Description

Technical Field

[0001] The utility model relates to the technical field of fluorine-lined ball valves, in particular to a thermal insulation sealing compensation fluorine-lined ball valve. Background Art

[0002] Fluorine-lined ball valves utilize a sphere with a circular through-hole as the opening and closing element. The sphere rotates with the valve stem around the centerline of the valve body to open and close the valve. A special molding process creates a dense and precise sealing surface. The sphere and valve stem are cast as one piece, eliminating the possibility of the valve stem being ejected from the pressure-bearing component due to pressure fluctuations, fundamentally ensuring safety during operation. The all-plastic lining provides resistance to the most corrosive media. Fluorine-lined ball valves are professionally designed to control the opening and closing of various highly corrosive media. They are widely used in the petroleum, chemical, dyeing, pesticide, acid and alkali production industries, and are the ideal choice for corrosion-resistant valves. Fluorine-lined ball valves are available in various drive modes, including manual, worm gear, pneumatic, and electric.

[0003] Patent specification CN221323514U discloses a double-seal ball valve comprising a valve body with a stem groove formed therein. A valve stem is inserted and rotatably disposed within the stem groove to control the opening and closing of the valve body. A first seal and a second seal are sleeved on the stem. The first seal is resistant to high temperatures, while the second seal is resistant to low temperatures. Both seals abut against the inner wall of the stem groove to form a seal. This application has the effect of expanding the applicable environmental range of the ball valve.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: the above device is not convenient for sealing and compensating the water storage outside the valve core during use, and it is also not convenient for replacing the sealing gasket. If the seal is inevitably aged due to corrosion during long-term use, it is easy to cause cost loss. Therefore, further improvement is needed. Utility Model Content

[0005] The utility model provides a heat-insulating sealing compensation fluorine-lined ball valve, which solves the problem in the related art that the sealing gasket is inconvenient to replace and maintain.

[0006] The technical solution of the utility model is as follows:

[0007] The thermal insulation sealing compensation fluorine-lined ball valve includes a connecting valve seat, flanges are fixedly connected to the outside of the connecting valve seat on both sides, a connecting valve core is provided inside the connecting valve seat, a connecting handle is fixedly connected to the top of the connecting valve core, connecting grooves are provided on both sides of the top of the connecting valve seat, fitting pads are provided on both sides of the outside of the connecting valve core, embedded shells are embedded in the two fitting pads, threaded rods are provided inside the two embedded shells, the two threaded rods are respectively connected to the two embedded shells by threads, and the tops of the two threaded rods are fixedly connected to fixed plates.

[0008] Preferably, the top of the connecting handle extends to the outside of the connecting valve seat, and the connecting handle and the connecting valve seat are connected via a bearing.

[0009] Preferably, the two fitting pads are both made of rubber, and the inner sides of the two fitting pads are in contact with the outer sides of the connecting valve core respectively.

[0010] Preferably, the two fixing plates are respectively arranged inside the two connecting grooves, and the outer surfaces of the fixing plates are in contact with the inside of the connecting grooves.

[0011] Preferably, a mounting plate is fixedly installed on the top of the two fixing plates, and a fixed clamping plate is fixedly installed on one side of the outer side of the connecting valve seat.

[0012] Preferably, a threaded shell is fixedly connected to one side of the outer portion of the fixed clamping plate, and the shape of the threaded shell is set to be zigzag.

[0013] Preferably, a threaded column is provided inside the threaded shell, and the threaded column is connected to the threaded shell through a thread.

[0014] Preferably, the interior of the threaded column is connected to a limiting rod via a bearing, and the bottom of the limiting rod is fixedly connected to the top of the mounting plate.

[0015] The working principle and beneficial effects of the utility model are as follows:

[0016] In the present invention, when the fitting gasket completely enters the interior of the connecting valve seat and fits with the outer surface of the connecting valve core, the connecting valve core can be sealed by the fitting gasket. When the connecting handle drives the connecting valve core to rotate and seal, the water flow will be blocked by the connection between the fitting gasket and the connecting valve core, preventing water from leaking from the gap between the connecting valve core and the connecting valve seat, thereby achieving a sealing compensation effect.

[0017] In the utility model, the limit rod body will synchronously drive the mounting plate to move during the upward movement, and the mounting plate will synchronously drive the fixing plate and the threaded rod to move upward during the movement, and the threaded rod will synchronously drive the embedded shell and the fitting gasket to leave the interior of the connection valve seat during the movement. Then the staff will rotate the embedded shell, and the embedded shell will gradually separate from the threaded rod. After that, the staff can replace or maintain the fitting gasket and the embedded shell, which solves the problem of inconvenience in replacing and maintaining the sealing gasket.

