Problems solved by technology
[0002] Most of the control parts of the temperature control valves in the prior art are made of bimetallic sheets, which makes the existing temperature control valves larger in size, complex in structure, poor in temperature control accuracy and low in sensitivity, resulting in a large waste of energy
[0003] Moreover, some current temperature-controlled automatic valves generally cannot adjust the flow rate, so when used in some special locations, the valve can only be replaced or the system can be readjusted.
In addition, different places and different indoor locations have different requirements for temperature changes. At present, the sensitivity and temperature of the valve cannot be replaced and adjusted once it is set, which leads to the inconsistency in the use of temperature-controlled automatic valves. convenient

Embodiment Construction
[0023] See Figure 1-Figure 4 , figure 1 Shown is a schematic diagram of the temperature-controlled automatic valve in one of the states according to the present invention; figure 2 Shown is the schematic diagram of the valve body of temperature control automatic valve according to the present invention; image 3 Shown is a schematic diagram of the memory alloy elastic element and the sliding block according to the present invention. The invention provides a temperature-controlled automatic valve. The temperature-controlled automatic valve has a plurality of sub-valves, and each sub-valve includes a valve body 1, a sliding block 3 and a memory alloy elastic element 1, wherein the sliding block 3 is a valve core.
[0024] In addition, the memory alloy elastic element mentioned above can be made of, for example, nickel-titanium alloy, copper-nickel alloy, copper-aluminum alloy, copper-zinc alloy, stainless steel or other memory alloy materials well known to those in the field...

The invention provides a temperature control automatic valve which is provided with a plurality of valve branches. Each valve branch comprises a valve body, a sliding block and a memory alloy elastic element. A first cavity, a second cavity and a third cavity are arranged on each valve body, the first cavities are communicated with the third cavities, and the second cavities and the third cavities can be communicated through open holes. The sliding blocks are provided with first ends and second ends opposite to the first ends and arranged in the third cavities. The memory alloy elastic elements are provided with third ends and fourth ends opposite to the third ends and arranged in the third cavities, the third ends abut against the first ends of the sliding blocks, and the fourth ends abut against fixing pieces. When the memory alloy elastic elements are in a first state, first gaps are formed between the second ends and the open holes. When the memory alloy elastic elements are influenced by temperature to be in a second state, the sliding blocks are driven by the memory alloy elastic elements to move in the first direction so as to form second gaps between the second ends of the sliding blocks and the open holes in an adjusting mode. The temperature control automatic valve can control flow according to temperature changes.
Description
technical field [0001] The invention relates to a temperature-controlled automatic valve, in particular to a temperature-controlled automatic valve capable of controlling flow. Background technique [0002] Most of the control parts of the temperature control valves in the prior art are made of bimetallic sheets, which makes the existing temperature control valves larger in size, complex in structure, poor in temperature control accuracy and low in sensitivity, resulting in a large waste of energy. [0003] Moreover, some current temperature-controlled automatic valves are generally unable to adjust the flow rate, so when used in some special locations, the valve can only be replaced or the system readjusted. In addition, different places and different indoor locations have different requirements for temperature changes. At present, the sensitivity and temperature of the valve cannot be replaced and adjusted once it is set, which leads to the inconsistency in the use of tem...
