A guide device is also provided between the pressure plate 7 and the mounting base 8, and an adjustment device is also provided between the pressure plate 7 and the mounting base 8.

[0022] To improve the stability of the pressure plate 7 during sliding, the guiding adjustment device includes: a plurality of guide holes 12 opened on the pressure plate 7, and guide posts 13 on the mounting base 8 that match the guide holes 12.

[0023] To facilitate adjustment of the pressure plate 7 according to the required water pressure, the adjustment device includes: an adjustment thread (not shown in the figure) on the sliding rod 9, an adjustment nut 14 locked on the sliding rod 9, and a spring 15 sleeved on the sliding rod 9, one end resisting the adjustment nut 14 and the other end resisting the pressure plate 7.

[0024] In order to facilitate cooperation with the pressure plate 7 to detect water pressure, the sensing device includes: a weighing sensor 16 installed in the nut body 2, a connecting rope 17 installed on the weighing sensor 16, a weighing iron block 18 installed on the connecting rope 17, and a strong magnetic block 19 installed on the pressure plate 7.

[0025] In order to issue a warning when the water pressure is insufficient, the warning device includes a warning light module 20 installed on the hydrant body 2, and the warning light module 20 is electrically connected to the weighing sensor 16.

[0026] In order to rotate the rotating rod 3 smoothly, the rotating device comprises a support seat 21 arranged on the bolt body 2, and a bearing 22 arranged in the support seat 21, and the rotating rod 3 is fixedly connected with the inner ring of the bearing 22.

[0027] In order to facilitate the control of the opening and closing of the valve body 1, the lifting device comprises a connecting block 27 arranged on the upper end of the valve rod 5, a threaded hole 23 arranged on the connecting block 27, and a connecting thread (not shown in the figure) arranged on the rotating rod 3 and matched with the threaded hole 23, and the valve rod 5 is further provided with a rotation stopping device between the valve rod 5 and the bolt body 2.

[0030] Working principle: during installation, the adjusting nut 14 is adjusted according to the actual water pressure required, the spring 15 with appropriate elasticity is replaced, and the sensing value between the load cell 16 and the warning device is adjusted;

[0031] During use, the fluid impacts the pressure plate 7, and the pressure plate 7 is pushed to move towards the valve plate 6, at this time, the magnetic force on the load cell 18 is enhanced due to the close proximity of the strong magnetic block 19, so that the value obtained by the load cell 16 is increased, and a signal is transmitted to the warning device to stop emitting light, when the water pressure is insufficient, the pressure plate 7 moves away from the valve plate 6 under the action of its own gravity and the spring 15, at this time, the magnetic force on the load cell 18 is weakened, so that the value obtained by the load cell 16 is smaller, and a signal is transmitted to the warning device to emit light, thereby playing a warning role.

[0032] When water is used, the rotating rod 3 is twisted, at this time, the valve rod 5 is driven to gradually move upwards with the valve plate 6 under the action of the connecting thread, the threaded hole 23, the clamping screw 25 and the rotation stopping groove 24, thereby releasing the sealing of the valve seat 4 and enabling the fluid to flow out.

[0033] The basic principle and main features of the utility model and its advantages are shown and described above, and those skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments, the above-mentioned embodiments and descriptions are only used to illustrate the principle of the utility model, and various changes and improvements can be made to the utility model without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed, and the protection scope of the utility model is defined by the appended claims and their equivalents.
