Novel drinking water pipe, cold and hot water two-way pipe and connector of novel drinking water pipe

Abstract

The invention relates to the technical field of water pipes, and discloses a novel drinking water pipe, a cold and hot water two-way pipe and a connector of the novel drinking water pipe. The novel drinking water pipe comprises an inner pipe and an outer pipe, wherein the outer pipe is a plastic pipe, the inner pipe is made of a silicate material, the silicate material is one of enamel, cement andglass, and a layer of thermal insulation pipe is arranged between the inner pipe and the outer pipe. The cold and hot water two-way pipe comprises an outer plastic pipe and three pipes wrapped in a thermal insulation material, wherein the three pipes refer to a water inlet pipe used for cold water, a water outlet pipe used for hot water and a control pipe used for electric wires. The connector comprises a straight connector body, an elbow and a three-way connector body and consists of an outer plastic pipe and an inner glass pipe. The connector is welded with the plastic outer pipe of the water pipe through the outer plastic pipe so as to achieve connection with the drinking water pipe. A metal pipe with internal threads is arranged in the connector to achieve connection with a faucet. After drinking water passes through the water pipe, the drinking water only contacts with the silicate material, does not dissolve toxic and harmful substances, and has the advantages of corrosion resistance, no toxicity, sanitation and convenient installation.

Description

technical field [0001] The invention relates to the technical field of water pipes, in particular to a novel drinking water pipe, a hot and cold double-way pipe and a joint thereof. Background technique [0002] At present, water pipes are mainly divided into three types: metal pipes, plastic pipes, and plastic composite metal pipes. Metal pipes include galvanized pipes, copper pipes, stainless steel pipes, etc. After a few years of use, galvanized pipes will corrode and breed bacteria, which is harmful to human health and cannot be used for drinking water pipes; copper pipes and stainless steel pipes are more expensive and difficult to construct. difficulty. Plastic pipes include PVC pipes and PE pipes, and plastic composite metal pipes include aluminum-plastic composite pipes. Due to the variety of plastics, the market quality is uneven, and additives such as phthalein are often used in the plastic production process, which can cause cancer, kidney damage, and destroy hum...
