It is necessary to determine the above dimensions so that the valve will be closed when 2 becomes a predetermined pressure or more. Therefore, the pressure at the inlet 11a is set to P
Assuming that condition is 1 , the valve closing force is (π / 4) [P 1 (d 3 2 −d 1 2 ) + P 2 (d 5 2 −d 2 2 )] ≧ (π / 4) [ P 1 (d 4 2 −d 1 2 ) + P 2 (d 3 2 −d 2 2 )] + F (valve opening force) Therefore, (π / 4) [P 1 (d 3 2 −d 4 2 ) + P 2 (d 5 2 −d 3 2 )] ≧ F (1)

一定圧力以下に制限することができる。The left side of this equation is the total valve closing force due to pressure, and the right side is the valve opening force due to spring force. According to this equation, P 1 is constant and F becomes a constant force at constant elongation when the spring constant is fixed. Therefore, if d 5 is made larger than d 3 , the valve closes when P 2 becomes large. Power increases. Therefore, if the dimensions and F are defined by the relationship as shown in the above equation, when the outlet pressure P 2 exceeds a certain value, the valve closing force due to the pressure becomes larger than the spring force and the valve closes, and P 2 is further P 1 Therefore, the outlet pressure P 2 can be limited to the target constant pressure or less.

Therefore, the valve design is facilitated. Further, since the outlet pressure can be limited regardless of the inlet pressure, it is possible to prevent the backflow of the fluid to the inlet side even if the inlet pressure drops and the outlet pressure rises for some reason. Furthermore, since there are few parts related to pressure adjustment, the stability of operation is high and the outlet pressure can be reliably limited,
Improves valve reliability.

On the other hand, since d 3 and d 4 are both effective, the P 1 part of the equation (1) becomes 0, and the outlet pressure P 2 is also atmospheric pressure, the valve opening / closing force due to the pressure is almost eliminated, and the spring force F causes The valve body member 2 is surely pushed down, and the valve opens instantly. As a result, nitrogen is swiftly flown below the fire extinguishing source line 105, and the fire extinguishing section is filled up with the effect of extinguishing the fire.

グ１１ｃは用いられていない。FIG. 6 shows a structural example of another rapid opening pressure regulating valve to which the present invention is applied. This rapid opening pressure regulating valve is mainly provided in the valve body member 2 as a passage for connecting between one end side communicating with the inlet 11a of the valve body member 2 and the other end side communicating with the open pressure receiving surface 25, as compared with the valve shown in FIG. Instead of the provided conduction hole 23, a lateral conduction hole 14 and a side conduction hole 15 as passages provided in the main body 1 are provided. The space between the two conduction holes is closed by a sealing plate 52 as in the case of FIG. In this example, the sealing plate 52 is pressed and supported by the inner cylinder 62 of the valve actuating mechanism 6, and the conduction holes 14 and 15 are electrically connected by the hole 62a formed in the inner cylinder 62, and the cover 3 '. The pressure receiving surface 25 is closed at. Also, the spring receiver 3
Are screwed onto the inner surface of the body 1. The reinforcing ring 11c of FIG. 1 is not used.

点がある。Also in this example, just as in the case of FIG. 1, when the valve operating mechanism 6 is actuated and the sealing plate 52 is broken, the inlet 11 is opened.
The gas pressure of a is the horizontal conduction hole 14, the sealing plate 52, and the hole 62 in order.
The valve body member 2 can be actuated by the force of the spring 4 to instantly act on the open pressure-receiving surface 25 via the side conduction hole 15a, and the valve can be opened. When the pressure on the outlet 12a side becomes equal to or higher than the predetermined pressure when the valve is opened, the pressure on the closed pressure receiving surface 24 increases,
The valve closing force becomes greater than the valve opening force, closing the valve and preventing further pressure rise. According to the quick opening pressure regulating valve of the present example, the valve actuating mechanism 6 can be arranged in the direction perpendicular to the valve body member 2, so that there is an advantage that the overall shape of the quick opening pressure regulating valve can be miniaturized.

