Description

Technical Field

[0001] This utility model relates to the field of protection device technology, and in particular to a protective cover device to prevent misoperation of valve handles. Background Technology

[0002] In many sectors of today's society, valves, as key components controlling the transport and flow of various fluids, are widely used in industrial production, construction facilities, energy supply, and municipal engineering. Their importance is self-evident. Once valve operation is erroneous, it can lead to a series of serious consequences. In the industrial field, chemical plants have a complex pipeline system filled with various valves. These valves control the flow and volume of hazardous chemicals such as acids, alkalis, and toxic gases. If the valve handle is misoperated, it will cause chemical leakage, instantly disrupting the carefully maintained safe environment in the workshop. This will not only pose a direct threat to the life and health of the operators, but may also cause fires or even violent explosions, causing devastating damage to the entire plant. Similarly, in oil refineries, misoperation of valves can disrupt the crude oil processing flow, leading to production stoppages and huge economic losses. At the same time, it can also cause crude oil leakage, polluting the surrounding soil and water sources, and causing incalculable environmental damage.

[0003] A search revealed Chinese Patent Publication No. CN214579171U, which discloses a gas ball valve protection device. The device includes a back plate and a front cover, with the back plate and front cover connected to form a protective cover for the gas ball valve. A through-hole for the gas pipeline to pass through is provided through the cover. A first cavity for accommodating the gas ball valve is formed in the center of the through-hole; a second cavity for accommodating the ball valve handle is also provided inside the cover, penetrating the first cavity. In use, the back plate and front cover are fastened to the gas ball valve, completely covering and shielding the valve body and handle. Even if the protective device is accidentally touched, the valve will not open, improving safety during gas maintenance. The shape and size of the through-hole, the first cavity, and the second cavity can be designed according to the specific shape and size of the gas pipe and the ball valve to accommodate different models of gas ball valves. However, during equipment operation, pipeline vibration and accidental collisions with personnel and equipment can cause the protection to loosen and fail. Utility Model Content

[0022] As a further description of the above technical solution:

[0023] A warning label is fixedly connected to the front of the protective shell, and a nameplate is fixedly connected to the top right side of the protective cover.

[0024] Through the above technical solution: warning signs can be used to remind people not to touch the equipment, and nameplates are used to display relevant information about the equipment.

[0025] As a further description of the above technical solution:

[0026] A magnetic rubber disc is fixedly connected to the bottom of the protective shell, and the outer wall of the magnetic rubber disc is fixedly connected to the inner wall of the sealing ring.

[0027] Through the above technical solution, the magnetic rubber disc allows the protective shell to be firmly adsorbed onto the metal surface and fixedly connected to the inner wall of the sealing ring, thereby ensuring a tight bond between the protective shell and the magnetic rubber disc, preventing the intrusion of moisture and dust, and enhancing the overall sealing performance.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, when a fixed locking is required, the U-shaped block is pushed so that the short column passes through the second support ring, and then the connecting sleeve is pushed so that the connecting sleeve passes through the first support ring. Then the connecting sleeve is rotated so that the threaded groove one on the inner side of the connecting sleeve engages with the threaded groove two on the outer side of the short column, thus achieving a fixing effect. This can effectively resist external vibration and collision interference factors, ensure that the protective cover is fixed in position on the valve, and prevent the protective cover from shifting due to accidental shaking, thereby effectively preventing the valve handle from being operated incorrectly.

[0030] 2. In this utility model, when the outer shell is subjected to external pressure, the rigid support ring can provide additional structural support for the outer shell. The elastic gasket can reduce the transmission of vibration to the interior and prevent the valve handle from being damaged by severe vibration. The flexibility of the rubber ring allows it to adapt to the relative movement between the outer shell and other components to a certain extent. In addition to its anti-corrosion effect, the anti-corrosion coating can also reduce wear on the surface of the outer shell and maintain the integrity of the outer shell.
