１１５に手動調節栓１１８を設けている。Configuration of conventional examples and their problems Temperature-sensitive valves that adjust the flow rate of fluids such as heating medium or cooling water depending on their temperature are widely used. It consisted of a temperature-sensitive body and a valve body that moved according to the displacement of the temperature-sensitive body. 1st
The figure shows a conventional example (Japanese Utility Model Application No. 67-119244) used in a hot water supply circuit for an instantaneous water heater. Therefore, the pipe 101 has a hot water inlet 102, a cold water inlet 103, and a mixed hot water outlet 104, and a heat sensitive body 105 is supported in the hot water side passage, and a shaft 106 protrudes from the heat sensitive body 105 by a length depending on the temperature. is starting to change. A valve body 107 is fixed to the shaft 106 and corresponds to a fixed valve seat 108 provided in the conduit 101, so that its opening area can be changed. 109 is a support member 11 that keeps the heat sensitive body 105 away from the fixed valve seat 108.
It is a spring that is pushing in the direction of 0. These parts constitute a temperature-sensitive control valve 111. FIG. 2 shows a circuit of an instantaneous water heater using the valve shown in FIG.
2 branches into a heating path 114 that passes through a heat exchanger 113 and a cold water path 115 that bypasses it, and later merges and is supplied from a hot water supply path 116 to a faucet 117. A temperature-sensitive control valve 111 is provided in the middle of the heating path 114, and manual adjustment valves 118 are provided in the cold water channels 3 and 115.
この従来例は、加熱路１１４の湯温か上昇すれば軸’１
０６の突出量が増加して開口面積を増して流量を増加す

はほぼ一定に制御される。この結果、バイパスする冷水
路１１５の手動調節栓１１８の操作で冷水量を調節すれ
ば任意の湯温か得られることになる。In this conventional example, when the temperature of the hot water in the heating path 114 rises, the axis '1
When the amount of protrusion of 06 increases, the opening area increases and the flow rate increases, and if the hot water temperature decreases, the flow rate decreases. Therefore, if the combustion input is constant, the temperature rise is approximately inversely proportional to the flow rate, so the temperature from the heating path 114 is controlled to be approximately constant. As a result, any hot water temperature can be obtained by adjusting the amount of cold water by operating the manual adjustment valve 118 of the bypass cold water channel 115.

場合に温度応答性が悪く使い勝手に不便を生じる場合が
あった。In such a temperature-sensitive control valve, there is a delay in response until the heat is transferred to the wax, liquid, or gaseous expanding substance sealed in the temperature-sensitive body 105, and the valve cannot be used properly unless the design points are selected carefully. There is a risk of causing an oscillation phenomenon in which the circuit closes and opens, and when used in a conventional hot water supply circuit, the temperature response may be poor and the usability may be inconvenient.
又、感温体と弁体を管路中に設けるため寸法が大きくな
り、実装上も不都合なものであった。Further, since the temperature sensing element and the valve body are provided in the pipe, the size becomes large, which is inconvenient in terms of mounting.

るから小流量の制御や閉塞性に優れている。Effects of the Invention With the above-described configuration, the coil in the flow path receives the entire temperature directly and matches the fluid temperature very quickly, and since it is made of a shape memory material, it simultaneously changes to the dimensions when it was previously subjected to memory treatment. Since the gap between the coil wires serves as a valve passage, a change in dimensions simultaneously causes a change in the valve passage, thereby regulating the flow rate. In addition, when the coil is contracted, the outer diameter or inner diameter of the free end comes into close contact with the passage wall, thereby controlling the flow rate leaking from the gap between the free end and the passage wall, making it easy to control small flow rates and prevent blockage. Are better.

A coil 4 supported by the coil 4 is inserted. This coil 4
is made of shape memory material and expands and contracts in the axial direction depending on the temperature. A valve passage 5 opening in the radial direction of the coil 4 corresponds to a gap 6 between the wires of the coil 4, and fluid flows through this gap 6. Also, the free end 7 of the coil 4

The valve housing is composed of upper and lower parts 1 and 1', and has a trapezoidal coil 4 whose one end 3 is supported by a stator 2 sandwiched between them. A valve passage 5 provided in the same direction as the axial direction of the coil 4 corresponds to a gap 6 between the strands of the coil 4, through which fluid flows. In the contracted state as shown in FIG. 6, the outer diameter of the free end 7 is in close contact with the passage wall 8.

Here, the same members are given the same numbers as in the second embodiment, but the difference is that the trapezoidal coil 4 is supported at one end 3 of the larger diameter, and when contracted, the smaller diameter end 3 is supported. This is the point at which the free end 7 of the stator 2 comes into close contact with the passage wall 8 of the central protrusion of the stator 2.

ている。Effects of the Embodiments In the embodiments described above, the coil 4 is made of a reversible shape memory material, and expands and contracts near the temperature at which it has been memorized in advance. Therefore, since the gap 6 changes depending on the temperature of the passing fluid, the flow rate control effect is achieved by changing the passing area by 7 basis points without providing a separate valve body. Also, coil 4
Since it is exposed in the flow path, it has a wide contact area with the fluid and has the effect of being able to respond extremely quickly to temperature changes.
良く知られているように、コイルはその長さを収縮させ

従って第１の実施例及び第２の実施例では収縮時にコイ
ル素線間の隙間６が互に密着すると共に通路壁８に対し
ても密着することになるので少流量域から密閉まで制御
性が優れている。Therefore, in the first and second embodiments, when the coil wires are contracted, the gaps 6 between the coil wires come into close contact with each other and also with the passage wall 8, so that controllability is achieved from a small flow range to a sealed area. Are better.

という各々の効果を有している。In the first embodiment, the structure of the stator 2 and the nozzle 1 is simple, in the second embodiment, the conduit can be formed in a straight line, so connection is easy, and in the third embodiment, the coil 4 Since the passage wall 8 is formed on the stator 2 itself that holds the coil 4, it is easy to align the centers of the coil 4 and the passage wall 8, and the leakage flow rate is small especially at a position where the flow passage area is narrow, resulting in good controllability. Each has its own effects.

ルの素線間隙間を流路の調節に用いるものであるから、
温度変化に対する応答性が早く、別途弁体を必要としな
いので全体が小型化できる効果がある。Effects of the Invention Since the present invention uses the gap between the strands of a coil made of a shape memory alloy with one end fixed to adjust the flow path,
It has a quick response to temperature changes and does not require a separate valve body, which has the effect of making the entire device smaller.

量の変化を補正する目的にも適した弁である。For example, this temperature-sensitive control valve enables high-temperature heat collection by inserting it into a solar heat collection circuit and opening when the temperature reaches a certain level, or by inserting it into the cooling water circuit of a cooling tower and reaching a temperature above a certain level. It is suitable for the purpose of preventing wasteful circulation of cooling water by keeping it closed, or inserting it into the hot water supply circuit as described in the conventional example to stabilize the hot water temperature by high-speed response. Further, the valve is suitable for inserting into a liquid fuel supply path to correct changes in combustion amount caused by changes in viscosity caused by changes in ambient temperature.

るという効果をも有している。In addition, water flow noise is often generated when the valve is extremely constricted, so measures have been taken to provide a porous body immediately after the constriction part or to divide the valve body into a number of passages. . In the present invention, since the gap between the coil wires is used as a constriction part, the passage is divided into a large number of nine pages, and as a result, it also has the effect of reducing water flow noise.
