Description of the new model: [Technical field to which the new model belongs] * This new model is a water flow detection device installed on the piping of fire protection equipment such as sprinkler equipment or bubble fire equipment. [Prior art] The conventional water flow detection device is configured as a swing-clamp check valve structure. The interior of the body is divided into a primary side chamber and a secondary side chamber by a partition wall. A communication port is formed in the partition wall, and the communication port is opened and closed by a valve body of the shaft support building. In the water flow detection device, the valve body is normally closed, and the pressure on the secondary side is reduced because the water head connected to the secondary side is opened, and the valve body rotates to generate a water flow from the primary side to the secondary side. —It is known that in order to detect the rotation of the valve body at this time to output a signal, the shaft fixed to the valve body is protruded from the outside of the body, and the rotation limit of the shaft reaches a predetermined angle or more. In the method, a long rod is installed on the shaft, the displacement of the valve body is enlarged, and a signal is output through a limit switch provided near the front end of the rod. (For example, refer to Patent Literature 丨). In addition, another conventional structure is that an arc-shaped large rise is provided on the primary side of the body to reduce the water flow area of the communication hole of the communication hole between the secondary side chamber and the secondary side chamber.] According to this structure, the flow from the primary side to the The rotation of the valve body caused by the water flow on the secondary side is very important. A large switch is detected by a limit switch located near the valve shaft and the signal is output. (For example, refer to Patent Document 2). (Patent Document 丨) Japanese Patent Publication No. 7-265454 (Page 3-4 5 M276590, Fig. 2) (Patent Document 2) Japanese Patent Publication No. 9/29995002 (Page, Figure 1) ) [New content] In recent years, in apartments, there is a tendency to arrange devices such as gas pipes, water supply and drainage equipment, and water flow detection devices for fire prevention equipment to focus on one space. Water flow detection devices that can be installed in narrow spaces The demand is increasing, and a simple and small-sized water flow detection device as described in the aforementioned Patent Documents i and 2 is required. Furthermore, it is not only small, reliability or operability, and easy maintenance. In order to detect the rotation of the valve body caused by the movement of the soil head, the water flow detection device described in Patent Document 1 uses a long rod to amplify the displacement of the rotation of the intermediary body, and outputs it with a limit switch. The letter $, but because of the long rod, limit switch or delay mechanism provided at the front end of the rod, the overall shape of the water flow detection device becomes larger. In addition, the water flow detection device described in Patent Document 2 is provided with arc-shaped protrusions on the primary side of the valve body, and it is difficult to process the arc-shaped protrusions. Unless a dedicated mold is used for the production, the formation is difficult. In addition, in order to form a mold in order to form an arc-shaped protrusion according to the size of the water flow detection device, the mold manufacturing cost is extremely expensive. From the above two types of water flow detection devices, in order to make the carcass rotation generated by the water flow easy to detect by the limit switch, the setting rod or arc-shaped protrusion is regarded as the arc-shaped protrusion of the magnifying mechanism described in 6 M276590. If it is too long, it will get stuck in large institutions in the flow path. Instead of Patent Document 2, linear protrusions and walls may be used, which may prevent the valve body from being opened. Therefore, this new type of flow detection device is used to achieve miniaturization, high reliability, and ease of maintenance. Problem, the purpose of which is to provide water that can be manufactured at low cost and has

P The water flow detection device of claim 5 of the patent scope is the water flow detection device of item 4 of the middle scope. In the carcass, a through-cylinder is inserted from the opposite end of the engagement portion of the cylinder 2 The shaft body with a small inner diameter and a small inner diameter penetrates outside. The water flow detection device of the scope of patent application No. 6 of T'k is in the water flow detection device of No. 4 of the patent scope. The inter-body rotation detection mechanism is equipped with a cam; it is driven by the rotation of the cam Lever; delay device, rain often keeps the starting mechanism by lever; and limit switch for signal to external wheel =. 1 The water flow detection device in the scope of patent application No. 7 is the water flow detection device in the scope of patent application No. 6. The peripheral edge of the cam is provided with a circular arc portion, a straight line portion, and a lock for the cam brake member to be locked. Generally, a load is applied to the closing direction of the valve body by an elastic pressing mechanism. The water flow detection device under the scope of patent application No. 8 is the water flow detection device under the scope of patent application No. 6. The rod usually applies a load in the direction of preventing the delay device from starting by a spring mechanism. The water flow detection device of the patent application scope item 9 is the water flow detection device of the patent application scope item 6, the rod system has a curved shape, and a fulcrum is set in the middle to rotate. The water flow detection device under the scope of patent application item 10 is in the water flow detection device under the scope of patent application item 4. The valve body rotation detection mechanism is provided with 8 M276590 · On the side of the body, an opening plugged by a cover is provided. In front of the body. The water flow detection device for the w member of the scope of the patent application is in the water flow detection device of the 10th range. A terminal block is provided in front of the valve body rotation detection mechanism of J, J ^ T company 4. The water flow detection device in the scope of application for the patent No. 12 is the water flow detection device in the scope of application for the patents No. 1G or U. The constituent elements on the side of the body are # 由 能; Cover covered. θ According to the new item in the scope of the patent application, as a mechanism for amplifying the displacement of the valve body, by providing protrusions on the body, miniaturization of the water flow detection device can be achieved, and