DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the utility model more clear, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings; it should be noted that these descriptions are only exemplary and are not intended to limit the scope of the utility model.

[0023] Embodiment 1:

[0024] like Figure 1-4 As shown, a regulating valve fault detection and alarm device is characterized by comprising: a detection module 100 and an inspection module 200;

[0025] The detection module 100 includes a valve body 110, a switch 120 threadedly connected to the valve body 110, a table 140 fixedly connected to one side of the valve body 110 via an L-shaped rod 130, and a pressure gauge 150 installed on the top of the table 140, wherein the measuring end of the pressure gauge 150 is located inside the valve body 110;

[0026] The inspection module 200 includes a turntable 210 embedded in the table 140, a limit frame movably connected to the bottom of the turntable 210, a ball 250 installed on the outside of the turntable 210, a touch switch 260 that cooperates with the ball 250 and is fixedly connected to the bottom of the table 140, and an alarm 270 electrically connected to the touch switch 260, and the alarm 270 is set on the top of the table 140; the limit frame accommodates the switch 120 inside.

[0027] Furthermore, the limit frame includes a rotating shaft 220 rotatably connected to the bottom of the turntable 210, two vertical plates 230 fixedly sleeved on the outside of the rotating shaft 220, and a limit plate 240 fixedly connected to one side of the vertical plate 230. The two limit plates 240 are respectively located on both sides of the switch 120. With this structural design, once the switch 120 becomes loose, the limit plate 240 will be moved, and then the turntable 210 will be guided to squeeze the touch switch 260 with the ball 250. It should be noted that since the limit frame rotates around the rotating shaft 220, it will not affect the manual opening or closing of the switch 120.

[0028] Furthermore, the longitudinal section of the turntable 210 is set to be T-shaped and made of plastic. The turntable 210 is set to be T-shaped, and a stepped hole compatible with the T-shaped structure of the turntable 210 is provided on the table. This shape design can prevent the turntable 210 from falling; in addition, the turntable 210 is made of plastic material to reduce its weight and reduce the resistance during rotation.

[0029] Furthermore, the touch switch 260 is located outside the turntable 210. When the touch switch 260 is in contact with the ball 250, the touch switch 260 is in an on state. With this structural design, once the switch 120 becomes loose, the limit plate 240 is moved, and then the turntable 210 is guided to squeeze the touch switch 260 with the ball 250, and then the alarm 270 is turned on and an alarm sound is emitted.

[0030] Embodiment 2:

[0031] Combination Figure 1-3 As shown, based on the first embodiment, a schematic label 300 is adhered to the top of the switch 120, and the top of the schematic label 300 is provided with the word "open" and a rotation direction arrow. This means can prevent the user from reversing the switch 120 and reduce the probability of the switch 120 being sprained or broken.

[0032] Embodiment three:

[0033] Combination Figure 1 , 3 and Figure 4 As shown, on the basis of the above two embodiments, a connecting rod 400 is connected between the two limiting plates 240 , and the connecting rod 400 is located above the switch 120 . The connecting rod 400 is provided to ensure the firmness of the connection between the two limiting plates 240 .

[0034] The working principle and use process of the utility model are briefly described as follows: in the initial state, the pressure gauge 150 monitors the interior of the valve body 110 in real time to reduce the probability of damage to the valve body 110 due to excessive pressure. Then, when the interior of the valve body 110 needs to be opened, the user rotates the vertical plate 230 and the limit plate 240 through the rotating shaft 220 to stop the limit plate 240 from restraining the switch 120. Then, when closing the interior of the valve body 110, manually close the switch 120 and then make the two limit plates 240 stick to both sides of the switch 120. If the switch 120 is loose, the switch 120 will reverse by itself, and the reversal force is transmitted to the two limit plates 240. Then, the turntable 210 rotates with the ball 250, and the ball 250 squeezes the touch switch 260, causing the alarm 270 to alarm, and then informs the user to repair it in time.

[0035] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
