Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to an integrated heat-dissipating top-mounted valve cover assembly. Background Technology

[0002] In industrial pipeline systems, valves, as key equipment for controlling fluid transport, are widely used in the transportation of high-temperature and high-pressure media in industries such as petroleum, chemicals, and power. Especially in high-temperature media transport lines, the stability and reliability of valves directly affect the operational efficiency and safety of the entire system.

[0003] However, existing valves have limited heat dissipation performance under high-temperature conditions, which can easily lead to aging, deformation, or even failure of internal seals in long-term high-temperature environments, affecting the overall performance and service life of the valve.

[0004] When existing valves transport high-temperature media, such as steam and hot oil, heat is conducted through the valve stem to the valve cover area, causing the sealing packing (such as graphite and rubber) to age, carbonize, or deform due to continuous heating, resulting in media leakage. The lack of an active forced heat dissipation mechanism leads to low valve stability. Therefore, an integrated heat dissipation top-mounted valve cover assembly is proposed. Utility Model Content

[0005] To address the problems in the prior art, this utility model provides an integrated heat-dissipating top-mounted valve cover assembly.

[0006] The technical solution adopted by this utility model to solve its technical problem is an integrated heat dissipation type top-mounted valve cover assembly, including a valve cover, a valve body is installed at the bottom of the valve cover by bolts, a drive motor is installed at the top of the valve cover, a bushing for protecting the drive shaft of the drive motor is integrally connected between the valve cover and the housing of the drive motor, and heat dissipation fins are provided at equal distances from the bottom to the top of the outer periphery of the bushing, and the heat dissipation fins are integrally connected with the bushing.

[0007] An air guide sleeve is provided on the outer periphery of the heat sink, and the air guide sleeve is fixed to the valve cover.

[0008] By adopting the above technical solution, a heat dissipation integrated valve cover assembly composed of valve cover, heat sink and air guide shell is provided for the high temperature medium conveying line. This ensures the stability of the valve when it is put into use in the high temperature medium conveying line. The heat sink increases the heat dissipation surface area of ​​the valve cover and realizes active heat dissipation, thereby improving the stability of the valve body internal sealing mechanism and other components in the high temperature conveying line environment for a long time.

[0009] The valve cover assembly and drive motor bushing are integrated into one design, reducing the heat conduction path; the heat sink directly covers the drive shaft area, protecting the motor bearings and internal valve seals such as valve stem packing, extending the life of critical components.

[0010] Specifically, the air guide shell is provided with openings on both sides, with one opening on one side being an air inlet and the other opening on the other side being an air outlet.

[0011] The exhaust port side of the air guide shell is covered with a mounting plate, and an exhaust fan is mounted on the mounting plate.

[0012] By adopting the above technical solution, the heat dissipation surface area is greatly increased by the equidistant heat dissipation fins on the outer periphery of the bushing. Combined with the forced convection of the exhaust fan inside the air guide shell, the high temperature inside the valve body is quickly discharged, effectively avoiding the aging, deformation or failure of the seals caused by high temperature media such as steam and hot oil.

[0013] Specifically, bolt holes are provided at the inner corner of the exhaust port of the air guide shell, and the corner of the mounting plate is fixed by bolts and bolt holes.

[0014] Specifically, a rectangular frame is fixedly glued to the outer periphery of the air inlet of the air guide shell. A pull-out groove is provided at the inner periphery of the rectangular frame. A pull-out opening is provided through one side of the rectangular frame. A rectangular inner frame is provided inside the rectangular frame. A metal filter screen is fixedly provided on the inner periphery of the rectangular inner frame. The rectangular inner frame is inserted into the pull-out groove through the pull-out opening. The metal filter screen of the rectangular inner frame separates the inside and outside of the air guide shell.

[0015] Specifically, a pull-out opening extends from one side of the rectangular inner frame and is provided with a pull tab. A corresponding magnet is embedded in the end of the pull-out slot away from the pull tab and the end of the rectangular inner frame away from the pull tab.

[0016] By adopting the above technical solution, the removable metal filter design and the magnetically fixed rectangular inner frame allow for quick disassembly and cleaning of dust and oil, preventing blockage of the heat dissipation duct, ensuring long-term heat dissipation efficiency, and reducing downtime maintenance costs.

