Description

FIELD OF THE INVENTION The present invention relates to an alarm valve for a fire alarm valve,

The present invention relates to an apparatus for detecting the flow of a fluid, and more particularly,

Conventional sprinkler installations are installed for fire extinguishing. The sprinkler system is installed in a water pipe and is installed in a water pipe. It is locked in everyday life and it detects the abnormal temperature in case of fire, so that the fuse is cut and water is sprinkled.

On the other hand, a check valve device is provided on the side of the water pipe of the sprinkler, and a device for detecting an alarm when the flow of water occurs due to a fire is provided. The present invention relates to a flow detection device for detecting flow in a fire.

Korean Patent Application No. 10-2009-0041145

In the related art water flow detection device, one end of a check valve is fixed by a rod pin, and the check valve is opened and closed while rotating. However, since the check valve rotates, there is a fear that noise may be generated at a position where the farthest from the load pin and the housing come into contact with each other when closing the valve.

In addition, since the check valves are in contact with each other, the movement angle of the ash varies according to the length of the ash, so the accuracy is low and the position of the rotation axis of the ash and the check valve Which may cause damage to syngeneic rock.

In addition, in the conventional water flow detection device, the switch is contacted through the cam portion. However, when the cam portion is installed and pivoted, a considerable space is required.

Accordingly, the present invention aims to improve noise and damage during operation of the check valve, and to reduce the size of the switch portion.

The present invention realizes opening and closing of a check valve in a water pipe by using a clapper. Unlike the structure in which only one side of the check valve is opened and closed, the entire clapper performs a linear movement, and the clapper lifts up the rotary carcass according to the movement of the running water.

In addition, a synchronous stopper was installed and the clapper of the sawtooth and the check valve was placed in a non-contact manner at a predetermined interval. Thus, we achieve the task of protecting the ash cone from stress and damage within the cone of the cone, which can occur in everyday life when contacted.

The present invention utilizes a method of directly contacting a sensor of a switch with a rotary arm, and achieves the solution of the problem of contacting the two by vertically connecting them.

In the present invention, unlike the prior art, a check valve is constituted by using a clapper, a rotary rock stopper is provided, and a rotary rock and a clapper are constructed in a noncontact manner to prevent stress and damage of a material, improve precision, .

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water flow detection device for an alarm valve for fire fighting.

The present invention is mounted between water pipes separated from a water pipe and directed to a sprinkler.

The present invention has a groove type (3) and a flange type (5) according to the connection method with the water pipe. The groove type (3) is a method in which grooves are formed at the ends of both pipes and are pinched by a housing (cover). The flange type (5) is a method of attaching both ends of a pipe and punching with a bolt / nut combination.

1 is an entire perspective view of a water flow detection device of a fire alarm valve.

An opening is formed in a side surface of the check valve housing 10 in the flow direction direction. A panel 20 is attached to the opening and a switch unit 110 is coupled to the panel.

In the case of Fig. 1, both ends of the water tube are coupled with the flange type 5, and the coupling between the shut-off valve 7 and the check valve housing is coupled to the groove type 3 at the middle portion. In the case of Fig. 1, one embodiment is shown, and both can be implemented as needed. That is, unlike FIG. 1, both ends can be connected by a groove type.

A shut-off valve 7 in the form of a globe valve is connected to the lower end of the check valve housing of FIG. The globe valve can be replaced with other types of valves as needed.

The shut-off valve 7 is open in most cases. If the shut-off valve is closed, the sprinkler does not operate due to the absence of running water in the event of a fire. As a result, the fire alarm does not work.

The shut-off valve may be actuated when it is necessary to replace the water flow detection device or to block the flow of water for inspection / replacement of other parts.

The check valve housing inner portion 10 is composed of a check valve, a rotary arm 50, a rubber packing 70 and an O-ring 90.

The check valve is located in the axial direction of the flow of the pipe. The check valve prevents the flow of water in the event of fire. Check valves are swing type and lift type. The embodiment shown in the drawings is characterized by being of a lift type. However, it can be configured as other types of valves as needed.

The check valve shown in Figs. 3a and 3b is implemented by a clapper 30 in a lift-type manner. The clapper prevents leaks due to its own weight during non-fires. In the event of a fire, runoff flows and the clapper rises as the fluid flows. The ascending clapper moves the cone rock (50).

The components of the clapper 30 are as shown in FIG. 3B. The clapper (30) is coupled to the clapper post (32) by screw connection, and the leakproof rubber ring (34) is attached to the coupling part. A nut 38 is coupled to the lower end of the clapper post 32 to limit the clapper's ascending range. The clapper pillar 32 is supported by a support base 36 and moves up and down without shaking.

The clapper pillar can be fixed to the support by forming a thread and can be supported by the check valve housing without a thread.

