(2) in the sleeve piston cylinder is installed, the piston cylinder upper and lower side respectively with last lower sub close-coupled, have annular space between sleeve lining and the piston cylinder outer wall;
(3) the piston rod middle part has piston and seal groove, O-ring seal is housed in the groove, the piston cross-sectional area presss from both sides the maximum cross-section area greater than test piece, piston is installed in the piston cylinder, underpart of the piston rod passes pipe nipple and gate valve, top connection is passed on top, and handle is installed in the top, is separately installed with O-ring seal between top connection, lower sub and the piston rod;
(4) has the through hole that connects annular space between its center pit and sleeve and the piston cylinder in the lower sub, the aciculiform valve rod is installed on through hole, through hole also having annular space and space outerpace between coupling sleeve and the piston cylinder in the lower sub is equipped with plug screw on the through hole;
(5) having the through hole that connects the annular space between piston bore inner chamber and sleeve and the piston cylinder in the top connection, have the gap between top connection bottom and the piston rod, seal between top connection top and the piston rod.
In technique scheme, be connected with space outerpace at the through hole that connects the annular space between piston bore inner chamber and sleeve and the piston cylinder in the top connection, tensimeter is installed on it.
The utility model has the advantages that to be applicable on the high pressure line that test piece is laid or taking-up work under the band pressure condition, and is safe and convenient to use, after installation or taking-up finish, this device can be taken off, do not occupy the space around the pipeline, solve the problem that high pressure line picks and places test piece.
Fig. 1 is a structural profile synoptic diagram of the present utility model.
