Description

Technical Field

[0001] This invention belongs to the field of steam trap technology, and specifically relates to a steam trap regulating valve. Background Technology

[0002] Steam, as an important secondary energy source, is indispensable in many industrial fields. Steam traps are important self-operated control valves that ensure the normal operation of steam systems and save energy.

[0003] The inside of the inverted bucket-type steam trap is an inverted bucket that serves as a liquid level sensor. The bucket opening faces downwards, and the lever connected to the inverted bucket drives the valve core to open and close the valve. A drain plug and filter screen are installed at the bottom.

[0004] When the drain plug and filter screen are cleaned regularly, the valve body is in the open position, the steam system needs to be stopped, and the filter screen needs to be removed, which is inconvenient. Summary of the Invention

[0005] The purpose of this invention is to provide a hydrophobic regulating valve to solve the problem that when the drain plug and filter screen are cleaned regularly, the valve body is in the open state, the steam system needs to be stopped, and the filter screen needs to be removed, which is inconvenient for disassembly and assembly.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0007] A hydrophobic regulating valve includes a valve body, a valve cover with a water outlet, a water outlet connector fixedly connected to the valve body and communicating with the water outlet, a water inlet pipe at the bottom of the valve body, a rod rotatably mounted at the bottom of the valve cover, a closing plug fixedly connected to the rod below the water outlet, a barrel rotatably mounted at the free end of the rod, a water inlet connector fixedly connected to the valve body, a filter pipe disposed below the valve body and communicating with the water inlet connector and the water inlet pipe, two filter units for filtering liquids slidably mounted inside the filter pipe, the two filter units being located on opposite sides of the water inlet pipe, a moving unit installed inside the filter pipe, the moving unit controlling the two filter units to alternately open and close, a cleaning unit installed on the valve body for cleaning the closed filter units, and a switching pipe connected to the filter pipe, after the filter units switch on and off, liquid flows into the water inlet pipe through the switching pipe.

[0008] Further specifying, the movable unit includes a mounting base fixedly connected to one end of the filter pipe. A threaded rod is screwed onto the mounting base, and a movable rod is fixedly connected to the threaded rod inside the filter pipe. The filter unit is mounted on the movable rod. This structural design allows the filter unit to be moved by rotating the threaded rod, thereby changing the state of the filter unit.

[0009] Further specified, the filter pipe has a first sliding groove and a second sliding groove axially formed inside, the length of the second sliding groove being smaller than the length of the first sliding groove. The filter unit includes a first closing plate, a filter plate, and a second closing plate. The first closing plate is rotatably connected to a moving rod and slidably installed in the first sliding groove. The moving rod has two annular grooves. The filter plate is movably installed in the annular groove and slidably connected to the second sliding groove. The second closing plate is fixedly connected to the filter pipe and slidably connected to the moving rod. The second closing plate is located between the filter plate and the inlet pipe. The ends of the first and second closing plates near the filter plate have cavities. Both the first and second closing plates have through grooves. The filter plate has filter holes in the cavity. When the filter unit is closed, both the first and second closing plates are close to the filter plate. This structural design, through the mutual cooperation of the first closing plate, the filter plate, and the second closing plate, rotates the threaded rod, causing the threaded rod to move the first closing plate toward the second closing plate, sealing the filter holes in the cavity. After one side of the filter unit is closed, the other side of the filter unit is opened, making it convenient for the operator to use.

[0010] Further specified, the first closing plate has a first through hole at the bottom of the cavity, the second closing plate has an upper sliding groove at its top, the filter plate is fixedly connected to an upper sliding plate within the upper sliding groove, the upper sliding plate has a second through hole, the second closing plate has a lower sliding groove at its bottom, the filter plate is fixedly connected to a lower sliding plate within the lower sliding groove, the valve body has an inlet hole above the upper sliding plate, and the valve body has an outlet hole below the lower sliding plate. When the cleaning unit is closed, the outlet hole communicates with the first through hole, and the inlet hole communicates with the second through hole. With this structural design, through the cooperation of the upper and lower sliding plates, when the filter unit is closed, water is introduced into the inlet hole, reversing the flow of water through the filter holes, and then discharged through the outlet hole. The steam system does not need to operate during cleaning.

[0011] Further specifying, the valve body has an annular groove at its bottom, and both liquid inlets are connected to the annular groove. The cleaning unit includes a cleaning pipe, and the water outlet connector has a water storage chamber at its bottom. The cleaning pipe is connected to both the water storage chamber and the liquid inlets. This structural design connects the two liquid inlets through the annular groove, and the cleaning pipe guides some of the discharged condensate into the liquid inlets for automatic cleaning of the filter unit.

[0012] Furthermore, a switching valve is provided on the outer side of the valve body. This switching valve is connected to two liquid outlet pipes and controls the opening and closing of the two liquid outlets. This structural design, by controlling the opening and closing of the liquid outlets through the switching valve, allows the valve to be closed after cleaning, thus saving condensate.

