Description

Technical Field

[0001] This utility model belongs to the field of flange protection technology, and in particular relates to a flange shell cover. Background Technology

[0002] In industrial piping systems, flange connections serve as crucial interfaces for pipeline components, playing a key role in achieving pipe connection and sealing. However, flanges are constantly exposed to complex environments such as corrosion, dust, and moisture, making them highly susceptible to sealing failure or structural damage. When flanges are corroded by media, their metal surfaces are gradually damaged, leading to decreased connection strength and increased leakage risk. The intrusion of dust and moisture not only affects the flange's sealing performance but can also cause component corrosion. Currently, while some protective enclosures offer some protection, they lack real-time monitoring of leaks, making it difficult to provide timely warnings for even minor leaks in the flange, thus failing to meet the stringent requirements of industrial production for pipeline safety and stable operation.

[0003] Therefore, it is essential to invent a flange housing cover. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a flange housing cover, including an upper cover, a lower cover, side lips, hinges, bolts, a water storage pipe, a water level sensor, a mounting base, a buzzer, and a drain screw. The upper cover and the lower cover are both integrally provided with side lips on the same side, and are connected on the other side by the hinges. The bolts fix the upper cover and the lower cover together through the side lips. The water storage pipe integrally provided on the lower cover has a water level sensor installed inside, and a buzzer is installed on the mounting base integrally provided below it. A drain screw is installed at the lower end of the water storage pipe.

[0005] Preferably, the upper and lower circular covers have the same structure and can be opened and closed by the hinge. The upper and lower circular covers can enclose the flange structure connected together.

[0006] Preferably, the axis of the water storage pipe integrally provided on the lower cover is perpendicular to the ground, and a drain hole is provided through the bottom of the water storage pipe, and a drain screw head is installed at the drain hole by thread.

[0007] Preferably, a water level sensor is fixedly installed on the inner wall below the bottom of the water storage pipe, and an integral mounting base is provided on the outer wall below the pipe. The mounting base is a circular boss structure.

[0008] Preferably, the mounting base has a built-in controller, which is connected to an external power source, a water level sensor, and a buzzer. The water level sensor can control the buzzer through the controller.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The upper and lower circular covers of this utility model are connected by hinges and fixed by bolts, which can tightly wrap the flange. Combined with the side lip design, it can effectively isolate external corrosion, dust and moisture, provide comprehensive protection for the flange and extend its service life.

[0011] The water storage pipe and water level sensor installed on the lower cover of this utility model work together to monitor the leakage at the flange connection in real time. Once a leak occurs, liquid flows into the water storage pipe. When the water level reaches the set threshold, the water level sensor triggers a signal, which controls the buzzer to sound an alarm through the built-in controller. This makes it easier for staff to detect and deal with the leak in a timely manner and reduce safety hazards.

[0012] The drain screw design at the bottom of the water storage pipe of this utility model facilitates the rapid discharge of liquid in the water storage pipe after a leak is detected. It also facilitates regular cleaning and maintenance, ensuring the continuous and stable operation of the device. Attached Figure Description

[0020] As attached Figure 1 To be continued Figure 3 As shown:

[0021] This utility model provides a flange housing cover, including an upper cover 1, a lower cover 2, a side lip 3, a hinge 4, a bolt 5, a water storage pipe 6, a water level sensor 7, a mounting base 8, a buzzer 9, and a drain screw head 10. The upper cover 1 and the lower cover 2 are both integrally provided with side lips 3 on the same side, and are connected on the other side by the hinge 4. The bolt 5 fixes the upper cover 1 and the lower cover 2 together through the side lips 3. The water storage pipe 6 integrally provided on the lower cover 2 has a water level sensor 7 installed inside, and a buzzer 9 is installed on the mounting base 8 integrally provided below it. The lower end of the water storage pipe 6 is installed with a drain screw head 10.

