Description

Technical Field

[0001] The present invention relates to the technical field of ball valves, in particular to a gate regulating ball valve. Background Art

[0002] A gate ball valve refers to a ball valve with a gate hole connected to the valve hole on the valve ball, and a gate installed in the gate hole. The valve ball controls opening and closing, and the gate controls the flow. Due to its simple structure and good sealing performance, the gate ball valve is widely used in water supply and drainage systems such as domestic water, heating systems, and mines.

[0003] When dealing with the problem of balancing the two networks of the heating system, the existing gate ball valve has to use a conservative friction coefficient in the calculation of the resistance along the way due to factors such as the service life of each pipeline network, scaling and corrosion inside the pipeline. As a result, after the orifice valve modification is implemented in the entire pipeline network, nearly 30% of the orifice plate apertures need to be adjusted. The current gate ball valve is difficult to have the precise adjustment performance that meets the needs of balancing the two networks. In addition, since the gate ball valve opens and closes by cutting off the fluid by the up and down movement of the gate, when the gate valve is closed, the gate is usually subjected to a large fluid pressure on the inflow side of the fluid medium and is easily damaged. For this reason, a gate regulating ball valve is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that the current gate ball valve is difficult to have the precise adjustment performance that meets the requirements of two-network balance adjustment, and because the opening and closing of the gate ball valve is based on the up and down movement of the gate to cut off the fluid, usually when the gate valve is closed, the gate is subjected to a large fluid pressure on the inflow side of the fluid medium and is easily damaged. The present invention provides a gate regulating ball valve.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

The same regulating ball valve body is fixedly installed between the water inlet manifold and the outlet water diverter located at the same place. A diversion tee is fixedly installed between the water outlet manifold and the regulating ball valve body located at the same place.

[0011] Furthermore, the side walls of the adjusting gear are all arc-shaped.

[0012] Furthermore, a switch gear ring is slidably sleeved on the flower-shaped shaft, a plurality of evenly distributed return spring rods are fixedly installed on one side of the suspension plate, and the telescopic ends of the plurality of return spring rods are fixedly installed with the same bearing ring, the switch gear ring is rotatably connected to the bearing ring, and a plurality of evenly distributed suspension brackets are fixedly installed inside the adjusting shell, and horizontally arranged switch rods are rotatably installed on the suspension brackets, and 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 the end of the switch valve pipe located outside the valve pipe sleeve are fixedly sleeved with a switch bevel gear, and the two switch bevel gears located at the same place are meshed with each other, and the other end of the switch rod is fixedly sleeved with a driven gear, and the plurality of driven gears are evenly distributed along the axis of the flower-shaped shaft and adapted to the switch gear ring.

[0019] 4. The present invention provides a locking gear ring so that in the initial state and when the switch gear ring is reset, the locking gear ring will replace the switch gear ring to engage with each driven gear. At the same time, since the driven gear is limited by each reset spring rod, each regulating valve ball is locked, effectively preventing the regulating valve ball from being deflected by the water flow and vibration. By providing a diversion tee, the diversion tee can provide another water delivery route for each diversion flow, so that the original water flow is directly diverted instead of converging, thereby realizing multiple water delivery methods.

Therefore, they cannot be understood as limitations on the present invention.

[0036] like Figures 1 to 10 As shown, the gate regulating ball valve includes an inlet pipe 1 and an outlet pipe 2. Figure 1 、 Figure 2 As shown, the same regulating shell 3 is fixedly connected between the water inlet pipe 1 and the water outlet pipe 2, and the water inlet manifold 4 and the water outlet manifold 5 are fixedly installed at one end of the water inlet pipe 1 and the water outlet pipe 2 located inside the regulating shell 3, and a plurality of evenly distributed inlet water diverter pipes 6 and outlet water diverter pipes 7 are fixedly installed on the circumference of the water inlet manifold 4 and the water outlet manifold 5, respectively. The positions of the plurality of inlet water diverter pipes 6 correspond to the positions of the plurality of outlet water diverter pipes 7, and the same regulating ball valve body 8 is fixedly installed between the inlet water diverter pipe 6 and the outlet water diverter pipe 7 located at the same place.

