Abstract
The utility model discloses a door frame sealing structure for an offshore oil exploitation operating room, which comprises an operating room steel plate, a square tube, a door frame edge, a sealing strip, a door and a hinge, wherein the door frame edge is used for mounting the sealing strip; the door is opened and closed through the hinge; the operating room steel plate and the door frame edge adopt the same steel plate which is bent at the square tube and welded and fixed with the square tube; a sealing strip embedding raised edge is arranged on the door; the door frame edge is provided with an edge bending; and a door interior square tube is arranged inside the door and welded and fixed with the door. The utility model has the benefits as follows: the defect that the operating room and the door can not be sealed fully due to the serious distortion and deformation of the heated operating room steel plate and the heated square tube through large-area welding is overcome; and the sealing performance is increased, so that poisonous, harmful or combustible gases can be prevented from entering into the operating room, and the health and life safety of operators can be ensured.
Description
Technical field
The utility model relates to a kind of hermetically-sealed construction of doorframe, particularly relates to the door of offshore oil exploitation operating room and the hermetically-sealed construction between the body of chamber.
Background technology
Oil is an important energy, is the basis of world industry development, and development and national economy is played enormous function.The offshore oil exploitation industry is the poisonous and harmful of generally acknowledging, has the dangerous industry of pollution, blowout, properties of fire, and is very high to the security protection performance requirement of equipment.
The hermetically-sealed construction of existing offshore oil exploitation operating room doorframe, as shown in Figure 1, comprise operating room steel plate 1, square tube 2, doorframe edge 3, weather strip 4, door 5 and hinge 6, wherein operating room steel plate 1 directly docks with square tube 2 full welds of 60*60mm without bending, forms full weld docking location 11, square tube 2 inner rings weld doorframe edge 3 again one, be used for installing weather strip 4, agree with door 5, door 5 carries out folding by hinge 6.Square tube 2 was both used as doorframe, played reinforcement effect again.
In order to guarantee seal, need the full weld welding between operating room steel plate 1 and the square tube 2, but in actual processing and manufacturing process, operating room steel plate 1 can weld the serious distortion distortion of being heated because of large tracts of land with square tube 2, thereby cause operating room and door 5 not to seal fully, make poisonous, harmful, fuel gas enter operating room, threaten operating personnel's health and lives safety.
The utility model content
The technical problems to be solved in the utility model provides a kind of hermetically-sealed construction of offshore oil exploitation operating room doorframe, by improvement to existing operating room sash structure, reach and eliminate doorframe purpose because of the generation torsional deformation that is heated in welding process, thereby make operating room reach desired sealing grade, prevent that poisonous, harmful, fuel gas from entering operating room.
For achieving the above object, the utility model is achieved through the following technical solutions:
Design a kind of hermetically-sealed construction of offshore oil exploitation operating room doorframe, comprise operating room steel plate, square tube, doorframe edge, weather strip, door and hinge, the doorframe edge is used for installing weather strip, door carries out folding by hinge, wherein operating room steel plate and doorframe edge are block plates, this block plate is in the bending of square tube place, and is fixing with the square tube welding.Just do not need full weld between square tube and this block plate, both satisfied the demand of operating room doorframe intensity, can avoid again because of the be heated problem of the operating room seal difference that torsional deformation caused of steel plate that the large tracts of land welding causes.The no weld mark mark in surface, the outward appearance neat appearance.
In addition, Men Shangke is provided with the chimeric chimb of weather strip, promptly when door is closed, sinks in the weather strip in this chimb can part, closely contact with weather strip, and the plane contact in compared to prior art, sealing is tighter.On the doorframe edge edge bending can be set, can make like this weather strip more firm be in inside, doorframe edge, be difficult for taking place displacement and come off.Door inside can be provided with an inner square tube, and is fixing with the door welding, not yielding to increase the intensity of door, thereby avoid causing because of the distortion of door the possibility of sealing variation.
The beneficial effect of the hermetically-sealed construction of offshore oil exploitation operating room doorframe described in the utility model is: avoided because of welding the serious distortion distortion of being heated because of large tracts of land between operating room steel plate and the square tube, thereby the shortcoming that causes operating room and door not to seal fully, increased sealing, thereby avoided poisonous, harmful, fuel gas to enter operating room, ensured operating personnel's health and lives safety.
Description of drawings
Fig. 1 is existing operating room doorframe sealed structural representation.
Fig. 2 is an operating room doorframe sealed structural representation of the present utility model.
Wherein the symbol description of Fig. 1, Fig. 2 is as follows:
1, operating room steel plate, 11, the full weld docking location, 2, square tube, 3, the doorframe edge, 31, the edge bending, 4, weather strip, 5, door, 51, the chimeric chimb of weather strip, 52, the inner square tube of door, 6, hinge.
The specific embodiment
As shown in Figure 2, be operating room doorframe sealed structural representation of the present utility model.The sealing structure comprises operating room steel plate 1, square tube 2, doorframe edge 3, weather strip 4, door 5 and hinge 6, doorframe edge 3 is used for installing weather strip 4, and door 5 carries out folding by hinge 6, and wherein operating room steel plate 1 is block plates with doorframe edge 3, in square tube 2 places bending, fixing with square tube 2 welding.Just do not need full weld between square tube 2 and this block plate, both satisfied the demand of operating room doorframe intensity, can avoid again because of the be heated problem of the operating room seal difference that torsional deformation caused of steel plate that the large tracts of land welding causes.The no weld mark mark in surface, the outward appearance neat appearance.
In addition, door can be provided with the chimeric chimb 51 of weather strip on 5, promptly when door 5 is closed, sinks in the weather strip 4 in the chimeric chimb 51 of sealing bar can part, closely contact with weather strip 4, and the plane contact in compared to prior art, sealing is tighter.On the doorframe edge 3 edge bending 31 can be set, can make like this weather strip 4 more firm be in 3 inside, doorframe edge, be difficult for taking place displacement and come off.Door 5 inside can be provided with an inner square tube 52, and are fixing with door 5 welding, not yielding to increase the intensity of door 5, thereby avoid causing because of the distortion of door 5 possibility of sealing variation.
