[0023] Please refer to Figure 1 、 2 , 3, 4, 5, 6, the utility model provides a technical scheme: a kind of cylinder cover measures water pressure tool, comprising: support plate 1, the both ends of the bottom of support plate 1 are equipped with the fixed part of target component that can be detached and fixed;Pipe 6 is lifted and installed in the middle of support plate 1, the bottom of pipe 6 is fixedly connected with pressing plate 7, the bottom of pressing plate 7 is fixedly connected with sealing gasket 8, the bottom of pressing plate 7 is fixedly connected with the water injection pipe 9 that communicates with pipe 6;Bolt 14 is threadedly connected with the middle of support plate 1, for pressing plate 7 is pressed on target component.

[0024] It needs to be explained that in the embodiment to the pressure test, the top of pipe 6 is connected with water pipe, the fixed part is fixed in the hole periphery needing test, then adjusting pressing plate 7 moves downward, pressing plate 7 drives sealing gasket 8 and target component to adhere and realize tight pressing, to realize sealing, to this will be through pipe 6 and water injection pipe 9 to the space of test water injection, after water injection, a period of time is observed to the numerical change of pressure gauge, to judge its sealing property.

[0025] In one embodiment, the both ends of support plate 1 are provided with adjusting hole 2, and the fixed part is magnetic base 3, the top of magnetic base 3 is fixedly connected with threaded rod 4, threaded rod 4 is placed in adjusting hole 2, and the outer side of threaded rod 4 is threadedly connected with screw nut 5.

[0026] It should be noted that in the embodiment, a cylindrical permanent magnet is installed inside the magnetic base 3, and a cast iron or other magnetic material is used as the base outside the magnetic base. By rotating the knob at the position outside the surface of the magnetic base, the direction of the two poles of the cylindrical permanent magnet inside can be controlled. When the two poles of the cylindrical permanent magnet are horizontally placed, the magnetic material is magnetized by the magnetic induction lines passing through the permanent magnet, so that the magnetic base can attract the ferromagnetic steel surface. When the two poles of the cylindrical permanent magnet are vertically placed, the base magnetic material does not pass through the magnetic induction lines of the permanent magnet or passes through few magnetic induction lines, so that the magnetic material has no magnetism or weak magnetism, and at this time the magnetic base is easy to separate from the ferromagnetic steel surface. In this way, the strong magnetic state and the weak magnetic state are switched. The engine cylinder head is made of high-strength cast iron. By rotating the tightening nut 5 outside the threaded rod 4, the position of the magnetic base 3 at the bottom of the support plate 1 is adjusted by the tightening nut 5. After the adjustment is completed, the support plate 1 is pressed and fixed between the magnetic base 3 and the tightening nut 5 by tightening the tightening nut 5. Then the position of the magnetic base 3 to be fixed is contacted. In this way, the magnetic base 3 has magnetism by the knob outside the magnetic base 3.
