Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic valve measurement, in particular to an electromagnetic valve measurement tool. Background Art

[0002] The solenoid valve is a control element used in aircraft hydraulic systems, which can control hydraulic reversing. The steel ball in the electromagnet is a key component to achieve the reversing function, and its stroke inside the product is also strictly required. Normally, the steel ball needs to be measured to see if its stroke meets the technical requirements when it is installed in place. However, after assembly, it is inside the product and cannot be directly measured. In addition, the stroke of the steel ball is usually small. In order to ensure the normal operation of the solenoid valve, the stroke of the steel ball needs to be measured with high precision, which makes the measurement not only troublesome, but also prone to errors, affecting the normal use of the solenoid valve.

[0003] To this end, the utility model provides a solenoid valve measuring tool. Utility Model Content

[0006] Furthermore, the threaded sleeve is threadably matched with the mounting head, and the threaded sleeve is slidably connected with the measuring rod.

[0007] Furthermore, the push plate is in contact with an end of the measuring rod away from the push rod, and a plurality of springs are fixed between the housing and the push plate.

[0013] Beneficial effects of the utility model: The utility model provides a solenoid valve measuring tool, comprising a mounting head, a push rod, a measuring rod, a housing, a push plate, a screw rod, and a pointer.

[0020] 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 described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4The utility model provides a technical solution: a solenoid valve measuring tool, including a mounting head 1 corresponding to the solenoid valve, a threaded sleeve 2 is installed at one end of the mounting head 1, a measuring rod 3 is installed in the threaded sleeve 2, a push rod 4 is fixed on the measuring rod 3, a shell 10 is installed on the mounting head 1, a push plate 5 is elastically matched in the shell 10, the push plate 5 corresponds to the measuring rod 3, a screw 6 is fixed on the push plate 5, a pointer 14 is rotatably matched on the shell 10, the pointer 14 corresponds to the screw 6, and a scale plate 15 is fixed on the shell 10.

[0022] In this embodiment, the threaded sleeve 2 is threadably matched with the mounting head 1 , and the threaded sleeve 2 is slidably connected with the measuring rod 3 .

[0023] When measurement is required, connect the mounting head 1 to the solenoid valve, then screw the threaded sleeve 2 into the mounting head 1, insert the measuring rod 3 into the threaded sleeve 2, so that the steel ball contacts the push rod 4, and then start the solenoid valve. The solenoid valve drives the steel ball to move, which can push the push rod, thereby pushing the measuring rod 3, and the stroke of the steel ball can be judged according to the moving stroke of the measuring rod 3.

[0024] The push plate 5 is in contact with one end of the measuring rod 3 away from the push rod 4. A plurality of springs 7 are fixed between the outer shell 10 and the push plate 5. A plurality of connecting rods 11 are fixed on the peripheral side of the outer shell 10. A clamping block 9 is fixed on the connecting rod 11. A clamping groove 8 is provided in the mounting head 1. The clamping groove 8 corresponds to the clamping block 9. The connecting rod 11 is an L-shaped structure. The clamping block 9 is made of elastic material. A through groove 12 is provided in the outer shell 10. The through groove 12 corresponds to the screw 6. A top block 13 is fixed on the outer shell 10. The top block 13 is an annular structure. The top block 13 corresponds to the screw 6. The top block 13 is rotatably connected to the pointer 14. The pointer 14 is threadedly matched with the screw 6.

[0025] Specifically, when measuring, the housing 10 can be mounted on the mounting head 1 through the card slot 8 and the card block 9, so that the moving range of the measuring rod 3 can be enlarged, thereby facilitating the measurement and ensuring the measurement accuracy.

[0026] As the measuring rod 3 moves, the measuring rod 3 will push the push plate 5 to move, so that the push plate 5 pushes the screw 6, the spring 7 is compressed, and the screw 6 and the pointer 14 are threadedly matched, thereby driving the pointer 14 to rotate spirally relative to the screw 6. The pointer 14 rotates to point to the corresponding scale, so that the stroke of the steel ball can be intuitively observed.

[0027] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