4A and 4B are side views showing the operation of the rotary rock. The rotary rocking arm 50 is fixed to the panel 20 with a fixing pin, one side of which is adjacent to the clapper 30 and the other side of which is connected to the switch portion. The embodiment shown in the drawings is characterized in that the fixing pin fixes the rotary arm in the horizontal direction inside the opening, and the rotary arm rotates up and down about the fixing pin. However, without the use of fixing pins, it is possible to fix the rotary rock by the friction of the rubber packing, so that the rotary rock can rotate up and down.

And is located on one side of the rotary rocking arm 50 adjacent to the clapper 30. The asbestos side and the clapper are located in a noncontact manner. If the synchrotron and clapper are kept in contact with each other, the switch may operate depending on the disturbance, and continuous stress may be applied to shorten the lifetime. When the clapper rises in response to runoff in the event of a fire, the clapper makes contact with the ash cone and consequently the ash cone turns upward.

And the other side of the rotary rock is connected to the switch 130 of the switch portion.

The rubber packing is as shown in Fig. The rubber packing 70 is located between the opening and the panel and has a structure in which the rotating piece penetrates the center of the rubber packing. The rubber packing prevents the flow of water from the check valve housing 10 through the opening to the switch portion 110. The rubber packing protects the asbestos from contact with the wall of the water pipe due to the rotation of the ash.

In another embodiment, the rubber packing is located inside the opening. The rubber packing is in close contact with the inside of the opening, and the rotating piece penetrates from the inside of the rubber packing. Therefore, no play occurs at all in the event of a fire or a fire.

An O-ring 90 is positioned between the clapper and the water tube as shown in FIG. 5 is a view showing two rubber rings mounted on an O ring and an O ring. The O-rings may be made of metal, of synthetic resin, or of rubber. The lower part of the outer surface of the O-ring is formed with a thread and is fixedly engageable with the lower part of the check valve housing.

The top of the O-ring in contact with the clapper is fitted with an upper rubber ring 92, which prevents leakage and alleviates the impact. A lower rubber ring (94) is mounted on the threaded portion of the O-ring fixedly coupled to the lower tube of the check valve portion to prevent leakage.

The switch unit 110 includes a bracket 120, a switch 13 and a restoring spring 170. The panel 20 is mounted on the outer wall of the side opening of the check valve unit, And a bracket 120 are mounted on the bracket 120. As shown in Figure 7, the bracket may be formed in a different shape, but may be in other forms. And a restoring spring 170 is mounted to the bracket 150. A rotary stone stopper 150 can be formed on one side of the bracket.

As shown in Figs. 8A and 8B, the switch 130 is connected in such a manner as to be in contact with the other side of the rotary rocking arm 50. Fig. An upper sensor 132 and a lower sensor 134 are provided at a lower portion of the switch to allow electricity to pass therethrough. The lower sensor bends downward and is not grounded to the upper sensor unless extra force is applied.

In the case of non-fire, as shown in FIG. 8A. In case of non-fire, the lower sensor is in contact with the other side of the rotary rock, and it is lifted up by the elastic force of the restoring spring and grounded with the upper sensor, and in this case, no signal is generated.

In case of fire, as shown in Fig. 8B. In case of fire, when the other side of the rotary car is lowered, the lower sensor is not subjected to the force of the rotary rock, so it is lowered by its own elasticity and self weight, and the lower sensor and the upper sensor are not grounded. In this case, an electric signal is generated and an alarm is sounded.

In case of non-fire, the lower sensor and the rotary arm are connected up and down, thereby preventing the deflection of the switch and improving the accuracy and lifetime.

The restoring spring 170 is shown in Figures 6 and 8. The restoration spring is connected to the other side of the bracket and the rotary rock. The restoration spring raises the other side of the rock when it is not fire and keeps it at a specific position. The other side of the rotary carcass is limited in its maximum elevation angle by the rotary carcass stopper 150 formed on the bracket so that one side of the rotary carcass is adjacent to the clapper in a noncontact manner, Do not.

The restoration spring should not prevent the other side of the rotary carcass from falling down during the fire. If it causes bending of the rotary carcass, it will damage the carcass. The elasticity of the restoration spring should be lower than the rigidity of the rotary carcass.

A part of the bracket may form the rotating cancer stopper 150. [ The embodiment of the drawing is as shown in the figure and is characterized by being formed as a 'C' shape. This is to accommodate swinging in the left and right direction and to facilitate replacement of the material. However, it can be formed into a different shape, such as a square shape, if necessary.

The rotary cancer stopper 150 limits the rotation range of the rotary cancer. In case of non-fire, the other side of the rotary rock is raised due to the elastic force of the restoration spring, but it is fixed at a specific position due to the maximum rising angle by the rotary rock stopper.

The clapper 30 is elevated in height by a large amount of flow at the time of a fire so that the one side of the rotary rocking arm 50 is elevated and the rotary rocking stopper 150 ), There is a limitation on the maximum falling angle.

As a result, the rotary cancer stopper has the feature of improving the precision by restricting the rotation range.

Thus, the present invention can improve the accuracy of signals using a clapper type check valve, non-contact type rotary rocker 50, upper and lower contact switches 130, restoring springs 170, and rotary rocker stoppers 150, It has an effect of increasing the life of the material.
