Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a ball valve flow linear regulating device. Background Art

[0002] The ball valve is opened or closed by rotating 90 degrees, with small resistance and straight flow path, which makes it suitable for throttling and controlling flow in some cases. However, the main design purpose of the ball valve is to quickly cut off the fluid or perform switching operations, rather than accurately regulating the flow.

[0003] Chinese patent number CN212360860U provides a ball valve for precise flow control. The key points of its technical solution are that it includes two valve seats and a valve core located between the two valve seats. Both valve seats are respectively provided with a liquid inlet channel and a liquid outlet channel. The valve seat with the liquid outlet channel is provided with a baffle that blocks the liquid outlet channel from the valve core. The baffle is provided with a plurality of control flow holes for connecting the liquid outlet channel and the valve core. The plurality of control flow holes are arranged parallel to the length direction of the liquid outlet channel, which solves the problems of the existing technology that the flow cannot be accurately controlled and the valve seat is easily deformed or damaged due to uneven force.

[0004] A ball valve linear flow control device in the prior art has the following problems: although it solves the problems of the prior art in being unable to accurately control the flow and the valve seat being easily deformed or damaged due to uneven force through a number of flow control holes, it cannot effectively control the water flow when the water pressure in the water pipe is different.

[0005] Therefore, it is urgent to design a ball valve flow linear regulation device to solve the above problems. Utility Model Content

[0006] The utility model aims to solve the shortcomings in the prior art and proposes a ball valve flow linear regulating device.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A ball valve flow linear adjustment device includes a valve body assembly, a pressure stabilizing assembly is slidably connected to the inside of the valve body assembly, a flow control assembly is fixed to the top of the valve body assembly, a control assembly is fixed to one side of the flow control assembly, the flow control assembly includes a meter frame, a perspective plate is fixed to the top of the meter frame, a rotating shaft is rotatably connected to the inside of the meter frame, a clamping hole is opened on one side of the rotating shaft, a pointer is provided on the top of the rotating shaft, and a limit plate is fixed to one side of the rotating shaft.

[0009] Furthermore, the valve body assembly includes a valve body, a different-diameter hole is provided inside the valve body, and a through hole is provided inside the valve body.

[0010] Furthermore, a water outlet pipe is fixed on one side of the valve body, a water inlet pipe is fixed on one side of the valve body, and a valve stem is rotatably connected inside the valve body.

[0011] Furthermore, a valve ball is fixed to one end of the valve stem, a rotating handle is fixed to the other end of the valve stem, and a valve seat is provided inside the valve body.

[0012] Furthermore, the pressure stabilizing assembly includes a guide rod, which is slidably connected to the inside of the valve body, a spring is fixed to one end of the guide rod, and a blocking plate is fixed to the other end of the guide rod.

[0013] Furthermore, the control component includes a shell, which is fixed on one side of the watch frame. A push plate is slidably connected to the inside of the shell, and a pressure handle is slidably connected to the inside of the push plate. A spring 2 is fixed on one side of the pressure handle, and an anti-slip sheet is fixed to the end of the pressure handle.

[0014] Furthermore, a spring three is fixed to one side of the push plate, a top plate is fixed to the end of the spring three, a top rod is fixed to one side of the top plate, and a rolling ball is rotatably connected inside the top rod.

[0015] The beneficial effects of the utility model are:

[0016] 1. Through the flow control component, under the premise that the pressure stabilizing component suppresses or increases the water pressure, water is allowed to enter between two adjacent limit plates through the through hole, and under the restriction of the control component, the adjacent limit plates can only rotate around the rotating axis under the action of water pressure after being filled with water. In this way, the water output and water pressure are effectively controlled.

[0017] 2. Through the control component, the pressure handle is used to squeeze spring 2, so that the anti-slip sheet is retracted into the push plate, and the push plate can squeeze spring 2. When spring 2 is squeezed, the push rod will drive the ball to squeeze the card hole more forcefully, so that when the shaft wants to rotate, greater water pressure is required. Therefore, in this way, the flow of water can be effectively slowed down (because when the accumulated water is not enough, the water pressure generated is not enough to drive the shaft to rotate).

[0018] 3. By setting up a pressure-stabilizing component and utilizing the elasticity of spring 1, the blocking plate can be inserted into the different-diameter hole. At this time, the ball valve is opened. If the water pressure is low, the blocking plate will be pushed out of the different-diameter hole under the action of the water pressure, and finally enter the through hole after the pressure is released, thereby achieving the purpose of pressurization. On the contrary, if the water pressure is high, the elastic force of spring 1 can effectively suppress the rapid influx of high-pressure water into the through hole, thereby achieving the purpose of pressure reduction.

[0019] 4. By setting up the valve body assembly and utilizing the method that the aperture of the reducer hole is larger than the aperture of the valve ball, the gushing water can be effectively depressurized, thereby achieving the purpose of reducing pressure. In addition, in conjunction with the pressure stabilizing assembly, the water pressure can be well controlled, so that the controlled water pressure can effectively control the water flow after passing through the flow control assembly.

