The present invention relates to a valve actuating device for a fire extinguishing system, and in particular, the spindle type fire extinguisher valve can be quickly opened without the need for a separate starting container to effectively perform super fire fighting, and the configuration of the device is simple, thereby reducing the manufacturing cost according to manufacturing. A valve actuating device for fire extinguishing equipment can be reduced.

In general, the fire extinguisher is used to extinguish the fire extinguisher by discharging the extinguishing liquid charged in the cylinder to the outside through the operation valve and the injection nozzle.

An example of the operation structure of the fire extinguisher is shown in detail in the prior art of the Republic of Korea Utility Model No. 20-0253395, the configuration of the valve operation device of the conventional fire extinguisher, as shown in Figure 1a and 1b, A cylinder 20 into which the extinguishing liquid is charged is formed, and a body 1 for discharging the extinguishing liquid into the injection hose is formed by the operation levers 10 and 11 at the upper end of the cylinder 20.

A part of the spindle 4 is coupled to the coupling hole 1d formed in the transverse direction inside the body 1, and a support plug is screwed to the other end of the spindle 4, and the coupling hole 1d On one side of the communicating guide hole 1h, the injection hole 1e is formed in a right angle direction.

In addition, one end of the support plug is elastically supported by the coil spring 7, and the seat packing 2 coupled to the other side is pressed against the body seat to prevent the extinguishing fluid from leaking to the outside without operating the operating lever. It is formed to.

On the other hand, the coil spring (7) is installed in the space formed in communication with the coupling hole (1d), the rear end of the coil spring (7) copper plate and safety plug for supporting the packing (8) and the coil spring (7) 6 is sequentially coupled to the fastening hole.

The actuator consisting of the spindle 4, the support plug 3 and the seat packing 2 is configured to open the digestive fluid transfer path by the operation levers 10 and 11.

The operation of the valve for the fire extinguisher according to the related art configured as described above rotates the operation lever 10 downward with respect to the lever engagement hole 12a and the spindle by the push tip 10a formed at the bottom of the operation lever 10. 4) will move backwards.

At the same time, the support plug elastically supported by the coil spring 7 is pushed backwards, thus opening between the seat packing and the body seat.

Therefore, the extinguishing liquid charged into the cylinder passes through the outlet hole 1a of the body 1 and the space part by the pressure difference between the cylinder and the cylinder outside, and then the coupling hole 1h and the injection hole 1e. And sprayed through the injection hose 40 in sequence to the outside.

However, in the conventional fire extinguisher valve as described above, the user directly grasps and presses the operation lever 10 of the fire extinguisher valve in the event of a fire, and thus requires a lot of force to operate the operation lever. There was a problem that can not be easily operated.

On the other hand, in order to overcome the above closed, Utility Model Publication No. 1986-000339 (November 27, 1986) discloses the opening of the valve of the cylinder container by the operation of the solenoid needle assembly according to the sensing action or manual operation of the known sensor when a fire occurs. By doing so, there is proposed a package type automatic fire extinguishing device that enables efficient global or local evolution of a protected object.

That is, the conventional package type automatic fire extinguishing device forms a solenoid needle assembly casing having a compartment separated up and down by an intermediate partition wall, and an electrical signal input through a control circuit of the control panel on one side of the lower compartment. An electromagnet operated according to the present invention was provided with an inclined contact surface formed to be inclined at a predetermined angle on the upper end portion of the core, which penetrated to one side of the electromagnet, and in the upper compartment, the needle was outgoing through one side wall of the compartment. The pin is installed at one end of the working rod of a certain length so that it can be moved forward and backward along the longitudinal direction of the compartment so that it is elastically installed with a compression spring, but on one side of the middle partition wall, the upper and lower compartments The through hole penetrating in the vertical direction, and the through hole has a tip end of the electromagnet core. A sliding roller in contact with the side or its inclined contact surface is inserted into the lower end thereof so that the upper side of the lifting pin bonded to the shaft pin can be freely flowed up and down, while being annular to the upper end of the lifting pin and the inner peripheral wall of the rear end of the operating rod. One steel bowl is interposed between the recessed grooves, and another guide roller adhering to the roller fixing piece fixed to one side of the lower compartment is supported by the lower end of the electromagnet core, while One side wall is configured to inject the operation of the push button for manual operation inward so that the tip is in contact with the tip of the electromagnet core supported by the up and down rollers, so that the solenoid needle assembly thus constructed is By connecting to one side, the needle pin of the operating rod, which is directed to one side of the casing, moves inside the valve body. It is positioned at a certain distance from the disk-shaped sealing film installed on the rear side of the side. In the normal state before the solenoid assembly is operated, the sliding roller at the bottom of the lifting pin installed in the through hole of the intermediate bulkhead is the upper side of the electromagnet core. It is a state in which the supporting force is supported on the horizontal supporting surface, which is the inner side of the inclined contact surface, and the steel bowl placed on the upper end of the lifting pin is interposed between the stop grooves at the rear end of the operating rod, and the forward force of the operating rod elastically installed by the compression spring is suppressed. In such a state, when the core is pulled by the return spring according to the electrical signal applied to the electromagnet as described above, the upper part of the core in contact with the sliding roller of the lifting pin is released from it, and the sliding roller moves the inclined contact surface of the core. It descends along and is supported by the tip, and at the same time the lifting pin and steel bowl As it descends together by a regular distance to release the stopping force of the stop groove of the operating rod, the resilient elasticity of the compression spring advances the operating rod, causing the needle pin of the tip to burst the valve of the valve. The gas pressure charged between the rear and the gas passage drops and at the same time, the movable gas valve is reversed by the pressure of the compressed gas inside the gas container to open the closed gas passage, thereby opening the closed gas passage. The release of the gas is initiated. On the other hand, when the fire is first confirmed by the naked eye, if you want to manually operate the fire extinguishing device before the automatic fire extinguishing operation by the detector, remove the safety clip fitted to the push button on the outside of the slide needle assembly Afterwards, the pushbutton is pushed down to manually reverse the electromagnet core in contact with the tip during the operation to have the same action as in the automatic operation.

However, such a conventional fire extinguishing device is a type applicable to a sealant type fire extinguisher valve in which the sealing of the valve is triggered by the advancement of the needle pin provided at the tip of the operating rod, so that the gas is discharged. The spindle type fire extinguisher valve shown in the above has not been applied to the above method yet.

Accordingly, the present invention has been made to solve the above problems, an object of the present invention is to provide a structure for operating the valve by mechanically converting the operation of the solenoid and the solenoid electrically operated in the spindle type fire extinguisher valve.
