Title:
BRANCH HEADER MADE OF PLASTIC RESIN AND HORTICULTURAL HOUSE DEEP LAYER UNDERGROUND HEAT STORAGE HEATING SYSTEM
Document Type and Number:
Japanese Patent JP2015197218
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an underground heat storage heating system constructed by a piping system in which branch pipes are connected to a facility horticultural house without using any tools and buried, a flow rate adjustment for each of the branch pipes can be smoothly carried out, it may not be deformed during long period of usage in its buried state, no air-lock occurs and it does not make a right-angled loop.SOLUTION: This invention is constituted in such a way that: one end of a tubular branch header 1 made of plastic resin is provided with a pipe joint 10k for a main pipe; a plastic resin pipe 40 of middle diameter is easily connected through a rotary advancing motion of a cap 12; groups of a plurality of branch portions 11 are protruded from one side surface of a header shaft part 10; a flow rate adjustment for each of flowing water circuits is easily carried out through rotation of cores 22 in a flow rate adjustment segment 2 arranged at the central part and at the same time an integral shaped branch header 1 capable of easily connecting small-diameter plastic resin pipes 41 is buried and arranged in the ground through rotary advancing motion of a cap 3 toward the pipe joints 11k for branch pipes at the rear ends of the branch portions 11; and the small-diameter plastic pipes 41 in each of the flowing water circuits are arranged at a deeper position than that of the header 1 so as to perform a smooth air removal from the system.
