Description

Technical Field

[0001] This invention relates to the field of pipeline water supply equipment technology, and more particularly to a narrow-mouth square flow meter distributor. Background Technology

[0002] In fluid transport systems, manifolds are key devices for fluid diversion and distribution, widely used in underfloor heating, tap water supply, and temperature regulation. Manifolds are widely used as fluid control devices in heating and water supply pipeline systems. By installing operating valves on each branch, users can control the on / off state and flow distribution of each branch according to their needs, thereby achieving independent regulation of the medium supply to different areas or terminal equipment. With the increasing demands for quality of life and the development of industrial production, higher requirements are being placed on the performance, service life, and ease of operation of manifolds.

[0003] However, existing square manifolds have defects that limit their application scenarios: First, the square main pipe is directly formed from square tubing, and the front and rear ends of the pipe are then reduced in size and connected to the support, resulting in large deformation of the pipe wall, thinning due to stretching, and reduced strength. Under long-term pressure, it is prone to cracking and leakage. Second, the threads connecting the main pipe to the external system are directly machined on the main pipe wall. The pipe wall is already thin, and it becomes even thinner after threading, which cannot meet the requirements of the go / no-go gauge. It is prone to stripping and breakage, resulting in poor sealing and reliability. The base of the flow meter, automatic valve core, and adapter uses an internal stretching and tapping process, resulting in thin inner walls and poor strength. It is prone to cracking when tightening, leading to internal leakage and seepage, making it difficult to guarantee system stability. Third, the inlet and return main pipes are located on the same plane. When the branch connectors are installed downwards, they are prone to interference with the return main pipe below, resulting in difficult installation, troublesome disassembly, and even technical problems that require disassembling the main pipe for maintenance.

[0004] In conclusion, there is an urgent need for a narrow-mouth square flow meter distributor to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a square flow meter distributor with a narrowed nozzle.
