Abstract
Description
Technical Field
[0001] This utility model relates to the field of instrument valve technology, and specifically to an instrument valve with a protective structure. Background Technology
[0002] An instrument valve is a pipeline accessory used to control the flow of a conveying medium. Its core function is to achieve precise control of the medium by changing the cross-sectional area of the passage and the direction of medium flow. Instrument valves are generally used in conjunction with related instruments for monitoring the flow status of the medium. Instrument valves are widely used in fluid control systems in industries such as petroleum, chemical, power, pharmaceutical, and food, and are an indispensable key component in industrial automation and process control.
[0003] The instruments in existing instrument valves are usually directly exposed to the external environment. When the instruments are directly exposed to the production site, they are not only susceptible to external impacts, but also dust accumulates on the instrument surface or enters the interior, causing internal components to jam or be damaged, thus reducing the service life of the instruments.
[0004] For example, the instrument regulating valve with lockable designation disclosed in patent CN211423530U lacks a protective structure. In the production site, equipment, tools, or personnel may accidentally collide with the exposed instrument, causing the instrument casing to crack, the pointer to bend, or internal components to loosen, resulting in inaccurate instrument readings or complete failure. This affects the monitoring and control of the production process. Furthermore, corrosive gases or liquids may be present in the production site. If the exposed instrument comes into direct contact with these corrosive gases, the casing will rust due to prolonged exposure, thus accelerating the aging of the instrument.
[0005] Therefore, it is necessary to invent an instrument valve with a protective structure to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide an instrument valve with a protective structure, which solves the problem of reduced instrument lifespan due to the lack of a protective structure.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an instrument valve with a protective structure, comprising a valve body, a valve stem vertically disposed at the top of the valve body, a turntable disposed at the top of the valve stem, an instrument panel disposed at one end of the valve body, and a protective cover disposed outside the instrument panel. The protective cover is made of aluminum alloy material and consists of a first shell and a second shell, both of which are designed to be detachable. A circular transparent shell is embedded in the front wall of the second shell. An elastic deformation sealing strip is disposed on the contact surface at the connection between the first shell and the second shell. Sealing gaskets are disposed at the connection ends of the first shell, the second shell and the valve body. A reinforcing mechanism is disposed around the other side of the first shell and the second shell.
[0008] Preferably, the transparent shell is made of high-strength tempered glass and its surface is coated with a scratch-resistant coating. High-strength tempered glass has high strength and impact resistance, which can effectively resist these accidental collisions, prevent the transparent shell from breaking, and thus protect the internal instrument panel from damage.
[0009] Preferably, the second housing has a plug rod on the side close to the first housing, and the first housing has a matching slot on the side that contacts the plug rod. When the first housing and the second housing are assembled, the cooperation between the plug rod and the slot can play a preliminary positioning role.
[0010] Preferably, the first and second housings are connected by fixing screws at their upper and lower ends on one side, and fixing nuts are threaded onto the fixing screws. By tightening the fixing nuts, the first and second housings can be firmly fixed together, thereby enhancing the connection strength between them.
[0011] Preferably, the reinforcement mechanism includes a first reinforcement plate and a second reinforcement plate. The second reinforcement plate is located on the first shell, and the first reinforcement plate is located on the second shell. The first and second reinforcement plates can further improve the stability of the connection between the first shell and the second shell.
[0012] Preferably, the side of the first reinforcing plate close to the second reinforcing plate is provided with a plug-in block, and the side of the second reinforcing plate in contact with the plug-in block is provided with a matching plug-in groove. The cooperation between the plug-in block and the plug-in groove is similar to the plug rod and slot in the shell connection structure. Its function is to reposition the reinforcing plates during assembly to ensure that the first and second reinforcing plates can be accurately aligned.
[0013] Preferably, the reinforcement mechanism further includes a bearing seat located on the side wall of the second reinforcement plate, and a limiting plate is hinged to the bearing seat. The design of the limiting plate can further limit the relative displacement between the first and second reinforcement plates.
[0014] Preferably, the limiting plate has a reinforcing bolt that extends through and into the interior of the first reinforcing plate. The contact position between the first reinforcing plate and the reinforcing bolt is provided with a screw hole that matches it. The matching of the reinforcing bolt and the screw hole is a more secure fixing method, which can tightly connect the first reinforcing plate and the second reinforcing plate together to form a more robust whole.
[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0016] 1. This utility model provides a protective cover to the outside of the instrument panel, which, by utilizing its all-around wrapping characteristics, constructs a tight and reliable protective system for the instrument panel. It can effectively resist external physical impacts and corrosive environments, building a solid protective barrier for the instrument panel and preventing damage from accidental collisions, scratches, or chemical corrosion, thereby significantly extending the service life of the instrument panel.
