Description

Technical Field

[0001] This invention relates to the field of valve technology, and specifically to a combined high-temperature and high-pressure valve. Background Technology

[0002] Combined high-temperature and high-pressure valves are pipeline connectors used to switch pipelines on and off, control flow direction, and regulate and control the delivery time of working fluids. In some industrial fields, such as petrochemicals and energy, valves capable of withstanding high temperatures and pressures are frequently required to adapt to sealing conditions under various operating conditions.

[0003] In the existing technology, existing high temperature and high pressure valves are used in a high pressure environment for a long time. Therefore, at the moment the valve is opened and closed, the valve core will directly bear the impact force caused by the water hammer effect. As a result, the valve core is easily damaged by the water hammer effect, which leads to a shortened service life of the valve. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention is: a combined high-temperature and high-pressure valve, comprising:

[0005] The valve comprises a valve body, a valve seat, and a valve core; a flow-slowing mechanism for slowing the flow rate of fluid, the outer wall of which is fixedly connected to the inner wall of the valve body; a check mechanism for preventing backflow of fluid, the outer wall of which is fixedly connected to the inner wall of the valve body on the side away from the flow-slowing mechanism; the top of the valve body is fixedly connected to the bottom of the valve seat, a handwheel is rotatably connected to the top of the valve seat, a lead screw is fixedly connected to the bottom of the handwheel, a threaded sleeve is threadedly connected to the outer wall of the lead screw, and the bottom of the threaded sleeve is fixedly connected to the top of the valve core. Rotating the handwheel on the top of the valve seat causes the lead screw to rotate, and the threaded sleeve causes the valve core to slide downward along the inner wall of the valve body when the lead screw rotates, thereby closing the valve, and vice versa.

[0006] The flow-slowing mechanism includes a filter assembly, an insulator assembly fixedly connected to the inner side of the filter assembly, and a baffle ring provided on the outer side of the insulator assembly. The outer wall of the baffle ring is fixedly connected to the inner wall of the valve body. A connecting rod is fixedly connected to the side of the insulator assembly away from the filter assembly, and a baffle plate is fixedly connected to the side of the connecting rod away from the insulator assembly. During fluid flow, the fluid impacts the baffle plate, causing the surface of the baffle plate to separate from the surface of the baffle ring. At this time, the fluid can flow through the gap between the baffle plate and the baffle ring, thereby disrupting the flow direction of the fluid and slowing down the flow rate.

[0007] Preferably, the outer wall of the lead screw is rotatably connected to the inner wall of the valve seat, the inner wall of the valve seat is slidably connected to the outer wall of the threaded sleeve, the outer wall of the valve core is slidably connected to the inner wall of the valve body, an inlet pipe is fixedly connected to the bottom of the valve body, a drain pipe is fixedly connected to the bottom of the valve body, the outer side of the filter assembly is fixedly connected to the inner wall of the valve body, and the outer wall of the baffle plate is in contact with the outer wall of the baffle ring. Clean water is injected into the valve body through the inlet pipe, and the water flows in the opposite direction in the valve body. When the water flows in the opposite direction through the filter assembly, the dirt attached to the filter assembly mixes with the clean water to form sewage, which can then be discharged through the drain pipe.

[0008] Preferably, the filter assembly includes an outer cylinder, an inner cylinder is disposed inside the outer cylinder, a baffle block is fixedly connected to the outer wall of the inner cylinder, a filter plate is fixedly connected to the side of the inner cylinder away from the baffle block, a rotating ring is rotatably connected to the outer wall of the inner cylinder, a baffle plate is fixedly connected to the outer wall of the rotating ring, a circular ring is fixedly connected to the outer wall of the baffle plate, and a cross scraper is fixedly connected to the inner wall of the circular ring. Fluid can push the baffle plate to drive the rotating ring to rotate.

