Description

Technical Field

[0001] This utility model belongs to the field of thermal insulation valve technology, specifically relating to a thermal insulation valve that prevents heat loss. Background Technology

[0002] Insulated valves have excellent heat preservation and cold preservation properties, and the valve diameter is consistent with the pipe diameter. At the same time, they can effectively reduce the heat loss of the medium in the pipeline. Insulated valves are widely used in various systems such as petroleum, chemical, metallurgy, and pharmaceutical industries. They effectively reduce the heat loss of the medium in the pipeline and prevent the occurrence of phenomena such as crystallization and solidification of the medium.

[0003] The Chinese utility model patent CN218818444U, entitled "A Thermal Insulation Valve," describes a method for insulating the valve body. First, a fixing plate is pulled up. Then, a limiting plate on the surface of the housing is inserted into the limiting groove of the second housing. The fixing plate is then loosened, and the spring force resets it, causing it to be inserted into a retaining plate for fixation. When valve maintenance is required, simply pulling up the fixing plate allows for easy disassembly of the housing and the second housing. However, the patent describes a gap at the connection between the first and second housings, allowing heat from the medium in the pipeline to easily escape, resulting in insufficient insulation. Utility Model Content

[0004] The purpose of this invention is to provide a heat-insulating valve to prevent heat loss, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat-insulating valve for preventing heat loss, comprising a housing with a removable heat-insulating layer installed inside, the heat-insulating layer comprising a first heat-insulating layer and a second heat-insulating layer, the housing comprising a first housing and a second housing, the first heat-insulating layer and the second heat-insulating layer being respectively installed inside the first housing and the second housing, and a slot being provided at the edge of the first heat-insulating layer, and a locking block being provided at the edge of the second heat-insulating layer to cooperate with the slot.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6 As shown, the present invention provides the following technical solution: a heat preservation valve for preventing heat loss, comprising a housing 4 with a removable heat preservation layer 5 installed inside, the heat preservation layer 52 including a first heat preservation layer 51 and a second heat preservation layer 52, the housing 4 including a first housing 41 and a second housing 42, the first heat preservation layer 51 and the second heat preservation layer 52 being respectively installed inside the first housing 41 and the second housing 42, and a slot 511 is provided at the edge of the first heat preservation layer 51, and a locking block 521 that cooperates with the slot 511 is provided at the edge of the second heat preservation layer 52;

[0023] It also includes a valve stem 1 and a valve body 2. The valve body 2 is mounted on the housing 4, and the valve stem 1 is mounted on the valve body 2 and extends into the housing 4. The valve stem 1 and the valve body 2 cooperate to facilitate the opening and closing of the heat preservation valve.

[0024] To address the above, when using this heat-preventing insulated valve, the first insulation layer 51 is fixed to the inner wall of the first housing 41, and the second insulation layer 52 is fixed to the inner wall of the second housing 42. The connection positions of the first insulation layer 51 and the second insulation layer 52 are staggered from the connection positions of the first housing 41 and the second housing 42, thereby preventing heat from flowing out from the gap between the first housing 41 and the second housing 42 and reducing heat loss. Furthermore, the slots 511 and the blocks 521 on the first insulation layer 51 and the second insulation layer 52 allow the blocks 521 to be engaged in the slots 511, making the connection between the first insulation layer 51 and the second insulation layer 52 tighter and ensuring more stable overall performance of the insulated valve.

[0025] In addition, such as Figure 1 and Figure 2 As shown, in this utility model, both ends of the first housing 41 and the second housing 42 are equipped with mounting flanges 3. The mounting flanges 3 are sleeved on the outside of the first housing 41 and the second housing 42. The mounting flanges 3 are installed at both ends of the first housing 41 and the second housing 42 to connect the first housing 41 and the second housing 42 together to form a complete valve body. Moreover, the connection through the mounting flanges 3 makes disassembly and assembly more convenient.

[0026] Preferred, such as Figure 5As shown, connectors are installed between the two mounting flanges 3 and the first housing 41 and the second housing 42, which facilitate the installation and removal of the first housing 41 and the second housing 42 from the mounting flanges 3.

[0027] Specifically, such as Figure 5 and Figure 6 As shown, in one embodiment, regarding the above-mentioned connector:

[0028] The connector includes a first fixing block 7 and a second fixing block 8. There are two of each first fixing block 7 and the second fixing block 8. Both first fixing blocks 7 are installed on the first housing 41 and the second housing 42. The first fixing blocks 7 are provided on both sides of the first housing 41 and the second housing 42. Both second fixing blocks 8 are installed on the mounting flange 3. The second fixing blocks 8 can be connected to the two first fixing blocks 7.

[0029] The connector also includes a fixing bolt 6. Threaded holes are provided on the first fixing block 7 and the second fixing block 8. The fixing bolt 6 passes through the threaded holes. The first fixing block 7 and the second fixing block 8 are fixedly connected by the fixing bolt 6. Each first fixing block 7 is matched with a fixing bolt 6, thereby connecting with the second fixing block 8.

[0030] In response to the above, during installation, the two mounting flanges 3 are fitted onto the two ends of the first housing 41 and the second housing 42, so that the threaded holes of the first fixing block 7 and the second fixing block 8 correspond to each other. The fixing bolts 6 pass through the threaded holes, thereby connecting the first fixing block 7 and the second fixing block 8 together, so that the first housing 41 and the second housing 42 are tightly connected together, making disassembly convenient and facilitating later inspection and maintenance.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
