During concrete enforcement:
(1) stream examination fixture cavity is made
Consider that stream examination fixture will touch water, for preventing corrosion, therefore fixture inner cavity 2 adopts brass.Because fixture inner cavity 2 air pressure is comparatively large, therefore be that rubber sleeve (sealing shroud 4) is buckled with gland 6 above fixture inner cavity 2, as shown in Figure 1, to prevent, rubber sleeve (sealing shroud 4) and part (hollow blade 3) are unexpected to be gone out.
(2) rubber sleeve is made

Consider that rubber soft durometer can affect final sealing, therefore choose three kinds of rubber and carry out site test.
A: oil resistant rubber---partially hard
B: natural rubber---comparatively soft
C: silicon rubber---very soft
(3) rubber sleeve test is verified
Linking on flow tester by novel stream examination fixture by flexible pipe,---incision rubber sleeve encases rubber sleeve, and---rubber sleeve encasing blade is filled in fixture inner cavity, and------opening air valve---is stained with soap water brush in blade and rubber contact site with writing brush to buckle pressing plate, checks its impermeability.
Test findings---
A group---oil resistant rubber: after installation, opens air valve, and shown in upper figure, there is obvious gas leakage at arrow position, and because oil resistant rubber is partially hard, deflection is less, so there is fine gap between part and rubber sleeve, causes gas leakage.
B group---natural rubber: after installation, opens air valve, and without gas leak phenomenon, but natural rubber is too soft, and mounted part is difficult to take out.
C group---silicon rubber: after installation, opens air valve, and without gas leak phenomenon, silicon rubber is harder than natural rubber, so comparatively easily take out.
Conclusion: the silicon rubber effect of C group is best, therefore select C group silicon rubber as the best material of rubber sleeve on stream examination fixture.
(4) novel stream examination fixture is optimized again
Although the test effect of novel stream examination fixture is relatively good, still there are two practical problemss in operation at the scene, as:
1), after rubber sleeve parcel blade, be interference state with its fixture inner cavity, when rubber sleeve being inserted fixture inner cavity, resistance is very comparatively large, and installation process is required great effort very much.
2) although silicon rubber taking-up easier than natural rubber, because rubber sleeve coordinates closely with fixture, when batch blade stream is had a try, by manually installing taking-up, there is certain labour intensity.
Therefore continue to be further improved novel stream examination fixture.
Namely on gland 6, add a pressing plate, utilize lever principle, blade can be pressed in rubber sleeve (sealing shroud 4) smoothly, and it is time saving and energy saving to operate, as shown in Figure 3.
Meanwhile, designing and producing a special pickup device (pull-out leverage 8 as shown in Figure 3) especially, without the need to being taken out in rubber sleeve by hollow blade by finger force, having greatly reduced operator's labour intensity.
Fixture inner cavity 2 and elastometric boot (sealing shroud 4) agent structure, be beneficial to sealing and the air intake opening not current limliting of hollow blade 3.
Pressing plate (forced leverage 7) adds and pulls out part device servicing unit (pull-out leverage 8), is convenient to the installation and removal of hollow blade 3.
