Description

Technical Field

[0001] This application relates to the field of valve structure, and more specifically, to a ball valve transport device and an upper-mounted cryogenic hard-seal ball valve. Background Technology

[0002] Valves are key control components in the field of industrial fluid control, and top-loading ball valves are an important type of product within this category. For example... Figure 1 As shown, a top-entry ball valve generally includes a valve body 500, a valve core 510 housed within the valve body 500, a valve cover 520 connected to the top of the valve body 500, a valve stem 530 connected to the valve cover 520, and an actuator 540 connected to the top of the valve stem 530. Furthermore, a valve neck 550 is integrally formed on the top surface of the valve cover 520, providing protection to the upper outer circumference of the valve stem 530 and preventing direct exposure. A drip plate 560 is fixedly fitted onto the valve neck 550. Flanges 570 are integrally formed at both ends of the valve body 500. Because the core components, such as the valve core 510 and valve stem 530, can be installed and maintained from the top of the valve body without requiring complete valve disassembly, top-entry ball valves offer significant advantages in fields such as oil, natural gas, and cryogenic engineering. Compared to other ball valve structures such as side-mounted and bottom-mounted, the top-mounted design not only simplifies the later maintenance process but also effectively reduces downtime and lowers maintenance costs in industrial production. Therefore, it is increasingly used in scenarios where equipment reliability and maintenance efficiency are highly demanding.

[0003] However, the valve neck lacks additional protection during long-distance transportation and is prone to collisions with the transport container and other equipment, which can cause deformation or damage to the valve neck. This not only affects the integrity of the appearance but may also damage the protective seal of the valve stem, increasing the cost of later maintenance. Summary of the Invention

[0004] The purpose of this application is to provide a ball valve transport device and an upper-mounted cryogenic hard-seal ball valve, which can support the ball valve during transport while protecting the valve neck, the top of the ball valve and both ends of the ball valve, so as to prevent the valve neck and valve body of the ball valve from being collided, deformed or damaged during transport.

[0005] This application is implemented as follows: This application provides a ball valve transport device, comprising: The support plate has multiple casters at the bottom and is used to connect and support the ball valve at the top. The base plate is rotatably fitted onto the valve neck of the ball valve and its bottom is supported on the top surface of the valve cover of the ball valve. A pair of limiting plates are symmetrically hinged to the top surface of the substrate. The two limiting plates are configured to be rotatable to be arranged vertically to enclose a receiving cavity for accommodating the valve neck, or arranged horizontally to be respectively attached to the top surface of the substrate. A pair of protective plates are hinged to both ends of the base plate and can be moved along the length of the base plate. The two protective plates are configured to be rotatable to be vertically arranged downwards and detachably connected to both ends of the support plate, or vertically arranged upwards on both sides of the valve neck. The flexible protective curtain is detachably connected at both ends to the top of two vertically arranged protective panels.

[0006] In some alternative implementations, the two limiting plates are each provided with a receiving groove, and when the two limiting plates are rotated to a vertical arrangement, the two receiving grooves respectively engage with both sides of the valve neck.

[0007] In some alternative implementations, the ends of the two limiting plates are respectively provided with elastic rubber pads, and when the two limiting plates are rotated to a vertical arrangement, the two rubber pads press against the bottom surface of the drip plate fixedly sleeved on the valve neck.

[0008] In some alternative implementations, each of the two protective plates is provided with a limiting groove, which, when rotated to a downward vertical arrangement, engages with the flanges at both ends of the ball valve.

[0009] In some alternative implementations, the two ends of the substrate are connected to two protective plates by at least two first telescopic rods, and the two protective plates are respectively provided with upper slots; when the two limiting plates are rotated to a horizontal arrangement and the two protective plates are rotated to an upward vertical arrangement, the ends of the two limiting plates are respectively engaged with the two upper slots.

[0010] In some alternative implementations, a second telescopic rod that can rotate along a vertical plane is hinged to each side of both ends of the support plate, and positioning grooves are provided at the four corners of the bottom surface of the substrate. Each second telescopic rod is configured to be able to be inserted into the positioning groove to support the bottom surface of the substrate when rotated to a vertical position.

[0011] In some alternative implementations, each of the two protective plates is provided with two lower slots. When the two protective plates are rotated to a vertically facing downward position, the second telescopic rods on both sides of the support plate are rotated to a horizontal position and respectively engaged in a corresponding lower slot.

[0012] In some alternative implementations, the substrate has a clearance hole for the valve neck to pass through, the inner wall of the clearance hole has a plurality of placement grooves arranged circumferentially, the outer wall of the valve neck has a plurality of grooves arranged circumferentially, each placement groove has a hemispherical locking block and a compression spring at both ends that presses against the locking block and the inner wall of the placement groove, respectively. When the substrate rotates around the valve neck axis to a preset angle, the placement groove and the groove are aligned one by one, and the compression spring pushes the locking block into the corresponding groove.

