Tube body is the fixed installation on tank body and is connected to mounting hole, realizes combination tube body and relief valve by the second connecting flange
Fixed connection, third connecting flange realize that branch pipe and the fixation of nitrogen envelope valve are connected to；By opening up a mounting hole on tank body just
It can realize simultaneously and promote the safety of storage tank to reduce the aperture being on tank body with the connection of nitrogen envelope valve and relief valve.
Be further arranged to: the branch pipe is extended with the connection for being located at combination tubular body towards one end of combination tube body
The port of pipe, free end towards the combination tube body of the connecting tube is arranged.
By using above-mentioned technical proposal, the setting of connecting tube for realizing branch pipe with combine the isolation between tube body, make
The air inlet and outlet for obtaining gas can have the channel oneself independently circulated, to prevent gas air inlet and while outlet process at the same time
The resonance of middle generation extends the service life of the combination unit.
Be further arranged to: the free end of the connecting tube is extended with the extended segment for being pierced by combination tube end mouth.
By using above-mentioned technical proposal, the setting of extended segment can facilitate staff to the pipeline in connecting tube and storage tank
Connection is fixed, operates the installation of staff more convenient.
It is further arranged to: it is fixed on the third connecting flange to be communicated with control pipe, it is installed on the control pipe useful
In the control valve of control on-off, the control is managed one end far from third connecting flange and is installed with to be connected for the 5th of connecting valve the
Acting flange.
By using above-mentioned technical proposal, tube body wherein one access is combined for cut off by the setting of control valve,
Extraneous disturbance factor is reduced, staff is enable to carry out more convenient maintenance to the valve for being installed on combination unit.
It is further arranged to: being installed with pressure gauge on the combination tube body.
By using above-mentioned technical proposal, the internal pressure of observation tank body can be facilitated by the setting of pressure gauge.
Be further arranged to: the control pipe is installed with the 4th connecting flange back to one end of the 5th connecting flange.
By using above-mentioned technical proposal, the setting of the 4th connecting flange can facilitate realization control pipe and branch pipe between the two
Fixed connection.
Be further arranged to: the control valve includes ball valve.
By using above-mentioned technical proposal, the setting of ball valve can realize that flow velocity is adjusted to the flow in control pipe.
In conclusion the utility model has the following beneficial effects: the utility model can be reduced the aperture being on tank body,
To promote the safety of storage tank.
