Description

Technical Field

[0001] This utility model belongs to the field of ball valve technology, specifically a jacketed insulated ball valve. Background Technology

[0002] A jacketed insulated ball valve is a valve used to control fluid flow. It features internal and external jacket insulation and is primarily used in piping systems requiring temperature maintenance. Its design includes an inner ball cavity and an outer jacket. An insulating medium, such as hot water or steam, can be circulated through the jacket to maintain the temperature of the fluid inside the valve. Jacketed insulated ball valves are widely used in industries such as chemical, petroleum, and food processing, especially in high-temperature, low-temperature, or precise temperature control applications.

[0003] Conventional jacketed insulated ball valves have a valve stem above the ball valve core. Rotating the valve stem rotates the ball valve core, which in turn opens and closes the passage. However, in actual use, the rotation of the valve stem becomes very difficult due to fluid pressure. When the liquid pressure is high, it is difficult to rotate the valve stem directly, and it is also impossible to disconnect the valve stem from the ball valve core at the bottom. This poses a risk of misoperation when not in use. Utility Model Content

[0004] The purpose of this utility model is to provide a jacketed insulated ball valve to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a jacketed insulated ball valve, comprising a jacket, a spherical valve core movably installed inside the jacket, the spherical valve core rotating relative to the jacket, a fluid channel penetrating from front to back being opened in the middle of the spherical valve core, water inlets fixedly connected to both ends of the jacket, the device being in a conducting state when the fluid channel opened on the spherical valve core rotates to the water inlet, a valve stem fixedly installed at the top of the spherical valve core, the top of the valve stem penetrating the top of the jacket, the valve stem rotating relative to the jacket, a frame fixedly installed on one side of the jacket, an extension plate fixedly installed on the side of the frame away from the jacket, a longitudinal guide rail fixedly installed on the side of the extension plate away from the frame, a synchronization frame provided on one side of the longitudinal guide rail, and an operating component installed on the inner side of the synchronization frame;

[0006] When the synchronization frame moves down as a whole, one side of the control component is connected to the ball valve core, and the ball valve core is driven to rotate by the rotation of the control component.

[0007] When the device is in normal use, that is, when the fluid channel on the ball valve core does not correspond to the two water inlets, the device is in the closed state and the fluid cannot pass through the device. When the ball valve core rotates to the point where the fluid channel corresponds to the water inlet, the fluid can pass through the water inlet and the fluid channel to complete the process of opening and closing the fluid.

[0008] As a further technical solution of this utility model, a longitudinal locking block is fixedly installed at one end of the synchronization frame near the longitudinal guide rail. The synchronization frame is movably locked to the longitudinal guide rail through the longitudinal locking block, and the synchronization frame moves up and down relative to the longitudinal guide rail.

[0009] As a further technical solution of this utility model, the operating component includes a turntable, a first connecting shaft is installed at the bottom of the turntable, and the first connecting shaft passes through the upper and lower ends of the timing frame and is movably connected to the timing frame. A drive gear is fixedly sleeved on the outer side of the first connecting shaft, and a second connecting shaft is movably sleeved on the left side of the timing frame, and a driven gear is fixedly sleeved on the outer side of the second connecting shaft.

[0010] As a further technical solution of this utility model, the driving gear and the driven gear are meshed together, and the driven gear is located directly above the valve stem.

[0011] As a further technical solution of this utility model, the gear ratio between the driving gear and the driven gear is three to one.

[0012] When it is necessary to open the fluid passage, the movable engagement between the transmission rod and the transmission sleeve can be maintained, and the turntable can be rotated. At this time, the driving gear at the bottom will rotate accordingly, and drive the driven gear on one side to rotate. Through the cooperation between the driving gear and the driven gear, the transmission rod at the bottom will rotate rapidly, and drive the transmission sleeve, valve stem and ball valve core at the bottom to rotate relative to the jacket until the fluid passage and the water inlet are aligned, thus completing the rapid opening of the fluid passage. Conversely, the fluid passage can be quickly closed.

[0013] By utilizing the interaction between the control components and the transmission sleeve, specifically the interaction between the driving gear and the driven gear, the torque is amplified, making it easy to rotate the valve stem to quickly open and close the flow channel. The entire process does not require direct rotation of the valve stem, is less affected by fluid pressure, reduces the pressure required to rotate the valve stem, and improves the ease of use of the device.

[0014] As a further technical solution of this utility model, a transmission rod located directly above the valve stem is fixedly installed at the bottom end of the first connecting shaft, and a limit rod is fixedly installed at the bottom end of the second connecting shaft. A limit spring is movably sleeved on the outer side of the limit rod, and the upper and lower ends of the limit spring are respectively connected to the bottom end of the synchronous frame and the top end of the extension plate.

