A two-way flow control valve

Abstract

The invention relates to a bidirectional flow control valve which is mainly composed of a first fixed seat, a first spring, an adjusting valve, a second spring and a second fixed seat, wherein the first fixed seat and second fixed seat are connected to form a hollow cylindrical shell; the first spring, adjusting valve and second spring are positioned in an inner hole of the shell; the inner wall of the first fixed seat is provided with a first annular lug boss which protrudes inwards; a first bracket is arranged between one end of the first fixed seat away from the second fixed seat and the first lug boss; the adjusting valve is arranged in a space formed by connecting the first fixed seat and the second fixed seat; and the first spring, adjusting valve and second spring are sequentially sheathed on a first fixed column, and the tail of the first fixed column is inserted into a second locating hole of a second fixed column, so that the adjusting valve can perform the function of flow rate control no matter the liquid or gas entering the shell flows to any direction.

Description

technical field [0001] The invention relates to a two-way valve capable of controlling flow no matter whether liquid or gas in a pipeline flows in a forward or reverse direction, and belongs to the optimization technology of a flow control valve. Background technique [0002] The connection between the water pipes and the connection between the water pipe and the faucet are all realized through joints. There are generally two ways to supply water to buildings, one is to use a booster pump to send water from bottom to top, and the other is to install a water tank on the roof and use the water level difference to send water from top to bottom. No matter what kind of water delivery method is used, the water pressure of different floors will be different, which will lead to different water output on different floors. Therefore, there are now some water pipe joint designs with balanced water flow, aiming to make the water flow of different floors tend to be the same. [0003] E...

Problems solved by technology

However, in some special occasions, there may be a problem of reverse flow. The existing valves for controlling liquid volume can only control the flow in one direction. When the liquid or gas in the pipeline needs to flow in reverse, these valves cannot It plays a role in controlling the liquid volume, but it may hinder the reverse flow of liquid or gas
