Description

Technical Field

[0001] The invention belongs to the field of breakaway valves, and in particular relates to a semi-automatic switching structure of a breakaway valve. Background Art

[0002] The emergency breakaway valve, also known as the breakaway valve, can prevent leakage accidents caused by accidental breakage of the pipeline. It is applicable to unloading from the ship to the other side, loading and unloading of tanks on roads and railways, and other fixed and mobile fluid storage devices, such as the connection between crane pipes, fluid conveying arms and transport carriers. This device is a weak connection point in the entire transmission link. When the set conditions are met, the pipeline connection is disconnected, and the intermediate medium is self-sealed in the pipeline. The breakaway valve is divided into bolt-breaking type and rope type (ring release technology) according to the release method. It is a very commonly used technical equipment.

[0003] Chinese patent CN217874410U discloses an emergency disengagement valve for a low-temperature fluid loading and unloading arm, including an emergency disengagement valve body, wherein the first flange is fixed to the left and right sides of the emergency disengagement valve body, the second flange is fixed to the left side of the first flange on the left side, and the loading and unloading arm body is fixed to the left side of the second flange. The emergency disengagement valve for a low-temperature fluid loading and unloading arm has a sealing mechanism in which the sealing gasket and the second flange are tightly fitted to enhance the sealing performance at the connection between the first flange and the second flange, and at the same time, the sealing gasket is pushed by the first spring and the slide plate to make it fit more tightly with the second flange, thereby avoiding leakage. The limit assembly connects the emergency disengagement valve body and the loading and unloading arm body together by inserting the positioning block into the fixed block; The above design can enhance the sealing between the connecting flanges through the use of multiple groups of components to avoid leakage when the equipment is in use. However, there are certain problems with the use of the equipment. Specifically, the internal pressure of the equipment cannot be accurately detected when the equipment is running, and the staff cannot clearly observe and distinguish the internal pressure of the disengagement valve, resulting in the staff being unable to disengage the disengagement valve in time, which affects the working quality of the equipment itself and makes it impossible to accurately and stably assist the disengagement valve to disengage.

[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0021] Depend on Figure 1 , Figure 2 and Figure 3As shown, a semi-automatic switching structure of a detachable valve comprises a detachable valve body 1, a breaking ring 2 and a fixing member 3, wherein the detachable valve body 1 is composed of two groups of connecting members, a breaking ring 2 is fixedly installed between the two groups of connecting members, fixing members 3 are symmetrically fixedly installed on both sides of the detachable valve body 1, a breaking mechanism 4 is symmetrically fixedly installed inside the detachable valve body 1, the breaking mechanism 4 comprises a middle-end feeding rack 41, a receiving plate 42, a breaking assembly 43, and a connecting interface 44, the middle-end feeding rack 41 is fixedly installed with the inner wall of the detachable valve body 1, the side of the middle-end feeding rack 41 is fixedly installed with the receiving plate 42, the inside of the middle-end feeding rack 41 is fixedly installed with the breaking assembly 43, and a connecting interface 44 is provided on one side of the middle-end feeding rack 41.

[0022] During use, the device is installed on the target pipeline, and then the fixing parts 3 are used to strengthen and fix the overall components of the detachment valve body 1, and then the breaking mechanism 4 is used to stably transport the material inside the pipeline. Through the use of the receiving plate 42, the material entering the detachment valve body 1 will pass through the receiving plate 42 and enter the middle-end feeding rack 41, and then through the use of the connecting interface 44, the material passes through one group of middle-end feeding racks 41 and enters the receiving plate 42 on the other side of the detachment valve body 1. Then, the material also passes through the receiving plate 42 and the middle-end feeding rack 41, and the material is directly discharged from the other side of the detachment valve body 1. When a leak occurs in one side of the pipeline, the breaking component 43 runs quickly at this time to push the side of the turnover leak, so that the breaking ring 2 between the two groups of connecting parts is broken, and the pipeline is blocked simultaneously, making the use of the device itself more stable, thereby improving the working quality of the device itself.