ことができる。As described above, the quick opening pressure regulating valve normally operates by the gas pressure from the starting gas line 104, but a failure or the like occurs in the starting system, and the working gas is fed to the valve operating mechanism 6 of the quick opening pressure regulating valve. When not supplied, the valve can be opened by direct manual operation. At this time, the sealing pin 69a is pulled out, the chain locking side of the sandwiching plate 69 is held and pulled out, and the cap 68 is pushed down to push down the operating ring 64 via the rod 67 and lower the tip 65a of the needle member. The sealing plate 52 can be broken. As a result, even if there is a failure in the starter system, nitrogen can be immediately and reliably supplied by hand, and fire extinguishing work can be performed.

It can be limited to kgf / cm 2 G or less. Therefore, the pressure resistance of all the extinguishing systems such as the piping and valves on the outlet side is the same as that of the conventional CO 2 extinguishing system of 110 kgf / cm 2
There is no need to raise it above G. As a result, for example, 150 kgf / cm 2 G without increasing equipment cost
It becomes possible to use a nitrogen fire extinguisher having a large fire extinguishing ability.

の圧力が制御される。FIG. 10 shows the relationship of the pressure applied to the valve body 2 of the quick release pressure regulating valve of FIGS. 7 and 8. FIG. 10 (a) is a view corresponding to FIG. , (B) are in a state before opening. When the sealing plate 52 is broken, in the rapid opening pressure regulating valve of this example, the gas at the inlet 11a is sequentially transferred to the lateral conduction hole 1
4, air openings 55, contact the conductive hole 16, via the upper conducting port 23 'flows into an open receiving surface 25 and the pressure receiving surface 9a of the movable spring receiver 9, the pressure P 1 on these, as shown in (a) Works. As a result, on the pressure receiving surface 9a side, the pressure P of this portion is
When the moving spring receiver 9 is pushed down by 1 and moves down to a predetermined position L while compressing the spring 4, it hits the positioning portion 17 of the middle case 10 and stops. At this time, the spring 4 compressed by the moving spring receiver 9 causes the spring force F in the opening direction to act on the valve body 2. The action of the force exerted on the open pressure receiving surface 25 by the spring force F and the pressure P 1 and the overall force relation exerted on the valve body member 2 including these are as described in FIG. 4.
Also in the valve of this example, the pressure on the outlet side is controlled by the equations (1) and (2).

When the pressure of the nitrogen cylinder 100 is high, the pressure of P 1 is high, while the valve seat 13 is in contact with the valve body 22 and the valve is closed, so the pressure on the outlet 12a side is low atmospheric pressure P 0 . . As a result, as shown in the previous equation (1), the pressure P 1
Since the valve closing force by the spring is sufficiently larger than the valve opening force F by the spring, the valve can be closed. However, when P 1 becomes a certain pressure or less, in the case of the valve of FIG. 1, the valve closing force by this becomes smaller than the valve opening force by the spring force F, and the valve opens. For example, as described above, P 1 is 150 kgf
/ According cm 2 and a P 2 to the spring force F at the time of controlling the 110 kgf / cm 2 or less of the pressure, P 1 is at maximum one-third
At about 50 kgf / cm 2 , the valve opening force by the spring force F becomes larger than the valve closing force by P 1 . And the valve will open unnecessarily.

Is released, and the moving spring receiver 9 rises from the position L where the spring force F is generated to the position H where it becomes F 0 of almost zero. As a result, the force of the spring 4 hardly acts on the spring receiving portion 26 of the valve body 2, and the closed state of the valve is maintained unless the sealing plate is broken. In addition, P 0 in the figure,

できる。According to such a quick release pressure regulating valve, it is possible to prevent the outflow of nitrogen to the outlet line even when the pressure of the nitrogen cylinder 100 drops. As shown in FIG. 5, even if the valve is opened and nitrogen enters the outlet line, in the fire extinguishing system, unnecessary extinguishing of the extinguishing gas into the extinguishing area is prevented by the main valve 107 and the selection valve 108. So there is no danger. Further, according to the valve of this example, even when the nitrogen cylinder 100 is filled with nitrogen at the time of shipment from the factory, the valve closes as soon as the pressure inside the cylinder rises due to the resistance of the valve, so that the outlet nozzle portion 12 is released. Nitrogen can be filled in the opened state or only with the cap slightly covered, and the handleability of the valve can be improved.

