Description

Technical Field

[0001] This utility model relates to the field of modular valve cover protection frames, specifically a modular structure and modular valve cover protection frame. Background Technology

[0002] Valve cover protectors, also known as valve protective covers, come in various forms and designs to suit different application requirements. One common type is the modular design. Modular valve cover protectors are industrial components used to protect valve covers. They are typically assembled from multiple parts, covering the valve cover to provide protection against impacts and damage. Modular valve cover protectors are usually made of metal or plastic and undergo special processing to achieve a certain level of strength and structural stability.

[0003] In the existing technology, the modular valve cover protection frame is usually composed of two shells with the same shape. The two shells are fitted over the two ends of the valve cover to cover the valve cover, while the through holes are reserved to expose the valve stem and pipe. Then, bolts are inserted into the reserved screw holes to fix the two halves of the shell onto the valve cover. This installation method is quick and simple, and it is convenient to disassemble the valve cover for maintenance and repair later.

[0004] However, since valve cover protectors are made of metal and have a certain value, and many valves that require valve cover protectors are located in public places such as underground parking garages in residential areas, there is a risk that they may be removed and stolen.
