The sectional perspective sectional structure chart of the O RunddichtringO ageing test apparatus that Fig. 1 provides for the utility model embodiment;
Fig. 2 be in Fig. 1 A-A to cut-open view;
In figure, 1-upper flange, 2-lower flange, 21-O-ring seal mounting groove, 3-decrement regulates pad, 4-securing member, 5-seal groove regulating ring.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, in the utility model embodiment, a kind of O RunddichtringO ageing test apparatus provided, it matches with O RunddichtringO, and test unit comprises upper flange 1, lower flange 2 and the decrement all with compressive property and regulates pad 3, and securing member 4; Wherein,
Lower flange 2 is formed with one in toroidal and opening towards the O-ring seal mounting groove 21 of upper flange 1, and certain thickness decrement is installed in O-ring seal mounting groove 21 regulates pad 3;
When O RunddichtringO is installed in O-ring seal mounting groove 21, and when being positioned at above or below decrement adjustment pad 3, by securing member 4, upper flange 1 and lower flange 2 are fastened, realize the end face that the O RunddichtringO end face relative with both upper flanges 1 fitted tightly or realized both O RunddichtringO and lower flange 2 relative mutually and fit tightly mutually.
Should be noted that, decrement regulates the thickness of pad 3 can to adjust according to the O RunddichtringO matched, by securing member 4, upper flange 1 and lower flange 2 are fastened, form upper flange 1, decrement regulates in pad 3, O RunddichtringO and lower flange 2 four and mutually fits tightly between two both ends of the surface, thus it is adjustable to realize O RunddichtringO decrement, meet the needs of the different compressibility design load of O RunddichtringO in aging test and standard; Wherein, decrement regulates pad 3 for having the metallic gasket of compressive property, thus avoids the test effect affecting O RunddichtringO because decrement regulates pad 3 compressive deformation.
Be understandable that, decrement regulates the annular radii of pad 3 equal with the annular radii of O RunddichtringO, can avoid in aging test process because of the annular radii of O RunddichtringO be less than decrement regulate the annular radii of pad 3 time, O RunddichtringO regulates the slip of pad 3 in decrement, also can avoid in aging test process because of the annular radii of O RunddichtringO be greater than decrement regulate the annular radii of pad 3 time, O RunddichtringO regulates pad 3 to stretch because of crimp towards decrement, affects the test effect of O RunddichtringO; Meanwhile, when upper flange 1 and lower flange 2 are fastened by securing member 4, decrement regulates pad 3 equal as far as possible with the degree of depth of O-ring seal mounting groove 21 with the gross thickness that O RunddichtringO is formed, thus reduces the error of aging test.
In order to avoid decrement regulates pad 3 and O RunddichtringO sliding in O-ring seal mounting groove 21, and for meeting the test of different size O RunddichtringO, therefore test unit also comprises the seal groove regulating ring 5 in toroidal, and seal groove regulating ring 5 is installed in O-ring seal mounting groove 21;
When O RunddichtringO is installed in O-ring seal mounting groove 21, a sidewall of seal groove regulating ring 5 and the madial wall of O-ring seal mounting groove 21 lean, and another sidewall and O RunddichtringO and/or decrement regulate a sidewall of pad 3 to lean.
Should be noted that, because O-ring seal mounting groove 21 has one fixed width, the O RunddichtringO that therefore can meet annular radii equal with O-ring seal mounting groove 21 width is installed, also the annular radii by changing seal groove regulating ring 5 regulates the width of O-ring seal mounting groove 21, thus meets the aging test of different size O RunddichtringO.
In the utility model embodiment, seal groove regulating ring 5 has two kinds of position set-up modes in O-ring seal mounting groove 21, specific as follows:
(1) when the least radius of seal groove regulating ring 5 equals the least radius of O-ring seal mounting groove 21, but when its maximum radius is less than the maximum radius of O-ring seal mounting groove 21, now, decrement regulates pad 3 and O RunddichtringO to be all positioned at the side of seal groove regulating ring 5 away from lower flange 2 central point;
When O RunddichtringO is installed in O-ring seal mounting groove 21, one sidewall (inwall) of seal groove regulating ring 5 and the madial wall (the side sidewall towards lower flange 2 central point) of O-ring seal mounting groove 21 lean, and another sidewall (outer wall) regulates a sidewall (inwall) of pad 3 to lean with O RunddichtringO and/or decrement;
(2) when the least radius of seal groove regulating ring 5 is greater than the least radius of O-ring seal mounting groove 21, but when its maximum radius equals the maximum radius of O-ring seal mounting groove 21, now, decrement regulates pad 3 and O RunddichtringO to be all positioned at the side of seal groove regulating ring 5 towards lower flange 2 central point;
When O RunddichtringO is installed in O-ring seal mounting groove 21, one sidewall (outer wall) of seal groove regulating ring 5 and the madial wall (the side sidewall away from lower flange 2 central point) of O-ring seal mounting groove 21 lean, another sidewall (inwall) regulates a sidewall (outer wall) of pad 3 to lean with O RunddichtringO and/or decrement, as shown in Figure 1.
Reducing to try one's best after stretching towards seal groove regulating ring 5 because of crimp in O RunddichtringO aging test process, affecting the test effect of O RunddichtringO, therefore the thickness of seal groove regulating ring 5 and the deep equality of O-ring seal mounting groove 21.
The principle of work of the O RunddichtringO ageing test apparatus in the utility model embodiment is: select corresponding decrement to regulate pad 3 according to the thickness of O RunddichtringO, and according to the corresponding seal groove regulating ring 5 of the size Selection of O RunddichtringO, by selected O RunddichtringO, after in the O-ring seal mounting groove 21 that decrement regulates pad 3 and seal groove regulating ring 5 to be arranged on lower flange 2 simultaneously, by securing member 4, upper flange 1 and lower flange 2 are fastened, thus complete the preliminary work of O RunddichtringO test, aging test can be carried out for selected O RunddichtringO specification and design compressibility.
In aging test process, to change the O RunddichtringO compressibility of this specification, then only need according to compressibility, selecting the decrement of appropriate size to regulate pad 3 to carry out replacing can realize; In aging test process, if desired the width of O-ring seal mounting groove 21 is changed to the O RunddichtringO meeting different size, the seal groove regulating ring 5 of appropriate size is then selected to change, simultaneously according to new seal groove regulating ring 5, select supporting decrement to regulate pad 3, thus form the new width of O-ring seal mounting groove 21.
Implement the utility model embodiment, there is following beneficial effect:
1, in the utility model embodiment, because test unit has compressive property, and the decrement of different-thickness can be adopted to regulate pad to carry out aging test according to the thickness of O RunddichtringO in the O-ring seal mounting groove that lower flange is offered, thus meet the needs of the different compressibility design load of O RunddichtringO and standard;
2, in the utility model embodiment, because test unit also comprises the seal groove regulating ring be arranged in O-ring seal mounting groove, the size holding O RunddichtringO in adjustable sealing circle mounting groove carries out aging test, thus meets the needs of O RunddichtringO different size design load and standard.
Above disclosedly be only a kind of preferred embodiment of the utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
