Rapid feedback type constant-temperature adjusting valve based on water temperature in constant-temperature pipeline, constant-temperature heat exchange system with same and constant-temperature water mixing device

Abstract

The invention discloses a rapid feedback type constant-temperature adjusting valve based on the water temperature in a constant-temperature pipeline. The valve comprises a constant-temperature pipeline and a high-temperature pipeline for adjusting the water feeding amount according to the water temperature in the constant-temperature pipeline, a valve base and a valve element matched with the valve base are arranged in the high-temperature pipeline, a temperature bulb used for sensing the water temperature inside the constant-temperature pipeline is arranged in the constant-temperature pipeline, the temperature bulb penetrates through the pipe wall of the constant-temperature pipeline to drive the valve element to move to adjust the size of a channel between the valve element and the valvebase so as to adjust the water feeding amount of the constant-temperature pipeline. According to the rapid feedback type constant-temperature adjusting valve based on the water temperature in the constant-temperature pipeline, the temperature bulb directly senses the water temperature in the constant-temperature pipeline, detection is accurate, the valve element is directly driven through thermalexpansion and cold contraction of the temperature bulb to rapidly adjust the high-temperature water flow, the adjusting feedback time is short, the constant temperature can be controlled only througha control device, the structure is simple and compact, constant temperature is achieved, meanwhile, the number of needed parts is reduced, and the cost is reduced.

Description

technical field [0001] The present invention relates to a device for regulating the constant water temperature in a pipeline, its constant temperature heat exchange system and constant temperature water mixing device, in particular to a constant temperature regulating valve based on fast feedback of water temperature in a constant temperature pipeline, its constant temperature heat exchange system and constant temperature water mixing device . Background technique [0002] In the fields of HVAC and showers, it is often necessary to adjust the constant temperature pipeline to be fixed at a constant temperature. The prior art uses a thermostatic mixing valve to achieve this purpose. The thermostatic water mixing valve is not only complex in structure, but also high in cost; take the "floor heating mixing device" with the patent number 201310155066.3 as an example, such as the figure 1 As shown, the floor heating mixing device not only needs a temperature bulb and a complex wa...

Problems solved by technology

The thermostatic water mixing valve is not only complex in structure, but also high in cost; take the "floor heating mixing device" with the patent number 201310155066.3 as an example, such as the figure 1 As shown, the floor heating mixing device not only needs a temperature bulb and a complex water mixing component when adjusting the constant temperature of the pipeline, but also needs to transmit signals through a pressure guiding tube between the temperature bulb and the mixing component. The overall structure is complex, and not only It occupies a large space, it is not convenient to install and arrange pipelines, and there are many parts and high cost

In addition, the constant temperature mixing valve in the prior art can only be used to achieve constant temperature through the mixing of high and low temperature water, but cannot achieve constant temperature through heat exchange between two independent high and low temperature piping systems
