Description
Technical field
The present invention relates to a kind of pipeline anti-impact device, particularly a kind of pipeline and equipment shock resistance connection set.
Background technique
The naval vessel can face shock problem at it during one's term of military service inevitably, and it is directly connected to fighting capacity and the vitality of naval vessel in war.Along with the development of modern military technology, make the operational environment very severe on naval vessel.High performance bomb blast is increasing to the percussion on naval vessel, makes the impact resistance of naval vessels become the strong and weak important technology index of fight capability.Even in peacetime, because the collision impact that causes that cruises also possibly cause very big injury to the naval vessel.
Warship upper pipeline system is numerous; After naval vessels are impacted by closely underwater explosion; Although hull structure is complete; But many naval vessels system equipments suffer functional destruction, as Circuit breaker tripping operation, the pipeline inipple of: circuit break, the molding material of fragility breaks, wire harness is because too tight and by garnetting, equipment and near equipment or structure interfere collision or the like.Especially the loading of ship piping system impact is very responsive, in the thump process, often occurs breakoff phenomenon owing to stress is excessive, thereby causes the naval vessel capital equipment to work, and state paralyses.The naval vessel pipe-line system spreads all over full ship; Bulky complex; Existing repeatedly sea warfare and real ship explosive test show that pipeline and equipment joint are the weak parts of whole pipe-line system; Heavy damage in impact process, occurs, so the impact failure of ship piping system is a problem that can not be ignored, especially improves the impact isolation technology of pipeline and equipment joint and the research of impact resistance and seem particularly important.
China does not also have alternative shock resistance components and parts at present; The shock resistance design of pipe-line system, the development of shock resistance components and parts and layout thereof etc. are still located blank.
Summary of the invention
Goal of the invention: to above problem; The present invention proposes a kind of pipeline and equipment shock resistance connection set; Receive when impacting in normal working or pipe-line system, can both reduce pipeline and equipment joint greatly risk of breakage takes place, play the effect of effective protection pipeline and equipment connection part.
Technological scheme: pipeline of the present invention and equipment shock resistance connection set; Comprise outer cylinder body, cylindroid helicalcoil extension spring, rubber washer, rubber cylinder cover, connecting tube and flange; The toroidal cavity that said outer cylinder body is made up of inwall, outer wall and diapire is radially evenly arranged said cylindroid helicalcoil extension spring in said toroidal cavity; The diapire of said toroidal cavity is fixedly connected with equipment; Said connecting tube inserts in the said outer cylinder body and directly is not connected with said equipment; The outside in said connecting tube insertion end has boss; Said outer cylinder body inwall is provided with the draw-in groove of the spill of mating with said boss, and said connecting tube is connected with the draw-in groove of said outer cylinder body through boss, and said flange is fixedly connected with the said connecting tube the other end.
Pipe-line system is not hit and does the time spent, and the connecting tube tube wall blocks connecting tube through the groove of outer cylinder body inwall, and connecting tube is connected with pipeline through flange, and the realization pipeline is connected with equipment, and pipeline is played normal constraint and fixing effect; Simultaneously in the cylindrical shell end, the rubber pad that is provided with of connecting tube and equipment intersection can realize water tightness and the effect that flexibly connects.After hull and pipe-line system are impacted; Because equipment is to rigidly fix, connecting tube will have the trend that is subjected to displacement because of impact, at this moment obtains device interior because connecting tube directly inserts through rubber washer; Belong to and be articulated and connected; Allow connecting pipeline winding apparatus interface to rotate, so connecting tube is minimum at the stress of this end, avoids line rupture protection valve; Displacement in various degree can take place with the amplitude of impulsive load in device outer cylinder body inner shock resistance spring on the one hand; Play the shock resistance effect; That being out of shape does not appear in protection pipeline itself is excessive, stress is excessive and produce to destroy, and still can play flexible constraint and fixation to pipeline on the other hand.
The technological scheme that the present invention further limits is: aforesaid pipeline and equipment shock resistance connection set, and in the outer wall of said outer cylinder body and the toroidal cavity between outer wall, establish altogether and be no less than 40 said cylindroid helicalcoil extension springs.
Cylindroid helicalcoil extension spring of the present invention and rubber outer cylinder body Gai Zaiwei do not bear other load except that gravity when receiving the working state of percussion; At this moment the effect of having only urceolus body wall main body to bear gravity load; Only when hull receives violent percussion; Hull structure is transmitted huge load to equipment and pipe-line system, and this moment, equipment rigidly fixed, and connecting tube has the trend of displacement; The outer cylinder body of the band spring that at this moment is connected with connecting tube begins to work; Displacement in various degree can take place along with the amplitude of impulsive load in outer cylinder body, thereby that being out of shape does not appear in protection pipeline itself is excessive, stress is excessive and produce and destroy, and still can play flexible constraint and fixation to pipeline simultaneously.Cylindroid helicalcoil extension spring is set in the outer cylinder body has reduced the risk that big displacement takes place pipeline greatly under the enormous impact loading; This device is through in the rubber pad insertion equipment and directly be not connected with equipment with connecting tube simultaneously; Realize flexibly connecting of pipeline and equipment, can effectively discharge the stress of connecting tube and equipment joint.
Aforesaid pipeline and equipment shock resistance connection set are realized flexibly connecting through direct insertion rubber pad between said connecting tube and the equipment.
Further, aforesaid pipeline and equipment shock resistance connection set are considered the impact resistance of whole device, and the place is provided with the elastic caoutchouc top cover at said outer cylinder body top cover.
Beneficial effect of the present invention: the present invention is rational in infrastructure simple, manufactures easily, and cost is low.Adopt two ends band circle shackle cylinder type spiral stretching spring as Flexible element, rubber also has elasticity, and the manufacturing technology of two ends band circle shackle cylinder type spiral stretching spring and rubber is very ripe, and quality is also very stable.
Therefore with existing pipeline and compared with techniques, the present invention has the following advantages: (1) increases the shock resistance of pipeline and equipment connection set; (2) realize flexibly connecting of pipeline and equipment, when guaranteeing normal state simultaneously the connection set distortion minimum, the fatigue life of raising connection set; (3) under the impact load effect, can reduce the stress of pipeline and equipment joint; (4) prevent that effectively pipeline and equipment joint from the risk of fracture taking place under percussion; (5) amount of deformation of effective reduction and equipment joint pipeline under the impact load effect.