[0022] Furthermore, both the upper circular cover 1 and the lower circular cover 2 are made of high-strength, corrosion-resistant stainless steel, and their structures are identical. One side of the upper circular cover 1 and the lower circular cover 2 is hinged by a hinge 4, which is also made of stainless steel and offers excellent corrosion resistance and rotational flexibility, allowing the upper circular cover 1 and the lower circular cover 2 to open and close around the hinge point. When it is necessary to install or remove the flange housing circular cover, the upper circular cover 1 and the lower circular cover 2 can be opened and placed over the connected flange structure. Then, bolts 5 are passed through the pre-drilled bolt holes on the side lips 3 of the upper circular cover 1 and the lower circular cover 2 to secure them together, forming a complete circular cover that tightly encloses the flange structure, effectively resisting external corrosion, dust, and moisture damage to the flange.

[0023] Furthermore, a water storage pipe 6 is integrally installed at the center of the bottom of the lower circular cover 2. The water storage pipe 6 is also made of stainless steel, and its axis is perpendicular to the ground. The water storage pipe 6 is a hollow cylindrical structure with a drain hole extending through the bottom. The inner wall of the drain hole has internal threads. The drain screw head 10 is made of stainless steel, and its outer surface has external threads that match the internal threads of the drain hole. It is installed at the drain hole via a threaded connection. When leaked liquid is collected in the water storage pipe 6, if it needs to be drained, the drain screw head 10 can be unscrewed to allow the liquid to drain out from the drain hole.

[0024] Furthermore, a water level sensor 7 is fixedly installed on the inner wall of the bottom of the water storage pipe 6 by welding. The water level sensor 7 uses a high-precision liquid level sensing element, which can sensitively detect changes in the water level inside the water storage pipe 6. On the outer wall of the bottom of the water storage pipe 6, a circular boss structure mounting base 8 is integrally set, and the mounting base 8 is also made of stainless steel. The mounting base 8 provides a stable mounting foundation for the water level sensor 7, and also provides convenient space for subsequent wiring and equipment installation.

[0025] Furthermore, the mounting base 8 has an internal cavity housing a controller (not shown). The controller uses an industrial-grade microcontroller with stable signal processing and control functions. The controller is connected to an external power supply, a water level sensor 7, and a buzzer 9 via wires. The wires are made of high-temperature resistant and corrosion-resistant insulated wires to ensure the stability and safety of signal transmission. When the water level sensor 7 detects that the water level in the storage pipe 6 has reached a preset threshold, it transmits a signal to the controller. Upon receiving the signal, the controller immediately issues a control command, driving the buzzer 9 to sound an alarm, thus promptly alerting personnel to a leak at the flange connection so that appropriate measures can be taken.

[0026] The working principle is as follows: First, during the installation process, since the upper circular cover 1 and the lower circular cover 2 are hinged by the hinge 4, they can be opened and fitted onto the outside of the flange structure. Then, the upper circular cover 1 and the lower circular cover 2 are fixed by using bolts 5 through the bolt holes on the side lip 3, so that the entire circular cover tightly wraps around the flange. The high-strength and corrosion-resistant stainless steel material, combined with the design of the side lip 3, can effectively isolate external corrosion, dust and moisture, providing protection for the flange.

[0027] Secondly, when a leak occurs at the flange connection, the leaking liquid flows along the inner wall of the dome into the water storage pipe 6 at the center of the bottom of the lower dome 2. The water storage pipe 6 is vertically arranged and has a hollow cylindrical structure, which facilitates liquid collection.

[0028] Then, as liquid continuously accumulates in the water storage pipe 6, the high-precision water level sensor 7 detects changes in water level in real time. Once the water level reaches the preset threshold, the water level sensor 7 immediately transmits the detected signal to the controller in the mounting base 8 through a high-temperature resistant and corrosion-resistant insulated wire.

[0029] Next, after receiving the signal, the controller, with its stable signal processing and control functions, immediately issues a control command, which drives the buzzer 9 on the mounting base 8 to sound an alarm through the wire, thereby alerting the staff that there is a leak at the flange connection.

[0030] Finally, when dealing with leaks, workers can directly unscrew the drain plug 10 at the lower end of the water storage pipe 6. By utilizing the detachable nature of the threaded connection, the liquid inside the water storage pipe 6 can be discharged from the drain hole, facilitating subsequent cleaning of the leaked liquid and inspection and maintenance of the flange and dome.

[0031] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
