Description
Technical field
The invention belongs to engine design and technical field of measurement and test, be related specifically to the constant volume bullet form in engine fuel injector Fuel spray field.
Background technology
The windowpane form of current constant volume bullet does not have windowpane operator guards more, there will be glass press-mounting unbalance stress and to collide with phenomenon, cause windowpane damage, affect the mechanical property of windowpane in installation and removal process, causes the cracked or constant volume bullet of windowpane to leak gas.Constant volume bullet in use will often be taken a breath, and such constant volume bullet can be subject to the impact of external and internal pressure, and constant volume bullet adopts primary seal mostly at present, is difficult to ensure that constant volume bullet form can ensure sealing while buffering holds impulsive force suffered by bullet.
Summary of the invention
The object of the invention is to propose a kind of constant volume bullet form with windowpane operator guards, holding play windowpane unbalance stress and the damage problem that collides with to eliminate tradition, ensureing when being subject to impacting simultaneously, can well cushion impact forces and ensure the sealing holding bullet.
Constant volume bullet form of the present invention comprises constant volume bullet body, circular glass window, O-ring seals, the first metal washer, the second metal washer, pressing plate, bolt and nut; Described first metal washer, the second metal washer structure are identical and lay respectively at the both sides of windowpane, and the edge of the first metal washer, the second metal washer is provided with towards the annular boss of windowpane side; The surrounding of described pressing plate is provided with bolt hole, described constant volume bullet body, O-ring seals, the first metal washer, windowpane, the second metal washer, pressing plate are arranged in order, one end and the constant volume bullet body of described bolt are fixed, the other end passes pressing plate and is connected with nut, thus O-ring seals, the first metal washer, windowpane, the second metal washer is fixed between constant volume bullet body and pressing plate.
When above-mentioned constant volume bullet is under pressure impact; O-ring seals can effectively cushion; solve the problem that gasket seal can not use under high sealing pressure; but very large stress can be formed in O-ring seals sealing simultaneously to concentrate; it is infeasible for directly using on windowpane, and in the present invention, the use of two metal washers can effective head it off; can the stress equilibrium that O-ring seals is formed be passed on windowpane by metal washer, the available protecting safety of windowpane.
Further, the surface of contact of described first metal washer, the second metal washer and windowpane scribbles silica gel, this silica gel not only can strengthen the first metal washer, sealing between the second metal washer and windowpane, cushion can also be formed, to avoid acting on impulsive force on the first metal washer by glass breakage.
Further, the annular seamed edge place of described windowpane is arc-shaped transition or flanging transition, be provided with dodge recess to make to have between the annular seamed edge of windowpane and the first metal washer, the second metal washer gap or described first metal washer, the body of the second metal washer and the joint of boss, to make there is gap between the annular seamed edge of windowpane and the first metal washer, the second metal washer.Owing to having gap between the annular seamed edge of windowpane and the first metal washer, the second metal washer, therefore the annular seamed edge place of windowpane would not contact firmly with the first metal washer, the second metal washer, the stress that can reduce the annular seamed edge place of windowpane is concentrated, and avoids windowpane to damage.
Further, the gap location between the annular seamed edge of described windowpane and the first metal washer, the second metal washer is filled with silica gel, to provide better sealing and the better protection to windowpane.
Further, between described pressing plate and the second metal washer, be folded with the first rubber gasket, for the sealing improved between pressing plate and the second metal washer, simultaneously also can impulsive force suffered by heat absorbing glass window.
Further, described pressing plate is provided with step towards the edge of the one side of constant volume bullet body, is folded with the second rubber gasket between described step and constant volume bullet body, for the sealing improved between pressing plate and constant volume bullet body.
Further, between described pressing plate and nut, spring washer is installed, prevents nut from getting loose, ensure security and the sealing of constant volume bullet.
Constant volume bullet form of the present invention is by arranging the pressing plate of O-ring seals, metal washer, rubber seal and structure uniqueness, while improving sealing effectiveness, the stress that can reduce windowpane is concentrated and suffered impulsive force, effectively ensure that the security of test, stability, accuracy.