[0037] like Figure 1 、 Figure 2 As shown, specifically, a diversion tee 32 is fixedly installed between the outlet diversion pipe 7 and the regulating ball valve body 8 located at the same place, and one end of the diversion tee 32 extends to the outside of the regulating shell 3 and is screwed with a sealing screw cover 33.

[0038] More specifically, by providing the diversion tee 32 , the diversion tee 32 can provide another water delivery route for each diversion flow, so that the original water flow is directly diverted instead of converging, thereby realizing multiple water delivery methods.

[0039] like Figure 4 、 Figure 5As shown, specifically, a valve tube sleeve 9 is fixedly installed on the regulating ball valve body 8, and a switch valve tube 10 is rotatably installed inside the valve tube sleeve 9. One end of the switch valve tube 10 extends to the interior of the regulating ball valve body 8 and is fixedly installed with a regulating valve ball 11. Figure 6 、 Figure 7 As shown, the regulating ball core 12 is fixedly installed inside the regulating valve ball 11, and the regulating ball core 12 includes a front baffle 1201, and two symmetrically arranged rear baffles 1202 are fixedly installed on one side of the front baffle 1201, and the regulating gate 14 is slidably installed between the front baffle 1201 and the rear baffle 1202.

[0040] More specifically, by setting the front baffle 1201 and the rear baffle 1202, the regulating 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 inflow side of the water flow, which can improve the structural strength of the regulating ball core 12. At the same time, it cooperates with the regulating gate plate 14 to ensure that the flow rate changes stably and linearly when adjusting the valve ball 11. Compared with the flow regulation method of the traditional valve ball, the accuracy and stability of the flow regulation are greatly improved.

[0041] like Figure 5 、 Figure 11 As shown, a guide thread groove is opened inside the bottom end of the switch valve tube 10, and an adjusting screw 35 is screwed inside the bottom end of the switch valve tube 10. An adjusting flower-shaped slide rod 36 is slidably installed inside the adjusting screw 35, and an adjusting outer slide rod 13 is fixedly installed on the top of the adjusting flower-shaped slide rod 36. The bottom end of the adjusting screw 35 extends to the inside of the regulating valve ball 11 and is rotatably installed with an adjusting gate plate 14, and the adjusting gate plate 14 is slidably installed inside the regulating ball core 12.

[0042] More specifically, when the gate regulating ball valve is in use, the water flow will be diverted through the water inlet pipe 1 and the water inlet manifold 4, and then enter each water inlet manifold 6, and then re-converge to the water outlet manifold 5 through the regulating ball valve body 8, the diversion tee 32 and the water outlet manifold 7, and finally discharged into the pipeline through the water outlet pipe 2. The water flow is first diverted, and after the flow is adjusted by each regulating ball valve body 8, it is gathered together and re-transmitted. Through the joint adjustment of multiple regulating ball valve bodies 8, the flow adjustment accuracy is doubled, thereby controlling the position of the regulating gate 14 in each regulating ball valve body 8 respectively, and achieving high-precision adjustment of the flow, meeting the accuracy requirements of the two-network balance adjustment.

[0043] A gate regulating mechanism is provided on one side of the water inlet manifold 4 for controlling the sliding of each regulating gate 14 in the regulating ball core 12. 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 .

[0044] 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.

[0045] 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.

[0046] like Figure 4 As shown, specifically, the side walls of the adjusting gear 15 are all arc-shaped.

[0047] In this embodiment, the tooth valley sidewalls of the adjusting gear 15 and the tooth top sidewalls of the meshing teeth are both concave arcs, and the tooth valley sidewalls of the adjusting gear rod 23 and the tooth top sidewalls of the meshing teeth are matched with convex arcs.

[0048] More specifically, the inner and outer arc structures of the adjusting gear 15 and the adjusting gear rod 23 facilitate the relative rotational engagement between the adjusting gear 15 and the adjusting gear rod 23 .

