For ease of being installed in place shearing-resistance blocks, the upper surface of shearing-resistance blocks and the contact surface of threaded pressure ring inwall annular groove have
The taper being meshed.
The utility model can also equally open up confession shearing-resistance blocks corresponding with shearing-resistance blocks thickness on the inwall of cylinder and insert
Annular groove, shearing-resistance blocks are arranged on sealing-plug, threaded pressure ring and cylinder inboard wall simultaneously, cylinder, threaded pressure ring and sealing-plug
Shearing-resistance blocks, can share a part of axial force of threaded pressure ring, ensure that sealing-plug and threaded pressure ring in pressure while sealing
The stability connected on force container cylinder.
One end that screw rod described in the utility model is located at outside cylinder is provided with operating handle, and convenient operation exists screw rod twist-on
On the sealing-plug of cylinder, threaded pressure ring and inside.
Sealing-plug axial centre position described in the utility model is provided with pressure sensor, can be with monitoring pressure in real time container
Internal pressure puts on the axial force on sealing-plug.
The mounting hole through radial direction is offered on threaded pressure ring described in the utility model.Because threaded pressure ring and cylinder inboard wall
Between be threaded connection, and the connection of threaded pressure ring has to closely, it is not possible to have loosening, so setting mounting hole, in stubborn spiral shell
In the later stage of line, operating handle is set in the mounting hole, is easy to staff to operate and exert a force.
The utility model has the following technical effect that using after said structure：
The initial stage that the utility model is started working in container, sealing ring is a kind of movable sealing structure, it is possible to achieve just sealed
Do not leak, with pressure vessel, operating pressure is gradually risen, and sealing-plug is being moved axially upwards, so as to compress sealing ring, reach
To the effect of self-tightening sealing.Annular groove and shearing-resistance blocks are opened up on sealing-plug simultaneously, by the installation of screw action shearing-resistance blocks with
Shearing-resistance blocks, i.e., moved to operating position and be arranged on cylinder outside with removed position, the operating side of screw rod is shifted onto by dismounting using screw rod,
Easy installation and removal.
The shearing-resistance blocks of threaded pressure ring and sealing-plug, can share a part of axial force of threaded pressure ring, while sealing
