Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Referring to Fig.1, it is a kind of pipeline valve pressure testing device disclosed by the utility model, including frame 11 and is located at frame 11
On pressure device, pressure device is divided into operation part and fixed part.
Frame 11 is welded using profile (channel steel, I-steel or square tube etc.), and guide pad 12 is welded on frame 11
On top surface.It is vertically provided with a threaded hole at the center of guide pad 12, screw rod 13 is installed in threaded hole, on the lower end of screw rod 13
It is connected with equal briquetting 3, upper end is welded with operation handle 4.Upper blind plate 14 is welded on the bottom surface of equal briquetting 3.
Pressure pump 52 is placed on the side of frame 11, can also be with being bolted directly to frame when its volume is smaller
On frame 11.
Check valve 6 is connected on the output end of pressure pump 52, the other end of check valve 6 is connected with conduit 51, conduit 51
End is connected with pressure gauge A53.
Pipeline 22 is connect with the middle section of conduit 51, is equipped on the conduit 51 between junction and pressure gauge A53
It is vented valve 54, pressure gauge A53 is installed on the conduit 51 between junction and pressure gauge A53.
Referring to Fig. 2, the specific structure of screw rod 13 and equal 3 junction of briquetting are as follows: 13 lower end of screw rod is provided with a link slot 71,
It is provided with the connecting hole to match with screw rod 13 72 on the top surface of equal briquetting 3, is screwed with screw 73, spiral shell on the side wall of connecting hole 72
Silk 73 is extend into the link slot 71 of 13 lower end of screw rod after the side wall of connecting hole 72.
The implementation principle of the present embodiment are as follows:
