Description

Technical Field

[0001] This utility model belongs to the technical field of chemical equipment, and specifically relates to a jacketed insulated glass valve. Background Technology

[0002] In industries such as chemical, pharmaceutical, and food processing, it is often necessary to transport various liquid media, including some liquids that are prone to crystallization. Currently, these easily crystallizing liquids tend to accumulate inside valve bodies when passing through them, which can not only cause valve blockage and affect normal operation, but also damage the valve core, especially the sealing surface of PTFE valve cores, thereby shortening the valve's service life.

[0003] Existing technologies address problems arising when easily crystallizing liquids pass through valves, such as patent applications CN204704393U – a material valve with a bellows seal and a heat-insulating jacket structure, and CN210716094U – a pneumatic jacketed insulated three-way regulating valve. These valves utilize a jacketed insulation structure to heat the material inside the valve, effectively preventing crystallization and solidification. This solves the current problems of easily crystallizing liquids clogging valves and damaging the valve core. However, existing jacketed insulated valves only ensure the flow of easily crystallizing materials within the valve. During the heating process with the hot medium, some gas is generated inside the valve body. If this gas is not discharged in time, it will not only affect the quality of the material but also threaten the safety of valve operation. Therefore, a new technical solution is needed to address these technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a jacketed insulated glass valve to solve the problems mentioned in the background art, such as the difficulty in timely discharge of gas generated during the heating process of the hot medium in current jacketed insulated valves, which affects the quality of materials and even threatens the safety of valve use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a jacketed insulated glass valve, comprising a valve body and a jacket sleeved outside the valve body. A feed pipe is inclined upwards on one side of the valve body. A vent pipe is horizontally connected to the feed pipe at its intersection with the valve body. The vent pipe and feed pipe are perpendicular to the longitudinal section of the valve body, and their outlet ends sequentially penetrate the valve body wall and the jacket wall, extending to the outside of the jacket and being on the same vertical plane as the inlet end of a hot inlet pipe located at the lower end of one side of the jacket. A hot outlet pipe is connected to the upper end of the other side of the jacket. The hot outlet pipe and the vent pipe are arranged on the same horizontal plane. The outlet end of the hot outlet pipe is opposite to the outlet end of the vent pipe. The inlet end of the vent pipe is vertically downwards relative to the longitudinal section of the valve body and communicates with the interior of the valve body. A discharge pipe is bent downwards on the lower part of the other side of the valve body. The discharge pipe and feed pipe are opposite to the longitudinal section of the valve body.

[0006] Furthermore, one end of the feed pipe is fixedly connected to the top of the valve body to form an integral structure, and the other end of the feed pipe penetrates the jacket wall and extends to the outside of the jacket to be connected to a material conveying device; one end of the discharge pipe is fixedly connected to the lower side of the valve body to form an integral structure, and the other end of the discharge pipe penetrates the jacket wall and extends to the outside of the jacket to be connected to a material collecting device.

[0007] Furthermore, a valve cover is fixedly connected to the flange at the lower end of the valve body via a flange. A nut is provided inside the valve cover, and a lifting screw is threadedly connected to the nut. The upper end of the lifting screw extends upward from the nut inside the valve cover to the interior of the valve body and is fixedly connected to the PTFE bellows valve core located inside the valve body. The lower end of the lifting screw extends downward from the nut inside the valve cover to the bottom end of the valve cover and is fixedly connected to the operating wheel rotating at the bottom of the valve cover. The lifting screw moves up and down on the valve cover via the operating wheel and simultaneously drives the PTFE bellows valve core to move up and down inside the valve body.

[0008] Furthermore, the operating wheel can be configured for manual operation, pneumatic operation, or electric operation.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This utility model cleverly designs a horizontally connected vent pipe at the intersection of the feed pipe and the valve body. This not only ensures that the gas generated inside the valve body during the heating process of the hot medium can be discharged smoothly and timely from inside the valve body to outside the jacket, effectively avoiding the impact of gas accumulation inside the valve body on material quality and valve safety, but also maintains the pressure balance inside the valve body, further improving the stability and reliability of the valve. At the same time, the vent pipe can be used to introduce gas or liquid into the valve body for mixing and reaction, effectively improving the functionality and practicality of the glass valve. By designing the outlet end of the vent pipe and the inlet end of the hot inlet pipe of the jacket to be on the same vertical plane, it not only facilitates the discharge of gas and the introduction of the hot medium, further improving heating efficiency, but also allows the gas discharged from the valve body to be recycled as a hot medium, realizing the rational use of energy. By continuing to use the jacket insulation structure, uniform heating and insulation of the material inside the valve body are achieved, effectively preventing the crystallization and solidification of easily crystallizing liquids. This not only solves the problem of easy clogging and damage to the valve core in conventional valves, but also further extends the service life of the valve and improves working efficiency.

