Detection device. According to the invention of claim 8, the sun is a, the +, the sputum, and the sputum is in the water detecting device, and the opening portion of the closed valve box is placed on the side of the flowing water detecting device. In the case of the pole = face, the aforementioned request for the flow detection device. A drain chamber is provided on the near side. According to the invention of claim 9, in the flow detecting device, when the surface of the cover provided with the opening of the closed valve box is placed on the front surface of the Ά Mk k ^ The running water detection is shocked. According to the present invention, one end is placed in contact with the peripheral edge of the valve body to form a protrusion 5 201039883. The rod of P forms a space between the rod and the periphery of the valve body to prevent the rod from being sandwiched between the wide body and the valve seat when the wide body is closed. And the inside of the valve box of the rod is pressed and pressed to the opening direction of the valve body, and the rod can follow the rotation when the valve body is only slightly opened. [Embodiment] In the flowing water detecting device of the present invention, an elastic body or a hammer 'magnet or the like can be used as a pressing means for biasing the rod end inside the valve casing toward the valve body opening direction. Further, the position of the biasing means may be provided inside the valve casing but is preferably provided on the side of the rod which is protruded to the outside of the valve casing. The flowing water detecting device is configured to discharge the water when the sprinkler head provided on the secondary side is actuated to reduce the pressure on the secondary side, and the valve body is opened when the primary side pressure and the secondary side pressure of the flowing water detecting device generate a differential pressure, and the valve body is detected. Open and output signals. The nozzle diameter of the sprinkler head has a large difference from the valve port diameter of the flowing water detecting device. The swirling amount of the valve body that is opened from the primary side following the secondary side pressure reducing amount is extremely small. Therefore, it is preferable that the valve seat abutting surface of the valve body is formed to protrude toward the primary side. In addition, the protruding portion also functions as a hammer, and has a function of causing the valve body to move in the closing direction in the open state of the reading body. In order to exert the effect of the hammer, the material of the projection is preferably made of a metal material, specifically, a copper alloy or iron. The locking portion provided on the periphery of the valve body is disposed at a position eccentric from the central axis of the valve body, and the position of the rod is also disposed at a position eccentric from the central axis of the valve body, thereby making the flow detecting device simple. Specifically, the rear side of the flow detecting device eccentrically from the center axis of the wide body is 201039883, so that the rod protrudes from the side of the flowing water detecting device, and (4) the drain valve is disposed close to the configuration of one side of the flowing water detecting device: The switching means and the drain valve are possible. Further, when the surface in contact with the rod of the locking portion is provided at a position facing the reading surface, the movement of the rod end inside the valve box toward the wide body opening direction is blocked by the locking portion when the cylinder is closed. On the other hand, when the valve body in the open state is closed, the locking surface can retract the rod end that has been rotated to the secondary side and the rod end of the state of the 4th mountain is in the original position.实施 ❾ [Embodiment] Hereinafter, an embodiment of the invention will be described with reference to Figs. 1 to 4 . BRIEF DESCRIPTION OF THE DRAWINGS Fig. 2 is a plan view of a flowing water detecting device of the present invention. Figure 3 is a cross-sectional view of the X-X of the image circle. Figure 4 is a cross-sectional view of the Υ-Υ of Figure 2. Fig. 5 is a view showing the state in which the valve body of Fig. 4 is open. The flowing water detecting device of the present invention is composed of a main body and a water opening valve. I Row The main body 1 has a flange on the upper and lower sides. It is difficult to form, and a partition 3 is formed between the primary side I and the secondary sputum. In the next door communication port 4, in the communication port 4 _ + phase • 丨η 灿 soil 3 teeth "have a valve seat 5. One of the sides is provided with a cylindrical shape on the valve seat 5, and a valve body 6' is planted on the valve body 6 at the edge of the valve body 6 to form a valve body seat surface 5A with the valve seat 5; The bearing 7, the bearing 7 is inserted through the shaft 8, and the valve body 6 is configured to rotate. It is a case that the valve seat abutting surface of the valve body 6 is provided with a projection I 9 with the shaft 8 as a fulcrum, and the convex portion 9 is housed inside the valve seat 5 in a state where the valve body 6 201039883 is located at the valve seat 5. Further, a card projecting in parallel with