[0023] By the attached Figure 4 As shown, in this embodiment, the fracture assembly 43 also includes a fixed frame 431, an electric push rod 432, a fracture sealing plate 433 and a fracture extrusion rod 434. The fixed frame 431 is fixedly installed inside the middle-end feeding rack 41, the electric push rod 432 is fixedly installed on the side of the fixed frame 431, the fracture extrusion rod 434 is fixedly installed at the output end of the electric push rod 432, the fracture sealing plate 433 is fixedly installed on the outside of the fracture extrusion rod 434, and the fracture extrusion rod 434 is slidably connected to the connecting interface 44.

[0024] During use, the electric push rod 432 is started to start, so that the broken sealing plate 433 drives the broken extrusion rod 434 to move to the other side, and the broken extrusion rod 434 passes through the connecting interface 44 to enter the middle-end feeding rack 41 on the other side, and the broken extrusion rod 434 contacts another group of broken extrusion rods 434, and the two are squeezed to make the broken ring 2 at the middle end of the valve body 1 break, completing the rapid disassembly of the pipeline, and the broken sealing plate 433 moves with the broken extrusion rod 434, and the broken sealing plate 433 will be close to the side opening of the connecting interface 44, The whole pipeline of the middle-end feeding rack 41 is closed to prevent internal material leakage, thereby ensuring the stability of the equipment during use.

[0025] By the attached Figure 5 As shown, in this embodiment, the semi-automatic switching structure of the detachment valve also includes a display mechanism 5, and the display mechanism 5 includes a spring group 51, an extrusion ring 52, an extrusion component 53 and a display component 54. The extrusion ring 52 is slidably installed inside the detachment valve body 1, and the spring group 51 is fixedly installed on the side of the extrusion ring 52. When the extrusion ring 52 slides toward the side of the breaking mechanism 4, the spring group 51 is in a force storage state, the extrusion component 53 is fixedly installed inside the breaking mechanism 4, and the display component 54 is fixedly installed on the upper surface of the detachment valve body 1.

[0026] During use, through the cooperation of the fixing part 3 and the connecting pipeline, the material inside the pipeline will enter the interior of the detachment valve body 1. At this time, the material will push and squeeze the extrusion ring 52, allowing the extrusion ring 52 to slide along the inner wall of the detachment valve body 1. At this time, the extrusion component 53 moves synchronously with the extrusion ring 52. During the movement of the extrusion ring 52, the spring group 51 handles the accumulation state. With the cooperation of the extrusion component 53 and the display component 54, the impact pressure of the material inside the pipeline can be displayed in time, which is convenient for the staff to observe in real time according to the detection data. When the material inside the pipeline leaks, due to insufficient impact pressure, the extrusion ring 52 automatically resets under the elastic action of the spring group 51, and the display component 54 automatically lowers its own height. The staff can clearly observe the internal pressure changes, which is convenient for timely manual initiation of equipment rupture.

[0027] By the attached Figure 5 As shown, in this embodiment, the extrusion assembly 53 includes a pushing extrusion rod 531, a pushing pad 532, a pushing groove 533 and a connecting pipe 534. The pushing extrusion rod 531 is fixedly installed on the side of the extrusion ring 52, and the pushing pad 532 is fixedly installed at the end of the pushing extrusion rod 531. A pushing groove 533 is opened inside the middle-end feeding rack 41. The pushing groove 533 is slidably connected with the pushing pad 532. A connecting pipe 534 is arranged between the disengagement valve body 1 and the pushing pad 532. The liquid inside the pushing groove 533 enters the display assembly 54 through the connecting pipe 534.

[0028] During use, by using the squeezing ring 52, the pushing squeezing rod 531 pushes the pushing pad 532 to move stably inside the pushing groove 533. When the pushing pad 532 moves, the rubber layer on the outside of the pushing pad 532 is used. Each time the pushing pad 532 moves, the liquid inside the pushing groove 533 will be input into the display component 54 through the connecting tube 534. Once the liquid inside the display component 54 increases, the overall height of the display component 54 will change with the change of the liquid level.

[0029] By the attached Figure 6 As shown, in this embodiment, the display component 54 includes a lifting groove 541, a rubber sliding block 542, a lifting display rod 543 and a limit block 544. The lifting groove 541 is opened inside the disengagement valve body 1, the rubber sliding block 542 is slidably installed inside the lifting groove 541, the lifting display rod 543 is fixedly installed on the top of the rubber sliding block 542, and the limit block 544 is fixedly installed on the top of the lifting display rod 543.

