Description
Technical field:
The utility model belongs to construction machinery production field, relates in particular to a kind of pipeline water-tight test closing device.
Background technology:
In construction machinery production process, fluid pressure line, the leakage test of water lines is essential, but hydraulic oil pipe, water pipe cannot orchids or cannot directly seal end with ring flange when joint at pipe end, in the time of sealing, cannot ensure that body inside reaches enough pressure, does not reach the object of pressure testing. For this reason, we have designed a kind of pipeline water-tight test closing device.
Summary of the invention:
The purpose of this utility model is cannot orchid or sealing problem when joint at pipe end for solving hydraulic oil pipe, water pipe, and a kind of pipeline water-tight test closing device is provided.
It is to implement like this that the utility model solves the technical scheme that its technical problem adopts: a kind of pipeline water-tight test closing device, comprise retainer ring, bolt, platen, sealing gasket, pull bar, nut, it is characterized in that: retainer ring is bolted on pipe outer wall, sealing gasket is contained in platen, pull bar one end is connected on retainer ring, the other end through platen and with nut compress platen on the mouth of pipe.
There is screw thread above-described pull bar one end.
Above-described platen inside is provided with draw-in groove.
The utlity model has the advantages such as rational in infrastructure, easy to operate, sealing property is good.
Brief description of the drawings:
Fig. 1 is front view of the present utility model;
Fig. 2 is A-A cutaway view of the present utility model;
In figure: 1. retainer ring, 2. bolt, 3. platen, 4. sealing gasket, 5. pull bar, 6. nut.
Detailed description of the invention:
As shown in Figure 1 and Figure 2, a kind of pipeline water-tight test closing device, comprise retainer ring 1, bolt 2, platen 3, sealing gasket 4, pull bar 5, nut 6, it is characterized in that: retainer ring 1 is fixed on pipeline outer wall by bolt 2, sealing gasket 4 is contained in platen 3, pull bar 5 one end are connected on retainer ring 1, the other end through platen and with nut compress platen on the mouth of pipe.
There is screw thread above-described pull bar 5 one end.
Above-described platen 3 inside are provided with draw-in groove.
Embodiment: retainer ring 1 is enclosed within on pipeline, adjust the distance of the mouth of pipe, bolt 2 is evenly pressed on tube wall, pull bar 5 is threaded connection respectively the surrounding at retainer ring 1, in the inner draw-in groove of platen 3, pad after upper sealing gasket 4, penetrate on the pull bar 5 stretching out, with evenly compression platen 3 of nut 6, until the mouth of pipe is sealed completely.
