Description

Technical Field

[0001] This utility model relates to the field of stainless steel ball valve technology, specifically to a stainless steel ball valve with adjustable flow rate. Background Technology

[0002] Ball valves are mainly used to cut off and close the medium in pipelines and to regulate the flow rate of the medium in pipelines. They have the advantages of simple operation and convenient use. Patent number CN201822209461.6 discloses a flow-adjustable lockable ball valve. The lock prevents the locking bolt from disengaging from the locking hole and fixing hole. Without the unlocking device, outsiders cannot open the lock, and the valve stem is in a normally closed state, avoiding safety accidents caused by misoperation and saving resources. However, in the use of stainless steel ball valves, because the through hole specification of the ball valve core is fixed, and the flow rate is controlled by rotating the ball valve core to control the size of the gap between the valve body and the internal channel of the ball valve core, the operation is not stable enough, and the flow rate adjustment is not convenient enough. Therefore, we propose a flow-adjustable stainless steel ball valve. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a stainless steel ball valve with adjustable flow rate.

[0004] The technical solution adopted by this utility model to solve its technical problem is a stainless steel ball valve with adjustable flow rate, including a valve body. A valve core for controlling opening and closing is rotatably installed in the valve body, and a vertical hole is opened in the valve core. A block for adjusting flow rate is slidably installed in the vertical hole, and a blocking ring and a ring seat for sealing are screwed into the vertical hole. A vertical rod that is screwed into the ring seat is rotatably installed on the top surface of the block, and a handle that is drivenly connected to the valve core is assembled on the top surface of the valve body, and the vertical rod and the handle are inserted into each other.

[0005] The top surface of the handle is rotatably mounted with a housing, and a worm gear that engages with the vertical rod is rotatably mounted inside the housing. A worm that meshes with the worm gear is rotatably mounted inside the housing, and a rotating seat that is connected to the worm gear is mounted on the outer wall surface of the housing. An arc-shaped groove that fits with the worm gear is opened on the outer periphery of the vertical rod.

[0006] By adopting the above technical solution, when using the stainless steel ball valve, the vertical rod in the handle at the top of the valve body can be rotated, and the vertical rod and the valve stem can be inserted and slid together. Then, the vertical rod can be screwed into the ring seat on the surface of the valve core inside the valve body, so that the vertical rod rises and falls and drives the block in the vertical hole inside the valve core to rise and fall, which makes it easy to adjust the size of the through hole inside the valve core, thereby making it easy to adjust the flow rate through the ball valve, and the adjustment is simple and convenient.

[0007] When adjusting the flow rate of a stainless steel ball valve, the rotating seat on the outer side of the top of the handle can be rotated. This rotating seat drives the worm gear inside the housing to rotate, allowing the worm gear to mesh with and rotate the worm wheel inside the housing. Simultaneously, the arc-shaped groove on the outer circumference of the vertical rod engages with the protrusion on the inner circumference of the worm wheel, enabling the worm wheel to rotate the vertical rod. This allows the vertical rod to screw into the ring seat for easy raising and lowering, and the vertical rod can also slide and move along the worm wheel, facilitating the adjustment of the position of the blockage inside the valve core. The scale lines on the surface of the vertical rod allow personnel to observe the distance the blockage has moved, making it convenient to control the flow rate. Rotating the handle also rotates the valve core inside the valve body, facilitating the adjustment of the size of the passage between the valve core and the valve body. The combined use of these two features ensures more stable operation of the ball valve and facilitates flow rate adjustment.

[0008] Specifically, the valve body is equipped with a scale on its top surface, and a pointer dial that is rotatably connected to the scale is equipped on the outer periphery of the handle.

[0009] By adopting the above technical solution, the handle on the top of the valve body can rotate to drive the pointer dial to rotate, so that the pointer dial can rotate on the scale on the surface of the valve body, which makes it convenient to measure the rotation angle of the handle and facilitates the adjustment of the flow rate.

[0010] Specifically, the inner wall surface of the valve core is integrally constructed with a conical block that fits into the plug.

[0011] By adopting the above technical solution, the conical block in the valve core can fit into the groove at the bottom of the plug, which facilitates the stability when the plug and the hole in the valve core are sealed.

[0012] Specifically, a spring located on the outer periphery of the vertical rod is assembled between the plugging ring and the plugging block, and a rubber ring that fits into the vertical hole is engaged on the outer periphery of the plugging ring, and there are multiple sets of rubber rings.

[0013] By adopting the above technical solution, the spring can provide auxiliary support for the block and provide a certain buffer when the block rises. The rubber ring on the outer periphery of the blocking ring fits into the groove on the inner wall of the vertical hole, which facilitates the sealing tightness of the blocking ring when sealing the vertical hole.