[0009] Preferably, the outer wall of the outer cylinder is fixedly connected to the inner wall of the valve body, the inner wall of the valve body is fixedly connected to the outer wall of the baffle block, the baffle block is arranged in a ring along the central axis of the outer cylinder, the outer wall of the ring is rotatably connected to the inner wall of the outer cylinder, the outer wall of the cross scraper is slidably connected to the outer wall of the filter plate, the ring can rotate with the baffle block, and in the process of rotation, it drives the cross scraper to slide along the surface of the filter plate, thereby cleaning the filter plate.

[0010] Preferably, the turbulence-disrupting component includes an umbrella-shaped block, with a variable-diameter helical spring fixedly connected to the outer wall of the umbrella-shaped block. A fixing ring is fixedly connected to the end of the variable-diameter helical spring away from the umbrella-shaped block. The outer wall of the umbrella-shaped block is slidably connected to the inner wall of the inner cylinder, and the inner wall of the inner cylinder is fixedly connected to the outer wall of the fixing ring. A through hole is provided in the wall of the umbrella-shaped block. During the process of the fluid pushing the umbrella-shaped block, part of the kinetic energy of the fluid is converted into the elastic potential energy of the variable-diameter helical spring, thereby achieving the purpose of consuming the kinetic energy of the fluid and further slowing down the flow rate of the fluid.

[0011] Preferably, the check valve mechanism includes a fixed sleeve, the inner wall of which is connected to a tension spring, and the end of the tension spring away from the fixed sleeve is fixedly connected to a sliding ring. The outer wall of the sliding ring is fixedly connected to a baffle. During the flow of fluid, the baffle is pushed open, at which time the surface of the baffle separates from the surface of the fixed sleeve, the sliding ring slides out from the fixed sleeve, and the tension spring is stretched by force. Then the fluid can flow out of the valve body through the guide hole.

[0012] Preferably, the sliding ring has a flow guide hole in its wall, the outer wall of the sliding ring is slidably connected to the inner wall of the fixed sleeve, the outer wall of the fixed sleeve is fixedly connected to the inner wall of the valve body, one side of the baffle is in contact with the outer wall of the fixed sleeve, and the other side of the baffle is in contact with the inner wall of the valve body. When the valve is closed and the fluid flows back, under the impact force of the water flow and the tension of the tension spring, the surface of the baffle contacts the surface of the fixed sleeve, thus restricting the flow of fluid.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. The present invention sets up a flow slowing mechanism. During the fluid flow process, the fluid impacts the baffle plate, causing the surface of the baffle plate to separate from the surface of the baffle ring. At this time, the fluid can flow through the gap between the baffle plate and the baffle ring, thereby disrupting the flow direction of the fluid and slowing down the flow rate of the fluid. Subsequently, the filter assembly can filter the fluid and filter out the impurities mixed in the fluid.

[0015] 2. By setting up a flow-disrupting component, when the flow-disrupting component deforms, the variable-diameter helical spring is compressed by force, and the umbrella-shaped block takes the shape of an open umbrella, which can increase its contact area with the fluid. During the process of the fluid pushing the umbrella-shaped block, part of the fluid's kinetic energy is converted into the elastic potential energy of the variable-diameter helical spring, thereby achieving the purpose of consuming the fluid's kinetic energy. This can further slow down the fluid's flow rate and protect the valve core, preventing the valve core from being damaged by water hammer effect at the moment the valve is opened.

[0016] 3. By setting up a filter assembly, the fluid passes through the surface of the filter plate. The filter plate can filter impurities mixed in the fluid, preventing large particles of impurities from flowing with the fluid and damaging the valve core. At the same time, a small part of the fluid forms a flow barrier between the baffles and passes through the gaps, pushing the baffle to drive the rotating ring to rotate. At this time, the ring drives the cross scraper to slide along the surface of the filter plate, thereby cleaning the filter plate and preventing the filter plate surface from clogging.

[0017] 4. By setting a check mechanism, when the valve is closed and the fluid flows back, the surface of the baffle contacts the surface of the fixed sleeve under the impact force of the water flow and the tension of the tension spring, thus restricting the flow of fluid and protecting the valve core from damage caused by the impact force of the water flow.

