The specific embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
Shown in Fig. 1 to 5, external tooth tube spare clamping device of the present utility model comprises overcoat 1, core pipe 2, multijaw 3, washer seat 4 and pad 5.
Overcoat 1 is cannula-like, and overcoat 1 can adopt monolithic construction or is connected in together by many sections pipes.For example, overcoat 1 comprises that sealing is connected in the first overcoat 11 and the second overcoat 12 together.The overcoat 1 interior mode that moves with the axis of energy overcoat 1 arranges core pipe 2.
Overcoat 1 is enclosed within outside the core pipe 2, and overcoat 1 and core pipe 2 are connected together with slidable mode sealing shroud.Core pipe 2 has entrance point and the port of export, and multijaw 3 is set on the outer tube wall of the port of export of core pipe 2, and multijaw 3 is three pawls or four pawls.The inwall of multijaw 3 is provided with screw thread and opens spring 32, so that multijaw 3 opens.The port of export of core pipe 2 is provided with washer seat 4 in the mode that can slide along the axis of core pipe 2, and pad 5 is housed in the washer seat 4.
As a preferred embodiment of the present utility model, if the caliber of test pipe fitting is larger, caliber＞G1/2 for example, washer seat 4 adopts split-type structural, specifically as shown in Figure 2, washer seat 4 comprises the seat of honour 41 and the base 42 that is sealed connected together, and the end at the seat of honour 41 is double-ring, the seat of honour 41 has inner tubal wall and outer tube wall, forms the spacer groove 43 of placing pad 5 between inner tubal wall and the outer tube wall.
If the caliber of test pipe fitting is less, caliber≤G1/2 for example, washer seat 4 adopts monolithic constructions, specifically as shown in Figure 3, the end of washer seat 4 is double-ring, and washer seat 4 has inner tubal wall and outer tube wall, forms the spacer groove 43 of placing pad 5 between inner tubal wall and the outer tube wall.The below describes for this all-in-one-piece washer seat 4, and split type washer seat 4 is roughly the same with it, does not repeat them here.
Embodiment one
Shown in Fig. 2 to 3, be formed with the first through hole 13a that has connection the first annular seal space 13 on the first annular seal space 13, the first overcoats 11 in the present embodiment between the first overcoat 11 and the core pipe 2.Multijaw 3 is enclosed within outside the core pipe 2 by multijaw seat 31, is formed with the second annular seal space 14 between multijaw seat 31 and the second overcoat 12, and the inwall setting of multijaw is opened and had the second through hole 14a that is communicated with the second annular seal space 14 on spring 32, the second overcoats 12.The outer tube wall evagination of core pipe 2 forms boss outward, and washer seat 4 is enclosed within on the core pipe 2 and its end face is against on the above-mentioned boss.Corresponding boss place has the hole on the core pipe 2, thereby consists of the 3rd annular seal space 15.The 3rd annular seal space 15 has the third through-hole 15a that is communicated with the first annular seal space 13.Corresponding multijaw 3 places are provided with locking hole 16 on the first overcoat 11.
When adopting the utility model clamping male element to carry out the sealing property test, at first, to stretch out the second overcoat 12 outer multijaws 3 is enclosed within outside the test pipe fitting, the first through hole 13a and the second through hole 14a are communicated with air pump by tracheae respectively, by the first through hole 13a the first annular seal space 13 is ventilated, the first overcoat 11 and the second overcoat 12 move up together, thereby the second overcoat 12 tightens up multijaw 3 and will test pipe fitting and tightly clamp, and then by locking hole 16 usefulness bolts multijaw 3 tightly is pressed against on the test pipe fitting.
Because the first overcoat 11 moves up and has opened third through-hole 15a, gas in the first annular seal space 13 enters the 3rd annular seal space 15 by third through-hole 15a, and promotion washer seat 4 moves up, pad 5 is withstood on the end face of test pipe fitting, be tightly connected thereby make to form between external tooth tube spare clamping device and the test pipe fitting.
At last, pipe fitting passes into gas or liquid carries out the sealing property test to testing by core pipe 2.Otherwise, by the second through hole 14a the second annular seal space 14 is inflated, the first overcoat 11 and the second overcoat 12 are moved down, behind the air venting in the 3rd annular seal space 15, washer seat 41 falls after rise downwards, multijaw 3 opens under the effect of opening spring 32, the test pipe fitting can be removed from external tooth tube spare clamping device like this.
Embodiment two
Shown in Fig. 4 to 5, the main distinction of present embodiment and embodiment one is by spring overcoat 1 to be resetted.
One end of multijaw seat 31 ' forms reducing diameter part 32 ', is formed with spring cavity 14 ' between this reducing diameter part 32 ' and the second overcoat 12, is provided with shift spring 15 ' in the spring cavity 14 '.The both ends of shift spring 15 ' are supported respectively on the end face of the first overcoat 11 and on the step surface of reducing diameter part 32 '.The second overcoat 12 is provided with the locking hole 16 ' that is communicated with spring cavity 14a '.In the present embodiment, replace the second annular seal space 14 with spring cavity 14 ', spring cavity 14 ' need not to adopt hermetically-sealed construction.In addition, to carry out principle and the process of performing leak test roughly the same for the test block that clamps of present embodiment and embodiment, and do not repeat them here.
The utility model simple operation, compact conformation only needs once inflation that the first overcoat 11, the second overcoat 12 and washer seat 4 are slidably reciprocated fast along the axis of core pipe 2, and charge and discharge operations is very convenient, laborsaving.
The above embodiment and accompanying drawing only are the utility model preferred embodiment, so can not limit with this scope of product form of the present utility model and style and enforcement, any suitable variation or equivalence variation or modification of doing according to the utility model claim and specification all should be considered as not breaking away from patent category of the present utility model.
