Description

Technical Field

[0001] The utility model relates to the technical field of cage throttle valves, in particular to a new type of electric non-turbulent zero-leakage ultra-high pressure cage throttle valve. Background Technique

[0002] A throttle valve is a valve that controls the fluid flow rate by changing the throttle section or throttle length. Specifically, when the fluid passes through the throttle valve, the channel area inside the valve decreases, resulting in an increase in the fluid flow rate, thereby achieving the control of the flow rate. The throttle valve also has the characteristics of a large flow regulation range and a smooth change in pressure difference, which makes it widely used in industrial production.

[0003] Considering that the throttle valve is often adjusted during use and the flow rate needs to be ensured, if the valve is not adjusted in time, the flow rate may change due to an increase in the incoming fluid. When the flow rate changes, turbulence may occur. When turbulence occurs, the fluid cannot flow out smoothly, resulting in internal blockage. When blocked, the internal pressure will increase. Although the equipment itself can withstand high pressure, continuous exposure to a high-pressure environment will also lead to increased wear and reduced service life; in the prior art, when in use, the valve directly blocks the liquid flow, and after repeated use, erosion may cause the sealing performance to deteriorate. Summary of the Invention

[0004] The purpose of the present utility model is to provide a new type of electric non-turbulent zero-leakage ultra-high pressure cage throttle valve to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the present utility model is realized through the following technical solutions:

[0006] The utility model relates to a novel electric non-turbulent zero-leakage ultra-high pressure cage throttle valve, which comprises a valve body. A fluid groove is formed in the inner wall of the valve body. A valve groove is formed in the inner wall of the valve body, and the bottom of the valve groove is communicated with the fluid groove. A pressure relief hole is formed in the inner wall of the valve body. A pressure relief valve is fixedly connected to the inner wall of the pressure relief hole. A valve seat body is fixedly installed on the inner wall of the fluid groove. A fluid hole is formed in the inner wall of the valve seat body, and there are multiple groups of fluid holes which are communicated with the fluid groove. A valve core is slidably connected to the inner wall of the valve seat body. A valve seat pressing sleeve is fixedly connected to the outer wall of the valve core. The outer wall of the valve seat pressing sleeve is slidably connected to the inner wall of the valve groove. A positioning bushing is fixedly connected to the top of the valve seat pressing sleeve. A valve rod body is fixedly connected to the inner wall of the positioning bushing. A valve cover is fixedly installed on the inner wall of the valve groove, and the inner wall of the valve cover is slidably connected to the outer wall of the valve rod body. A bracket is fixedly installed on the outer wall of the valve cover near the top. The inner wall of the bracket is slidably connected to the outer wall of the valve rod body. An intelligent electric actuator is fixedly installed on the top of the bracket. A bearing body is rotatably connected to the inner wall of the bracket. A valve rod nut is rotatably connected to the inner wall of the bracket. A bearing gland is fixedly installed on the inner wall of the bracket. The inner wall of the valve rod nut is threadedly connected to the outer wall of the valve rod body. The outer wall of the valve rod nut is rotatably connected to the inner wall of the bearing gland. The output end of the intelligent electric actuator is fixedly connected to the outer wall of the valve rod nut.

[0007] With the above technical solution, when the fluid flow rate increases, the intelligent electric actuator will receive a signal and start automatically. At the same time, it will perform precise adjustment through calculation. By starting the intelligent electric actuator to drive the valve rod nut to rotate, during the movement of the valve seat pressing sleeve, the fluid holes on the valve seat body are blocked to adjust the flow rate to ensure that the flow rate remains unchanged. During use, the valve seat pressing sleeve does not directly contact the fluid, avoiding the deterioration of the sealing performance caused by fluid erosion and wear. And the adjustment of the flow rate by blocking the number of fluid holes by the valve seat pressing sleeve can increase the adjustment accuracy, and the fluid enters through the fluid holes to disperse the pressure of the fluid, thereby avoiding the generation of turbulence.

[0008] Further, a fixing groove is formed in the outer wall of the valve seat body in contact with the fluid groove, and a first circular sealing ring is fixedly connected to the inner wall of the fixing groove. A sealing groove is formed in the outer wall of the valve cover in contact with the valve groove, and a second circular sealing ring is fixedly connected to the inner wall of the sealing groove. An anti-leakage groove is formed in the outer wall of the valve rod nut in contact with the bearing gland, and a third circular sealing ring is fixedly installed on the inner wall of the anti-leakage groove.

