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.

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.
