Description

Technical Field

[0001] The present invention relates to the technical field of ball valves, and particularly to a gate-adjusting ball valve. Background Art

[0002] A gate ball valve refers to a ball valve in which a gate hole communicating with a valve hole is opened on a valve ball, and a gate plate is installed in the gate hole, so that the valve ball controls opening and closing, and the gate plate controls the flow rate. Due to the advantages of simple structure and good sealing performance of the gate ball valve, it is widely used in water supply and drainage systems such as domestic water, heating systems, and mines.

[0003] When the existing gate ball valve is used to deal with the problem of secondary network balance adjustment in the heating system, due to factors such as the service life of each pipe network, the scaling and corrosion conditions inside the pipeline, etc., the friction coefficient used in the calculation of the head loss can only be conservatively selected. As a result, after the orifice valve transformation is implemented in the entire pipe network, nearly 30% of the orifice diameters need to be adjusted. At present, the existing gate ball valve is difficult to have the precise adjustment performance that meets the requirements of secondary network balance adjustment. Moreover, since the opening and closing of the gate ball valve is achieved by the up and down movement of the gate plate to cut off the fluid, usually when the gate valve is closed, the gate plate bears a large fluid pressure on the fluid inlet side and is easily damaged. Therefore, a gate-adjusting ball valve is proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a gate-adjusting ball valve to solve the problems that the existing gate ball valve is difficult to have the precise adjustment performance that meets the requirements of secondary network balance adjustment, and since the opening and closing of the gate ball valve is achieved by the up and down movement of the gate plate to cut off the fluid, usually when the gate valve is closed, the gate plate bears a large fluid pressure on the fluid inlet side and is easily damaged.

A same adjusting ball valve body is fixedly installed between the water inlet shunt pipe and the water outlet shunt pipe at the same location. A shunt tee is fixedly installed between the water outlet shunt pipe and the adjusting ball valve body at the same location. One end of the shunt tee extends to the outside of the adjusting housing and is screwed with a sealing screw cap.

[0006] Furthermore, valve pipe sleeves are fixedly installed on the regulating ball valve body. Switch valve pipes are rotatably installed inside the valve pipe sleeves.

[0007] Furthermore, the adjusting ball core includes a front baffle. Two symmetrically arranged rear baffles are fixedly installed on one side of the front baffle. The adjusting gate plate is slidably installed between the front baffle and the rear baffle.

[0008] Furthermore, guiding threaded grooves are formed inside the bottom ends of the switch valve pipes. Adjusting screw pipes are screwed inside the bottom ends of the switch valve pipes. An adjusting flower-shaped sliding rod is slidably installed inside the adjusting screw pipe. The top end of the adjusting flower-shaped sliding rod is fixedly installed with an adjusting outer sliding rod. The bottom end of the adjusting screw pipe extends into the regulating ball valve and is rotatably installed with an adjusting gate plate. The adjusting gate plate is slidably installed inside the adjusting ball core.

[0009] Furthermore, the gate plate adjusting mechanism includes an adjusting motor fixedly installed on one side of the water inlet manifold pipe. The output shaft of the adjusting motor is drivingly installed with a horizontally arranged adjusting shaft. A flower-shaped shaft is fixedly installed at one end of the adjusting shaft. A suspension disc is fixedly installed on one side of the water outlet manifold pipe. A suspension shaft sleeve is fixedly installed on one side of the suspension disc.

An electric slider is drivingly installed on the linear guide rail. An adjusting rack is fixedly installed on the electric slider. One end of the adjusting outer sliding rod located outside the switch valve pipe is slidably sleeved with an adjusting gear adapted to the adjusting rack.

[0010] Furthermore, the side walls of the adjusting gears are all arc-shaped.

[0011] Furthermore, a switch gear ring is slidably sleeved on the flower-shaped shaft. A plurality of uniformly distributed reset spring rods are fixedly installed on one side of the suspension disc. The telescopic ends of the plurality of reset spring rods are fixedly installed with the same bearing ring. The switch gear ring is rotatably connected to the bearing ring. A plurality of uniformly distributed suspension frames are fixedly installed inside the adjusting housing. Horizontally arranged switch rods are rotatably installed on the suspension frames. The plurality of switch rods are respectively located on one side of the plurality of regulating ball valve bodies. One end of the switch rod and one end of the switch valve pipe located outside the valve pipe sleeve are fixedly sleeved with switch bevel gears. The two switch bevel gears at the same position are meshed with each other. The other end of the switch rod is fixedly sleeved with a driven gear.