[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0025] like Figures 1 to 3As shown, this embodiment proposes an insulated sealing compensating fluorine-lined ball valve, including a connecting valve seat 1, flanges 2 are fixedly connected to the outside of the connecting valve seat 1 on both sides, a connecting valve core 3 is provided inside the connecting valve seat 1, a connecting handle 4 is fixedly connected to the top of the connecting valve core 3, connecting grooves 5 are provided on both sides of the top of the connecting valve seat 1, fitting pads 6 are provided on both sides of the outside of the connecting valve core 3, embedded shells 7 are embedded in the two fitting pads 6, threaded rods 8 are provided inside the two embedded shells 7, the two threaded rods 8 are respectively connected to the two embedded shells 7 by threads, and the tops of the two threaded rods 8 are fixedly connected to fixed plates 9.

[0026] In this embodiment, the top of the connecting handle 4 extends to the outside of the connecting valve seat 1, and the connecting handle 4 and the connecting valve seat 1 are connected via a bearing, so that the connecting handle 4 can drive the connecting valve seat 1 to rotate.

[0027] In this embodiment, the two fitting pads 6 are both made of rubber, and the inner sides of the two fitting pads 6 are in contact with the outer sides of the connecting valve core 3 respectively, which can facilitate the movement of the fitting pads 6.

[0028] In this embodiment, the two fixing plates 9 are respectively arranged inside the two connecting grooves 5 , and the outer surfaces of the fixing plates 9 are in contact with the inside of the connecting grooves 5 , which can facilitate the movement of the fixing plates 9 .

[0029] During use, when it is necessary to seal the connecting valve seat 1, the staff first needs to insert the fitting gasket 6 into the interior of the connecting groove 5. During this process, the fixing plate 9 is moved downward. The fixing plate 9 will drive the threaded rod 8 to move downward. The threaded rod 8 will synchronously drive the embedded shell 7 to move downward during the downward movement. The embedded shell 7 will synchronously drive the fitting gasket 6 to move downward during the downward movement. When the fitting gasket 6 completely enters the interior of the connecting valve seat 1 and fits with the outer surface of the connecting valve core 3, the sealing of the connecting valve core 3 can be achieved through the fitting gasket 6. When water needs to be transported through the interior of the connecting valve seat 1, the staff will rotate the connecting handle 4. The connecting handle 4 will synchronously drive the connecting valve core 3 to rotate during the rotation. The connecting valve core 3 will fit and rotate with the inside of the fitting gasket 6 during the rotation. Then the water can flow out through the through hole in the middle of the connecting valve core 3. When the connecting handle 4 drives the connecting valve core 3 to rotate again, the water will be blocked by the connection between the fitting gasket 6 and the connecting valve core 3, thereby achieving the effect of sealing compensation. Example 2

[0030] like Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that a mounting plate 10 is fixedly installed on the top of the two fixing plates 9, and a fixed clamping plate 11 is fixedly installed on the outer side of the valve seat 1, which can facilitate the fixed connection of the fixed clamping plate 11.

[0031] In this embodiment, a threaded shell 12 is fixedly connected to one side of the outer portion of the fixed clamping plate 11 . The threaded shell 12 is zigzag in shape, which facilitates the fixed connection of the threaded shell 12 .

[0032] In this embodiment, a threaded column 13 is provided inside the threaded shell 12 , and the threaded column 13 and the threaded shell 12 are connected via threads, which can facilitate the connection between the threaded column 13 and the threaded shell 12 .

[0033] In this embodiment, the threaded column 13 is internally connected to the limiting rod 14 via a bearing, and the bottom of the limiting rod 14 is fixedly connected to the top of the mounting plate 10, which makes it easy for the threaded column 13 to drive the limiting rod 14 to move.

[0034] During use, during long-term use, if the fitting pad 6 becomes aged, the staff needs to twist the threaded column 13. The threaded column 13 will gradually leave the inside of the threaded shell 12 during the rotation. The threaded column 13 will synchronously drive the limiting rod body 14 to move during the rotation. Since the threaded column 13 and the limiting rod body 14 are connected by a bearing, the limiting rod body 14 will not rotate. The limiting rod body 14 will synchronously drive the mounting plate 10 to move during the upward movement. The mounting plate 10 will synchronously drive the fixing plate 9 and the threaded rod 8 to move upward during the movement. The threaded rod 8 will synchronously drive the embedded shell 7 and the fitting pad 6 to leave the inside of the connection valve seat 1 during the movement. Then the staff rotates the embedded shell 7, and the embedded shell 7 will gradually separate from the threaded rod 8. After that, the staff can replace or maintain the fitting pad 6 and the embedded shell 7.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
