Single side constant flow valve device and its fluid supply system

Abstract

A valve device and a fluid supplying system thereof. The valve device is provided with a first fluid inlet end (1-2), a second fluid inlet end (1-1) and a fluid outlet end (1-3); an operating area of an operating mechanism is divided into a mixing degree adjusting area for adjusting the mixing degree of a first fluid and a second fluid and a flow adjusting area that is always capable of adjusting the flow of the fluid outlet end (1-3) of the valve device in the whole mixing degree adjusting area; the mixing degree adjusting area is divided into a first fluid area in which the first fluid is only drained from the fluid outlet end (1-3), a mixing area in which a mixed fluid of the first fluid and the second fluid is drained from the fluid outlet end (1-3) and a second fluid area in which the second fluid is only drained from the fluid outlet end (1-3); and the flow of the operating mechanism at a minimum stop position in the flow adjusting area of the first fluid area is greater than zero, and the flow of the operating mechanism at a minimum stop position in the flow adjusting area of the second fluid area is equal to zero. The valve device and the thermal fluid supplying system thereof facilitate the conservation of fluid passing through the valve device, and facilitate normal use of a thermal fluid supplying device.

Description

technical field [0001] The invention belongs to the field of valves, in particular to the technical field of valve cores used in faucets, in particular to a single-handle double-connected water-saving valve core. Background technique [0002] As one of the most commonly used control devices in production and life, valves are used to control the state of fluid passage, such as controlling the type of fluid passing through and controlling the flow of fluid passing through. Ordinary people know and contact the most is the faucet used in daily life. According to the opening method, the faucet can usually be divided into screw type, wrench type, lifting type and induction type. The screw-type handle is opened by screwing, and when it is opened, it needs to be rotated many times to adjust the water flow through the number of turns, the more the number of turns, the greater the flow; The larger the opening angle, the greater the flow. The maximum angle is usually 90°; the lifting...

Problems solved by technology

Under the existing technology, users can only frequently adjust the hot fluid supply temperature repeatedly in the hot fluid supply device (such as a water heater), or roughly control the outlet water temperature by roughly adjusting the mixing ratio of cold water and hot water on the valve.