[0049] like Figure 8 As shown, a switch gear ring 25 is slidably sleeved on the flower-shaped shaft 18, as shown in FIG. Figure 2 As shown, a plurality of evenly distributed return spring rods 26 are fixedly mounted on one side of the suspension plate 19, as shown in FIG. Figure 9 As shown, the telescopic ends of the multiple return spring rods 26 are fixedly mounted with the same bearing ring 34, and the switch gear ring 25 is rotatably connected to the bearing ring 34, as shown in FIG. Figure 1 、 Figure 3 As shown, a plurality of evenly distributed suspension brackets 27 are fixedly installed inside the regulating housing 3, and a horizontally arranged switch rod 28 is rotatably mounted on each of the suspension brackets 27. The plurality of switch rods 28 are respectively located on one side of the plurality of regulating ball valve bodies 8, as shown in FIG. Figure 3 、 Figure 4 As shown, one end of the switch rod 28 and the end of the switch valve tube 10 located outside the valve tube sleeve 9 are fixedly sleeved with a switch bevel gear 24, and the two switch bevel gears 24 located at the same place are meshed with each other. The other end of the switch rod 28 is fixedly sleeved with a driven gear 29, and multiple driven gears 29 are evenly distributed along the axis of the flower-shaped shaft 18 and are adapted to the switch gear ring 25.

[0050] More specifically, by providing the switch gear ring 25, when it is necessary to perform emergency closing on each regulating ball valve body 8, the regulating gear rod 23 rotates and does not mesh with any regulating gear 15, and then the electric slider 22 drives the regulating gear rod 23 to move toward the switch gear ring 25 until it contacts the switch gear ring 25 and drives the switch gear ring 25 to slide along the flower-shaped shaft 18 until the switch gear ring 25 meshes with each driven gear 29. At this time, the regulating gear rod 23 is misaligned with each regulating gear 15, and the regulating shaft 17 drives the flower-shaped shaft 18 to rotate, thereby driving each driven gear 29 to rotate synchronously, thereby driving each switch valve tube 10 and the regulating valve ball 11 inside the regulating ball valve body 8 to rotate through the switch rod 28 and the switch bevel gear 24, thereby closing all the regulating ball valve bodies 8 synchronously, realizing emergency closing of the regulating ball valve body 8, and when it needs to be opened, the switch gear ring 25 and the regulating gear rod 23 retreat and reset to open all the regulating ball valve bodies 8 synchronously.

[0051] like Figure 9 As shown, specifically, a locking gear ring 30 is fixedly sleeved on the bearing ring 34 , and a plurality of driven gears 29 are all engaged with the locking gear ring 30 .

[0052] 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, and the rotating ring can rotate around the axis of the bearing ring 34. The switch gear ring 25 is fixedly connected to the rotating ring.

[0053] More specifically, by providing a locking gear ring 30, in the initial state and when the switch gear ring 25 is reset under the elastic force of the reset spring rod 26, the locking gear ring 30 will replace the switch gear ring 25 and engage with each driven gear 29. At the same time, since the driven gear 29 is limited by each reset spring rod 26, the locking gear ring 30 limits each driven gear 29, thereby locking each regulating valve ball 11, effectively preventing the regulating valve ball 11 from being affected by water flow and vibration and deflecting itself.

[0054] like Figure 1 As shown, a plurality of evenly distributed maintenance door panels 31 are rotatably mounted on the circumference of the adjustment housing 3 .

[0055] More specifically, by providing the maintenance door panel 31 , the maintenance door panel 31 makes it easier for workers to perform oiling and maintenance on the various gear components inside the adjustment housing 3 .

