Description

Technical Field

[0001] The utility model belongs to the technical field of valves, and in particular relates to a valve with leakage alarm. Background Art

[0002] Valves are relatively common in life. They are divided into gas valves and liquid valves. Among them, liquid valves are more commonly used. Liquid valves are usually devices used to control liquid flow and pressure. When liquid valves are installed and connected to water pipes, they need to be sealed to prevent leakage during use.

[0003] However, it is often impossible to detect water leaks in newly installed water pipes in time. Water leaks may occur after a period of use, and they need to be monitored to avoid economic losses caused by failure to detect water leaks in time. However, some existing valve leakage alarm devices need to be plugged in for use. Some valves are installed in remote places or corners and cannot be powered. In addition, the connections between some valves and water pipes are of different thicknesses. The alarm cannot monitor connections of different thicknesses well, and is not convenient to use.

[0004] Therefore, a novel valve with leakage alarm is designed to change the above technical defects. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a valve with a leakage alarm. This technical solution can solve the technical problems that, under the prior art, leakage monitoring of water valve connections cannot be performed in places without power supply, and the alarm device cannot monitor water pipe connections of different thicknesses well.

[0006] In order to solve the above technical problems, the utility model provides a valve with leakage alarm, including a valve body, wherein the left and right sides of the valve body are respectively fixedly connected with connecting pipes, upper arc shells are respectively arranged on the two connecting pipe side walls near the top, and lower arc shells are respectively arranged on the two connecting pipe side walls near the bottom, and hinge plates are respectively fixedly connected with the outer walls of the upper arc shell and the lower arc shell near the rear side, and the two hinge plates are movably connected, and arc openings are respectively opened on the left and right sides of the upper arc shell and the lower arc shell, and the upper arc shell and the lower arc shell are respectively sleeved on the side walls of the connecting pipe, a locking mechanism is respectively arranged between the outer walls of the upper arc shell and the lower arc shell near the front side, and an alarm device is respectively arranged on the side of the lower arc shell away from the valve body.

[0008] The alarm device includes a buzzer, which is installed on the side wall of the lower arc-shaped shell. The bottom of the inner cavity of the lower arc-shaped shell is provided with evenly distributed drainage holes. The bottom of the lower arc-shaped shell is fixedly connected to a water receiving box. The top of the lower arc-shaped shell is not closed. Wires are symmetrically installed on the buzzer. The bottom ends of two adjacent wires respectively penetrate the water receiving box and extend into the box cover. Cotton thread is installed between the bottom ends of the two adjacent wires.

DETAILED DESCRIPTION

[0019] This specific implementation is a valve with a leakage alarm, and its structural diagram is as follows Figure 1-Figure 5 As shown, it includes a valve body 1, and connecting pipes 2 are fixedly connected to the left and right sides of the valve body 1 respectively, upper arc shells 3 are respectively arranged on the side walls of the two connecting pipes 2 near the top, and lower arc shells 4 are respectively arranged on the side walls of the two connecting pipes 2 near the bottom, and hinge plates 5 are respectively fixedly connected to the outer walls of the upper arc shell 3 and the lower arc shell 4 near the rear side, and the two hinge plates 5 are movably connected. Arc openings 12 are respectively opened on the left and right sides of the upper arc shell 3 and the lower arc shell 4, and the upper arc shell 3 and the lower arc shell 4 are respectively sleeved on the side walls of the connecting pipe 2, and a locking mechanism is arranged between the outer walls of the upper arc shell 3 and the lower arc shell 4 near the front side, and an alarm device is respectively arranged on the side of the lower arc shell 4 away from the valve body 1.

[0020] Among them, the locking mechanism includes a limiting strip 6, which is fixedly connected to the outer wall of the upper arc-shaped shell 3 near the front side, and a U-shaped plate 7 is fixedly connected to the outer wall of the lower arc-shaped shell 4 near the front side. The bottom of the limiting strip 6 passes through the U-shaped plate 7 and extends to the bottom of the U-shaped plate 7. A screw hole 8 is opened on the front wall of the U-shaped plate 7, and a bolt 9 is installed in the screw hole 8. One end of the bolt 9 extends into the U-shaped plate 7 and contacts with the limiting strip 6. The limiting strip 6 is made of plastic and can be bent to a certain extent when used. In this way, when used on a thicker water pipe, the limiting strip 6 can still be inserted into the U-shaped plate 7.

