Hot and cold water isolation mounting

Technical field

The utility model relates to a kind of isolation mounting, relates in particular to a kind of hot and cold water isolation mounting that utilizes the proportion design of water.

Background technique

Along with the continuous progress of society and scientific and technical development, people are more and more concerned about the earth that we depend on for existence now, and most countries has also been fully recognized that the significance of environment to our human development in the world.Each state is all taking active and effective measure to improve environment, reduces and pollutes.This is wherein important is also that the most urgent problem is exactly energy problem, to fundamentally solve energy problem, except finding the new energy, energy-conservation be crucial be also the most effectively important measures at present, in recent years, by effort, people have obtained huge achievement in the research of power-saving technology and product development.

And hot water engineering is as a novel industry, it is no longer also " boiler " aspect that simply rests on highly energy-consuming.Along with the reinforcement of people's environmental consciousness, as far as possible to environment destroy less, the hot water engineering of non-destructive new energy, green energy resource becomes the main flow in this field gradually.Such as: solar heating engineering, heat-pump hot-water engineering etc.But specifically transporting in using process of hot water engineering, it between the heating system of hot water and intake pipe or outlet conduit, is the situation in being communicated with always, in the situation that not carrying cold/hot water, water in pipeline can be progressively cooling, and logical heat transfer drives the hot water in heating system to dispel the heat together, cause heating system need to consume the more energy, just can make hot water reach assigned temperature, cause the problem of energy waste.

For this reason, people can increase by an one-way valve between heating system and intake pipe or outlet conduit, it is just communicated with under in working order, yet shares the heating system of pipeline water inlet and outlet for those, but still have the problems referred to above, energy waste cannot be avoided.

Model utility content

The purpose of this utility model is to provide a kind of can prevent that in pipeline, hot and cold water mixes the hot and cold water isolation mounting dispelling the heat.

The hot and cold water isolation mounting that the utility model provides, comprise upper connection pipe, lower contact pipe, circular orientation pad, proportion is less than the floating spool of water and the sinking spool that proportion is greater than water, the internal diameter of described circular orientation pad is less than the internal diameter of upper connection pipe and lower contact pipe, at floating center spool, have a through hole, this through hole internal diameter is less than the internal diameter of circular orientation pad, described sinking spool comprises axle core and is evenly distributed on the axially locating wing of this axle core upper end surrounding, described axle core edge is enclosed within through hole and can in this through hole, slides up and down, described lower contact pipe is movably arranged on upper connection pipe below, described circular orientation pad is installed between adaptor tube and lower contact pipe, the upper-end surface of described floating spool and the bottom surface of circular orientation pad are connected and are suspended in the upper end of lower contact pipe, the lower end of described axle core is arranged in through hole through circular orientation pad, the upper end of described axle core is connected and is sunk to the bottom of upper connection pipe by the axially locating wing and circular orientation pad end face.

On the end face of described floating spool bottom, have an annular groove.

In the upper end of described axle core, have a counterbore.

For prevent from floating spool or sinking spool are gone out lower contact pipe or upper connection pipe under the impact of current, inside the inner side, upper end of described upper connection pipe and the lower end of lower contact pipe, be all provided with a gear platform.

For being better tightness of the present utility model, between described upper connection pipe and lower contact pipe, a seal ring is also installed.

For making the utility model be easy to open, clean, between described upper connection pipe and lower contact pipe, by a loose joint nut, be connected.

The utility model is to utilize the proportion difference of each spool and water to design, when there is no water flow, floating spool is suspended in lower contact pipe and withstands circular orientation pad, sinking spool sinks to upper connection pipe top and pushes down circular orientation pad, and axle core inserts the isolation that completes water in upper and lower adaptor tube in through hole; When having water to flow from the top down, can make progress from the region forming between axle core, circular orientation pad and each axially locating wing end face of float valve core of current is implemented a downward thrust, promote that floating spool moves downward until axle core away from through hole, current flow through in through hole; When having water to flow from bottom to top, current can be implemented the thrust making progress from the axle core bottom surface to sinking spool, promote that sinking spool moves upward until axle core away from through hole, current flow through from the region forming between axle core, upper connection pipe and each axially locating wing, can forward and reverse one-way flow thereby realize.The utility model is simple in structure, rely on the mobility of water can be voluntarily switch forward or backwards, not only energy-conservation but also environmental protection, can be widely used between the heating system and pipeline of large-scale hot water engineering, domestic water-storage formula solar water heater, be particularly suitable between the heating system and pipeline of the shared same pipeline of water inlet and outlet.
