Detailed description of the invention
Referring to figs. 1 through Fig. 7, the utility model is described further.
As shown in Figure 1, housing air-leakage test device comprises frame 0, frame 0 is provided with housing clamp for detecting air tightness, comprise brace table 1121, brace table 1121 is provided with the clamping seat 11 placing valve body 01, clamping seat 11 comprise be communicated with source of the gas air inlet 111, gas outlet 113, in the short transverse of brace table 1121, slippage is connected with and compresses the first clamping portion 3 of valve body 01, and on the width of brace table 1121, slippage is connected with the second clamping portion 2 of sealed valve body 01 port.
As shown in Figure 5, clamping seat 11 is in cylindric, air inlet 111 is opened in the side of clamping seat 11, clamping seat 11 is provided with brace table 1121, gas outlet 113 is arranged on brace table 1121, brace table 1121 is in cylindric, brace table 1121 is arranged with the sealing ring 114 abutted with valve body 01 inwall, when deployed, the inside of valve is fastened on brace table 1121, when valve is pressed on brace table 1121, the end face of valve body 01 abuts with the end face of clamping seat 11, sealing ring 114 is out of shape simultaneously, sealing ring 114 abuts with the inwall of valve body 01, increase sealing property during clamping valve body 01.
As shown in Figure 2, first clamping portion 3 comprises the first fixed head 32 and promotes the first power part 33 of the first fixed head 32 movement, first power part 33 is cylinder, cylinder is fixedly connected with frame 0, the piston rod of cylinder is fed through frame 0 and is fixedly connected with the first fixed head 32, first fixed head 32 is provided with the clamping post 31 compressing valve body 01, clamping post 31 is in cylindric, as shown in Figure 6, the end face that clamping post 31 contacts with valve body 01 is provided with groove 311, the longitudinal cross-section shape of groove 311 is rounded, the mid portion of a lot of valve body 01 all can be protruding, if the clamping post 31 of plane may contact with valve body 01 origination point, pressure is large, valve body 01 can be caused in clamping process to damage, when being provided with groove 311, it is linear contact lay when clamping post 31 contacts with valve body 01, pressure is reduced, prevent from clamping process, causing valve body 01 to damage, as shown in Figure 4, brace table 1121 is also provided with guide pillar 12, first fixed head 32 is connected with guide pillar 12 slippage, guide pillar 12 makes the mobile accuracy of the first fixed head 32 higher, namely clamping precision is higher.
