Embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
As shown in Figures 1 to 4, valve seal pick-up unit of the present utility model, comprise erecting frame 1, test block mount pad 2, cylinder 3, sealing pressure head 4 and observation tube 5.
Erecting frame 1 comprises top board 11, base plate 12, side plate 13 and backboard 14.Three limits that top board 11 is adjacent with base plate 12 link together by side plate 13 and backboard 14 respectively.Two recessed formation recesses 131 of side difference that side plate 13 is relative with backboard 14.
Test block mount pad 2 is provided with multi-ring annular boss 21,21 two kinds of set-up modes of boss: 1, multi-ring annular boss 21 stacks up and down, and the diameter of every circle boss 21 from top to bottom becomes greatly, and the diameter of each ring shape boss 21 is the valve of corresponding a kind of specification respectively.2, multi-ring annular boss 21 snare one circle from inside to outside, the diameter of each ring shape boss 21 is the valve of corresponding a kind of specification respectively.During the test valve, the test valve of different size is placed on respectively on corresponding boss 21 and gets final product.
Whether whether observation tube 5 is transparent, when having water in observation tube 5, during detection,, if gas is arranged by sealing the passage 41,23 in pressure head 4 and test block mount pad 2, can observe directly in the water in observation tube 5 and have Bubble formation or water level can rise.
The corresponding test block mount pad 2 in the test side of inductive switch 6 arranges, and the output terminal of inductive switch 6 connects the control end of cylinder 3 or oil cylinder.
While detecting the sealing property of valve 1a, first discharge water in observation tube 5, valve 1a is closed and is placed on test block mount pad 2 again, the entrance point of valve 1a and endpiece be corresponding sealing pressure head 4 and the test block mount pad 2 of pointing to respectively, the endpiece of valve 1a is enclosed within on boss 21, the end face of valve 1a is against on O type circle 22, as shown in Figure 3.Also can turn the entrance point of valve 1a and endpiece around placement.The test side of inductive switch 6 detects on test block mount pad 2 and is placed with valve 1a, the output terminal of inductive switch 6 is to 3 one enabling signals of cylinder, the piston rod of cylinder 3 stretches out and drives 4 declines of sealing pressure head and is pressed on the entrance point of valve 1a, and then by the passages 41 in sealing pressure head 4, inputs gas in valve 1a.
If there is leakage phenomenon in valve 1a, gas enters observation tube 5 by the passage 23 in the passage 41 in sealing pressure head 4, valve 1a, test block mount pad 2, and the water in observation tube 5 can produce bubble, and this sealing property that shows valve is poor.Otherwise,, if the water in observation tube 5 does not have Bubble formation, show the favorable sealing property of this valve 1a.The utility model detection loading and unloading are convenient, simple to operate, and versatility is good, and testing result is observed very directly perceived.
And the side plate 13 direct detection personnel's of erecting frame 1 a recessed formation recess 131 of side, the guide pole 15 of assistant cylinder 3 liftings is set on top board, can form very large detection operating space, the testing staff operates easily, can not hamper operation.
Contact because test block mount pad 2 can both form good sealing with endpiece with the entrance point of valve 1a with sealing pressure head 4, adopt the utility model also can improve the degree of accuracy that valve seal detects, and be applicable to all kinds of valves, such as ball valve, gate valve etc.
The above and accompanying drawing are only the utility model preferred embodiment, therefore can not limit with this scope of product form of the present utility model and style and enforcement, any suitable variation or equivalence of doing according to the utility model claim and instructions changes or modifies, and all should be considered as not breaking away from patent category of the present utility model.
