Description

A metal composite sealing ball valve Technical Field

[0001] This invention relates to the field of ball valve technology, and more specifically to a metal composite sealing ball valve. Background Technology

[0002] A sealing ball valve is a rotary valve that uses a centrally located ball with a channel as its opening and closing element. Its core principle lies in the tight contact between the ball and the valve seat, which completely cuts off the flow of media when closed. Rotating the handle or actuator 90 degrees achieves full opening or full closing. In the open state, the ball's channel is aligned with the pipeline axis, allowing the media to flow through with almost no resistance. In the closed state, rotating the handle 90 degrees causes the ball to rotate, turning its solid part towards the pipeline. The ball's surface presses against the valve seat, forming a seal and blocking the media. When closed, the media pressure pushes the ball against the valve seat, producing... Sufficient sealing pressure is required to achieve zero or minimal leakage. However, in existing sealing ball valves, when the valve is closed, the medium (especially liquid) is trapped inside the valve body cavity. When the medium vaporizes due to increased ambient temperature, the pressure inside the valve cavity rises sharply, far exceeding the pipeline pressure. This can cause valve seat displacement, sealing failure, or even valve body rupture. In addition, in pipeline systems, rapid closure of the ball valve can trigger a huge pressure shock wave, causing impact damage to the pipeline. To address these issues, we propose a metal composite sealing ball valve. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a metal composite sealing ball valve to solve the problems existing in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a metal composite sealing ball valve, comprising a valve tube assembly, the valve tube assembly comprising a central ball tube, a sealing ball installed inside the central ball tube, a movable rocker plate installed inside the bottom of the sealing ball, a drain spring installed at the bottom of the movable rocker plate, a deflection turbine installed at one end of the central ball tube, a spring installed at the bottom of the central ball tube, a U-shaped tube installed at the bottom of the sealing ball, and a convection component installed at one end of the U-shaped tube;

[0005] The sealing sphere uses the cooperation of a movable rocker and a discharge spring to discharge the medium trapped in the sealing sphere. The U-shaped tube uses the linkage of a deflection turbine and a spring to promote the discharge of the medium from the sealing sphere and input the medium into the convection assembly to balance the water pressure shock wave.

[0006] The deflecting turbine includes a connector, a fan plate is mounted on the side of the connector, and a blade is mounted on the inner side of the fan plate. The blade deflects between 0° and 45° with the fan plate. When the spring is at its maximum contraction limit, the blade is parallel to the fan plate, reducing the resistance to medium flow.

[0007] Furthermore, one end of the valve tube assembly is fixedly connected to a power storage component, and the bottom of the power storage component is fixedly connected to a suction component, with one end of the suction component fixedly connected to the bottom end of the valve tube assembly.

[0009] Furthermore, the ball valve assembly includes a sealing ball with a channel cavity on its inner side. A valve stem is fixedly connected to the top of the sealing ball, and a switch handle is fixedly connected to the top of the valve stem. A plate groove is provided on the inner side of the bottom of the sealing ball, and a drain hole is provided at the bottom of the sealing ball, with the drain hole located in the middle of the plate groove. A movable rocker is rotatably connected to the rear end of the plate groove.

[0010] Furthermore, the energy storage component includes an inlet valve pipe, one end of which is fixedly connected to one end of the central ball tube, a transmission component is fixedly connected to the inner side of one end of the inlet valve pipe, one end of the transmission component is fixedly connected to a deflection turbine, and a transmission housing is fixedly connected to the bottom of the inlet valve pipe.

[0011] Furthermore, the transmission assembly includes an isolation housing, a rotating rod 1 rotatably sleeved on one side of the isolation housing, a conical block fixedly connected to the other side of the isolation housing, a bevel gear 1 fixedly connected to one end of the rotating rod 1 and the bevel gear 1 being inside the isolation housing, a rotating rod 2 rotatably sleeved on the bottom of the isolation housing, a bevel gear 2 fixedly connected to the top end of the rotating rod 2 and the bevel gear 2 being located inside the isolation housing, the bevel gear 1 meshing with the bevel gear 2, and a bevel gear 3 fixedly connected to the bottom end of the rotating rod 2.

