DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0026] See also Figure 1 - Figure 6 In this embodiment, it relates to an easy-to-install pipeline valve 71 protective cover, which is specifically used to protect the valve 71 from external factors in the industrial pipeline system, such as environmental corrosion, mechanical impact, temperature change and erosion of chemical media, and specifically includes: a cover body 1, the cover body 1 includes a first shell 2 and a second shell 3, the first shell 2 and the second shell 3 are detachably connected, and the lower edges of the first shell 2 and the second shell 3 are connected.

[0027] Specifically, in this embodiment, the first shell 2 and the second shell 3 are connected by the connecting strip 11 at the lower edge. The lower edges of the first shell 2 and the second shell 3 in this embodiment are connected by the connecting strip 11. The connecting strip 11 is made of a flexible material. The connecting strip 11 serves as a bridge between the first shell 2 and the second shell 3, so that the first shell 2 and the second shell 3 can swing around the connecting strip 11 to achieve the effect of opening and closing. When installed, the first shell 2 and the second shell 3 are in an open state, and the first shell 2 and the second shell 3 are placed under the pipeline valve 71 one after the other and lifted upward, so that the first shell 2 and the second shell 3 are located at the front and back sides of the pipeline valve 71, and the first shell 2 and the second shell 3 swing and close around the connecting strip 11, and then the first shell 2 and the second shell 3 are integrated into one body through a detachable connection and the pipeline is wrapped therein, so as to achieve the installation of the protective cover.

[0028] The detachable connection methods in this embodiment include but are not limited to the following methods and their combinations:

[0029] See also Figure 5 In this embodiment, the first shell 2 is provided with a card slot 21, and a buckle 31 is provided at a corresponding position of the second shell 3. When used, the first shell 2 and the second shell 3 are connected by the card slot 21 and the buckle 31;

[0030] The outer side of the first shell 2 of this embodiment is provided with a plurality of fixing belts 22, and buckles 23 are provided on the fixing belts 22. A buckle seat 32 is provided on the outer side of the second shell 3. When in use, the buckles 23 are buckled with the corresponding buckle seats 32 to achieve the connection between the first shell 2 and the second shell 3. The buckles 23 and the buckle seats 32 here can be replaced by Velcro.

[0031] See also Figure 6In this embodiment, the first shell 2 is provided with a lock hook 24, and the corresponding side of the second shell 3 is provided with a lock buckle 33. When in use, the lock buckle 33 is opened and the first shell 2 and the second shell 3 are closed, and the lock buckle 33 is moved to make it buckle into the lock hook 24. When disassembling, the lock hook 24 is opened and the first shell 2 and the second shell 3 are opened.

[0032] The utility model uses a detachable connection between the first shell 2 and the second shell 3. The lower edges of the first shell 2 and the second shell 3 are connected by a connecting strip 11, so that the shells can be flexibly opened and closed, which makes it easy for operators to install and remove the protective cover from bottom to top. This connection method not only improves the installation efficiency, but also facilitates the rapid removal of the protective cover when emergency maintenance of the valve 71 is required. The easy installation and removal characteristics enable operators to respond quickly to ensure the continuous operation of the pipeline system.

[0033] A first opening 12 is provided on the top of the sleeve 1, and the first opening 12 is adapted to be installed with a cover 4 covering the outside of the valve 71. In this embodiment, the sleeve 1 is composed of a first shell 2 and a second shell 3 connected together. A first opening 12 is provided on the top of the sleeve 1, and the first opening 12 is located at the connection between the valve 71 and the tee 72. The first opening 12 is hinged with the cover 4 to realize the folding of the cover 4. When the valve 71 needs to be adjusted, the cover 4 is opened, and the cover 4 is covered after the adjustment is completed. When high-temperature materials are transported in the pipeline, due to the effect of heat conduction, the temperature of the valve 71 is usually high, and the cover 4 produces a barrier effect, which protects the valve 71 and can effectively prevent the operator from being scalded, thereby ensuring a safe working environment. The cover 4 is set to be transparent and made of transparent material. The operator can directly observe the state of the valve 71 without removing the protective cover. The transparent material is usually made of PVC (polyvinyl chloride) or similar corrosion-resistant materials to ensure the acid and alkali resistance and corrosion resistance of the cover 4.

