Detailed Description
The utility model is further described below with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present utility model more apparent, the present utility model will be further described in detail below with reference to the accompanying drawings and detailed description. It should be understood that the detailed description is presented by way of example only and is not intended to limit the utility model.
Referring to fig. 1, a butterfly valve disc tightness detection device comprises an upper die 1 and a lower die 2, wherein an air inlet pipe 3 is formed at the top of the upper die 1, an upper die cavity 4 is formed at the lower part of the upper die, the air inlet pipe 3 is communicated with the upper die cavity 4, a lower die cavity 5 is formed in the lower die 2, the lower die cavity 5 is of a stepped hollow structure, an elastic membrane 6 is paved at the bottom of the lower die 5, and the lower part of the elastic membrane 6 is fixed by a fixing ring 7, so that the elastic membrane 6 is in an unfolding state; the bottom of the upper die 1 is provided with a positioning ring 8, and the top of the lower die 2 is provided with a positioning groove 9 which are matched with each other. Specifically, the work piece is placed in the lower cavity 5 of the lower die 2, then the upper die 1 is moved down by the cylinder to close the upper die 1 and the lower die 2, and then the air tightness of the butterfly valve disk is detected by inputting high-pressure air into the air intake pipe 3 and observing whether the elastic membrane 6 is deformed or not.
In this embodiment, the bottom of the lower die 2 is provided with an annular groove, the upper surface of the fixing ring 7 is provided with an annular pressing block 10, and the annular pressing block 10 presses the outer part of the elastic membrane 6 into the annular groove, so that the elastic membrane 6 is ensured to be fixed, and air leakage at the joint is avoided.
In this embodiment, an air bag groove is formed in the inner wall of the positioning groove 9, an air bag 11 is embedded in the air bag groove, and an air nozzle 12 is arranged in the air bag 11. After the air bag 11 is inflated, gaps between the positioning ring 8 and the positioning groove 9 are filled, so that the tightness between the upper die 1 and the lower die 2 is improved, and air leakage is avoided.
In this embodiment, the inner wall of the fixing ring 7 is provided with a pressing ring 13, the section of the pressing ring 13 is in an L-shaped structure, and the pressing ring 13 is embedded into the fixing ring 7 to press and fix the elastic membrane 6. The compression ring 13 further fixes the elastic die 6 to avoid air leakage at the joint.
The foregoing is merely illustrative of the present utility model and not restrictive, and other modifications and equivalents thereof may occur to those skilled in the art without departing from the spirit and scope of the present utility model.