By setting up the gate plate adjustment mechanism in the present invention, when it is necessary to adjust the flow rate of each regulating ball valve body, the adjustment motor drives the adjustment rack to rotate until it meshes with one of the regulating gears, and then the electric slider drives the regulating gate plate to slide up and down to achieve the adjustment of the flow rate of a single regulating ball valve body. After that, the adjustment rack returns to its original position to adjust the flow rate of the next regulating ball valve body, thereby realizing the automatic adjustment of the flow rate of each shunt; 3. By setting up the switch gear ring in the present invention, when it is necessary to urgently close each regulating ball valve body, the electric slider drives the switch gear ring to mesh with each driven gear, and the adjustment shaft drives the regulating ball to rotate to close all the regulating ball valve bodies, achieving the emergency closing of the regulating ball valve bodies. When it is necessary to open them, the switch gear ring and the adjustment rack retract and reset to synchronously open all the regulating ball valve bodies; 4. By setting up the locking gear ring in the present invention, in the initial state and when the switch gear ring resets, the locking gear ring will replace the switch gear ring to mesh with each driven gear. At the same time, since the driven gears are limited by each reset spring rod, each regulating ball is locked, effectively preventing the regulating ball from deflecting automatically under the influence of water flow and vibration. By setting up the shunt tee, the shunt tee can provide another water conveyance route for each sub-water flow, enabling the original water flow to be directly divided instead of converging, thereby realizing multiple water conveyance methods.

[0020] As Figures 1 to 10 shown, the gate-adjusting ball valve includes a water inlet pipe 1 and a water outlet pipe 2. As Figure 1 、 Figure 2 shown, a same adjusting housing 3 is fixedly sleeved between the water inlet pipe 1 and the water outlet pipe 2. One ends of the water inlet pipe 1 and the water outlet pipe 2 located inside the adjusting housing 3 are respectively fixedly installed with a water inlet manifold pipe 4 and a water outlet manifold pipe 5. A plurality of evenly distributed water inlet shunt pipes 6 and water outlet shunt pipes 7 are respectively fixedly installed on the circumferences of the water inlet manifold pipe 4 and the water outlet manifold pipe 5. The positions of the plurality of water inlet shunt pipes 6 respectively correspond to the positions of the plurality of water outlet shunt pipes 7. A same adjusting ball valve body 8 is fixedly installed between the water inlet shunt pipe 6 and the water outlet shunt pipe 7 at the same location.

[0021] As Figure 1 、 Figure 2 shown, specifically, a shunt tee 32 is fixedly installed between the water outlet shunt pipe 7 and the adjusting ball valve body 8 at the same location. One end of the shunt tee 32 extends to the outside of the adjusting housing 3 and is screwed with a sealing screw cap 33.

[0022] More specifically, by providing the shunt tee 32, the shunt tee 32 can provide another water conveyance route for each split water flow, so that the original water flow is directly split instead of converging, thereby realizing multiple water conveyance methods.

[0023] As Figure 4 、 Figure 5 shown, specifically, valve pipe sleeves 9 are fixedly installed on the adjusting ball valve body 8. Switch valve pipes 10 are rotatably installed inside the valve pipe sleeves 9. One end of the switch valve pipe 10 extends to the inside of the adjusting ball valve body 8 and is fixedly installed with an adjusting valve ball 11. As Figure 6 、 Figure 7As shown, an adjusting ball core 12 is fixedly installed inside the regulating valve ball 11. The adjusting ball core 12 includes a front baffle 1201. On one side of the front baffle 1201, two symmetrically arranged rear baffles 1202 are fixedly installed. The adjusting gate 14 is slidably installed between the front baffle 1201 and the rear baffle 1202.

[0024] More specifically, by setting the front baffle 1201 and the rear baffle 1202, the adjusting ball core 12 and the regulating valve ball 11 are assembled by full welding. The V-shaped front baffle 1201 with a larger area faces the water inflow side, which can improve the structural strength of the adjusting ball core 12. At the same time, in cooperation with the adjusting gate 14, when adjusting the regulating valve ball 11, it can ensure a stable linear change in flow rate. Compared with the traditional flow rate adjustment method of the valve ball, the accuracy and stability of flow rate adjustment are greatly improved.