[0011] 2. This utility model adopts an integrated structure for the valve body, inlet pipe, and outlet pipe, which not only enhances the overall structural strength of the valve body but also improves its sealing performance, reduces the risk of material leakage, and ensures the continuity and safety of the production process. By tilting the inlet pipe upward, the material flows smoothly into the valve body under gravity, reducing the risk of material accumulation and blockage during the conveying process. This not only improves the efficiency of material conveying but also helps to keep the inside of the valve body clean and unobstructed. By bending the outlet pipe downward, the material is smoothly discharged into the material collection device, which helps to reduce material loss and waste during the discharge process and improves the overall efficiency of the production process. With both the inlet and outlet pipes penetrating the jacket wall and extending to the outside of the jacket, the heat medium inside the jacket can also heat or insulate the material in the inlet and outlet pipes, making heat transfer more efficient and uniform, thereby enhancing the insulation effect of the jacket.

[0012] 3. This utility model adopts an inlet vertically downward vent pipe, which ensures that gas can flow smoothly from the inside of the valve body to the vent pipe, effectively avoiding the pressure rise and potential safety hazards caused by gas accumulation. The vent pipe and feed pipe are vertically distributed relative to the longitudinal section of the valve body, which helps to reduce the flow resistance of the hot medium, allowing the hot medium to circulate more smoothly inside the jacket, further improving the heat exchange efficiency. The reasonable layout of the vent pipe, the hot outlet pipe and the hot inlet pipe not only helps to achieve efficient circulation of the hot medium, allowing the hot medium to be evenly distributed or flow inside the jacket, but also helps to reduce the risk of deformation and cracking of the valve body under thermal stress, further enhancing the structural stability and service life of the glass valve.

[0013] 4. This utility model, through the connection between the lifting screw and the operating wheel, allows operators to more conveniently and quickly adjust the height of the PTFE bellows valve core by rotating the operating wheel, thereby opening and closing the glass valve. This not only improves the operational flexibility of the glass valve but also enables more precise control of material flow and pressure. Utilizing the corrosion resistance and wear resistance of PTFE bellows, the stability and sealing of the valve core during lifting are ensured, reducing the risk of material leakage. The threaded connection between the lifting screw and the nut inside the valve cover simplifies the lifting and replacement of the PTFE bellows valve core, eliminating the need for large-scale disassembly of the entire glass valve, thus reducing maintenance costs and downtime. By setting the operating wheel to manual, pneumatic, or electric operation, the glass valve meets the needs of different application scenarios. Attached Figure Description

[0020] The following embodiments are used to further illustrate the content of this utility model, and do not limit the application of this utility model.

[0021] Please see Figures 1-5 This utility model provides a jacketed insulated glass valve, including a valve body 1 for material discharge and a jacket 2 sleeved outside the valve body 1 for heating or insulating the material inside the valve body 1. A feed pipe 3 for conveying material into the valve body 1 is inclined upwards on one side of the valve body 1. One end of the feed pipe 3 is fixedly connected to the top of the valve body 1 to form an integral structure. The other end of the feed pipe 3 penetrates the jacket wall and extends to the outside of the jacket 2, where a material conveying device is connected for material conveying (the functions and structures of conventional equipment such as material conveying devices are known in the art, and the connection settings are also known). (This is common knowledge, so it will not be explained in detail here, and it is not shown in the attached drawings.) The lower part of the other side of the valve body 1 is bent downward and connected to the discharge pipe 4 for discharging materials. The discharge pipe 4 and the feed pipe 3 are arranged opposite to each other with respect to the longitudinal section of the valve body 1. One end of the discharge pipe 4 is fixedly connected to the lower side of the valve body 1 to form an integral structure. The other end of the discharge pipe 4 penetrates the jacket wall and extends to the outside of the jacket 2 to connect to a material collection device (the function and structure of conventional equipment such as the material collection device are known in the art, and the connection settings are also common knowledge, so they will not be explained in detail here, and they are not shown in the attached drawings.)

[0022] The feed pipe 3 is horizontally connected to the vent pipe 5 at the position where it intersects with the valve body 1. The vent pipe 5 and the feed pipe 3 are perpendicular to the longitudinal section of the valve body. The inlet end of the vent pipe 5 is vertically downward relative to the longitudinal section of the valve body 1 and is connected to the interior of the valve body 1. The outlet end of the vent pipe 5 penetrates the valve body wall and the jacket wall in sequence and extends to the outside of the jacket 2. It is on the same vertical plane as the inlet end of the hot inlet pipe 6 located at the lower end of one side of the jacket 2 and used for the entry of the hot medium. The upper end of the other side of the jacket 2 is connected to the hot outlet pipe 7 used for the discharge of the hot medium. The hot outlet pipe 7 and the vent pipe 5 are set on the same horizontal plane and its outlet end is opposite to the outlet end of the vent pipe 5.

