Double-channel pipe in pipe

Abstract

The invention discloses a double-channel pipe in pipe which comprises an inner pipe and an outer pipe; the outside diameter of the inner pipe is smaller than the inside diameter of the outer pipe; thetwo ends of the inner pipe are provided with an inner inlet sleeve and an inner outlet sleeve respectively; each of the inner inlet sleeve and an inner outlet sleeve is provided with at least two positioning strips; a water channel is reserved between adjacent positioning strips; the two ends of the outer pipe are provided with an outer inlet sleeve and an outer outlet sleeve respectively; a portion of each of the outer inlet sleeve and the outer outlet sleeve extends into the outer pipe and is provided with a clamping block; the clamping blocks are matched with the end surfaces of the positioning strips in a length direction respectively so as to prevent the inner pipe from moving towards an outlet direction relative to the outer pipe along an axis; a portion of the inner outlet sleeve extends out of the outer outlet sleeve and is provided with a clamping groove; and the clamping groove is provided with a clamping ring so as to prevent the inner pipe from moving towards am inlet direction relative to the outer pipe along the axis. The double-channel pipe in pipe has the advantages that the device has a simple structure, the inner pipe and the outer pipe can be quickly assembled,and two relatively independent double channels are formed so as to facilitate connection with a double-channel four-way pipe and a double-channel faucet.

Description

technical field [0001] The invention relates to a pipe-in-pipe with dual channels. Background technique [0002] Faucets are commonly used equipment in people's kitchens. In addition to installing general faucets in the kitchen, there are also pure water faucets. This will lead to too many faucets in the kitchen, making it more messy and increasing the difficulty of cleaning in the kitchen. The solution in the past is to simply combine the pure water faucet and the tap water faucet into one, and the tap water and the purified water flow out from one pipe, which will cause the pure water to be polluted by the tap water and lose the meaning of pure water. [0003] So we redesigned a set of piping system. Both the four-way pipe and the faucet are designed as dual channels, but we still need a pipe that can connect the two and keep the two channels relatively independent. Contents of the invention [0004] The purpose of the present invention is to provide a dual-channel pipe...

[0002] Faucets are commonly used equipment in people's kitchens. In addition to installing ordinary faucets in the kitchen, there are also pure faucets. This will lead to too many faucets in the kitchen, which looks messy and increases the difficulty of cleaning in the kitchen.

The previous solution is to simply combine the pure water faucet and the tap water faucet into one, and the tap water and pure water flow out from one pipe, which will cause the pure water to be polluted by the tap water and lose the meaning of pure water