[0034] The sleeve 1 is provided with a second opening 13 and a third opening 14 on both sides. The second opening 13 and the third opening 14 are both installed with a sealing component 6. The sealing component 6 includes a sleeve 61 and a hoop 62 fastened to both ends of the sealing sleeve. The sleeve 61 acts on the flange 73 connection. The hoop 62 is located at both ends of the sealing sleeve and is used to fix and pressurize the sleeve 61, so that the inner sides of both ends of the sleeve 61 are tightly fitted with the pipeline, ensuring the sealing of the flange 73 connection, thereby improving the overall safety and reliability of the pipeline system. Figure 7The pipe sleeve 61 is formed by cutting and winding a rubber sheet (a corrosion-resistant and high-temperature-resistant material such as silicone rubber or EPDM). In this embodiment, the rubber sheet is cut into a strip shape so that it can be wound along the outer diameter of the flange 73, and the width can cover the pipes at both ends of the flange 73 and the tee 72. Before winding, adhesive strips 611 are pasted on both sides of the rubber sheet along the length direction so that they can be self-adhered after winding to form a sealing sleeve. The sealing sleeve can be made by the rubber sheet, which is convenient for obtaining materials and has a low cost.

[0035] See also Figure 8 , a protective layer 5 is bonded inside the sleeve 1, and the protective layer 5 is composed of a plurality of protective units 51. The protective layer 5 can be made of different materials as needed, such as materials that are resistant to high temperatures, corrosion-resistant or have heat-insulating properties. The protective layer 5 in this embodiment is based on a heat-insulating layer 52 (rock wool material), and a layer of high-temperature-resistant alloy layer 53 (such as nickel-based and cobalt-based alloys) is wrapped on the outside thereof, and a layer of corrosion-resistant layer 54 (epoxy resin) is coated on the outer surface of the high-temperature-resistant alloy layer 53 to adapt to different working environments and requirements. The protective layer 5 in this embodiment is attached to the sleeve 1 through a Velcro structure, and the protective layer 5 is specifically divided into a plurality of protective units 51, and the outside of each protective unit 51 is wrapped with a ring surface 55 (soft fabric) with fine annular fibers, and the inside of the sleeve 1 is composed of a hook surface 17 (hard fabric) with small hooks. When the two are pressed tightly, the hook and the ring are combined. If you want to separate them, you only need to separate them by force. Each protection unit 51 can be replaced independently through the Velcro structure. In this way, when the protection of a certain part is damaged, only the damaged unit needs to be replaced instead of the entire unit, thereby saving replacement costs.

[0036] The inner circumferences of the first opening 12, the second opening 13 and the third opening 14 are all provided with sealing strips 15, and the function of these sealing strips 15 is to ensure the sealing of the connection parts (the connection between the valve 71 and the tee 72, and the connection of the pipeline flange 73). The sealing strips 15 in this embodiment are made of EPDM (ethylene propylene rubber), which has excellent aging resistance and weather resistance, and is suitable for various environments such as indoors and outdoors.

[0037] The casing 1 is provided with a through hole 16. In this embodiment, the through hole 16 is provided at the bottom of the casing 1 (at the joint of the lower edges of the first shell 2 and the second shell 3), so that air inside and outside the casing 1 can circulate, and the casing 1 can be prevented from being damaged due to excessive expansion of the gas inside the casing 1. In addition, when the temperature outside the casing 1 decreases, the water vapor inside the casing 1 condenses into water, which accumulates and flows downward and is finally discharged through the through hole 16, which helps to maintain the dryness and ventilation of the internal environment of the casing 1, and effectively protects the three-way 72 equipped with the valve 71.

[0038] The above contents described in this specification are merely examples of the present utility model. Those skilled in the art of the present utility model may make various modifications or additions to the specific embodiments described, or replace them in similar ways, as long as they do not deviate from the contents of the present utility model specification or exceed the scope defined in the claims, they shall all fall within the protection scope of the present utility model.
