Description

[0003] In a steam pipeline system, when steam cools, condensate is generated. This water usually contains dissolved minerals and chemicals and is called condensate; these dissolved substances will deposit on the pipeline wall and other surfaces in solid form after steam condensation, forming scale; and in the pipeline, the fluid is not static but flows at a certain speed and dynamic pressure. When the fluid flows in the pipeline, it will exert a certain force and shear force on the scale on the inner wall of the pipeline. This may cause some of the scale to be peeled off, especially those that are not completely fixed or poorly adhered; it is easy to move or fall off under the impact of the fluid; these scale fragments or particles will be carried by the fluid to the contact part between the float and the valve plate, causing scale to accumulate at the contact part between the float and the valve plate; thus preventing the float from rising or falling freely, thereby affecting the normal operation of the trap.

[0030] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0031] As shown in Figures 1 to 8As shown, a marine lever valve body structure of the present invention includes the following embodiments:

[0032] A marine lever valve body structure, comprising:

[0033] A valve body 1, wherein the surface of the valve body 1 is provided with a water inlet 11, a water outlet 12 and a mounting port 13 in sequence from top to bottom; a valve cover 131 is fixedly installed near the mounting port 13 of the valve body 1; a valve plate 2 is arranged inside the mounting port 13; a valve stem 14 is arranged between the valve plate 2 and the valve cover 131; one end of the valve stem 14 is threadedly connected to the valve cover 131, and the other end is connected to the valve plate 2; a floating ball 15 is arranged inside the valve body 1;

[0034] The mounting plate 16 is fixedly mounted in the water outlet 12; a lever 161 is arranged between the float 15 and the mounting plate 16; the lever 161 is rotatably connected to the mounting plate 16; a through groove 162 communicating with the water outlet 12 is provided on the surface of the mounting plate 16; a sealing plate 163 is slidably and sealably connected in the through groove 162; the sealing plate 163 is fixedly connected to the end of the lever 161 away from the float 15;

[0035] The storage groove 21 is provided on a side of the valve plate 2 close to the valve body 1; a storage cavity 211 connected to the storage groove 21 is provided in the valve plate 2; a push plate 212 is rotatably connected in the storage cavity 211; a driving unit is provided in the valve body 1; the driving unit is used to drive the push plate 212 to rotate.

[0036] In this embodiment, the upper end of the valve plate 2 is rotatably connected to a shovel plate 17; the shovel plate 17 is fixedly connected to the push plate 212; a blocking rod 171 is provided above the shovel plate 17 and is slidably connected to it; the blocking rod 171 is fixedly connected to the valve body 1; and a discharge port 22 connected to the storage chamber 211 is provided at the lower end of the valve plate 2.

[0037] In this embodiment, the driving unit includes a bevel gear ring 231; the bevel gear ring 231 is rotatably connected in the water inlet 11; a vane 23 is fixedly installed on the inner wall of the bevel gear ring 231; a cavity 24 is opened in the valve body 1; a bevel gear shaft 241 is rotatably connected in the cavity 24; the bevel gear shaft 241 and the push plate 212 are connected through a gear set.

[0038] In this embodiment, an elastic shell 232 is fixedly connected to the surface of the blade 23; the elastic shell 232 is made of PTFE material.

[0039] In this embodiment, the gear set includes a transmission gear 242 and a connecting gear 243; the transmission gear 242 meshes with the bevel gear shaft 241; a groove 244 is formed at one end of the transmission gear 242 away from the bevel gear shaft 241; the connecting gear 243 is slidably connected in the groove 244; the connecting gear 243 is fixedly connected to the bottom of the groove 244 through a connecting spring 245; an bevel gear ring 25 fixedly connected to the push plate 212 is rotatably connected in the storage cavity 211; a slot 251 facing the connecting gear 243 is formed on the side wall of the valve plate 2; an electromagnetic sheet 246 is embedded in the bottom of the groove 244; a solenoid valve 221 is installed in the discharge port 22;

[0040] During operation, in the steam pipe system, when the steam cools, condensate will be generated. This water usually contains dissolved minerals and chemicals and is called condensate; these dissolved substances will deposit on the pipe wall and other surfaces in solid form after the steam condenses, forming scale; in the pipe, the fluid is not static, but flows at a certain speed and dynamic pressure. When the fluid flows in the pipe, it will exert a certain force and shear force on the scale on the inner wall of the pipe. This may cause part of the scale to peel off, especially those that are not fully fixed or poorly attached; it is easy to move or fall off under the impact of the fluid; these scale fragments or particles will be carried by the fluid to the contact part between the float 15 and the valve plate 2, causing the scale to accumulate at the contact part between the float 15 and the valve plate 2; thus making the float 15 unable to rise or fall freely, thereby affecting the normal operation of the steam trap; especially for cruisers and aircraft carriers, because they carry large shipboard engines or nuclear power systems, the operation of these systems will generate a large amount of heat and condensate; to ensure the timely and effective discharge of a large amount of condensate and maintain the stable operation and safety of the ship system; so it is necessary to install a large and efficient lever float type steam trap to discharge the condensate; and the generation of a large amount of condensate will naturally lead to the continuous generation of a large amount of scale;