[0025] As Figure 5 、 Figure 11 As shown, guide thread grooves are respectively opened inside the bottom ends of the on-off valve pipes 10. Adjusting screw pipes 35 are respectively screwed inside the bottom ends of the on-off valve pipes 10. An adjusting flower-shaped sliding rod 36 is slidably installed inside the adjusting screw pipe 35. The top end of the adjusting flower-shaped sliding rod 36 is fixedly installed with an adjusting outer sliding rod 13. The bottom end of the adjusting screw pipe 35 extends into the inside of the regulating valve ball 11 and is rotatably installed with an adjusting gate 14. The adjusting gate 14 is slidably installed inside the adjusting ball core 12.

[0026] More specifically, when this gate-adjusting ball valve is in use, the water flow will be divided by the water inlet pipe 1 and the water inlet manifold pipe 4, and then enter each water inlet branch pipe 6. Then, it will be re-converged into the water outlet manifold pipe 5 through the regulating ball valve body 8, the branch three-way pipe 32, and the water outlet branch pipe 7, and finally be discharged into the pipeline through the water outlet pipe 2. The water flow is first divided, and after the flow rate is adjusted by each regulating ball valve body 8, it is re-converged and transported together. Through the joint adjustment of multiple regulating ball valve bodies 8, the adjustment accuracy of the flow rate is doubled. By respectively controlling the positions of the adjusting gates 14 inside each regulating ball valve body 8, high-precision adjustment of the flow rate can be achieved, meeting the accuracy requirements of secondary network balance adjustment.

[0027] A gate-adjusting mechanism is arranged on one side of the water inlet manifold pipe 4 for controlling the sliding of each adjusting gate 14 in the adjusting ball core 12, such as Figure 2 、 Figure 8As shown, specifically, the gate adjustment mechanism includes an adjusting motor 16 fixedly mounted on one side of the water inlet manifold 4, the output shaft of the adjusting motor 16 drives the installation of a horizontally arranged adjusting shaft 17, one end of the adjusting shaft 17 is fixedly mounted with a flower-shaped shaft 18, one side of the water outlet manifold 5 is fixedly mounted with a hanging disk 19, one side of the hanging disk 19 is fixedly mounted with a hanging sleeve 20, one end of the flower-shaped shaft 18 is rotatably connected to the hanging sleeve 20, a linear guide 21 is fixedly mounted on the side wall of the adjusting shaft 17, an electric slider 22 is driven and installed on the linear guide 21, and an adjusting gear rod 23 is fixedly mounted on the electric slider 22, as shown in FIG. Figure 4 As shown, one end of the regulating outer sliding rod 13 located outside the switch valve tube 10 is slidably sleeved with an regulating gear 15 that is adapted to the regulating gear rod 23 .

[0028] In this embodiment, the outer ends of the water inlet pipe 1 and the water outlet pipe 2 can be connected to water pressure gauges respectively to provide numerical references for the operation of the gate adjustment mechanism. The drive of the electric slider 22 is mainly achieved by the electromagnetic principle. The stator (iron core and coil) and the mover (electric slider 22) of the linear motor are arranged inside the adjustment housing 3. The stator is energized to generate a magnetic field, and the mover moves along the linear guide rail 21 under the action of the magnetic force. The movement direction of the electric slider 22 can be changed by changing the direction of the current. The high-load electric slider can carry hundreds of kilograms of objects for movement, which is sufficient to complete the adjustment and switching operations of the regulating ball valve.

[0029] More specifically, by setting up a gate adjustment mechanism, when it is necessary to adjust the flow of each regulating ball valve body 8, the regulating motor 16 drives the regulating shaft 17 to rotate, thereby driving the regulating gear rod 23 to rotate to engage with one of the regulating gears 15, and then the electric slider 22 drives the regulating gear rod 23 to move along the linear guide rail 21, thereby driving the regulating gear 15 to rotate through the regulating gear rod 23, and then driving the regulating outer slide rod 13 to rotate, so that it drives the regulating solenoid 35 to rotate on the switch valve tube 10 through the regulating flower-shaped slide rod 36, and then under the action of the guide thread groove The spiral is lifted and lowered, thereby driving the regulating gate 14 inside the regulating ball core 12 to slide up and down. When the regulating gate 14 slides upward to the top of 11, the communication area of the regulating ball core 12 can be increased to 30% at most, thereby realizing the flow regulation of a single regulating ball valve body 8. After that, the regulating shaft 17 drives the regulating gear rod 23 to rotate and disengage from the current regulating gear 15. The electric slider 22 drives the regulating gear rod 23 to reset. After that, the above operation is repeated to adjust the flow of the next regulating ball valve body 8, thereby realizing automatic adjustment of each diversion flow.

[0030] like Figure 4 As shown, specifically, the side walls of the adjusting gear 15 are all arc-shaped.

