Description

Technical Field

[0001] The present application relates to the field of solenoid valve technology, and in particular to a solenoid valve with a manual lever. Background Art

[0002] The solenoid valve with a manual lever is a medium-sized automatic control device. It adds the function of a manual lever on the basis of the solenoid valve, thereby improving the flexibility and control accuracy of the equipment. When the solenoid valve is energized, a magnetic field is generated in its coil, causing the magnetic core to attract, thereby changing the position of the plunger and realizing the on-off control of the fluid. When the solenoid valve is de-energized, the manual lever can manually control the opening or closing of the valve to ensure the normal operation of the equipment.

[0003] After long-term use, the plunger of the solenoid valve may get stuck and cannot be released back to its original position. At this time, it is necessary to use a manual lever to close the solenoid valve. This process may require greater force than normal to open or close correctly. The manual lever may break inside the solenoid valve body due to excessive force, improper operation or aging. At this time, replacing the manual lever will be very inconvenient.

[0039] The following is combined with Figure 1-Figure 7 This application is described in further detail.

[0040] The embodiment of the present application discloses a solenoid valve with a manual lever.

[0041] Reference Figure 1-Figure 4 , a solenoid valve with a manual lever, including a valve body 1 of the solenoid valve and a valve stem 2 for controlling the valve opening therein, and the upper surface of the valve stem 2 is fixedly connected to the lower surface of the outer protective column 3, and the upper middle part of the inner cavity of the outer protective column 3 is threadedly connected to the inner stud 31, and the middle part of the inner cavity of the inner stud 31 and the middle part of the inner cavity bottom end of the outer protective column 3 are both provided with longitudinal slide grooves 32, and the two longitudinal slide grooves 32 have the same structure and correspond to each other, and the inner cavity surface of the longitudinal slide groove 32 and the outer surface of the adjusting rod 41 are slidably arranged with each other, and the longitudinal slide groove 32 and the lower trapezoidal block 42 abut against each other and limit each other.

[0042] It should be noted that the valve body 1 and the valve stem 2 are both existing technologies, and their structural principles are not described in detail here.

[0043] The threaded connection between the inner stud 31 and the outer protective column 3 can achieve the purpose of quick disassembly and assembly, and two communicating longitudinal grooves 32 are provided in the inner cavities of the outer protective column 3 and the inner stud 31, and both are slidably arranged with the adjusting rod 41, so that the outer protective column 3 and the inner stud 31 can form a whole and be abutted and limited in the longitudinal groove 32 by the lower trapezoidal block 42, so that the outer protective column 3, the inner stud 31, and the adjusting rod 41 can form a whole, which is not easy to separate.

[0044] Reference Figure 4-Figure 6 A manual adjustment mechanism 4 is provided in the inner cavity of the outer protective column 3, and the manual adjustment mechanism 4 includes an adjustment rod 41 slidably arranged in the middle of the inner cavity of the outer protective column 3, and two telescopic grooves 46 with the same structure are opened at the lower ends of the side walls on both sides of the adjustment rod 41, and the middle part of the inner cavity of the two telescopic grooves 46 is fixedly connected to one end of the spring B47, and the other ends of the two springs B47 are fixedly connected to one side surface of two lower trapezoidal blocks 42 with the same structure, and the two lower trapezoidal blocks 42 are both slidably arranged in the inner cavity of the telescopic groove 46, and the lower trapezoidal block 42 will not be separated from the inner cavity of the telescopic groove 46 by adjusting the length of the spring B47.

[0045] Reference Figure 4-Figure 6The upper surfaces of the two lower trapezoidal blocks 42 are mutually engaged with the upper trapezoidal blocks 43, and the two upper trapezoidal blocks 43 have the same structure. The two upper trapezoidal blocks 43 are fixedly arranged on both sides of the upper part of the longitudinal slide groove 32 opened in the middle of the bottom end of the inner cavity of the outer protective column 3, and the lower surface of the lower trapezoidal block 42 is set as an inclined surface, and the upper part is set as a flat surface, while the upper surface of the upper trapezoidal block 43 is set as an inclined surface at the same angle, and the lower surface is set as a flat surface, so that the lower trapezoidal block 42 can move downward smoothly, and when subjected to an upward pulling force, it can be stuck with the lower part of the upper trapezoidal block 43 to achieve position limiting, and the lower surface of the adjusting rod 41 It is arranged to abut against the upper surface of the cross plate 44, and the lower surface of the cross plate 44 is fixed to a plurality of springs A45 arranged in an array. The best effect is achieved when the number of springs A45 arranged in the array is at least two or more, and the lower parts of the plurality of springs A45 are fixed to the bottom surface of the longitudinal slide 32 opened at the bottom of the inner cavity of the outer protective column 3, so that the cross plate 44 can move longitudinally in the longitudinal slide 32, and the length of the cross plate 44 is less than the total length of the two upper trapezoidal blocks 43 fixed on the side walls on both sides of the longitudinal slide 32, and is arranged between the two upper trapezoidal blocks 43, so that the cross plate 44 can move between the two upper trapezoidal blocks 43.