[0041] In response to this, the present invention enables the condensate to drive the vane 23 to rotate when flowing out of the water outlet 12 by setting the cooperation between the vane 23 and the push plate 212, so that the vane 23 can drive the gear set to drive the push plate 212 to rotate, and the push plate 212 can push the scale falling into the storage tank 21 into the discharge port 22 through the storage cavity 211 during the rotation process and finally discharge it from the discharge port 22; thus avoiding the accumulation of scale at the contact part between the float 15 and the valve plate 2; ensuring that the float 15 can rise or fall freely, thereby ensuring the long-term use effect of the steam trap; improving the practicality of the present invention;

[0042] In the initial state, the discharge port 22 is connected to an external drainage pump through a connecting pipe; the solenoid valve 221 in the discharge port 22 is in a closed state; the water inlet 11 is connected to a condensate pipe; when it is necessary to discharge the condensate, control the condensate pipe to convey the condensate into the valve body 1 through the water inlet 11, so that the condensate accumulates in the valve body 1. As the condensate enters the valve body 1, at this time, the condensate will generate a buoyant force on the floating ball 15 in the valve body 1, causing the floating ball 15 to rise under the action of the buoyant force and push the sealing plate 163 to rotate away from the through groove 162 through the lever 161, so that the through groove 162 of the mounting plate 16 is opened, and the valve body 1 is communicated with the water outlet 12 through the through groove 162. At this time, the condensate flowing into the valve body 1 will flow out through the through groove 162 and the water outlet 12. Since the condensate is generated by the condensation of steam, when the condensate decreases, the steam will enter the valve body 1 through the water inlet 11, so that the condensate in the valve body 1 is discharged under the action of air pressure. At this time, the floating ball 15 in the valve body 1 is no longer affected by the buoyant force of the condensate. At this time, the floating ball 15 will descend under the action of gravity until the floating ball 15 is reset. At this time, the sealing plate 163 is reset and blocks the through groove 162, so that the valve body 1 is no longer communicated with the water inlet 11;

[0043] During the process of condensate discharge, the condensate will carry scale into the valve body 1, and the scale will fall into the storage tank 21 under its own gravity. In the initial state, the push plate 212 blocks in the storage tank 21, so the scale falling into the storage tank 21 is located on the lower end face of the push plate 212 at this time. Since when the condensate is discharged from the water outlet 12, the condensate will generate an impact force on the vane 23 in the water outlet 12, causing the vane 23 to drive the bevel gear ring 231 connected to it to rotate under the impact of the condensate, so that the bevel gear ring 231 can drive the bevel gear shaft 241 meshing with it to rotate during the rotation process. Since the bevel gear shaft 241 meshes with the transmission gear 242, the bevel gear shaft 241 can drive the transmission gear 242 to rotate, and the connecting gear 243 is slidably connected in the groove 244 of the transmission gear 242, so that the transmission gear 242 can drive the connecting gear 243 to rotate. Since in the initial state, the connecting gear 243 is located in the slot 251 and meshes with the bevel gear ring 25, during the process of the transmission gear 242 driving the connecting gear 243 to rotate, the connecting gear 243 can drive the bevel gear ring 25 meshing with it to rotate, so that the bevel gear ring 25 drives the push plate 212 to rotate, and the push plate 212 rotates in the storage cavity 211. The scale located on the upper end face of the push plate 212 is blocked by the wall of the storage tank 21, so that the scale falling on the upper end face of the push plate 212 will slide on the upper end face of the push plate 212 until the push plate 212 crosses the storage tank 21. At this time, the scale on the upper end face of the push plate 212 falls into the storage cavity 211 under its own gravity. As the push plate 212 continues to rotate, the push plate 212 located behind rotates to the storage tank 21 at this time, so that the push plate 212 pushes the scale falling into the storage cavity 211 to move in the direction of the discharge port 22. When the push plate 212 crosses the storage tank 21, the scale is located between the two push plates 212 at this time, so that the scale is in a relatively sealed environment. Since the liquid flow in the sealed environment tends to be more stable and orderly, the scale will sink faster at this time, so that the sinking scale can fall to the bottom of the storage cavity 211, and the push plate 212 that pushes the scale will move in the direction of the discharge port 22, so that the scale moving to the discharge port 22 will fall into the discharge port 22.