by rotating the valve body The height position of the moving shaft is approximately equal to the position of the same degree of the cymbal seat, and the protrusion provided on the valve body can be smoothly rotated without engaging with the inner wall of the communication port. According to the new type of patent claim 2 in the patent claim, by projecting beyond the valve body: it is formed into a tapered shape with a tapered front end. As the valve body opens, the gap between the communication port = the protrusion becomes larger, so it can Prevent the debris existing in the piping from being stuck in Hall I, according to the new type of patent application No. 3, so that the protrusion can be disassembled, clamped between the valve body and the protrusion, and then dry again, not only to form a water stop The structure of the member Luo is easy to exchange because the protrusions can be removed when the water-stop member is to be exchanged. In two: two special: the new item in the scope of the fourth item, because the valve body (having a cylindrical part where the post = shaft is inserted) and the key pin (have the same as the card? Card 5) Engagement mechanism) Structure that is easy to connect and separate, the body rotation detection mechanism is disassembled to easily remove the interbody, and it can be re-set = 9 M276590 The operation during the protection is easy. According to the new type of patent application No. 5, the cylindrical part of the valve body is inserted through a shaft smaller than the inner diameter of the cylindrical part at the end opposite to the engaging part, and the opening and closing action of the valve body is supported by the shaft. The valve body can be removed only by pulling the shaft out of the cylindrical portion. '.b Because there is a gap between the inner diameter of the cylindrical part of the valve body and the outer diameter of the shaft, the valve body can move slightly in the longitudinal direction in the closed state. By this "normal (_ secondary side and secondary side pressure is the same state) the state of the valve body closed, by reading the body ^-: the difference between the pressure area of the underside and the secondary side" to make the valve body compact On the valve seat side, the sealing material provided between the valve body and the valve seat is tightly sealed to prevent water leakage from the secondary side to the primary side. ^ According to the new type in the scope of the patent application, the valve body rotation detection mechanism is a simple device equipped with a cam, a cymbal, a delay device, and a limit switch. The lever is driven by the rotation angle of the cam that is linked to the valve body, and the pole is switched by the delay ^, and the switching action is performed. In order to avoid the limit switch action when the valve body is opened instantaneously, the delay mechanism is used to open the body within a certain time. The situation makes it output a signal. The switch ^ asks for the new type of patent scope item 7. The cam forms a straight portion and a ° ^ portion. The rotation of the cam causes the lever to act as a ^ delay device from the boundary between the linear portion and the arc portion. When the cam through f applies a load to the closing direction of the valve body, and the vibration of the second body causes the valve body to open instantly, the body is immediately opened again. When the valve body is removed during maintenance, the cam's locking portion is closed. When the cam brake is locked, the hinge brocade M276590 engagement mechanism is fixed at a predetermined position when the valve body is removed. According to the new types of patent applications No. 8 and No. 9, by forming the rod into a curved shape, the installation space of the rotation detection mechanism is miniaturized, and the delay mechanism is usually prevented from starting by using a spring mechanism, only in the cam Turning it to start the delay device will start the delay device. Due to the action of the spring mechanism on the rod, the valve body is opened instantaneously and closed immediately. Although the opening cam of the valve body and the rod also rotate, the delay device is caused.

Through the tooth hole 14 from the outer side of the body 1 is inserted into the cylinder Qis of the valve body 2 within the circle of the recognition door. Insert the cylindrical part 8; In the state of =, there is a gap between the hinge pin 9B and the inner diameter of the cylinder ... The Qin chain pin 9B has a male thread Η in the middle part, and the spot marking 5 is superposed on the female thread 16 4 of the hole 14 to form a removable structure. As described above, due to the engaging structure of the longitudinal groove u of the valve body 2 and the hinge pin 9 two-eighth plane 12, and the gap between the hinge pin 9B and the cylindrical portion 8, the reading body 2 can be displaced in the longitudinal direction when closed. Due to the difference between the area of the second shell π and the second side π of the valve body 2, the sealing member 2 provided on the contact surface of the valve seat will not be biased because the intermediate body 2 is tight against the valve seat vertically. Improve water-stopping performance. When the valve body 2 is removed with a bamboo slip, only the hinge pin 9B can be removed from the body to remove the body 2. Furthermore, in the case where the carcass 2 which is temporarily removed is used again ', only the Min body 2 and the chain link pin 9A can be engaged, which can be easily connected and aligned. With this, the valve body 2 can be removed and installed again, and maintenance work can be performed without connecting the detection mechanism 3. Please be suspicious Next, the description of the valve body rotation detection mechanism > The valve body rotation detection mechanism 3 is provided with a cam 13, a lever 17, a delay mechanism 18, and a limit switch 19. , 13 M276590… cam 13 ′ is provided with a long hole in the center, and is inserted by one 20 of one end of the chain pin 9A with a slightly same cross-section shape, so that the male thread carved on the front end of the money key lock 9a is screwed with the nut 20A ， 俾 is fixedly set cam 13. The cam ^^ system = the shape of the disc forming a notch 'is formed at both ends of the arc portion 21A: straight: Shao 2 1 B 〇 A hole is formed at the lower end of the circular solitary portion 21A to connect the spring body 22a. The spring body 22A is used to press the cam 13 clockwise, and it has the function of pressing the valve body 2 against the valve seat 7A through the hinge pin 9A. Eighth ^ A cam brake 13A is provided near the cam u. The cam brake 13A prevents the hinge pin μ_ from being rotated by the weight of the cam 2 itself and the restoring force of the elastic body 22A when the valve body 2 is removed during maintenance, so that the pin is in a substantially vertical state from a plane 12 .