[0009] With the above technical solution, the setting of the first circular sealing ring can increase the sealing performance during use and prevent the fluid from flowing in through the gap. The second circular sealing ring and the third circular sealing ring are used to increase the sealing performance between components to prevent the internal lubricating oil from entering other components and causing damage, and also prevent the lubricating oil from leaking out.

[0010] Furthermore, screw holes are provided at the top of the valve body. The inner wall of each screw hole is threadedly connected with a double-headed bolt, and there are multiple groups of double-headed bolts. Each group of double-headed bolts penetrates through the valve cover. A hexagonal nut is threadedly connected to the outer wall of the double-headed bolt near the top, and there are multiple groups of hexagonal nuts.

[0011] With the above technical solution, the valve body and the valve cover are fixed by the double-headed bolts and the hexagonal nuts. At the same time, the sealing performance between the valve body and the valve cover can also be improved, and it can prevent loosening caused by vibration during equipment operation or when fluid enters.

[0012] Furthermore, grease nipples are provided on the inner wall of the bracket near the valve stem nut, and there are multiple groups of grease nipples.

[0013] With the above technical solution, when the equipment operates for a long time, it will generate heat, and the heat will cause the internal lubricating oil to evaporate. When the internal lubricating oil is lost, it may cause direct contact and friction between the bracket and the valve stem nut, resulting in wear. By setting the grease nipples, lubricating oil can be injected into the interior, and lubricating oil can be injected regularly to reduce the wear of the equipment and increase its service life.

[0014] Furthermore, a packing gland is fixedly installed on the inner wall of the bracket. The bottom of the packing gland is fixedly connected with oil seal packing, and there are two groups of oil seal packing. The bottom of each group of oil seal packing is fixedly connected with a packing gasket.

[0015] With the above technical solution, through the setting of the packing gland and the oil seal packing, it can be avoided that the lubricating oil leaks into the interior of the valve cover. If the lubricating oil enters the interior of the equipment, it may affect the purity of the fluid or cause damage to the equipment.

[0016] Furthermore, screw holes are provided on the outer wall of the valve cover. The inner wall of each screw hole is threadedly connected with an Allen screw, and there are multiple groups of Allen screws. The outer wall of each group of Allen screws penetrates through the bracket.

[0017] With the above technical solution, the valve cover and the bracket are fixedly installed by the Allen screws, making the fit between the valve cover and the bracket closer, improving the sealing performance between the valve cover and the bracket, and avoiding loosening caused by equipment vibration.

[0018] Furthermore, bolt holes are provided at the bottom of the intelligent electric actuator. The outer wall of each bolt hole is threadedly connected with an Allen bolt, and there are multiple groups of Allen bolts. Each group of Allen bolts penetrates through the bracket.

[0019] With the above technical solution, the intelligent electric actuator and the bracket are fixedly installed by hexagon socket head cap screws, which improves the sealing performance between the intelligent electric actuator and the bracket and prevents the internal lubricating oil from leaking into the intelligent electric actuator to avoid damaging the intelligent electric actuator.

[0020] The utility model has the following beneficial effects:

[0021] 1. When the fluid flow rate increases, the intelligent electric actuator will receive a signal and start automatically. At the same time, precise adjustment is carried out through calculation. By starting the intelligent electric actuator to drive the valve stem nut to rotate, during the movement of the valve seat gland, the fluid holes on the valve seat body are blocked to adjust the flow rate to ensure that the flow rate remains unchanged. During use, the valve seat gland does not directly contact the fluid, avoiding the deterioration of the sealing performance caused by fluid erosion and wear. Moreover, by adjusting the flow rate by blocking the number of fluid holes with the valve seat gland, the adjustment accuracy can be increased, and the fluid entering through the fluid holes can disperse the pressure of the fluid, thus avoiding the generation of turbulence.

[0022] 2. When the equipment operates for a long time, it will generate heat, which will cause the evaporation of the internal lubricating oil. When the internal lubricating oil is lost, it may cause direct contact and friction between the bracket and the valve stem nut, resulting in wear. Through the setting of the grease nipple, lubricating oil can be injected into the interior, and lubricating oil can be injected regularly to reduce the wear of the equipment and increase its service life. At the same time, an intelligent oil change device can be set outside the grease nipple to add lubricating oil regularly by recording the equipment usage time.