[0056] In summary: when the gate regulating ball valve is in use, the water flow will be diverted through the water inlet pipe 1 and the water inlet manifold 4, and then enter each water inlet manifold 6, and then re-converge to the water outlet manifold 5 through the regulating ball valve body 8, the diversion tee 32 and the water outlet manifold 7, and finally discharged into the pipeline through the outlet pipe 2. The water flow is first diverted, and after the flow is adjusted by each regulating ball valve body 8, it is gathered together and re-transmitted. Through the joint adjustment of multiple regulating ball valve bodies 8, the flow adjustment accuracy is doubled, so that the position of the regulating gate 14 in each regulating ball valve body 8 is controlled separately, and high-precision adjustment of the flow can be achieved to meet the accuracy requirements of the two-network balance adjustment. By setting the gate adjustment mechanism, when it is necessary to adjust the flow of each regulating ball valve body 8, the adjusting motor 16 The drive adjustment shaft 17 rotates, thereby driving the adjustment gear rod 23 to engage with one of the adjustment gears 15, and then the electric slider 22 drives the adjustment gear rod 23 to move along the linear guide rail 21, thereby driving the adjustment gear 15 to rotate through the adjustment gear rod 23, and then driving the adjustment outer slide rod 13 to rotate, so that it drives the adjustment screw 35 to rotate on the switch valve tube 10 through the adjustment flower-shaped slide rod 36, and then spirally lifts and lowers under the action of the guide thread groove, thereby driving the adjustment gate 14 inside the adjustment ball core 12 to slide up and down. When the adjustment gate 14 slides upward to the top inside of 11, the communication area of ​​the adjustment ball core 12 can be increased to 30% at most, thereby realizing the flow adjustment of a single adjustment ball valve body 8, and then the adjustment shaft 17 drives the adjustment 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, and then repeat the above operation to adjust the flow of the next regulating ball valve body 8, thereby realizing automatic adjustment of each diversion flow, by setting the switch gear ring 25, so that when it is necessary to emergency close each regulating ball valve body 8, the regulating gear rod 23 rotates and does not mesh with any regulating gear 15, and then the electric slider 22 drives the regulating gear rod 23 to move toward the switch gear ring 25 until it contacts the switch gear ring 25 and drives the switch gear ring 25 to slide along the flower-shaped shaft 18 until the switch gear ring 25 meshes with each driven gear 29. At this time, the regulating gear rod 23 is misaligned with each regulating gear 15, and the regulating shaft 17 drives the flower-shaped shaft 18 to rotate, thereby driving each The driven gears 29 rotate synchronously, thereby driving the switch valve tubes 10 and the regulating valve balls 11 inside the regulating ball valve body 8 to rotate through the switch rod 28 and the switch bevel gear 24, thereby closing all the regulating ball valve bodies 8 synchronously, realizing the emergency closing of the regulating ball valve body 8. When it is necessary to open, the switch gear ring 25 and the regulating gear rod 23 retreat and reset to open all the regulating ball valve bodies 8 synchronously. The inner and outer arc structures of the regulating gear 15 and the regulating gear rod 23 are conducive to the relative rotational engagement of the regulating gear 15 and the regulating gear rod 23. By providing a locking gear ring 30, in the initial state and when the switch gear ring 25 is reset under the elastic force of the reset spring rod 26, the locking gear ring 30 will replace the switch gear ring 25 to engage with each driven gear 29.At the same time, since the driven gear 29 is limited by each return spring rod 26, the locking gear ring 30 limits each driven gear 29, thereby locking each regulating valve ball 11, effectively preventing the regulating valve ball 11 from being deflected by the water flow and vibration. By setting the diversion tee 32, the diversion tee 32 can provide another water delivery route for each diversion flow, so that the original water flow is directly diverted instead of converging, thereby realizing multiple water delivery methods. By setting the maintenance door plate 31, the maintenance door plate 31 is convenient for the staff to operate the regulating valve. The various gear components inside the housing 3 are lubricated and maintained. By providing a front baffle 1201 and a rear baffle 1202, the regulating ball core 12 and regulating valve ball 11 are assembled using a full-weld method. The larger V-shaped front baffle 1201 faces the water inflow side, which can improve the structural strength of the regulating ball core 12. At the same time, it cooperates with the regulating gate 14 to ensure stable linear flow changes when adjusting the valve ball 11. Compared with the flow regulation method of traditional valve balls, this greatly improves the accuracy and stability of flow regulation.

[0057] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention.