[0023] Please see Figures 1-2 and Figures 4-5 The valve cover 10 is fixedly connected to the flange port 8 at the lower end of the valve body 1 via the flange 9. The valve cover 10 has a nut inside (the function and structure of conventional equipment such as nuts are well known in the art, and the connection settings are also common knowledge, so they will not be explained here and are not shown in the attached drawings) and a lifting screw 11 for driving the PTFE bellows valve core 12 to rise and fall is connected to the nut via the nut thread.

[0024] The upper end of the lifting screw 11 extends upward from the nut inside the valve cover 10 to the inside of the valve body 1 and is fixedly connected to the PTFE bellows valve core 12 located inside the valve body 1. The lower end of the lifting screw 11 extends downward from the nut inside the valve cover 10 to the bottom of the valve cover 10 and is fixedly connected to the operating wheel 13 rotating at the bottom of the valve cover 10. The lifting screw 11 is raised and lowered on the valve cover 10 by rotating the operating wheel 13, and at the same time, it drives the PTFE bellows valve core 12 to rise and fall inside the valve body 1, thereby realizing the opening and closing of the valve.

[0025] When the valve is small or used infrequently, the operating wheel 13 can be operated manually; when the valve is large, used infrequently, or requires remote control, the operating wheel 13 can be operated pneumatically or electrically (the basic structure such as the pneumatic and electric functions on the existing operating wheel is not described in detail here, but should not limit its functionality).

[0026] The working principle and usage process of this utility model are as follows: Figures 1-5As illustrated, after the jacketed insulated glass valve is assembled, the operator installs the entire jacketed insulated glass valve onto the liquid material production equipment (the functions and structures of conventional equipment such as liquid material production equipment are well known in the field, and the connection settings are also common knowledge, so they will not be explained in detail here, nor are they shown in the attached drawings). This enables uniform heating and insulation of the material inside the valve body, effectively preventing the crystallization and solidification of easily crystallizing liquids. It not only solves the problem of conventional valves being prone to clogging and damaging the valve core, but also further extends the service life of the valve and improves working efficiency. At the same time, the vent pipe 5 can be used to promptly and smoothly discharge the gas generated inside the valve body during the heating process of the hot medium, effectively solving the problem of the impact of gas accumulation inside the valve body on material quality and valve safety.

[0027] When easily crystallizing liquid materials need to be discharged or transported, the operator first connects the material conveying device of the liquid material production equipment to the feed pipe 3, so that the liquid material produced by the liquid material production equipment enters the feed pipe 3. Since the sealing surface of the PTFE bellows valve core 12 is initially at the inner top of the valve body 1, both the feed pipe 3 and the discharge pipe 4 are sealed by the PTFE bellows valve core 12. Then, the material collection device is connected to the discharge pipe 4. Since the discharge pipe 4 is in a sealed state, the liquid material cannot be discharged from the discharge pipe 4. Then, the operating wheel 13 is rotated to move the lifting screw 11 downward. The PTFE bellows valve core 12 will move downward synchronously with the lifting screw 11 until the feed pipe 3 and the discharge pipe 4 are in a smooth state. At this time, the liquid material discharged into the feed pipe 3 will enter the valve body 1 through the feed pipe 3, and then enter the discharge pipe 4 through the valve body 1, and then be discharged into the material collection device through the discharge pipe 4.

[0028] As the liquid material enters the valve body 1, a hot medium (which can be hot water or steam) is discharged into the jacket 2 through the inlet end of the hot inlet pipe 6. This heats and keeps the liquid material inside the valve body 1 warm under the heating effect of the hot medium in the jacket 2, ensuring that the liquid material remains in a flowing state within the valve body 1. During the heating and warming process, some gas is generated, which accumulates inside the valve body 1 and affects the quality of the liquid material and the safety of valve operation. Therefore, this gas enters the vent pipe 5 through the inlet end and is discharged through the outlet end of the vent pipe 5, maintaining a constant pressure balance inside the valve body 1 and further improving the stability and reliability of the valve.

[0029] When the easily crystallizing liquid material is discharged or the conveying is finished, the operator will rotate the operating wheel 13 to move the lifting screw 11 upward. The PTFE bellows valve core 12 moves upward synchronously with the lifting screw 11 until the feed pipe 3 and the discharge pipe 4 are sealed again. At the same time, the conveying of the hot medium into the jacket 2 is stopped, and the hot medium in the jacket 2 will also be discharged through the hot outlet pipe 7, that is, the heating and heat preservation of the inside of the valve body 1 is stopped.

[0030] When the materials in the valve body 1 need to undergo a mixing reaction, the operator only needs to let the gas or liquid involved in the mixing reaction enter the vent pipe 5 through the outlet end of the vent pipe 5 and then discharge it into the valve body 1 through the inlet end of the vent pipe 5, so that the gas or liquid entering can mix and react with the materials in the valve body 1.
