Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in figure 1, the utility model includes being provided with outer tooth fixture 7 and interior tooth fixture 8 on outer cover 4, the outer cover 4,
Water filling gas injection core 10 is provided with the outer tooth fixture 7 and interior tooth fixture 8, the water filling gas injection core 10 is connected with cylinder 6, described
Conversion socket 11 is provided with outer cover 4, the port of export of outer the tooth fixture 7 and interior tooth fixture 8 connects with the conversion socket respectively
Connect, the conversion socket includes being provided with and the conversion plug below annulus seat 5 and multigroup connector 2, the conversion socket
At least two groups lock pins are provided with the changeover plug 11 that seat coordinates, the changeover plug 11, first group of lock pin is inserted for water filling
Core 9, second group of lock pin is gas injection lock pin 12.
O-ring seal is provided with described in two groups on lock pin, detection sealing is improved.
It is provided with the outer cover 4 apart from adjustment tank 1, it is described that regulation fixture block 3, the tune are provided with adjustment tank 1
The one end of one end of fixture block 3 respectively with outer the tooth fixture 7 and interior tooth fixture 8 is saved to be connected.
The annulus seat 5 is rotary type annulus seat, and the annulus seat 5 is connected with the output end of electric rotating machine.
Operation principle of the present utility model is as follows：
In use, the port of export of the test fixture on outer cover 4 is rotated into the concordant position of the correspondence of changeover plug 11
Postpone, start cylinder 6, cylinder axis push up changeover plug 11, and the lock pin on changeover plug 11 will insert conversion socket
After connecting hole, the seal gasket on lock pin seals to form airtight cavity, to the water swivel on changeover plug 11 according to examination criteria
Required pressure value injects water, and water can be injected into by the water filling lock pin 9 on conversion socket again by lock pin again by water swivel
The water filling core of fixture is injected into leading cavity, the sealing property to detect tap.
The utility model can be transformed into corresponding fixture at any time according to different product, by the lock pin on plug,
The gas that cylinder needs, the water body for having pressure to be needed during detection is injected separately into the cylinder and tap of fixture, realizes test
Sealing property of the pipe under inner pressuring load effect, realistically simulates pipeline actual condition, simple in construction, workable, real
With conveniently.
Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model
Any modifications, equivalent substitutions and improvements made within new spirit and principle etc., should be included in guarantor of the present utility model
In the range of shield.