[0044] Therefore, through the setting of the two push plates 212 in the present invention, when the push plates 212 push the scale to the discharge port 22, the scale is located between the two push plates 212, so that a sealed environment is formed between the two push plates 212 and the wall of the storage cavity 211, making the flow of the condensate containing scale between the two push plates 212 and the storage cavity 211 tend to be more stable and orderly; thereby accelerating the sinking of the scale, avoiding the generation of vortices due to the non-flow of the condensate containing scale, preventing the sinking scale from being lifted due to the vortices when the condensate drives the scale to flow to the discharge port 22, and thus ensuring that the scale can be stably pushed into the discharge port 22.

[0045] By arranging an electromagnetic sheet 246 embedded in the groove 244, during the installation process of the valve plate 2, by controlling the energization of the electromagnetic sheet 246, the electromagnetic sheet 246 can generate a magnetic adsorption force on the connecting gear 243, causing the connecting gear 243 to be adsorbed by the electromagnetic sheet 246 and squeeze the connecting spring 245 into the groove 244. Then, the valve stem 14 is rotated, causing the valve stem 14 to drive the valve plate 2 to rotate into the installation port 13. At this time, the electromagnetic sheet 246 is controlled to be powered off, so that the connecting gear 243 extends out of the groove 244 under the pushing force of the restoring force of the connecting spring 245 and contacts the valve plate 2, making the connecting gear 243 in sliding contact with the valve stem 14 until the valve stem 14 drives the valve plate 2 to completely enter the installation port 13, and the slot 251 on the surface of the valve plate 2 rotates to the position of the groove 244 and aligns with the groove 244. At this time, the connecting gear 243 in the groove 244 enters the slot 251 under the pushing of the connecting spring 245, so that the connecting gear 243 entering the slot 251 meshes with the bevel gear ring 25; when the valve plate 2 needs to be removed, only the electromagnetic sheet 246 needs to be controlled to be energized to adsorb the connecting gear 243 into the groove 244, so that the valve plate 2 is no longer connected to the valve body 1 through the connecting gear 243. At this time, the user rotates the valve stem 14 to take out the valve plate 2 from the installation port 13. By arranging the connecting gear 243 to be slidably connected to the transmission gear 242, the present invention not only ensures the meshing of the connecting gear 243 with the bevel gear ring 25, but also facilitates the user to install and disassemble the valve plate 2, reduces the installation difficulty of the valve plate 2, and improves the practicability of the present invention; in addition, during the process of condensate discharge, when the scale in the discharge port 22 needs to be discharged due to excessive accumulation, the user needs to control the electromagnetic sheet 246 to be energized when the push plate 212 rotates to the storage tank 21 and blocks the storage tank 21, so that the electromagnetic sheet 246 adsorbs the connecting gear 243 into the groove 244, making the connecting gear 243 not mesh with the bevel gear ring 25. At this time, the push plate 212 stops rotating, and the solenoid valve 221 is controlled to be energized, so that the discharge port 22 is opened, and the scale in the external discharge port 22 is discharged through an external drainage pump; at this time, the storage tank 21 is blocked by the push plate 212, so that the condensate in the valve body 1 will not be discharged from the discharge port 22, thereby ensuring the internal sealing of the valve body 1;

[0046] By setting the scraping plate 17, during the rotation of the pushing plate 212, the pushing plate 212 can drive the scraping plate 17 to rotate synchronously, so that the scraping plate 17 can push the water scale falling on the upper surface of the valve plate 2 into the storage tank 21. This is because when the water scale accumulates in other parts of the hydrophobic valve body 1, they will also enter the moving path of the floating ball 15 along with the fluid flow. For example, when the condensate is about to be discharged, the condensate liquid level in the valve body 1 drops at this time, and the speed and flow force of the condensate will weaken. This causes the water scale accumulated in the gas part of the valve body 1 to start to loosen and slide below the floating ball 15, thus blocking the normal descent of the floating ball 15. Therefore, by setting the scraping plate 17, the scraping plate 17 can push the water scale accumulated in other parts of the hydrophobic valve body 1 into the storage tank 21 during rotation, thereby reducing the accumulation of water scale in the valve body 1 and preventing the accumulated water scale from sliding below the floating ball 15 when the condensate is discharged, and further ensuring the normal lifting and lowering of the floating ball 15, and then improving the practical application effect of the present invention. By setting the elastic shell 232 on the surface of the vane 23, the elastic shell 232 made of PTFE material has the advantages of good elasticity and low surface smooth friction coefficient. When the condensate drives the water scale inside it to impact on the vane 23, the elastic shell 232 on the vane 23 can protect the vane 23, reduce the impact wear caused by the vane 23, improve the service life of the vane 23, and the smooth elastic shell 232 can prevent water scale particles from adhering to the surface of the vane 23, ensuring that the vane 23 can rotate normally and stably, improving the effect of the vane 23 driving the pushing plate 212 to rotate, and enhancing the practicability of the present invention.