次のように開閉する。As described above, according to the present invention, the quick opening pressure regulating valve is provided with the main body, the valve body member, the receiving member, the urging member,
A combination of a sealing pressure means and a sealing pressure releasing means,
The valve body member or the main body is provided with a passage for connecting between one end side and the other end side of the valve body member, and one end side thereof is connected to the main body inlet and a passage to the other end side is formed by the sealing member of the sealing means. A pressure receiving area that receives the fluid pressure of the valve body part that is blocked and seated on the valve seat of the main body,
The pressure receiving area of the closed pressure receiving surface of the valve body member, the pressure receiving area of the open pressure receiving surface located on the other end side, and the opening urging force of the urging member are conducted between the one end side and the other end side of the passage to open the pressure receiving surface. When the pressure of the outlet exceeds the specified pressure while the pressure of the valve is open, the valve closing force that closes the valve body is larger than the biasing force and the valve body is closed. Since the pressure is set to be equal to or lower than the predetermined pressure, the valve body member opens and closes as follows according to each condition.

される。First, when the sealing means does not operate and the other end side is closed by the sealing member, the open pressure receiving surface does not operate and therefore the force of the inlet pressure acting on the valve member in the closing direction is applied. It becomes larger than the biasing force of the member, and the closed state of the valve body member is maintained.

確実に開くことができる。Next, when the pressure-sealing means is activated, the pressure-sealing member that seals the passage to the other end is opened, and the inlet pressure is applied to the open pressure-receiving surface, which causes the closing pressure of the valve body member inlet portion. The valve member can be surely opened by releasing or reducing it, and making the urging force of the urging member effective.

用を可能にすることができる。Further, when the outlet pressure becomes large in this state, the pressure on the closed pressure receiving surface becomes larger than the urging force of the urging member, so that the valve can be closed and the rise of the outlet pressure above a certain level can be restricted. As a result, even if the fluid inlet pressure is high, the outlet pressure can be made equal to or lower than the predetermined pressure, and the pressure resistance of the pipes and valves can be reduced to that pressure. And, for example,
Maintaining a value of 110 kgf / cm 2 G as the outlet pressure corresponding to the design pressure of the conventional fire extinguishing system, that is, 150 kgf / cm 2 without increasing the cost of the piping system and the like.
It is possible to adopt a nitrogen fire extinguisher having a high fire extinguishing ability at a high pressure of G or higher.

In addition, the sealing member can be remotely operated by the fluid pressure, and even if a failure occurs in the fluid pressure line, the sealing member can be opened and closed by manual operation on the machine side, and the safety of the device can be improved.

When the pressure is released, the pressure receiving surface receives the pressure and moves the moving receiving portion to a predetermined position in the opening direction, and the positioning portion is provided so as to stop at this position. The biasing force can be generated in the biasing member. As a result, the outlet pressure can be controlled to be equal to or lower than the predetermined pressure by the same operation as that of the first aspect of the invention.

Since the pressure receiving surface does not receive the pressure, no force is generated to move the movement receiving portion to the predetermined position, and the movement receiving portion receives the reaction force of the biasing member and freely moves in the direction opposite to the predetermined position. To do. As a result, the biasing force of the biasing member is not generated, and the valve body member is not biased in the opening direction by the biasing member. As a result, unnecessary opening of the valve due to the urging force of the urging member is prevented even when the fluid pressure on the inlet side decreases. Further, even when a gas for extinguishing a gas equipped with a quick opening pressure regulating valve is filled with the gas, the gas can be filled without completely closing the outlet side, so that the handling property of the device can be improved. it can.

It is determined by the outlet pressure, the size of the valve seat, the size of the closed pressure receiving surface, and the urging force of the urging member. Therefore, the valve can be easily designed. Further, since the outlet pressure can be limited regardless of the inlet pressure, it is possible to prevent the backflow of the fluid to the inlet side when the outlet pressure rises. Furthermore, since the portion related to the pressure adjustment is reduced, the operational stability of the valve is enhanced, the outlet pressure can be reliably limited, and the reliability of the valve can be improved.
