Description
Technical field
This utility model relates to a kind of tank rim and seals, particularly to a kind of edge seal without oil gas in cavity between once sealing and secondary seal.
Background technology
In petrochemical industry storing technology field, for reducing the volatilization of liquid storage in storage tank, thus will in storage tank liquid storage surface configuration floating roof, for make floating roof can safe operation, being provided with sealing device between floating roof and oil tank wall, existing sealing is divided into once sealing and secondary seal.Once sealing is divided into again elastic packing, topping up to seal and mechanical seal.Secondary seal be mounted on margin plate with L-type sealing plate pressure-bearing plank frame.It is disadvantageous in that: floating roof gene basis sedimentation, tank skin install error and with pasta stir be likely to produce displacement, once sealing gap, local can be caused to strengthen, even expose pasta, oil gas overflows, and the secondary seal on top is fitted with tank skin all the time due to the effect of elastic force, oil gas cannot volatilize and be present between a secondary seal.Whether which kind of seals, and all there is oil gas between once sealing and secondary seal.Because secondary seal stops oil gas to leak.When in once sealing with secondary seal cavity, gas concentration reaches LEL, run into blast during spark.
Utility model content
Technical problem to be solved in the utility model is to provide one and has a secondary sealing function, and without the sealing device of oil-gas space between a secondary seal.
For achieving the above object, this utility model realizes by the following technical solutions:
Oil tank is without oil-gas space sealing device, between this device is arranged on tank skin and is floating roof, including upper sealing, lower seal, external seal film, static conductive element, described upper sealing includes and the sliding clamp of tank skin slipper seal, gripper shoe, upper diaphragm seal, gripper shoe is fixed on the listrium of floating roof outside by securing member, L-type sliding clamp is fixed by securing member and gripper shoe, and gripper shoe back is provided with diaphragm seal；
Described lower seal includes elastic sealing element, support member, lower platen, elastic sealing element side abuts on tank skin, opposite side is provided with support member, support member is fixed on the listrium of floating roof outside by securing member, L-type lower platen is arranged on elastic sealing element top, and it being fixed on the listrium of floating roof outside by securing member, lower seal is supported by the supporting plate being arranged on the listrium of floating roof outside；
It is provided with external seal film between lower seal and floating roof outside listrium, in lower seal is coated on by external seal film, the two ends lap hermetically of external seal film two ends and upper diaphragm seal, sealing and lower seal is made to form integral sealing, it is coated on the external seal film of elastomeric seal exterior to contact side with tank skin and be provided with saw tooth belt, elastic supporting member for supporting optical member one end is fixed on the listrium of floating roof outside by securing member, the other end becomes tip-cambered to be pressed on external seal membranous wall, external seal film is made to be close to tank skin, described static conductive element is arranged on above sliding clamp, one end is connected with sliding clamp, the other end contacts with tank skin, and along tank skin circumferentially-spaced.
Described securing member is bolt.
Described elastic sealing element is foam plastics.
Described upper diaphragm seal and external seal film adopt the rubber band of nylon fabrics both sides sulfuration kiss-coating.
Described rubber band thickness is 1.5-2.0mm.
Compared with prior art, the beneficial effects of the utility model are:
Owing to storage tank edge seal have employed integral coating formula, both existing without oil gas phenomenon between upper-lower seal, exceeding standard thus avoiding gas concentration between an original secondary seal, because thunder and lightning or electrostatic cause the phenomenon of fire and blast.Fundamentally stop the hidden danger of blast.