[0047] Embodiment 2, the difference compared with Embodiment 1 is that:

[0048] The driving unit includes a plug rod 3; one end of the valve rod 14 far from the cover plate is rotatably connected in the storage cavity 211; a rotating cylinder 31 fixedly connected with the pushing plate 212 is sleeved on the surface of the valve rod 14; a connecting groove 311 is formed on the surface of the valve rod 14; the plug rod 3 is slidably connected in the connecting groove 311; the plug rod 3 is connected with the bottom of the connecting groove 311 through a support spring 312; a clamping groove 313 opposite to the connecting groove 311 is formed on the inner wall of the rotating cylinder 31.

[0049] In this embodiment, a handle 32 is fixedly connected to one end of the valve rod 14 far from the valve plate 2; an arc groove 321 is formed on the inner wall of the handle 32; an arc plate 322 is slidably and sealingly connected in the arc groove 321; an air passage 33 is formed inside the valve rod 14; one end of the air passage 33 is communicated with the arc groove 321; the other end is communicated with the connecting groove 311.

[0050] In this embodiment, a protrusion 34 is fixedly connected to the surface of the valve stem 14; a spiral groove 35 and an annular groove 351 are formed in the inner wall of the valve cover 131; the annular groove 351 communicates with the spiral groove 35; the protrusion 34 is slidably connected in the spiral groove 35; a sealing plug 36 is slidably and sealingly connected in the discharge port 22;

[0051] During operation, for civilian ships such as small passenger ships and fishing boats, they are usually equipped with diesel engines or electric systems with relatively low power, and the amount of condensate generated is relatively small. Therefore, only a small lever float type steam trap is needed to discharge the condensate, and the impact force generated by the discharge of a small amount of condensate on the vane 23 is relatively small. Therefore, a small lever float type steam trap is not suitable for driving the vane 23. In the initial state, the user rotates the grip 32 so that the grip 32 can drive the valve stem 14 to rotate. Since the valve stem 14 is connected to the spiral groove 35 of the valve cover 131 through the protrusion 34 on the surface in a spiral drive connection, during the rotation of the valve stem 14, the valve stem 14 will move along the spiral groove 35 towards the valve body 1 through the protrusion 34 on the surface. At this time, the valve stem 14 pushes the valve plate 2 into the installation port 13. When the protrusion 34 on the surface of the valve stem 14 enters the annular groove 351 communicating with the spiral groove 35, the valve plate 2 completely enters the installation port 13. When the user needs to clean the water scale, the user only needs to manually hold the grip 32, and thus tightly hold the arc-shaped plate 322 during the process of holding the grip 32, so that the arc-shaped plate 322 squeezes the hydraulic oil in the arc-shaped groove 321 into the air passage 33 and enters the connecting groove 311 under the grip of the user's palm. The insertion rod 3 in the connecting groove 311 stretches the support spring 312 and extends out of the connecting groove 311 under the push of the hydraulic oil. At this time, the connecting rod contacts the inner wall of the rotating cylinder 31. As the user rotates the grip 32, the grip 32 can drive the valve stem 14 to rotate relative to the rotating cylinder 31, and the protrusion 34 on the surface of the valve stem 14 rotates in the annular groove 351. Until the connecting groove 311 rotates to be aligned with the card slot 313, the insertion rod 3 pushed by the hydraulic oil stretches the support spring 312 and enters the card slot 313. At this time, the user drives the rotating cylinder 31 to rotate by rotating the valve stem 14, so that the rotating cylinder 31 can drive the pushing plate 212 connected thereto to rotate. When the pushing plate 212 rotates and passes over the storage tank 21, the water scale on the pushing plate 212 can enter the storage cavity 211 under the block of the tank wall of the storage tank 21, and the pushing plate 212 located behind pushes the water scale entering the storage cavity 211 into the discharge port 22. When the rotating pushing plate 212 rotates to the lower part of the storage tank 21 again and blocks the storage tank 21. When the user needs to clean the water scale in the discharge port 22, the user only needs to remove the sealing plug 36 in the discharge port 22 to clean the water scale in the discharge port 22, and there is no need to install a solenoid valve 221 or cooperate with a water pump, which not only reduces the production cost of the present invention, but also reduces the use difficulty of the present invention, so as to facilitate the consumption and use of civilian ships such as small passenger ships and fishing boats.