[0013] Furthermore, the valve cover is bolted to the valve body, and a sealing ring is provided between the valve cover and the outlet connector. This structural design, with its detachable valve body and valve cover, and the sealing ring used to ensure the seal between the outlet connector and the valve cover, facilitates subsequent disassembly and installation.

[0014] Furthermore, the valve cover is fixedly connected to a retaining ring inside the water outlet, and a tension spring is fixedly connected below the retaining ring. An elastic ring is fixedly connected to the free end of the tension spring. This structural design, by incorporating a tension spring and an elastic ring in the water outlet, reduces direct impact on the water outlet when the valve is closed, thereby improving its service life.

[0015] The invention employing the above technical solution has the following advantages:

[0016] 1. Through the cooperation of the cleaning unit, the moving unit and two filter units, filtration is performed using a filter unit on one side. The closing state of the filter unit is changed periodically by the moving unit, and the steam and liquid change their flow direction, flowing into the water inlet pipe through the filter unit on the other side. At the same time, the cleaning unit is used to clean the closed filter unit. The filter screen does not need to be disassembled during cleaning, and the steam system does not need to be stopped.

[0017] 2. Through the cooperation of the first closing plate, the filter plate and the second closing plate, the threaded rod is rotated, which causes the threaded rod to drive the first closing plate to move toward the second closing plate. The restriction of the first sliding groove and the second sliding groove ensures that the first closing plate and the filter plate can only move in a straight line, ensuring that the filter holes and the cavity are aligned. After the filter unit on one side is closed, the filter unit on the other side is opened, which is convenient for the operator to use.

[0018] 3. Through the cooperation of the upper and lower sliding plates, when the filter unit is closed, water is introduced into the inlet hole to reverse the filter hole and then discharged through the outlet hole. The steam system does not need to work during cleaning. Attached Figure Description

[0033] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art.

[0034] like Figures 1 to 7As shown, a hydrophobic regulating valve includes a valve body 1, a valve cover 2 mounted on the valve body 1, a water outlet 21 on the valve cover 2, a water outlet connector 11 fixedly connected to the valve body 1, the water outlet connector 11 communicating with the water outlet 21, a water inlet pipe 12 provided at the bottom of the valve body 1, a rod 13 rotatably mounted at the bottom of the valve cover 2, a closing plug 14 fixedly connected to the rod 13 below the water outlet 21, a barrel 15 rotatably mounted at the free end of the rod 13, a water inlet connector 16 fixedly connected to the valve body 1, and a filter pipe 17 provided below the valve body 1. The filter pipe 17 is connected to the inlet connector 16 and the inlet pipe 12 respectively. Two filter units 3 for filtering liquid are slidably installed in the filter pipe 17. The two filter units 3 are located on both sides of the inlet pipe 12 respectively. A moving unit 4 is installed in the filter pipe 17. The moving unit 4 controls the two filter units 3 to open and close alternately. A cleaning unit 5 is installed on the valve body 1. The cleaning unit 5 is used to clean the closed filter unit 3. A switching pipe 18 is connected to the filter pipe 17. After the filter unit 3 is switched to open and close, the liquid flows into the inlet pipe 12 through the switching pipe 18.

[0035] like Figure 2 As shown, the movable unit 4 includes a mounting base 41, which is fixedly connected to one end of the filter pipe 17. A threaded rod 42 is screwed onto the mounting base 41, and a movable rod 43 is fixedly connected to the threaded rod 42 inside the filter pipe 17. The filter unit 3 is mounted on the movable rod 43. By rotating the threaded rod 42, the filter unit 3 can be moved, thereby changing the state of the filter unit 3.

[0036] like Figures 2-4As shown, the filter pipe 17 has a first sliding groove 171 and a second sliding groove 172 axially formed inside. The length of the second sliding groove 172 is smaller than the length of the first sliding groove 171. The filter unit 3 includes a first closing plate 31, a filter plate 32, and a second closing plate 33. The first closing plate 31 is rotatably connected to the moving rod 43 and slidably installed in the first sliding groove 171. The moving rod 43 has two annular grooves. The filter plate 32 is movably installed in the annular grooves and slidably connected to the second sliding groove 172. The second closing plate 33 is fixedly connected to the filter pipe 17 and slidably connected to the moving rod 43. The second closing plate 33 is located between the filter plate 32 and the water inlet pipe 12. The first closing plate 31 and the second closing plate 33 have cavities 34 at the ends near the filter plate 32. Both the first closing plate 31 and the second closing plate 33 have through grooves 35. The filter plate 32 has filter holes 36 in the cavity 34. When the filter unit 3 is closed, both the first closing plate 31 and the second closing plate 33 are close to the filter plate 32. Through the cooperation of the first closing plate 31, the filter plate 32 and the second closing plate 33, the threaded rod 42 is rotated, causing the threaded rod 42 to drive the first closing plate 31 to move toward the second closing plate 33. The filter hole 36 is sealed in the cavity 34. After the filter unit 3 on one side is closed, the filter unit 3 on the other side is opened, which is convenient for the operator to use.

