Abstract
The utility model relates to a temperature-control valve for a water heater, adopts the copper-based shape memory alloy as the temperature-controlling switch element of the temperature-control valve for the water heater, and utilizes the characteristic of the shape memory alloy to control automatically the opening and the closing of the temperature-control valve for the water heater. The temperature-control valve having simple structure and low cost can be served as the temperature-controlling switch valve used in various water heaters, can be popularized, and can be used particularly in the area without the electricity and the zone which is short of the electricity.
Description
The utility model belongs to the temperature detect switch (TDS) valve that uses in the heating system.
The water heater thermostat valve divides active and passive two kinds, active thermostat valve adopts electric contact thermometer, compositions such as temperature control level meter, solenoid valve, this class valve is big to the control range of water temperature, the temperature-controlled precision advantages of higher, but package unit costs an arm and a leg the maintenance difficulty, need with power supply control, so be difficult to promote the use of at nothing electricity, power outage area.Passive thermostat valve adopts the volumetric expansion of low-boiling point liquid when vaporization or paraffin wax fusing to promote valve open, this valve processing technology complexity, liquid easy to leak, shortcoming such as sensitivity is low.
For overcoming the shortcoming of above-mentioned thermostat valve, reduce fabricating cost and enlarge application and area, the utility model proposes a kind of water heater thermostat valve of making switching element with marmem.
The water heater thermostat valve that the utility model is alleged, form (seeing shown in Figure 1) by front valve shell 1, rear valve body 3 and temperature detect switch (TDS) assembly 2, switch valve block on the temperature detect switch (TDS) assembly is made with copper-based shape memory alloy, the temperature detect switch (TDS) assembly can be connected with the front and back valve body with flange, and also the form of available union is installed.
The temperature detect switch (TDS) assembly 3 of water heater thermostat valve is by connecting plate 4, sealing gasket 10, elastic valve plate 7, switch valve block 5, and fixed card 6 is formed (seeing shown in Figure 2).Fixed card 6 is equipped with on elastic valve plate 7 tops, the bottom is fastening with screw 8 and connecting plate 4, elastic valve plate 7 is equipped with sealing gasket 10 with the periphery in connecting plate aperture, and an end of switch valve block 5 penetrates fixed card and elastic valve plate is adjacent to, and the other end is fastening with screw 9 and elastic valve plate 7 connecting plates 4.Connecting plate adopts 1-10mm thick hard temperature-resistant material such as copper, aluminium, stainless steel or moulds firmly and make, and has the hole that heat supply water flows through on the plate, and hole shape can adopt triangle, circle, square or rectangular opening; It is stainless steel or the beryllium bronze of 0.1-2.5mm that elastic valve plate 7 adopts thickness, and tin-phosphor bronze is made.Switch valve block 5 usefulness copper-based shape memory alloys are made, throttle slice thickness is 0.05-10mm, earlier alloy is made shape as shown in Figure 2, the back in the time of 750 ℃-880 ℃ through Quenching Treatment, in 70 ℃-100 ℃ hot water and 0 ℃ of-5 ℃ of cold water, after the circuit training, be contained on the connecting plate again.When water temperature reached a certain temperature in the valve, the 5 distortion deflections of switch valve block had been lifted up together with elastic valve plate 7, and valve passage is opened, and hot water flows from right to left through the thermostat valve switch block.After water temperature descended, switch valve block 5 recovered shape shown, with the through hole sealing, blocked current under the effect of elastic valve plate.
On front valve shell 1 and rear valve body 3, all open a screw among Fig. 1; in order to hot-water line in the self-loopa to be installed; this be because; when hot water flows to the thermostat valve switch block, lower in water temperature near switch valve block place, cause valve in time not open; release in the water self-loopa backheat hydrophone that must this part temperature is lower; this hole connects with tee union, and another mouth can be used as time spent not in winter, manually release cold water in the water heater with the protection water heater not by bursting by freezing.