[0012] Furthermore, one side of the connector is fixedly connected to one end of the rotating rod, and several fan plates are fixedly connected to the side of the connector. The front of the fan plate is provided with a blade groove, and an intermediate shaft is rotatably connected to the inner side of the blade groove. A pin block is fixedly connected to the side of the bottom end of the intermediate shaft, and a rotating blade is fixedly sleeved on the side of the intermediate shaft.

[0013] Furthermore, the bottom of the blade groove is provided with a fan groove, the pin block is located at one end of the fan groove and moves in the fan groove, and a return spring is fixedly connected to the bottom end of the blade, and the bottom end of the return spring is fixedly connected to the bottom end of the blade groove.

[0014] Furthermore, the suction assembly includes a transmission housing, one end of which is fixedly connected to a circular shell, and one end of which is rotatably sleeved with a starting shaft. One end of the starting shaft is fixedly connected to a bevel gear four, which meshes with a bevel gear three and is located inside the transmission housing. The other end of the starting shaft is fixedly connected to a mainspring, the side of which is fixedly sleeved inside the circular shell. One side of the mainspring is fixedly connected to a drive shaft, one end of which is fixedly connected to a fan blade. The other end of the circular shell is fixedly connected to a U-shaped tube, which passes through the inner wall of the U-shaped tube, and the fan blade is located inside the U-shaped tube. One end of the U-shaped tube is fixedly connected to the bottom of the convection assembly, and the other end of the U-shaped tube is fixedly connected to a drain hole.

[0015] Furthermore, the convection assembly includes an annular tube, the bottom of which is fixedly connected to a U-shaped tube, and a plurality of drain pipes are fixedly connected to the inner side of the annular tube, with a one-way valve fixedly sleeved on the inner side of each drain pipe.

[0016] The technical effects and advantages of this invention are as follows:

[0017] 1. When the valve is open, medium flows through the channel of the sealing ball. One end of the movable rocker plate is pushed down by the medium and the pressure of the medium flow, and fits against the plate groove to seal the vent hole. At this time, the medium flows normally in the ball valve. When the valve is closed, the medium trapped in the channel cavity of the sealing ball is in a static state. The pressure at the bottom of the medium is insufficient to maintain the sealing state of the movable rocker plate. Under the action of the discharge spring, the movable rocker plate bounces up, opens the vent hole, and discharges the medium trapped in the cavity of the sealing ball. This process avoids the problem of the medium being trapped in the valve body cavity when the valve is closed. The medium vaporizes due to the rise in ambient temperature, causing the pressure in the valve cavity to rise sharply, far exceeding the pipeline pressure, thereby causing valve seat displacement, sealing failure, or even valve body rupture.

[0018] 2. When the valve is opened, the medium rapidly flows into the inlet pipe. This medium drives the deflector turbine to rotate, and the transmission assembly rotates the starting shaft to tighten the spring. When the spring is at its maximum contraction, the transmission assembly stops rotating, and the deflector turbine also stops. When the valve is closed, the medium in the inlet pipe stops flowing. The deflector turbine loses the rotational stress caused by the flowing medium, causing the rotational stress on the spring from the starting shaft to disappear. The spring elastically releases, causing the drive shaft to rotate rapidly, driving the fan blades to rotate rapidly, creating a negative pressure suction force. This force quickly draws the medium trapped in the sealed ball away, discharges it into the annular pipe, and exits it from the drain pipe. The impact force of the discharged medium collides with the pressure shock wave caused by closing the ball valve, reducing the impact of the medium on the pipeline and avoiding the problem of the huge pressure shock wave caused by rapidly closing the ball valve in the pipeline system, which could cause impact damage to the pipeline.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The metal composite sealing ball valve involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Referring to Figure 1, the present invention provides a metal composite sealing ball valve, including a valve tube assembly 1, one end of which is fixedly connected to a power storage component 2, and the bottom of the power storage component 2 is fixedly connected to a suction component 3, and one end of the suction component 3 is fixedly connected to the bottom end of the valve tube assembly 1.