The lever Π is a "Lj-like" shape that bends a flat plate and presses the f-curve part of the shaft to turn it. The horizontal portion 23 is straight with the cam 13 and is pressed downward by the spring body 22B. The vertical part 24, by the action of the elastic body 22B, presses the push rod of the starter mechanism of the delay mechanism 18. The spring reaction mechanism between the 'cam 13 and the rod I' can use a spring body, but it can also be replaced. They are hammers, magnets, etc., or used in combination. The delay mechanism 18 has an internal structure of an air damper ⑽ 仏 ㈣ structure. The air damper 'its-example in the aforementioned patent reading 1 (said Japanese Patent Application Laid-open No. 14 M276590 旎) has not been revealed. The structure, so its explanation is omitted. By the rotation of the lever 17 "the lever 25 moves the vertical part 24 of the lever 17 away, and the air flows into the wind. The pusher 25 slowly moves to the limit switch 19 side, so that The limit switch 19 operates. In addition to the delay mechanism other than the above, oil dampers, clockwork, or electronic timers can also be used. Limit On_ 19 'Although the normal switch is in the OFF state, it can also be used. Change the structure of the valve body rotation detection machine # 3 and use it normally in the ON state. "~" "Although the limit switch 19 is connected to the lead wire through the terminal base 26 described later, it is easy to understand the diagram in consideration of the diagram. The wire diagram is not shown in the diagram. The above-mentioned valve body rotation detection mechanism 3. It is provided on the side of the main body 1. Before the valve body rotation detection mechanism 3, a terminal seat 26 is provided. It is preferable that the stand 26 be provided facing the front so that the wiring work to the terminal base 26 can be performed from the front face of the main body 1. The valve body rotation detection mechanism 3 and the terminal seat 26 described above are covered with protection 1 27 to prevent water or dust pollution. If the protective cover a? Is slid in the front, even if there is almost no gap on the side of the water flow detection device, the terminal block can be wired. Next, the operation of the above embodiment will be described with reference to Figs. Fig. 7 is a system diagram of a sprinkler device provided with the novel water flow detection device. Figure 7 shows the valve body rotation detection mechanism when the water flow detection device is in the operating state. As shown in FIG. 7, the novel water flow detection device is connected to the water source 15 and the water supply device P and the water supply device P on the primary side. The secondary mi is connected to the sprinkler heads H, H,... Usually the piping is filled with water, the secondary side and secondary side π force each other, and the valve body 2 of the water flow detection device is closed. When a fire occurs, the sprinkler head Η moves, and the water in the pipe connected to the secondary side Η flows out from the sprinkler head ，, and the pressure on the secondary side „decreases. If the M force on the secondary side π decreases, by — The thrust generated by the secondary side force on the body 2 causes M 2 to rotate 'from the secondary side! To the secondary side π generates a water flow. By the rotation of the valve body 2, the key lock 9A and the cam 13 are rotated, By rotating the horizontal portion 23 of the lever 17 (in contact with the straight portion of the cam 13) with the arc portion 21A, the horizontal portion 23 is pushed up to separate the vertical portion 24 from the push rod 25.柃 25 Slowly move the limit switch 19 to the limit switch 19 by the delay mechanism 18 to make the limit switch 19 move. The signals generated by the limit switch 19 i, "set P start, supply water from the water source w to the The moving sprinkler head of the Li water head H material continuously sprays water to eliminate the fire. : Man, 5 brothers, the maintenance steps of the valve body of this new type of water flow detection device. Heart… (screw-on: this miscellaneous: the second series looses the female thread 16 of the male yoke 9B after releasing water) and pulls out the hinge pin 9B. The door is: ow 'to remove the cover 1A located in front of the body 1. Since the upper part of the body 1 can be seen from the opening of the body 丨 and lifted out to the outer circle 8, Γ can hold the cylindrical part 8 toward the valve body 2 and take it out from the body 1. Skirt 10 kg: The valve body 2 is removed and the sealing member is replaced. Then assemble the valve body 2 and insert the valve body 2 through the opening of the body i: 16 M276590 inside. Connect valve body 9 & 12. At this time, the vertical slot 11 and the hinge pin 9A bis are flat, and the camber plane 12 forms a substantially vertical state due to the cam system. Therefore, the energy piece: the hinge lock 9A bis is engaged. Now it is in the vertical groove with the valve body 2 丨 丨 It is easy to insert the hinge pin 9B from the body and then insert the male thread 15 and the female thread ~ ==: 8.
