The paddle blade 丨 〇 9 rotates at a specific angle on the secondary side under the flowing water pressure ′, and the paddle-type flowing water detection unit 108 sends out a flowing water signal. III. [Summary of the Invention] However, the conventional paddle-type flow detection device is mainly due to the problem that the size of the device in the direction of the tube axis is difficult to reduce. Firstly, because the blade 109 is arranged on the secondary side of the check valve 107, the check valve 107 and the blade-type flow detection unit 108 cannot be arranged close to each other. Due to the turbulent flow near the secondary side of the check valve 107, in order to ensure the stable operation of the flow detection unit 108, the purple leaf 109 must be placed at a rectification place far from the check valve 107. The general requirement is that the position from the check valve 107 to the position of the blade 109 should be about 4 to 10 times the pipe diameter. And, because the components are not arranged in-line, it is not easy to shorten the overall length in the direction of the tube axis. Therefore, the present invention has been completed in view of the above-mentioned problem, and its subject is to provide a purple-leaf-type flow detection device whose dimensions in the direction of the tube axis are easier to reduce than in the past. * The present invention has been completed in order to solve the above-mentioned problems. The leaf-type flow measuring device related to the present invention includes the flow of water from the primary side to the secondary side.

Conduit section of length The flow rate measuring paddle constructed as above. The blade is placed on the secondary side / below for operation. Because the size in the axial direction can be greatly reduced. The μ water detection device is outside the pipe. The following description explains the openings 20 on the primary side and the secondary side ρ ^ ′ on the secondary side. "The water flow detection device has a plate-shaped structure, so it is as described above :: The so-called round two pipes 3 and 4 without flanges are arranged in a safe way 'and two: secondary side, secondary side two On the secondary side, the two pipe ends 3 and 4 are connected to a specific door on the primary side 3a and 4a with a plurality of bolts 28 = 3a 2 4a, and the two flange portions are inserted into the two with gaskets 29.

The bolts 28 of the inner nut 31 pass through the two flanges, and the inner nut 31 of the pair The distance between the two flange portions 3a and 4a and the mutual connection of the two flange portions 3a and 4m are used to detect and install the dream. After that, the inner nut 31 30 is clamped to the two flange portions 3a and 4a with * starter two, and finally the outer nut is screwed on. Adjust # = = 1 疋. In this way, by tightening and loosening the inner nut 31 to expand and reduce the distance between the crotch portions 3a and 4a, the device is adopted between the two flange portions 3a and 4a, and it is easy to report the device in and out. In addition, the device can be fixed more securely with the outer nut 30 after the device is inserted. In FIG. 1, the bolt positions are drawn more outward than actually. Next, a flow detection device according to a second embodiment of the present invention will be described. However, the same symbols are attached to the same structures, and detailed descriptions thereof are omitted. The flow detection device according to the second embodiment shown in FIG. 2 is a butterfly check valve 40 instead of the rotary check valve 2 of the first embodiment. The butterfly check valve 40 includes a pair of left and right slightly semi-circular valve bodies 41 and 42 as shown in FIG. 3. The left and right valve bodies 41 and 42 of the disc are arranged on the center line of the butterfly check valve 40. The structure rotates around the common support shaft 43. The valve bodies 41 and 42 are excited on the closing side by an excitation mechanism spring 45, and when they receive the flowing water pressure from the primary side to the secondary side, they move away from the valve seat 26 and rotate toward the secondary side against the excitation force. Generally, such a butterfly check valve 40 has the same excitation force to the left and right valve bodies 41 and 4 2. Therefore, when subjected to flowing water pressure, the left and right valve bodies 4 1 and 4 2 rotate approximately equally toward the open side.

Description of the invention (7) In contrast, the butterfly check valve 4 0 of this embodiment is configured such that one valve body 41 is easier to turn to the open side than the other valve body 42. Such a structure ^ One is a structure that can be opened by a lower water pressure than the other. For example, there are structures in which the weights of the left valve bodies 41 and 42 are different, and the excitation force of the spring 45 and the like are different. Structure. That is, a lighter valve body and a valve body with a lower excitation force can be opened by _ small flowing water pressure. Λ Therefore, as in the first embodiment, the paddle 丨 〇 in this embodiment is also disposed on the primary side of the butterfly check valve 40. However, in this embodiment, the paddle ^ 〇 is eccentrically arranged in the easier to open The primary side of the valve body 41. More specifically, as shown in FIG. 3 ', the purple leaf 10 is arranged along a slightly orthogonal direction of the rotation support shafts of the valve bodies 41 and 42, and is arranged on the center line of the butterfly check valve 40. Therefore, the rotation support shaft 10b of the purple leaf 10 is disposed at the other which is opened with a large flowing water pressure. The outer side of the valve body 42 and the wrist portion 10c thinner than the flowing water pressure receiving portion 10a cross the other. The valve body 42 is provided at the end of the wrist portion 10c with a fan-shaped flowing water pressure receiving portion 10a centered on the end. That is, the flowing water pressure receiving portion 10a overlaps one of the valve bodies 41 almost in the tube axis direction. The center angle of the flowing water pressure part 10a is about 90 degrees. Also, as shown in FIG. 2, the thickness in the tube axis direction is thinner than the flowing water pressure part ... The wrist part 10c is actually smaller than the flowing water pressure part 1 〇 a thick. In this embodiment, because the paddles are disposed on the primary side of the butterfly check valve 40, the rule in the direction of the tube axis can be reduced. In addition, the butterfly valve check valve 40 is used for the check valve system, which is particularly small at large diameters, and it is eccentrically arranged for the purple leaf 10 series, that is, the purple leaf flow pressure part 10a is arranged at a low flow pressure The primary side of the opened valve body 41 can make the blade 10 (flowing water X pressure part 10a) smaller than the piping area, so that

Description of the invention (8) Reduce the pressure drop due to the configuration of the blade 10. Since the pressure drop is mainly caused by the area of the flowing water pressure receiving portion 10a, reducing the area of the flowing water pressure receiving portion 1 can reduce the pressure drop. Therefore, although the flowing water pressure receiving portion 10a is reduced, the flowing water pressure receiving portion 10a is eccentrically arranged on the primary side of one valve body 4 which is easy to open, so the valve body 41 can reliably detect the flowing water. . When the pressure of the flowing water is above a certain value, the left and right valve bodies 4 1 and 42 are opened at the same time. At this time, because the pressure of the flowing water is high, of course, even a small flowing water pressure part 丨 0a can actually detect the flowing water. β In addition, since the rotating support shaft 10b of the blade 10 is not arranged on the valve body 41 side opened at a low flowing water pressure, it is constituted as shown in FIG. 2 and FIG. 3 on the other body 42 side. By lengthening the 10c running water detection sensitivity of the wrist, it can be turned to ° and cross, and effective to withstand the flow of the fan # measuring flow into a screw ~. ’Fructus Corni is located under the pressure of flowing water, which is more compressed than water. In this embodiment, the rotation support shaft 43 configured as the valve bodies 41 and 42 is slightly positive, and the center line of the butterfly check valve 40 is used. Therefore, the blade 10 can rotate more forcefully. Although the part 10a can adopt various shapes, the pressure drop is extremely reduced in this embodiment, such as a square, etc. At the same time, the device that can be efficiently formed is also the same as the circular plate or flange mounting method of the first embodiment. However, it is also possible to replace the circular plate shape with the first and the second tube, but it is explained that in one application mode, the control valve is generally arranged once and the flow detection device including the system or the control valve. Flow detection device related to the third embodiment of the present invention
