[embodiment]
The below mainly is described in further detail sealing test device in conjunction with the drawings and the specific embodiments.
As shown in Figure 1, the O-ring seal 200 that the sealing test device 100 of present embodiment is mainly used in light fixture carries out different decrements tests, thus select corresponding particular stiffness and wire diameter O-ring seal 200 the optimal compression amount or be chosen in optimum hardness and the wire diameter of the O-ring seal 200 under the specific compression amount.Sealing proving installation 100 mainly comprises seal 110 and gland bonnet 120.
As shown in Figure 2, it is cylindric that seal 110 roughly is, an end sealing, other end opening.Seal 110 is provided be used to the seal groove 111 that holds O-ring seal 200 with along the circumferential limited step 112 that distributes of seal 110.Seal groove 111 is in the openend setting near seal 110.Limited step 112 axially has different height seal 110, and is easy to operate, and each limited step 112 equal altitudes setting successively raises or reduction etc. such as (openend up) clockwise.In other embodiments, each limited step 112 can not need the equal altitudes setting.
Preferably, the seal 110 of present embodiment is made of urceolus 113 and inner core 114 cooperations.Urceolus 113 1 end sealings, the sheathed inner core 114 of the other end.Inner core 114 both ends opens, wherein an end is fixed on urceolus 113, and another open end edge arranges O-ring seal 200.The external diameter of urceolus 113 is greater than the external diameter of inner core 114.Limited step 112 is arranged on urceolus 113.Further preferred, urceolus 113 is poor with the external diameter of inner core 114 consistent with width limited step 112.For reaching sealing property preferably, urceolus 113 is preferably one-body molded with inner core 114.On inner core 113, corresponding each limited step 112 is provided with for spacing hole 115.Each spacing hole 115 is along the axial equal altitudes setting of inner core 114, and the difference in height of adjacent spacing hole 115 is consistent with the difference in height of corresponding adjacent limited step 112.Be to guarantee the sealing property of sealing test device 100, the spacing hole 115 of present embodiment is offered but is not run through the barrel of inner core 114 from the outer wall of described inner core 114.
As shown in Figure 3, gland bonnet 120 is used for sheathed with inner core 114, coordinates O-ring seal 200 is carried out the decrement test.It is cylindric that gland bonnet 120 roughly is, an end sealing, other end opening.As shown in Figure 4, the inwall of gland bonnet 120 is circumferentially with different inner diameters sealing surface 122.Preferably, the internal diameter of sealing surface 122 successively decreases successively from openend to the blind end near gland bonnet 120, and the width of sealing surface 122 is consistent with the height of limited step 112.The decrement corresponding to sealing surface 122 of different inner diameters, thereby corresponding different sealing grades.
The gland bonnet 120 of present embodiment is provided with the positioning step 124 that coordinates with limited step 112 at openend.Positioning step 124 is along the circumferential setting of cylindric gland bonnet 120, and the difference in height of adjacent positioned step 124 (height of positioning step 124) is consistent with the difference in height (height of limited step 112) of adjacent limited step 112.Gland bonnet 120 is provided with the pilot hole 126 that coordinates for each spacing hole 115 on lowest positioned step 124.Pilot hole 126 runs through the barrel of gland bonnet 120.
Please in conjunction with Fig. 1, correspondingly, sealing test device 100 also includes the reference column 130 that is used for gland bonnet 120 location that coordinates with spacing hole 115 and pilot hole 126.Reference column 130 inserts by pilot hole 126 and is used in spacing hole 115 gland bonnet 120 is positioned at suitable limited step 112.Spacing hole 115 and pilot hole 126 can be jack or screw, and corresponding reference column 130 can be latch or screw etc.Further preferred, for guaranteeing the sealing property of sealing test device 100, sealing proving installation 100 can also include the element (not shown) such as sealing gasket adaptive with reference column 130.
when needs are measured the sealing property of O-ring seal 200 under different decrements, at first O-ring seal 200 is placed in seal groove 111, again successively with gland bonnet 120 from the sealing surface 122 of maximum inner diameter successively to the sealing surface 122 and O-ring seal 200 fitted seal of minimum diameter, because the width of sealing surface 122 is consistent with the height of limited step 112, the height of positioning step 124 is consistent with the height of limited step 112, during operation, only needing rotary seal lid 120 minimum positioning step 124 to be positioned on the limited step 112 of differing heights gets final product, test again the sealing property of whole system (sealing test device 100 and O-ring seal 200), due to decrement corresponding to the sealing surface 122 of different inner diameters, the sealing grade that different decrements is corresponding different, thereby select to have the decrement of sealing surface 122 correspondences of optimal compression amount as design parameter, the hardness of fitted seal circle 200 and wire diameter parameter are carried out the production of O-ring seal 200.
The sealing test device 100 of present embodiment is stainless steel, in other embodiments, can also be the rigids such as aluminium alloy, bronze.
sealing proving installation 100 is by the limited step 112 of design differing heights on seal 110, fitted seal is covered positioning step 124 and the sealing surface 122 on 120 again, decrement is adjustable, for the O-ring seal 200 with certain degree of hardness and wire diameter, select different sealing surface 122 to carry out the sealing property test, the decrement corresponding to sealing surface 122 of different inner diameters, can determine comparatively easily the optimal compression amount of O-ring seal 200, thereby can reduce design iterations sealing strip in test process, the design parameter of disposable definite O-ring seal 200 that can be comparatively easy.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