[0032] In this embodiment, it is necessary to further explain that the valve pipe assembly 1 and the suction assembly 3 prevent the medium from being trapped in the valve body cavity when the valve is closed. The medium vaporizes due to the increase in ambient temperature, causing the pressure in the valve cavity to rise sharply, far exceeding the pipeline pressure, which could lead to valve seat displacement, sealing failure, or even valve body rupture. The power storage assembly 2 and the suction assembly 3 prevent the rapid closure of the ball valve in the pipeline system from causing a huge pressure shock wave that could damage the pipeline. The specific structure and working principle of the above components will be explained in detail later.

[0033] Referring to Figure 2, the valve tube assembly 1 includes a central ball tube 101. One end of the central ball tube 101 is fixedly connected to a valve outlet pipe. A switch handle 102 is rotatably connected to the top end of the central ball tube 101. A ball valve assembly 103 is rotatably sleeved on the inner side of the central ball tube 101. A convection assembly 306 is fixedly connected to the side of the other end of the central ball tube 101.

[0034] Referring to Figures 3 and 4, the ball valve assembly 103 includes a sealing ball 1031, with a channel cavity on the inner side of the sealing ball 1031. A valve stem is fixedly connected to the top of the sealing ball 1031, and a switch handle 102 is fixedly connected to the top of the valve stem. A plate groove is provided on the inner side of the bottom of the sealing ball 1031, and a drain hole is provided at the bottom of the sealing ball 1031, with the drain hole located in the middle of the plate groove. A movable rocker 1032 is rotatably connected to the rear end of the plate groove. Two drain springs 1033 are fixedly connected to the bottom of one end of the movable rocker 1032, and the bottom ends of the two drain springs 1033 are fixedly connected to the front end of the plate groove.

[0035] In this embodiment, it is necessary to specifically explain that when the ball valve is opened, the medium flows rapidly through the channel cavity of the sealing ball 1031. When the medium flows at high speed, it exerts pressure on the pipeline. This pressure squeezes the movable rocker plate 1032, causing it to fit against the plate groove.

[0036] When the valve is open, medium flows through the channel of the sealing ball 1031. One end of the movable rocker 1032 is pushed down by the medium and the pressure of the medium flow, and fits against the plate groove to seal the drain hole. At this time, the medium flows normally in the ball valve. When the valve is closed, the medium trapped in the channel cavity of the sealing ball 1031 is in a static state. The pressure at the bottom of the medium is insufficient to maintain the sealing state of the movable rocker 1032. Under the action of the discharge spring 1033, the movable rocker 1032 bounces up, opens the drain hole, and discharges the medium trapped in the sealing ball cavity. This process avoids the problem of the medium being trapped in the valve body cavity when the valve is closed. The medium vaporizes due to the rise in ambient temperature, causing the pressure in the valve cavity to rise sharply, far exceeding the pipeline pressure, thereby causing valve seat displacement, sealing failure, or even valve body rupture.

[0037] Referring to Figure 5, the power storage component 2 includes an inlet valve pipe 201. One end of the inlet valve pipe 201 is fixedly connected to one end of the central ball tube 101. A transmission component 202 is fixedly connected to the inner side of one end of the inlet valve pipe 201. A deflection turbine 203 is fixedly connected to one end of the transmission component 202. A transmission housing 301 is fixedly connected to the bottom of the inlet valve pipe 201.