[0017] 2. The protective cover in this utility model consists of a first shell and a second shell, both of which adopt a detachable structure design. This design allows operators to easily open the protective cover when the instrument panel needs to be inspected, maintained or replaced, providing convenience for the overall disassembly and assembly of the protective cover, greatly improving work efficiency and reducing maintenance time and costs.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0026] This utility model provides, for example Figure 1-5 The instrument valve shown includes a valve body 1, a valve stem 2 vertically mounted on the top of the valve body 1, a turntable 3 mounted on the top of the valve stem 2, an instrument panel 4 mounted on one end of the valve body 1, and a protective cover 5 mounted on the outside of the instrument panel 4. The protective cover 5 is made of aluminum alloy and consists of a first housing 501 and a second housing 502, which are designed to be detachable. A circular transparent shell 503 is embedded in the front wall of the second housing 502. Sealing gaskets are provided at the connection ends of the first housing 501, the second housing 502 and the valve body 1. A reinforcing mechanism 10 is provided around the other side of the first housing 501 and the second housing 502. The transparent shell 503 is made of high-strength tempered glass and its surface is coated with an anti-scratch coating.
[0027] In this embodiment, the protective cover 5 is made of aluminum alloy, which has high strength and good corrosion resistance, effectively resisting external physical impacts and preventing the instrument panel 4 from being damaged by external forces. The corrosion resistance of aluminum alloy also ensures that the protective cover 5 can be used for a long time in harsh industrial environments without being corroded, thus providing reliable protection for the instrument panel 4. In addition, the transparent shell 503 made of high-strength tempered glass has excellent impact resistance and can withstand a certain amount of external impact without breaking, protecting the internal instrument panel 4 from damage. At the same time, the scratch-resistant coating can prevent scratches from forming on the surface of the transparent shell 503, keeping it clear and transparent, allowing operators to clearly observe the readings on the instrument panel 4 at any time. This ensures that the instrument panel 4 is always in a safe working environment and guarantees its service life.
[0028] An elastically deformable sealing strip is provided at the contact surface of the connection between housing 1 501 and housing 2 502. A plug rod 6 is provided on the side of housing 2 502 near housing 1 501. A matching slot 7 is provided on the side of housing 1 501 that contacts the plug rod 6. Fixing screws 8 pass through the upper and lower ends of one side of housing 1 501 and housing 2 502, and fixing nuts 9 are threaded onto the fixing screws 8. The reinforcement mechanism 10 includes a first reinforcement plate 1001 and a second reinforcement plate 1002. The second reinforcement plate 1002 is located on housing 1 501, and the first reinforcement plate 1001 is located on housing 2 502. A plug-in block 1003 is provided on the side of the first reinforcing plate 1001 that is close to the second reinforcing plate 1002. A matching plug-in groove 1004 is provided on the side of the second reinforcing plate 1002 that contacts the plug-in block 1003. The reinforcing mechanism 10 also includes a bearing 1005, which is located on the side wall of the second reinforcing plate 1002. A limiting plate 1006 is hinged on the bearing 1005. A reinforcing bolt 1007 passes through the limiting plate 1006 and extends into the interior of the first reinforcing plate 1001. A screw hole 1008 that matches the contact position between the first reinforcing plate 1001 and the reinforcing bolt 1007 is provided.
[0029] In this embodiment, the insert rod 6 on the second housing 502 and the slot 7 on the first housing 501 cooperate to provide initial positioning during the assembly of the first housing 501 and the second housing 502, enabling operators to quickly and accurately align the two, improving assembly efficiency and accuracy. Furthermore, the combination of the fixing screw 8 and the fixing nut 9 provides a reliable connection; by tightening the fixing nut 9, the first housing 501 and the second housing 502 can be firmly fixed together, enhancing the connection strength between them. Additionally, the insert block 1003 on the first reinforcing plate 1001 and the second reinforcing plate... The insertion slot 1004 on 1002 plays a role in repositioning during the assembly of the reinforcing plate. Finally, by passing the reinforcing bolt 1007 through the limiting plate 1006 and screwing it into the screw hole 1008 inside the first reinforcing plate 1001, the first reinforcing plate 1001 and the second reinforcing plate 1002 can be tightly connected together to form a more robust whole. In addition, the elastic deformation sealing strip begins to play its role, filling the tiny gap at the connection between the two and providing a preliminary sealing effect, thereby further improving the stability and robustness of the protective cover 5 and enhancing its ability to protect the instrument panel 4.
