Description

Technical Field

[0001] The invention relates to the technical field of marine valves, in particular to a valve body structure of a marine lever valve. Background Art

[0002] Marine valves are valves specially used in ship systems. These valves need to have specific functions and performances to adapt to the marine environment, long-term operation, high pressure, high temperature or other special conditions. Since ships generate a large amount of steam and condensate during operation, in order to maintain the normal operation and safety of the system, these condensate needs to be discharged in time. The lever float steam trap automatically detects and discharges condensate in the system to prevent water accumulation from causing pipeline corrosion or abnormal system operation. Its working principle is based on the buoyancy and gravity of the float. Its main function is to automatically discharge condensate or other unnecessary liquids formed in the steam pipeline system to keep the pipeline dry and at normal working pressure. This valve is usually used in boilers, heating systems and other equipment that requires drainage. In the steam pipe system, condensate is produced when steam cools. This water usually contains dissolved minerals and chemicals, which is called condensate. These dissolved substances will be deposited in solid form on the pipe wall and other surfaces 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 the scale to be partially peeled off, especially those that are not completely fixed or not firmly attached; they are 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 area between the float and the valve plate, causing the scale to accumulate at the contact area between the float and the valve plate; thus, the float cannot rise or fall freely, thus affecting the normal operation of the steam trap; In view of this, in order to overcome the above technical problems, the present invention proposes a valve body structure of a marine lever valve, which solves the above technical problems.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0017] like Figures 1 to 8 As shown, a marine lever valve body structure of the present invention includes the following embodiments: A marine lever valve body structure, comprising: 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; 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; 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.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] In this embodiment, the gear set includes a transmission gear 242 and a connecting gear 243; the transmission gear 242 is meshed with the bevel gear shaft 241; a groove 244 is provided 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 by a connecting spring 245; a 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 provided on the side wall of the valve plate 2; an electromagnetic sheet 246 is inlaid at the bottom of the groove 244; an electromagnetic valve 221 is installed in the discharge port 22; During operation, in the steam pipe system, condensate is produced when the steam cools. This water usually contains dissolved minerals and chemicals, which is called condensate. These dissolved substances will be deposited 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 the scale to be partially peeled off, especially those that are not completely fixed or not firmly attached; they are 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, so that the scale accumulates at the contact part between the float 15 and the valve plate 2; so that the float 15 cannot rise or fall freely, thus affecting the normal operation of the steam trap; especially cruisers and aircraft carriers, because they are equipped with large shipborne engines or nuclear power systems, the operation of these systems will generate a lot of heat and condensate; in order to ensure the timely and effective discharge of a large amount of condensate and maintain the stable operation and safety of the ship system; therefore, it is necessary to install a large and efficient lever float 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; In this regard, the present invention sets the cooperation between the blade 23 and the push plate 212, so that when the condensed water flows out from the water outlet 12, the condensed water can push the blade 23 to rotate, so that the blade 23 can drive the gear set to drive the push plate 212 to rotate, so that the push plate 212 can push the scale that falls 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; thereby 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 effect of long-term use of the steam trap; so that the practicality of the present invention is improved; In the initial state, the discharge port 22 is connected to the external drainage pump through the connecting pipe; the solenoid valve 221 in the discharge port 22 is in the closed state; the water inlet 11 is connected to the condensate pipe; when it is necessary to discharge the condensate, the condensate pipe is controlled to transport the condensate into the valve body 1 through the water inlet 11, so that the condensate accumulates in the valve body 1 and enters the valve body 1 as the condensate enters the valve body 1; at this time, the condensate will generate buoyancy on the float 15 in the valve body 1, so that the float 15 rises under the action of the buoyancy and pushes 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 closed. 2 is opened, so that the valve body 1 is connected with the water outlet 12 through the through groove 162. At this time, the condensed water flowing into the valve body 1 will flow out through the through groove 162 and the water outlet 12. Since the condensed water is generated by the condensation of steam, when the condensed water decreases, the steam will enter the valve body 1 through the water inlet 11, so that the condensed water in the valve body 1 is discharged under the action of air pressure. At this time, the float 15 in the valve body 1 is no longer affected by the buoyancy of the condensed water. At this time, the float 15 will drop under the action of gravity until the float 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 connected with the water inlet 11. During the condensed water discharge process, the condensed water will carry scale into the valve body 1, so that the scale will fall into the storage tank 21 under its own gravity. In the initial state, the push plate 212 is blocked in the storage tank 21, so the scale that falls into the storage tank 21 is located at the lower end surface of the push plate 212. When the condensed water is discharged from the water outlet 12, the condensed water will generate an impact force on the blade 23 in the water outlet 12, so that the blade 23 will drive the bevel gear ring 231 connected to it to rotate under the impact of the condensed water, so that the bevel gear ring 231 can drive the bevel gear ring 231 connected to it during the rotation process. The meshed bevel gear shaft 241 rotates; since the bevel gear shaft 241 is meshed 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 