Description

Technical Field

[0001] This utility model relates to a compensator, and more specifically, to a pipeline compensator. Background Technology

[0002] Pipeline compensators, also known as expansion joints or expansion valves, are mainly used to compensate for the thermal expansion and contraction of pipelines caused by temperature changes. If the pipeline cannot expand or contract freely when the temperature changes, thermal stress will be generated in the pipeline. This stress must be considered in pipeline design, otherwise it may lead to pipeline rupture and affect normal production. As an important component of pipeline engineering, compensators play an important role in ensuring the long-term normal operation of pipelines.

[0003] The applicant previously filed a patent application (publication number: CN222992480U) regarding an easy-to-install pipe compensator. This design allows for flexible adjustment of the positioning block's position by pulling a ring-shaped lever and rotating the connecting pipe. However, in practical applications, we have found the following drawbacks: because the first spring is initially compressed, the operator needs to apply significant force when pulling the ring-shaped lever; insufficient force results in incomplete pulling, directly hindering the normal rotation of the connecting pipe and thus affecting the overall smoothness of operation. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pipe compensator that can be easily connected and disassembled.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pipeline compensator, comprising a compensating body, wherein both ends of the compensating body are provided with connecting discs and connecting heads, the connecting heads are detachably installed on the connecting discs, and the connecting head includes a connecting column, a movable sleeve, and a spring assembly, wherein the movable sleeve is slidably connected to the outside of the connecting column through the spring assembly;

[0006] The movable sleeve is provided with positioning blocks and limiting blocks arranged circumferentially, and the positioning blocks and limiting blocks are arranged vertically along the radial direction of the movable sleeve.

[0007] Both the positioning block and the limiting block include a positioning part and a guide part arranged vertically, and the guide part is provided with a guide slope.

[0008] The present invention is further configured such that the guide portion is arranged in a right-angled trapezoidal structure.

[0009] The present invention is further configured such that: the inner wall of the connecting plate is provided with an annular groove, the upper end of the annular groove is provided with an opening, the lower end of the annular groove is provided with a positioning hole, and the bottom of the positioning hole is provided with a limiting slope.

[0010] The present invention is further configured such that: the opening, positioning hole, positioning block and limiting block are each provided in two sets.

[0011] The present invention is further configured such that: the movable sleeve includes an upper connecting ring, a lower connecting ring, and a connecting rod assembly, wherein two sets of connecting rod assemblies are provided and are symmetrically connected between the upper connecting ring and the lower connecting ring respectively.

[0012] The present invention is further configured such that: the spring assembly includes a fixed base and a spring body, the fixed base is fixedly installed on the connecting column, and the spring body is installed inside the fixed base;

[0013] The connecting rod assembly includes a first connecting rod, a second connecting rod, and a linkage plate. The first and second connecting rods are both installed vertically through the fixed base. The linkage plate is connected to the first and second connecting rods. The lower end of the spring body abuts against the linkage plate, and the upper end abuts against the fixed base.

[0014] The present invention is further configured such that: an adjusting rod is screwed to the upper end of the fixed base, and an adjusting plate is provided at the lower end of the adjusting rod; the adjusting rod is used to control the raising and lowering of the adjusting plate.

[0015] The adjusting plate is provided with through holes for the first connecting rod and the second connecting rod to pass through;

[0016] The upper end of the spring body is abutted against the adjusting plate.

[0017] The present invention is further configured such that: a spring post is provided at the lower end of the adjusting plate, an adjusting port for the spring post to pass through is provided in the middle of the linkage plate, and the spring body is sleeved on the spring post.

[0018] In summary, this utility model has the following beneficial effects: Utilizing the design of the upper and lower positioning and guiding parts, the position of the moving sleeve can be appropriately controlled during the pulling process. Under the following two conditions, rotating the moving sleeve can achieve the effect of separating the positioning block, limiting block, and connecting plate: Condition 1: When pulled to the desired position, both the positioning and guiding parts separate from the positioning hole and opening, thus satisfying the rotation requirement; Condition 2: When pulled to an incomplete position, the positioning part separates from the positioning hole and opening, while the guiding part remains at the position of the positioning hole and opening. In this case, the separation can be achieved through rotation and the cooperation of the guide slope.

