Above-mentioned opener also includes door lock, and described bearing pin offers aperture, and bearing pin is pinned by the lock ring of described door lock through aperture.
Above-mentioned cylinder top is provided with and adds round seat, and multiple valve members on cylinder top are installed in and add on round seat；The outside adding round seat is provided with protective cover；Described protective cover offers multiple passage.
Above-mentioned inner barrel is 15mm steel plate, outer cylinder body be steel plate after 3mm, ceramic fibre thickness be 13mm.
Above-mentioned pillow pulling adopts steel plate all-welded structure to make.
The utility model has the advantage of:
1. cylinder wall thickness of the present utility model be chosen at meet intensity under nominal situation, rigidity and service life require while further contemplate cylinder there is ability that certain opposing is pierced through in the state of accident, simultaneously in order to reduce the risk of fire middle cylinder body blast, slow down the too fast rising of medium temperature in tank, the sufficient time is provided to accident rescue, cylinder of the present utility model is divided into three layers, is outer cylinder body, ceramic fibre and inner barrel respectively.
2., in order to Accident prevention state low head is pierced, it is provided with again one layer of protection end socket outside cylinder end socket, cylinder end socket is carried out security protection, reduces the risk that end socket is pierced.
3. cylinder body bottom lower discharge valve arranges safety device and switching mechanism, and when can avoid accident, lower discharge valve is cut off, and switching mechanism installs door lock simultaneously, can prevent the accident of stealing crude oil from occurring.
4. all for cylinder top valve members are carried out integrated, and protective cover in addition safeguard protection is set, it is ensured that accident condition next top valve member will not be cut off, and improves the reliability of cylinder.
5., in order to improve the bearing capacity of cylinder, pillow pulling all adopts all-welded structure.
