[0017] See Figs. 1 to 4 The utility model embodiment discloses a sealing property combined tool mainly comprises joint body, and the joint body is further subdivided into import joint 6 and export joint 1, and the two parts are closely connected through connecting piece, form a closed test system, can safely bear the gas pressure required by test.

[0018] One end of import joint 6 is provided with positioning groove, and the positioning groove is annular structure, is used for accurately clamping the end of one-way valve 4 body, and the whole end is contained in the inside of positioning groove, and the central position of positioning groove is equipped with a convex ring, and the convex ring is closely butted with the inner wall of one-way valve 4 body end, ensures the stability of one-way valve 4 when installing, in addition, the outside of convex ring is also equipped with copper gasket 5, to enhance sealing effect and protect one-way valve 4 from damage.

[0019] The inside of the outlet joint 1 is provided with a mounting groove specially used for accommodating the one-way valve 4 body, the depth of the mounting groove is greater than or equal to the length of one end of the one-way valve 4 body, so as to ensure that one end of the one-way valve 4 body can be completely inserted and stably fixed, and a sealing groove is designed on the side of the one-way valve 4 body and used for mounting a sealing element, the sealing element is composed of an O-shaped ring 2 and a check ring 3, the O-shaped ring 2 is arranged at one end close to the outlet joint 1 and provides a main sealing effect, and the check ring 3 is used for preventing the O-shaped ring 2 from being extruded during the test, so as to ensure the durability and reliability of the sealing.

[0020] One end of the outlet joint 1 is also provided with a connecting piece connected with the inlet joint 6, the connecting piece is in the form of a connecting nut 101 and is tightly connected with the outer wall of the positioning groove through threads, so that the one-way valve 4 body can be quickly installed between the inlet joint 6 and the outlet joint 1 in use, the sealing property is maintained while a certain pressure is maintained, and different degrees of the connecting nut 101 can be selected according to the length of different one-way valve 4 bodies, so that the one-way valve 4 bodies of various specifications can be applied, the use effect is ensured, and the sealing property is improved.