the surface on which the valve is disposed is formed on the periphery of the valve body 6. At the locking portion H), the valve body seat surface of the lever-actuated lever "-end, the lever u-locking β H) is locked from the opposite surface i〇a. The card is eccentrically baked from the central axis of the valve body; when the cover 1 of the opening 1 of the main body 1 is a front surface, the heart: the rod of the dog is located behind the side, and the drain valve B is described later. Set in front. The other end 12 of the rod 11 is protruded at least outside the body. The 受 is supported by the shaft 11 Α shaft of the middle portion, and is configured as a rod. It can be freely rotated in the direction of the second side of the flowing water detecting device in the direction of the :1〇. The other end 12 of the rod U is located in the valve opening and detecting (four) terminal box 13 which is disposed outside the main body ,, and the terminal box 13 accommodates the limit opening signal of the output signal when the valve body 6 is opened. Mechanism i 5, terminal block 16. The other end 12 of the rod 11 is biased in the direction of the primary side of the flow detecting device by the spring 17 provided in the terminal box 13. The spring pressure of the spring 17 causes the U end of the rod inside the body 1 to be biased toward the face 1A direction of the locking portion 10. However, since the force of the spring 17 is smaller than the force for opening the valve body 6, the valve body 6 is not opened by the spring pressure of the spring 17. The end of the other end 12 of the rod 11 is in a state of abutting against the limit switch pressing portion 18 of the timer mechanism 15. The limit switch pressing portion 18 is biased toward the limit switch 14 by the biasing means (not shown) in the timer mechanism 15, and the other end 12 of the lever 11 prevents the movement of the limit switch pressing portion 18 toward the limit switch 14 side. . After the other end 12 of the lever 11 is separated from the limit switch pressing portion 18, the limit switch pressing portion 18 is moved toward the limit switch 14 side by the biasing means in the timer mechanism 丨 5 to issue a signal for actuating the limit switch 14. A drain valve B is provided in the vicinity of the terminal box 13 in the main body 1, and an opening (not shown) communicating with the drain valve B is formed on the secondary side II of the main body 1. The flow path inside the drain valve B is a curved angle valve structure, and the discharge port of the drain valve b is provided on the bottom side of the flowing water detecting device. The drain valve B and the body i are connected by a plurality of bolts: they are disposed on the body 1. Since the handle 2 1 of the drain valve B is disposed in front of the flowing water detecting device, the opening and closing operation of the drain valve B is easy. The operation of the flowing water detecting device described above is explained. The flow detection device of the present invention is provided on the water-filled fire-extinguishing equipment pipeline, and the pipeline connected to the primary side is connected to a water source (not shown) or a pressurized q water supply device, etc., and is connected to the pipeline of the secondary side II. Sprinkler head not shown. After the fire k occurred, the sprinkler head near the fire was activated and the nozzle of the sprinkler head was opened. Since the water in the pipeline is discharged from the nozzle of Lishuitou, the pressure of the water in the pipeline is reduced. The pressure reduction in the line connected to the secondary side of the m-head reduces the pressure on the secondary side π of the flowing water & Therefore, the force of pressing the valve body 6 by the pressure of the water of the secondary side π is reduced, and the valve body 6 is rotated in the opening direction by the pressure of the water of the secondary side I. The rotation of the valve body 6 separates the locking member 11 provided on the periphery of the wide body 6 from the rod 11 which is in contact with the locking portion 1 in the case of the distal closing valve. 9 201039883 The end of the rod 11 is rotated in the direction of the secondary side II. k is rotated to close the terminal box 13 and the 钿 12 is separated from the limit switch pressing portion 18 of the timer mechanism 15. Preventing the movement of the limit switch u from leaving 12 causes the limit switch pressing portion 18 to move toward the limit switch 14 side, and sends a signal (the limit switch 14 is actuated. The end lever 11 signals that the sprinkler has been actuated, so that the pair has The sprinkler head is activated to start the pump of the water supply, or to inform the building that there is a fire alarm. The following describes the action when the valve body is closed. The valve body 6 is closed after the vibration of the water in the pipeline is instantaneously closed. Since the locking portion 1 of the valve body 6 is pressed and rotated to the end of the 熊11 of the secondary side π direction and is located at the valve seat 5 and then returned to the closed state, the rod 丨丨 is also opened λ 力 force J return to the original BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a cross-sectional view of a flowing water detecting device of the present invention.
