Detailed Description
The present invention will now be described in more detail with reference to the drawings, in which preferred embodiments of the invention are shown, it being understood that one skilled in the art could modify the invention herein described while still achieving the beneficial effects of the invention. Accordingly, the following description should be construed as broadly as possible to those skilled in the art and not as limiting the invention.
The utility model discloses a first embodiment discloses an airtight inspection device for heavy-calibre valve, as shown in fig. 1-3, it includes: the detection piece 1 of symmetrical arrangement, the opposite face of two detection pieces is provided with ring channel 2 of coaxial arrangement, detects the piece middle part and is provided with trompil 3 that link up the detection piece, detects the piece and is provided with pilot hole 4 all around, and the detection piece of mutual disposition installs adjusting screw 5 in pilot hole department, and adjusting screw stretches out the part of detecting the piece and installs adjusting nut 6, and adjusting screw 7 in the inboard of detecting the piece is installed to one of them adjusting screw who detects the piece.
With reference to fig. 3, the two symmetrically arranged insisting blocks are respectively structured as a first detection block 1a and a second detection block 1b, an annular groove is arranged on one side of the first detection block facing the second detection block 1b, and similarly, an annular groove 2 is arranged on one side of the second detection block facing the first detection block, an opening 3 coaxially arranged is arranged in the central position of the first detection block and the second detection block, the opening is used for connecting an external gas circuit, one opening is connected with a detection gas source, the other opening is used for connecting a gas source, and a large-caliber valve is installed between the two detection blocks, a valve outlet and an inlet of the large-caliber valve are respectively installed and located in the corresponding annular grooves of the detection blocks, and a sealing gasket can be installed in the annular groove for improving the sealing performance. Here the screw rod is installed in four mounting hole departments of detecting the piece to press from both sides tightly and be located the valve that detects between the piece, detect the piece here at the second and be provided with two sets of nuts, wherein a set of nut is installed in the screw rod and is stretched out the part that detects the piece, another set of nut is installed on the screw rod that the second detected the piece and towards first detection piece one side, can let the second detect the piece as fixed part through above-mentioned structure, only need adjust first detection piece and just can accomplish the tight operation of clamp of valve.
As can be seen from fig. 2, the annular groove has a square cross section, and the annular groove allows the butt joint port of the valve to be embedded therein, while the opening can be provided as a threaded hole for facilitating the butt joint of external equipment.
The device shown in fig. 3 is simple to manufacture, and is immersed in water through the valve to pressurize the pipeline inside the valve, so that if leakage occurs, gas flows outwards, and the purpose of air tightness inspection is achieved.
The utility model discloses a second embodiment provides an airtight inspection device for heavy-calibre valve, its difference with first embodiment lies in, as shown in fig. 4, two screw rod covers that detect between the piece are equipped with spring 8, because spring 8's appearance can let two detect the piece and can't laminate by oneself.
The utility model discloses a third embodiment provides an airtight inspection device for heavy-calibre valve, its difference with first embodiment lies in, see fig. 5, detect piece circumference and install rubber pad 9, this rubber pad has trapezoidal embedding portion, the stable installation of realization rubber pad that can be better through this trapezoidal embedding portion, and the rubber pad not only can protect the metal and detect the piece, can also avoid touching with the valve and appear the problem of damaging the product, and the rubber pad can let when detecting the piece installation less to the impact of basin isotructure.
The above description is only for the preferred embodiment of the present invention, and does not limit the present invention. Any technical personnel who belongs to the technical field, in the scope that does not deviate from the technical scheme of the utility model, to the technical scheme and the technical content that the utility model discloses expose do the change such as the equivalent replacement of any form or modification, all belong to the content that does not break away from the technical scheme of the utility model, still belong to within the scope of protection of the utility model.
