Description

Technical Field

[0001] This utility model relates to the field of thermal insulation jacketed valve technology, specifically a thermal insulation jacketed valve for preventing crystallization of pipeline media. Background Technology

[0002] In pipeline transportation systems, temperature control of the medium inside the pipeline is one of the key factors to ensure normal system operation and medium flow. Especially in pipelines transporting easily crystallizing media, once the medium temperature drops below its crystallization point, it will cause the medium to crystallize inside the pipeline, leading to serious problems such as pipeline blockage, reduced flow, or even system shutdown. This will not only affect production efficiency and increase maintenance costs, but may also damage equipment and shorten its service life.

[0003] Traditional pipe insulation methods primarily rely on wrapping the outside of the pipe with insulation materials such as rock wool and glass wool to reduce heat loss. However, this method has several limitations. First, the insulation effect of traditional insulation materials is affected by various factors such as material properties, construction techniques, and environmental conditions, making it difficult to maintain a stable temperature of the medium inside the pipe over a long period. Second, for existing pipe systems, adding or replacing insulation materials often requires complex disassembly and reinstallation work, increasing construction difficulty and cost. Furthermore, traditional insulation methods cannot provide precise temperature control for specific areas of the pipe and are insufficient to provide effective protection for areas prone to crystallization. Utility Model Content

[0004] The purpose of this invention is to provide a heat-insulating jacketed valve that prevents crystallization of pipeline media, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat-insulating jacketed valve for preventing crystallization of pipeline media, comprising a valve body, wherein an installation mechanism is provided on the surface of the valve body, and a fixing mechanism is provided inside the installation mechanism; The installation mechanism includes a first jacket and a second jacket, which are symmetrically arranged on the surface of the valve body. Arc-shaped limiting strips are symmetrically fixed to the inner walls of the first jacket and the second jacket. Arc-shaped limiting grooves corresponding to the arc-shaped limiting strips are symmetrically opened on the surface of the valve body. L-shaped insert plates are symmetrically fixed to the surface of the first jacket, and fixing blocks are symmetrically fixed to the surface of the second jacket. Slots are opened on the front of the four fixing blocks.

[0006] Preferably, the inner walls of the first and second jackets are in contact with the surface of the valve body, and the arc-shaped limiting strip and arc-shaped limiting groove limit the first and second jackets to prevent them from rotating.

[0007] Preferably, the L-shaped insert plate is inserted into the slot from the front and back.

[0008] Preferably, the fixing mechanism includes a fixing frame, which is fixedly connected to the surface of the fixing block on the side away from the second sleeve. The fixing frame on the side away from the second sleeve is provided with an internally threaded cylinder, and the internally threaded cylinder is internally threaded with a bolt. A washer is sleeved on the surface of the bolt, and a limit plug is fixedly connected to the other end of the bolt. Limiting holes corresponding to the limit plugs are opened on one side of the four L-shaped insert plates.

[0009] Preferably, the fixing bracket has a hole on the side away from the second jacket that matches the outer wall of the internal threaded cylinder, and the surface of the internal threaded cylinder is penetrated and fixedly connected to the hole.

[0010] Preferably, the fixing block has a hole on the side away from the second sleeve that matches the limiting rod, and the limiting rod is slidably connected to the hole through the surface of the limiting rod.

[0011] Preferably, the limiting rod is inserted into the limiting hole.

[0012] Compared with the prior art, this utility model provides a heat-insulating jacketed valve for preventing crystallization of pipeline media, which has the following beneficial effects: 1. This insulation jacketed valve, which prevents crystallization of pipeline media, has an installation mechanism that precisely matches the arc-shaped limiting strip with the arc-shaped limiting groove on the valve body surface. This instantly limits the circumferential movement of the first and second jackets, effectively preventing the jackets from rotating or shifting during installation. Workers do not need to repeatedly adjust the jacket positions and can directly attach the two jackets to the valve body, significantly shortening the initial assembly time. It is especially suitable for batch valve insulation retrofit scenarios.

[0013] 2. In this heat-insulating jacketed valve that prevents crystallization of pipeline media, the fixing mechanism features a threaded connection between the internal threaded cylinder and the bolt, which is matched with the insertion and locking of the limiting rod and the limiting hole of the L-shaped insert plate. After the bolt is tightened, the limiting rod extends into the limiting hole, effectively resisting the influence of external forces such as pipeline vibration and media flow impact. This avoids jacket displacement caused by loosening of the threads during long-term use, solving the industry pain point of easy loosening of traditional single thread fixing.

[0018] This utility model provides the following technical solution: Example 1 Please see Figure 1-3 This utility model provides a technical solution: a heat-insulating jacketed valve for preventing crystallization of pipeline medium, including a valve body 1, an installation mechanism 2 provided on the surface of the valve body 1, and a fixing mechanism 3 provided inside the installation mechanism 2; The mounting mechanism 2 includes a first jacket 21 and a second jacket 22. The first jacket 21 and the second jacket 22 are symmetrically arranged on the surface of the valve body 1. The inner walls of the first jacket 21 and the second jacket 22 are symmetrically fixedly connected to the left and right sides of the inner walls of the second jacket 22. The surface of the valve body 1 is symmetrically provided with arc-shaped limiting grooves 24 corresponding to the arc-shaped limiting strips 23. The first jacket 21 is symmetrically fixedly connected to the top, bottom, left and right sides of the first jacket 21. The second jacket 22 is symmetrically fixedly connected to the top, bottom, left and right sides of the second jacket 22. The four fixing blocks 26 are provided with slots 27 on their front sides.

