Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
Referring to fig. 1, the present invention provides a technical solution: a gas leakage preventer specifically comprises: indicator board 1, rain-proof cap 2, body 3, big sealing washer 4, big clamp plate 5, sighting rod 6, flotation pontoon valve 7, hinge combination 8, horizontal valve 9, upper chamber 10, lower chamber 11, drain pipe 12, flange 13, pointer 14.
The shell 3 is a hollow cylinder structure with two open ends. One end of the shell 3 is sealed by the rain-proof cap 2, the rain-proof cap 2 is provided with a lifting mark post 6 in a penetrating mode, the inside of the shell 3 is provided with a buoy valve 7, the bottom of the buoy valve 7 is provided with a horizontal valve 9, one end of the mark post 6 is connected with the buoy valve 7, the inside of the shell 3 is provided with a sealing structure which is matched with the buoy valve 7 to divide the inner cavity of the shell 3 into an upper cavity 10 and a lower cavity 11, and the shell 3 is externally connected with a drain pipe 12 and is communicated with the upper cavity 10.
The sealing structure comprises a large pressing plate 5 fixed on the inner wall of the shell 3, the center of the large pressing plate 5 is in an opening shape and is used for fixing the large sealing ring 4 to form a sealing structure, and the outer surface of the float valve 7 is in close contact with the inner wall of the large sealing ring 4.