[0037] like Figure 2 and Figure 3 As shown, the first closing plate 31 has a first through hole 341 at the bottom of the cavity 34, the second closing plate 33 has an upper sliding groove at its top, the filter plate 32 has an upper sliding plate 37 fixedly connected in the upper sliding groove, the upper sliding plate 37 has a second through hole 371, the second closing plate 33 has a lower sliding groove at its bottom, the filter plate 32 has a lower sliding plate 38 fixedly connected in the lower sliding groove, the valve body 1 has an inlet hole 51 above the upper sliding plate 37, and an outlet hole 52 below the lower sliding plate 38. When the cleaning unit 5 is closed, the outlet hole 52 communicates with the first through hole 341, and the inlet hole 51 communicates with the second through hole 371. Through the cooperation of the upper sliding plate 37 and the lower sliding plate 38, when the filter unit 3 is closed, water is introduced into the inlet hole 51 to reverse the flow of the filter holes 36, and then discharged through the outlet hole 52. The steam system does not need to work during cleaning.

[0038] The valve body 1 has an annular groove at its bottom, and both inlet holes 51 are connected to the annular groove. The cleaning unit 5 includes a cleaning pipe 53, and the water outlet connector 11 has a water storage chamber 54 at its bottom. The cleaning pipe 53 is connected to both the water storage chamber 54 and the inlet holes 51. The two inlet holes 51 are connected through the annular groove, and the cleaning pipe 53 guides some of the discharged condensate into the inlet holes 51 to automatically clean the filter unit 3.

[0039] A switch valve 55 is installed on the outside of the valve body 1. The switch valve 55 is connected to two liquid outlet holes 52 and controls the opening and closing of the two liquid outlet holes 52. By controlling the opening and closing of the liquid outlet holes 52 through the switch valve 55, the switch valve 55 is closed after cleaning to save condensate.

[0040] The valve cover 2 is bolted to the valve body 1, and a sealing ring 22 is provided between the valve cover 2 and the outlet connector 11. By providing a detachable valve body 1 and valve cover 2, the sealing ring 22 is used to ensure the sealing between the outlet connector 11 and the valve cover 2, which facilitates subsequent disassembly and installation.

[0041] A retaining ring 23 is fixedly connected to the valve cover 2 inside the water outlet 21. A tension spring 24 is fixedly connected below the retaining ring 23, and an elastic ring 25 is fixedly connected to the free end of the tension spring 24. By setting the tension spring 24 and the elastic ring 25 in the water outlet 21, the direct impact on the water outlet 21 is reduced when the closing plug 14 is closed, thereby improving its service life.

[0042] The usage method and principle of this embodiment are as follows:

[0043] When using the left-side filter unit 3, steam and liquid enter the filter pipe 17 through the water inlet connector 16, pass through the through groove 35 on the first closed plate 31, are filtered through the filter hole 36, and finally pass through the through groove 35 on the second closed plate 33 to complete the filtration. When using the right-side filter unit 3, steam and liquid enter the filter pipe 17 through the water inlet connector 16, flow back to the filter pipe 17 through the switching pipe 18, and are filtered again.

[0044] The filtered steam and liquid enter the valve body 1 through the water inlet pipe 12. The steam condenses into condensate. As the gas and liquid in the tank 15 change, the tank 15 rises or falls continuously. When the tank 15 rises, the closing plug 14 strikes the elastic ring 25. The tension spring 24 reduces the impact force, and the closing plug 14 and the elastic ring 25 close. When the tank 15 falls, the closing plug 14 opens, and the condensate is discharged to the water outlet 11 and the water storage chamber 54. After the condensate is discharged, the tank 15 falls again.

[0045] When the filter unit 3 needs to be cleaned, rotate the threaded rod 42. For the open filter unit 3, the threaded rod 42 drives the first closing plate 31 and the filter plate 32 to move toward the second closing plate 33. Due to the restriction of the first sliding groove 171 and the second sliding groove 172, the first closing plate 31 and the filter plate 32 can only move in a straight line until the filter plate 32 contacts the first closing plate 31 and the second closing plate 33 respectively. The filter hole 36 is sealed in the cavity 34. At this time, the liquid outlet hole 52 is connected to the first through hole 341, and the liquid inlet hole 51 is connected to the second through hole 371.

[0046] Rotating the threaded rod 42 causes the first closing plate 31 and the filter plate 32 to move away from the second closing plate 33 and return to the open position for the closed filter unit 3.

[0047] When there is a requirement for condensate recovery, the switch valve 55 is connected to the sewage collection tank. The switch valve 55 is opened at regular intervals, and the condensate in the water storage chamber 54 enters the cavity 34 through the cleaning pipe 53 to perform reverse cleaning of the filter plate. The cleaned liquid flows into the sewage collection tank.

[0048] When there is no requirement for condensate recovery, the switch valve 55 is connected to the drain pipe and is in the normally open state, allowing condensate to continuously clean the drain.

[0049] The foregoing has provided a detailed description of a hydrophobic regulating valve provided by the present invention. The specific embodiments described are merely for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
