-diameter valve 10 properly, fluid can be supplied smoothly according to the demand amount, and hammering does not occur.