[0046] When the adjusting rod 41 drives the lower trapezoidal block 42 to slide in the longitudinal slide groove 32 and the lower trapezoidal block 42 contacts the upper trapezoidal block 43, the lower trapezoidal block 42 will be blocked by the upper trapezoidal block 43 and retracted into the telescopic groove 46 by squeezing the spring B47, and then as the adjusting rod 41 continues to move downward until the lower trapezoidal block 42 is separated from the upper trapezoidal block 43, the lower trapezoidal block 42 is pushed out under the action of the spring B47, so that the lower trapezoidal block 42 and the upper trapezoidal block 43 are mutually engaged and limited, thereby limiting the adjusting rod 41 and the outer protective column 3. When the adjusting rod 41 moves downward, it will squeeze the cross plate 44 and the spring A45. When the adjusting rod 41 breaks in the outer protective column 3, the cross plate 44 can push the released adjusting rod 41 upward, making it convenient for the staff to replace it. If the adjusting rod 41 is still inconvenient to remove, the upper opening position of the longitudinal slide groove 32 can be aligned with a flat-blade screwdriver, and then the inner stud 31 can be rotated counterclockwise to separate the inner stud 31 from the outer protective column 3, and then the adjusting rod 41 can be separated from the inner stud 31, and the replacement of the adjusting rod 41 is completed.

[0047] Reference Figure 4-Figure 7, and a release mechanism 5 is provided on the outside of the lower end of the outer protective column 3, and the release mechanism 5 includes an outer slip ring 51 rotatably provided at the lower part of the outer ring surface of the outer protective column 3, and the outer slip ring 51 and the longitudinal slide groove 32 are located on both sides of the same horizontal line and are movably penetrated by a cross bar 52, and the cross bar 52 is located at one end of the outer slip ring 51 and movably penetrates the outer slip ring 51 and the side wall of the outer protective column 3, and can be abutted against each other with the lower trapezoidal block 42, and the two cross bars 52 have the same structure and are located on the same horizontal line, and the cross bars 52 is located on the outside of one end of the outer sliding ring 51 and is provided with a spring C53, and one end of the spring C53 is fixedly connected to the outer ring surface of the outer sliding ring 51, and the spring C53 is fixedly connected to the surface of one side of the ring washer 54 on the side away from the outer sliding ring 51, and the ring washer 54 is arranged to abut against the surface of one side of the outer fixing ring 55 on the side away from the spring C53, and the outer diameter of the outer fixing ring 55 is larger than the outer diameter of the ring washer 54, and the inner diameter of the outer fixing ring 55 is larger than the outer diameter of the cross bar 52, and is arranged to slide relative to the cross bar 52.

[0048] Reference Figure 4-Figure 7 The outer ring surface of the outer fixing ring 55 is fixed with a plurality of fixing rods 56, and the outer ring surfaces of the plurality of fixing rods 56 are movably penetrated by sliding buckles 57. The one side surfaces of the plurality of sliding buckles 57 are fixedly connected to the outer ring surface of the ring gasket 54, and the structures of the plurality of sliding buckles 57 are the same. The surface of the fixing rod 56 away from the outer fixing ring 55 is fixedly connected to the outer ring surface of the outer sliding ring 51, thereby fixing the outer fixing ring 55 and limiting the ring gasket 54. The outer ring surface of the cross bar 52 at one end of the outer sliding ring 51 is provided with an external thread 58, and can be threadedly connected to the inner ring surface of the ring gasket 54, thereby enabling the cross bar 52 to move and drive the ring gasket 54 to squeeze the spring C53. When the cross bar 52 needs to be reset, the squeezed spring C53 will push the ring gasket 54 and the cross bar 52, and limit the ring gasket 54 and the cross bar 52 under the action of the outer fixing ring 55 to prevent slipping.

[0049] The outer sliding ring 51 is arranged to slide with the outer ring surface of the outer protective column 3 so that the outer protective column 3 will not drive the outer sliding ring 51 to rotate when following the rotation of the valve stem 2. When the adjusting rod 41 breaks inside the longitudinal slide groove 32, the outer sliding ring 51 can be rotated, so that the cross bar 52 can be positioned relative to the lower trapezoidal block 42, and the cross bar 52 is pushed so that the cross bar 52 and the lower trapezoidal block 42 abut against each other. When the cross bar 52 moves, it will drive the cross plate 44 threadedly connected thereto to move together, thereby squeezing the spring C53. During the movement of the cross plate 44, it will be guided by the fixed rod 56 and the slide buckle 57. The cross bar 52 moves in a straight line downward, thereby improving the docking accuracy between the cross bar 52 and the lower trapezoidal block 42, and continuing to push the cross bar 52 can push the lower trapezoidal block 42 back into the telescopic slot 46, thereby separating the lower trapezoidal block 42 from the upper trapezoidal block 43, and at the same time, the adjusting rod 41 is pushed upward under the action of the spring A45 and the cross plate 44. When the adjusting rod 41 is pushed out, the cross bar 52 is released. At this time, the ring washer 54 and the cross bar 52 are pushed in the opposite direction by the reverse action of the squeezed spring C53, and the cross plate 44 will be supported by the outer fixing ring 55 during the reverse movement to prevent the cross bar 52 from slipping.