[0038] Referring to Figure 6, the transmission assembly 202 includes an isolation housing 2021. A rotating rod 2022 is rotatably sleeved on one side of the isolation housing 2021, and a conical block is fixedly connected to the other side of the isolation housing 2021. A bevel gear 1 is fixedly connected to one end of the rotating rod 2022, and the bevel gear 1 is inside the isolation housing 2021. A rotating rod 2023 is rotatably sleeved at the bottom of the isolation housing 2021. A bevel gear 2 is fixedly connected to the top end of the rotating rod 2023, and the bevel gear 2 is located inside the isolation housing 2021. The bevel gear 1 meshes with the bevel gear 2. A bevel gear 3 is fixedly connected to the bottom end of the rotating rod 2023.

[0039] In this embodiment, it should be specifically noted that the tip of the cone faces the direction of medium inflow, which helps to reduce the resistance of the isolation shell 2021 to the medium flow.

[0040] Referring to Figures 7 and 8, the deflection turbine 203 includes a connector 2031. One side of the connector 2031 is fixedly connected to one end of the rotating rod 2022. A plurality of fan plates 2032 are fixedly connected to the side of the connector 2031. The front of the fan plate 2032 is provided with a blade groove. An intermediate shaft 2033 is rotatably connected to the inner side of the blade groove. A pin is fixedly connected to the side of the bottom end of the intermediate shaft 2033. A rotating blade 2034 is fixedly sleeved on the side of the intermediate shaft 2033. A fan groove is provided at the bottom of the blade groove. The pin is located at one end of the fan groove and moves in the fan groove. The rotating blade 2034 deflects between 0° and 45° with the fan plate 2032. A return spring is fixedly connected to the bottom end of the rotating blade 2034, and the bottom end of the return spring is fixedly connected to the bottom end of the blade groove.

[0041] In this embodiment, it should be specifically noted that there are six fan plates 2032, but not limited to six. The number is set according to actual production needs. The end of the rotating blade 2034 facing the medium entering the ball valve has a pointed and thin design. The rotating blade 2034 is tilted at a 45° angle with the fan plate 2032.

[0042] Referring to Figure 9, the suction assembly 3 includes a transmission housing 301. A circular shell is fixedly connected to one end of the transmission housing 301. A starting shaft 302 is rotatably sleeved on one end of the circular shell. A bevel gear four is fixedly connected to one end of the starting shaft 302. The bevel gear four meshes with the bevel gear three and is located inside the transmission housing 301. A spring 303 is fixedly connected to the other end of the starting shaft 302. The side of the spring 303 is fixedly sleeved inside the circular shell. A drive shaft 304 is fixedly connected to one side of the spring 303. A fan blade is fixedly connected to one end of the drive shaft 304. A U-shaped tube 305 is fixedly connected to the other end of the circular shell. The drive shaft 304 passes through the inner wall of the U-shaped tube 305, and the fan blade is located inside the U-shaped tube 305. One end of the U-shaped tube 305 is fixedly connected to the bottom of the convection assembly 306, and the other end of the U-shaped tube 305 is fixedly connected to the drain hole.

[0043] In this embodiment, it is necessary to further explain that when the medium flows in the inlet valve pipe 201, the deflection turbine 203 rotates, which in turn causes the first rotating rod 2022 to rotate. Under the action of the first and second bevel gears, the second rotating rod 2023 rotates. Similarly, under the action of the third and fourth bevel gears, the starting shaft 302 rotates further, and the mainspring 303 is tightened. When the mainspring 303 is in the maximum compression state and can no longer be tightened, the deflection turbine 203 also stops rotating. At this time, the medium flows... The thrust of the ball valve cannot drive the rotor 2034 to rotate, thus generating lateral pressure on the rotor 2034. When the rotor 2034 is parallel to the water flow direction, that is, parallel to the fan plate 2032, the pressure on both sides of the rotor 2034 is balanced. The thin tip of the rotor 2034 faces the medium flow direction, reducing the medium flow resistance. When the ball valve is closed and there is no medium flow, the pressure on both sides of the rotor 2034 disappears. Under the action of the return spring, the rotor 2034 returns to the 45° angle with the fan plate 2032.

