[0002] The oil outlet valve is a one-way valve. Under the action of spring pressure, the conical surface on the upper part of the valve is closely matched with the valve seat. Its function is to isolate the high-pressure oil pipe from the upper cavity of the plunger when the supply is stopped, to prevent the oil in the high-pressure oil pipe from flowing back into the injection pump. The lower part of the oil outlet valve is a cross section, which can guide and pass diesel. There is a small cylindrical surface under the conical surface of the oil outlet valve, called the pressure relief ring belt, which is used to quickly reduce the oil pressure in the high-pressure oil pipe when the oil supply is finished, to avoid oil dripping at the spray hole.
[0003] However, in the prior art, the sealing detection of the oil outlet valve pair requires that oil be poured into the oil outlet valve pair so as to detect the tightness of the oil outlet valve pair. However, the oil used for sealing detection will dirty the fixture, which is not conducive to use. Utility Model Content

[0023] In this embodiment, the fixed plate 4 will rotate with the gear shaft as the axis. The two fixed plates 4 will rotate in opposite directions through the meshing transmission of the two spur gears 6. At the same time, the sliding cooperation between the guide block and the guide groove makes the rotation of the threaded rod 9 drive the U-shaped slider 10 to move in a straight line. The cooperation between the U-shaped slider 10 and the limit rod 7 limits the rotation angle of the fixed plate 4.
[0024] Example 2
[0025] like Figure 1-3As shown, the utility model proposes an oil outlet valve pair seal detection fixture. Compared with embodiment 1, this embodiment also includes a base 1, and a recovery box 2 for recovering oil is placed on the bottom inner wall of the base 1. Two support frames 3 are installed on the top outer wall of the base 1 through bolts. The inner rings of the two support frames 3 are both rotatably sleeved with gear shafts, and the outer rings of the gear shafts are fixedly sleeved with fixing plates 4. The two fixing plates 4 are welded with elastic clamping plates 5 for fixing the oil valve pair on one side close to each other, and the bottom of one of the fixing plates 4 is fixedly connected to a limiting rod 7, and the top inner wall of the base 1 is installed A cleaning mechanism for cleaning the oil valve pair is provided, the cleaning mechanism comprising a bearing frame 12, the bearing frame 12 is fixedly connected to a rotating shaft 13, the inner ring fixed sleeve of the rotating shaft 13 is provided with a connecting shaft 14, one end of the connecting shaft 14 is fixedly connected to a cleaning sponge 15, four cleaning sponges 15 are all located below the top opening of the base 1, both ends of the four rotating shafts 13 are fixedly connected to bevel gears 16, every two adjacent bevel gears 16 are meshed with each other for transmission, the outer ring movable sleeve of the rotating shaft 13 is provided with a torsion spring 17, the two ends of the torsion spring 17 are respectively fixedly connected to the bearing frame 12 and the bevel gear 16.
[0026] In this embodiment, when the oil delivery valve pair is inserted from above the cleaning sponge 15, multiple cleaning sponges 15 will be squeezed apart, causing them to rotate around the rotating shaft 13 connected to them. The force of the torsion spring 17 will drive the cleaning sponge 15 to always fit the outer surface of the oil delivery valve pair. When the oil delivery valve pair is pulled out, the surface parts of the oil delivery valve pair will be cleaned by the cleaning sponge 15.
[0027] Working principle: First, turning the knob 11 drives the threaded rod 9 to rotate in the inner ring of the threaded sleeve 8, and the threaded rod 9 will move through the threaded cooperation with the threaded sleeve 8. Since the threaded rod 9 is rotatably connected to the U-shaped slider 10, and the guide block fixed on the top outer wall of the U-shaped slider 10 is slidably matched with the guide groove opened on the top of the base 1, when the threaded rod 9 rotates, the U-shaped slider 10 will not rotate together, but move in a straight line. The movement of the U-shaped slider 10 will drive the fixed plate 4 connected to it to rotate through the limit rod 7. At this time, the fixed plate 4 will also drive the spur gear 6 to rotate through the gear shaft connected to it. Through the meshing cooperation of the two spur gears 6, the two fixed plates 4 will rotate in opposite directions. When the two After the fixing plates 4 drive the elastic clamping plates 5 connected thereto to open, the oil outlet valve pair is placed therein, and then the knob 11 is rotated in the reverse direction to drive the two elastic clamping plates 5 to fix it therein. At this time, the sealing detection equipment can be connected to the oil outlet valve pair, and the oil discharged from the oil outlet of the oil outlet valve pair will drip into the interior of the recovery box 2. When the oil outlet valve pair needs to be taken out, the above operation is repeated. When the oil outlet valve pair is inserted from above the cleaning sponge 15, multiple cleaning sponges 15 will be squeezed open, so that it rotates around the rotating shaft 13 connected thereto, and the cleaning sponge 15 will be driven by the force of the torsion spring 17 to always fit the outer surface of the oil outlet valve pair. When the oil outlet valve pair is pulled out, the surface of the oil outlet valve pair will be cleaned by the cleaning sponge 15.