[0018] 5. By setting up an inlet pipe and a drain pipe, when it is necessary to clean the dirt inside the valve body, the valve is first opened, then the drain pipe is opened, and then clean water is injected into the valve body through the inlet pipe. At this time, the water flows in the opposite direction in the valve body. When the water flows in the opposite direction through the filter component, the dirt attached to the filter component and the clean water are mixed to form sewage, which can then be discharged through the drain pipe.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0027] Example: Please refer to Figure 1 - Figure 6This invention provides a technical solution: a combined high-temperature and high-pressure valve, comprising: a valve body 1, a valve seat 2, and a valve core 6; a flow-slowing mechanism 7, used to slow down the flow rate of fluid, the outer wall of the flow-slowing mechanism 7 being fixedly connected to the inner wall of the valve body 1; a check mechanism 8, used to prevent backflow of fluid, the outer wall of the check mechanism 8 being fixedly connected to the inner wall of the valve body 1 on the side away from the flow-slowing mechanism 7; the top of the valve body 1 being fixedly connected to the bottom of the valve seat 2, a handwheel 3 being rotatably connected to the top of the valve seat 2, a lead screw 4 being fixedly connected to the bottom of the handwheel 3, and a threaded sleeve 5 being threadedly connected to the outer wall of the lead screw 4. The bottom of the threaded sleeve 5 is fixedly connected to the top of the valve core 6; the outer wall of the screw 4 is rotatably connected to the inner wall of the valve seat 2, the inner wall of the valve seat 2 is slidably connected to the outer wall of the threaded sleeve 5, the outer wall of the valve core 6 is slidably connected to the inner wall of the valve body 1, the bottom of the valve body 1 is fixedly connected to the inlet pipe 9, the bottom of the valve body 1 is fixedly connected to the drain pipe 10, the flow-slowing mechanism 7 includes a filter assembly 71, the inner side of the filter assembly 71 is fixedly connected to a flow-turbulence assembly 72, the outer side of the flow-turbulence assembly 72 is provided with a flow-blocking ring 75, the outer wall of the flow-blocking ring 75 is fixedly connected to the inner wall of the valve body 1, and the flow-turbulence assembly 72 is away from the filter assembly 71. A connecting rod 73 is fixedly connected to one side of the filter assembly 71. A baffle 74 is fixedly connected to the side of the connecting rod 73 away from the flow-damping assembly 72. The outer side of the filter assembly 71 is fixedly connected to the inner wall of the valve body 1. The outer wall of the baffle 74 contacts the outer wall of the baffle ring 75. In use, the handwheel 3 on the top of the valve seat 2 is turned, causing the screw 4 to rotate. When the screw 4 rotates, the threaded sleeve 5 drives the valve core 6 to slide downward along the inner wall of the valve body 1, thereby closing the valve. The reverse is also true. When the valve is opened, the fluid enters from the side where the flow-slowing mechanism 7 is installed. After passing through the flow-slowing mechanism 7, the flow rate is slowed down. The fluid flows out from the side where the check mechanism 8 is installed. The check mechanism 8 can prevent the fluid from flowing back and impacting the valve core 6 when the valve is closed. During the fluid flow, the fluid impacts the baffle plate 74, causing the surface of the baffle plate 74 to separate from the surface of the baffle ring 75. At this time, the fluid can flow through the gap between the baffle plate 74 and the baffle ring 75, thereby disrupting the flow direction of the fluid and slowing down the flow rate. At the same time, the baffle plate 74 pushes the turbulence component 72 to deform through the connecting rod 73, which can further slow down the flow rate of the water. Then the filter component 71 can filter the fluid and filter out the impurities mixed in the fluid.

[0028] When it is necessary to clean the dirt inside the valve body 1, first open the valve, then open the drain pipe 10, and then inject clean water into the valve body 1 through the water inlet pipe 9. At this time, the water flows in the reverse direction in the valve body 1. When the water flows in the reverse direction through the filter component 71, the dirt attached to the filter component 71 mixes with the clean water to form sewage, and then the sewage can be discharged through the drain pipe 10.

