TECHNICAL FIELD

[0002] The electrically regulated hydraulic throttle valve changes the opening degree of the throttle port through the displacement of the valve core to achieve accurate flow control. However, the existing electrically regulated hydraulic throttle valve has the following problems in actual use:

[0003] The valve rod is prone to deformation under fluid impact: when the hydraulic oil impacts the valve rod at high speed (the actual instantaneous impact force is > 2000N), the high pressure impact force is easy to cause the valve rod to bend and deform, thereby causing sealing leakage and deterioration of the regulation accuracy;

[0021] Technical effects and advantages of the present application:

[0022] 1. This invention uses a regulating gas supply device to input a stable working current to generate corresponding gas and transmit it to the interior of a buffer monitoring mechanism. This gas is used to buffer the impact force generated during fluid transmission, further reducing the probability of valve stem deformation. At the same time, the buffer monitoring mechanism monitors the overall shape of the valve stem in real time to determine whether deformation has occurred. The regulating gas supply device generates compressed air at different temperatures and transmits it to the interior of the buffer monitoring mechanism to adjust the temperature of the fluid near the valve stem. This suppresses the contaminant adhesion effect induced by fluid temperature changes and reduces the probability of contaminants appearing on the valve stem and valve head surface.

[0023] 2. This invention generates compressed air by inputting a stable working current through a regulating gas supply device, and transmits it to the interior of the first annular conveying plate through a set of air outlets in a three-hole tube. The compressed air inside the first annular conveying plate is transmitted to the interior of the corresponding annular hollow plate through each set of first air grooves and each set of first hollow plates. The compressed air inside the annular hollow plate drives the rubber annular plate to be in an expanded state. The expanded rubber annular plate is attached to the outer surface of the rubber annular plate. When high-pressure fluid impacts the valve stem, each set of springs and the expanded rubber annular plate will provide a set of reverse buffering forces to the valve stem, thereby reducing the impact of external impact force on the valve stem as a whole and further reducing the probability of valve stem deformation.

DETAILED DESCRIPTION

[0032] The technical solutions in the application will be described clearly and completely below in combination with the drawings in the application, and in addition, the forms of each structure described in the following embodiments are only examples, and the electrically adjusted hydraulic throttle valve involved in the application is not limited to each structure described in the following embodiments. All other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the application.

[0033] Reference Figure 1 And Figure 2 The application provides an electrically adjusted hydraulic throttle valve, the electric throttle valve 1 is internally provided with a flow-through cabin, an oil inlet groove 104 is formed in the bottom of one side of the electric throttle valve 1, for conveying external fluid into the flow-through cabin, and an oil outlet groove is formed in the bottom of the other side of the electric throttle valve 1, for transmitting fluid in the flow-through cabin to the outside of the electric throttle valve 1.

[0034] An electric control adjusting assembly 101 is mounted on the upper surface of the electric throttle valve 1, a valve rod 102 is mounted at the transmission end of the electric control adjusting assembly 101, a valve head 103 is mounted at the valve rod 102 close to the oil outlet groove, the outer side surface of the valve head 103 is matched with the inner wall of the oil outlet groove, and a control system is integrated in the electric control adjusting assembly 101.

[0035] An adjusting type gas supply device 2 is mounted on the upper surface of the electric throttle valve 1 close to the electric control adjusting assembly 101, a buffer monitoring mechanism 3 is arranged on the outer surface of the valve head 103, for buffering the impact of fluid on the valve rod 102 and monitoring whether the valve rod 102 appears deformation phenomenon, and an automatic cleaning mechanism 4 is arranged on the side surface of the buffer monitoring mechanism 3 close to the valve head 103, for assisting in scraping the surface of part of the valve rod 102 and the outer surface of the valve head 103.

[0036] In the embodiments of the present application, the electric throttle valve 1 is installed with a flow meter on the outer side near the oil outlet groove position, which is used to collect the flow volume generated by the fluid in the oil outlet groove and transmit it to the control system. When the control system detects that the real-time flow volume collected by the flow meter is lower than the normal flow volume range, it is judged that the outer surface of the valve head 103 is contaminated, the control system generates a cleaning instruction, and controls the regulated gas supply device 2 to input a stable working current to generate compressed air and transmit it to the inside of the automatic cleaning mechanism 4 to perform scraping work on the outer surface of the valve head 103 and the surface of the valve stem 102 in some areas, so as to clean the contaminants attached to the outer surface of the valve head 103 and the surface of the valve stem 102 in some areas.

