Embodiment Construction

[0008] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0009] Such as figure 1 As shown, the sealed exhaust cap of the clear water tank of the machine water vehicle includes an exhaust cap seat 1, an exhaust rainproof cover 2, a bottom plate 3, a rubber pad one 4 and a rubber pad two 5.

[0010] The exhaust cap base 1 is welded on the tank body; six ventilation holes 6 are arranged on the top of the exhaust cap base 1 . The bottom plate 3 is connected with the rainproof cover 2 of the exhaust cap through screws, and supports the rubber pad 1 4; the rubber pad 2 5 is used for sealing; The valve diaphragm blocks the clean water so that it cannot overflow; when supplying water to the aircraft, as the water in the tank decreases, a vacuum is formed in the tank, and the outside air pushes away the rubber pad to flow into the tank, so that the water supply can be carried out smoothly.

Abstract

The invention discloses a sealed exhaust cap for a clear water tank of an airplane water wagon. The sealed exhaust cap comprises an exhaust cap base, an exhaust rainproof cap, a bottom plate, a first rubber pad and a second rubber pad. The exhaust cap base is welded to a tank body, and six ventilation holes are formed in the top of the exhaust cap base. The sealed exhaust cap has the advantages that when the airplane water wagon drives, waves are formed on the clear water surface in the tank, the first rubber pad serves as a valve membrane and stops clear water from overflowing, when the water is supplied to an airplane, vacuum is formed in the tank along with reduction of the water inside the tank, external air pushes away the first rubber pad and flows into the tank, and therefore water supply can be carried out smoothly.

Description

technical field [0001] The invention relates to a sealing exhaust cap of a clear water tank of an aircraft waterwheel. Background technique [0002] Aircraft water truck clean water tank sealing exhaust cap is installed on the top of the clean water tank, used to connect the clean water tank with the outside world and maintain the normal pressure in the clean water tank. Due to the poor sealing performance of the traditional vent cap, when there is a lot of water in the can, the clean water will easily overflow to the outside through the vent cap, resulting in a waste of water resources. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a sealing exhaust cap for the clean water tank of the aircraft water truck. [0004] The technical solution for solving the above-mentioned technical problems is: a kind of sealing exhaust cap of clean water tank of aircraft water truck, comprising exhaust cap seat, ...
