Interface card of water collecting and diversifying device

Abstract

A water collecting and diversifying device has an interface card which is a flange card comprising an outer tooth and an inner tooth; the outer tooth and the inner tooth are of isosceles trapzoid shapes; the tooth root of the inner tooth and the tooth root of the outer tooth are staggered; the outer tooth clearance bottom part of the outer tooth is of a fillet; the inner tooth clearance bottom part of the inner tooth is of a rectangular angle; a longitudinal section surrounding a flange circle center for the interface card of the water collecting and diversifying device is provided with a section shape of an obtuse angle shape; the material quality is stainless steel 301 or 302 with hardness of HV400-420, a tensile strength of the card is 1MPa, and elongation is 1%. The card has a simple structure, can be convenient to realize the connection of an interface and the pipeline of the water collecting and diversifying device, and is very simple to install and operate.

Description

Technical field [0001] The invention relates to a pipe fitting, in particular to an interface card used in a manifold for connecting pipes. Background technique [0002] In the field of water heating equipment, the water manifold is used to divert and guide the water in the water pipes, and various water heating pipes need to be connected at the interface of the water manifold. For the current sub-catchments, most of them are assembled by metal parts or forged as a whole, and then connected through thread fit. For the sub-catchments that use ball valves to realize the connection of the branch circuit, the market share is relatively large, but it is prone to bursting; The sub-catchment is connected by a ferrule for the road interface. The processing and installation are relatively cumbersome, and the requirements for the inner diameter of the heating tube are high. [0003] In addition, for the above-mentioned connection methods, there are mainly the following disadvantages:...

Problems solved by technology

For the current sub-catchments, most of them are assembled by metal parts or forged as a whole, and then connected through thread fit. For the sub-catchments that use ball valves to realize the connection of the branch circuit, the market share is relatively large, but it is prone to bursting; The sub-catchment is connected by a ferrule at the road interface, the processing and installation are relatively complicated, and the inner diameter of the heating tube is required to be high

[0003] In addition, for the above-mentioned connection methods, there are mainly the following disadvantages: the structure is complex, not only the cost is high, the processing and installation are also troublesome, and it is easy to scale, and the heat dissipation is large; the interchangeability is not good, and the manufacturers' The production capacity is different, and the pipes themselves have different specifications, and the current sub-catchment interface has higher requirements for the pipe specifications, so it is difficult to replace the pipes with each other