[0037] If the automatic cleaning mechanism 4 completes the cleaning of the contaminants, the flow meter again collects the flow volume generated by the fluid in the oil outlet groove and transmits it to the control system. The control system performs secondary analysis on the real-time flow volume. If the control system still judges that the outer surface of the valve head 103 is contaminated after the secondary analysis, the control system generates a cleaning instruction again, and controls the regulated gas supply device 2 and the automatic cleaning mechanism 4 to clean the contaminants again. If the control system triggers more than three cleaning instructions, the control system judges that the electric throttle valve 1 cannot be used normally, and the control system generates a fault instruction and sends a warning message to the outside through the warning device arranged in the electric control adjusting assembly 101.

[0038] In the embodiments of the present application, the specific working process of some of the embodiments is as follows: the fluid enters the flow-through cabin inside the electric throttle valve 1 through the oil inlet groove 104, the electric control adjusting assembly 101 inputs a stable working current to change the position of the valve stem 102 and the valve head 103, thereby changing the flow volume in the oil outlet groove. In this process, the regulated gas supply device 2 inputs a stable working current to generate corresponding gas and transmit it to the inside of the buffer monitoring mechanism 3, which is used to buffer the impact force generated during the fluid transmission process, further reducing the probability of deformation of the valve stem 102. At the same time, the buffer monitoring mechanism 3 monitors the shape of the valve stem 102 in real time to determine whether the buffer monitoring mechanism 3 is deformed. The regulated gas supply device 2 generates compressed air of different temperatures inside and transmits it to the inside of the buffer monitoring mechanism 3 to perform temperature adjustment on the fluid near the valve stem 102, which is used to suppress the contaminant adhesion effect induced by the change of the fluid temperature, and reduce the probability of contamination on the surface of the valve stem 102 and the valve head 103.

[0039] In the later research, we found that by adjusting the temperature of the fluid near the valve stem 102, the surface contamination coverage rate of the valve stem 102 was reduced from 35% in the traditional structure to ≤5%, and the required shear force for cleaning was reduced by 80%.

[0043] Two groups of first hollow plates 303 are installed in sequence and equidistantly on the side of the two groups of hollow long plates 301 near the valve rod 102, the annular hollow plate 302 is installed at one end of each group of first hollow plates 303 away from the corresponding group of hollow long plates 301, the other end of each group of first hollow plates 303 is arranged in the inside of the corresponding first air groove 3011, the rubber annular plate 304 is installed on the inside of the annular hollow plate 302 near the valve rod 102, a plurality of groups of springs 308 are installed in sequence and equidistantly vertically on the side of the rubber annular plate 304 near the annular hollow plate 302, one end of each group of springs 308 is vertically installed on the inside of the annular hollow plate 302, and the inductive switch 309 is installed on the inside of the annular hollow plate 302 near each group of springs 308;

[0044] One side of one group of hollow long plates 301 is installed with a conveying pipe 305, one end of the conveying pipe 305 extends to the outside of the electrically operated throttle valve 1, the other end of the conveying pipe 305 extends to the inside of the corresponding first air groove 3011, and the inside of the conveying pipe 305 is installed with a solenoid valve.

[0045] The regulating gas supply device 2 inputs stable working current to generate compressed air, which is transmitted to the inside of the first annular conveying plate 306 through a group of air outlet holes of the three-hole pipe 201. The compressed air in the first annular conveying plate 306 is transmitted to the inside of the corresponding annular hollow plate 302 through each group of first air grooves 3011 and each group of first hollow plates 303. The compressed air in the annular hollow plate 302 drives the rubber annular plate 304 to be in an expanded state. The rubber annular plate 304 in the expanded state is attached to the outer side surface of the rubber annular plate 304. There is a gap of 0.03㎜-0.05㎜ between the rubber annular plate 304 in the expanded state and the adjacent induction switch 309.

[0046] Two groups of the hollow long plates 301 are each provided with a second hollow plate 401 on the side near the valve head 103. One end of each group of the second hollow plates 401 away from the valve head 103 is arranged in the inside of the corresponding second air groove 3012. The other end of each group of the second hollow plates 401 is provided with a U-shaped plate 402. The inside of each group of the U-shaped plates 402 is in a gas mutual flow state with the inside of the corresponding second hollow plate 401. The U-shaped plate 402 is provided with a telescopic scraping plate 403 on the side near the valve head 103. The inside of each group of the telescopic scraping plates 403 is in a gas mutual flow state with the inside of the corresponding U-shaped plate 402.

