Description
Technical field
This utility model belongs to electromotor spare and accessory parts technical field, and in particular to a kind of safety is higher to be filled with clamping
The clamping sleeve blow-out patch sealing oil pipe put.
Background technology
Three big medium-oil of electromotor(Fuel oil and lubricating oil), water, the reliable cycle of gas, be to ensure that its normal work must
Standby condition.And oil transportation, hydraulic pipeline and air inlet-outlet pipe etc. are then to ensure that Oil, Water, Gas complete the important feature for circulating.Starting
In the manufacture and use of machine, seal failure gently then affects combustion rate, causes the wasting of resources and environmental pollution, heavy then may cause cause
The failure of life.
Due to many reasons such as designing, installing and using, " oil leak, leak, gas leakage " problem of electromotor is so far still
Completely solved, annoying the development of China's high-speed vehicular engine industry always.With engine power and rotating speed
Continuous improvement, while in order to meet increasingly strict Abgasgesetz, engine oil pressure is continuously increased, fuel injection system
Also a series of improvement such as Unit injector system, unit-pump system are successively experienced, finally, high-pressure common rail fuel oil injection system is occurred in that
System.Engine common rail rail pressure rises to more than 200MPa from initial 130MPa at present.Therefore, once fuel leakage,
Strong influence will be produced to engine power performance economy.What the key factor for causing the leakage of engine high pressure oil pipe is,
How the sealing of pipeline road, problem that always internal combustion engine industry pay high attention to are guaranteed under high pressure.
However, it is extremely difficult that high-pressure oil pipe sealing problem is fully solved.On the one hand, sealing mechanism is related to material
The knowledge of various ambits such as, Surface Science, hydrodynamics, lubrication theory, thermodynamics, tribology, Research on Seal itself
With regard to extremely complex;On the other hand, the lightweight of electromotor and Miniaturization Design require that its pipeline arrangement must be extremely compact, improve
Requirement to pipeline sealing part reliability.And with the increasingly raising of internal combustion engine reinforcing degree, engine oil pressure is not
Disconnected to increase, this sealing to pipeline road sealing part proposes more stringent requirement.Sealing structure self property and
The impact of local environment, more increases the difficulty to engine high pressure oil seal of tube performance evaluation.Simultaneously traditional high-pressure system
Pipeline connection more than welded using high pressure flange, welding precision has high demands, can produce the impurity such as welding slag, and pipeline dismounting, cleaning are not
It is convenient, assembling can not be repeated several times, spark is produced during welding potential safety hazard etc..To improve manufacture level, welding job is reduced
Amount and systemic contamination, improve Hydraulic system cleanliness, now to adopt ferrule-type compression joint more, and it has good resistance to pressure, resistance to
The advantages of vibratility, thermostability, and it is reusable.Welding is not required to when ferrule-type compression joint and fastener for connection, be conducive to fire prevention,
Explosion-proof and work high above the ground, can eliminate the potential safety hazard brought because of welding accidentally.Ferrule-type compression joint can be used for high temperature, high pressure and
In having the pipeline of vibration, it is ideal connector in hydraulic system.
In view of the importance and complexity of the research of engine high pressure tubing seal, Chinese scholars and related research institutes are opened
Long-term work is opened up, substantial amounts of documents and materials have been have accumulated, has been related to sealing structure oneself factor and various external environmental factors
Theory analysis, simulation calculation and experimentation to diesel engine high-pressure fuel conduit sealing property affecting laws.These factors can be returned
Receive as the following aspects:(1)Version and size;(2)Structural material;(3)Structure crudy(Surface topography, morpheme
Deviation);(4)Initial pretightning force;(5)Media flow characteristic;(6)Structural vibration.Wherein the version of oil pipe is to grind with size
The basis studied carefully with it is crucial, how to be related to a kind of higher safer electromotor sealing oil pipe of configuration flexibility and have become attack
The key of gram the problems referred to above.

Also without any special assembly tool.
When using clamping device, as shown in figure 1, enabling the hook part of the hook to hook conjunction on barb, then coordinate the post
Do not show in the other extension figures of bolt interior energy insertion, facilitate and labour-saving by stud court relative to the another of the adapter body
Direction rotates, and the adapter body can be made to fix with hold-down bolt by the hook part packing of the hook on the barb, and the folder
Attach together and packing is put between the adapter body and hold-down bolt, reach effective leak preventing effect.
As shown in figure 3, being a kind of structure of fixture of the present utility model, described fixture carries two to claw
10, between claw, distance is less than a claw width.So when oil pipe is fixed, it is only necessary to which claw is stuck on the accessory of projection
Or the raised or extension supporting with which is arranged on precalculated position and this makes it possible to make oil pipe be fixed on needs by claw
Position, if it is desired to fix two pipelines, then only needing to two fixtures are stuck by claw can be realized as.
As shown in Figure 1.Fixture is arranged on side on sleeve and is provided with dovetail groove, and opposite side is provided with and is matched with dovetail groove
The swallow-tail form of conjunction is raised.The structure is relative to being described oat tail groove structure between pipeline to the advantage of claw structure
Fixed upward stability is higher, difficult for drop-off.
Described described connector is mounted on compressing cuff-like part with pipe joint position.In order to be further ensured that pipe joint
Do not occur to reveal with the position of connector, this oil pipe is provided with compression cuff-like part and further compresses connector and pipe joint position,
Avoid the leakage of oil gas, it is ensured that the work efficiency of electromotor.
As shown in Figure 1, Figure 4, Figure 5, described compression cuff-like part includes band and band fixture, and described band is to set
The metal strip main body of buckle is equipped with, the buckle is that the reversed acanthoid being arranged in main body is raised, and the buckle in main body is in two rows
It is symmetricly set in main body, belt body fixture is the communicating structure for being internally provided with the overhead structure matched with buckle.
As shown in figure 5, described communicating structure at least two-layer, it is in opposite direction that the overhead structure of this two-layer is arranged.This
Kind of structure makes band of the present utility model two ends after around soft tube winding be also secured on band fixture, reversed acanthoid projection with
Overhead structure is engaged and makes that band is tight to wale hose connector.
One group of needle-like through hole is provided with described outer glue-line.Due to the molecular structure property of elastomeric material, long-term
In the environment of high pressure conveying air mixture medium, combustion gas can be seeped into process wire layer from inner glue layer, and in the gap in intermediate layer
Middle accumulation, accumulation to a certain extent, can cause outer glue-line bubbling even to rupture, and Some gases medium is let out by pipe joint crimping end
Leakage, causes oil pipe mass defect, or even causes security incident.To solve this technical problem, the uniform acanthopore in outer glue-line surface can
To discharge gas infiltration in time, it is to avoid flexible pipe bubbling, destruction caused by accumulated gases.