[0044] Referring to Figure 10, the convection assembly 306 includes an annular pipe 3061, the bottom of which is fixedly connected to a U-shaped pipe 305, and a plurality of drain pipes 3062 are fixedly connected to the inner side of the annular pipe 3061. A one-way valve is fixedly sleeved on the inner side of the drain pipe 3062.

[0045] When the valve opens, the medium rapidly flows into the inlet pipe 201. The medium, passing through the inlet pipe 201, drives the deflection turbine 203 to rotate. Using the transmission assembly 202, the starting shaft 302 rotates to tighten the spring 303. When the spring 303 is at its maximum contraction limit, the transmission assembly 202 stops rotating, and the deflection turbine 203 also stops rotating. When the valve closes, the medium in the inlet pipe 201 stops flowing, and the deflection turbine 203 loses the rotational stress caused by the flowing medium, causing the starting shaft 302 to... The rotational stress of the spring 303 also disappears, and the spring 303 is released elastically, which causes the drive shaft 304 to rotate rapidly, driving the fan blades to rotate rapidly, forming a negative pressure suction force, which quickly sucks away the medium trapped in the sealing ball 1031, discharges it into the annular pipe 3061, and discharges it from the drain pipe 3062. The impact force of the discharged medium collides with the pressure shock wave caused by closing the ball valve, which reduces the impact of the medium on the pipeline and avoids the problem of the huge pressure shock wave caused by the rapid closing of the ball valve in the pipeline system, which would cause impact damage to the pipeline.

[0046] It should be specifically noted in this embodiment that 2062 is ten in number, but not limited to ten. It is set according to actual production needs. The spring and the one-way valve are existing technologies, so they will not be described in detail.

[0047] The working principle of this invention is as follows: When the valve is open, medium flows through the channel of the sealing ball 1031. One end of the movable rocker plate 1032 is pushed down by the medium and the pressure of the medium flow, and fits against the plate groove to seal the drain hole. At this time, the medium flows normally in the ball valve. When the valve is closed, the medium trapped in the channel cavity of the sealing ball 1031 is in a static state. The pressure at the bottom of the medium is insufficient to maintain the sealing state of the movable rocker plate 1032. Under the action of the discharge spring 1033, the movable rocker plate 1032 bounces up, opens the drain hole, and discharges the medium trapped in the cavity of the sealing ball. This process avoids the problem that when the valve is closed, the medium is trapped in the valve body cavity and vaporizes due to the rise in ambient temperature, causing the pressure in the valve cavity to rise sharply, far exceeding the pipeline pressure, thereby causing valve seat displacement, sealing failure, or even valve body rupture.

[0048] When the valve opens, the medium rapidly flows into the inlet pipe 201. The medium, passing through the inlet pipe 201, drives the deflection turbine 203 to rotate. Using the transmission assembly 202, the starting shaft 302 rotates to tighten the spring 303. When the spring 303 is at its maximum contraction limit, the transmission assembly 202 stops rotating, and the deflection turbine 203 also stops rotating. When the valve closes, the medium in the inlet pipe 201 stops flowing, and the deflection turbine 203 loses the rotational stress caused by the flowing medium, causing the starting shaft 302 to... The rotational stress of the spring 303 also disappears, and the spring 303 is released elastically, which causes the drive shaft 304 to rotate rapidly, driving the fan blades to rotate rapidly, forming a negative pressure suction force, which quickly sucks away the medium trapped in the sealing ball 1031, discharges it into the annular pipe 3061, and discharges it from the drain pipe 3062. The impact force of the discharged medium collides with the pressure shock wave caused by closing the ball valve, which reduces the impact of the medium on the pipeline and avoids the problem of the huge pressure shock wave caused by the rapid closing of the ball valve in the pipeline system, which would cause impact damage to the pipeline.