[0050] Reference Figure 4 The cross bar 52 is movably connected to the side wall of the upper slip ring 9 at one end away from the outer slip ring 51 and protrudes a certain distance from the outer ring surface of the upper slip ring 9, so that the cross bar 52 can still maintain integrity with the upper slip ring 9 when pushing the lower trapezoidal block 42, and the middle part of the lower surface of the upper slip ring 9 is fixedly connected to the upper surface of the T-ring rod 8, and the lower part of the T-ring rod 8 and the T-ring groove 7 are slidingly arranged with each other, and the T-ring groove 7 is opened in the middle part of the upper surface of the lower fixed ring 6, so that the lower fixed ring 6 and the upper slip ring 9 can slide with each other, and the lower surface of the lower fixed ring 6 is fixedly connected to the upper surface of the valve body 1, and is fixedly connected to the outer ring of the lower surface of the top cover 10 on the upper surface of the upper slip ring 9, and the middle part of the top cover 10 is movably connected to the outer ring surface of the outer protective column 3, and the outer protective column 3 and the top cover 10 can rotate with each other.

[0051] The cross bar 52 and the upper slip ring 9 are movably arranged to pass through each other, and the cross bar 52 protrudes from the annular surface of the upper slip ring 9, so that the cross bar 52 and the upper slip ring 9 form a whole. When the cross bar 52 needs to abut against the lower trapezoidal block 42, rotating the upper slip ring 9 can drive the cross bar 52 to rotate, and then drive the entire release mechanism 5 to rotate, so as to achieve alignment with the lower trapezoidal block 42, and the lower fixing ring 6 is fixedly connected to the upper part of the valve body 1 to support the rotation of the upper slip ring 9, and through the mutual cooperation of the T-ring groove 7 and the T-ring rod 8, the upper slip ring 9 and the lower fixing ring 6 can slide and limit each other, and the top cover 10 on the upper part of the upper slip ring 9 can prevent dust from entering.

[0052] The implementation principle of the solenoid valve with a manual lever in the embodiment of the present application is as follows: when encountering a power outage or the plunger is stuck, first press the adjusting rod 41 downward so that the adjusting rod 41 drives the lower trapezoidal block 42 to move downward, and the lower trapezoidal block 42 is engaged and limited with the upper trapezoidal block 43, and then twist the adjusting rod 41 to rotate the valve stem 2. If the adjusting rod 41 is accidentally broken during the process and the adjusting rod 41 needs to be replaced in the inner cavity of the longitudinal slide groove 32 to continue the operation, the upper slip ring 9 can be rotated first to drive the cross rod 52 and the entire release mechanism 5 to rotate, and during the rotation process, it is determined whether the cross rod 52 and the longitudinal slide groove 32 are in a straight line. When the cross rod 52 and the longitudinal slide groove 32 are approximately in a straight line, the cross rod 52 is pressed inward while the upper slip ring 9 is rotated for a slight adjustment. After the cross bar 52 is docked with the lower trapezoidal block 42, continue to press the cross bar 52, so that it drives the cross bar 52 to squeeze the spring C53 and push the lower trapezoidal block 42 inward, thereby separating it from the upper trapezoidal block 43, and under the reverse action of the cross plate 44 and the spring A45, the adjusting rod 41 and the lower trapezoidal block 42 are pushed out for replacement. However, there may be a situation where the adjusting rod 41 is broken and the cross plate 44 cannot push the adjusting rod 41 out. At this time, it is necessary to use a flat-blade screwdriver to align the opening of the longitudinal slide groove 32 and rotate it counterclockwise to separate the inner stud 31 from the outer protective column 3, and then replace the adjusting rod 41, and at the same time loosen the cross bar 52. Under the action of the squeezed spring C53, the cross bar 52 is pushed back to its original position, and the replacement of the adjusting rod 41 is completed.

[0053] The above are merely optional embodiments of the present disclosure and are not intended to limit the present disclosure. Those skilled in the art will readily appreciate that the present disclosure may be modified and varied in various ways. Any modifications, equivalent substitutions, improvements, and the like made within the spirit and principles of the present disclosure shall be included within the scope of protection of the present disclosure.
