Said support has two side plates that are installed in relatively on the said base; Between said biside plate, be installed with two parallel poles; One installing plate that can move along said pole is installed on said pole; Said second addendum cone is fixedly mounted on the said installing plate, and a screw mandrel passes screwed said side plate near said second addendum cone, one side and is connected turnably with the sidewall of said second addendum cone.
On the sidewall of said second addendum cone, be installed with a cutting ferrule, offer several screws at least on the said cutting ferrule perisporium; On the outer perimeter wall of the link that said screw mandrel is connected with said second addendum cone, offer a circle draw-in groove; When the link of said screw mandrel stretched in the said cutting ferrule, screw passed said screw and sticks into and limits said screw mandrel front and back displacement in the said draw-in groove.
On the circular cone side face of said first addendum cone and second addendum cone, also be arranged with a conical O-ring seal respectively.
The utility model is simple in structure, and is easy and simple to handle, detects applicable to the impermeability of the valve of a plurality of models.

Embodiment
To the utility model, lift a preferred embodiment at present and combine graphic specifying.Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the utility model comprises base 10, support 20, and first addendum cone, 30, the second addendum cones 40, wherein:
Support 20 is fixedly mounted on the base 10.Support 20 comprises the biside plate (21,22) that is installed in relatively on the base 10, on biside plate (21,22), is installed with two parallel poles (23,24), on side plate (21,22), offers corresponding mounting hole (not shown); Installing plate 26 is set on the pole (23,24) movably;
First addendum cone 30 is fixedly mounted in the mounting hole of side plate 21 of support 20, and its awl point is towards another side plate 22.First addendum cone 30 is for having the cone of a hollow pipeline (not shown); One end opening of this hollow pipeline is positioned at cone tip part; Another opening is positioned at the cone side-walls relative with awl point, is installed with an external pipe 31 at the hollow pipeline opening part of cone sidewall and is communicated with this hollow pipeline; At the other end of this external pipe 31 joint 32 and stop valve 33 that can connect with the external gas pressure container is installed, whether stop valve 33 may command carry gas to external pipe; Tensimeter 34 also is installed on external pipe 31, measures the pressure of gas in this external pipe through tensimeter 34;
Second addendum cone 40, its profile is identical with first addendum cone 30, is fixedly mounted on the installing plate 26, and second addendum cone 40 and first addendum cone 30 after installing are on the same axis, and its awl point is relatively.On second addendum cone 40, offer hollow pipeline (not shown); One end opening of this hollow pipeline is positioned at cone tip part; Another opening is positioned on the cone perisporium, at this perisporium place one tensimeter 41 is installed, and this tensimeter 41 is through pipeline and the open communication of opening the hollow pipeline on the cone perisporium; On the sidewall with respect to the awl point of second addendum cone 40, be installed with a cutting ferrule 42, on this cutting ferrule 42, offer several screws; Mounting hole internal fixation at side plate 22 is equipped with a trapezoidal nut 43, and screw mandrel 44 crosses this trapezoidal nut 43, and an end of this screw mandrel 44 sticks in the cutting ferrule 42, and the other end is installed with a rotatable handles 45; Stick at this screw mandrel 44 and offer a circle draw-in groove on the end perisporium of cutting ferrule 42, screw 46 passes screw and snaps in the draw-in groove, and its degree of depth that snaps in can guarantee that screw mandrel rotates, but displacement before and after can not taking place.
When the impermeability of carrying out valve detects; Valve to be checked is positioned between first addendum cone 30 and second addendum cone 40; Turning handle 45 rotates the drive installing plate through screw mandrel and moves, and moves thereby drive second addendum cone 40; Adjust the position of second addendum cone 40, make first addendum cone 30 and second addendum cone 40 push against valve openings at two ends end and carry out mechanical seal; The joint 32 of first addendum cone 30 is communicated with the external gas pressure container, opens stop valve 33, through external pipe valve internal is inflated; After reaching certain pressure, close stop valve 33, read the force value on tensimeter 34 and the tensimeter 41, if two manometric pressure values are inconsistent; Show that then there is the bad defective of impermeability in valve; If pressure value is consistent, then surperficial valve impermeability is good, belongs to the impermeability specification product.
In order further to guarantee the accuracy of air tight test; Also can on the taper surface of first addendum cone 30 and second addendum cone 40, distinguish a sheathed conical seal ring (not shown); When carrying out the impermeability detection; Can further improve first addendum cone 30, second addendum cone 40 respectively and the sealing property between the valve, guarantee the accuracy that the valve impermeability detects.