meshed with the bevel gear ring 25, so that when the transmission gear 242 drives the connecting gear 243 to rotate, the connecting gear 243 can drive the meshed bevel gear ring 25 The bevel gear ring 25 drives the push plate 212 to rotate, so that the push plate 212 rotates in the storage chamber 211, and the scale on the upper end surface of the push plate 212 is blocked by the groove wall of the storage groove 21, so that the scale falling on the upper end surface of the push plate 212 will slide on the upper end surface of the push plate 212 until the push plate 212 passes over the storage groove 21. At this time, the scale on the upper end surface of the push plate 212 falls into the storage chamber 211 under the action of its own gravity. As the push plate 212 continues to rotate, the push plate 212 at the rear rotates to the storage groove 21, so that the push plate 212 The moving plate 212 pushes the scale that falls into the storage chamber 211 to move toward the discharge port 22. When the pushing plate 212 passes over the storage tank 21, the scale is located between the two pushing plates 212, so that the scale is located 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 sunken scale can fall to the bottom of the storage chamber 211, and push the pushing plate 212 to move the scale toward the discharge port 22, so that the scale moved to the discharge port 22 will fall into the discharge port 22. In this regard, the present invention provides two push plates 212. 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 cavity wall of the storage chamber 211, so that the condensed water containing scale tends to flow more stably and orderly between the two push plates 212 and the storage chamber 211; thereby accelerating the sinking of the scale, preventing the condensed water containing scale from generating vortices due to the lack of flow, and preventing the condensed water from driving the scale to flow to the discharge port 22. The sunken scale is lifted up due to the vortex, thereby ensuring that the scale can be stably pushed into the discharge port 22; The electromagnetic sheet 246 is embedded in the groove 244 so that during the installation of the valve plate 2, the electromagnetic sheet 246 can be energized to generate a magnetic attraction force on the connecting gear 243, so that the connecting gear 243 squeezes the connecting spring 245 into the groove 244 under the attraction of the electromagnetic sheet 246, and then the valve stem 14 is rotated so that the valve stem 14 drives the valve plate 2 to rotate into the installation port 13. At this time, the electromagnetic sheet 246 is de-energized so that the connecting gear 243 extends out of the groove 244 and is connected to the valve plate 2 under the push of the restoring force of the connecting spring 245. The valve plate 2 is in contact with the valve stem 14, so that the connecting gear 243 and the valve stem 14 are in sliding contact, 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 is rotated to the groove 244 and aligned with the groove 244. At this time, the connecting gear 243 in the groove 244 enters the slot 251 under the push of the connecting spring 245, so that the connecting gear 243 entering the slot 251 is meshed with the bevel gear ring 25; when the valve plate 2 needs to be removed, it is only necessary to control the electromagnetic sheet 246 to energize and adsorb the connecting gear 243 into the groove 244, so that the valve plate 2 is no longer The valve body 1 is connected to the connecting gear 243. At this time, the user removes the valve plate 2 from the installation port 13 by rotating the valve stem 14. The present invention sets a connecting gear 243 and a transmission gear 242 for sliding connection, thereby ensuring that the connecting gear 243 and the bevel gear ring 25 are meshed at the same time, and it is also convenient for the user to install and disassemble the valve plate 2, thereby reducing the installation difficulty of the valve plate 2, so that the practicality of the present invention is improved; in addition, when the condensed water is in the discharge state, when the scale in the discharge port 22 needs to be discharged due to excessive accumulation, the user needs to push the plate 212 to remove the scale. When the storage tank 21 is rotated to block the storage tank 21, the user controls the electromagnetic sheet 246 to be energized, so that the electromagnetic sheet 246 adsorbs the connecting gear 243 into the groove 244, so that the connecting gear 243 does not mesh with the bevel gear ring 25. At this time, the push plate 212 no longer rotates, and the electromagnetic valve 221 is controlled to be energized, so that the discharge port 22 is opened, so that the scale in the external discharge port 22 is discharged through the external drainage pump; at this time, the storage tank 21 is blocked by the push plate 212, so that the condensed water in the valve body 1 will not be discharged from the discharge port 22, thereby ensuring the sealing inside the valve body 1; By providing the shovel plate 17, during the rotation of the push plate 212, the push plate 212 can drive the shovel plate 17 to rotate synchronously, so that the shovel plate 17 pushes the scale that falls on the upper end surface of the valve plate 2 into the storage tank 21. This is because when scale accumulates in other parts of the steam trap body 1, they will also enter the movement path of the float 15 with the flow of fluid. For example, when the condensed water is about to be discharged, the condensed water level in the valve body 1 drops, and the speed and flow force of the condensed water will be weakened, which makes the scale accumulated in the gas part of the valve body 1 begin to loosen and slide to the bottom of the float 15, thereby preventing the float 15 from descending normally; therefore, by providing the shovel plate 17, the shovel plate 17 can push the scale accumulated in other parts of the steam trap body 1 into the storage tank 21 during the rotation process, thereby reducing the accumulation of scale in the valve body 1. This prevents the accumulated scale from sliding under the float 15 when the condensate is discharged, thereby ensuring the normal rise and fall of the float 15, thereby improving the practical application effect of the present invention; and by arranging an elastic shell 232 on the surface of the blade 23, the elastic shell 232 made of PTFE material has the advantages of good elasticity and a smooth surface and a low friction coefficient, so that when the condensate drives the scale inside it to hit the blade 23, the elastic shell 232 on the blade 23 can protect the blade 23, reduce the impact wear caused by the blade 23 on it, and increase the service life of the blade 23, and the smooth elastic shell 232 can prevent scale particles from adhering to the surface of the blade 23; it ensures that the blade 23 can rotate normally and stably, improves the effect of the blade 23 driving the push plate 212 to rotate, and improves the practicality of the present invention.