[0047] The regulating gas supply device 2 inputs stable working current to generate compressed air, which is transmitted to the inside of the second annular conveying plate 307 through the other group of air outlet holes of the three-hole pipe 201. The compressed air in the second annular conveying plate 307 is transmitted to the inside of the corresponding U-shaped plate 402 through each group of second air grooves 3012 and each group of second hollow plates 401. The compressed air in the U-shaped plate 402 drives the telescopic scraping plate 403 installed on the side of the U-shaped plate 402 to be in a stretched state. When the telescopic scraping plate 403 is stretched to the limit length, it can contact the outer side surface of the bottom of the valve head 103.

[0048] In the embodiments of the present application, the specific workflow of some of the embodiments is as follows: when the fluid is transported under the action of the electric throttle valve 1, the adjustable gas supply device 2 inputs stable working current to generate compressed air, which is transmitted to the inside of the first annular conveying plate 306 through a group of air outlet holes of the three-hole pipe 201, the compressed air in the first annular conveying plate 306 is transmitted to the inside of the corresponding annular hollow plate 302 through each group of first air grooves 3011 and each group of first hollow plates 303, the compressed air in the annular hollow plate 302 drives the rubber annular plate 304 to be in an inflated state, and the rubber annular plate 304 in the inflated state is attached to the outer side of the valve stem 102; when the high-pressure fluid impacts the valve stem 102, each group of springs 308 and the rubber annular plate 304 in the inflated state will provide a group of reverse buffer forces to the valve stem 102, thereby reducing the influence of external impact force on the whole valve stem 102, and further reducing the probability of deformation of the valve stem 102;

[0049] When the control system determines that the fluid temperature near the valve stem 102 and the valve head 103 is in an abnormal range, the adjustable gas supply device 2 again inputs stable working current to generate compressed air of the corresponding temperature and transmit it to the inside of the first annular conveying plate 306, and then to the inside of each group of first air grooves 3011, to adjust the fluid temperature near the valve stem 102 and the valve head 103, while the electromagnetic valve in the delivery pipe 305 is in an open state, driving the compressed air in each group of first air grooves 3011 to be transmitted to the outside, thereby accelerating the gas flow rate in each group of first air grooves 3011, and thereby achieving the technical effect of quickly adjusting the fluid temperature near the valve stem 102 and the valve head 103. In this process, the gas volume flow rate delivered by the adjustable gas supply device 2 to the inside of the first air groove 3011 is consistent with the gas volume flow rate discharged by the delivery pipe 305, avoiding reducing the buffer force generated by the buffer monitoring mechanism 3 on the valve stem 102;

[0050] When the control system determines that the valve head 103 surface is contaminated, the control system drives the adjustable gas supply device 2 to input stable working current to generate compressed air, which is transmitted to the inside of the second annular conveying plate 307 through the other group of air outlet holes of the three-hole pipe 201, and the compressed air in the second annular conveying plate 307 is transmitted to the inside of the corresponding U-shaped plate 402 through each group of second air grooves 3012 and each group of second hollow plates 401, and the compressed air in the U-shaped plate 402 drives the telescopic scraping plate 403 installed on the side of the U-shaped plate 402 to be in a stretched state and contact the outer surface of the valve head 103, and the electric control adjusting assembly 101 inputs stable current to control the valve rod 102 and the valve head 103 to move up and down in parallel, and the valve head 103 contacts the outer side of the telescopic scraping plate 403 in the stretched state during movement, so as to automatically scrape and clean the outer surface of the valve head 103.

[0051] Referring to Figures 1 to 7 As shown in the figure, the present application provides an electrically adjustable hydraulic throttle valve, and during the operation of the electrically adjustable throttle valve 1, a group of inductive switches 309 are pressed by external force and generate corresponding electrical signals. After the control system contacts the signals, if the duration of the electrical signals exceeds 30s, the control system preliminarily determines that the valve rod 102 is subjected to a high-pressure fluid impact force exceeding the rated value. The control system adjusts the input current of the fluid transmission device arranged outside the electrically adjustable throttle valve 1, so as to reduce the delivery speed of the fluid in the oil inlet groove 104, and further reduce the high-pressure fluid impact force on the valve rod 102.

[0052] After the input current adjustment in the fluid transmission device is completed, if a group of inductive switches 309 still generate corresponding electrical signals and the duration of the electrical signals still exceeds 30s, the control system finally determines that the valve rod 102 is deformed. If a group of inductive switches 309 do not generate corresponding electrical signals or the duration of the electrical signals is less than 30s, the control system finally determines that the valve rod 102 is subjected to a high-pressure fluid impact force exceeding the rated value.