[0023] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. Description of the Drawings

Specific implementation manner

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-3 As shown, the present invention is a new type of electric non-turbulent zero-leakage ultra-high pressure cage throttle valve, including a valve body 1. A fluid groove is provided on the inner wall of the valve body 1. A valve groove is provided on the inner wall of the valve body 1, and the bottom of the valve groove communicates with the fluid groove. A pressure relief hole is provided on the inner wall of the valve body 1; a pressure relief valve 5 is fixedly connected to the inner wall of the pressure relief hole; a valve seat body 3 is fixedly installed on the inner wall of the fluid groove; a fluid hole is provided on the inner wall of the valve seat body 3, and there are multiple groups of fluid holes, which communicate with the fluid groove. A valve core 4 is slidably connected to the inner wall of the valve seat body 3; a valve seat compression sleeve 6 is fixedly connected to the outer wall of the valve core 4; the outer wall of the valve seat compression sleeve 6 is slidably connected to the inner wall of the valve groove, and a positioning bushing 7 is fixedly connected to the top of the valve seat compression sleeve 6; a valve stem body 8 is fixedly connected to the inner wall of the positioning bushing 7; a valve cover 10 is fixedly installed on the inner wall of the valve groove, and the inner wall of the valve cover 10 is slidably connected to the outer wall of the valve stem body 8. A bracket 13 is fixedly installed on the outer wall of the valve cover 10 near the top; the inner wall of the bracket 13 is slidably connected to the outer wall of the valve stem body 8. An intelligent electric actuator 24 is fixedly installed on the top of the bracket 13. A bearing body 14 is rotatably connected to the inner wall of the bracket 13. A valve stem nut 15 is rotatably connected to the inner wall of the bracket 13. A bearing gland 23 is fixedly installed on the inner wall of the bracket 13; the inner wall of the valve stem nut 15 is threadedly connected to the outer wall of the valve stem body 8, and the outer wall of the valve stem nut 15 is rotatably connected to the inner wall of the bearing gland 23; the output end of the intelligent electric actuator 24 is fixedly connected to the outer wall of the valve stem nut 15.

[0032] In this embodiment, considering that the throttle valve is often adjusted during use and the flow rate needs to be controlled, in the prior art, manual adjustment is usually used. During the use of the throttle valve, someone needs to stay beside it. Once the valve is not adjusted in time, the flow rate may change due to the increase in the incoming fluid. When the flow rate changes, turbulence may occur. When turbulence occurs, the fluid may not flow out smoothly, resulting in internal blockage. When blockage occurs, the internal pressure will increase. Although the equipment itself can withstand high pressure, continuous exposure to a high-pressure environment will also lead to increased loss and reduced service life. In the prior art, a valve is directly used to block the liquid flow. After repeated use, erosion may cause the sealing performance to deteriorate.

[0033] When the fluid flow rate increases, the intelligent electric actuator 24 will receive a signal and start automatically. At the same time, precise adjustment is carried out through calculation. By starting the intelligent electric actuator 24, the valve stem nut 15 is driven to rotate. When the valve stem nut 15 rotates, the valve stem body 8 is driven to move through the thread. When the valve stem body 8 moves, it will push the valve seat bushing 6 to move, and during the movement of the valve seat bushing 6, the fluid holes on the valve seat body 3 are blocked to adjust the flow rate to ensure that the flow rate remains unchanged. During use, the valve seat bushing 6 does not directly contact the fluid, avoiding the deterioration of the sealing performance caused by fluid erosion and wear. Moreover, by adjusting the flow rate by blocking the number of fluid holes by the valve seat bushing 6, the adjustment accuracy can be increased, and the fluid entering through the fluid holes can disperse the pressure of the fluid, thus avoiding the generation of turbulence. When the flow rate needs to be increased, the intelligent electric actuator 24 drives the valve stem nut 15 to rotate in the opposite direction. At this time, the valve stem body 8 will pull the positioning bushing 7 to drive the valve seat bushing 6 to move upward, thereby reducing the blocked fluid holes and increasing the flow rate. When the internal pressure is too high, the pressure relief valve 5 can also be used to relieve the pressure to prevent the reduction of the equipment service life due to excessive pressure.

[0034] Specifically, a fixing groove is provided on the outer wall of the valve seat body 3 in contact with the fluid groove, and a first circular sealing ring 2 is fixedly connected to the inner wall of the fixing groove; a sealing groove is provided on the outer wall of the valve cover 10 in contact with the valve groove, and a second circular sealing ring 9 is fixedly connected to the inner wall of the sealing groove; a leakage prevention groove is provided on the outer wall of the valve stem nut 15 in contact with the bearing cover 23, and a third circular sealing ring 17 is fixedly installed on the inner wall of the leakage prevention groove.

[0035] In this embodiment, the setting of the first circular sealing ring 2 can increase the sealing performance during use to prevent the fluid from flowing in through the gap; the second circular sealing ring 9 and the third circular sealing ring 17 are used to increase the sealing performance between components to prevent the internal lubricating oil from entering other components and causing damage, and also to prevent the lubricating oil from leaking out.