[0017] The beneficial effects of this utility model are as follows: The assembly, consisting of a valve cover, heat sink, and air guide sleeve, provides a heat-dissipating, integrated valve cover assembly for high-temperature media conveying lines. This ensures the stability of the valve when used in high-temperature media conveying lines. The heat sink increases the heat dissipation surface area of ​​the valve cover and achieves active heat dissipation, improving the stability and lifespan of internal sealing mechanisms and other components in the high-temperature conveying line environment. This solves the problem of low valve stability caused by heat conduction through the valve stem to the valve cover area when conveying high-temperature media such as steam and hot oil, leading to aging, carbonization, or deformation of the sealing packing due to continuous heating. The lack of an active forced heat dissipation mechanism further addresses this issue. This utility model reduces the heat conduction path by integrating the valve cover assembly with the drive motor's bushing, protecting the motor bearings and internal valve seals. The combination of the heat sink and fan forms a forced convection mechanism, significantly improving heat dissipation efficiency. The removable metal filter screen, combined with a magnetically fixed rectangular inner frame, allows for quick disassembly and cleaning of dust and oil, preventing blockage of the cooling duct. The implementation of the above technical solutions ensures the efficient operation of the valves in high-temperature environments, providing reliable technical support for high-temperature medium transport lines.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

A valve body 1 is bolted to the bottom of the valve cover 2. A drive motor is mounted on the top of the valve cover 2. A bushing 21 for protecting the drive shaft of the drive motor is integrally connected between the valve cover 2 and the housing of the drive motor. Heat sinks 22 are provided at equal distances from the bottom to the top of the outer periphery of the bushing 21. The heat sinks 22 are integrally connected to the bushing 21.

[0028] An air guide sleeve 3 is provided on the outer periphery of the heat sink 22, and the air guide sleeve 3 is fixed on the valve cover 2.

[0029] The present invention also includes that the air guide shell 3 is provided with openings on both sides, and the opening on one side of the air guide shell 3 is an air inlet and the opening on the other side is an air outlet.

[0030] The exhaust port side of the air guide sleeve 3 is covered with an installation plate 32, and an exhaust fan 33 is installed on the installation plate 32.

[0031] During use, the equidistant heat sinks 22 on the outer periphery of the bushing 21 greatly increase the heat dissipation surface area. Combined with the forced convection of the exhaust fan 33 inside the air guide shell 3, the high temperature inside the valve body is quickly discharged, effectively avoiding the aging, deformation or failure of the seals caused by high temperature media such as steam and hot oil.

[0032] This utility model also includes a bolt hole 31 provided at the inner circumferential corner of the exhaust port of the air guide shell 3, and the corner of the mounting plate 32 is fixed by bolts to the bolt hole 31.

[0033] This utility model also includes a rectangular frame 34 fixedly glued to the outer periphery of the air inlet of the air guide shell 3. A pull-out groove 35 is provided at the inner periphery edge of the rectangular frame 34. A pull-out opening 36 is provided through one side of the rectangular frame 34. A rectangular inner frame 37 is provided inside the rectangular frame 34. A metal filter screen 38 is fixedly provided on the inner periphery of the rectangular inner frame 37. The rectangular inner frame 37 is inserted into the pull-out groove 35 through the pull-out opening 36. The metal filter screen 38 of the rectangular inner frame 37 separates the inside and outside of the air guide shell 3.

[0034] The present invention also includes a pull-out opening 36 extending from one side of the rectangular inner frame 37, and a pull buckle 39 provided thereon. A corresponding magnet 4 is embedded in the end of the pull-out groove 35 away from the pull buckle 39 and the end face of the rectangular inner frame 37 away from the pull buckle 39.

[0035] When in use, the design of the pull-out metal filter screen 38 and the magnetically fixed rectangular inner frame 37 allow for quick disassembly and cleaning of dust and oil, preventing blockage of the heat dissipation air duct, ensuring long-term heat dissipation efficiency, and reducing downtime maintenance costs.

[0036] In use, the bushing 21 with heat sink 22 is integrally cast / welded to the top of the valve cover 2 to ensure that the heat sink 22 is evenly distributed along the outer periphery of the bushing. The air guide shell 3 covers the outer periphery of the heat sink 22 and the lower end is fixed to the surface of the valve cover 2 to form a guide air duct. The mounting plate 32 with exhaust fan 33 is assembled to the exhaust port of the air guide shell 3, and the power supply component in the work site provides power to the exhaust fan 33. Then, the rectangular inner frame 37 with metal filter screen 38 is inserted into the rectangular frame 34 of the air inlet of the air guide shell 3. The inner side of the rectangular frame 34 and the rectangular inner frame 37 are magnetically fixed based on magnets. With the setting of the pull buckle 39, it is easy for personnel to quickly pull out the rectangular inner frame 37 to clean the metal filter screen 38.

[0037] When the valve cover is assembled with the valve body to form an integral valve, and the valve is put into use in a high-temperature medium conveying line, the exhaust fan 33 is turned on. The exhaust fan 33 draws air from the air guide shell 3, and the air is filtered by the metal filter screen 38. After the air carries away the temperature of the heat sink 22 and the bushing 21, it is discharged through the exhaust fan 33, thereby achieving forced convection cooling of the valve cover area.