[0013] In some alternative implementations, the protective panel has at least two hanging rings at the end furthest from the substrate, and the protective curtain has hooks at both ends that are connected to each hanging ring in a one-to-one correspondence.

[0014] This application also provides an upper-mounted cryogenic hard-seal ball valve, which includes the aforementioned ball valve transport device and ball valve. The ball valve includes a valve body connected to the top of a support plate, a valve core disposed within the valve body, a valve cover connected to the top of the valve body, a valve stem connected to the valve cover, and an actuator connected to the top of the valve stem. The top of the valve cover is provided with a valve neck sleeved on the valve stem.

[0015] The beneficial effects of this application are as follows: The ball valve transport device and the upper-mounted cryogenic hard-seal ball valve provided by this application can protect the valve neck by hinged two limiting plates on the top of the base plate sleeved on the ball valve neck. The two limiting plates can be rotated to a vertical arrangement to form a receiving cavity to accommodate the valve neck. The protective plates hinged at both ends of the base plate can be rotated to a vertical arrangement and detachably connected to both ends of the protective curtain. Thus, the upper part of the ball valve is wrapped and protected by the two protective plates and the protective curtain. When needed, the two protective plates can also be rotated to a downward vertical arrangement and detachably connected to both ends of the support plate to protect both ends of the ball valve. Thus, the ball valve supported on the support plate is protected in multiple directions. Attached Figure Description

[0026] The following detailed description of the features and performance of the ball valve transport device and the cryogenic hard-seal ball valve of this application, in conjunction with embodiments, provides further insight into their respective characteristics and performance.

[0027] This application provides an embodiment of a cryogenic hard-seal ball valve, which includes a ball valve and a ball valve transport device for transporting the ball valve, such as... Figure 1 As shown, the ball valve includes a valve body 500, a valve core 510 disposed within the valve body 500, a valve cover 520 connected to the top of the valve body 500, a valve stem 530 connected to the valve cover 520, and an actuator 540 connected to the top of the valve stem 530. The top of the valve cover 520 is provided with a valve neck 550 sleeved on the valve stem 530, and a drip plate 560 is fixedly sleeved on the valve neck 550. Flanges 570 are integrally formed at the openings at both ends of the valve body 500.

[0028] Among them, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, the ball valve transport device includes a support plate 100 with movable wheels 110 connected to the four corners of the bottom, a base plate 200 rotatably fitted onto the valve neck 550, two limiting plates 210 symmetrically hinged to the top surface of the base plate 200, a pair of protective plates 300 and a flexible protective curtain 400. The valve body 500 is connected to the top surface of the support plate 100. The bottom of the base plate 200 is supported on the top surface of the valve cover 520. The two limiting plates 210 are respectively provided with receiving grooves 230. When the two limiting plates 210 are rotated to a vertical position, the two receiving grooves 230 surround to form a receiving cavity 220 for receiving the valve neck 550. When the two limiting plates 210 are rotated to a horizontal position, they respectively adhere to the top surface of the base plate 200. The ends of the two limiting plates 210 away from the base plate 200 are respectively provided with elastic rubber pads 240. When the two limiting plates 210 are rotated to a vertical position, the two rubber pads 240 respectively press against the bottom surface of the drip plate 560.

[0029] The base plate 200 has a clearance hole 260 in the middle for the valve neck 550 to pass through. The inner wall of the clearance hole 260 has four placement grooves 270 arranged circumferentially. The outer wall of the valve neck has four grooves 280 that correspond one-to-one with the grooves 280. The included angle between two adjacent placement grooves 270 and two adjacent grooves 280 is 90 degrees. Each placement groove 270 has a hemispherical locking block 290 and a compression spring 291 at both ends that presses against the locking block 290 and the inner wall of the placement groove 270, respectively. When the base plate 200 rotates around the valve neck axis to a preset angle, the placement grooves 270 and the grooves 280 are aligned one-to-one, and the compression spring 291 pushes the locking block 290 into the corresponding groove 280.

[0030] Two first telescopic rods 250, which can extend and retract along their length, are respectively connected to both ends of the substrate 200. Two protective plates 300 are respectively hinged to the two first telescopic rods 250 at both ends of the substrate 200 in a vertical plane. Each of the two protective plates 300 has an upper slot 320 on the top of one side, and lower slots 330 at both ends of the top of the other side. Each of the two protective plates 300 has a limiting groove 310 in the middle of the other side. When the two limiting plates 210 are rotated to a horizontal position and the two protective plates 300 are rotated to an upward-facing vertical position, the ends of the two limiting plates 210 are respectively engaged with the two upper slots 320. When the protective plate 300 is rotated to a vertically downward position, the two limiting grooves 310 are respectively engaged with the flanges 570 at both ends of the valve body 500. A second telescopic rod 120 that can rotate along a vertical plane is hinged to both sides of the support plate 100. The second telescopic rod 120 can extend and retract along its length. The four corners of the bottom surface of the base plate 200 are respectively provided with positioning grooves 201. When each second telescopic rod 120 is rotated to a vertical position, it is inserted into the respective positioning groove 201 to support the bottom surface of the base plate 200. When the two protective plates 300 are rotated to a vertically downward position, each second telescopic rod 120 is engaged with a corresponding lower slot 330 when rotated to a horizontal position.

