Embodiment Construction
[0013] The present invention is described in detail below in conjunction with accompanying drawing:
[0014] as attached figure 1 The multifunctional combination test valve of the embodiment of the present invention shown includes a three-way needle valve 1 and an angle valve 2 assembled together: the two valve interfaces of the angle valve 2 are at right angles, and the valve stem 4 of the angle valve is columnar. The valve stem 4 of the angle valve is provided with a ventilation slot 7 corresponding to the valve interface perpendicular to the valve stem 4; the valve interface perpendicular to the valve stem 4 on the angle valve 2 is fitted on the needle valve 1 and faces the needle valve stem 3 on the valve interface. When in use, a pressure gauge 5 and a quick connector 6 need to be connected to the other two valve ports of the needle valve 1 respectively.
[0015] When the present invention is in use, a pressure gauge and a quick connector need to be respectively connect...