[0030] During use, the extrusion component 53 is used to push the liquid inside the groove 533 through the connecting tube 534 into the lifting groove 541. As the total amount of liquid inside the lifting groove 541 continues to increase, the rubber sliding block 542 continues to move upward under the action of pressure, pushing the overall height of the lifting display rod 543 and the limit block 544 to change. Afterwards, the internal pressure of the device can be quickly identified by observing the height of the lifting display rod 543 and the limit block 544, so that the device can be controlled in time according to the change in pressure.

[0031] By the attached Figure 6 As shown, in this embodiment, the lifting and displaying rod 543 is slidably connected to the detachment valve body 1, and scale grooves are equidistantly provided on both side surfaces of the lifting and displaying rod 543.

[0032] During use, the lifting display rod 543 is slidably connected to the detachable valve body 1. The lifting display rod 543 can be pushed by the rubber sliding block 542 and continuously slide up and down along the inner wall of the lifting groove 541 to adjust the height of the lifting display rod 543 extending out of the surface of the detachable valve body 1. Subsequent staff can timely reflect the internal pressure of the equipment by observing the scale groove on the side of the lifting display rod 543. Once the pressure changes significantly, it means that there is a leak in the pipeline on one side, which is convenient for the staff to control the equipment to break in time and reduce losses.

[0033] By the attached Figure 7As shown, in this embodiment, the semi-automatic switching structure of the detachment valve also includes a control mechanism 6, and the control mechanism 6 includes a rotating base 61, a rotating bracket 62 and a rotating handle 63. The rotating base 61 is fixedly installed on the surface of the detachment valve body 1, and the rotating bracket 62 is rotatably installed inside the rotating base 61. The rotating bracket 62 penetrates the rotating base 61 and enters into the detachment valve body 1. The rotating handle 63 is fixedly installed on the top of the rotating bracket 62.

[0034] During use, by holding the rotating handle 63, under the push of the staff's hand, the rotating handle 63 drives the rotating bracket 62 to rotate, providing convenience for the subsequent operation of other components inside the control mechanism 6. Once the rotation angle of the rotating bracket 62 reaches the target position, the breaking mechanism 4 will be started immediately to complete the separation and breaking of the entire equipment, reduce resource loss, realize semi-automatic switching of the equipment, and assist the stable use of the equipment.

[0035] By the attached Figure 7 As shown, in this embodiment, the control mechanism 6 also includes a first contact plate 64, a second contact plate 65 and a rotating groove 66. A rotating groove 66 is opened inside the disengagement valve body 1, and the first contact plate 64 is fixedly installed on the bottom end of the rotating bracket 62. The first contact plate 64 is rotatably connected to the rotating groove 66, and the second contact plate 65 is fixedly installed on the inner wall of the rotating groove 66.

[0036] During use, by rotating the rotating bracket 62, the overall angle of the first contact plate 64 changes until the side of the first contact plate 64 fits with the side of the second contact plate 65. Once the electrode sheets inside the first contact plate 64 and the second contact plate 65 fit together, the internal circuit can be connected. At this time, the breaking mechanism 4 will immediately enter the operating state to complete the separation and breaking of the entire equipment.

[0037] By the attached Figure 7 As shown, in this embodiment, the fixing member 3 includes a fixing ring 31, a mounting screw groove 32 and a sealing gasket 33. The fixing ring 31 is fixedly installed on the surface of the detachable valve body 1, and the fixing ring 31 has mounting screw grooves 32 equidistantly opened inside. The sealing gasket 33 is arranged inside the fixing ring 31.

[0038] During use, the fixing ring 31 and the mounting screw groove 32 are used to quickly connect the equipment to the pipeline, ensuring that the pipeline is unobstructed and assisting in the stable transportation of subsequent materials. The use of the sealing gasket 33 further strengthens the sealing when the pipeline is connected to the equipment, ensuring the stability of the equipment during operation.

[0039] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as belonging to the protection scope determined by the claims submitted for the present invention.