[0031] In this embodiment, the side wall of the tooth valley of the adjusting gear 15 and the side wall of the tooth tip of the meshing tooth are both concave arcs, and the side wall of the tooth valley of the adjusting tooth rod 23 and the side wall of the tooth tip of the meshing tooth are convex arcs that are adapted to each other.

[0032] More specifically, the inner and outer arc structures of the adjusting gear 15 and the adjusting tooth rod 23 are beneficial to the relative rotational engagement of the adjusting gear 15 and the adjusting tooth rod 23.

[0033] As Figure 8 shown, a switch tooth ring 25 is slidably sleeved on the flower-shaped shaft 18. As Figure 2 shown, a plurality of uniformly distributed return spring rods 26 are fixedly installed on one side of the suspension disc 19. As Figure 9 shown, a same bearing ring 34 is fixedly installed at the telescopic ends of the plurality of return spring rods 26, and the switch tooth ring 25 is rotatably connected to the bearing ring 34. As Figure 1 、 Figure 3 shown, a plurality of uniformly distributed suspension brackets 27 are fixedly installed inside the adjusting housing 3. Horizontally arranged switch rods 28 are rotatably installed on the suspension brackets 27. The plurality of switch rods 28 are respectively located on one side of the plurality of adjusting ball valve bodies 8. As Figure 3 、 Figure 4 shown, a switch bevel gear 24 is fixedly sleeved at one end of the switch rod 28 and at the end of the switch valve pipe 10 located outside the valve pipe sleeve 9. The two switch bevel gears 24 at the same location are meshed with each other. A driven gear 29 is fixedly sleeved at the other end of the switch rod 28. The plurality of driven gears 29 are uniformly distributed along the axis of the flower-shaped shaft 18 and are adapted to the switch tooth ring 25.

[0034] More specifically, by setting the switch tooth ring 25, when it is necessary to urgently close each adjusting ball valve body 8, the adjusting tooth rod 23 rotates and does not mesh with any one of the adjusting gears 15. Then, the electric slider 22 drives the adjusting tooth rod 23 to move towards the switch tooth ring 25 until it contacts the switch tooth ring 25 and drives the switch tooth ring 25 to slide along the flower-shaped shaft 18 until the switch tooth ring 25 meshes with each driven gear 29. At this time, the adjusting tooth rod 23 is misaligned with each adjusting gear 15. The adjusting shaft 17 drives the flower-shaped shaft 18 to rotate, thereby driving each driven gear 29 to rotate synchronously. Thus, the switch valve pipes 10 and the regulating valve balls 11 inside the adjusting ball valve bodies 8 are driven to rotate through the switch rods 28 and the switch bevel gears 24, so as to synchronously close all the adjusting ball valve bodies 8 and realize the emergency closing of the adjusting ball valve bodies 8. When it is necessary to open, the switch tooth ring 25 and the adjusting tooth rod 23 are retracted and reset to synchronously open all the adjusting ball valve bodies 8.

[0035] As Figure 9 shown, specifically, a locking tooth ring 30 is fixedly sleeved on the bearing ring 34, and the plurality of driven gears 29 are all meshed with the locking tooth ring 30.

[0036] In this embodiment, the bearing ring 34 is divided into a fixed ring and a rotating ring. The fixed ring is fixedly connected to the telescopic end of the return spring rod 26 and remains stationary. The locking gear ring 30 is fixedly sleeved on the fixed ring. The rotating ring can rotate around the axis of the bearing ring 34, and the switch gear ring 25 is fixedly connected to the rotating ring.

[0037] More specifically, by setting the locking gear ring 30, when in the initial state and when the switch gear ring 25 is reset under the elastic force of the return spring rod 26, the locking gear ring 30 will engage with each driven gear 29 instead of the switch gear ring 25. At the same time, since the driven gears 29 are limited by the respective return spring rods 26, the locking gear ring 30 limits each driven gear 29, and further locks each regulating valve ball 11, effectively preventing the regulating valve balls 11 from deflecting by themselves under the influence of water flow and vibration.

[0038] As Figure 1 shown, a plurality of uniformly distributed maintenance door panels 31 are rotatably installed on the circumferential side of the adjustment housing 3.

[0039] More specifically, by setting the maintenance door panels 31, it is convenient for the staff to lubricate and maintain the various gear components inside the adjustment housing 3.

