A special valve for pressurized water storage equipment

Abstract

The invention belongs to the technical field of air inlet valves of pressure-bearing water storing devices and particularly relates to a valve special for a pressure-bearing water storing device. The valve special for the pressure-bearing water storing device mainly solves the technical problems that an existing valve special for a pressure-bearing water storing device is opened manually and is not convenient to use and poor in sealing performance and water leaks from an air inlet valve. The valve special for the pressure-bearing water storing device comprises an air filtering device, an air inlet device, an air inlet and outlet control device, a guiding frame, a valve body and a valve cover. The upper portion of the guiding frame is arranged on a boss on the middle upper portion of an inner cavity of the valve body, and the air inlet and outlet control device is arranged on the upper portion of the inner cavity of the valve body so that a floater can be located in the guiding frame. The valve cover is connected with the upper portion of the valve body, and the air inlet and outlet control device is fixed in the inner cavity of the valve body. An inner screw hole of a connection bend of the air inlet device is connected with the upper portion of an air inlet nozzle of a valve element of the air inlet and outlet control device, and the air inlet device is arranged on the upper end face of the valve cover. The filtering device is arranged on the valve cover and covers the air inlet device. The valve special for the pressure-bearing water storing device has the advantages that high sensitivity and automatic opening are achieved, the sealing performance is good and water does not leak when faults exist.

Description

technical field [0001] The invention belongs to the technical field of air intake valves for pressurized water storage equipment in water supply systems, and in particular relates to a special valve for pressurized water storage equipment. Background technique [0002] The pressurized water storage device is a water storage unit in the water supply system. Under the condition of normal water supply in the water supply system, the pressurized water storage device is only a part of the pipeline and has a water pressure equal to the water supply pressure. When the water supply fails (such as insufficient water pressure, pipeline damage, equipment maintenance, etc.), the water stored in the pressurized water storage equipment can continue to provide users with domestic and production water. When the pressurized water storage equipment is in use, when the external water supply system stops water and negative pressure is formed at the high level of the pipeline system, although th...
