Abstract
Description
Technical Field
[0001] This utility model belongs to the field of valve technology, and in particular relates to a valve insulation and protection cover. Background Technology
[0002] In industrial and daily life, pipelines are commonly used to transport heat-generating substances. To prevent heat loss, valves are often wrapped with insulation layers, and then a metal protective layer is wrapped around the insulation. While this method provides insulation, it is inconvenient to install, maintain, and disassemble, and can only be used once. Furthermore, the insulation materials used in these layers are generally not heat-resistant. If used in high-temperature fluid pipelines, the insulation material may lose its insulating properties due to excessively high pipeline temperatures, potentially even causing a fire.
[0003] Existing patent CN202349509U discloses a high-temperature resistant valve insulation and protection cover, which consists of two interlocking semi-cavity covers with connecting flanges at their edges. The semi-cavity covers, from the outside in, consist of a fiberglass shell, a high-temperature resistant adhesive layer, and a high-temperature resistant insulation layer; the high-temperature resistant insulation layer is made of aluminum silicate fiber felt insulation material. The fiberglass shell is molded, and its internal cavity size and shape are adapted to the valve's shape. This utility model uses a two-semi-cavity cover structure and employs a high-temperature resistant adhesive layer and high-temperature resistant insulation material, which facilitates installation and disassembly, prevents the insulation material from losing its insulation effect due to excessively high fluid pipeline temperatures, and avoids potential fire hazards. It is suitable for insulation and protection of valves in high-temperature fluid pipelines. However, when high-temperature fluid flows through the pipeline, the temperature difference between the inside and outside of the pipeline causes water vapor to form on the outer wall of the pipeline, and fluid may overflow at the valve. This water vapor corrodes the surface of the protective cover, damaging it and reducing its service life. Utility Model Content
[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a valve insulation and protection cover. A waterproof layer is installed inside the valve insulation and protection cover to prevent water vapor from corroding the surface of the cover and to improve the service life of the cover.
[0005] In view of this, the present invention provides a valve heat insulation and protective cover, characterized in that it includes a valve body, in which a high-temperature fluid flows, and the valve body is provided with:
[0006] A protective device is installed on the valve body and is used to protect the valve body.
[0007] A waterproof device is installed inside the protective device, and the waterproof device is used to prevent water vapor on the valve body from contacting the protective device.
[0008] A heat preservation device is installed inside the waterproof device and is used to maintain the temperature inside the valve.
[0009] In this technical solution, the protective device and the heat preservation device are installed on the outside of the valve body, which can protect and insulate the valve body. When the high-temperature fluid flows inside the valve body, some water vapor will remain on the valve body. Installing a waterproof device on the valve body can prevent water vapor from corroding the valve's protective device and extend the service life of the valve body.
[0010] Furthermore, the heat preservation device includes:
[0011] An insulation shell is disposed outside the valve body and is connected to the valve body through the insulation shell;
[0012] A heat insulation shell is disposed inside the insulation shell. The inner diameter of the heat insulation shell is adapted to the valve body. The heat insulation shell is detachably connected to the outer surface of the valve body. The heat insulation shell includes a high-temperature resistant layer and a heat insulation layer, with the heat insulation layer disposed inside the high-temperature resistant layer.
[0013] In this technical solution, the insulation shell can be made of aluminum silicate fiber felt insulation material, the high-temperature resistant layer can be made of high-temperature resistant mica board, and the heat insulation layer can be made of composite silicate board. The valve body transports high-temperature fluid. In order to prevent heat loss, an insulation shell is set on the outside of the valve body. During the flow of high-temperature fluid, the temperature will be conducted to the valve body, causing the temperature of the valve body to rise. The insulation shell and heat insulation shell can isolate the high temperature inside the valve body from the outside, preventing users from being burned when touching the valve body, thus improving the safety of the valve body.
[0014] Furthermore, the insulation shell includes a front shell and a rear shell, which are detachably connected to the front and rear surfaces of the valve body, respectively. A connecting rod is provided on the side of the front shell near the valve body, and four connecting rods are provided. The rear shell is provided with a slot corresponding to the connecting rod, and the front shell and the rear shell are engaged and connected.