[0028] Please also see Figures 1 to 4 A linear flow regulating device for a ball valve includes a valve body assembly 1, a pressure stabilizing assembly 11 being slidably connected inside the valve body assembly 1, a flow control assembly 15 being fixed on the top of the valve body assembly 1, and a control assembly 22 being fixed on one side of the flow control assembly 15, and the flow control assembly 15 including a meter frame 16 having a scale, a perspective plate 17 being fixed on the top of the meter frame 16, through which the scale indicated by the pointer 20 can be seen, a rotating shaft 18 being rotatably connected inside the meter frame 16, and a series of mechanical transmission parts being arranged between the rotating shaft 18 and the pointer 20, a card hole 19 being opened on one side of the rotating shaft 18, a pointer 20 being arranged on the top of the rotating shaft 18, and a limit plate 21 being fixed on one side of the rotating shaft 18, and there being multiple limit plates 21, and the angles between adjacent limit plates 21 being the same, and the limit plate 21 being in slidable but sealed contact with the valve body 2.

[0029] Furthermore, the valve body assembly 1 includes a valve body 2, which is provided with a reducing hole 3 inside the valve body 2, which serves the purpose of reducing pressure. A through hole 4 is provided inside the valve body 2, which serves to guide water flow and re-aggregation. A water outlet pipe 5 is fixed on one side of the valve body 2, and a water inlet pipe 6 is fixed on one side of the valve body 2. A valve stem 7 is rotatably connected inside the valve body 2, and a valve ball 8 is fixed to one end of the valve stem 7, and a turning handle 9 is fixed to the other end of the valve stem 7. The turning handle 9 is used to facilitate the rotation of the valve ball 8 from the outside, and a valve seat 10 is provided inside the valve body 2.

[0030] Furthermore, the pressure stabilizing assembly 11 includes a guide rod 12, which plays a supporting and limiting role. The guide rod 12 is slidably connected to the inside of the valve body 2. A spring 13 is fixed to one end of the guide rod 12. The spring 13 uses elastic force to ensure that the blocking plate 14 is inserted into the reducing hole 3 when the blocking plate 14 is not pressurized. A blocking plate 14 is fixed to the other end of the guide rod 12. The blocking plate 14 can reduce the pressure of high-pressure water and increase the pressure of low-pressure water by blocking the flow of water.

[0031] Furthermore, the control component 22 includes a shell 23, which is fixed to one side of the watch frame 16. A push plate 24 is slidably connected to the inside of the shell 23. The push plate 24 is convenient for squeezing spring three 28, so that the harder the spring three 28 squeezes, the greater the rebound force, so that the force exerted by the ball 31 on the rotating shaft 18 is greater. A pressure handle 25 is slidably connected to the inside of the push plate 24. Pressing the pressure handle 25 can make the anti-slip sheet 27 retract into the push plate 24. A spring two 26 is fixed to one side of the pressure handle 25. The spring two 26 can reset the pressure handle 25 through elastic force. An anti-slip sheet 27 is fixed to the end of the pressure handle 25. A spring three 28 is fixed to one side of the push plate 24. A top plate 29 is fixed to the end of the spring three 28. A push rod 30 is fixed to one side of the top plate 29. The top rod 30 is rotatably connected to the inside of the top rod 30. The ball 31 can reduce the friction between the top rod 30 and the card hole 19.

[0032] Working principle: When in use, first introduce the following points. When the pipe diameter and time remain unchanged, the greater the water pressure, the more water flow. When the water pressure and water flow remain unchanged, the larger the pipe diameter, the smaller the water pressure. Therefore, the specific process and implementation principle of the ball valve for flow regulation is that when the external water pipe enters the valve body 2 through the water inlet pipe 6, the turning handle 9 can drive the valve ball 8 to rotate through the valve stem 7, so that the water flow with unchanged water pressure passes through the valve ball 8 and enters the reducing hole 3, thereby achieving the purpose of pressure reduction. At this time, as the water accumulated in the reducing hole 3 becomes more and more, until it is full, under the action of water pressure The blocking plate 14 can be pushed to move, thereby squeezing the spring 13 through the guide rod 12, so that the water pressure is released and enters the through hole 4. At this time, the water pressure has undergone a pressure adjustment process (the pressure adjustment process is that the pressure is first reduced by the different-diameter hole 3, and then blocked by the blocking plate 14, so that the water pressure reaches a certain level and is released), and enters between the two adjacent limit plates 21 through the through hole 4. At this time, as the space between the two limit plates 21 is filled with water, under the action of water pressure and the low air pressure at the position of the water outlet pipe 5, the high pressure flows to the low pressure, so that the water pressure drives the limit plate 21 to rotate with the shaft 18 To support the rotation, the water flows out through the outlet pipe 5. Here, in order to prevent the water pressure between the adjacent limit plates 21 from reaching a certain level, the ball 31 in the top rod 30 on one side of the top plate 29 is inserted into the card hole 19 through the elastic force of the spring 3 28, thereby exerting a certain resistance to the rotation of the shaft 18. Therefore, the rotation of the shaft 18 can be carried out only when the water pressure reaches a certain level, thereby ensuring the smooth and orderly rotation of the shaft 18. Finally, the shaft 18 drives a series of mechanical transmissions to rotate the pointer 20, thereby rotating the table frame 16 and The value indicated by the pointer 20 can be used to determine how many times the shaft 18 has rotated. The number of times the shaft 18 has rotated can then be multiplied by the number of intervals between the limit plates 21 on the shaft 18, and then multiplied by the amount of water between each interval. Finally, the amount of water flowing out can be determined. Similarly, by pushing the push plate 24, the spring three 28 is squeezed, so that the force exerted by the top rod 30 on the shaft 18 through the ball 31 is greater, so that a greater water pressure is required when the shaft 18 rotates, so that the water accumulates between adjacent limit plates 21 for a longer time to reach a greater water pressure, thereby achieving the purpose of controlling the water flow.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