[0040] In summary: When the gate-adjusting ball valve is in use, the water flow will be divided by the water inlet pipe 1 and the water inlet manifold pipe 4, and then enter each water inlet branch pipe 6. Then, it will be re-converged into the water outlet manifold pipe 5 through the regulating ball valve body 8, the branch three-way pipe 32, and the water outlet branch pipe 7, and finally be discharged into the pipeline through the water outlet pipe 2. The water flow is first divided, and after the flow rate is adjusted by each regulating ball valve body 8, it is converged together and re-transported. Through the joint adjustment of multiple regulating ball valve bodies 8, the adjustment accuracy of the flow rate is doubled. Thus, by respectively controlling the position of the regulating gate 14 in each regulating ball valve body 8, high-precision adjustment of the flow rate can be achieved, meeting the accuracy requirements of secondary network balance adjustment. By setting up the gate adjustment mechanism, when it is necessary to adjust the flow rate of each regulating ball valve body 8, the adjusting motor 16 drives the adjusting shaft 17 to rotate, thereby driving the adjusting rack 23 to rotate and engage with one of the adjusting gears 15. Then, the electric slider 22 drives the adjusting rack 23 to move along the linear guide rail 21, thereby driving the adjusting gear 15 to rotate through the adjusting rack 23. Furthermore, it drives the adjusting outer slide rod 13 to rotate, and it makes the adjusting screw tube 35 rotate in the switching valve tube 10 through the adjusting flower-shaped slide rod 36. Then, under the action of the guiding thread groove, it performs spiral lifting, thereby driving the regulating gate 14 inside the regulating ball core 12 to slide up and down. When the regulating gate 14 slides upward to the top inside of 11, the communication area of the regulating ball core 12 can be increased to a maximum of 30%, thereby realizing the flow rate adjustment of a single regulating ball valve body 8. After that, the adjusting shaft 17 drives the adjusting rack 23 to rotate and disengage from the current adjusting gear 15, and the electric slider 22 drives the adjusting rack 23 to reset. Then, by repeating the above operations, the flow rate of the next regulating ball valve body 8 can be adjusted, thereby realizing the automatic adjustment of the flow rate of each branch. By setting up the switching gear ring 25, when it is necessary to urgently close each regulating ball valve body 8, the adjusting rack 23 rotates and does not engage with any of the adjusting gears 15. Then, the electric slider 22 drives the adjusting rack 23 to move towards the switching gear ring 25 until it contacts the switching gear ring 25 and drives the switching gear ring 25 to slide along the flower-shaped shaft 18 until the switching gear ring 25 engages with each driven gear 29. At this time, the adjusting rack 23 is misaligned with each adjusting gear 15. The adjusting shaft 17 drives the flower-shaped shaft 18 to rotate, thereby driving each driven gear 29 to rotate synchronously. Thus, through the switching rod 28 and the switching bevel gear 24, each switching valve tube 10 and the regulating valve ball 11 inside the regulating ball valve body 8 are driven to rotate, thereby synchronously closing all the regulating ball valve bodies 8 and realizing the emergency closing of the regulating ball valve body 8. When it is necessary to open, the switching gear ring 25 and the adjusting rack 23 are retracted and reset to synchronously open all the regulating ball valve bodies 8. The inner and outer arc structures of the adjusting gear 15 and the adjusting rack 23 are beneficial to the relative rotational engagement between the adjusting gear 15 and the adjusting rack 23. By setting up the locking gear ring 30, in the initial state and when the switching gear ring 25 is reset under the elastic force of the reset spring rod 26, the locking gear ring 30 will engage with each driven gear 29 instead of the switching gear ring 25.Meanwhile, since the driven gear 29 is limited by each reset spring rod 26, the locking gear ring 30 limits each driven gear 29, and further locks each regulating valve ball 11, effectively preventing the regulating valve ball 11 from deflecting by itself under the influence of water flow and vibration. By providing the shunt tee 32, the shunt tee 32 can provide another water conveyance route for each sub-water flow, so that the original water flow is directly shunted and no longer converges, thus realizing various water conveyance methods. By providing the maintenance door panel 31, the maintenance door panel 31 facilitates the staff to lubricate and maintain each gear component inside the adjustment housing 3. By providing the front baffle 1201 and the rear baffle 1202, the regulating ball core 12 and the regulating valve ball 11 are assembled by means of full welding. The front baffle 1201 with a larger V-shaped outer shape faces the water inflow side, which can improve the structural strength of the regulating ball core 12. At the same time, in cooperation with the regulating gate 14, when adjusting the regulating valve ball 11, it can ensure a stable linear change in flow rate. Compared with the traditional flow rate adjustment method of the valve ball, the accuracy and stability of flow rate adjustment are greatly improved.