[0021] In addition, the alarm device includes a buzzer 14, which is installed on the side wall of the lower arc-shaped shell 4. The bottom of the inner cavity of the lower arc-shaped shell 4 is provided with evenly distributed drainage holes 10. The bottom of the lower arc-shaped shell 4 is fixedly connected to a water receiving box 16. The top of the lower arc-shaped shell 4 is not closed. A box cover 17 is provided on the top of the water receiving box 16. The box cover 17 matches the water receiving box 16. The water receiving box 16 is inclined. Wires 15 are symmetrically installed on the buzzer 14. The bottom ends of two adjacent wires 15 respectively penetrate the water receiving box 16 and extend into the box cover 17. A cotton thread 11 is installed between the bottom ends of the two adjacent wires 15.

[0022] Among them, the buzzer 14 is integrated and has the following functions and characteristics:

[0023] Easy to use: The integrated buzzer 14 usually has a simple interface and control method, which is convenient for users to quickly get started;

[0024] Small size: The integrated buzzer 14 is usually compact in design and small in size, suitable for embedding in various devices;

[0025] Low power consumption: The integrated buzzer 14 is usually designed to be low power, and the battery or electronics integrated inside it can minimize energy consumption while ensuring the sound effect;

[0026] High reliability: The integrated buzzer 14 has been professionally designed and tested and generally has high reliability and stability.

[0027] The buzzer 14 is a relatively mature device in the prior art and will not be described in detail here.

[0028] The inclined water receiving box 16 can enable leaked water drops to quickly slide to the bottom of the water receiving box 16 when dripping water falls.

[0029] Among them, the inner wall of the arc-shaped opening 12 is fixedly connected with evenly distributed soft plastic sheets 13, which are in contact with the connecting pipe 2. Multiple soft plastic sheets 13 are made of rubber material and can be bent arbitrarily, so that the water pipe connection can be better wrapped and debris can be prevented from entering the upper arc-shaped shell 3 and the lower arc-shaped shell 4.

[0030] When the present technical scheme is in use, first install the valve body 1 where it is needed, and connect it to the external water pipe through the connecting pipe 2, then loosen the bolt 9 to open the upper arc shell 3 and the lower arc shell 4, and then cover the upper arc shell 3 and the lower arc shell 4 over the connection between the connecting pipe 2 and the external water pipe. When closing the upper arc shell 3, the limiting strip 6 on the upper arc shell 3 will enter the U-shaped plate 7, and then press the upper arc shell 3 to make the soft plastic film 13 contact the connection between the connecting pipe 2 and the external water pipe, wrap the connection and then tighten the bolt 9 so that the bolt 9 squeezes the limiting strip 6 to lock the upper arc shell 3 and the lower arc shell 4, so that the upper arc shell 3 and the lower arc shell 4 can wrap the connection between the connecting pipes 2 of different thicknesses, effectively improving the scope of its use. If the valve body 1 at the connection between the connecting pipe 2 and the external water pipe leaks during use, the leaked water will enter the water receiving box 16 through the drain hole 10 and soak the cotton thread 11. The soaked cotton thread will connect the two wires 15, so that the buzzer 14 is powered by the battery and emits a buzzing sound, thereby achieving the alarm effect. After the alarm is detected, the bolts 9 can be loosened to disassemble the upper arc shell 3 and the lower arc shell 4. After repairing the connecting pipe 2 and the external water pipe, the upper arc shell 3 and the lower arc shell 4 can be fixed at the connection again to continue monitoring them. The box cover 17 can be removed, so that the water receiving box 16 can be opened to replace the cotton thread 11, and the buzzer 14 can be recycled, which can effectively improve its use efficiency. The buzzer 14 is common knowledge and will not be described in detail here.