[0053] In the embodiment of the present application, the control system finally determines that the valve rod 102 is deformed, the control system drives the fluid transmission device to stop inputting current, and sends corresponding warning information to the outside through the warning device arranged inside the electric control adjusting assembly 101, reminding the staff to arrive on site for inspection. The control system finally determines that the valve rod 102 is subjected to a high-pressure fluid impact force exceeding the rated value, the control system drives the current input in the fluid transmission device, and sends corresponding warning information to the outside through the warning device arranged inside the electric control adjusting assembly 101, reminding the staff to arrive on site for inspection.

[0054] The specific workflow of the present application is:

[0055] Buffering and monitoring process: the fluid enters the flow-through cabin inside the electric throttling valve 1 through the oil inlet groove 104, the electric control adjustment assembly 101 inputs stable working current to change the position of the valve stem 102 and the valve head 103, thereby changing the flow volume in the oil outlet groove. During this process, the adjustable gas supply device 2 inputs stable working current to generate corresponding gas and transmit it to the inside of the buffer monitoring mechanism 3, which is used to buffer the impact force generated during the fluid transmission process of the buffer monitoring mechanism 3, further reducing the probability of deformation of the valve stem 102. At the same time, the buffer monitoring mechanism 3 monitors the overall shape of the valve stem 102 in real time to determine whether the buffer monitoring mechanism 3 is deformed. The adjustable gas supply device 2 generates compressed air of different temperatures inside and transmits it to the inside of the buffer monitoring mechanism 3 to adjust the temperature of the fluid near the valve stem 102, which is used to suppress the pollutant adhesion effect induced by the change of fluid temperature, and reduce the probability of pollutants appearing on the surface of the valve stem 102 and the valve head 103;

[0056] When the fluid is transported under the action of the electric throttling valve 1, the adjustable gas supply device 2 inputs stable working current to generate compressed air, which is transmitted to the inside of the first annular conveying plate 306 through a group of gas outlets of the three-hole pipe 201. The compressed air in the first annular conveying plate 306 is transmitted to the inside of the corresponding annular hollow plate 302 through each group of first gas grooves 3011 and each group of first hollow plates 303. The compressed air in the annular hollow plate 302 drives the rubber annular plate 304 to be in an inflated state. The rubber annular plate 304 in the inflated state is attached to the outer side of the rubber annular plate 304. When the high-pressure fluid impacts the valve stem 102, each group of springs 308 and the rubber annular plate 304 in the inflated state will provide a group of reverse buffering forces to the valve stem 102, thereby reducing the influence of external impact force on the overall valve stem 102, further reducing the probability of deformation of the valve stem 102;

[0057] Fluid temperature adjustment process: when the control system determines that the fluid temperature near the valve stem 102 and the valve head 103 is out of the normal range, the adjustable gas supply device 2 inputs stable working current again to generate compressed air corresponding to the temperature and deliver it to the inside of the first annular delivery plate 306, and then to the inside of each group of first air grooves 3011, to adjust the fluid temperature near the valve stem 102 and the valve head 103, while the electromagnetic valve inside the delivery pipe 305 is in the open state, driving the compressed air inside each group of first air grooves 3011 to be delivered to the outside, thereby accelerating the gas flow speed inside each group of first air grooves 3011, thereby achieving the technical effect of quickly adjusting the fluid temperature near the valve stem 102 and the valve head 103. During this process, the gas volume flow rate delivered by the adjustable gas supply device 2 to the inside of the first air grooves 3011 is consistent with the gas volume flow rate discharged by the delivery pipe 305, avoiding reducing the buffering force generated by the buffering monitoring mechanism 3 on the valve stem 102.

[0058] Contaminant cleaning process: when the control system determines that the valve head 103 surface has adhered contaminants, the control system drives the adjustable gas supply device 2 to input stable working current to generate compressed air, which is transmitted to the inside of the second annular delivery plate 307 through the other group of air outlet holes of the three-hole pipe 201. The compressed air inside the second annular delivery plate 307 is transmitted to the inside of the corresponding U-shaped plate 402 through each group of second air grooves 3012 and each group of second hollow plates 401. The compressed air inside the U-shaped plate 402 drives the stretchable scraping plate 403 installed on its side to be in a stretched state and contact the outer surface of the valve head 103. The electrically controlled adjustment assembly 101 inputs stable current to control the valve stem 102 and the valve head 103 to move up and down in parallel.
