[0026] Example

[0027] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a fully enclosed, assembled rubber-lined valve bracket, including:

[0028] Valve unit 100,

[0029] The protective unit 200 is fixedly installed on the top of the valve unit 100 by bolts, including a support 210, a top plate 220 fixedly installed on the top of the support 210, a circular plate 230 fixedly installed on the top of the top plate 220, a through hole 240 opened in the center of the inner cavity of the circular plate 230, and a diagonal tie 250 welded to the inner cavity of the support 210.

[0030] The protective unit 200 is integrated with the valve unit 100 by bolts. The support 210, top plate 220, circular plate 230 and diagonal brace 250 form a closed frame, which effectively prevents external dust, slag and other impurities from entering the valve body 110 and protects the sealing surface of the rubber valve seat. The through hole 240 provides a channel for the valve stem of the cylinder 140. The four diagonal braces 250 are arranged at an angle to enhance the impact resistance and rigidity of the support, which is suitable for high vibration conditions and significantly extends the service life of the valve unit 100.

[0031] Specifically, the protective unit 200 also includes a base 260 fixedly installed at the bottom of the support 210, a groove 270 opened on the outside of the base 260, and a disassembly assembly 280 set on the outside of the support 210. Threaded holes are opened on the outside of both the support 210 and the base 260. The support 210, the top plate 220, the circular plate 230, the diagonal brace 250 and the base 260 are all made by an integral welding process. There are four diagonal braces 250, and they are all evenly distributed at the angle of inclination at the bend of the angle steel of the support 210.

[0032] The base 260 and the support 210 are connected by an integrated welding process to ensure the overall structural stability; the groove 270 facilitates alignment adjustment during installation and improves assembly accuracy; the threaded holes on the outside of the support 210 and the base 260 support modular expansion; the diagonal braces 250 are evenly distributed at the bends of the angle steel to further disperse stress, prevent cracking at the welded parts, and adapt to high-pressure media environments such as slurry and coal slurry.

[0033] Furthermore, the disassembly assembly 280 includes protective plates 281 located on the front and rear sides of the support 210, side plates 282 fixedly installed on both sides of the support 210, and fastening screws 283 threaded on the outside of the protective plates 281. The protective plates 281 are designed to be detachable, and the fastening screws 283 are threadedly connected to the outside of the support 210.

[0034] The detachable protective plate 281 and the side plate 282 are fixed by fastening screws 283, which facilitates quick disassembly and maintenance and reduces downtime. The protective plate 281 covers the front and rear sides of the support 210 to form a fully enclosed protection. At the same time, the threaded connection ensures the sealing performance and prevents impurities from entering from the gaps. This design is particularly suitable for working conditions that require frequent maintenance, taking into account both protection and ease of operation.

[0035] Preferably, the valve unit 100 further includes a valve body 110 fixedly installed at the bottom of the support 210, a valve sleeve 120 fixedly installed on the outside of the valve body 110, a gate 130 movably installed in the inner cavity of the valve body 110, and a cylinder 140 fixedly installed on the top of the circular plate 230. The output end of the cylinder 140 is provided with a valve stem, which is fixedly connected to the outside of the gate 130 through the protective unit 200.

[0036] The valve body 110 is fixed to the bottom of the support 210. The gate 130 is driven by the cylinder 140 to achieve precise lifting control. The cylinder 140 is fixed to the top of the circular plate 230. The valve stem passes through the protective unit 200 and connects to the gate 130. The fully enclosed structure protects the driving components from corrosion. The valve sleeve 120 enhances the sealing performance of the valve body 110. The movable design of the gate 130 ensures flexible response in media such as sewage and slurry, improving interception efficiency and sealing reliability.

[0037] During use, the cylinder 140 applies downward force through the valve stem, causing the gate 130 to move vertically within the valve body 110. At this time, the fully enclosed structure of the protective unit 200 ensures that the driving components are not affected by the external environment. The gate 130 and the valve sleeve 120 form a tight fit, and the diagonal tie 250 support structure effectively absorbs the vibration generated by the medium pressure. The groove 270 design ensures the precise alignment of the sealing surface. The protective plate 281 can be removed by loosening the fastening screw 283 to expose the internal components for inspection. The threaded hole of the base 260 supports quick replacement of damaged parts. The entire process is completed in a closed environment, which not only ensures operational reliability but also achieves convenient maintenance.

[0038] In summary, the modular combination of the protective unit 200, using an integrated welding process, and the valve unit 100 forms a completely enclosed protective system, effectively isolating pollutants such as dust and slag, and protecting the rubber sealing surface. The inclined arrangement of the four diagonal tie rods 250, combined with the stress dispersion design at the angle steel bends, significantly improves the impact resistance and rigidity of the overall structure. The modular design of the detachable component 280 ensures both the tightness of the protection and ease of maintenance and repair. It can automatically switch between manual and manual rotation components, ensuring reliable sealing of the gate 130 in harsh media environments. It is suitable for high-pollution and high-vibration working conditions such as metallurgy and coal mining, and can extend the service life of the valve unit 100 and reduce maintenance costs.