[0029] The filter assembly 71 includes an outer cylinder 711, an inner cylinder 712 disposed inside the outer cylinder 711, a baffle block 713 fixedly connected to the outer wall of the inner cylinder 712, a filter plate 716 fixedly connected to the side of the inner cylinder 712 away from the baffle block 713, a rotating ring 714 rotatably connected to the outer wall of the inner cylinder 712, a baffle plate 715 fixedly connected to the outer wall of the rotating ring 714, a circular ring 717 fixedly connected to the outer wall of the baffle plate 715, a cross scraper 718 fixedly connected to the inner wall of the circular ring 717, the outer wall of the outer cylinder 711 fixedly connected to the inner wall of the valve body 1, the inner wall of the valve body 1 fixedly connected to the outer wall of the baffle block 713, the baffle block 713 being arranged in a ring array along the central axis of the outer cylinder 711, and the outer wall of the circular ring 717 being rotatably connected to the inner wall of the outer cylinder 711. The outer wall of the cross scraper 718 is slidably connected to the outer wall of the filter plate 716. After the fluid passes through the turbulence assembly 72, it passes through the surface of the filter plate 716. The filter plate 716 can filter impurities mixed in the fluid and prevent large particles of impurities from flowing with the fluid and damaging the valve core 6. At the same time, a small part of the fluid forms a gap between the turbulence blocks 713 and flows between the outer cylinder 711 and the inner cylinder 712. During this process, the fluid pushes the turbulence plate 715 to drive the rotating ring 714 to rotate. At this time, the ring 717 rotates with the turbulence plate 715 and drives the cross scraper 718 to slide along the surface of the filter plate 716 during the rotation. This can clean the filter plate 716 and prevent the surface of the filter plate 716 from becoming clogged.

[0030] The aerodynamic component 72 includes an umbrella-shaped block 721. A variable-diameter helical spring 722 is fixedly connected to the outer wall of the umbrella-shaped block 721. A fixing ring 723 is fixedly connected to the end of the variable-diameter helical spring 722 away from the umbrella-shaped block 721. The outer wall of the umbrella-shaped block 721 is slidably connected to the inner wall of the inner cylinder 712. The inner wall of the inner cylinder 712 is fixedly connected to the outer wall of the fixing ring 723. A through hole 724 is provided in the wall of the umbrella-shaped block 721. When the aerodynamic component 72 deforms, the baffle plate 74 pushes the umbrella-shaped block 721 toward the fixing ring through the connecting rod 73. When 723 approaches, the variable diameter helical spring 722 is compressed, and the fluid passes through the through hole 724 on the surface of the umbrella block 721. The umbrella block 721 is shaped like an open umbrella, which can increase its contact area with the fluid. During the process of the fluid pushing the umbrella block 721, part of the fluid's kinetic energy is converted into the elastic potential energy of the variable diameter helical spring 722, thereby achieving the purpose of consuming the fluid's kinetic energy. This can further slow down the fluid's flow rate and protect the valve core 6, preventing the valve core 6 from being damaged by water hammer effect at the moment the valve is opened.

[0031] The check mechanism 8 includes a fixed sleeve 81, a tension spring 82 connected to the inner wall of the fixed sleeve 81, a sliding ring 83 fixedly connected to the end of the tension spring 82 away from the fixed sleeve 81, a baffle 84 fixedly connected to the outer wall of the sliding ring 83, a guide hole 85 formed in the wall of the sliding ring 83, the outer wall of the sliding ring 83 slidably connected to the inner wall of the fixed sleeve 81, the outer wall of the fixed sleeve 81 fixedly connected to the inner wall of the valve body 1, one side of the baffle 84 contacts the outer wall of the fixed sleeve 81, and the other side of the baffle 84 contacts the inner wall of the valve body 1. During the flow of fluid, the baffle 84 is pushed open, at which point the surface of the baffle 84 separates from the surface of the fixed sleeve 81, the sliding ring 83 slides out from the fixed sleeve 81, and the tension spring 82 is stretched. Then the fluid can flow out from the valve body 1 through the guide hole 85. When the valve is closed and the fluid flows back, under the impact force of the water flow and the tension of the tension spring 82, the surface of the baffle 84 contacts the surface of the fixed sleeve 81, restricting the flow of fluid and thus protecting the valve core 6 from damage caused by the impact force of the water flow.

