Description

Temperature control valve

Technical field

The utility model relates to a kind of Temperature control valve, relates in particular to a kind of Temperature control valve that keeps temperature constant.

Background technique

Along with the exhausted day by day and people of non-renewable energy resources different demands to ambient temperature in living, the Temperature control valve that often needs a kind of not only steady temperature but also can artificially regulate on demand.And existing valve can only or open or close, and causes a large amount of energy to be consumed for no reason, also makes the user increase the heating cost.

There is a kind of marmem extremely to be suitable for use in this Temperature control valve, because this alloy has a phase transition temperature.When under phase transition temperature, alloy is a martensite, and imposed load is easy to distortion; After surpassing phase transition temperature, alloy undergoes phase transition, and becomes austenite, returns to the setting shape in its " memory "; And be cooled to once more under the phase transition temperature, alloy is got back to deformation state again.This character makes it have responsive to temperature and drives two kinds of functions, and this is applied in can be quite simple and convenient in the valve, and more more reliable as the thermometer bulb technology of temperature-sensitive material than existing employing paraffin etc.Heating thermostatic valve as disclosed a kind of can regulate temperature in the Chinese utility model patent 01260069.5 has just utilized marmem as core parts.In addition, this patent is also separated valve body and drive part, and memory alloy drives the magnetic post by magnetic interaction and comes switch valve, thereby has avoided the problem of leaking to a certain extent.But also can artificially set the stationary temperature of wanting by the decrement of regulating memory alloy spring.

But because memory alloy can only be regulated in certain temperature range, between said 18 ℃～22 ℃, this just brings problem of the adjusting of temperature section more than in for example above-mentioned patent.For example when people are in the room, need room temperature constant at 20 ℃; But when people withdraw from a room, may only need it not to be lower than 10 ℃ or constant about a certain lower temperature, with energy saving.Had technology to adopt two memory springs to regulate temperature, the thermoregulation range of one of them room temperature memory spring is near 20 ℃, and another low temperature memory spring is then regulated ambient temperature near 10 ℃, so just can realize the adjusting of two temperature section.But this technology is with two memory spring diverse locations at valve arranged apart, the room temperature memory spring is positioned on the valve body, its temperature is consistent with ambient temperature, the low temperature memory spring is then between valve and valve body, the water temperature that flows through in its temperature and the valve is relevant, low temperature memory spring practical adjustments be water temperature and heat flow.Like this, just must come to determine the true thermoregulation range (may be more much higher than 10 ℃) of low temperature memory spring by experiment, the variation of actual water temperature will make can be too inaccurate to the adjusting of temperature.And this true thermoregulation range also depends on concrete water temperature, and different regions heating water temperature and different, so need make different memory springs to different water temperature sections, this has increased cost and the complexity made.

In addition, the magnetic control that the drive portion branch utilizes in the existing Temperature control valve is made of less, may cause valve invalidation under the bigger or unsettled situation of hydraulic pressure.