[0036] Specifically, screw holes are provided at the top of the valve body 1. The inner wall of the screw holes is threadedly connected with double-headed bolts 11, and there are multiple groups of double-headed bolts 11; each group of double-headed bolts 11 penetrates through the valve cover 10, and the outer wall of the double-headed bolts 11 near the top is threadedly connected with hexagonal nuts 12, and there are multiple groups of hexagonal nuts 12.

[0037] In this embodiment, the valve body 1 and the valve cover 10 are fixed by the double-headed bolts 11 and the hexagonal nuts 12. At the same time, the sealing performance between the valve body 1 and the valve cover 10 can also be improved, and it can prevent loosening caused by vibration during equipment use or when fluid enters.

[0038] Specifically, grease nipples 22 are provided on the inner wall of the bracket 13 close to the valve stem nut 15, and there are multiple groups of grease nipples 22.

[0039] In this embodiment, when the equipment operates for a long time, it will generate heat, and the heat will cause the internal lubricating oil to evaporate. When the internal lubricating oil is lost, it may cause direct contact and friction between the bracket 13 and the valve stem nut 15, resulting in wear. By setting the grease nipples 22, lubricating oil can be injected into the interior, and lubricating oil can be injected regularly to reduce the wear of the equipment and increase its service life. At the same time, an intelligent oil change device can be set outside the grease nipples 22 to add lubricating oil regularly by recording the equipment usage time.

[0040] Specifically, a packing gland 21 is fixedly installed on the inner wall of the bracket 13. The bottom of the packing gland 21 is fixedly connected with oil seal packing 19, and there are two groups of oil seal packing 19. The bottom of each group of oil seal packing 19 is fixedly connected with a packing gasket 18.

[0041] In this embodiment, the setting of the packing gland 21 and the oil seal packing 19 can prevent the lubricating oil from leaking into the interior of the valve cover 10. If the lubricating oil enters the interior of the equipment, it may affect the purity of the fluid or cause damage to the equipment.

[0042] Specifically, screw holes are provided on the outer wall of the valve cover 10. The inner wall of the screw holes is threadedly connected with socket head cap screws 20, and there are multiple groups of socket head cap screws 20. The outer wall of each group of socket head cap screws 20 penetrates through the bracket 13.

[0043] In this embodiment, the valve cover 10 and the bracket 13 are fixedly installed by the socket head cap screws 20, so that the valve cover 10 and the bracket 13 fit more closely, improving the sealing performance between the valve cover 10 and the bracket 13 and preventing loosening caused by equipment vibration.

[0044] Specifically, bolt holes are provided at the bottom of the intelligent electric actuator 24. The outer wall of the bolt holes is threadedly connected with socket head cap bolts 16, and there are multiple groups of socket head cap bolts 16. Each group of socket head cap bolts 16 penetrates through the bracket 13.

[0045] In this embodiment, the intelligent electric actuator 24 and the bracket 13 are fixedly installed by the hexagon socket head cap screw 16, which increases the sealing performance between the intelligent electric actuator 24 and the bracket 13 and prevents the internal lubricating oil from leaking into the intelligent electric actuator 24 to prevent damage to the intelligent electric actuator 24.

[0046] During use,

[0047] First, the intelligent electric actuator 24 is started to drive the valve stem nut 15 to rotate. When the valve stem nut 15 rotates, it drives the valve stem body 8 to move through the thread. When the valve stem body 8 moves, it pushes the valve seat bushing 6 to move, and during the movement of the valve seat bushing 6, the fluid holes on the valve seat body 3 are blocked to adjust the flow rate to ensure that the flow rate remains unchanged. During use, the valve seat bushing 6 does not directly contact the fluid, avoiding the deterioration of the sealing performance caused by fluid erosion and wear. Moreover, by adjusting the flow rate by blocking the number of fluid holes by the valve seat bushing 6, the adjustment accuracy can be increased, and the fluid entering through the fluid holes can disperse the pressure of the fluid, thereby avoiding the generation of turbulence.

[0048] Then, when the internal pressure is too high, the pressure relief valve 5 can also be used to relieve the pressure to prevent the reduction of the service life of the equipment due to excessive pressure.

[0049] Finally, when the flow rate needs to be increased, the intelligent electric actuator 24 drives the valve stem nut 15 to rotate in the reverse direction. At this time, the valve stem body 8 moves upward and pulls the positioning bushing 7. Since the positioning bushing 7 is fixedly connected to the valve seat bushing 6, the positioning bushing 7 drives the valve seat bushing 6 to move upward, thereby reducing the blockage of the fluid holes and increasing the flow rate.
