DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: Figure 1 and Figure 2 The liquid-sealed leakage detection manual continuous sewage valve shown includes a liquid-sealed sewage valve body 1, on the surface of which a first connecting pipe 101 and a second connecting pipe 102 are installed. The first connecting pipe 101 and the second connecting pipe 102 are provided with flanges, which can be used to connect to various medium pipelines.

[0025] Among them, combined with Figure 3 As shown, a valve seat 2 is fixed to the upper end surface of the liquid-sealed sewage valve body 1, and a vertical valve stem 3 is rotatably installed inside the valve seat 2. The top of the valve stem 3 passes through the top of the valve seat 2 and is fixed with a hand wheel 301 to facilitate the control of the valve stem 3 by the hand wheel 301.

[0026] At the same time, the middle part of the valve seat 2 is hollowed out and the middle part of the valve stem 3 is exposed. Two fixing frames 4 are symmetrically fixed on both sides of the hollow middle part of the valve seat 2. A power supply 5 and a buzzer 6 are respectively fixed on the side of the two fixing frames 4 away from each other. Elastic electric connecting rods 7 are fixed on the inner sides of the two fixing frames 4. The two elastic electric connecting rods 7 are electrically connected to the power supply 5 and the buzzer 6 respectively, and the elastic electric connecting rods 7 elastically abut the middle part of the valve stem 3. Copper rings 8 for conduction are sleeved at the upper and lower positions of the middle part of the valve stem 3, and the valve stem 3 itself is insulated. Therefore, when the liquid-sealed sewage valve body 1 leaks, the position of the valve stem 3 will change, so that the elastic electric connecting rod 7 will elastically abut against the copper ring 8 on the valve stem 3, so that the copper ring 8 can electrically connect the power supply 5 and the buzzer 6, so that the buzzer 6 can automatically sound an alarm, thereby reminding the staff in time.

[0027] Specific as Figure 4 As shown, the elastic electric connecting rod 7 includes a fixed cylinder 701, and the fixed cylinder 701 is horizontally fixed to the middle part of the inner side of the fixed frame 4. The fixed cylinder 701 is plugged with a horizontal movable cylinder 702 at one end facing the valve stem 3, and the movable cylinder 702 is fixed with a metal head 703 for abutting the surface of the valve stem 3 or the copper ring 8 at one end away from the fixed cylinder 701, and the metal head 703 is connected to a wire 704, and the wire 704 passes through the interior of the fixed cylinder 701 and the movable cylinder 702, and is connected to the power supply 5 or the buzzer 6, so that when the metal head 703 abuts the surface of the valve stem 3, the valve stem 3 can cut off the power supply of the power supply 5 to the buzzer 6, and when the metal head 703 abuts the surface of the copper ring 8, the power supply 5 can supply power to the buzzer 6 through the copper ring 8.

[0028] In addition, a spring 705 is fixed inside the fixed cylinder 701, and the spring 705 pushes the movable cylinder 702 horizontally outward from the end of the fixed cylinder 701, so that the metal head 703 can stably contact the surface of the valve stem 3 or the copper ring 8 under the elastic action of the spring 705 to avoid poor contact.

[0029] In this embodiment, the power source 5 includes a battery box and batteries arranged inside, and a sealing plate 501 is installed on the side of the power source 5 away from the fixing frame 4 to facilitate staff to replace the batteries in the power source 5 by opening the sealing plate 501 .

[0030] Working principle of the utility model: when the liquid-sealed leakage detection manual continuous drain valve is in use, when the liquid medium in the liquid-sealed drain valve body 1 leaks out from the valve cavity, the position of the valve stem 3 will usually change accordingly. At this time, the movable cylinder 702 elastically installed in the fixed cylinder 701, the metal head 703 at its end will abut against the copper ring 8 on the valve stem 3 after the position change, so that the power supply 5 and the buzzer 6 are connected to form a power supply circuit, that is, the power supply 5 can supply power to the buzzer 6 through the elastic electrical connecting rod 7 and the copper ring 8, so that the buzzer 6 sends out an alarm, thereby timely reminding the staff. Compared with the prior art that requires the staff to observe and judge by themselves, the device can reduce safety hazards and property losses, and has a better use effect.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
