As shown in fig. 1, 2, 3 and 4. In this particular embodiment, the flow regulating valve 10 includes a temperature-sensitive drive device 1 and a valve body member 200, wherein the temperature-sensitive drive device 1 includes a drive member 100 and a temperature-sensitive member 300.

The bellows member 140 forms a pressure driving chamber 110 with the upper and lower cases 131 and 132.
The driving part 100 comprises a driving piece 120, the driving piece 120 comprises a first driving piece 121 and a second driving piece 122, the first driving piece 121 is partially arranged in the inner cavity 133 of the cover body and is abutted against the end 141 of the corrugated pipe 140, and the second driving piece 122 is partially arranged outside the inner cavity 133 of the cover body. In this embodiment, the first driving member 121 and the second driving member 122 have a substantially circular rod-shaped structure, and the first driving member 121 and the second driving member 122 are fixedly connected by internal and external threads. Of course, the first driving member 121 and the second driving member 122 may be engaged by an abutting manner to transmit pressure and simultaneously axially displace; the first driving member 121 and the second driving member 122 may be formed as an integral structure.
The valve body member 200 includes a valve body 210, the valve body 210 defines a valve cavity 260, the first flow port 240 communicates with the valve cavity 260 through the valve port 230, and the second flow port 250 communicates directly with the valve cavity 260.
The valve body 210 is fixedly connected with the housing 130, and the valve core 220 is disposed in the valve cavity 260 of the valve body member 200. The second driving member 122 extends into the valve cavity 260 and is fixedly connected with the valve core 220 through threads, and of course, the second driving member can be matched in an abutting manner to transmit pressure and can axially displace at the same time.
The temperature sensing member 300 includes a cylindrical bulb 320, and an inner cavity of the bulb 320 serves as a temperature sensing chamber 310. The first end 420 of the capillary tube 400 extends into the temperature sensing chamber 310 and is welded and fixed with the temperature sensing bulb 320; the second end 430 of the capillary tube 400 extends into the pressure-driven chamber 110 and is welded to the upper housing 131. The temperature sensing chamber 310 is in sealed communication with the pressure driving chamber 110 through the inner bore 410 of the capillary tube 400. The temperature sensing medium 500 is in a multiphase state, including a liquid temperature sensing medium 500a and a gaseous temperature sensing medium 500b.
In general, in the installed state of the temperature-sensitive driving device, the temperature-sensitive member is disposed at a position higher than the position of the driving member, the temperature-sensitive chamber 310 of the temperature-sensitive member 300 is disposed at a position higher than the position of the pressure-driven chamber 110 of the driving member 100, and the temperature-sensitive chamber 310 is in airtight communication with the pressure-driven chamber 110. Therefore, the temperature sensing medium 500 fills the receiving chamber defined by the temperature sensing chamber 310, the pressure driving chamber 110, and the inner hole 410, the liquid medium 500a is disposed at the lower portion of the temperature sensing chamber 310, and the gaseous medium 500b is disposed at the upper portion of the temperature sensing chamber 310.

As set forth above, the temperature sensing bulb 320 is disposed in the temperature detection area, and is effective for detecting temperature variation and changing the temperature variation into temperature sensing medium pressure variation in the temperature sensing cavity 310 through the conversion of the gas-liquid two-phase state. The temperature sensing medium in the temperature sensing chamber 310 passes through the temperature sensing medium in the inner hole 410 again, and transfers the pressure change to the medium in the driving chamber 110.
The medium in the temperature sensing cavity directly senses the temperature change, so that the larger the volume ratio of the volume of the temperature sensing cavity 310 to the total volume is, the larger the ratio of the temperature sensing medium directly sensing the temperature change is, the pressure loss in the pressure transmission process is reduced, and the detection sensitivity is improved.
The port 440 at the first end is below the liquid level, so that the inner hole 410 and the pressure driving cavity 110 are kept as liquid media, the pressure change of the temperature sensing cavity is transmitted to the driving cavity in a hydraulic mode, and the transmission fluctuation is small; in addition, the pressure change is easy to generate, so the proportion of the volume of the temperature sensing cavity to the total volume is large,
with the temperature-sensitive driving device with the structure, the volume of the temperature-sensitive cavity 310 is larger than 0.5 times of the volume of the accommodating cavity defined by the inner hole 410, the temperature-sensitive cavity 310 and the pressure driving cavity 110, so that the sensitivity of detection can be improved, and the pressure loss ratio can be reduced.
