Abstract

The invention relates to a universal water drain valve for an air delivery pipe, and belongs to the technical field of gate valves. A hollow cylindrical valve shell is annularly provided with at least four valve core installation holes and at least four valve cores; the valve cores are arranged in the valve core installation holes; and the axes of the valve cores are vertical to the axis of the valve shell. The valve has a scientific and reasonable structure and low cost and is easy to produce and manufacture and convenient to install and use; the valve is used for draining water from and feeding water into an underwater non-rigid air delivery pipe under complicated installation conditions, and can work at any transverse and longitudinal installation angle; when the pipe delivers air, thevalve removes accumulated water from the pipe, avoids the phenomenon that water exists in a U-shaped pipe due to gas and the water in the pipe, reduces air delivery pressure and saves energy; when the pipe stops delivering the air and relieves the pressure, the valve allows external water to enter the pipe, keeps internal pressure and external pressure balanced, prevents the pipe from being deformed and broken due to the external pressure, and prolongs the service life of the air delivery pipe; and a filter screen is covered on the outer side of a water inlet and outlet of each valve core, sothat floating objects in the water are prevented from entering the valve shell, and impurities in the water are prevented from influencing the sealing property of the valve cores and the air deliveryefficiency of the air delivery pipe.

Description

Technical field

[0001] The invention relates to a gas pipeline drainage valve, in particular to a gas pipeline drainage valve in a complicated underwater installation environment. Background technique

[0002] Oxygenating and mixing equipment such as water-lifting aerators and stratospheric aerators are installed in reservoirs and lakes to improve the water quality of reservoirs and lakes. The oxygenation mixing equipment uses compressed air as the gas source, and is supplied by an air compressor installed on the shore through an underwater gas pipe. When installing a gas pipe in a large body of water, it is impossible to drain the water and install it under the water. Instead, tie the weight and sink to the bottom after the water surface takes over the pipe. Due to the complicated underwater terrain and undulations, only flexible pipelines such as low-density polyethylene pipes and rubber pipes can be used. The installed pipelines also fluctuate with the terrain. The beginning...
