Secondary water supply system

Abstract

The invention discloses a secondary water supply system. The system comprises a tap water inlet pipe, a Y-shaped filter on the tap water inlet pipe, a surge tank, a pressure water tank and a variablefrequency pump; a water inlet of the surge tank is connected to the tap water inlet pipe, a water outlet of the surge tank is connected to a water inlet of the variable frequency pump through a connecting pipeline, a water outlet of the variable frequency pump is connected to a water supply pipeline of user equipment, the water supply pipeline is connected with the pressure water tank, and the pressure water tank is connected to an air compressor through a compressed air port; a water quality detection sensor is installed at the water inlet side of the surge tank, a plurality of ultraviolet lamp pipes are annularly arranged in the surge tank along an axis, installed from one side of the surge tank and fixedly connected with a connecting base arranged at the inner side of the surge tank through a lamp holder plate, and a protective cover is arranged outside the lamp holder plate. According to the secondary water supply system, tap water is directly introduced into the user equipment foruse, external pollution sources cannot enter the tap water, and the water use safety of a user is ensured.

Description

Technical field [0001] The invention relates to the technical field of water supply, in particular to a secondary water supply system. Background technique [0002] Existing secondary water supply generally uses surge tanks and air pressure tanks for fully enclosed water supply to solve the problem of secondary pollution caused by the use of water tanks, and achieve energy-saving functions through diaphragm air cylinders to reduce frequent start-ups of variable frequency pumps . The reclaimed water of the surge tank in the existing closed water supply system cannot be effectively disinfected, and the water from the surge tank cannot be guaranteed to be safe water. In addition, the existing gas pressure tank includes a tank body and a diaphragm inside the tank. . However, because the existing air pressure tank adopts a diaphragm structure, and the diaphragm is made of rubber material, it is easy to use for a long time, because the water in the tank cannot enter and exit, forming...

Problems solved by technology

The reclaimed water in the surge tank in the existing closed water supply system cannot be effectively disinfected, and the water coming out of the surge tank cannot be guaranteed to be safe water. In addition, the existing air pressure tank includes a tank body and a diaphragm inside the tank

However, because the existing air pressure tank adopts a diaphragm structure, and the diaphragm is made of rubber materials, it is easy to form quasi-dead water during long-term use because the water in the tank does not flow in and out, and biofilms are formed on the melted water surface of the standard diaphragm. Long-term operation will breed various bacteria and produce smelly water, which has water safety problems
