Plug closure plate spline and fill in the outside dimension of closure plate seal groove and coordinated using gap, plug closure plate spline convex surface is less than flange spline
The length of concave surface, plug closure plate spline convex surface can be entered in the concave surface of flange spline.
Sealing ring outside dimension and flange sealing surface internal diameter size mistake after sealing ring are installed on above-mentioned plug closure plate seal groove
It is full of cooperation, reaches sealing effectiveness.
The plugging technology of above-mentioned pipeline stopping transportation pressure plugging holes special three-way pipe fitting, concrete technology step are：Will be close
Seal is arranged on plug closure plate seal groove, is entered by filling in the concave surface on the convex surface alignment flange spline on closure plate spline, then
Rotating piston closure plate makes plug closure plate spline EDGE CONTACT stop to spline spacer pin, now fills in convex surface and the flange spline of closure plate spline
Convex surface overlap, so as to be fixed on the inside of pipe fitting flange, the sealing ring filled on closure plate seal groove is bonded with flange sealing surface, is reached
To seal request, so as to the technique sandwich valve required when removing operation in the state of with pressure, finally by bolt by blind plate
It is fixed on the upper end of pipe fitting flange.
Tee pipe fitting and plugging technology of the present utility model fit into position using spline, and key teeth and backing pin are determined after rotation
Position, greatly reduces part difficulty of processing, it is not necessary to which formulated, assembly manipulation is simple and easy, and production efficiency greatly improves, and keeps away
The technique for having exempted from the cylindrical reserved snap ring lockhole of old-fashioned pipe fitting, eliminates leakage hidden danger, improves security, avoid snap ring and card
The manufacturing procedure of pin.