[0015] As a further technical solution of this utility model, a transmission sleeve located directly below the transmission rod is fixedly installed at the top of the valve stem. The transmission rod and the transmission sleeve are adapted to each other. When the synchronous frame moves down as a whole, the limiting spring is compressed, and the transmission rod and the transmission sleeve are engaged. When the limiting spring is in the initial state, the transmission rod is located directly above the transmission sleeve and is not engaged with the transmission sleeve.

[0016] When the valve stem needs to be operated, the timing frame can be pressed down. At this time, the timing frame will move downward under the guidance of the longitudinal locking block and the longitudinal guide rail. The limit rod and the transmission rod will move down accordingly, and the limit spring will be compressed until the transmission rod and the transmission sleeve are engaged. At this time, the valve stem can be indirectly operated through the operating component. When not in use, stop applying pressure to the timing frame, the limit spring will automatically reset, drive the transmission rod to disengage from the transmission sleeve, and automatically disconnect the connection.

[0017] By reusing the connection between the control component and the transmission sleeve, the valve stem can only be operated by pressing down the synchronization frame during operation. When not in use, the automatic reset of the synchronization frame can automatically disconnect the connection between the control component and the transmission sleeve, avoiding the problem of misoperation when the traditional device is not in use and improving the practicality of the device.

[0018] The beneficial effects of this utility model are as follows:

[0019] (1) This utility model utilizes the cooperation between the control component and the transmission sleeve, that is, the torque is amplified by the cooperation between the driving gear and the driven gear, making it easy to rotate the valve stem to realize the rapid opening and closing of the flow channel. The whole process does not require direct rotation of the valve stem, and is less affected by fluid pressure, which can reduce the pressure of rotating the valve stem and improve the ease of use of the device.

[0020] (2) By reusing the cooperation between the control component and the transmission sleeve, the device requires the synchronous frame to be pressed down to operate the valve stem when it is in use. When not in use, the automatic reset of the synchronous frame can automatically disconnect the connection between the control component and the transmission sleeve, thus avoiding the problem of misoperation when the traditional device is not in use and improving the practicality of the device.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 5 As shown in the embodiment of this utility model, a jacketed insulated ball valve includes a jacket 1. A spherical valve core 4 is movably installed inside the jacket 1. The spherical valve core 4 rotates relative to the jacket 1. A fluid channel 5 that runs through the front and back is opened in the middle of the spherical valve core 4. Both the front and back ends of the jacket 1 are fixedly connected to water inlets 2. When the fluid channel 5 opened on the spherical valve core 4 rotates to the water inlet 2, the device is in a conductive state. A valve stem 3 is fixedly installed at the top of the spherical valve core 4. The top of the valve stem 3 passes through the top of the jacket 1. The valve stem 3 rotates relative to the jacket 1. A frame 9 is fixedly installed on one side of the jacket 1. An extension plate 8 is fixedly installed on the side of the frame 9 away from the jacket 1. A longitudinal guide rail 7 is fixedly installed on the side of the extension plate 8 away from the frame 9. A synchronization frame 10 is provided on one side of the longitudinal guide rail 7. An operating component 12 is installed on the inner side of the synchronization frame 10.

[0029] When the synchronization frame 10 moves down as a whole, one side of the control component 12 is connected to the ball valve core 4, and the ball valve core 4 is driven to rotate by the rotation of the control component 12.

[0030] When the device is in normal use, that is, when the fluid channel 5 opened on the ball valve core 4 does not correspond to the two water inlets 2, the device is in the closed state and the fluid cannot be conducted through the device. When the ball valve core 4 rotates to the point where the fluid channel 5 corresponds to the water inlet 2, the fluid can be conducted through the water inlet 2 and the fluid channel 5, thus completing the process of fluid conduction and closure.

[0031] like Figure 1 and Figure 4 as well as Figure 5 As shown, a longitudinal locking block 11 is fixedly installed at one end of the synchronous frame 10 near the longitudinal guide rail 7. The synchronous frame 10 is movably locked to the longitudinal guide rail 7 through the longitudinal locking block 11. The synchronous frame 10 moves up and down relative to the longitudinal guide rail 7. The operating component 12 includes a turntable 121. A first connecting shaft is installed at the bottom end of the turntable 121. The first connecting shaft passes through the upper and lower ends of the synchronous frame 10 and is movably connected to the synchronous frame 10. A drive gear 124 is fixedly sleeved on the outer side of the first connecting shaft. A second connecting shaft is movably sleeved on the left side of the synchronous frame 10. A driven gear 125 is fixedly sleeved on the outer side of the second connecting shaft. The drive gear 124 and the driven gear 125 are meshed. The driven gear 125 is located directly above the valve stem 3. The gear ratio between the drive gear 124 and the driven gear 125 is three to one.