[0014] Specifically, the valve core has two sets of pin holes on its top surface, and two sets of locking pins are screwed onto the top surface of the ring seat to engage with the pin holes.

[0015] By adopting the above technical solution, the ring seat and the vertical hole can be screwed together to seal them. The locking pins screwed onto the surface of the ring seat can be screwed into the pin holes on the surface of the valve core, which can improve the stability of the ring seat when sealing and reduce the rotation of the ring seat during subsequent use, so that the ring seat can be stably screwed into the vertical rod.

[0016] Specifically, the outer periphery of the vertical rod is coated with scale lines for measurement.

[0017] By adopting the above technical solution, the scale lines on the surface of the vertical rod make it easier for personnel to observe the distance the blockage moves, and facilitate personnel in adjusting the flow rate.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The technical solution of this application, through the design of valve core, vertical hole, plug, plug ring, ring seat and vertical rod, allows the vertical rod in the handle at the top of the valve body to be rotated when using the stainless steel ball valve. The vertical rod and valve stem are interlocked and slide together. Then, the vertical rod can be screwed into the ring seat on the surface of the valve core inside the valve body, so that the vertical rod rises and falls and drives the plug in the vertical hole inside the valve core to rise and fall, which facilitates the adjustment of the size of the through hole inside the valve core, thereby facilitating the adjustment of the flow rate through the ball valve. The adjustment is simple and convenient.

[0020] 2. The design of the handle, housing, worm gear, worm, rotating seat, and arc groove in this application allows for the rotation of the rotating seat on the outer side of the housing at the top of the handle when the flow rate of the stainless steel ball valve needs to be adjusted. This rotation drives the worm inside the housing to rotate, allowing the worm to mesh with the worm gear inside the housing and drive the worm gear to rotate. Simultaneously, the arc groove on the outer circumference of the vertical rod engages with the protrusion on the inner circumference of the worm gear, allowing the worm gear to drive the vertical rod to rotate. This allows the vertical rod to be screwed onto the ring seat for easy lifting and lowering. The vertical rod can also slide and move up and down along the worm gear, facilitating the adjustment of the position of the blockage inside the valve core. The scale lines on the surface of the vertical rod allow personnel to observe the distance the blockage has moved, making it convenient for personnel to control the flow rate. Furthermore, rotating the handle drives the valve core inside the valve body to rotate, facilitating the adjustment of the size of the channel between the valve core and the valve body. The combined use of these two elements allows the ball valve to operate more stably and facilitates flow rate adjustment. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Please see Figure 1-3 This utility model provides a technical solution: a stainless steel ball valve with adjustable flow rate, comprising a valve body 1, a valve core 2 for controlling opening and closing rotatably installed inside the valve body 1, a vertical hole 3 opened inside the valve core 2, a block 4 for adjusting flow rate slidably installed inside the vertical hole 3, a blocking ring 5 and a ring seat 6 for sealing screwed into the vertical hole 3, a vertical rod 7 rotatably installed on the top surface of the block 4 and screwed into the ring seat 6, and a handle 8 rotatably connected to the valve core 2 on the top surface of the valve body 1, with the vertical rod 7 inserted into the handle 8; a housing 9 rotatably installed on the top surface of the handle 8, a worm gear 10 rotatably connected to the vertical rod 7 and engaged inside the housing 9, a worm 11 rotatably installed inside the housing 9 and meshing with the worm gear 10, and a rotating seat 12 rotatably connected to the worm 11 on the outer wall surface of the housing 9; and an arc groove 13 that fits with the worm gear 10 on the outer periphery of the vertical rod 7.

[0028] When using the stainless steel ball valve, the vertical rod 7 in the handle 8 at the top of the valve body 1 can be rotated, and the vertical rod 7 and the valve stem can be inserted and slid together. Then, the vertical rod 7 can be screwed into the ring seat 6 on the surface of the valve core 2 inside the valve body 1, so that the vertical rod 7 rises and falls and drives the block 4 in the vertical hole 3 inside the valve core 2 to rise and fall, which makes it easy to adjust the size of the through hole inside the valve core 2, thereby making it easy to adjust the flow rate through the ball valve, and the adjustment is simple and convenient.

[0029] When the flow rate of the stainless steel ball valve needs to be adjusted, the rotating seat 12 on the outer side of the top housing 9 of the handle 8 can be rotated, so that the rotating seat 12 can drive the worm 11 inside the housing 9 to rotate, so that the worm 11 can mesh with the worm wheel 10 inside the housing 9 and drive the worm wheel 10 to rotate. At the same time, the arc groove 13 on the outer circumference of the vertical rod 7 and the protrusion on the inner circumference of the worm wheel 10 can fit together, so that the worm wheel 10 can drive the vertical rod 7 to rotate, so that the vertical rod 7 can be screwed together with the ring seat 6 for easy lifting and lowering. The vertical rod 7 can also slide and move up and down along the worm wheel 10, which is convenient for adjusting the position of the block 4 inside the valve core 2. At the same time, the scale line 14 on the surface of the vertical rod 7 makes it easy for personnel to observe the distance of movement of the block 4, which is convenient for personnel to control when adjusting the flow rate. When the handle 8 is rotated, it can drive the valve core 2 inside the valve body 1 to rotate, which is convenient for adjusting the size of the channel between the valve core 2 channel and the valve body 1. The two work together to make the ball valve more stable to use and convenient for flow rate adjustment.