[0031] The protective plate 300 is provided with two hanging rings 340 at one end away from the base plate 200. The two ends of the protective curtain 400 are respectively provided with hooks 410 that are connected to each hanging ring 340 in a one-to-one correspondence. The two ends of the protective curtain 400 are respectively connected to the corresponding hanging rings 340 on the top of the two vertically arranged protective plates 300 through the hooks 410.

[0032] The cryogenic hard-seal ball valve provided in this embodiment is connected to and supported by a support plate 100. A base plate 200 is rotatably fitted onto the valve neck 550 and supported on the valve cover 520 of the valve body 500. Two limiting plates 210 are hinged to the top surface of the base plate 200. The top surfaces of the two limiting plates 210 are respectively provided with receiving grooves 230. The two receiving grooves 230 can be rotated along the vertical plane towards each other to be vertically arranged and respectively engage with both sides of the valve neck 550. Thus, the receiving grooves 230 of the two limiting plates 210 enclose and form a receiving cavity 220 to accommodate the valve neck 550, thereby protecting the valve neck 550 from external impact damage. At the same time, the ends of the two limiting plates 210 away from the base plate 200 are respectively provided with elastic rubber pads 240. When the two limiting plates 210 rotate and engage with both sides of the valve neck 550, the two rubber pads 240 respectively press against the bottom surface of the drip plate 560 to achieve elastic fixation.

[0033] At both ends of the base plate 200, two first telescopic rods 250, which are extendable along their length, are hinged to protective plates 300 that can rotate along a vertical plane. The user can adjust the position of the two protective plates 300 by extending and retracting the first telescopic rods 250 to adapt to the protection of the ball valve supported by the support plate 100. At this time, the user can rotate the two protective plates 300 to face downwards and vertically, and make the limiting grooves 310 on one side of the two protective plates 300 respectively engage with the flanges 570 at both ends of the valve body 500 for protection. In this way, the protective plates 300 can be used to seal the openings on the flanges 570 at both ends of the valve body 500, reducing the operating pressure. To mitigate the possibility of impurities entering the valve body 500 during transport, the user can rotate the second telescopic rods 120, which are hinged to both ends of the support plate 100, to a horizontal position and extend each second telescopic rod 120 along its length. This allows the four second telescopic rods 120 to be locked into the two corresponding lower slots 330 at the bottom ends of one side of the two protective plates 300, thus detachably connecting and fixing the two protective plates 300 to the four second telescopic rods 120 hinged to both ends of the support plate 100. This allows the support plate 100, the two protective plates 300, and the base plate 200 to surround and protect the valve body 500 connected to the top of the support plate 100.

[0034] The user can also rotate the two limiting plates 210 in a vertical plane away from each other until they are horizontally aligned with the top surface of the substrate 200, and rotate the two protective plates 300 to be vertically aligned upwards, so that the ends of the two limiting plates 210 are respectively engaged in the upper slots 320 provided on the other side of the two protective plates 300 for fixation. Then, the two ends of the protective curtain 400 are respectively connected to the corresponding hanging rings 340 on the top of the two vertically aligned protective plates 300 via hooks 410. The protective curtain 400, the two protective plates 300 and the substrate 200 are used to surround and protect the valve neck 550, valve stem 530 and actuator 540 on the top of the valve body 500.

[0035] The substrate 200 has a clearance hole 260 in the middle for the valve neck 550 to pass through. The inner wall of the clearance hole 260 and the outer wall of the valve neck 550 are positioned by a locking block 290 located in the placement groove 270 and the corresponding groove 280, and a compression spring 291 at both ends that presses against the inner wall of the locking block 290 and the placement groove 270 respectively. This allows the user to rotate the substrate 200 around the valve neck axis to a preset angle so that the placement groove 270 and the groove 280 are aligned one by one, and then the compression spring 291 pushes the locking block 290 into the corresponding groove 280 to elastically connect the substrate 200 and the valve neck 550. In addition, the four corners of the bottom surface of the substrate 200 are provided with positioning grooves 201. The user can also rotate the four second telescopic rods 120 to a vertical position and insert them into the positioning grooves 201 to support the bottom surface of the substrate 200, thereby using the four second telescopic rods 120 to stably support the substrate 200.

The detailed description of the embodiments of this application is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