[0022] Embodiment 2 is different from Embodiment 1 in that: The driving unit includes an insertion rod 3; the end of the valve stem 14 away from the cover plate is rotatably connected in the storage cavity 211; the surface of the valve stem 14 is sleeved with a rotating cylinder 31 fixedly connected to the push plate 212; the surface of the valve stem 14 is provided with a connecting groove 311; the insertion rod 3 is slidably connected in the connecting groove 311; the insertion rod 3 is connected to the bottom of the connecting groove 311 through a supporting spring 312; the inner wall of the rotating cylinder 31 is provided with a card groove 313 opposite to the connecting groove 311.

[0023] In this embodiment, the end of the valve stem 14 away from the valve plate 2 is fixedly connected to a handle 32; the inner wall of the handle 32 is provided with an arc groove 321; the arc groove 321 is slidingly and sealingly connected with an arc plate 322; an air passage 33 is provided inside the valve stem 14; one end of the air passage 33 is connected to the arc groove 321; and the other end is connected to the connecting groove 311.

[0024] 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 on the inner wall of the valve cover 131; the annular groove 351 is connected to 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; When working, for civilian ships, such as small passenger ships and fishing boats; they are usually equipped with low-power diesel engines or electric systems, and the amount of condensed water generated is relatively small, so only a small lever float type steam trap is needed to discharge the condensed water, and the discharge of a small amount of condensed water has a small impact on the blade 23; therefore, the small lever float type steam trap is not suitable for driving the blade 23; in the initial state, the user rotates the handle 32 so that the handle 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, so during the rotation of the valve stem 14 , the valve stem 14 will move along the spiral groove 35 toward the valve body 1 through the protrusion 34 on the surface, and at this time the valve stem 14 pushes the valve plate 2 into the installation port 13; when the valve stem 14 drives the protrusion 34 on the surface to enter the annular groove 351 connected to the spiral groove 35, the valve plate 2 completely enters the installation port 13; when the user needs to clean the scale, he only needs to manually hold the handle 32, and in the process of holding the handle 32, hold the arc plate 322 tightly, so that the arc plate 322 squeezes the hydraulic oil in the arc groove 321 under the grip of the user's palm to enter the connecting groove 311 through the air channel 33, so that the plug rod 3 in the connecting groove 311 is stretched and supported by the hydraulic oil. The support spring 312 extends out of the connecting groove 311. At this time, the connecting rod contacts the inner wall of the rotating cylinder 31. As the user rotates the handle 32, the handle 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 face the clamping groove 313, the plug rod 3 pushed by the hydraulic oil stretches the support spring 312 to enter the clamping groove 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 push plate 212 connected thereto to rotate, so that when the push plate 212 rotates and passes over the storage tank 21, the scale on the push plate 212 can The scale in the discharge port 22 is cleaned by the sealing plug 36 in the discharge port 22 when the user needs to clean the scale in the discharge port 22. The user does not need to install the solenoid valve 221 or use it in conjunction with a water pump, which not only reduces the production cost of the present invention, but also reduces the difficulty of using the present invention, so as to facilitate the consumption and use of civilian ships such as small passenger ships and fishing boats.