[0032] When it is necessary to open the fluid passage, the movable engagement between the transmission rod 126 and the transmission sleeve 6 can be maintained, and the turntable 121 can be rotated. At this time, the driving gear 124 at the bottom will rotate accordingly and drive the driven gear 125 on one side to rotate. Through the cooperation between the driving gear 124 and the driven gear 125, the transmission rod 126 at the bottom will rotate rapidly and drive the transmission sleeve 6, valve stem 3 and ball valve core 4 at the bottom to rotate relative to the jacket 1 until the fluid passage 5 and the water inlet 2 correspond to each other, thus completing the rapid opening of the fluid passage. Conversely, the fluid passage can be quickly closed.

[0033] By utilizing the cooperation between the control component 12 and the transmission sleeve 6, that is, through the cooperation between the driving gear 124 and the driven gear 125, the torque is amplified, making it easy to rotate the valve stem 3 to achieve rapid opening and closing of the flow channel. The entire process does not require direct rotation of the valve stem 3, and is less affected by fluid pressure, which can reduce the pressure of rotating the valve stem 3 and improve the ease of use of the device.

[0034] like Figure 1 and Figure 4 As shown, a transmission rod 126 located directly above the valve stem 3 is fixedly installed at the bottom end of the first connecting shaft, and a limit rod 122 is fixedly installed at the bottom end of the second connecting shaft. A limit spring 123 is movably sleeved on the outer side of the limit rod 122. The upper and lower ends of the limit spring 123 are respectively connected to the bottom end of the synchronous frame 10 and the top end of the extension plate 8. A transmission sleeve 6 located directly below the transmission rod 126 is fixedly installed at the top end of the valve stem 3. The transmission rod 126 and the transmission sleeve 6 are adapted to each other. When the synchronous frame 10 moves down as a whole, the limit spring 123 is compressed, and the transmission rod 126 and the transmission sleeve 6 are engaged. When the limit spring 123 is in the initial state, the transmission rod 126 is located directly above the transmission sleeve 6 and is not engaged with the transmission sleeve 6.

[0035] When it is necessary to operate the valve stem 3, the synchronous frame 10 can be pressed down. At this time, the synchronous frame 10 can be displaced downward under the guidance of the longitudinal locking block 11 and the longitudinal guide rail 7. At this time, the limiting rod 122 and the transmission rod 126 move down accordingly, and the limiting spring 123 is compressed until the transmission rod 126 and the transmission sleeve 6 are engaged. At this time, the valve stem 3 can be indirectly operated through the operating component 12. When not in use, stop applying pressure to the synchronous frame 10, the limiting spring 123 automatically resets, drives the transmission rod 126 to disengage from the transmission sleeve 6, and automatically disconnects the connection.

[0036] By reusing the cooperation between the control component 12 and the transmission sleeve 6, the valve stem 3 can only be operated by pressing down the synchronous frame 10 when the device is in use. When not in use, the automatic reset of the synchronous frame 10 can automatically disconnect the connection between the control component 12 and the transmission sleeve 6, avoiding the problem of misoperation when the traditional device is not in use and improving the practicality of the device.

[0037] Working principle and usage process:

[0038] When the device is in normal use, that is, when the fluid channel 5 opened on the ball valve core 4 does not correspond to the two water inlets 2, the device is in the closed state and the fluid cannot be conducted through the device. When the ball valve core 4 rotates to the point where the fluid channel 5 corresponds to the water inlet 2, the fluid can be conducted through the water inlet 2 and the fluid channel 5, thus completing the process of fluid conduction and closure.

[0039] When it is necessary to open the fluid passage, the movable engagement between the transmission rod 126 and the transmission sleeve 6 can be maintained, and the turntable 121 can be rotated. At this time, the driving gear 124 at the bottom end rotates accordingly and drives the driven gear 125 on one side to rotate. Through the cooperation between the driving gear 124 and the driven gear 125, the transmission rod 126 at the bottom end rotates rapidly and drives the transmission sleeve 6, valve stem 3 and ball valve core 4 at the bottom end to rotate relative to the jacket 1 until the fluid passage 5 and the water inlet 2 correspond to each other, thus completing the rapid opening of the fluid passage. Conversely, the fluid passage can be quickly closed.

[0040] When it is necessary to operate the valve stem 3, the synchronous frame 10 can be pressed down. At this time, the synchronous frame 10 can be displaced downward under the guidance of the longitudinal locking block 11 and the longitudinal guide rail 7. At this time, the limiting rod 122 and the transmission rod 126 move down accordingly, and the limiting spring 123 is compressed until the transmission rod 126 and the transmission sleeve 6 are engaged. At this time, the valve stem 3 can be indirectly operated through the operating component 12. When not in use, stop applying pressure to the synchronous frame 10, the limiting spring 123 automatically resets, drives the transmission rod 126 to disengage from the transmission sleeve 6, and automatically disconnects the connection.