[0019] This structural improvement makes the range of applicable positions for the movable sleeve wider and more convenient to use. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] Reference Figures 1 to 3 As shown, in order to achieve the above objectives, the present invention provides the following technical solution: a pipeline compensator, including a compensation body 1, with a connecting plate 2 and a connector 3 at both ends of the compensation body 1, the connector 3 being detachably installed on the connecting plate 2, the connector 3 including a connecting column 31, a movable sleeve 32 and a spring assembly 33, the movable sleeve 32 being slidably connected to the outside of the connecting column 31 through the spring assembly 33;

[0026] The movable sleeve 32 is provided with positioning blocks 34 and limiting blocks 35 arranged along its circumference, and the positioning blocks 34 and limiting blocks 35 are arranged vertically along the radial direction of the movable sleeve 32.

[0027] Both the positioning block 34 and the limiting block 35 include a positioning part 351 and a guide part 352 arranged vertically, and the guide part 352 is provided with a guide slope.

[0028] The present invention is further configured such that: the inner wall of the connecting plate 2 is provided with an annular groove 21, the upper end of the annular groove 21 is provided with an opening 22, the lower end of the annular groove 21 is provided with a positioning hole 23, and the bottom of the positioning hole 23 is provided with a limiting slope.

[0029] The design of this utility model utilizes the positioning part 351 and the guide part 352 arranged vertically to appropriately control the position of the moving sleeve 32 during the pulling process. Under the following two conditions, the positioning block 34, the limiting block 35 and the connecting plate 2 can be separated by rotating the moving sleeve 32: Condition 1: When pulled to the end, both the positioning part 351 and the guide part 352 are separated from the positioning hole 23 and the opening 22, which can well meet the rotation requirements; Condition 2: When pulled to the end, the positioning part 351 is separated from the positioning hole 23 and the opening 22, while the guide part 352 is still located at the position of the positioning hole 23 and the opening 22. In this case, the separation effect of the two can be achieved by rotation and the cooperation of the guide slope.

[0030] In summary, the structural improvements make the pulling position of the movable sleeve 32 more applicable and more convenient to use.

[0031] The present invention is further configured such that the guide portion 352 is arranged in a right-angled trapezoidal structure. This trapezoidal structure design, along with the corresponding structure in the preferred positioning hole 23, ensures both secure fixing and ease of assembly and disassembly.

[0032] This utility model is further configured such that two sets of opening 22, positioning hole 23, positioning block 34, and limiting block 35 are provided. This structural design can improve the stability during connection.

[0033] The present invention is further configured such that: the movable sleeve 32 includes an upper connecting ring 4, a lower connecting ring 41, and a connecting rod group 42, wherein there are two sets of connecting rod groups 42, which are symmetrically connected between the upper connecting ring 4 and the lower connecting ring 41 respectively.

[0034] The present invention is further configured such that: the spring assembly 33 includes a fixing seat 331 and a spring body 332, the fixing seat 331 is fixedly installed on the connecting column 31, and the spring body 332 is installed inside the fixing seat 331;

[0039] The upper end of the spring body 332 is set to abut against the adjusting plate 51.

[0040] The design of this structure allows the adjustment rod 5 to change the spatial position between the adjustment plate 51 and the linkage plate 45, thereby adjusting the tension on one side of the spring body 332 and changing the degree of compression of the spring body 332.

[0041] It can change the degree of compression of the spring body 332 in a wider range of application environments, thereby changing the degree of clamping force.

[0042] The present invention is further configured such that: a spring post 53 is provided at the lower end of the adjusting plate 51, an adjusting port 46 for the spring post 53 to pass through is provided in the middle of the linkage plate 45, and the spring body 332 is sleeved on the spring post 53.