[0030] like Figure 1 and Figure 2 As shown, a scale 19 is mounted on the top surface of the valve body 1, and a pointer 18 that is rotatably connected to the scale 19 is mounted on the outer periphery of the handle 8.

[0031] When in use, the handle 8 on the top of the valve body 1 rotates, which drives the pointer 18 to rotate, so that the pointer 18 can rotate on the scale 19 on the surface of the valve body 1, which makes it convenient to measure the rotation angle of the handle 8 and to assist in adjusting the flow rate.

[0032] like Figure 1 As shown, the inner wall surface of the valve core 2 is integrally constructed with a conical block 21 that matches the plug 4.

[0033] When in use, the conical block 21 in the valve core 2 can fit into the groove at the bottom of the plug 4, which facilitates the stability when the plug 4 and the hole in the valve core 2 are sealed.

[0034] like Figure 1 and Figure 2 As shown, a spring 20 located on the outer periphery of the vertical rod 7 is assembled between the blocking ring 5 and the blocking block 4, and a rubber ring 17 that fits into the vertical hole 3 is snapped onto the outer periphery of the blocking ring 5, and there are multiple sets of rubber rings 17.

[0035] During use, the spring 20 can provide auxiliary support for the block 4 and provide a certain buffer when the block 4 rises. The rubber ring 17 on the outer periphery of the blocking ring 5 fits into the groove on the inner wall of the vertical hole 3, which facilitates the sealing tightness of the blocking ring 5 when sealing the vertical hole 3.

[0036] like Figure 2As shown, the top surface of the valve core 2 is provided with a pin hole 15, and there are two sets of pin holes 15. The top surface of the ring seat 6 is screwed with a locking pin 16 that is screwed into the pin hole 15, and there are two sets of locking pins 16.

[0037] When in use, the ring seat 6 and the vertical hole 3 are screwed together to seal them. The locking pin 16 screwed onto the surface of the ring seat 6 can be screwed into the pin hole 15 on the surface of the valve core 2, which can improve the stability of the ring seat 6 when sealing and reduce the rotation of the ring seat 6 during subsequent use, so that the ring seat 6 can be stably screwed into the vertical rod 7.

[0038] like Figure 2 As shown, the outer periphery of the vertical rod 7 is coated with scale lines 14 for measurement.

[0039] When in use, the scale lines 14 on the surface of the vertical rod 7 make it easy for personnel to observe the distance the block 4 moves, and facilitate personnel in adjusting the flow rate.

[0040] The working principle and usage process of this utility model are as follows: In use, first install the corresponding structural components in suitable positions. When adjusting the flow rate of the stainless steel ball valve, rotate the rotating seat 12 on the outer side of the top housing 9 of the handle 8. This allows the rotating seat 12 to drive the worm gear 11 inside the housing 9 to rotate, enabling the worm gear 11 to mesh with the worm wheel 10 inside the housing 9 and drive the worm wheel 10 to rotate. Simultaneously, the arc-shaped groove 13 on the outer periphery of the vertical rod 7 engages with the protrusion on the inner periphery of the worm wheel 10, allowing the worm wheel 10 to drive the vertical rod 7 to rotate. At the same time, the vertical rod 7 and the valve stem are interlocked and slide. Subsequently, the vertical rod 7 can screw into the annular seat 6 on the surface of the valve core 2 inside the valve body 1. When the handle 8 is rotated, the vertical rod 7 rises and falls, causing the block 4 in the vertical hole 3 inside the valve core 2 to move up and down. This facilitates the adjustment of the size of the through hole inside the valve core 2, thereby facilitating the regulation of the flow rate through the ball valve. The vertical rod 7 can also slide and rise and fall along the worm gear 10, which improves the stability of the vertical rod 7 during its movement. At the same time, the scale line 14 on the surface of the vertical rod 7 makes it easy for personnel to observe the distance the block 4 moves, making it convenient for personnel to control the flow rate. When the handle 8 is rotated, it can drive the valve core 2 inside the valve body 1 to rotate, which facilitates the adjustment of the size of the channel between the valve core 2 channel and the valve body 1. The two work together to make the ball valve more stable to use and facilitate the regulation of the flow rate.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