[0015] In this technical solution, moving the front shell causes the connecting rod to leave the slot of the rear shell, thereby separating the front and rear shells, making it easier to remove the insulation device from the valve body and replace the insulation device.
[0016] Furthermore, a sealing strip is provided at the connection between the front shell and the rear shell, and the sealing strip is fixedly connected to the front shell and the rear shell. The sealing strip is made of high temperature resistant material.
[0017] In this technical solution, the sealing strip is made of metal rubber. Installing the sealing strip at the connection between the front shell and the rear shell can better insulate heat and improve the thermal insulation performance.
[0018] Furthermore, the waterproofing device is detachably mounted on the valve body. The waterproofing device includes a waterproof layer, which is fixedly mounted on the outside of the insulation shell and is detachably connected to the inner wall of the insulation shell.
[0019] In this technical solution, the waterproof layer can be made of polystyrene foam plastic. The waterproof layer is located between the heat insulation shell and the thermal insulation shell to prevent water vapor corrosion on the valve body and to give the valve body good waterproof performance.
[0020] Furthermore, a sealing ring is provided at the connection between the heat insulation shell and the valve body. The sealing ring is fixedly connected to the outer surface of the valve body and is made of a high-temperature resistant material.
[0021] In this technical solution, the sealing ring is made of metal rubber. The sealing ring improves the sealing performance of the heat insulation shell, prevents water vapor from leaking out of the waterproof device, and improves the waterproof performance of the valve body.
[0022] Furthermore, a handle is provided on the upper end of the valve body, and the handle is rotatably connected to the valve.
[0023] Furthermore, the protective device includes:
[0024] The outer casing is detachably disposed at both ends of the valve body and is connected through the valve body. The size of the outer casing is larger than the diameter of the valve body.
[0025] A protective shell is vertically installed inside the outer shell. The protective shell has a downward opening. The inner diameter of the protective shell is adapted to the diameter of the valve body. A U-shaped groove is provided at the lower end of the protective shell. The width of the U-shaped groove is adapted to the diameter of the valve body.
[0026] In this technical solution, the outer shell is set on the outside of the valve body to protect the entire valve body and prevent the valve body from being damaged in case of accidents. The U-shaped groove of the protective shell can be engaged with the valve body to fix the protective shell on the valve body. The protective shell is used to protect the handle to prevent problems with the handle from causing failure of the valve body's conveying system and to improve the service life of the valve body.
[0027] Furthermore, a shock-absorbing pad is fixedly installed inside the protective shell. The size of the shock-absorbing pad is adapted to the diameter of the handle. The lower surface of the shock-absorbing pad is in contact with the handle. The shock-absorbing pad is made of an elastic, flexible material.
[0028] In this technical solution, the shock-absorbing pad can be made of sponge. The shock-absorbing pad is used to further protect the handle and prevent it from being damaged by sudden vibrations, and can provide a certain amount of cushioning.
[0029] Furthermore, a cylinder is fixedly installed on the upper inner wall of the outer shell, and the output end of the cylinder is connected to the upper surface of the protective shell.
[0030] In this technical solution, the cylinder is used to control the lifting and lowering of the protective shell, so as to facilitate the disassembly of the protective shell.
[0031] The beneficial effects of this utility model are:
[0032] 1. This utility model enables the valve body to transport high-temperature fluid. In order to prevent heat loss, an insulation shell is set on the outside of the valve body. During the flow of high-temperature fluid, the temperature will be conducted to the valve body, causing the temperature of the valve body to rise. The insulation shell and heat insulation shell can isolate the high temperature inside the valve body from the outside, preventing users from being burned when touching the valve body, thus improving the safety of the valve body.
[0033] 2. This utility model realizes a waterproof layer between the heat insulation shell and the thermal insulation shell, which is a protective device to prevent water vapor corrosion on the valve body, and can give the valve body good waterproof performance.
[0034] 3. This utility model achieves the outer shell being set on the outside of the valve body so that the outer shell can protect the entire valve body, preventing the valve body from being damaged in case of accidents. The U-shaped groove of the protective shell can be locked onto the valve body, so that the protective shell is fixed to the valve body. The protective shell is used to protect the handle, so that problems with the handle will prevent the valve body's conveying system from malfunctioning, thereby improving the service life of the valve body.