[0019] The inner walls of the first jacket 21 and the second jacket 22 are in contact with the surface of the valve body 1. The arc-shaped limiting strip 23 and the arc-shaped limiting groove 24 limit the first jacket 21 and the second jacket 22 so that they do not rotate.

[0020] The L-shaped insert plate 25 is inserted into the slot 27 from the front and back.

[0021] Example 2 Please see Figure 4-5 Furthermore, based on Embodiment 1, a fixing mechanism 3 is obtained.

[0022] The fixing mechanism 3 includes a fixing frame 31, which is fixedly connected to the surface of the fixing block 26 on the side away from the second clamp 22. An internal threaded cylinder 32 is provided on the side of the fixing frame 31 away from the second clamp 22. A bolt 33 is internally threaded to the internal threaded cylinder 32. A washer 34 is sleeved on the surface of the bolt 33. A limit plug 35 is fixedly connected to the other end of the bolt 33. Limiting holes 36 corresponding to the limit plug 35 are opened on one side of the four L-shaped insert plates 25.

[0023] The fixing bracket 31 has a hole on the side away from the second jacket 22 that matches the outer wall of the internal threaded cylinder 32, and the surface of the internal threaded cylinder 32 is penetrated and fixedly connected to the hole.

[0024] The fixing block 26 has a hole on the side away from the second clamp 22 that matches the limiting rod 35, and the limiting rod 35 is connected to the hole by sliding up and down through the surface of the hole.

[0025] The limiting rod 35 is inserted into the limiting hole 36.

[0026] In actual operation, when using this device, when installing the first jacket 21 and the second jacket 22, first align the arc-shaped limiting strips 23 on the inner walls of the two jackets with the pre-set arc-shaped limiting grooves 24 on the surface of the valve body 1, and then fit the jackets against the valve body 1 along the direction of the limiting grooves. Since the shape and size of the arc-shaped limiting strips 23 and the arc-shaped limiting grooves 24 are perfectly matched, the circumferential rotation of the jackets around the valve body 1 can be directly restricted, ensuring that the two jackets are always in the pre-set position of symmetrically wrapping the valve from front to back, laying a precise foundation for subsequent assembly. After the arc-shaped limiting strips 23 are fully embedded in the arc-shaped limiting grooves 24, push the first jacket 21 and the second jacket 22 together. The sleeves 22 are brought closer together, so that the L-shaped insert plate 25 on the surface of the first sleeve 21 is inserted into the slot 27 on the front of the fixing block 26 of the second sleeve 22. The insertion and engagement of the L-shaped insert plate 25 and the slot 27 can achieve axial positioning of the two sleeves, preventing the sleeves from shifting along the length of the valve. At the same time, it makes the inner walls of the two sleeves completely fit the surface of the valve body 1, initially forming a sealed frame that encloses the valve. After the sleeves are initially positioned, they are reinforced by the fixing mechanism 3. The fixing bracket 31 is pre-fixed on the side of the fixing block 26 away from the second sleeve 22, and the hole opened on the fixing bracket 31 matches the outer wall of the internal threaded cylinder 32. The internal threaded cylinder 32 passes through and is fixed. With the bolt 33 inserted into the hole, the operator passes the bolt 33 through the washer 34 and screws it into the internal threaded cylinder 32. The axial force generated by the thread engagement makes the fixing bracket 31 and the fixing block 26 fit tightly together, providing a basic fixing force for the jacket. As the bolt 33 is continuously tightened, the limiting insert 35 at the other end of the bolt 33 will simultaneously pass through the preset hole on the fixing block 26 and finally insert into the limiting insert hole 36 on one side of the L-shaped insert plate 25. The insertion and engagement of the limiting insert 35 and the limiting insert hole 36 can limit the reverse rotation of the bolt 33 caused by pipeline vibration and medium flow impact, forming a dual fixing structure of thread fastening and pin locking. To completely prevent the jackets from loosening during long-term use, after installation, positioning, and locking, the first jacket 21 and the second jacket 22 completely enclose the valve body 1, and there are no obvious gaps at the joint of the two jackets or at the contact point between the jackets and the valve body 1, forming a complete sealed and heat-insulating space. This space can block the direct heat transfer between the valve body 1 and the external environment. When a crystallizing medium is transported in the pipeline, if the medium needs to maintain a specific temperature to avoid crystallization, the sealed space can reduce the loss of heat from the medium to the outside. If the outside temperature is too low, it can also prevent the low temperature from being conducted to the internal medium through the valve, ensuring that the medium temperature is stable above the crystallization threshold.