[0032] Working principle:

[0033] When in use, turn the handwheel 3 on the top of the valve seat 2, so that the handwheel 3 drives the screw 4 to rotate. When the screw 4 rotates, the threaded sleeve 5 drives the valve core 6 to slide down along the inner wall of the valve body 1, thereby closing the valve. The reverse is also true.

[0034] When the valve is opened, the fluid enters from the side where the flow slowing mechanism 7 is installed. After the flow slowing mechanism 7 reduces the flow rate, the fluid flows out from the side where the check mechanism 8 is installed. The check mechanism 8 can prevent the fluid from flowing back and impacting the valve core 6 when the valve is closed.

[0035] During the fluid flow, the fluid impacts the baffle plate 74, causing the surface of the baffle plate 74 to separate from the surface of the baffle ring 75. At this time, the fluid can flow through the gap between the baffle plate 74 and the baffle ring 75, thereby disrupting the flow direction of the fluid and slowing down the flow rate. At the same time, the baffle plate 74 pushes the turbulence component 72 to deform through the connecting rod 73, which can further slow down the flow rate of the water. Then the filter component 71 can filter the fluid and remove impurities mixed in the fluid.

[0036] When the turbulence component 72 deforms, the baffle plate 74 pushes the umbrella block 721 closer to the fixed ring 723 through the connecting rod 73. At this time, the variable diameter helical spring 722 is compressed by force, and the fluid passes through the through hole 724 on the surface of the umbrella block 721. The umbrella block 721 is shaped like an open umbrella, which can increase its contact area with the fluid. During the process of the fluid pushing the umbrella block 721, part of the fluid's kinetic energy is converted into the elastic potential energy of the variable diameter helical spring 722, thereby achieving the purpose of consuming the fluid's kinetic energy. This can further slow down the fluid's flow rate and protect the valve core 6, preventing the valve core 6 from being damaged by water hammer effect at the moment the valve is opened.

[0037] After the fluid passes through the turbulence assembly 72, it passes through the surface of the filter plate 716. The filter plate 716 can filter impurities mixed in the fluid and prevent large particles of impurities from flowing with the fluid and damaging the valve core 6. At the same time, a small part of the fluid forms a gap between the turbulence blocks 713 and flows through the gap between the outer cylinder 711 and the inner cylinder 712. During this process, the fluid pushes the turbulence plate 715 to drive the rotating ring 714 to rotate. At this time, the ring 717 rotates with the turbulence plate 715 and drives the cross scraper 718 to slide along the surface of the filter plate 716 during the rotation. This can clean the filter plate 716 and prevent the surface of the filter plate 716 from clogging.

[0038] The fluid then continues to flow and pushes the baffle 84 open during the flow. At this time, the surface of the baffle 84 separates from the surface of the fixed sleeve 81, the sliding ring 83 slides out from the fixed sleeve 81, and the tension spring 82 is stretched by force. Then the fluid can flow out from the valve body 1 through the guide hole 85.

[0039] When the valve is closed and the fluid flows back, under the impact of the water flow and the tension of the tension spring 82, the surface of the baffle 84 contacts the surface of the fixed sleeve 81, restricting the flow of fluid and thus protecting the valve core 6 from damage caused by the impact of the water flow.

[0040] When it is necessary to clean the dirt inside the valve body 1, first open the valve, then open the drain pipe 10, and then inject clean water into the valve body 1 through the water inlet pipe 9. At this time, the water flows in the reverse direction in the valve body 1. When the water flows in the reverse direction through the filter component 71, the dirt attached to the filter component 71 mixes with the clean water to form sewage, and then the sewage can be discharged through the drain pipe 10.
